battery quality/durability - Moto Z2 Force Questions & Answers

Hi everyone,
does anybody know if the Moto Z2 force also has the same battery issue as stated in this thread for the Moto Z? https://forum.xda-developers.com/moto-z/help/issue-2-crazy-battery-behaviours-t3680766
Could somebody check if this batt_health binary is also excluded from running on unlocked bootloaders on our device or if it's even existing?
I definitely had the worsening capacity problem and the inability to boot phone under 30% charge problem on my Moto Z.
Kind regards

Me too (on old Griffin).
I arrived to be unable to power on up to 50% of battery (and Accubattery reported a capacity as low as 900mAh ) except that on bootloader mode...
And when I left it to an assistance center to change battery... they destroyed my screen...
I hope the quality on Nash would be better... (battery are different anyway...).

I will check into if that is working or not, currently estimated battery mAh is near correct...
Edit: XDA image derp: will show soon. Accubattery estimates near 2600 mAh (2592.2)
Edit 2: yes, it's there and populated. System/bin/batt_health

On mine are a bit higher: about 2630-2650 mAh with wireless charging by Incipio Mod and about 2710-2750 mAh with a (good) wired & "not-so-fast" charger...
Since of my experiences I think your lower values are because of stock charger doing fast charging...

That was USB charging. I left it on my Linux box for the day, so it was slow charging. Below is overnight fast charger estimate.

Well... one single charge with only 33% charged is not so significative (on Z2 partial charging often reports BIG battery estimates... I've just done one of about 25% which reports over 4,000 mAh... :laugh: )
Go with at least a week of various recharge of at least 65-75% to have significative results ...
When my old Z begun to have a dead battery I was able to charge up to 1,500 mAh with a slow charger BUT less than 1,000 mAh with its fast one...

My phone barely goes under 50% though...
It's better for batteries of this makeup to stay between 50% and 80%. Anything out of that range will drastically affect battery longevity. EG: my VZW M7, I got it pretty much the week it came out. Verizon had a BOGO deal, so the wife got one as well. She always drained it to 10% before charging to full. Hers started seeing shorter battery life after about a year when my battery was fine and it finally went out due to the known emmc defect three years later.
I try to make sure my phone is unplugged around 80% just so battery stats reset like they are supposed to after being taken off the charger over 80%.
In essence, charging 65-75% in one cycle hurts your battery if you're looking to keep the device for awhile since it is a pain in the ass to swap batteries now.

I know, but I was only talking about statistics point of view...
In fact I prefer slow charge whenever is possible and I follow Accubattery hints as more as possible...

Does the official Sprint 2600mAh battery suffer from the "charging bug"

So most people are familiar with the seeming "bug" that if you slap in a huge extended battery (Seido 3600mAh one comes to mind) if you are charging via USB it would only charge up to the 50-60% mark
I'm seriously thinking about getting a sprint extended battery - but does this bigger battery suffer from the same "problem"
I know this one is Lithium Polymoer instead of Li Ion... does that change anything?
All I know is that I refuse to take my battery out every 24 or 36 hours to "wall charge" it directly.
Thanks in advance for you input!

Mine has been charging perfectly... have had it two days, and it's been great
thanks for the quick reply -- I'll try and pick one up here in the next few days. I'm sure I can take it back if the huge back or if i had any charging issues
would be nice to go 24 hours and not have to worry about the battery at all
I have loved it... i have been able to actually use my phone.... and i even had them credit me $20 for buying the battery
You could have posted in the thread in this section, just a few posts down. But to answer your question, I have not had any issues yet. I know it drops by 3-4% a little quick (30 minutes - 1 hour) but that is the only major drop I see.

Li-Po is actually not going to change anything except that you can put more cells in the same size battery, therefore increasing the length between charges.
Most of the LI-Ion batteries used in phones are LI-po now adays anyways. The orignial evo batteries are. and most of the extended batteries are as well.

Actually, they haven't used Li-Ion batteries in most consumer electronics for several years but the name has become a generic descriptor for an entire family of cells which include LiPos.
The complete name for LiPo is lithium-ion polymer and they differ from lithium-ion cells in several ways including:
The electrolyte in a Li-Ion cell is a gel (liquid) while the electrolyte in a LiPo cell is a solid polymer.
The layers in a Li-Ion cell need to be tightly compressed so they're typically rolled and housed in a tight-fitting cylindrical case, but the layers in a LiPo cell don't require that compression which is why they can be manufactured in that handy flat form factor so easily.
The nominal working voltage of Li-Ion cells is 3.6V and it's 3.7V for LiPo cells.
LiPo cells have a higher energy density (capacity/weight) than Li-Ion cells.
LiPo cells can be charged and discharged at significantly higher rates than Li-Ion cells.
The bottom line is any small consumer electronics battery pack which is flat and square and is marked as 3.7V (or a multiple of that number for multi-cell series-wired packs) is a LiPo pack regardless of what it says on the pack or in the literature.

