Battery Mod + Solar Cell - Nexus 5 Accessories

Hello everybody, first post on XDA!
I am planning to mod my Nexus 5 battery. Considering that the dimension of the original battery is 57mm*60mm, I planned to buy 4 Sanyo 3,7V 840mAh and connecting them in parallel. I would like to post links but as a newbie I am not allowed to do so.
These are 14mm in diameter and 50mm long, meaning that 4 of them would be packed in 56mm*50mm, with 10 extra free mm where I can comfortably fit the "charging board" that I can unsolder from the old original battery. The problem here is that the charging board will probably have more than 2 pins, the others being for temperature and data. How can I deal with them? I haven't teared my battery yet, so I cannot see how the chip really looks like. Does someone know whether the data pins end up in the circuitry or are they somehow connected to the battery itself? Because in this latter case I would really have no idea how to deal with these extra pins...
In addition how will the circuitry and the phone itself deal with the increased capacity? Should I tell the phone the capacity has changed or will it auto adapt? I have read tons of posts on this topic, all saying different things...
Certainly that will increase the phone thickness and I plan on 3D printing a custom designed back-cover. Luckily the original 3D model is downloadable from GrabCAD for free, that is a good starting point. What material would you suggest me to print it in? PLA, ABS, Nylon?
Furthermore, I am planning to add a nerdy solar cell 4v, 35mA that will certainly do basically nothing except help in real emergency charging the phone while off, but it will give an awesomly nerdy look. The solar cell I am talking about is 32mm*39mm and would perfectly fit on the right of the camera.
I could fit a 100mA solar panel, or avoid the battery mod at all and just fit 5 of those solar panel for a summed max current of 175mA...
I plan charging the battery with direct connection of the solar panel to it through a diod. The only thing that worries me is that while 35mA are less than what the phone draws during standby, the battery indicator will never go crazy seing the battery tension growing while no charger is plugged in. On the other hand, higher currents, will actually be able to actively recharge the phone creating confusion to the phone that would not be able to realize what is going on. To avoid that I should connect the solar panels to the usb charging port. That would put the phone into charging mode and thus in a energy hungry more that could again cause battery to drain instead of charging or anyway to charge incredibly slow.
If someone is interested in this project and has suggestions of any kind I will appreciate and I will share the results.

Firstly I would scrape the idea of a solar cell, it's going to generate very very little power especially since its going to be pointed down. Also that 175mA is probably going to be something smaller in the real world even under ideal condition it'll be almost impossible to generate that. Now for the batteries you would like to put into your phone, you have to open up your phone or find dimensions and see how everything fits together. Sometimes their will be some space around the battery and this is put for several safety reasons, so I do not recommend filling up the space if you go ahead with this replacement. This could lead to battery overheating which could cause it to leak and cause a short and destroy your phone. At the end of the day I really wouldn't recommend anything attempt this unless you really know what you're doing and the risks involved with doing this. I don't feel the increase in battery life would offset the risk factor of attempting this. Also I should mention that when you solder that it's going to be very fine and sensitive solder work, there are many things on that board that will be heat sensitive and power sensitive so using something like a $50 Weller wouldn't be sufficient.

Project: Wiring two batteries together

I recently got a Seido extended battery case and I thought I could fit two regular batteries in order use one battery and have another battery there in the unit as a spare. As I thought about this however, why beat the bush?
Why not think of a way to connect the two batteries with a piece of electrical tape and have a cheap ~$6 3000mah battery. Thoughts?
Well..you could always wire the contacts together, that way the contacts on the phone hit both of them at the same time. However, you would have to worry about over powering the phone (too much current to it). So..probably wouldn't be worth it. However, if you have insurance you could always try it...
I actually thought of this before and was about to run to radioshack when I ran into a snag....
I was going to wire them up using a relay so when there was no charge on the original battery it would auto switch to the other. E.g. only one battery connected at a time.
Problems:
1. Phone would shutdown when the relay switched, not too big of an issue as you would just turn phone back on.
2. I think phone would shut off before relay would switch, due to Android turning phone off before battery is truely dead
3. Charging would be an issue due to relay
4. All the relays I found were pretty big
As far as wiring two batties at once to increase capacity. There's only 2 ways to do it:
1. Parralell (Wiring + to + and - to - and one battery entirely to load) which will end up with the same voltage as one battery but twice the amps!
2. Series (wiring - from one battery to load, + from other battery to load, then remaining - and + together) which will double the volts but the amps will be the same!
P.S. I'm not a licensed electrician...
Well ur gonna have to do alot of thinking. What ur gonna have to do is hok up 2 battery's to 1 circuit board otherwise you will blow up the battery's and fry your phone. So be careful and solder right. Do a good job and don't mess it up completely.
Sent from my PC36100 using XDA App
Kept thinking about it and here is the easiest way to do it...and the reasoning why it will work.
1. If you are to do it you will need 2 identical batteries. Same make, model, and age...preferably new. Otherwise one will degrade.
2. Running in parallel WILL double mAh or discharge rate. I didn't think so at first but it will.
3. Since we can't supply the phone with more volts than it can handle we cannot wire the batteries in series.
4. So we must wire them in parallel, this will double batteries mAh, volts will remain equal to one battery, and double the amps.
5. Doubling the amps should not hurt phone as it will only use what it needs. It is bad to have less amps but not more.***
So, according to my original battery specs if I were to wire two together the end result would be:
3000mAh 3.7V @ 2A
To my knowledge this should work fine.
There is only 2 things that should be verified by an electrician - i.e. not me.
***1. I know more amps is OK, but doubling them I am not sure about. The phone SHOULD only draw at 1A regardless.
2. Charging with the batteries connected together should be OK, this is why I said to make sure their identical. But I would still recommend charging them separately as this is where most damage can be caused to batteries.
You would be fine with them in parallel, amperage is a nonissue as amps are pulled not pushed, charging I'm not sure about I don't know how the charging circuit works in these phones.
Ps I am a licensed electrician
If you ever take one of those cheap Chinese 3500 mah batters apart its just two smaller batteries hooked together and wrapped up.
Well that is all any battery is, a groping of cells. And the cells inside of a single battery are paired to match the exact specs the phone requires.
P.S. I actually have another battery on its way in the mail. I had my warranty send me one so I have a spare. If it is identical to my current one, which it should be, I will test this idea out.
Wouldn't it be easier to order an extended battery with the battery cover from eBay for like $7.50 delivered? Or is this something you wanna do just to see if you can? I don't see why anyone would take the risk of blowing up their phone for this.

