Im having a sudden battery issue with my G2 that started about 2 weeks ago. Im currently running 2.3.4 and have been for a while now. When using my phone at near full charge, it randomly shuts down. When it restarts it states I have less than 2% power and the red "x" is at the top. A few seconds later it shuts down again as it if it has no power. The only way to correct this is to remove the battery completely and reboot. Once I reboot, the battery level goes back to a normal state or it will read somewhere near 50%. Ive also noticed the following: the battery will charge VERY slowly. Sometimes overnight it still won't say fully charged. I've done the following to try to fix:
1. I replaced the battery with a brand new one. Same issues right off the bat.
2. Wiped my phone and reinstalled.
3. Checked to see if any APP was draining the battery or causing the issue. None are!
I've seen this issue reported by other G2 users on the Tmobile Support forum and none of them have gotten any solid results. I've browsed this forum some and couldn't find it either, unless i missed it.
Any help is appreciated!

Power down and charge 'til it thinks it's fully charged (should be a green light). If it doesn't show a green light (like you said, it won't fully charge), just leave it charge for a while (overnight would be good). Boot into recovery, either by booting Android + rebooting recovery or by rebooting recovery through bootloader, go to advanced and select wipe battery stats... I think CWM 5 still has this option (don't know about 4EXT)
zeppelinrox has a battery calibrator script which is useful and can automatically delete battery stats once fully charged... I can't find it though. I'll attach / PM it if you need it.
BTW I'm not sure if this is the problem, it could be hardware related. I'd try it though, it might help.
If all else fails and you're sure it's not a hardware problem, I'd do a factory reset and /or reflash ROM.

Thanks for the tip. I had already deleted the battery stats bin file from the system and rebooted and received the same results (assume thats what your fix does). I've also reinstalled the rom and had no issues. Ive done searches and found that SEVERAL other people with the G2 had this issue. Kind of surprised it hasnt yet been addressed on this forum. Back in 2011 Tmobile was asking for people to volunteer some info in order to fix it. Apparently nothing was ever done and when i call in (several times), no one seems to know what im talking about even when i point them in the direction of their own forums. I'm really at a loss and don't feel like paying out the a$$ for a new phone when I know this is not something I did.

hello mates,
I have rooted my htc desire and installed redux 1.2 ROM(gingerbread) with a ManU kernel...When charging the LED changes to green precisely at 90% (which i dont have a major problem with as it will go all the way to 100% if kept on charge)..also the phone will die at 10-15% of battery...I have read other threads regarding this same problem and am wondering if its a calibration error or is the problem with gingerbread ROMs as someone pointed out...Otherwise the battery is fine...and gives me a decent 1-2 days of use with moderate usage...its jus the problem abt the 15% n going dead which is a lil troublesome as the fone has died on me many a time for that last important msg, call or IM...any help appreciated...cheers..
That's not really a problem. The green LED at 90% is normal for android (try to fix it with battery calibration, helps sometimes) and the shutdown at 10-15% is also normal. Just take the last one how it is, all batteries are different. Some phones shut down at 5%, others at 20%.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
noticed this on ICS dev rom too but also had it on my old G1

You should try calibrating your battery for the 10-15% dying problem.
And as for the 90% LED changing to green, all AOSP ROMs do that, so no worries there
What worked for me was charging it while the phone is on, when the LED turns green, power it off and charge it again till it turns green.
Repeat this twice and then reboot.

This is to calibrate the battery. Some people find it useful to run a program called BatteryRepair, in my case I noticed a clear improvement on battery performance.
To avoid calibration problems with the battery, remember to unplug your phone when you flash a new rom!

Turning off at 15% of battery with Supernova 2.4 ROM
I am using Supernova Xtreme 2.4.0.0 ROM, and my phone turns off at 15% of battery. My battery is freshly calibrated and this problem did not occured with LeeDroid ROM and with the stock ROM neither. On the Droidzon page I have found some info in FAQ section, which says the following:
Question: Recently I let my battery go completely flat. When I switched my handset back on I was bombarded with forced close messages.
This has been reported once previously, but could not be reproduced under Sibere’s extensive testing under similiar conditions. For the same reason, unfortunately, we dont have a solution too. The OS is supposed to prevent a complete drain, and to shutdown at 15% and then 5%. The shutdown at 5% is supposed to be forced too. If it shutdowns, then this issue shouldnt occur. Data2SD depends on a normal shutdown to prevent data corruption. Once Data corruption has occured due to untidy shutdown, data is not unmounted cleanly, and then the issue can recur on every subsequent boot, which would require a complete reinstall.
So it seems to be normal, connected to the ROM, and NOT connected to my battery (it is calibrated).
My question is (which goes to Droidzone firstly), what should I do, if I want to use this ROM, but I do not want it to turn off at 15% rather I want it to turn off my phone at 2%?

