Hello all,
Before some days I came back to GB from ICS and my "Android System" drains much battery. I installed mexdroid and I changed to elitemod to see if it is mexdroid's problem, but I got the same problem with elitemod. (After 4~ hours discharging with 2-3 calls and 15 minutes play game only, I got 60% battery.) Does anyone know what is going on? Thank you.

Well, you could order a new battery for next to nothing and see if that helps. If not, try flashing a new kernel. I had a battery drain issue on a gb rom before i went to ics. I have had amazing battery life with ics.

Remember that every time you flash a new ROM, you need to do a couple battery cycles in order for the battery meter to recalibrate. Charge the phone to 100% (leave it on the charger for a while to make sure its really full) then use normally until about 10 or 20% (don't drain to zero, as this is not good for Li ion batteries). Repeat a couple times. Your battery meter is not accurate until you do this.
Thank you I will try this and I will report back to tell you if the problem exists
I usually let the battery drain until its almost dead before charging right after flashing a rom.
Yes you should definitely charge to 100 and let it drain to dead. That will calibrate it. Then just charge it back up.

Everytime my phone reaches 10%, the phone will shut down itself and it won't turn on again.
i have tried bump charging and calibrating the battery but still without success... anyone got any soulutions other then buying a new battery?
thanks.
Try this: fully charge the phone then let the battery drain completely, until the phone shuts down. Plug the phone into the wall charger, let it charge for a minute or so then turn the phone on while still plugged into the charger and let it charge completely. After a full (100%) charge, the battery indicator should be precise.
I've noticed that if i restart the phone of plug it in after charging, the battery indicator will show an extra 10%, so that's the main reason for the shutdown at or a little below 10%.
This operation should be repeated once a month, just to keep the battery and the battery stats fresh.
Don't wipe battery stats and don't try any other calibration tweaks. They might damage the battery. There are some people here complaining about that.
If the phone still shuts down at 10% after the above-indicated trick, then your battery might be old and in need of replacing, but i wouldn't replace it just because of a 10% indicator error if it can still hold a proper charge.
I have the same problem. I also calibrated my batterie and everything but it still turns off at ~10%.
But since I know that, it's not really a problem
Its always turned off at ~15% for me. I accepted that this was normal. I've seen a lot of posts around but no one seems to of found a proper solution. I actually doubt that there is a proper solution to this.
Punched in..
snq's kernel? I take it is normal with it as none of the GB sense rom managed to come even near the 1-2%. A bug with the kernel probably.
Flashed Oxygen last week - bam, phone turns off at 1%. No calibration was needed even .
Every time this happens to me I charge it 100% then I reset battery stats. Then let it discharge threw normal use then give it a proper charge, plugged into wall charger, not PC.....! And once its 100% ignore green light check it says 100% on the top bar then I unplug. Its normally always sorted then. But I have had to repeat twice in the past.
I also agree about kernal, often after updates it goes bonkers, and I'm on miui, lots of updates

Mine also used to turn off at ~14%. After using a battery calibrator, i could push it down to 7%. However, on the other "side" of the scale, it goes down qute quickly from 100% to ~92%. All this on GV2.8, and the unofficial ManU kernel 2.1.1.

Just wipe battery stats in recovery after full discharge if you changed ROM, and then let it charge to 100%.
Used the battery calibrator app (for nexus one) with detailed instructions. Now batt lifeis awesome, turns off at 3%.

I had the same issue on my stock Telstra branded rom. Since changing to cyanogenmod it hasn't happened since.

Did the thread move or die, or is the link just wrong?
Lately my phone will go through a massive drain until it hits around 55% then it will drain normally. I have not changed anything since this started. Any suggestions? I'm thinking I may need to calibrate my battery.

That sounds like a good idea for your situation.

Thanks for your input. I want to wait a few days before I do it. So it will give it time to see if that really is the problem. This only happened yesterday and today so maybe tomorrow will be better. Besides the only time I really have to do it is later this week.

How does one calibrate a battery? Is this the same thing as "conditioning?"

