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
wipe cache,battery stats try diffrent kernel

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 everyone
Just had a bit of a problem with my Desire HD. I had my alarm set to 7, it came on at 6. Then it wouldnt unlock. I pressed the power button to turn the screen on, the bottom buttons came on but the screen stayed blank. Then I had to take the battery out and put it back in to get back into it. Then I changed the SetCPU settings to go a bit higher when the screen is off because I thought that might have been the issue. They were set at 245MHz min and 500-something maximum when the screen was off. Now I have them set 200MHz higher on each.
Strangely, it also consumed 30% of the battery overnight which is really strange considering I only flashed this latest LeeDroid like 6 hours prior to it and only installed 1 application - Current Widget.
Is there something that can cause all these things to occur? Alarm coming on earlier than usual, huge battery consumption and no display?
I am currently calibrating the battery so could that have caused it? Unlikely I think but possible? By calibrating I mean deleting the battery file, draining it and charging it up again. Currently at 55% battery remaining.
Sorry about the long read
i have some strange issues with the batterij also,
have cleared the battery status (cwm in recovery)
but when i do a full charge on 25% the batterij drains as hell
maybe the battery is broke ?
recalibrate also not working
only standard widgets no apps
anyone any ideas ?
Have you ever tried wipe data/reset to factory in CWM? This is sometimes painful, but the last resort.
The first time I had similar experience was I upgraded from Coredroidroms 6.8 to 7.0 without fully wiping. All hell broke loose. Battery was drained in a record time. Eventually I had to do what was required to wipe all data.
If you flashed Leedroid cleanly but still had problems. Chances were these are hardware-related issues.

Hi, i'm running Paranoid Android 2.52 and since the last 5 days or so I've me experiencing the two following situations: the battery is fully charged, i start using the phone and it discharges normally, but when I load a heavier app it just shuts down suddenly with a low battery warning. the other situation is when i connect the phone to the wall charger after this issue, it starts charging normally but then it just jumps right to 100% with the same speed that it went down. Already checked the usage statistics but cant seem to find whats causing this, the battery just goes down abruptly.
Thoughts, anyone?
Try a different rom.. I recommend a Gingerbread rom with a kernel that supports battery calibration like Oxygen Rom. If there is no improvement after using the rom, calibrate the battery with this guide. http://forum.oxygen.im/viewtopic.php?id=723
If there is no difference, your battery is probably shot.
I've tried wiping the battery stats several times, re-flashing the rom, scripts and gapps, calibrating the battery and flashing rooted stock desire rom.
Is this method any diferent? I want to avoid moving to another rom if I can, i have tried several and i really like my current one.
EDIT: okey, I did as you suggested, flashed oxygen and followed the calibration steps. I was quite hard as the phone shut down as soon as the voltage level drop bellow 3201, but i managed. I experimented for a while on oxygen and the battery acted just the same as before. i have now reverted to jb, this time on AOKP v2.1. Is my battery ready for a replacement?
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.
Recently my N7(2013) will shut itself down when the battery is low (about 10%) without any warnings, not even the "Shutting Down" dialog that it should show whenever it shuts downs (except for the usual low batt warning when it reaches 15%). After the shutdown, I cant even turn it back on not even the screen, nor the low batt (waiting for charger) screen is showing up until I plug it into a power source the it will show the charging screen and then I can turn it on again.
Its been a few times now, not sure its a hardware or software problem though. It shouldnt shut down when it still has 10% in it right?
Attached is the screenshot of the Battery Usage that shows the battery level shots down to 0% immediately from 10%.
Nexus 7 2013, Stock, Not Rooted
Are you using a battery monitoring program (battery doctor, better battery stats, etc)? If so, look in their settings, to see if they are set to shut down @ 10%...

Nah I don't trust these apps so I don't use them. Moreover I'm did not root it so even if I use them they shouldnt have the permission to shut it down
Simple fix
It is an issue I have suffered with a couple of times and it appears we are not alone. It seems that the battery calibration is out of whack. When you charge your nexus up does it stay at 100% for quite a while? I
tried factory data resets amongst other things and nothing worked. I stumbled across a thread with a really simple fix. Turn your tablet off for 2 hours. Then turn it on again. Mine miraculously lost 26% of battery in that time (from 100% where it had been for 8 hours down to 74%). Then it started to use the battery at a normal rate. Working fine now.
Hello everyone! Recently my Note II started to behave differently. Whenever I charged it completely, the battery abruptly fell to sometimes 60% sometimes 40% immediately followed by low battery warning indication and shutting down. I tried changing ROM and calibrating the battery again but nothing worked. Finally I replaced the battery with a new one and also clean flashed another ROM in a hope to see if the problem is gone or still there. But to my surprise the problem is still intact. Now, when I turn on the phone the battery is 90% and when I keep using it, it drains normally, but as soon as I put it idle it turns off randomly. When I turn the phone back on the battery is still at the same percentage level at which is turns off. I believe there is not an issue with the battery. Please help me what to do, I am using TWRP recovery that doesn't gives the battery stats wipe option too. Should I flash a new ROM again? I would greatly appreciate if someone please helps me in sorting this problem.
What I have already done!
1. Replaced the battery
2. Changed the ROM
3. Re-calibrated the battery
