Hi
I have a TF700T, unlocked, TWRP and CROMI 3.0.4.
My battery meter is acting weird. For example I recharged both my tab and the dock this afternoon. I unplugged them around 16:30. I've been using my tab for the last few hours (it's now past midnight), not all the time, but quite often. The meter on the tab is still showing 100%. The one for the dock is showing 94%. This is not the normal behavior of my tab and it's been doing that since I unlocked and installed TWRP and CROMI. Before, it would start to go down almost immediately, and would start recharging only at 70%, like it's supposed to.
Last time it stayed at 100% for a while and then started to drain very quickly, and then stabilized and started to act normally.
I'm trying to understand whatcould be the problem. Last time it got "stuck" like that I went to recovery and TWRP was also showing 100% power left. So it's not CROMI. But it's something... Anybody else with the same problem? Or anyone got a solution, an idea? Because I'm worried this will get worse...
Thanks
You could try clearing the battery stats. I think TWRP has the option to do it, not sure about CWM.
Ok thanks sdbags, I'll look into that...
Is there an ideal moment to do that? After a full recharge?
Usually you do 100% charge, clear stats, reboot let it get back to 100% and unplug but to be honest it probably doesn't really matter.
You'll know fairly soon if you still have the problem.
I just checked mine and it started with tablet battery until down to 89%, then dock battery kick in maintain the tablet battery around 89-90%.
The dock shouldn't recharge the tab unless it reaches 70% or lower. At least it's what it was doing before, and what's documented as normal behavior. Since my tab spends 99% of its time docked, I don't know how it would behave undocked...
Looks like it solved the problem for now. Thanks sbdags!

Well, unfortunately, it isn't solved. When I deleted batterystats.bin it went back to "normal" at first, the tab was fully charged and it started to go down almost immediatly after I unplugged it. But yesterday it died on me while the gauge was still showing a little bit less than 30%!!! I did a full charge last night, and it's back to its old tricks: stucked at 100% for the last 8 hours (overnight).
This is very annoying... Is there anything I can do to recalibrate the battery gauge?
And why is this happening? I didn't have this problem when locked with stock ROM and recovery... I'm not complaining, I just want to understand and maybe try to fix this! Thanks!

Could be a battery hardware issue? Sounds like it's not reporting its current and voltage correctly.
You need to get some battery monitoring apps on it so you can see what is really going on.

Could be, but it's weird that it started just after I decided to unlock. It was fine the first 4 months of its life...
Any battery monitoring app you recommend? There are a few on Google Play... I have Battery Widget Reborn, it does some monitoring, but it doesn't provide a lot of information. I'm sure there is an "ultimate battery app" or something... Any suggestion will be greatly appreciated!

Ok, thanks... Will try that and report!
Ok... So I did some testing... My tab is shutting down (more like crashing) at 28% and showing 6561 mV. I then have to plug it in and wait for 5-8 minutes before it will allow me to boot it.
So I plugged it in... It reached 100% at 8169 mV... But then, it continued to charge. As of now, it is at 8296 and still going up as I'm writing this!!
This issue is the same as issue #2 in this thread:
http://forum.xda-developers.com/showthread.php?t=2090826
Now, I don't know, but it look suspicious to me that this problem started when I installed TWRP and CROMI. Could it be related, somehow??

What happens if you wipe the battery stats again?
The only other thing I can recommended is a total wipe, reflash Asus stock to redo the bootloader, TWRP and reflash CROMI. Others don't have this problem so it is something particularly to your setup.
All those posts you linked are pointing to the 4.2.1 update causing the issue. As we only have 4.1.1 I can't see any relationship unless Asus injected some 4.2.1 code into their latest update which seems unlikely.

I suggest you should do a full wipe and reflash cleanrom and kernel. This way you can eliminated all the possiblility with software and pin it on hardware.

