[Q] Battery dying, should I buy an external charger? - Samsung Galaxy Nexus

Bought my phone on Black Friday 2012, bought a spare battery about a year later, and now both batteries are virtually gone.
The (newer) battery has bloated significantly and is now officially retired. AFAICT it was completely original from Samsung, with NFC. The older one lets the phone go on only if it is charging, and then holds for maybe 3 hours of no or little usage.
I admit, I haven't followed the advice of keeping the battery between 20 - 80% charge, and other maintenance, so I'm willing to believe this is what was expected under the circumstances. Is it?
AFAIK there is no app that can display the true capacity of the battery. Is there by any chance a testing app that measures how long it takes to drain under a specified controlled workload, and hence find out, somewhat accurately, the capacity currently?
Now I wish to buy 2 external batteries + a external mains charger for it, and actually do some maintenance on it for its life. Is that advisable, or should I only charge a battery inside the phone?

Bump... no one?

How to manage two batteries?

I've used my Galaxy Nexus for six months without using a secondary battery. At first I bought the extended battery with extended battery cover, but not only did that make my phone too 'thick', it also seemed that Galaxy Nexus is unable to know which battery is being used, so the battery life seemed incorrect when using the extended battery.
I think this has something to do with the battery info memory that the phone stores.
So I ended up buying a second battery, a replacement battery that is exactly the same as the one I originally have in my Nexus.
But since batteries are still different and are bound to perform differently, I wonder how to manage it correctly? Do I always have to drain the phone completely empty before switching batteries and charging the battery with a separate charging dock? I am worried that the phone considers performance of my battery A as the same as battery B, thus in time ending up with lesser battery life on both due to the confusion.
Are there any tips I should know? I need to use replacement batteries since at times I'm on an extended trips where I might not have the ability to charge the phone, but need to use the phone one way or another.
Thanks!
Ah..... I bought some batteries from Amazon. Cheap, like 20 bucks. They are charged, in my bag, if I run out of juice, I switch and start charging the other one. I still have a 3rd that I've never had to use. Hell I hardly use the 2nd one.
All the other stuff you mentioned, I guess I just don't care about all that. I just know they can hold a charge for quite a while. And that helps me when I need it.

These are Li-ion batteries.. DO NOT DRAIN THEM ALL THE WAY DOWN!
**This shortens the life of the battery**
It is better to charge them whenever you feel like it - these batteries and really almost all phone / laptop batteries these days prefers to be charged in shorter cycles and they also do not need to be charged all the way either - IE lithium ion batteries do not have a memory and do not need to be drained and charged fully.
These ideas come for the ancient Ni-Cad batteries famous in AA rechargeable and cordless phone and really old phones / laptops..
Chances are if your device is less than 5 years old it has Li-Ion batteries and the old school thought will actually shorten the battery life
Battery life meaning the amount of power it holds and the number of charge cycles...

You CAN drain them down, as much as the phone allows you. Only deep discharge will harm/kill them.

You cannot drain battery completely empty with a phone. Phone itself will not allow that to happen. Well, it is technically possible, but you need to do a lot more than just drain it until phone shuts down to make it happen.
My problem is that the phone stores information about battery. But if I use two different batteries (despite being the same type and capacity), during battery switches it will not know the battery life of the second battery and can be wrong (as it guesses it based on first battery). People usually delete batterystats file to reset this information, but that sounds pointless to do after every battery switch.
I guess I'll just discharge one battery to about 50% and then store it for just-in-case purposes.

Just a quick link to help out, if you want more info you'll have to Google it yourself
You can use 2 different size batteries without decreasing their usable life per charge.

Review of Intocircuit® Power Castle 12000mAh Portable Dual-Port External Battery Pack

This is an amazing battery with a great build quality and performance that is just out of the park!
In the box, you get the battery itself, a micro USB cable, a really nice carrying pouch, a HISCARD warranty card, and an instruction manual.
First Impressions: This is so nice! It feels so smooth and premium in your hands. The orange parts of the battery finish it off very nicely. Pressing the button to illuminate the battery percentage blew me away. It is a really bright blue LED indicator that grows on you immediately. Using it was a breeze. I simply used the supplied cable and plugged it into the battery. I then plugged that into my phone, and it was charging. I didn’t even have to press the button, it detected that the device was connected automatically.
After using this for a while, I can safely say that this is downright a great battery! It does exactly as it promises and this is a product you have to have in this day and age if you don’t already. I was able to charge up my Samsung Galaxy S3 in no time with the 2.1A port. If you ever find yourself with no place to plug in your phone and/or if your phone dies, this will be your savior. This battery is just that good, I don’t know what else to say. Intocircuit got the design, build, performance, and feeling just right! It’s a perfect battery, and I haven’t experienced any conflicts with it.
I would recommend this to anybody who is in the market for a well-priced battery that has a great build quality, feels good, and works well.
Overall, this is a great product and I highly recommend it. One of my favorite things about this battery isn’t just the metal build, but also the carrying pouch. It is a great accessory that makes this product perfect!
I was provided a unit for testing purposes and I promised to provide a completely honest and fair review.
Unfortunately, I cannot post the link to this product on Amazon because posting commercial links is forbidden, but you can find it on Amazon by searching for the product's name that is in the title of this thread. Thanks!
Just ordered one of these and am waiting for it to arrive. It's looks great and seems a bit slimmer than last year's model while having a larger capacity.
Yes, last year model (11,200 mAh) was not good. Very poor efficiency where you loose over 40% of capacity after conversion and also a poor standby time where I suspect LED display was draining the battery at high rate.
@Mon431, charge it up to 100% and set it aside for a week, and come back with a reading of remaining battery without using it to charger anything. See if it drains in standby. Also, you can try how many times you can charge a phone or a tablet with a known battery capacity off this 12000 mAh battery to see the actual capacity.

