my battery was down to 11%, so i turned my phone off and charged it for about 60 seconds through USB and now that i turned it back on it says 47%! there's no way it could have charged that quickly. this is on cm 6.1.2
i flash a lot of different roms but wipe data, cache, and dalvik before each new one. i don't run any unusual apps that would drain my battery and i have tried wiping battery stats every once in a while. ive also tried charging techniques such as charge for 8hrs, charge for another hour, etc. and nothing seems to work. my battery will drain in about 4 hours of moderate use (just web browsing and google talk while watching TV). im in an okay signal area, not using any 4g - happens with any rom.
this is a launch day evo battery but the actual phone (was 002) is replaced with my current 003 refurb.
im gonna try to wipe the whole sdcard and start from complete scratch.

i had this problem and when i checked to see what all was running i saw Google Maps was running... I didnt turn it on either but with a force stop and reboot im back to normal.
wiped sdcard completely, repartitioned, flashed latest cm 7 nightly, used for a while, charged to 50%, unplugged and in 20 minutes went from 50% down to 31%. had the same sort of behavior before on all roms. just display, cell standby, and android system using battery - not much else. maybe i need a new battery?

what pri and nv version are you on? that could be the cause.
hi there! right now im on cm7 110822 boot179-4 nightly (for 5 days now), and yesterday my phone started to drain the battery extremely fast, it took for 12 hours to go from 100% to 12%, and i usually have at least 50% after 12 hours. and i noticed something. when i touch the screen and hold, it tingles. is it possible that my touchscreen got screwed up and there flows way more current on it than it should? oh and one more thing. my phone has been extremely hot in the last day, the battery reached 45°C, while usually its around 35-37...

somebody help me, please!

The tingles thingies must come from settings - sound - heptic feedback. Getting hot must come from installed 3rd party apps that continuesly having your 3G data line access none stop. Trace back your history of installed apps to see which one actually doing the dirty spy job in your phone background..
Also making sure GPS and WIFI is off when not using and data sync too if you worried about continues syncing.
Mine normally after full charged, it will only drop 5% after like 8 hours from night to morning.

no, its not because of haptic feedback, i can tell the difference. wifi or 2g/3g is constantly on, depending on where i am, but it never caused any problems. gps is almost never on. i have used these apps for a month now, neither has caused any issues yet. i already solved the high temperature by disabling the boot oc (i accidentally forgot to do that after flash), and its possible that the tingling was a placebo, but the battery drain is still present. i will try the 110830 nightly, heard it was good. but thx for trying to help!

Even if the apps already there for months doesn't mean they're not giving you problem. Some apps start creating problem after an update that its developer might overlook. Another possibility is your battery may at it end of life..
If you have backup of your current rom right before it giving you problem, it might be good restoring it to narrow down your headache..

its finally stabalized with bluetooth working, it gets decent battery, great performance, great features, you can add wind kernel 2.0 RC1 to improve battery life if you want.
so far no bugs, haven't tried mhl yet it has never worked on CM for this phone as far as i know though so prob still down, will report back later when i get a chance to try it.
with the said setup above i'm getting roughly 3 hours of video playback on 200 brightness (with wind kernel) when the test is done i can post exact numbers
3h 13m on 200 brightness running video playback
the results are posted on page 46 of wind kernel thread.
http://forum.xda-developers.com/showthread.php?t=2119976&page=46
It is incredibly stable too. I haven't had a crash, reboot, SoD or BSOD yet.
What is the best configuration kernel for this rom with wind 2.0rc1?
my phone is P936
Just stopping by to agree, since the RC2 release (I'm running nightly 5/11, day after RC2 release), my Bluetooth connections are working, my battery life is better and I haven't had to pull the battery to reset since.
ive had the odd random reboot now, not horrible though. the only other issue i'm getting is oddly high battery pull from WIFI but if i turn off wifi it's it's fine, i'm trying to figure out how to fix it now will report back, i can currently get 7-10 hours out of the phone with moderate use if i turn off wifi, i still think the battery can be better but it's workable for now.
the wifi issue worked itself out after some time, i'm getting 9-14 hours of use right now once i get a good setup i'll post it with some stats

I can tell you that on the 5/15 nightly and wind 2.0.1 I am getting that WiFi wake lock issue again. I reverted back to 5/14 and it went away.

im getting good battery life on 16/17 nightlies, yesterday i got 14 hours out of a battery and i even did a few extra things like 1 hour of gps navigation (had screen off) but it still used 25% of my battery (google maps said that in battery info)
anything over 12 hours i consider good.
There is a weird bug onde the CM kernel for RC2 that may prevent charging when the battery is depleted and the phone is off.
Installing the latest wind kernel fixes that problem
Sent from my Nexus 4 using xda app-developers app
i actually learned about this today it happened to me, and it doesn't prevent charging, just the battery screen doesn't show up so you think its not charging, also you have to let it charge for 5-15 min then pull the battery, then power up the phone unplugged to get it to turn back on. i learned the hard way.
Maybe it was a coincidence and my battery just died, but I left the phone charging for 2h and the battery just didn't work.
I will check with another one to make sure
pull the battery, put the battery back in, plug it in for 15 minutes, then unplug, pull the battery again, put it back in, then boot ur phone and charge it while on.
it was probably already frozen when u left it charging, if the above doesn't work then u might have to look into more serious methods like trying other batteries or seeing if you can get into download mode to flash a new kdz and start from scratch (if u think the rom is causing it)
Can confirm good behavior of CM10.1 RC2 and Wind Kernel 2.0.1. BT is working.

The problem was the battery got to a very low voltage level, that it needed external charging, having it jolted from another source it started working again

Hey Guys,
Woke up this morning to my G2 out of battery life, due to getting home late and forgetting to charge it.
I plugged it in and turned it on, as I usually do in this situation. When it started up it, everything seemed fine until it got into the Rom, and it immediately powered itself off (not abruptly, it came on with this usual "powering off" message that happens when it runs out of battery life.
I assumed this was because I hadn't charged it enough. So I let it sit for a couple of hours on the charger. Tried it again after that and the same thing happened, and has been happening all day since then. The strange thing about this is that the Recovery and HBOOT seem to work fine, so it can't just be the battery that's causing this.
I wiped the phone, and installed a new rom. Still the problem persists. And I still have no issues going into Recovery. It's only the actual OS that doesn't work.
Any thoughts?
Have you done any undervolting?
Skickat från min g2 via Tapatalk
Any undervolting wouldn't be present after a full wipe but you may not be getting a full wipe
Use a superwipe script and or fastboot wipe and try flashing a new ROM again

Hey guys, figured I'd see if anyone else has had this happen to them or if there's a fix or really. Is something wrong with my phone...
Flashed PA at about 85-90%. Left my phone alone for awhile and decided to flash DH's GPE. After flashing, running aroma installer and such, when I booted back up, I noticed my battery drained significantly. It drained all the way to about 45%. From at least 85% to 45% in one flash and reboot. Obviously this isn't normal. Is this common for these phones to have such a severe drop in battery? Is it a hardware issue or ROM issue?
I installed Xposed, ran GravityBox and changed some features that required a reboot. Rebooted and battery only dropped about 1%.
Any ideas?

usually takes 3 or 4 charging cycles for you to get a true idea of battery consumption.
I wouldn't pay too much attention to what it was showing straight after you flashed....