More or less just to do it, and I have warranty with no down payment so I can get new phone.

Why spend the time and risk damaging your phone?
I can understand the curiosity, as this has crossed my mind before as well, but i figured it simply wasn't worth the time/money/effort

I'm an electrical engineer and this is correct. The circuit (phone) will draw the amperage needed to run regardless of capacity.
This is the same deal if you get a laptop charger. If your laptop takes 12VDC at 5A and you use a 12VDC that is capable of 12A, you won't hurt your laptop, as the laptop will only pull 5A max from the charger. If you use a 14VDC at 5A you will probably fry something on your mainboard.
Similarly, if your phone takes a 5V .5A charger and you use a 5V 1A you don't fry your phone.

samsung sII battery case

Just got it in the mail - had pre-ordered it from Mobile Fun about two weeks ago.
Someone else posted pics already, but couldn't find the thread - here are my own.
Note, the case acts as a battery charger, and starts delivery electricity as soon as you put the phone in. There is no switch on it. I'll have to see in the coming days, but it looks like it's necessary to only put the pack on when you need it.
Things I fear but may be unfounded:
it won't be practical to leave the case on at all times
need an extra charger to charge them seperatly and efficiently
I hope I'm wrong, and hope I can just keep it on at all times, and charge both the battery and phone at the same time using one charger.
Thanks to Eiraku posting in this thread, I was able to find the original thread for this battery pack:
http://forum.xda-developers.com/showthread.php?t=1110441
Mods please feel free to merge subjects.
Here are more pics
Isnt it a bit harmful to always have the battery at 100% charge level and even have trickle charge, they should have implemented a switch or at least some control mechanism to have it start charging only at around 50-80%
I think you're right, and indeed, the case start charging the phone even if the phone's battery is full.
From the manual:
"When not in use, remove your phone from the power pack."
Kinda of a let down. But I'm still happy to have it for my asian trip at the end of the week - electricity will sometimes be a luxury.
The purpose of this case is kinda moot if it does not have a switch and cant be kept in use.
Thanxs for the pics...I ordered this case from expansys a month ago and am still waiting on it to ship. Looks great.
So what is the purpose of this button

