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.

I usually get android system usage at 1%, hence im freaking out. Help please! Could it be because i use vipernod, v6 supercharged and savagezen kernel?

I would say it could be any number of things, however the question is, what have you changed recently? Any updates, new apps?
Also, with this increase have you seen any decrease in your battery usage? I will have 70+% android usage sometimes but battery doesn't drain any faster. This is a normal thing for AOSP especially. Someone noted that they had high A.S. usage on a stock Nexus 4g.
This may just go away with a days usage, but be sure to check for partial wakelock. This option is in Spare Parts app not sure if its built in to MIUI. The wake lock is what kills your phone, when an app goes bonkers and keeps your phone awake.

True. Miui has updates every Friday. So yeah, i updates last Friday. I switched from tiamat to savagezen just so i can fix the high usage but to no avail. I can't check battery partial lock because miui has battery stats issues right now.

In addition to what imheroldman stated, charging your device will oftentimes cause your android system usage to spike, but 20% is nothing to be concerned with.

With ICS what is everyone using to figure out what apps aren't letting the phone sleep properly?
Spare Parts isn't working.
I've tried uninstalling about everything and I can't get this phone to sleep.
This is exactly the post I wanted to make today, glad I searched this one out.
I have few apps installed, and battery is going well for me. I'm a moderate user. I get about 20hours out of a charge.
I notice that even in airplane mode, my phone wakes up 3 or 4 or 5 times during the night for 5 or 10 minutes at a time it seems. What could this be? It's not data as I'm off wifi and in airplane mode. Any ideas?
Thanks all.
I've also been experiencing fairly high CPU awake times and was curious as to how I could track it down. Haven't found anything much yet in the way of apps, but I've turned off a lot of unnecessary Google syncing and an hourly sync of my Exchange account and it seems things are better now. I'm still getting awake times 1h30 greater than screen on time though.
I am seeing high "Keep Awake" times on Android OS Spare Parts force closes when I try to check Partial Wake usage so not 100% sure what this could be.
Wondering if this is the cause of some lower-end battery life we're seeing. My only thought would be LightFlow that is causing this (maybe to wake up for notifications). I thought I read it somewhere, but not sure if it was debunk'd or not.

I can't seem to get the battery results people are claiming. It seems like I lose 10 percent usage per hour during the day. I am starting to think I might need to replace my battery. Last night I left my phone unplugged and It drained over 25 percent with 7 hours sleep. When I installed the rom I used the wipe flag. I haven't touched a CPU controller cause it was suggested not to.
How do I find out exactly what is draining the battery so much?
I heard about battery calibration. I have read about a few techniques. I have also read that it is a placebo.
I am not sure what to do. Here are some screens. The drainage doesn't seem normal.

Battery life really depends on the user much moreso than the rom. are you constantly using gps? google location? Wifi? Facebook sync? Twitter sync? Google talk? Other im's thru social hub? max screen brightness? constantly receiving calls and texting?
All of these factors influence your battery life. its probably not the roms fault.

I am not saying its the rooms fault. I am trying to figure out what is causing the drain. I don't use social hub or the Facebook aphp. Only thing I kesync is Gmail, contacts, calander. Also, I use gtalk. I don't GPS at all.
Something is draing the battery.
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..
Sent from my PC36100 using xda premium
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

So a month ago I upgraded my epic 4g touch to stock rooted most current official release, and flashed the newest clock work mod... Not sure what kernel. And anyhow, after flashing it, basically my battery dropped in more than half.. After an hour of it sitting around I drop 30%. I even have greenify keeping my apps hibernated. Since I'm use to the s3, I'm not sure what to do.. Do I just flash a new kernel or what? Yes I did search and got nothing about battery drain after flashing an update.
Try the suggestions here-http://forum.xda-developers.com/showthread.php?t=2474084

Those are all common sense and app suggestions... This isn't an issue to be fixed with an app.. It's something going on.. Maybe the kernel

Most likely an app causing wakelocks that isn't allowing your phone to sleep. Look in Settings/About Phone to see what kernel you flashed.
I believe that your power drain issues are related to mine. Sometime in the last two months I found my battery draining about twice as fast. Upon investigation i found that nlpcollector was the culprit (google location services). After turning off google location services I found that my battery life went back to normal. I understand that this isn't an ideal fix, but hopefully it is temporary and google fixes nlpcollector so it isn't doing wakelocks like crazy.