I'm afraid this is not similiar to the issue in the FAQ. Your issue is that phone shutsdown at a level earlier than expected. The Data corruption issue is because the phone did not shutdown at the expected level and went down to as far as zero level of the battery, which resulted therefore in an untidy shutdown with no sync or clean unmount of data2sd partition, and hence ext4 errors. The 15% shutdown level is a normal soft shutdown prompt (which was missing in case of the issue reported by the user). The shutdown at 2% is the normal forced shutdown by OS.
As I said previously, your issue seems to be due to a poorly calibrated or defective battery, and it would help to do a calibration as per guides on XDA. If this fails, have the battery checked. To reiterate, it's not a rom issue and not something like a bug in the rom.
Thanks. So normally the phone with Supernova ROM should turn off at 15%. After that I have to be able to turn it on again, and use it till it drains to 2%, and shuts down finally.
For me it just shuts down at 15% and then when I switch it on and it boots up, the battery level shows 0% and it shuts down immediately.

No, a normal rom would popup a warning at 15%, asking the user to shutdown. If he doesnt, it would continue, and then give additional warnings, and finally do a forced shutdown at 2%. If it shutsdown before that forcibly, it's something peculiar to your hardware.
Ooops, so Supernova ROM should behave exactly the same way as a stock ROM (or any other) does in terms of warnings and shutdows.
I might try to do something with battery calibration. Should I do it before or after flashing Supernova? Or it does not matter? If I flash a new ROM, does it delete battery logs or it stays as it was before flashing?

Correct. For all intents and purposes, Supernova is exactly like a Stock rom. Difference is only in where internal apps are stored.
The so called calibration is just a file at /data, which means it will be wiped when you do a wipe for rom install.
[Update] Problem solved. I flashed UOT battery MOD after first boot (not before). Now it works perfectly.
A flashed the ROM again, did the battery calibration several times, but the phone keeps turning off at 15%. I checked battery voltages at different levels of battery, and I experienced that at 16% it is 3635 mV, then it turns off below 15%. When I turn it on, battery level is 0% and the voltage is 3390 mV, and when it is charged up to 1% it is 3723 mV, which is higher than it was at 16%. What is wrong here? Actually I use UOT kitchen battery MOD, can this confuse the system somehow?
Hi,
I'm running stock JB 4.1.1 (flashed the GSM version when it came out) on my gnex and as of recently, my phone doesn't charge over 72%. My battery history doesn't make any sense, it gives me the history of the last 20+ days, which is a bit useless. My battery life isn't bad, I get a full day of normal use. Just the stats are messed up.
Anybody ever experienced something similar or has a hint the problem is?
thx

If your phone is rooted you can do the battery recalibration from Cyanogenmods wiki (you don't need CM to do this):
1) Charge the device to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings » About device » Status » Battery Level = Full.)
2) Boot to recovery mode and delete the battery stats (in the advanced menu of clockworkmod's custom recovery). Keep charger plugged in.
3) Reboot the device immediately after wiping the battery stats and wait for [your system] to boot completely to the desktop. Once your entire boot is done and you have full access to the device, go ahead and pull the charger and continue with this troubleshooter.
4) Do not charge the device until after draining the battery completely, resulting in it automatically shutting off. Recharge the device completely and then use as you normally would.
Does this sound like what you are looking for or are you after something else?
Hi, I just bought a used galaxy tab s 10.5 and the battery jump from 20 to 99% in 20 minutes when charging . I started using it at 100% and it shuted down for low battery in 30minutes and I power it on again a it said 75%. How do you thinks is going on with the tablet? Thanks and sorry for my bad english.
Do you know if it's rooted and has a custom recovery. Clear cache and fix permissions in recovery mode
No root
It is not rooted and it have stock recovery. Is there an app to reset battery stats?

try booting stock recovery and do a factory reset.if that don't work than look into rooting it and TWRP so you'll have the option to flash something else or clear the cache and fix permissions
done
I did the factory reset and the permissions fix thrught TWRP but the battery still crazy. What more can I do?
I got the tablet down to 0% battery, to the point that it wouldn't turn on.
Took off the back cover using prying tools and then disconnected the battery, power cycled thrice by holding and releasing power button and then reconnected the battery and let it charge overnight to 100% and now battery life is amazing, don't have those drastic drops anymore.
There are no warranty stickers torn etc involved with doing this so you don't have to worry about voiding it. Just take your time and start at the microsd slot, open the hatch and work your way around slowly. Its difficult first time around because there is adhesive glue as well as clips holding it down. But still very doable without damaging anything.
Here is a link to a battery calibrator for root users
https://play.google.com/store/apps/details?id=com.vitula.batterycalibration
There are other calibration apps
Definitely other options before taking it apart [emoji111]
..
I tried with the battery calibration app and nothing. I leave you a screenshot , thats is WHITHOUT any charge, when it shuted out I just turn it on again. What is indexservice?
OK after ready the links below I believe a debloated ROM could solve your problem