I have the same problem with my battery meter, and just like with you, it started when my TF700T was almost exactly 4 months old. The batteries (dock and tablet) have to be close to drained. I've been using the tablet without batteries for many hours, both yesterday and today. But my tablet battery is showing 100% and the dock battery is at 95%. That has to be wrong.
I have GSam Battery Monitor Pro. It can only tell me about the tablet battery (it's blind to the dock battery). Yesterday when I looked at this, it was telling me that the screen used no power. I'm looking at it now and it says that screen is using 68.6% of the power - that's more like it. But it's weird that yesterday the number was zero. It tells me that the unit has only been unplugged for 5 seconds, and has been telling me that since I unplugged it yesterday. GSam usually saves history, but not in this case because it thinks the unit has only been running on battery power for 5 seconds.
I also have a battery widget that is dual-battery aware. It has a history chart, but it doesn't tell me much. It shows the tablet battery at a constant level of 100% with no dips, and the dock battery very slowly dropping from 100% to 95% over the last two days. This is just wrong.
What's been happening is that the tablet will suddenly shut down when I think it's charged, and then I can't turn it on. I didn't realize what was wrong until I discovered that if I plugged it in for a while, I could turn it on again. Obviously the battery is draining completely, but the meter is incorrect. Also, draining the battery completely then recharging to green (which I hope still means "complete charge") has done nothing to recalibrate the battery.
I'm afraid this is a hardware problem. I guess I need to contact Asus?
I'm also having problems with constant browser crashes - doesn't matter what browser it is, I've tried them all. In general, this tablet has been a huge and expensive disappointment.
Edit: I'm running ICS 4.0.3 stock, rooted but not unlocked. I don't want to upgrade to JB because I need the volume booster app. I've read that the volume problem is just as bad under JB but the volume booster apps don't work (nor do many other programs I use). There is nothing in JB I need. From what I've read, people running JB have all the same browser crash problems, battery meter problems, etc.

I feel your frustration, I have seen more and more people with this issue. Well, we could say that either software or hardware, (not every situation is the same), so usually I recommend to do a factory reset then reflash a full Asus firmware, if the issue stills existed, then we can assume it's hardware issue. At this point, we can give Asus tech support a call.

Thanks for your reply. Have you heard back from anyone who has done a factory reset and reflashed the Asus firmware? Has anyone reported the problem going away after that?
The other thing I'm worried about is that it's a hardware problem that Asus doesn't know how to fix because they don't yet know what's causing it. I can't recall anyone saying they've found a solution to this. I've only seen reports of the problem.
I have other serious problems with this tablet, too. It runs short of memory all the time, though this isn't supposed to happen on Androids. I often have to manually clear memory to view screenshots in the Play Store. And the browser is constantly stalling, freezing, and crashing - every browser. I've tried more than 5 of them. This is especially inconvenient for me, since I make heavy use of the browser on the tablet.
I keep thinking of that pressure-sensitive Samsung tablet I almost bought instead...
Running kitkat, battery recently replaced. all good for a month.
Yesterday the phone suddenly switched off , i switched it on again and the battery had jumped down about 40%.
It crashed again but then remained stable for the rest of the day.
Tonight (at 50% battery remaining) i got a sudden warning "6% battery remaining" and it crashed again, i switched on again and the battery went back to normal , around 40%, stable since.
Any ideas or is the phone on the way out ?
Did you buy an official N5 battery? It looks like a faulty battery...
This is the one i ordered

It can't do any harm but it won't help in this situation.
Try the following:
1. Let the battery go to 5% then charge your device to 100%
2. Disconnect the cable
3. Reconnect it and check if the battery level is at 100%. If not keep charging. If 100% disconnect and reboot. Then reconnect until 100%
These steps worked for some users (even if steps 1 & 2 should be enough IMHO).
Moreover you can try to remove apps or flash the factory images to check if the problem persists. If nothing works then your last attempt is to send it back to ReplaceBase.
thanks for taking the time to reply, will try your suggestions,
Just had another strange battery drain, captured it on this screenshot.
You can see battery just takes a sudden dive and recovers somewhat.