There IS no such button. Only the battery tester button (which is useless).
Cost cutting, Samsung? You delayed the battery pack to remove that freaking power toggle?
Personally I can't wait for PowerSkin to come up with something better (OR that urban legend official 2000mah internal extended battery with new cover to come out). But as of rite now, I'll take what I can get.
To OP: thanks for the nice pics. They're much better than mine anyway. And welcome to the club!
There is indeed a button as indicated on the pic you have there, but on mine, it doesn't quite look like that. There is no marking on it or next to it - it's a simple push button which function is to indicate battery level. When you push it, the battery indicator will light up green, blue or red according to its energy level.
The pic you have may be a prototype or maybe a different version other people are going to get?
Without power toggle
I will cancel the order
Guys,
Surely just because there is more power available behind the standard battery, doesn't mean the phone will suddenly start drawing more power from it?. A car doesn't consume more petrol when the tank is full... how would this be any different to putting a ...say 2000 mAH battery (if it becomes available) instead of the original OEM battery??..
More mAH added by the sleeve should give extra run time...
Riz
I'm no electrician, but I like the full tank analogy.
Imagine the tank is full, but let's say I keep pouring fuel in the tank while the engine is running ... kinda of a waste as the extra fuel will spill - not to mention the danger.
So the question here, if the energy or extra energy delivered by the battery isn't being consumed, is it wasted? Is there danger if there is "spillage" in the form of heat? This phone can already get incredibly hot it you use it as a GPS for an extended period of time.
I'm still concerned about what the manual says about removing the pack when unused.
Actually, I have all confidence that this is a "smart" charger, in the sense that it will only top up the internal battery as necessary.
Using it as an "extender", I have no issues getting 3-4h extra on really heavy, constant screen on 3g surfing. It didn't even get hot at all, so power was NOT needlessly drained.
As a "charger", I got from 6% to about 42% from a fully charged extpack. In this config, the case did get quite warm, which indicated that it was quickly expending its reserves to charge the SGS2.
For a 1300-ish mah pack, this is more then consistant performance in my book, from my experinces from owning multiple iPhone 4 batt cases.
Only issue is with the lack of power toggle, there's much less flexibility allowed. You can't choose to keep the extpack as an emergency reserve UNLESS you take it out.
Also, it only takes in 700ma (the Samsung charger is rated at 750) and gives out 650ma, which means that in the event that you are charging a fully depleted extpack and say a 50% power left SGS2, the charging of the extpack will take FOREVER (phone first, then case).
But charging the SGS2 takes forever to begin with, so...
I'm no electrician myself...
But... about the car engine.... there are fuel governor controllers which only allow enough fuel as is needed to enter the combustion chamber...
but.... we talk of batteries... the way electrons work.... my understanding is...
flow of electrons is decided by the potential differnece available for them to travel across.. the higher the potential difference... the more electrons would flow...
So, lets say... the SGS2 has a power consumption of 100 milli-amps (based on whatver the volgtae rating is).... a 100 mah battery would run it for 1 hour... a 500 mah battery would run it for 5 and so on....
Adding a battery in parallel.... would not increase the power consumption from the original spec'd power requirement of 100 milli-amps... it'll just increase the total amperes available to run the device... so.... more ampere-hours available... hence longer hours available to run the phone
Quite simply, it is similar to leaving your phone connected to the charger... I'm sure most of do this every night for the duration of the night....
leave the phone connected to the charger... i.e.
Ars Technica has a good article on batteries. It basically says this thing should have a power button!
http://arstechnica.com/gadgets/news...-is-the-best-way-to-use-an-li-ion-battery.ars
"On the other end of the spectrum, keeping a Li-ion battery fully charged is not good for it either. This isn't because Li-ion batteries can get "overcharged" (something that people used to worry about in The Olden Days of portable computers), but a Li-ion battery that doesn't get used will suffer from capacity loss, meaning that it won't be able to hold as much charge and power your gadgets for as long. Extremely shallow discharges of only a couple percent are also not enough to keep a Li-ion battery in practice, so if you're going to pull the plug, let the battery run down for a little bit. "
I believe that the phone, like the iphone, and most laptops, don't fully throttle their devices on battery. So maybe when it's plugged in it would use more power thinking that it's tethered into the wall. I had that issue with my iPhone 4. I had a battery case for it. The phone itself could last me say, 6 hours on its 1400 mah battery. When I put the 2000 mah battery back on it, before the battery pack died, was only 5 hours. So my phone consumed 2000 mah in 5 hours, while on the internal (smaller battery) it consumed it within 6 hours. Hmm... That's not right. So, then I investigated it and while plugged in the phone went into "performance mode"
Is that at all possible on THIS phone as well? hehe.
I'm not big on the whole battery switch, so, I'm skipping this case. I wrote power skin and let's see if they release one for the SGSII. I'd love it if they did

There's also the fact that a battery directly wired to the device will always perform better per mah vs an externally mounted battery. Heat loss through the external connector, yada yada.
If you're afraid of "performance mode" (which I also think some phones have), just use SetCPU to override it, like I do.
I'm hoping PowerSkin comes up with something soon too - as a case, the ExtPack has really crappy all round protection, especially on the front (getting the SGP Glas protector because of this).
i'd go for the case only without the battery.... it looks quite dangerous...

Battery issue

Dunno how to say it in English but physically my battery is getting bigger, and when on battery low, it gives me the notification and the phone just turns of on the same second.
The battery is starting to be like a balloon and and hardly fits in the phone, can anyone tell me what's happening?
btw, I'm using the stock ROM now.
Your battery is bloated. Congratulations. To fix this, there is only one solution. Change your battery.

Hi, found this on eHow and as automobile electrician dealing sometimes also with batteries i cannot confirm that your battery was bloated just because of playing games an charge phone at same time. Li-Ion cells don't like to be fully discharged. When u charge them before they go out of power is the best you can do to preserve their capacity.
Don't use your phone with silicon case when gaming because it can prevent air ventilation in the phone and cause it to heat up more when placed under heavy load like when playing games.
And now what can contibute to a battery bloatup:
Battery Components
• Most cell phone batteries contain a lithium-ion mixture. Lithium is an alkaline metal, and its ion simply has more electrons than protons. The battery also contains a positive and negative electrode, and when you use the battery, the lithium ions move from one to the other, creating an electric charge. Under normal circumstances, the lithium ions can continue to absorb and dissipate energy. However, if you expose the battery to certain conditions, its chemistry can change, causing undesirable effects.
Water Damage
• Your cell phone battery is extremely sensitive to water. The plastic casing provides some protection; however, if you expose the metal electrodes to water, they can corrode and become ineffective. Water leaking into the batteries case can cause it to appear bloated. Discard such a battery immediately because the lithium solvent can be harmful if you come into contact with it. If the phone has been submerged in water, this is usually enough to cause water damage to the battery if there is not a tight seal between the battery and the phone.
Heat Damage
• The lithium solvent that carries the charge from electrode to electrode is extremely sensitive to heat. If you expose the phone to temperatures that considerably exceed 77 degrees Fahrenheit, the battery may lose its ability to hold a charge over time. This is considered normal. However, if you consistently expose it to higher temperatures, then you can cause the lithium-ion mixture to rupture the cell, which can cause the battery to appear bloated. Most lithium-ion batteries contain fail-safes that prevent them from operating in extreme temperatures, but there is no guarantee that these will work in every case.
Prevention
• Prevent damage of this sort from occurring by not exposing your phone to extreme temperatures and unsafe environments. For example, do not bring your mobile phone near pools or inside of saunas. On hot summer days, keep the phone and other electronics out of direct sunlight.