I have owned both batteries and I'm quite familiar with the bug OP is referring to. I can say unequivocally this battery has the same issues the 3500mah Seidio battery does. If you charge this battery, while the phone is on, to max and then unplug, you will watch your charge drop from full to in the 60s in the first hour or two. The drain then tapers off significantly at that point.
I haven't really had an opportunity to put this one through it's paces yet and it may stabilize over time. I'm thinking that this new one might provide the same amount of battery life as the Seidio 3500mah one due to this bug.
EDIT: See my post on the following page. The battery/system seems to have calibrated itself.
You mean to tell me that this battery was a waste of money for me? If so, let me know. It will go back tomorrow
Strange, I don't have this issue at all and I've had the battery for almost a week. It tends to drain quickly to 95% then level out.

My second charge drained to about 60% just like the first. I just pulled it off the charger for the third time early this morning and I am not noticing the drain anymore. I'm thinking it must have calibrated itself.
I've been off the charger for 1 hour 50 mins and I still have 93% remaining!
This is much more like the stock battery. If it continues to act this way, this battery beats the Seidio one by a mile. It's been a couple months since I've used the EVO. Has something been changed in the CyanogenMod Supersonic kernel to support extended batteries?
Shouldn't it be draining slower than stock battery?
I ahve the Seidio battery and I have never seen the battery drop to 60 percent or anything else like what people are saying. I am on CM 6 RC1 but even with any of the other dozen ROMs I have never had an issue. If my battery dropped to 60 percent a short time after unplugging it I would have sent it back the same day.
I charged my battery from 5% to full last night via usb charge. I pulled it this morning at 7:00 and it dropped to 93% quick mainly because it was on the charger well after it had reached 100%. Since 7 am Its dropped as it should. Im currently at 71% 8 1/2 hours later. So I wouldnt say all of these batteries have the 3500 seidio issue. What rom is everyone whos having the issue running?
They may have fixed something in the kernel recently to avoid this. Look up the old threads about the 3500mah battery. The battery calibration issues were universal.

The EVO stops charging at 100% and will not charge until it drains back to about 90%. The phone will continue to show "full" until you pull the plug. It will then show the true charge level.

Thanks for clearing that up. I didn't read your previous post, I guess
So do you guys suggest to get this instead of the Seidio ?
Someone take a logcat dump and look at the battery parameters of charging/not charging and you'll know if they've fixed the issue or not.
The meter will self adjust to the 1500Mah based on voltage and you think you'll get a full charge but you won't. Slapping it into an external battery charger after "fully" charging it thru the evo will open your eyes to the issue.
Here's hoping, now there's a sprint official "OEM" class extended battery that they'll get HTC to compile in additional battery drivers other than just the 1500mah one it shipped with.
Sorry folks, if you can't charge it externally, you're not going to get the FULL capability of the battery. There are ways to tricking it into taking more. Charge it fully with phone on, unplug, power it off, charge some more, unplug power on, charge more, etc.
This will continue to add just a little bit more to help bring it up, but you'll never get it full unless you can charge externally or HTC adds devices.
You can pull the source code yourself and confirm this info. You can also confirm the issue still exists with an external charger.

