Sorry, I can't post in the ROM thread yet. Just wondering if I need to calibrate the battery every time I pull the battery. I ask because I use a wall charger for my batteries.
I have three that I rotate so I always have a fresh one with me. I feel a lot better letting the wall charger do the work so its one less thing the EVO has to do. No wear and tear on the port too.
If anyone has any idea I would appreciate it.
Thanks, Che
No, you just need to calibrate the battery each time you flash the rom; pulling the battery is fine.
Thanks. Wasn't sure if it needed to be done for each battery every time since they are different ages and have limited lifespans.
I've been doing it every time and have been getting amazing battery life. Could be the new ROM too.

I use to calibrate the battery as well until I read heard about by wiping it doesn't do anything... Correct me if I'm wrong.. just throwing that out there..

To be honest, I'm not 100% on what exactly happens during battery calibration.
I thought it was something done to the phone; how it saw the limits of the battery; and not something done to the battery it self.
Any one who knows a little more about it feel free to correct me.
WITH CALIBRATION

flash the cm-snap kernel, charge and then calibrate your battery
IIRC, that is normal for Cyanogen. It cuts normal battery usage so much that the display eats more than the rest of the phone together. Hence, the biggest battery moocher becomes the screen, not because it eats more power, but because its competition eats much much less.

no cm does not have the snap kernel. to calibrate the battery you charge it to 100% and then wipe your battery stats from recovery. this should take care of most peoples battery issues.
but i dont see your problem. almost 13hr unplugged is very good for this particular phone.
For the past couple of weeks ive been having issues with the battery life on my G2. I used to get 12+ hours of battery life on it but now im only getting about 7 or 8. Ive tried recalibrating the battery, clearing the dalvik cache, and changing settings on certain apps but that hasnt seemed to make a difference. Ive noticed that at the end of the day, the android system takes up a huge chunk of my battery. Any ideas?

I've had the same issues as the builds of CM have gotten higher in numbers. The ROM that's given me the longest life is the stoock Gingerbread rooted ROM. I switched back to CM because oof the Text MMS & them always being Slideshow issues as well as no ability to stoop the phone from vibrating when I'm on a call. Same issue with CM too actually.
I'm bumping this because I feel your pain.
you can fix that in call settings you know!
Are you running CM7? If you are, open up spare parts and look at the battery information under Partial Wake. See if there's something tying up the system.
There are a few things listed but I dont think its anything that would eat a whole lot of battery. Should I be looking for something in specific?
Anything that's more than a sliver is eating the battery and keeping your phone from sleeping.
I'm getting 24 plus hours on glite which is aosp also. Maybe the battery is finally giving up the ghost. They do have a finite amount if charge cycles. If nothing else has changed and all things being equal to your 12 hour charge cycles maybe you could try a different battery.
So I charge my phone all night, take it off the charger to go to work at 6am by 3pm my battery is at about 8 percent. Here is where it gets funny, if I turn the phone off then back on I have about 59%. How does that happen

Sorcery. That's how.
I'm guessing the reason your battery gets drained so quickly is because of the poor network coverage.
Could you also provide a screenshot of the apps/programs/hardware that have drained your battery? By that I mean the screen you see after hitting battery under settings.
The fact that it goes up so much after a reboot is very weird indeed. It usually happens the other way around with mine, the battery level drops about 15% for me after a reboot, which I also find weird.
I have had the same expierence with my phone as well. Dont understand it either.
I suggest you use a battery calibration app or s-off/root and install Clockwork Mod recovery to clear your battery stats and run a few cycles. Your phone doesn't know where full is and can't detect it as well as we'd like.

I think you need a battery calibration. Before i calibrated mine would drop 10-15% sometimes but now it is good. I would also add expect a small margin of error if you were using your phone heavily and it is warm/hot and you reboot. Some people report, myself included, that you might see a slight spike after your phone cools down.

at least you won't do anything harmful wiping stats, so perform it
I have an GS3 Sprint SPH-L710 using liquid smooth ROM, my battery life don't really last me all day, but whenever my phone is getting to 19-14% it goes completely dead, have anybody had/has the same problem and know a solution for it?

Yep. Use a Touchwiz ROM. Or if your attached to the ROM try using a battery calibrator.

I thought battery calibrating was a myth haha .
I had this problem before as well and switching OS's between TW and AOSP didn't help.
If your screen is flickering at around 15% and then your device cuts out, it also indicates the battery is gone for good.
I'd suggest getting a new OEM battery or go for a third party company like Gorilla Gadgets or iAnker Tech.
But flashing a TW ROM is other worth your shot as well if it'll fix it
