Weird battery meter problem

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!

Try battery monitor widget. It does everything you need.

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...

Oneplus One dies at 20% battery charge rate

Few days back, my phone died even if it showed that battery has about 20%. Since then, my phone dies always near 20% charge state. Before it does, screen is flickering a little bit.
But so far I've observed, my phone runs about 1 hour and it still shows 100%. After that, it starts to drop. I've tried some calibration, but it never worked.
Do you know, how I can repair this or it's a subject for official repair? I would've tried to buy new batteries, but since it's OPO where batteries cannot be changed, or can be, but it brakes warranty so...
Thank you guys, appreciated.

How old is your OPO? What ROM did you use? Any custom kernel / details etc?
My OPO works fine on CM11 nightlies, stock kernel but rooted.

It's max 5 months old and I've never experienced such an issue. Down you have screenshot. I'm running stock ROM and everything. Hope it will help

I have the same issue here. Bought my One on August, running stock, suddenly since a few days ago the phone goes dead on 20% or 16%.
I hope there is a solution for this, different from "send it back".

I think you might get a faulty battery. This happened with my old galaxy note too. Changed battery and every issue is gone.

Got same issue since a few days, how to manage?
has anyone tries this https://forums.oneplus.net/threads/phone-switches-off-when-at-20-low-battery.157075/

27%
Same issue started happening with me too. Phone touched 25-27% mark and goes off suddenly. It was fine from last 3 weeks and from last 2 days, it is giving me this issue. I will try doing factory reset. Hope it works.
PS: I am on stock 38R without root.

has factory reset worked?

Reset doesn't work. It's software problem. A lot people having same issue.
Mine even worst. switched off about 35%. and lasted about 12 hours stuck on 100%.
I've done flash to stock 33R, 38R. clear everything. same. doesn't help.

Open up the phone dialer: type *#*#4636#*#*
This should bring you up to a "secret" settings page. Click on battery information. There you can check battery health!

Replied to a similar thread. I experienced the same issue where it stays at 100% for hours and died around 17%. Happened twice. What I did was turned off the phone and charged it full. Turned it on, waited a couple of minutes or so before unplugging. Had to make sure all apps in the background are up. So far it it fixed the problem for me.
Hope that helps.

I've tried out an apps call "Easy Battery Calibration" can be downloaded from playstore. for rooted devices only.
After using it. it seems okay right now. 100% no longer holds up few hours. drop 2% about 1.5 hours usage.
Looks neat. still waiting for the battery depleting .

Not really. Only did it when it died at17%. There may be some app updates that causes it. In my case I think the culprit is Gsam. Cause when it updated, it messed up the calibration. But then again, it could've been other apps that updated at that time too ☺
Sent from my OnePlus One®

I faced this previously. Phone died around 40%. Install battery calibration app from play store. Calibrated my batt and all ok till date. Rooted and on fk kernel back then.

here's the fix. no need to install additional app. no root needed.
NOTE: do this at night, just before you decide to go to bed.
1. let the device turns off itself. no matter at which battery level.
2. while the device is powered off, charge it for at least 6 hours. do not interrupt the charging. do not turn on the phone. and do use the original charger and cable.
3. once the phone is charged for at least 6 hours. turn it on and use it as per your usual way.
4. repeat step 1 to 3 for another 2 times. then the phone's battery calibration will be fixed.

I see you are on 38R .. Have you updated to 44?
Sent from my Nexus 4 using XDA Free mobile app

Working. Thabks.
Wondering what caused this nevertheless.
Another issue is that never before when the battery was enpty that i saw that screen with chinese words. Is that new?

Dies at 20 percent, charge for 5 mins, turns on again is 29%

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

Look for original bulk xt1092 batteries

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.

1. Shut down Moto
2. Hold volume down and power button
3. Clear dalvik cache
4. Let it charge to 100%

Battery draining insanely fast

Hi
All of a sudden my battery started draining rapidly. See the attached screenshots for ref. I thought maybe it was a software bug since it started happening 2 days ago. I tried booting into the safe mode and the fast drain didn't stop. I also did hard reset with same result. At this point I'm thinking about getting new battery. Just wanna see if xda community has any tips if maybe I've missed something. It's just strange that this sudden degradation happened overnight.

Obviously, that draining is not normal.
In the upper left corner there is a warning that some app is running in background.
When you did the hard reset also you did a restore from some backup? Is the device warm/hot?

Sometimes it shows carrier utility or people apps running in the background. I restored from Google backup (forgot to mention in the OP). Device isn't hot at all.

i stared clean with LeeDroid ROM (had original Sprint ROM on) after wiping the data and the fast battery drain remains. at this point i'm going to replace the batter since it's not a software issue.

I'd definitely say your battery has shat itself. I'd also try something like gsam or battery info in *#*#4636#*#* to see the health of your battery. I'd be interested to know if it reports it as "good" health

It's strange but the standby seems to be better now whereas it was going fast before. Thought maybe it 'fixed' itself, however during a phone call (4min) I lost %3. That's definitely not normal 4636 is not showing any battery info. Can't find anything in gsam showing health status of the battery. Is it in pro?

If the battery drains fast during calls can be due to poor/weak network reception (the modem tries to maintain the best quality and scans the network over and over).
3 sot with 50% (or little more) battery left is a good value, in my opinion.
Oh, when recoveries are made due to some problem is better to not restore from backups. In that backup can be the app or setting that is causing the problem.
Anyway, with the last google play services (14.7.99) I also have noticed a bit more drain during standby.

Sounds like you need to replace it

I have about the same issue. The battery is draining too fast and it's very noticeable when idle, even when idle in safe mode + airplane mode it loose 20% during an 7 to 8h night. I tried all htc nougat and oreo official and unofficial roms and nothing fixed the problem.
I also used the htc diagnostic tool to determine whether my battery is "good" or not and..... according to the diagnostic tool it is "good". Notice that according to diagnostic tool the battery is defective only if it goes from 100 to less than 75% during the test. Mine goes from 100 to 93 during the test which consists in showing a kind of dark grey screen at full brightness during 1 hour.
Even with a battery rated as good I decided to sent my device for repair because it was not good.
I received the device back and it has not been repaired because it passes the diagnosric tool test. test.
So i'll replace the battery myself as soon as i'll receive my new battery.
I suggest you to run the diagnostic tool test and if you get a decrease from 100 to less than 75, they should repair it under warranty, if not, suggest you to replace the battery yourself or pay somebody to do it for you.

I already ordered the battery and will do the replacement myself if the wait times are similar to those of screen replacements. Plus everything points to a bad battery so another test with official app is pointless. Sounds like we both will be doing the swap ourselves.

So I put new battery in and the drain seems slower than before and the charging is not erratic (jumping). When I was removing back cover the black layer came off so I figured it'd be good time to try clear cover mod . I like the look but unsure if anything will interfere with the radios and such due to the missing protection.

S7 Battery Drain? Or Potentially Another Problem?

So my sister upgraded her phone and gave me her old Galaxy S7. It has a problem, when left idle, it will drain its battery to 0%, essentially shutting itself down. But I tried watching a 50 minute video on it and it lost 20%. So theoretically, it should have about 4 hrs of video playback capacity.
So my question is, will replacing the battery solve this problem? Or could the problem be something else? Cause I really don't wanna go out and buy a new battery for this, without being certain first.
Thank you all for your responses!

If the phone is working normally, the possible reason is battery or a bug in a management service of the battery. Make e full backup, do a factory reset and see again.

My sister had this problem before she handed this phone to me. I reformatted it as soon as I got it.