the truth about HTC extended batteries which claim same size , higher capacity

Under mango or one of the firmware updates which had been updated recently , u will see yr battery saver is fluctuating , at one time saying u have a 1 day, while another time it says u only 2 hours on a reasonably fuller charge.
there is a problem with HTC original batteries, rather i will say a safety regulation after recent incidents with battery safety
yr htc only charges up to 85% level even though the phone indicator shows 100%
when u unplug it from the charger, it immediately drains and stays at 80%.
THis is likely why the HTC phones have a shorter battery life, whether its android or windowsphone 7
this is not a defective battery, its made intentionally by HTC for 2 reasons 1) safety , 2)battery longevity ,the safety mechanism built in stops charging it to 100%, thus overcharging, overcharging means the battery is out thru stress which may pose a hazard. if a battery is fully charged to true 100 % , it poses a hazard if one of the pins in the phone connectors break. apparently this pin tells the charger or the phone not to charge anymore once reaching 100%. there is a possibility that if this pin breaks, the phone will overcharge and pose a safety hazard. So this is why HTC batteries dont charge to true 100% and this particular pin is tweaked to full charge to only 80%
wheareas, mugen batteries ect do not have this safety regulation or charging limit although they are safe to use, so they seem to last 20% more than stock HTC battery because they fully charge to 100%.
Mugen or other reputed aftermarket batteries are more likely to wear out sooner than stock batteries unless depending on the quality of the battery..
in order to get yr HTC battery to full charge it u need to bump charge it.bump charging is a technique to fully charged the battery closer to its real capacity
to bump charge
1) fully charge the battery from 20% to 100% , as indicated by the phone OS
2) turn off the charger, turn on again, u will notice the phone charges again even though its 100% full for 1/2 a minute. wait for it to fully charge
3) repeat the above step 2) for 10 times
4)use a timer plug to simplify the process. Set the timer plug to on/off every minute for 10 times. u need to get a digital timer for this purpose with mutiple timer settings

Interesting. I noticed this with my HTC Mozart; battery indiactor drops one bar (to 80-85%) as soon as I take it off charge. Always assumed it was a WP7 thing - like it was drawing a lot of current.
Where did you get this info from? Looks like I'll be ordering a new (non-HTC) battery asap!
If it's true i won't buy a plug timer but a new battery, not from HTC...at least i hope it's true caus my battery capacity sucks and that gives me hopes, enjoying my hd7 more than a half day without plugging it (when it's possible)...so nuff thanks for the tip.

Funny, I have always done this with every device (maybe not the x 10 repeat!). never knoew that was the reason though thanks!!
not only HTC, there are couple of other devices like samsung galaxy ect
now u know why they claim mugen and other aftermarket batteries last longer...
mugen 1500 mah battery with the same size as the stock 1230 mah batt>
thats bull..because a 1500 mah battery looks much bigger ... the samsung omnia 7 has a 1500 mah battery and its 30% larger than than the HD7 battery....

thats because the battery stops charging once it reaches 85%
u may have heard of the HTC bump charging technique. thats what this si all about , but u need to do it everyday, so get a timer plug and leave it to do its job overnight everyday
the best is to use a digital programmable timer plug .
Ok, had a google and looks like your post is only partially true:
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
Appears it's an issue with all smartphones, not just HTC! Also bump-charging will dramatically reduce battery life.
As someone in the comments says; why can't the phone just stop charging and switch to running wall power once battery gets to 100%, same as laptops? I assume this is what Apple do, as the iPhone doesn't suffer from the same issue.
Interesting because I have no problems with my battery doing that running Mango beta 7712 on my HTC 7 Pro.
The moment I take my battery off once it turns green, it stays at 100% for hours if there's absolutely no activity on it.
I think it's how far you guys are draining your batteries. Ever since I've gotten my phone, only twice did I push the battery lower than 15% charge; once on accident and another to recalibrate it. After that, I never pushed it lower than 15% and made sure to only recharge it after at least a good 20% of usage (days i feared i wouldn't be near a charger and needed full charge).
Granted, I'll add that it maybe be because I swap the battery out every other night with a spare, and if I do so I make sure there's between 50-58% charge left.
No bump charging either.

yes its better to maintain 20% charge .
If u noticed the iPhone batteries wear out faster.
About year or so.
Just to confirm I have used the timer plug technique twice the last 2 days .
This is what I have
30% charge
8 hours since last charge
Moderate usage.
Somehow those who claim to use momax or mugen batteries claim to have the same results above .
the charge-controller is in the phone not the battery.

My HD7 doesn't do this. Tried several times even over a 5 minute span keeping the battery indicator in view. It never dropped to 80%.

You should not let Li-ION batteries fully discharge, ever. It's good to keep it on a charger whenever you can, than keep it off a charger and let it fully discharge. That wears the battery out.
Also, there's no risk in overcharging the battery because almost all decent phones will stop charging when the battery is full. They know when to stop charging, just like they know when to alert you that the battery is fully-charged (via a notification and/or changing the LED Notification light color).
You actually can overcharge it by exposing a fully charged battery to higher temperatures - putting the phone in direct sunlight or setting it in a car holder in the way of hot air from the heater deflector while using Satnav, for example. In order to avoid these conditions, controllers do prevent batteries from 100% charge. That being said, I don't think there's a standard for marking battery capacity, and an honest manufacturer should put real effective battery assembly capacity accounting for those limitations, not the sum of capacities of included cells. Don't think they do it really.

