[Q] G2 Battery Life Issue

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.

What killed my battery?

What the heck killed my battery? This is with the extended battery and I started from a full charge after flashing a new rom and clearing battery stats..
I turned off all connections, and turned off sync.. Sat the phone down and went to bed after about an hour of web surfing.. I went to bed with 70% left and woke up 6 hours later with 37%...

Its all in the last screenshot. Keep awake time is huge. That's the bug if I had to guess.

That keep awake time is normal, nothing strange there...
Your story of browseing for an hour then going to sleep for 6 hours doesnt match your batteries' graph.
According to your story, there should have been a sharp decline from browsing web since the screen would be sucking the power, then a very slight decline from being idle, something was either running in the background (facebook maybe, it has a high % of usage) who knows?

Yeah idk.. If you look at when wifi was on that was when I was browsing.. Then after that there is a steep decline which doesn't make sense to me.. I don't think it was Facebook or anything because all data/sync was off...
I know it takes a day or two for a new rom to settle in but I certainly wouldn't think it would have that large of an impact

I read somewhere that there is/was a bug where after a reboot Google talk or maybe google+ launches the camera in the background which keeps running until you manually open the camera app and close it. I believe I read it some where on Franco's kernel post. Not sure if the bug is still there and if it's the culprit here, but might be worth investigating.

Weird battery activity

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.

This has happened since GB. it happens when you reboot and phone was not fully charged. Bug has been around for awhile

Seems like a FC24 problem. I ODIN'd FC24 modem on my phone. Overnight the battery went "out", the phone shut down and the phone heated up. When I booted it back up the battery meter went up, like you guys.
I just ended up going back to EL29. No problems. I'm on AOKP though, so things may be different in some respects.

Don't you WANT a higher "system" usage than anything else? That means apps aren't sucking much battery.
I mean, if everything else is using so little battery (WiFi, screen, apps) what is left for the remaining percentage besides the system?

Not really.
I had this happen yesterday. It wasn't that the others were using so little power. It was that the power used by everything else was dwarfed by the power used by Android System. In just under two hours my phone had dropped to 85%. When I looked I saw that Android System had used 45% of that. The phone was not sleeping even when the screen was off. I could also see that the Stay Awake time of Android system was nearly 100% of the time I had been on battery. Something in the Android System was stuck in a wake lock.
I tried to determine what the process was that was hung up but I was unable to do so.
I rebooted the phone and the wake lock went away.