Good idea @vectron, I've started the standby experiment like you mentioned. It's been one day and so far, it is still at 100%.

I decided to do your experiment for an extra week, just to see how it would hold up. After two weeks of not using the battery after fully charging it, the battery is still at 100%! This battery definitely has a great standby time.

Phone abruptly dies under 20% battery

Phone totally goes black/dies when battery is 21% down to 10%. does this just mean the battery I have is bad? What replacement battery is best? I've read Anker makes a good set with charger. Thanks.
Samsung SDI batteries are the only batteries I've known to do this. When screen goes black, that should be a shutdown. Do you plug in your charger at that time? Mine actually actually showed 0%.
It's inconvenient for a battery to shutdown unexpectedly, while showing capacity remaining. I always replace Samsung OEM batteries with another brand. I found one that I liked so l went to Amazon and bought a second plus external charger from same brand. If looking at another alternative, just search MPJ and read the reviews. The battery and wall charger were on sale last week, maybe still.
If you're considering upgrading to sealed battery in unibody phone, you should consider the care required for such a phone to get battery to last. Sealed batteries are actually very similar in capability and ratings; no leap in tech but apparent shortcoming evident in Note7 embarrassment. Fast charging produces heat and steals life from battery's endurance down the road. Studies have shown since lithium batteries have no memory that you're actually prolonging the battery by slow charging without load or minimum load and bump charging rather than cycling battery to near 0% then back to 100%. Manufacturers don't tell you that because they prefer you wear your battery down in less than a year's time and consider another phone purchase.
Maybe Samsung would be better off today if consumers were more aware of how to prolong lithium batteries?
If you want your battery to last two years, bump charge it after 25% used as much as possible; it shouldn't even matter if you bump charge it 3x per day. Avoid fast charging and heat cycles. IOW, try not to use it while charging; the cycles should be short anyway.
Or, if you prefer to abuse a removable battery like the Note 4 and care less, pay about $15 and just replace the battery every year. 500 full cycles is all these batteries are currently rated for due to increased degradation with abuse. Mini cycles allows more of those cycles without degradation but you'll still have capacity when you need it to last a long day without charging.

Try this, if you are rooted and have recovery wipe dalvik cache and cache. Power off phone and pull battery for like 5-10min. Hold the power button (with battery out) for like 1-2min. After letting battery sit out for 5-10min reboot and see what happens. If same instances occur. Your battery is dead just purchase a new one! Anker recommended!

You're welcome.
Bump charging is partially charging before battery gets low. An example would be running the battery down 25% and charging without overcharging it.

Had the same issue, bought a new Anker and issues resolved, the stock Samsung sucks!
I'm just glad there's a way to replace it that'll mean this phone can last a long time if I'm careful with it.
Yeah it must be these batteries. My mom has the Note 4 as well and hers does the same thing. As does mine

Yes the stock Samsung batteries are horrible. They don't last very long then they start misrepresenting the battery statistics to the OS so you get the shutdowns at 20 or so %. I switched to a twenty$ Anker I found on Amazon over 6 months ago and never had the issue occur again. Even thy sprint techs will tell you if you ask them outright!