It's actually still not good to leave li-ion batteries plugged in when they are fully charged and stopped charging. They will suffer from capacity loss that way as well. Not to mention any heat coming off the device.
Update: i did not bump charge today..
and the old symptom returned again.. draining fast

[Q] Charging speed indicator

Coming from a galaxy S3, there were apps, including one called "Galaxy charging lite",
which measured how fast the charger charges the phone's battery (mah rate).
I can't find an app which works the same for the LG G3.
Does anybody know of an app which measures the mah rate in the LG G3?
Thanks in advance!
Gsam battery monitor
Another app which provides weird results. Says Im charging at -314ma. This is not true.
Discharge is positive so net charge current would be negative if the battery is charging.

Yeah, but 300mah is not correct. Should be closer to 1500mah.
I get a full charge between 45 minutes to an hour fifteen. Ill time it when it goes completly dead today. But i feel like id be around 2300mah charge at least

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Moto Z2 Play can charge. A higher rating indicates that it charges extremely fast.

4 hours? seems a little low, i get easily 3 day with the battery mod, and never had a problem getting to bed with phone still alive, so it last at least 1 day. i have normal usage, social media, couple video calls, online banking, tickets etc...alsa charging is fast for me, i come from a moto g2
The phone heats up a lot while charging with its TurboPower charger, it would be nice a toggle for disabling QuickCharge when not needed.
I never had better phone in my life. Charging is amazing fast, and Moto turbo power mod is awesome. No need to leave phone for charging, leave Moto mod and put on the phone while done. Usually for me it is a matter if I can disconnect charging before phone battery reaches 80%. After over a year battery status shows my phone still has 2850mAh, but all the degradation is taken by Moto mod. Time to change it, but of course... not able to buy it anywhere.
Was great first year when 10w charge was working. Now takes forever and only lasts 4 hours like the guy said. Too bad it uses internal battery.
I just bought a XT170-9.
Battery was 0%, production date exactly 2 years ago.
I think I will return the phone. A lithium battery that has been empty for an unknown period of time is not new any more.
Charging time with 3A 15 W is
30 min - 50%,
60 min - 80%
70 min - 90%
is this normal or too fast for a new battery?
I used USB C PD 18 watts and it's charging rather quickly.
Yes, it supports 18 watts PD charging

50% in 30min is pretty standard, most QC 3.0 takes near that time to reach 50%
I don't know about 80% and 90% either, but I think not having the battery charged for a long time doesn't affect Quick Charge charging time.
But you are right, you should return the phone. I have had bad experiences with batteries being dead 0% for a long time.

Thanks for the answer. I decided to keep the phone. It's a year since I bought the phone and I believe I start to see some drop in capacity now. but apart from that the phone has a very good battery.
Well, low charging times could indicate low capacity...

What kind of charger are you using? Motorola Turbopower 18w?
You know, brand new phones don't have their batteries draining earlier, they at least last like 1-2 years before you notice drop in battery life. If the drop is sudden like from 1 month or 2 them the battery might be the problem, but then since its Moto Z you could try buying those Battery Pack Mods, and they're sort of a strike of luck to get one that actually works the best since regarding Moto Mods people has mixed opinions towards them, because not all of them works flawlessly and some may get faulty mods, which is why there are negative opinions towards them.

Yeah, I got two Moto 18 W charger and one 12 V Anker USB-C charger which delivers similar power.
that's a good idea, to buy a battery mod instead of replacing the battery. will keep that in mind.
At least you could disassemble the mod and replace the battery and won't risk damaging your phone.
only drawback: the mods are super heavy, got the Hasselblad and the Sound Mod.