I have just read a nice thread about massive battery drain. Check this out.
His explanations fit with your battery stats.
Thanks for that, will have a browse, but would it explain my phone suddenly dying at 50% ?

I guess. Anyway you should follow the above steps and clean up your device by removing useless apps/features. Finally flashing factory images is sometimes a good thing to start from scratch.
Thanks again
I just tried your first suggestion, charged till 100% then disconnect, it immediately dropped to 99% so i recharged to 100%
Then disconnected and rebooted, weirdly when the phone rebooted it said the battery was now at 19% ,
Back on charge again.
Ugh.... Good luck but I would bet on a faulty battery. You'll probably have to send it back if you can use the warranty.
Did you have the same issue after receiving the new battery? Did you change several things of your setup (kernel, new apps...)?
Going from 100% to 19% can't be explained by the above thread. IMO no apps, no kernel, no software can explain this drop. Some folks say that it can also be caused by the motherboard...
Replacebase have promised to send me out a new battery , they too think its likely a dodgy battery, top customer service so far, hopefully it wont take too long to arrive.
I didnt change anything on my phone, perhaps updated some apps , its stock Kitkat,,, meanwhile Is there any way to check the health of the motherboard ? i don't like the sound of that.

Without profesionnal tools we can't check this AFAIK. Don't worry about the motherboard. It was only a suggestion reported by a few users. Chances are your problem will be solved after receiving the new battery.
ok thought as much, battery charged up to 100%, rebooted and now at 60%.
Ill put back in the old battery for now and see how it behaves. thanks for you help
So my Moto X dies at ~20% charge, which is bad, but not entirely surprising for an 18 month old phone (despite the fact that I rarely use it, which is disappointing and continues to reiterate my point that Motorola QA, before or after Lenovo, sucks). The strange thing is that if I plug it in then, the charging screen on the screen off shows 1%, then 2%. If i turn it on then, the boot is normal, then on lock screen, it shows 25-29%. Any fixes?
try calibrate battery, it happend to me a lot of times and after calibrate doesnt happend, only when i change rom
Update, phone is now being very wonky. See graph for details:
I have the same issue
Same problem here. Xt1097, started 3 months ago. Already wiped battery, delete files, completed charged and discharged. Nothing works. I was running stock when first happened, I changed to custom and the problem persists.
Mine does the same, except at around 14%. XT1095
Same here (xt1097), around 10%. Already tried to calibrate without any success.
Any thoughs on this ?
Same issue here at about 15%. Pretty annoying. Is there any way to adjust the kernel to adjust shutoff voltage or adjust battery so is shows 15% as 0%?
Reporting on the same problem, I'm running CM13

The battery is dying. There's no software capable of fixing this. Replace it.
I solved the problem with a clean instal of stock rom and take the OTAs. I used the phone without root for some days and I completely discharge it, when it shut down I recharged the phone keeping it powered off , when it was charged I turned on the phone and then rebooted it, then I unplugged the phone (I did a battery calibration). After some days I rooted again (latest supersu in systemless mode) and flashed xposed (systemless version 86.2), but I didn't restore all my xposed and rooted crap. Battery life is still quite poor, but the phone didn't shut down at random percentage... I don't know if the issue was caused by some app or root method, maybe restoring stock rom helped, before doing all this stuff I tried just to calibrate battery but didn't solve the problem.
I know it's not really a solution, but I found that activating the system battery saver around 20% helps getting down to 10% without the thing turning off. I haven't tested below that yet.