But I can confirm this. I´m having actually here 4 batteries for the SGW and one of them is bloated due to heavy usage while charging the battery. This battery was my best battery but now it´s just a paperweight. It´s still working well though it´s bloated, but I´m not going to risk anything.
You can´t simply compare a car with its lead battery to this device, because in the car the battery is just needed to start the car. Once the engine is running the battery is not needed as the generator is producing enough electricity for the entire car and to charge the not needed battery.
You can even remove the lead battery completely and just connect the car to a powerfull enough source to get it started. Onec its running, you can remove the source too and it will continue to run.
With the SGW and its LI-Ion battery things are a bit different. You for example can´t simply plug in the charger and turn the device on without the battery. The battery is still neeeded to power on the device for two reasons. First is the charger might be not strong enough to offer enough power but the obvious one is, the circuit inside the phone reduces the charging current to a max. level and the voltage to be 4.2V max. It acts like a constant current and constant voltage source where the preset max limits can´t be exeeded. The real charging current and voltage are depending to the charging level and the battery resistance, but will never exeed the max limits in a proper working circuit.
Additionally this circuit is feeding the battery directly, so the current is floating first into the battery and then the battery is feeding the entire device. So at heavy usage the power offered by the circuit will be not enough to be simply passed to the device and so the battery will be stressed twice, as it´s charging and discharging at the same time.
This is still a simplyfied explanation to what is really going on, but explains a little bit why you can´t compare a car with it´s battery to this device.
Also, the batteries for the SGW do not offer it´s own protection circuit. The only circuit that protects the battery is build in into the phone.
So the best advice that can be given here is to avoid heavy usage while the battery is being charged. Better charge it first, use it then and recharge when not in use.

I´m not sure where you digged this out, but this is simply not the full truth. In neutral stage each element is having as much electrons as much protons it has. Ions are either having temporaly more or less electrons. They can be ionized positive or negative.
In a normal Li-Ion battery it´s the anode that consists of lithium and is having positive lithium ions, so less electrons than protons.
In a lead battery both, the anode and the cathode consist of lead. One is positive ionized and the other one negative.

Sorry if it souded as i would compare a Li-Ion to a lead battery. I was actually not doing that. By that i meant that i understand somewhat of batteries. I've learned about batteries (how different types work) back in school. All Li-Ion based batteries have their own protecting circuit. It is not depending on the phone. This circuit built in every Li-Ion based battery prevents it from beeing overcharged, wich would result in the battery exploding. It also gives the phone a limited feedback on battery charge status, and perhaps somewhat potecting the battery to be fully drained wich would result in irreversible damage to the cells. I agree with you that it is better to charge when not using them, but in real life this is not easy to do when you (by what cause ever) want or have to use your device. I am not a gamer so i am not using my phone that way.
Since i am using my phone lots of times plugged on a charger, making phonecalls and doing other stuff like email, surfing the web, watching videos and so on, and never get close to that issue (battery is almost 2 years old) i still don't think that that would be the biggest problem.
On hot days is it not recommended to use our devices with heavy loads, ofcourse you could climb into the fridge (may not be a problem then), and it is also advised to avoid humidity. That's all i know for now, that it would contribute to a bloated battery.

No problem, I´m just trying to clarify this
but with this I have to disagree

All Li-Ion based batteries have their own protecting circuit. It is not depending on the phone. This circuit built in every Li-Ion based battery prevents it from beeing overcharged, wich would result in the battery exploding. It also gives the phone a limited feedback on battery charge status, and perhaps somewhat potecting the battery to be fully drained wich would result in irreversible damage to the cells

Not all Li-Ion batteries have their own protection ciurcuit. Only the protected ones. Do a search on google about protected and not protected Li-Ion batteries.
In cellphones most batteries are not protected ones because of the circuit taking to much space and so incrasing the battery size a lot. Therefore the protection circuit gets moved into the phone but the battery itself is not protected at all. In most batteries the feedback you will only get is the temperature. It´s mostly a simple thermistor either being somwhere close to the battery or inside the battery. The rest is calculated by knowing the capacity and monitoring the voltage and current drain.
So the only circuit you will find in not protected batteries is the one for reading the thermistor, if there is one build in. But this circuit will not protect the battery against a short circuit.
Just to not confuse about this. There are of course protected batteries for cellphones as long the circuit can fit into the part where the connections are.
But the truth is this circuit can fail to disconnect the battery from a short circuit and there are even batteries with fake protection. So there is a pcb with a circuit, but this is just fake and doing nothing.
However regarding this discussion about bloated batteries it doesn´t matter the battery has a protection circuit or not. The protection circuit only disconnects the battery if a short circuit occurs or the battery voltage drops below 3V.
Buy a new battery.

Note7 Battery SWAP MOD? Note5 / S6 / S7E Battery etc ?

