After I flashed latest firmware my device booted and then suddenly turned off and battery dropped to 2%.
Any solution for this? Is my battery dead?
same for me, happened once from 60% to 6%
try to calibrate your battery
as for me, I'm using L-Speed for calibrating. No problem so far.
If still happen, then maybe your battery is damage

Sometimes battery drops suddenly. Charge it again and see how fast it charges. If it charges completely in few minutes then battery is fine. Also about the calibration. I really don't think you need battery calibration if you are using latest custom roms. It updates battery stats itself on rebooting.

When I first got my Captivate, the battery life was pretty good. I was able to get about 13 hours while only draining 10% of the battery in standby mode. However, I recently had the battery drain completely until the phone turned off by itself, and I recharged it to full while having the phone turned off.
I thought that would improve the battery life based on what I've read, but it hasn't. The battery life has gotten worse! Now, I only get a little more than 5.5 hours for 10% battery life in standby mode.
What should I do to get the battery performance back to where it was originally? Should I do another full cycle charge with the battery depleted and charging it while the phone is off? Or should I let the battery get close to depleted and charge it to full while leaving the phone on? What's the correct process for cycle charging?
BTW, I'm not rooted, and everything is stock with the exception of LauncherPro. But I was already using LauncherPro when the battery life was good.
Hi there
i bet this is the 1290312 thread about batteries but i can't find the one that suits me.
so here is the deal with my alfs06 and gingerdx021 x8: when i am charging my phone, the percentage goes high reeealy fast. when it reaches 99% it stays there for a while (30min) and after that it is completely charged.
i was thinking that i have a problem with battery calibration, but i fully charged my battery and then deleted battery stats in CWM, but still no result. what do you guys suggest?
fact: if my battery display is, let's say 16%, if i reboot my phone it goes to 19%.
after batterystat wipe you must charge the battery 3 4 times to calibrate it. it will takes a while.
thanks for your reply. i will charge it and post after a few days if the issue persists.
Hi,
With all applications closed, data/wifi/gps/sync all turned off and no screen usage my phone went from 100% to 19% overnight (roughly 8 hours). I did this as a test after my phone would randomly throughout the day drop by large percentages.
Prior to running testing the battery overnight I put it to charge, and I found that it charged from ~20% to 100% in only an hour, which I believe is abnormally fast.
I am on the stock ROM with the stock kernel and no other applications installed.
What might be the cause of this?
Could this be a software issue (ie: software stopping the charge early or the displayed battery percentage being off)? Or is this likely to be the hardware?
Thank you for your help!
Try completely draining the battery then charging it with no powering on ( just plug it in then dont touch it) for 5+ hours

many causes are possible, however most obvious one is rampant wakelock called baseband_xmm. no definite solution, although custom kernels have dealt somewhat with it.

I have stock ROM (JB India version). I noticed similar trend a few days ago. I had done factory reset and subsequent to that, battery loss overnight is less than 1%.
You could try the same.

i have a similar problem :/
@rudders93 @zri best you can do now is to install betterbatterystats. it will tell if anything is keeping your phone cpu on.
Thanks so much for the replies!
As suggested, I found that completely draining the battery and then charging the phone while it's off resolved the issue
Hi guys I've a problem with the battery drain irrespective of the ROM I use. The battery discharges normally from 100 to 29 %. Then their is a sudden drop from 29% to 15%. Wiping the battery stats hasn't helped. Also if I allow the phone to automatically switch off and then I plug it in to charge and then allow the phone to charge upto 2 or 3% and then reboot the phone, the battery percentage after the phone reboots will have jumped to 33%. Any solution to get this faulty battery stats corrected?
It's a really frustrating problem. Any solutions plz.
What ROM did you use? If its MM based, try to use wakelock detector and amplify battery extender
My battery has been dying at 20-30% lately. I've done all the tests from cycling (letting it completely die, then charging to 100%), to battery calibrations, full restore, full system wipe in TWRP to the point where it says "no OS installed", and then flashing the stock rom.
After all this, in just the first try, the phone died at 30%! I turned the phone back on immediately and saw that it showed 3% remaining. I decided to leave the phone on and let it discharge on its own. After 24 hours, I was surprised to see that the phone was still on and at 1%! That's a 2% drop in 24 hours. I've attached the battery usage page for reference.
Can anybody explain what is going on here?? Is this a software or a battery issue? I'm left to thinking it's a battery issue after all of the tests that I've done. Whatever miscalibration it has should have been reset when doing a full wipe right?
What's battery waster?

It's a good app used to drain battery for cycling purposes.