Battery dying fix
1. Shut down Moto
2. Hold volume down and power button
3. Clear dalvik cache
4. Let it charge to 100%
Hey guys, I'm having severe battery drain with my new Xperia XZ. The phone basically never goes into deep sleep and I have no idea what the cause could be. I'm on the latest firmware. These are the battery stats overnight when I wasn't using the phone.
I have the same problem with my xz

There must be something wrong with the software, since I'm also experiencing twice the time of phone activity than screen-on time. I have contacted Sony Customer Service and they advised me to do factory reset and since I had no time to do it lately, I can not say if it worked. If you have spare time to backup and restore your data, you should go for it. Keep me informed of results
Not here
Sorry to hear that guys.... My xz is running with the last software update also, but the battery drain during night doesn't exceed 4-5%. Wifi always on, alarm and stuff....
I have done a factory reset and used the pc program to repair the software and still android os is taking many %

Factory reset doesnt changed anything
Every time you factory reset and/or flash something it takes a while for the android OS to rebuild caches etc.
Please see how this goes over a week and then see if there are any issues.
If you still have no deep sleep or wake locks then you will need to provide logs in order for anyone to have an idea what is causing it.

Now my android os is down to 10% so i think is going back to normal again

No issues with battery here. When I got my phone I reinstalled the OS right away through the Sony companion. Maybe try that. Will check what happens overnight since I got the phone just yesterday.
I didn't got an issue with CPU, but my XZ battery drain over night is about 4-5% (did check and close/disable all apps and connections ) and by day use is too high (may not last a full day with facebook checking & web surfing frequently, full at 7am to 20% at 7pm ). (I did use Z1 before, and that is quite terrible cuz Z1 did last longer when it was still new)
Hope nougat update fix that :'(.
I've had the phone for just about a week, so I'll give it some time and see if it settles, especially considering my brother's Xperia XZ doesn't suffer from the same issue. Thanks. Well at least the Nougat rollout has begun.
Update:
I did Factory reset with software repair (via Xperia Companion) and after reinstalling my apps and whole night charging I saw little improvement...
My 2nd thought is "Smart Cleaner". Since I have installed some really badly made apps like Facebook, Messeneger or Snapchat, my observation is that they don't like to have cache cleaned. So I have turned it off and magically my issue is gone. Deepsleep 95% of time.
IMHO every performance improving software feature must have some issue...
does the drain fixed with new N update?
im still using MM and suffering from this prob badly

I do hope Nougat fixes it. I guess we'll find out soon enough.
Very poorly holds the battery in this phone. I am almost collapsed!
Happy Xperia XZ & Z3Dual user
Despite the battery size it does what was advertised.
No root,
Not unlocked
No custom ROM
All info is stock Android N from my XZ. I can get easy 4 hours SOT through the day.
I don't bother with stamina, it's not the same since before 6.0. Just cripples performance. Huawei have somehow managed to implement stamina style features into their 6.0 ROMs. If Sony manage to do the same I'll use it again.
But then, I've had over 3 hours screen on today and still have 57% left, more than happy with that given my cell reception is never over 2 bars here.

Firstly i had 33.3.A.0.131 with good battery life (pretty much much better) but then after using it for a couple of months i noticed it drains much faster. I thought something about the battery, that it is kinda small only 2300, but then i upgraded to 33.3.A.1.97 and noticed the battery went back to normal. again drops 2 3 % over night... so im thinking it may be somekind of battery reset during upgrade over OTA. Maybe someone knows how to do it manualy without upgrading (clear cache??)/ restoring firmware with full wipe? could be useful if that happens again

You can reset battery stats by wiping "Qnovo" partition with Flashtool.
thank you
Apologies in advance for resurrecting an old thread.
I flashed stock firmware onto my phone to downgrade for rooting. I've done that before with success. But with this new phone (Xperia XZ1 Compact) I didn't realize that I need to *not* flash some partitions. Qnovo is one of those . I did not back it up before doing this. I know, rookie mistakes.
It was fully charged before flashing, and after it shows 20% charge, and never goes up. Red warning light on, unless the phone is off, then it's green.
Seems like the Qnovo partition is messed up in some way. How exactly do I wipe it? Can that be done without flashing the whole phone? I can't see an obvious option in flashtool, and tried fastboot format Qnovo (that doesn't find the partition and does nothing).