So as it seems the underlying issue was all in these batteries of note7 and the aggressive design of the phone chassis itself - leaving little to no gaps for battery, probably not enough space for battery front and back either so batteries easily got squashed inside of the super-slim factor phone design chassis while wearing phone in tight pocket like situations and due to the fragile nature of the battery it just got affected, damaged and caught on fire like explained in latest samsung reports.
Here is the deal, I will get equivalent original samsung battery from S7Edge model etc, same 3600mAh capacity (providing the thickness is same or less than that of Note7) and with necessary modification (if applicable) to the battery terminal flex connector so it clips right in to the Note7 PCB just like original Note7 battery did, I think this should be excellent workaround for dangerous Note7 batteries!
I of course would try to perform various tests before final assembly of the phone with new battery mod in it, such as full discharge and recharge, also recharge while heavily loading phone with benchmarks, and also attempt multiple fast charging routines monitor how phone behaves with the new battery, that is - all these tests are to be done on phone fully disassembled in the worst case scenario if phone battery still would get caught on fire during the testing I would at least salvage the phone from disaster that otherwise would be inevitable when testing phone fully assembled.
Your thoughts?
I would say you should give it a go. But isn't the S7 battery bigger ? How about trying to go with the S7 non edge battery instead ? Plus I thought that some battery were not soldered properly and made a short circuit to happen ?
Source I read : https://www.cnet.com/news/samsung-galaxy-note-7-return-exchange-faq/
Im yet to find out about the battery dimensions/size. while s7edge appears ~1mm thinner to my observation makes me think battery design should be similar or lesser in thickness and I really expect it to be no taller/wider but that is to be confirmed later when I take it apart(if it comes to that).
If batteries do fit, all I need to do is to unwrap the shield of the note7 battery where PCB is soldered to +/- terminals and replace battery connection pcb the same way back to s7e battery.
I think s7e battery would be the best candidate as for 3600mah capacity vs 3500mah note7 capacity, even if phone some way tries to charge this battery further than 3500mah as per physical capacity of the battery it should be "safe" I think.
Where if the battery installed would be ~3000mah etc, note7 battery terminal PCB chip would probably try to achieve 3500mah capacity and charge may again result in innevitable fatality, that is unless note7 battery pcb chip registers battery capacity 3000mah as wear and tear and adopts to charge only to 3000mah without actually overcharging it.
Had some hobby experience playing with iphone 4 4s 5s batteries in the past where I would swap around pcbs with batteries and phone would work, not ideal because I didnt pay much attention which went where but it did work to great extent.
I too see that the defects ratio was not definite and more so it was one in many many thousands that had bad soldering or manufacturing practice etc missing protective layers and so on, as I observe my note7 battery is always very cold never hot even cooler than that of s7 edge so I think analogy goes to be correct, but still I rather not take much chance with it if you know where Im going with this - "WHAT IF..."

Well, whatsup with that straight "face to the wall" so well thought trough pessimistic comment?
Do you not have life to live meantime?
It seems as if the flex cables are different and the note 7 battery is narrower.
I'm disappointed there hasn't been an aftermarket manufacturer that has created a "safe" battery replacement yet.
I'm using a Verizon Note 7 that I reflashed with AT&T firmware. Since the IMEI is not an AT&T IMEI, I haven't had to worry about "green battery" or "killswitch" updates coming to the phone. Still worried daily that my house will burn down or something, however.
I think no company will provide an aftermarket battery because the market is very small. That eventually would happen if Samsung refurbished all Note7's and reintroduced them in the market. Mine (have 2) are working flawlessly without any issues

