battery charging/draining too quickly

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?

[Q] Phone randomly shuts off

Up until this morning after work, I had been using Synergy. On practically a daily basis, my phone would shut off randomly in the middle of use. Sometimes, I wouldn't even be using my phone. I had noticed my battery draining much quicker and Display would have the biggest impact. I could shut my screen off, check my phone ten minutes later and the battery will have drained another 5 to 10 percent.
This morning, I flashed MikG after reading it's one of the more stable Gingerbread ROMs that implements things I like about Sense 3.0. I went out to lunch and my phone randomly shut off when it said I had 84% capacity left on my battery. Every time this happens, I have to go into recovery and with cache and dalvik cache or I get random force closes. When I finally get back into the ROM, it shows 0% battery. At this point, I hook my phone up to a charger, wipe cache and dalvik cache and reboot my phone. When it got back into the ROM on the charger, it registered 87% capacity.
I'm not sure what could be causing these random shutdowns. I'm using radio 2.15.00.05.02, PRI 1.77_003, NV 1.90_003.

Random shutoffs
Your problems your describing are pretty broad and could be a result of many factors. Could be a kernel issue, not wiping phone properly, or a corrupt download of the rom. Plus your radio is way out of date, will effect you internet speed. I was on synergy and I know there was a lot of complaints on bad downloads. I would recommend starting over on a clean slate to isolate the problem.
1. restore nandroid
2. Install Amon Ra 2.3 recovery (if you dont have)
3. Update radios/wimax/etc.
4. Copy SD card to hardrive on computer
5. wipe phone in recovery minimum 3 times
6. Partion SD card 0/2048/ext 3
7. Flash synergy RSL1 zip in recovery (non God-mode recommended)
8. Flash Dark Tremors A2SD in recovery
9. Reboot phone let settle
10. Boot into recovery
11. Flash kernel (lithids freedom v.0.9) or new custom kernel out called sol
12. Calibrate battery
Do these steps and you won't have any problems

Sorry to hear you are having these issues but a fellow board member tried to help you and I understand you may be busy but a quick thanks I will check that out would of been nice.... Also there is a thread dedicated to your issue with quite a few post. Look here and I hope it helps you as well as what was advised above.
Not trying to be a @ss but people get mad when no-one answers them and this is something that with a lil searching you would of seen there were plenty of threads about and possible solutions. Good luck and I hope your issue gets resolved

I work nights and I haven't checked this thread since before I left for work at 6 last night.
Whenever I perform wipes, I wipe cache and dalvik a minimum of three times. Whenever I flash a new ROM, I wipe data a minimum of three times. I'll update my radio and see if I'm still having problems.

My phone doesn't randomly reboot, it randomly shuts off. It doesn't restart, it just shuts off.

You have a battery issue and for $15 on ebay you can fix it.

I bought one of those GaliliO batteries off eBay. This is my first day using it, but I'm already liking the results.

Battery issue

After using odin to go back to ec05 and returning to srf 1.2, everything was pretty stable and I am pretty happy with the result. Today I had something strange happen, I booted up voltage controll and it said it was asking for super user rights like it always does except it was just hanging there thinking. Also my albums in my picture gallery would not load. So I held the power button down and chose the reboot button not the turn off. When it booted back up my battery said it only had 5% left, before reboot I had 35%. So what the heck, why would it do that.

First, did u update super user in market, and then go into super user app and update the binary?

Its an improper display if you boot into cwm and wipe battery stats it would have showed the proper battery also next time you charge your phone play with it once it reaches 100% and leave it on the charger for an extra 20-40 minutes and then you battery should be back to normal. Side note get off of froyo where no longer in the dark ages bud

It is a bug that has been reported hundreds of times. Plug into a charger and reboot back to where you were or leave battery out for 5 minutes and reboot. Wish people could search for this but know the search function is not great.

Yeah, but that is not the OPs issue. There is a bug in CWM and the battery stats that when you reboot below a certain percantage...let's say 70, it will incorrectly drop to a very low percentage. This is easily avoided by rebooting connected to a charger or can be resolved by removing the battery for a few minutes. It will go back to where it was. All the wiping and recalibrating in the world will not resolve this bug. It is just a glitch.

[Q] Battery Charging Issues.

Okay, I currently run CM10, about a week ago I flashed another developers version of CM10, and started having battery percentage reporting issues while charging, So I flashed back to the original ROM, formatted, cleaned battery stats and for some reason the battery will charge up to like 75-80% and stop reporting the correct percentage until I reboot the phone, even when back on the old ROM, I am using simonssimons34 ION kernel, which running it before with the old ROM, reported fine, so I don't think it has anything to do with the kernel.
I have almost always let this battery deplete to about 1-2% before a charge, and never over charged it, so I am a little annoyed that my battery stats are mis-reporting now until I reboot. Is there any fix for this? Or do I need to try another ROM or something? It only reports incorrectly while recharging, it depletes normally and never has issues with that.

This happens to me every day. Learn to live with it.

You can clear battery stats in recovery. There's also a few root apps that let you do this. (search for clear battery stats)
It'll take a while for it to rebuild accurate battery stats, but it sounds like at the moment any fresh stats is better than what you have now.

You can try calibrate with this app:

I've laready tried as both of you have suggested before, and it hasn't helped me yet, I did it two ways I did battery wipe in recovery, and through a 3rd party app, but the phone still wants to stop reporting the correct percentage until I reboot my phone.
And I even tried letting hte phone completely deplete after wiping battery stats, and it's still wonky ='(.

Ugh this is soooo annoying ffs, anyone ever had any luck on fixing this issue? I've tried:
Flashing two different ROM's, nothing
Charging, rebooting wiping stats, calibrating, draining to 0, rebooting, nothing
Using calibration apps
None of this has worked for me what so ever, the only thing that seems to work is rebooting after the phone has stopped reporting then it will show 99% then charged.
What I don't get is it will charge to 100% if the phones off, but if it's on the phone reports an incorrect percentage, wth?
I am about to try a full RUU reflash and see if that will fix it, but that's a last resort. HELP PLEASE!

[Q] Is my battery dead? Or is there another problem?

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?

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