Couple Battery Questions

Got 2 new batteries and I want to keep them for a while, so I have a few questions:
1. Is the OEM fast-charge charger and cable okay to use every day, or will it degrade the battery faster than a slower/regular speed charger/cable?
2. Since I have 2 batteries now, which is the best way to charge them both up? charge 1 in the phone, then swap and charge the other in the phone? Or buy a battery charger (and if so, which one)?
3. Any other helps regarding the chargers and/or cables?​Thank you for your help.
Faster charging will always generate more heat and put more stress on the battery, so slower charging would be better for a battery's lifespan, but I don't think you'll see a huge difference within two years.
By far the fastest way to keep going is having the second battery charged in an external battery charger and then swap when the other battery gets low, followed by charging the low battery in the external charger. Doing it this way also puts the least wear-and-tear on the phone's charging port since you'll rarely use it. I use LG's OEM external battery charging cradle (BCK-5200), but it may be hard to find nowadays. There's currently a used one up for sale in an auction by an American seller on eBay, and there are new ones from a South Korean seller for a higher fixed price. I wouldn't pay more than $25 for one. As for charging time, for me, it takes about 4 hours to charge my MaxxxJuice 4100 mAh batteries from ~5–10% to full. External chargers do not fast-charge, so you'll never put too much stress on the battery that way. Of course, swapping may not be for everyone as it may be inconvenient to take a case off and put it back on.
Unlike the older microUSB cables, bad USB Type-C cables that are not built to certain specifications can draw higher currents and destroy the devices they are charging. A few years ago, a Google engineer reviewed lots of USB-C cables on Amazon to give his view on those. If you need a third-party cable, make sure you get one from a reputable source with good reviews. My preferred USB cable is Anker's Powerline+ due to their extra strength/thickness, and I don't need much flexibility/twistability in my cables. Also, I like how the USB-C end connector is made of one single piece where you don't see any connecting lines around the middle (you can see an example here).
Other thoughts:
As long as there is a supply of extra batteries around and you can afford to buy them when the time comes, then you shouldn't worry much about how you charge your phone. In my opinion, that is one of the main selling points of having a hand-removable battery. I imagine a paranoid person on a phone with a sealed battery would be trying to keep the battery level between 40 and 80% at all times. So really, the only thing to worry about is having a decent USB-C cable and making sure the phone's charging port is clean and not worn out.
In case you are really interested on my detailed charging habits and related things on my V20, I discussed them while reviewing my batteries a while back on the V20 Subreddit.
Thanks!

On that Subreddit, you mentioned you cycled a couple batteries. Did you have to do the whole fully charge and fully drain thing each time you switched to the new battery, or just when you first bought the batteries?
Would like to know the answer to ^this^ as well.

No, I only did the full cycle with the first battery three times, and that was it. The only reason to do that is for the Android software of the phone to get a better sense of your battery level. Of course, it won't be as accurate the longer you go swapping between batteries as undoubtedly they will differ a bit in capacity over time. But fully running down and then fully charging a battery isn't good for its lifespan if you do it too often. The only other times you'd have to really repeat the calibration is when switching to a battery with a different capacity or switching ROMs / doing a factory reset.

So, I got a 4000 Powerbear that I'm calibrating now.
I'm also getting a 4100 Perfine.
Are they close enough that I shouldn't have to recalibrate for the 4100?

Most likely yes. I imagine most of these 4000–4300 mAh Lithium polymer batteries that started popping up this year are very similar, and some may just be rebranded from the same common factory source. Barring a defective battery, if the two batteries had a significant difference in capacity, you could see things like early shutdowns on the smaller capacity one or being stuck at a low percentage for an unusually long amount of time on the larger capacity one.
Great info.
So it looks like all other batteries on hand should not be put into rotation with the higher capacity batteries to avoid inaccurate readings in Android.

Pretty much this. I suppose one could try keeping separate copies of the batterystats.bin file from /data/system when rooted and swap them alongside the different batteries. But that sounds like too much of a pain to deal with, even if it works.

Just to add to this, I found your pics @C D for the charging instructions and there's a note about using 3200mah batteries along with the 4100mah batteries.

Does that mean that if you switch between the batteries, they'll both last as long as they should (the 4100 longer time than the orig. 3200), but the system's percent will be wrong?
My understanding is that if you calibrate the phone to recognize the full 4100mah and then use a 3200mah battery, it will shut down early (but still use the full 3200mah).
Correct. They are warning you that swapping between batteries of significantly different capacities will throw off the accuracy of the phone's battery percentage indicator at all times, especially at the high and low percent values (so an early shutdown can happen when the smaller capacity battery is used). Of course, this won't affect either battery's true capacity.
I'd pay good money for a system that can correctly handle different battery capacities of any amount, but we all know where the future of hand-removable batteries has been heading for the last 3–4 years.
Does anyone charge their phone ONLY to 80 % or so?
If so, what apps do you use to limit this? Any other tips/advice?

I use AccuBattery and it has a notification sound that plays when you hit the target charge percentage, but it's still up to you to remove the phone from the charger or else it continues charging to 100%.
Since our phones have replaceable batteries, I haven't made any special effort to take care of them. I have a pair of May '17 OEM 3200 mAh batteries that are going to get switched out for a pair of new 4100+ mAh Li-Po batteries once I get my second V20 set up. Every charger I use is QuickCharge 3.0 certified except for USB on my PCs and my Pioneer Android Auto headunit USB connection in one car. The vast majority of the time, I charge via QC 3.0. Pretty much the only time I let the battery charge via PC USB is when I actually need to transfer files between the phone and computer.
Before my phone started having issues in the past month with a phantom power drain, I would let the phone charge from 30-40% to 80-90% and then remove it from the charger at night before going to sleep. In the last half year as the batteries have aged, I've let it get up to between 90-95% before unplugging. For the past month, I've been charging the phone four times a day from 40-100% to combat the power drain issue, but that comes with knowing that I don't care about these old batteries or the state of the firmware on this first V20 anymore.
As for when I swapped the two batteries I have, that entirely depended on when I actually ran one down so far that I needed a 0-100% battery swap, which could be months at a time and usually happened while on vacation or away from a charging source for a longer period of time than what my usual home/car/work routine allows.

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