Im not certain about sizes yet, it could be alot due to optical ilusion, as s7e and n7 are little different layout, etc - battery in the s7e is seated little further to the left (meaning more toward the center of the phone) and the camera on s7e at least to me from the first glance when compared to n7 looks more further to the right side which creates illusion of s7 battery to be wider because of its positioning. I may be completely wrong, just wanted to throw that in there though.
Also, battery from note4, S5 can potentially be used too, of course its core would need to be stripped and de-soldered from the old PCB and after that you have a naked battery pack that is still permanently safely sealed with two (positive and negative) terminals exposed ready for soldering with original note7 battery PCB and connection, providing we get enough room inside battery compartment. it all can be utilized, and even more, maybe note5, maybe s6 s6edge s6edge+ s7 and other similar sized samsung batteries of recent production years have similar measures that will make it a good potential donor? I'd say even if one can find battery of similar but not larger in size and capacity battery from any other manufacturer it should also work by the same methods of DIY, of course obviously acknowledging that the use of quick/fast-charge can be detrimental suicidal step in a way of charging the phone after any such DIY, even if it was samsung approved battery, fast charge is a fast-lane of premature battery wear/overheat and failure, such as explosions.
Here is my observations, I own few of these Note7. I have never ever once used fast charging on them knowing what it does and how it physically affects batteries, never ever had I used it on my note5 s6 s6e or s7e, I rather have my phone charge longer rather than let battery prematurely wear out sooner, and nobody knows what if S6 S7 batteries undergo the same quality testing like note7 batteries did and it was just a great matter of luck to a slight degree that not so many s6 s7's had exploded in the past due to quick charge technology used. Of course, alot of what I said is speculation, but just take that for a minute and let it sink in, think about it. Its certain - not everything that ever happens is publicized.
Ok, according to my research (call it bro-science) as it was internet based on official reported measurements of devices, I picked some stripped down samsung phones (notes and S series), adjusted these pics to represent real manufacturer reported dimensions in photoshop and measured batteries in the pictures. So far I can give rough estimates and the best to my knowledge these measures may not represent exact measures of the batteries but actual measures should be less or equal than what I have figured out. Only thing left to question is the thickness of the batteries:
We have here a patient, in a name of: Note7, this battery measures 99mm x 38.5mm
Other models I have looked at were:
S7edge 96mm x 41mm ( @MrBaltazar > you were correct regarding battery size there, its too wide )
S7 88mm x 37.5mm (looks like ideal candidate for now, especially providing extra headroom for DIY work on the top of the battery which may not come out as neat as from manufacturer)
S6 99.5mm x 46mm (too tall & too wide)
Note5 108mm x 42mm (too tall & too wide)
Note4 93mm x 39mm x 5.5mm(also seems like an ideal candidate plus its 220mah more in capacity vs S7 3000mah battery)
S7 Active 91mm x 40mm (this would be interesting @ 4000mAh ... I just am almost certain - thickness of this battery got to be greater than note7 or note4/s7 candidate battery... a strong guess)
I feel note4 may be real good choice if S7 battery thickness is more than that of Note7, and note4 battery turns out to be slimmer or the same thickness after being stripped as Note7 battery ... especially after removing the top plastic trim that holds gold plated battery terminals with battery pcb and unwrapping first layer of label with NFC antena, that should shave off additional ~0.2-0.5mm from the whole 5.5mm note4 battery thickness.
So thats that, some food for thought
Alright first off,
HOLY ****ING ****
Second off,
That's amazing
Third off,
**** you ;P
Keep up the good work mate! If you can find a system you can replicate let me know, I would LOVE to try it.
Im sure it will all work well, keep an eye out here, this actually drives me somewhat to do this. Most interesting is testing under load once all is done.
I was thinking more, and I believe S7 3000mAh battery is the best choice regardless of anything (unless S7 Active battery magically fits just the same, but its unlikely given its huge capacity it must be much thicker, but I am not sure 100% yet anyway). S7 and Note7 is of the same period/same production line, so if anything it should work the best, even with quick/fast charge when needed, as I thought today it still would be a very good feature to use if one is stuck in an emergency situation such as airport and needs a quick sufficient charge in short time - if fast charge works well - its there to use, otherwise I would still be against using it every-time, for longevity of course.
another interesting trick would be to remove Note7 battery and have it X-Rayed to see if any dangers are underlying like those explained by samsung, should be visible under high-res x-ray imaging, but I dont have access to that(yet) so I will still keep the note7 battery cell for a while until maybe I get access to such equipment.

Sounds like the Note 4 battery might be the ticket. I'd be willing to try this out if I knew how to attach the note 7 flex cable to the note 4 battery, as well as disassemble both batteries.

