Hello,
I've been having strange issues with battery lately, the problems started after installing CyanogenMod 11.0 by ADC-Team - Release 11. It seems that battery charges normally to 100% (by android's builtin battery meter) and power drain is normal when phone is not in use. But for example, browsing web drains the battery to 0% in something like 15 minutes.
I completely wiped the phone with TWRP advanced wipe options and installed newest CyanogenMod 11.0 by ADC-Team - Release 12 but the problem is still there. I tried app called Battery Calibration which should create new batterystats.bin file (I don't know what this actually does and how that file is supposed to work). App says I have to push "battery calibration" when app shows battery is 100%. I have done this couple times but it's not helping. App's battery status also does not match the system builtin battery meter. Apps battery meter keeps rising when builtin battery status shows full. Should I do the calibration multiple times or try to do it differently?
battery.PNG shows battery usege history, here you can see how the power is lost suddenly
battery_calibration.PNG shows the app I tried to calibrate the battery with, when I took the screenshot app said battery charge was 56% but builtin battery meter showed that battery was fully charged.

Hi everyone,
I am having strange battery issues. When the phone is switched on and charging, it charges very quickly (an hour or so). But it also discharges just as quickly - I talk on the phone for 30 minutes, and battery indicator is already on 3/4th green. Maximum time I can get out of it is 15-16 hours standby, and normal calling.
However, if I switch off the phone and charge, it takes longer to charge it (around 2-2.5 hours), but it also retains the charge longer. Maximum time I can get here is 35 hours standby, again with normal calling.
Also, my indicator is quite weird - when my battery information (in *#*#4636#*#*) says 34%, the indicator still shows 1/2 green.
I had done a "wipe battery stats" only once, when I had upgraded from EPF21B to FRF50. I have since tried CyanogenMod, and updated from nand backup, then went to FRF72 etc., but I have never done "wipe battery stats" at that time. Could this be the cause of my problem?
I realise this may be a battery calibration issue, and I have read many threads, but I am unable to find the authoritative way to re-calibrate my battery. Please help.

a few days ago i flashed stock jvs. and applied cf root.
now i'm facing some weird things. battery lasts only like 12h. and when i go to battery stats in "about phone" the "on battery" time says things like 1min, but the longer the phone is on, it gets longer, like 2h ...
today i tried to fully load it and wipe battery stats.
didn't work,
now i've applied semaphore. and still shows weird things. and it doesn't seem as if the battery would last longer.
didn't find a thread with this problem, only the "official" battery bug, when the percentage changes within an hour about 20% a higher...
maybe so knows?
When you say wipe battery stats, did you do the entire battery calibration procedure? I find it's most effective to wipe and charge phone overnight while it's off (Like the first charge you do when you first get the phone)
i did the calibration like it is said in another thread:
fully load battery,
go to recovery, let it plugged in for further 5-10min
unplug,
wipe battery stats
reboot and let the battery be drained until it turns off automaticly.
but still confusing...
never had this befor, on stock 2.3.4 and cfroot, normal information like 2d 3h ... etc.
Hey guys I just picked up the Thrill the other day, and like others I've realized the battery life is horrible on this phone not to mention when I reboot the phone would take a 10-15% out of the battery. Coming from an Atrix I decided to try the battery fix for the Atrix since it worked for me in the past, well after following all the steps in the guide it seems my phone reports the battery more accurate and battery life is better but your mileage will vary. Reboot doesn't take 10-15% out of the batter percentage either so here is the guide and link to the original thread, all credits go to xploited.
PS.. I followed all the steps except for flashing the jug6ernaut's CWM battery fix since it is for gingerbread roms
Link:http://forum.xda-developers.com/showthread.php?t=1198333
Guide:
Standart disclaimer: I am not responsible if you break things by following this guide, though I will be genuinely surprised if you do.
Credits: This fix is a combination of battery management techniques discussed in the Atrix forums + a technique that I originally found in a Milestone forum (I didn't invent it, but I am too lazy to search who originally posted it ).
This worked in fixing the problem for me (the same problem that I see many others are writing about on the forums), but I can't guarantee it will work for you.
Who should use this? (aka your battery problem symptoms are
1. Battery life on 2.3.4 is significantly worse for you than before.
2. Battery stats are jumping and showing inconsistent information.
3. Your phone loses 30%-60% just by sitting there overnight.
4. Phone idle draining 30%-60% of battery just by sitting there overnight.
5. After flashing a couple of roms, your battery stats got messed up and the phone thinks it's at 100% charge while it's not.
I personally started having battery problems after flashing a couple of roms, applying 1% battery mod and despite flashing jug6ernaut's CWM battery fix.
When I went to bed with a 100% charge, I would wake up to a 50% charge, with Phone Idle process showing up as massacring the battery. The steps below successfully fixed the problem for me.
Prerequisites:
1. Atrix on one of the rooted 2.3.4 roms (ideally,- deodexed and with unlocked CWM)
2. Wall Charger
3. jug6ernaut's CWM battery fix (put it on your SD card you will need it later!) I have also attached it to this post.
4. Battery Calibration app from the market
5. Watchdog Lite or Full from the market
Instructions:
It's best to complete this procedure in the evening before going to bed, so you can leave it at 100% overnight and check in the morning if the drainage issue is fixed!!!
The whole procedure along with recalibration might take up to 5-6 hours!
1. Take the case off your Atrix (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. (Explanatory pic, needed number circled in red). Write it down.
My Atrix was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%. Back when I used a Milestone, it usually showed 60% after doing this.
10. Let it sit there charging for 2-3 hours.
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours, turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Install jug6ernaut's CWM battery fix (even if you had it installed before), do not reboot yet.
Do not disconnect it from the charger still!
13. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
14. When the phone turns on, go into BatteryCalibration app again and look up your MV numbers
- if you were like me, they should be significantly higher than before. After this whole process I had 4200MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
15. Before going to sleep - Install Watchdog from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
16. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
17. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.
(Your general battery capacity should have increased, even if something still was draining the battery, you will be able to find the infringing process in WatchDog with the settings we've set up in step 15 )

