Just got home from school to find my phone on 34%. It went from 100% to 34% in 5 hours. When I saw it was 34% I looked up in disbelief, when I looked down it was on ****ing 22%. (12% down in a fraction of a second) I decided to restart it to maybe get the battery to display the right percentage, but when I booted up I got the 30 seconds until shutdown warning because the battery was drained. What gives? Anyone have issues like this?
Calibrate battery.
Discharge completely until it doesn't even boot.
Having the phone off, let it charge completely.
Once charged, turn it on at let it still connected to power socket for 10m.
Disconnect from power and you're done.
If this doesn't help, then factory reset. Or install a battery monitor app to track app drain.

Can you charge phone? Try factory reset, if reset not help and problem persists go to service center

Just charged it to 100% again. Gonna do the calibration thing before factory reset though.
hmmm same isssues

Is this normal. I did try and do a search in my defence.
Yes. It is like that by design. It stops charging at around 95-98%. Its to prevent you from overcharging the battery.

This is a known issue. You can try and reset battery stats in cwm when your battery is charged and/or emptied. It works for some and not for others. I haven't noticed my battery lasting any less when my battery doesn't "charge" past 97%
There have been some discussion on this. I get about 97% myself. From what I've read you may get full charge if you let it drain all the way. I don't do that myself. Very happy with battery life as is.
I used to get 100% before I switched to the Vegan rom.

Either let it drain until it shuts off a few times and then charge it all the way up or if that doesn't work, use CWM to delete the battery stats when it's at 95% (full, with a GREEN light - not charging, with a red light) and then let it drain until it shuts off on it's own.
I did this a long time ago (delete the stats) and it's been perfect since. Charges to 100% and does indeed show battery at almost empty before it shuts off.
Good Luck.
Still no go here but it can get tom 96%... lol
I am sitting a 98% with VEGAn.
I am now having an issue where u can use the device, then I turn it off, and
turn it on the next morning and see about 5 to 10% of my battery was drained.
Confirmed Fix
Confirmed fix for me on Vegan 5.1. Letting battery drain down to zero and shutoff the tablet... reached 100% on next charge. Now the indicator charges to 100% every time.
tried this and still no luck . still get to 95-6% bugger
Vegan here..this is how I fixed it:
1) Drain it till it shuts off, try restarting it a few time to make sure its dead.
2) Once dead, plug it in, boot into clockworkx, and reset battery status (do this quickly)
3) restart, and leave plugged in idling till fully charged
4) use and enjoy a accurate battery level!!

You have to remember that in order to install some apps out there, you have to give them permission to use the internet and to interact with your device autonomously. I have found a few apps that were pulling my tablet out of sleep mode and turning on the wireless to download ads or other updates, and that (along with the length of time to shut back down) was affecting my battery life.
I would say to go back and review what you've installed, and to also check your screen timeout settings. Just doing that saved me quite a bit of overnight battery loss.

Last night I left the house with about 40% left on my battery. By the time I went home, my Sensation was completely drained. This was within 3 hours, which should not drain it to 0%, especially since it was asleep most of the time.
When I got home and I plugged it in, I booted it up and surprisingly, it booted up with 42%. Before plugging in it had no power left, and the phone wouldn't boot at all. I wiped my battery stats yesterday morning too, after charging it to 100% for a few hours.
Seems like my battery stats are VERY wrong right now, and I just wiped it again after charging it to 100% and leaving it there for a while. Does anyone else have this problem? I know some people are having random stats popping up here and there, but this still had 30% juice left before it just died out. Never happened before. I was able to nearly fully drain it just 3 days ago too (100-5%).
Charge to full, wipe again, and drain to about 5%. Charge full and repeat. It usually takes a few cycles to correct battery stats.

I'd also recommend this application from the market for battery calibration, although you need root.

Alright, thanks, I'll try that. Hopefully it gives me an accurate reading
weird situation?
ok so yesturday i flashed over the new humble.
and well i left it charging iver night.
when i woke up my i disconnected the charger and took off.
when i checked my battery stat and what was using it.
my display was at 49%
i have never had it this low its always 75% and up.
and during the time.i had it down in the 40s. it hardly wasted any battery.
and now i restarted my phone and screen is back to 89% -.-
and i havent used it at all and ita been 4 hours and am down to 88% battery only with phon at idle in my pocket. ohh and i had data off..
wat is going on!?
You need to calibrate your battery. The easiest way to do it is to use the battery calibration app you can get from the Market. Put it on the charger and wait until it is 100%, and before you unplug it, run the calibration app and press the button. After it's done, take it off the charger. For best results, you need to then completely drain the phone without ever plugging it back in and then completely recharge it again without ever unplugging it. However, just doing the initial calibration will help you out a lot.
what do u mean the initial calibration?
and do u know why my display was really low? n stayed like that?
untill i rebooted
So, I wanted to calibrate my battery today, and so I charged it to 100%, turned it off and charged it to 100% again, then booted into cwr, wiped battery stats, restarted my phone. After a couple minutes I remembered to unplug my charger.
About an hour later off the charger, my phone went from about 70% battery to 0% and shut off automatically. I knew there was no way I actually ran it down all the way that fast, so I rebooted, and it showed it was at 4%. A couple minutes later it jumped up to 15%, and has been jumping back and forth for the past few hours.
I think I messed up the battery stats by keeping the phone on the charger after wiping the stats. How do I go about fixing it?
The only thing I can think of at the moment is running my phone until it actually dies, then charging to 100% while off, then wiping stats while actually unplugged. Will this work? Or, is there another solution?

Im just guessing but maybe wipe cache along with the battery stats and try to re calibrate from there. Did the battery get really hot, like over heat?
I would just cycle it complete and see what happens. I've had some screwy numbers show up during a calibration before. I wish I'd taken a screenshot of the time it dropped to 50%, fell instantly to 25%, then slowly rose to about 42% before it started falling again. It was freaky. Once the full cycle was done, it didn't do it again.
Hello, not sure if this is the right page to request this type of help but here's the deal: the last few days I've been having a sudden crazy battery drain... I cleared the cache, then performed a factory reset and the battery was still draining - around 1.5% per minute with the screen on. Around 1% every 3-4 minutes with the screen off. I read an article about Safe Mode.. and before I got into Safe Mode I had 23% battery... when I got into Safe Mode.. it showed me 62%. I got back into "normal" mode and it still showed 62... now it's currently at 60%. Thought this is weird.. any idea what's going on?
Either bad calibration or a dying battery. Do a full cycle (run it till it's dead then charge it to full before booting). If you still experience problems you should probably get the battery replaced.

Any idea what might have caused the bad calibration?
It seems to be ok for now.. It hasn't discharged yet.. will let it turn off on 0 battery and then charge it full. Thanks.
Calibration can go out if you regularly charge it when it's not empty yet. Modern batteries dont have as many problems with memory, but it's still possible.