I will try a debloated rom because son process called index service is draining the 60% of my battery, but is rare that the tablet shuted down and when I tried to turn in on and it shuted down immediately for low battery, but and enter in recovery mode and leave it on with max brightness and it stay awake for 4 hours!! Even when twrp said that is has only 1%.

Can you post a full screenshot of your battery settings. You just posted the graph. Not sure about the index service, but knox drains battery too.
Had the same issue crop up on mine. Did the the battery 0% drain then recharge a few times. And factory format. Now it just randomly keeps restarting (even when on charge now). Called Samsung and they have sent a pack to post it to them to sort I hope.
Now with the debloated rom the crazy battery drops have stop but I'm having random restarts. What's is happening now?
I know it's a lot of work and getting frustrating but let's try Odin back to stock .

Now with stock rom I still having random restarts and battery drops. I dont know what more to do and I dont have warranty.
I leave it all night on plugged in the charger and it didn't restart but when I started using it, it freezes up and restart.
Now it sounds like a kernel issue .I really dislike that cortex chip to
So, a few things: First, I used Sunshine on my phone last Wednesday to put the newest T-Mobile firmware on my phone. Prior to doing these two things, this problem did not exist. I am on ViperOne 3.5, chose T-Mobile as my carrier and was very careful in setting things up.
First two or so times I would notice my phone was not waking up, so I held down the power button to restart and after it turned on there was a very large battery drain (30-50%). After this I decided that maybe the firmware was the issue, so I fastboot flashed a fullwipe version through fastboot (originally I had done a no wipe flash) and restored backup nandroid from TWRP. After that the problem persisted, so I thought maybe it was a rom conflict and did a clean install of Viper 3.5, thought everything would be good but while in the car it did it again. This time I caught it quick (I had used my phone maybe five minutes before and when I restarted the battery drain was less than 5%. But seeing as I've done a clean install of both the firmware and the rom now, I'm sort of at a loss for what to do.
Has anyone heard of this, or would anyone have tips on what to do? Can provide additional info if needed, just want to get this worked out. I've been lucky so far and it's done it while I didn't need power. If it were to do it during work when I can't check the phone for a while, it could lead to the entire battery being depleted.
::EDIT:: I should also add that this happened once when I was asleep, and I found that the phone would not charge when in this state, as the orange light was not on when I woke up and I had to reboot the phone. Again, extremely weird and it only started after Sunshine and firmware change, nothing else.
This "sleep of death" thing has happened to me a few times, though I have not seen the battery drain. I have not figured out what is causing it.

I actually just caught it and tested some more out. Tried plugging it into a wall and it won't charge. Also tried plugging it into a computer and it will not recognize. The only two things I have changed are the firmware version, and running sunshine through it. I'm actually pretty worried since it won't even interface with a computer until rebooted. Also went from 90ish% to 77 in a matter of 15 or so minutes
A long time ago for an unexplained reason my phone froze at 17%. It hold more power then that, but Android is frozen at that number. When the device is off and I first plug it in then it only shows 17%.
It's been like this for a year. I've done various things, like factory reset. Tried draining and fully charging battery many times. No luck. I was told I should get the battery replaced. I may still do that.
I just recently installed twms. I noticed it actually has the proper battery %. What is making twms check different then Android?
I have the last version of Android for pixel 3 xl. My phone is rooted but I don't have any mods installed. Is there something I can do to have Android read the battery the same way that twms does? Would a new kernel fix this? Please point me in the right direction?
I do not know what Twms is but it seems something wrong with rom itself. Did you tried wiping everything and clean flash stock rom ? Maybe some files gets corrupted.
Also can you try any battery app that report battery voltage ? If it is reported correctly at least you can say battery is ok..

I am having the same problem as you, only in my case I am stuck at 1% when I restart in TWRP if it shows me the correct percentage, I have tried with different roms (custom - stock) and different kernels I still have the same problem.
I have noticed that when accessing the root of the system (any rom) in the address or path "sys/class/power_supply/battery" and I open the "battery" file with a text editor there if I see the real value of the load of my battery