I am actually almost tempted to order a s7 battery and see if the connection is the same on the note 7 PCB. Then it's just a matter of bending the flex cable into place
Connectors all look identical for S6 Note5 S7 S7E , what worries me most I think the most is its the way pinouts can vary on them model to model, as I remember there's not only Positive/negative terminals , look here:
other connections are also important, and most important that it is not going to get connected in reverse which I dont want to even try, thats too precious loss if I fry anything on note7 pcb, try go and get another one of those note7 pcb's nowadays ahaha, let alone note7's !
So, all in all we can try and measure terminal voltages on both Note7 vs S7 and compare how it looks on multimeter, then try position it accordingly and expect it to be straight fit, then if all works well and flex is actually long enough - solution is found, no need anything to solder I suppose just plug in, bend flex a lil bit where necesary, making sure no sharp edges are exposed to the bent flex, no excessive pressure applied on bent flex cable before/after assembly, and for most part that the battery is right thickness and not squished in there, then its all green-lights and good to go, but just by the visuals it looks that note 7 has somewhat longer flex, and oposite facing angle, look here:
S7:
Note7:
I did not realize it would be this difficult to find authentic original non-replica s7 battery... lots places sell those but if one has half functioning brain its clear as day these are non-original... However, I did find some note4 original in samsung retail packaging and all papers batteries, which I think rather go with, which is almost local too vs. importing another second best from China/Hong Kong... so that's that... My only hopes in buying note4 battery, if its truly original and new unused not charged unabused piece is that if it will still actually hold 3000+ mah capacity off the shelf ... hope it will. I mean after all it would be dormant for 2~3 years or more, and batteries do get old and sometimes just prematurely die also...
Will keep you posted
Night
Updates...
So far I was very unlucky sourcing S7 battery which is my personal preference option due to this battery being most "up to date" tech variant available that should logically fit vs. the second best choice - a Note4 battery...
Also my donor Note7 is due in tomorrow as best case scenario, or latest Monday-Tuesday the 19'th-20'th of February, and I just dont feel like burning 30bucks on battery that probably does not fit by its thickness... (talking about note4 battery) , so I really want to take apart this note7 first and inspect the thickness of its original battery and the depth of the phone. What I mean in detail by that - please review this in-depth detailed report:
https://www.instrumental.ai/blog/2016/12/beyond-the-teardown-galaxy-note-7
^^^ That is allegedly a note7 illustrated right there, this gives me hopes as if I stripped plastic and NFC chip from note4 battery I should end up with just about 5mm of thickness of the naked without NCF chip and w/o labels battery. However, I need to look harder about the S7 battery thickness as my eyesight would be strongly concentrated toward that if it was of the same thickness or even better if it was just under 5mm, but I am not sure...
I also contemplated maybe even retrofitting apple iphone 6/6s or 7 battery providing it fits by its dimension and voltage measures (yea just pulled it from thin air havent measured or researched yet) , but at least talking about voltages should be bout right and capacity may be close to that of S7...
Otherwise I was even thinking removing NFC/Wireless charging mechanisms from the enclosure so the excess pressure from battery wear and tear does not build up on either old original or new replacement retrofit batteries, give or take there has to be ~10% headroom for battery expansion which was really not thought trough in note7's (or if it was there was general battery design fault that was underestimated and exaggerated expectations from engineers who designed battery had failed them prematurely...)
I have meantime located S6 battery which is way too big and it by no means going to be fitted there but I have another few tests in mind until I get my properly fitting battery alternative, just to rule out some questions and variables...
I think Chinese market fellows are up to some news regards note 7 because just lately I have noticed increase spike of note 7 cases and accessories at least on ebay, it just spiked my curiosity, what are the plans of samsung for the remaining 3+million note7's that they got back from the recall, are they by slight chance gonna push Note7S with note8 and S8 release? what are the chances of that happening?
Also I was deeply considering how would note4 battery be of a worse technology build vs S7 battery, knowing everyone who I know had note4 in the past almost every single one of them batteries had expended and died out rather soon within first year or so... I am just very cautious about this happening prematurely while retrofitted in note7 ... where as with S7 as many people I know using them and it has been about a year now of heavy use and abuse including those using quick-charge, batteries still perform ok and not swelling which is more promising when compared to note4 battery.
As lucky as I can get just by doing online hunt, I found one seller on aliexpress selling copy replacement batteries where he claims battery measurements to be ~88mm x 40mm x 5mm, and here we are talking about non original battery that is rated @ 3300mah as per sellers web page , out of which I feel it is reasonable to believe that it holds quality ~2000mah capacity knowing how all these generic batteries are made... it is real hard to find genuine battery, unless if I want to wait 60 days, I can order from China... hard hard decision on waiting vs the availability. I really am leaning forward just straight S7 battery swap with best hopes of longevity , but the quest now is to get exact measurements and fast delivery.
PS: Anybody reading this has new original battery for S7 (SM-G930 / G9300)who can ship it over to me or measure it precisely X * Y * Z ?
Thanks
I Tried Note 5 battery. Its bigger in terms of Length and width. As mentioned before flex cable is different and male/female end of connectors have been interchanged.
Out of desperation disassembled old battery and took the battery circuit out. Soldered Nokia BL-4C 3.7 V 840mah battery. Voltage of battery at full charge ~4.1V. Charging stops at 100%. I was thinking of installing something like old rom to limit charge to 60%. I will be installing wireless charging battery for the battery backup.
Its quite fun to play with it.

Nice post, looks like you did not strip nokia battery from the nokia battery charging PCB so it literally goes two ways. I may be wrong but I believe I am not, when battery wears out on original samsung battery combination, lets say samsung s7 battery was used and abused and from 3000mah drops to ~1700mah real usable capacity, the charging chip adjusts accordingly to the current usable capacity and stops charging when receives signaling from the battery that it no longer increases in the charge capacity. Hope Im putting it out right so you can understand, I believe if you use note7 charging pcb chip on stripped nokia 800mah battery it should literally accept 800mah as total max capacity and record this "100% equivalent" memory record in to its circuit (dont know if its one way memory write though , because as if you were to add 3000mah s7 battery on the later date, the N7 battery charging pcb chip may decide only charge it to 800mah due to previous record of capacity created when 800mah battery was used...)
Its complicated I know... but thats what I would do. Otherwise, two nokia batteries if stripped could be coupled parallel (if it fits well) and you therefore have 1600mah battery) which is rather usable for at least ~ half a day off the power cable
I was also thinking about note7 wireless battery charger mod, I dont know whats inside of that battery back pack, but if there is enough space to store two S7 or S7edge batteries, that would be amazing DIY mod that would deliver ~9000-10000mah of raw juice coupled with S7 battery already installed in the N7 frame.
For most I hope tha note7 battery charging chip does not have memory recording feature on its own, so we can play with random batteries for as long as we find one working the best, as otherwise if it does have such effect - its sad news, as once you install less than 3000mah S7 battery for testing etc, you can never use 3000mah brand new batery to its full capacity, but I am only speculating here for the most part untill its tried.
While on this note - would you have another of the same type nokia battery to connect in parallel (doubling the capacity) to see if it still charges to 100% on indicator and last ~twice as long after this mod?
PS: I think time to time n7 backpack battery cases appear online on ebay for lots cheaper, worth a search there too
Also, the charging indicator @100% is fine and well, and setting limitation of charge to 60% in settings would result in 60% of currently measured capacity which I believe is pretty pointless as that was the aim of samsung safety/prevention methods, knowing batteries usually failed while in higher charge state - they tend to swell more and tight fitment inside the n7 prevents expansion therefore battery will be softly pushing against itself while theres a risk of failure at that shorting within itself due to built up inner pressure, thats why the limiting to 80% then 60% then 30% was put in place so batteries does not reach high charge state there fore does not expand as much within itself and the risks are greatly reduced, that's how I understand samsungs point of view on the issue.
Let me know what do you think