Battery Health in AccuBattery

I purchased my 5t about 4 weeks ago and the stats in AccuBattery are now showing my capacity at 2930 mah and the health at 89%. If accurate, these are somewhat concerning considering how new the phone is. Anyone else seeing similar stats? I ran AccuBattery on my Nexus 6p and it always seems pretty accurate.
That's the same capacity I get on my phone with AccuBattery. Other people on the OnePlus forums also had the same results so I think that it is probably normal.
I don't trust that application any more (even if I bought it 2 days ago). So i purchased my phone 4 days ago and after the second charge it says 89%.... Many battery applications are useless on the Play Store.
It is a little wonky on certain phones sometimes. Have you done several charge and discharge cycles? I know it definitely won't be too accurate until you run it a few times. Since you said you used it on your 6P though, I'm guessing you know this already. As long as battery life is still good, I guess I wouldn't worry too much.
I run Accubattery on my mine, it says 92% after a couple of weeks. Battery lasts for a full day of heavy use, and then some.
I also ran it on my 2 year old Moto X Style, and it said 51% - and I felt it was telling the truth, since I got about 2hrs SOT from it if i was lucky!
Same for me, showing about ~3000 mAh from the beginning.
It's also showing ~107% on a Nokia 3 of a friend of mine, so I guess you just can't trust the app on that perspective.
lol, guys
ok now, several factors to consider before you jump to conclusions (ive been using accubattery for several months now with great results):
1) your sample size is waaay too small. every scientist/engineer/mathematician, etc out there will tell you that u cant jump to a conclusion based on just two samples. give it some time, use the app regularly for several weeks and only THEN can you make assumptions about the accuracy of the collected data.
2) ive noticed that the final capacity reading is more accurate, the closer a charge cycle is to 100%. which makes sense if you think about current quick charging technologies: they provide high amperage at steady voltage at first up to like 75-85%, then they switch more and more to trickle charge with low amperage. advantages: fill up the battery quickly, but without putting too much wear onto it.
thus: if you just do a quick charge cycle, say from 30-50% then the slope steepness is way higher, thus the calculated capacity will differ. so there is a dilemma: either do large charging cycles with higher wear on the battery, but more accurate capacity data in the end, or do smaller charging cycles with inaccurate data but less wear on the battery.
3) when charging to 100%, dont unplug the phone when it reads 100%! rather check the current charging amperage in accubattery. only when that drops to zero (or -1 mA in my case) is the battery fully charged and ull get a more accurate capacity reading than when stopping the charge when 100% is reached. if you unplug it too early, the capacity calculation will be on the low side
hope this helps!
cheers

your sample size is waaay too small. every scientist/engineer/mathematician, etc out there will tell you that u cant jump to a conclusion based on just two samples.

Yup, am scientist, can confirm
Same thing happened to me, even after using AccuBattery for a couple of weeks (and thus collecting more than a couple of samples, both Dash charge and "normal") it still showed 89% battery health at around 2940 mAh. Got my phone one month ago.
I don't think there's any problem with the battery itself, especially as it's not just me having this problem.
Maybe the battery is 3000mah and they are lying about it ???

what kind of charging cycles did u have? the range i mean...

I'd say 30% of the times 10 to 100%
40% of the times 30/40 to 100%
And the rest just random stuff: 50 to 100, some top ups here and there
This is not scientific data though, that's just what I recall from the couple of weeks I used AccuBattery. I'll try to find a screenshot but I doubt I have any.
I reinstalled it today and from a single 14 to 80% charge it gave me ~2930 mAh and 89% health. I'm on OOS 5.0.2 stable, will try the app for some time and share my results (more scientific this time)
After several weeks of use, the reading is still constant at 86% ~ 2827mAh. Not sure what to think. As previously mentioned the first 5t I purchased and returned for the 128gb version came in at 89% same as @Explyy. Is it possible I have an inferior battery?
hm, there indeed seems to be a pattern emerging with so many different users reporting identical capacity values at 2900-3000 mAh for their new op 5t. two possibilities: either accubattery cannot properly read out and analyze the 5t's battery charge controller. or the battery capacity is indeed around 2900-3000 mAh instead of the advertized 3300. its normal for battery capacities to be around -100 mAh from the official value, but -300 to -400 would be crazy.
guys, just to be sure: did you leave your phones plugged in until the charging rate in accubattery dropped to 0 mA? as i said before, if you unplug the phone once it shows 100% but still charging, the resulting capacity will be less than the actual one.

Yes, I left the phone plugged until the charging current dropped to 0, as I noticed that when it reaches 100 it's still charging at a few mA
On a related note I charged my battery from 10% to 100%, until the mA rate dropped to 0mA. I had the phone hooked up to a USB power meter during this time. The USB meter only read about 2500mAh charged. So since I only charged 90% of the battery I figured it should be around 90% the capacity of the battery, which is 2,970mAh. If I assume the battery is 3000mAh then a 90% charge would be around 2700mAh, closer to my reading. I'm going to run some more charge cycles and see if I get the same results.
Edit: forgot to say that I used a standard 2amp charger, not the dash charger that came with the phone.

Did you use the dash adapter or just a regular one?

and still no difference in the calculated capacity in that particular cycle?

As far as I remember no, always reading ~2950mAh

Someone who's having accubattery report ~3000 mah should download AIDA64 and look and see what it reports the battery size to be......
