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?
Hello,
I have a problem with my flo battery. As i said in the thread title, the battery stays at 100% for more than 7 hours, even if I play with it, and have more than 45 minutes of screen on.
When it reaches 30-35%, it goes off, like it has 0 battery left in reality.
So, does anyone know what could be causing this reporting error?
I have tried 3 different roms so far, but the problem remains.
As far as I remember, the problem appeared along with 4.4. I did not encountered this in 4.3.
Sounds like you need to calibrate your battery if it's not being reported correctly. Follow the instructions in this app https://play.google.com/store/apps/details?id=com.nema.batterycalibration

I have tried this the first time the problem appeared, but no luck..
First sorry for the translation, I'm from Brazil and I'm using translator ok.
I come here asking for help to you to solve a major problem that is plaguing me, and the next have a galaxy tab 3, SM-T210 model, the following is happening and the battery meter this crazy carry the tablet 100% off when I turn on 10 minutes on the battery drops 1% to% the tablet works well for hours, and placed on standby screen off the meter starts back until you reach 100% and so continues the meter is completely crazy, already tried everything restored original factory hard reset, I root already used the battery calibration, practically already tried everything porfavor count on help from you to solve this problem, I'm waiting thanks.
Same problem here. Changed battery and problem remains.
I can use it with 1% for hours, seems some problem with battery meter. I'm about to flash a custom rom / bootloader/ recover from scratch wiping all to see if it helps.
Otherwise I'll need to use it at 1% forever
-----------
Edit 1:
Absurd! Seems this device forgot the low battery level...
Replaced battery, flashed another stock clean rom with latest version (4.4.2)
This "drain" also happens on recovery screen.
It works with 1% during hours... I' ll try to let it drain all (wait it to really discharge all) and recharge 100% again.
-----------
Edit 2:
Haha, went to recovery right after post last update, then it increased from 1% to 100% without the charger
Seems something is messing up with the battery levels on android OS on all versions. I'll let it discharge on recovery... at least seems it is the correct level... let's see if the device learns again the battery levels
-------
Solved: removed battery, hold power button for 30 seconds (to clear all energy accumulated on circuit (capacitors?!) and plugged it again. Worked.
I read about it on some google search.
Dear hugo_prado

Hi, Its simple Install Battery Calibration app from Play store https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=enand perform calibration. It will reset battery stats data. Reboot. Tell whether this has solved ur issue or not.

No need to wait till 100%. Press that and change it to calibrate any time. Now go ahead with calibration. All the best.
Battery Problem
Guys
I updated my GD to 4.4.4 CM11 and everything is working ok except for one detail.
I carry my cell phone and start using normal, if not shut down or restart, but if I turn off or restart
sometimes ends when rebooting the battery for example was 74% back to 39%.
This has happened to me a few times, i already reinstalled the ROM, calibrated the battery but the problem remains.
Do you have any experience or story about this behavior?

May be you are using an old battery. My phones old battery used to get reduced by 10-15% whenever i used to remove my battery. Since the new battery im not facing this issue