Hey I was just typing a reply to this thread and have seen you reply to it before I clicked [Submit Reply] ...
Ok, so Im in a "triangle" situation here right now... yes I had more of them note7 on hand but now... I have only two coral blue note 7's, one is new and unused but still it is unsealed box unmodified/unupdated unit which works perfect and charges to a 100% battery etc which I intend to keep this way for later on selling it for a profit probably to some enthusiast collectioner guy...and another coral blue note7 is as good as new but it is used for few weeks by the first owner and it had this deadly update from samsung that prevented it from charging, so I have fixed this and now it is charging while still on its latest firmware and I am willing to play a little more with its firmware and so on until I decide to sell it too ... yeah I cant explain, I just enjoy reaching for some "goals", hitting them hard and then letting them go for someone else to enjoy while myself moving on, maybe weird, I know., but stay with me here for a moment. So I was thinking long and hard, and I am unable to justify splitting open my last firmware-fixed note7 that I was so anticipating on doing so ... that waterproof seal from factory means alot to me, I'd rather keep it on the phone for as long as I can, unless that would be inevitable, as I originally imagined the last note7 unit with disabled battery charging would require me to split it open to do at least battery charging up outside the phone just to get it ON so I could work on it trying to patch firmware and do some battery experiments further while Im at it, but as you may know I managed to fix it without opening it... and I few days ago (again...) I ordered myself another one of these bad boys Note7's, but this time its for real guys, its a cheap live demo unit (LDU), it should have no IMEI/no GSM radio chip and otherwise to be identical to retail units, so this is the model I will be stripping apart, most definitely, promise. Meanwhile I am really seriously thinking about learning on rom modding so I can build at least one or few fresh Note7 rom's for folks that are still out there holding on tight and giving all the love and care for their old note7's. The only one real reason is holding me back from keeping and using one of two note7 straight away and modifying it for self use is that I cannot get my hands on any dual sim note7 model (SM-N9300 or SM-N930FD), which I adore to death, literally... as my daily driver of a phone is S7edgde DUOS at the moment and it is a life saver not needing me to carry two phones everywhere I go, and any of note7's I had would make me do just that, use 2nd phone which is really not ideal at all... however dilemma in my mind goes to expect me to finally modify and use one of the two blue note7's if I will not be able to sell it for minimal no-loss profit, but for now I do not the plan on using any of them for daily use, hence my reasoning on waiting till I get Note7 LDU some time next week and give it all my tech-modifying love so I can break the IP68 water sealed back loose, probably crack it or scratch it and not be bothered about the rough love and abuse because Im about to give it, as this LDU has no such value as any of other retail units that I have... hope you's understand where Im coming from and are patient enough not to cross me over yet and wait a little more for my experiments on battery mods.
On another thought, since samsung-pay will not work and I am not sure if android pay will have any use with such heavily modified note7, I was really thinking taking out NFC/Wireless charging modules from the inside of the back of note7 to get more headroom for battery swap, plus if opportunity allows, I may as well split the chassis from the LCD screen later (if its feasible option) and measure the firewall thickness between the amoled screen and battery, see how much more I could machine off of that firewall while keeping some minimal amount of it still there for screen protection purposes, just a thought in an open wild triggered by the last samsung report regarding refurbed note7's which will receive thicker chassis, which may be ~2mm extra in thickness etc...

Is this Battery Case Worth Buying?

Hi guys.. I'm thinking about buying this battery case for the mate 20X. It says it has a battery capacity of 6000 mah. Does this mean that this capacity is separate from the 5000 mah the phone has, so that I get a combined 11000 mah?
Has anyone here bought it? Is it worth buying?

Just some helpful advice from a recovered extended battery case addict. In the early days when phones didn't have quick charge and we're about 25-50% smaller, I always bought my phones based on the support of manufacturers making extended battery cases for it. As the phone market matured, batteries became bigger and locked in, I noticed that my power consumption was less likely to hit the max of the stock battery. The weights of the phones increased as well and I noticed a chronic pain on my pinky. This combined with the fact that the extended battery cases didn't have quick charge, rapid charge, super charge, it whatever "special" charge came with the phone, as well as a key missing feature of charge passthrough, caused me to drop the extended battery madness. I expect you to come to this conclusion on your own, because like me, you won't be convinced of extended battery cases being a bad joke until you see it for yourself. Make sure there is a good return policy.

Hi techronico,
Appreciate the reply. As far as quick charge goes that will damage the battery in the case the same way it can damage the battery in the phone. This is why I have a slow charger to charge my phone healthily instead of risking permanently frying the phone's battery which will shorten its life. I'm no fan of quick charge.
Regarding pass-through the seller confirms that the power case is equipped with heat, overpower and temp protections. What do you think?
Just to be sure the power case doesnt degrade the phone battery do you think its best to charge the phone case and phone separately and not connected together?
Looking forward to your reply.
I would never spend money on anything like that since I can get 2 days on a single charge on my 20X. All the new phones now use LiPo batteries (the same cell type used in Tesla cars) and have no problems with quick charging and don't exhibit memory as it's predecessor battery types used to have.

Hi ben,
I'm not talking about quick charging. I love slow charging.
Anyway I get 3 days from my 20X. The problem is when I have 30% left it starts to drain like crazy. Thats the reason for wanting the battery case.
Did you get the battery case in the end? They are available very cheaply now from Aliexpress. I don't really have a problem with battery life but am thinking it might be a nice gadget to have