Not a bad process. I did something similar. Main part is Watchdog and finding out what's draining your battery. On my phone the infringing process is "Suspend". Now, if there were an app that was keeping my phone from suspending and running up the process it would be an easy fix but unfortunately the process with the highest "partial wake" battling my "Suspend" is the "dialer" so unfortunate I'm just gonna have to wait for GB since I have no interest in Rooting or installing roms at this point.
I'll give this a go. Thank you

Hi guys,
Since last week my Ace battery react very weird, it drains from 100 to 10 in just few hours. Currently im on Meizu ROM. (Previous ROMs: Democracy, MiUi, Nightly)
I have applied many tweaks to save battery life but all went in vain.
Guys please suggest me for this situation.
Thanks,
Swapnil
Change ROM and try..If its still not working, get a new battery
Controversies,controversies everywhere :what:
Already changed the ROM from democracy to Meizu, but problem still persist.
Is there any tweak to save my battery apart from the new battery option?
Thanks,
Swapnil
check if something prevents your device from entering deep sleep. (background processes)
then charge your battery, wait till its full (till you get notification in setting, that is isnt charging anymore)
=>
use the hell out of you battery, till completly depleted and phone shuts down.
=>
recharge battery, wait till you get notification that its full => keep charging for some hours. (best way to do this is to charge overnight.)
might work...or not. just try it.
Check whether the battery is swollen or not
If swollen replace it immidiately
This only could be the problem

Is this a new ROM that you just switched to? I had faced a similar issue when I switched to one of the ROMs. Thankfully it wasn't a batter issue. Let your battery reach 100%, go to CWM recovery, in advanced select wipe battery statistics, do not charge the battery till the battery goes to 0 and the phone dies. Check after that. You can check your battery health by dialling *#*#4636#*#* and going into battery information
Hi,
Thanks all of you for your reply, the problem is somewhat resolved.
I have wiped out battery status, installed the batterybinstat apk and its worked for me. Now my battery last for 1 day with wifi on.
Thanks,
Swapnil
Hello,
I have this problem for a while, where my battery percentage suddenly drops to 0% causing my phone to shut down. When I boot it up again it says 1%, or shuts down right before my login screen appears. After booting it a few times it will say the *real* percentage again, which is usually around 40%. I could also skip the multiple reboots by plugging the charger in before booting causing it to also display the original percentage.
I have tried recalibrating the battery a few times (by using an app that removes a file that stores the battery percentages), but unfortunately that did not help. I've included a picture of my battery statistics which show how my battery percentage changes.
Thanks for reading .
It means you have dead battery for, good luck ?