You charge your battery to 100%, wipe batterystats.bin, then run the battery down to 0%, then charge uninterrupted back up to 100%
Battery Calibration does it help ?
I have a similar situation and i followed the battery re-calibration method too but still didnt help.
Situation - The battery would charge till 88% but will show its fully charged. Recently put Vivokat so now its even more prominent. Every reboot drops the battery by steps, like i would reboot and the battery would go from 80 to 65 just like that, no gradual decline or anything. And even after a full charge (the green light indicator is on) still the battery would continue charging.
Tried - I tried resetting the batterystats.bin file as suggested, fully charged till 100% then removed batterystats.bin file then allowed to discharge all the way then charged continuously till 100%. No outcome
Anything else that can be done ?
Hello. I'm using CM7 nightly 256. And I have a problem with battery percentage indication.
I put my phone to charge at night and in the morning it have 81% of battery (number is varying. someday it stops on 65% and someday at 79%). But if I reboot the phone it's on 99%. How can I fix it?
Same problem on Rem_Puzzle_Rom V2.43!Phone charges very very very.........very slow or stops at 80 or 85%.
Errrr, maybe it's the charger.

If I remember correctly someone mentioned a long time ago he had sent his back to HTC and they said it was a mobo fault which can't be fixed by flashing, it does seem to be affecting a lot more people nowadays tho.

From the past one month or so I am having this weird issue with my phone's battery. The battery drops straight from 20% to 1% and the phone switches off. This last time, I connected the charger before the phone switched off ( a matter of few seconds ) and the battery jumped straight to 21%. Is my battery terminally damaged or is it a software issue? I have attached a screenshot of the battery discharge graph available in settings menu.
Also, I faced the insufficient memory problem and I have repaired the phone about 2 months back using PC companion to ICS 4.0.4. I have been using the phone for about 15 months as of today.
Thanks.
hmmm maybe you charge your phone from pc? if you do this the battery will never get fully charged really...that i can say from my personal experiance.
By the way just charge the phone as much you can also let it charge on 100% and reboot it(battery lvl must go lower than 100) do this till you get a reboot with 100%...
If those do not help your battery is damaged you maybe have banding issues,3g/wrong baseband,forground apps? maybe a combo of all this.
Had the same issue, cured after repairing on SEUS.
Quite a fluctuate on the graph.

Maybe try to recalibrate battery!
Same issue, on mk16a. The battery is weird, if I leave CWM running it last for more than one hour, but androids jumps from 20% 1% or 0% suddenly. Also when booting again (after the shutdown) it's reports 20% but again it drops...
I'm on CM10 but i think this happens also on stock ICS.
Battery calibration don't work...tested it 2 times
Any hints?

Hi guys
recently i bought new battery because my old one used to jump
from 70% to 100% and had really bad battery life.
i replaced the battery and calibrated it and i noticed that the 20% from 100% to 80% goes down realy fast
should i recaibrate the battery?
what should i do? thanks!
It depends on the rom u r using.
All roms except stock based roms have this problem.

Im using aosp by maclaw studios
the weird thing is that the 70% acts like it 100% and im having really good battery life
from 70%
Its a problem in sumsung charge system.
In custom roms when u full charge battery it is about 80 % charged.

I think you should charge it when the phone is turned off. I noticed that my phone tells me it is "Charged" when it is turned on. However the actual percentage in Go Power Master is 80%.
Sent from my GT-Xperia S using xda app-developers app
so it has nothing to do with the battery quality and the battery calibration?
the problem will not appear in the stock rom?
Thats if needed. To check if the battery is fully charged, try these step.
1. Charge the when it is running until it says "Charged".
2. Turn off the phone and keep the charger plugged in.
3. The battery image will appear. If it is not full, wait till it full. When it shows 100% then it is fully charged.
Note that powering up the phone takes some significant amount of battery. If the battery is still draining fast. Calibrate may be needed.

enchanced rom shows 100 percent but still shows charging. So I guess it fully charges
Well the battery level seems to be jumping unusually from time to time . What i do is i wipe the battery stats from cwm , i leave it over night to fully charge without doing anything to it , calibrate the battery with `battery calibration` from playstore , full discharge and full charge again . I do this after each rom that i flash and it seems to do good and seems to point the right amount. Anyway the charge lasts as i hope it lasts , from 1 day if i do stuff with it like some wifi , some messaging , many minutes of calls .... to about 3 days if i do only calls. Cheers
