Android OS stays awake and kills my battery - LG Nitro HD

So I have unbricked my phone and have flashed cm9 and fullthrottle now I'm on the official ics from att. My phone has been dying quickly. I checked my battery stats and seen android OS in my number 2 spot. Today I unplugged my phone and didn't use it for two hrs and it went down 5% I checked and android os stayed away 1 hr and 53 mins.

Same thing on my end. LG really screwed this up.

You need to install the better battery stats app and see which app is giving you wake locks.

Yep, install better battery stat, it's even free for XDA member, search the app forum.

Also, there's a thread called "known identified battery drainers" in the ATT GS2/I777 forums that has some good, universal stuff on interpreting wakelocks.

any luck solving this?

I tried flashing this from 3 times wiping everything and still get the android os taking most of my battery. I tried better battery stats but can really interpret it. I don't have facebook link or instagram. I'll post pics of better battery stats.

Did you flash through CWM or using LG's official tool from a computer?

O flashed through CWM

I'd suggest disabling stock apps you don't need, I guess. Most people seem to think the battery life on that ROM is decent.

I always disable the att apps that come with the stock from. I get about 10 hrs on medium use with the extended battery. If this was fixed then I would get way more

same issue
I never even thought to check into that as I have also had bad battery life, but figured it was just the nitro. New to rooting LG's as I had samsungs before. I am having the same exact issue running OH!NO! Full Throttle 7.1 and never realized it.. Is it just settings that are not allowing it to sleep?

I have no clue but there is something that is keeping the phone awake and not letting gp to sleep which is really hurting the battery life

i definitely recommend getting juice defender. it made a HUGE difference in my battery life.

I tried it but it didn't help much just turned off the data. The only thing that really helped was to go into app settings and disable android and it has helped some

I have the same issue. Android OS is (or was) the best battery killer. AT&T support person told me to do factory reset AND DO NOT INSTALL any app that are not preinstalled. I have to install them later one by one to find one incompatible with ICS.
After reset operation (happened 2 hours before) I have now Screen as the best battery killer Battery went from 77% down to 62% with some browsing and preinstalled apps update. It looks promising...

Battery ideas?

So I'm running a 2100 m a h extended life battery and I know I should be getting better life than this. I'm running 4.1 jelly bean on cdma phone, stock kernel. I also have the app killer checked on, and my screen brightness is pretty low. I've been having my wifi at home but still for 4 hours in 40 percent screen time that's really bad numbers. just wondering if anybody has any input

Uninstall your task killer, those do more harm than good. And download BetterBatteryStats to see what is draining your battery.
More likely it's your apps that are causing it to drain very badly. Any shady looking apps I would uninstall. And like above me, do those both as well.

What setting is this? And don't use it.
You may want to use the Better Battery stats application to check for wake locks.
Trying a different kernel may also help. The Faux kernel works well for myself.
Lastly, the standby time doesn't give as much insight into your battery life as well as screen on time does. What kind of screen on time are you getting?
Note: don't use task killers, and don't manually kill applications.

Wow your right. First for some reason I couldn't even click back on x d a developers app kept force closing and after I check that I can finally go back didn't think that would effect so much

Turn off any app killing, as you've done.
In your screenshot, you had a lot of calls, that'll do it too, so battery life can vary.
Here is today's. I don't get it. 2100 math battery low brightness display

Why is task killing worse than good?
Sent from my SPH-D710 using xda app-developers app
I am not sure about the stock app killer but any 3rd party app killer is constantly scanning your phone looking for apps running even if there is none so it's constantly using battery power

Does battery calibration make a difference?!

As many of you know there's a battery calibration app to use after flashing roms to wipe battery stats and improve battery. Sometimes I use it sometimes I don't... Just wondering if it actually made a big difference but I can never tell. Just thought I'd ask

In my personal experience with the nexus one, htc desire and now the t989, it makes no difference that I can notice
No. It's snake oil.

The battery stats file is essentially a log of what is using your battery. It has no effect on the performance of your battery.

My battery

Im having battery issues. After searching through the forums I havent found anything like it. The android system is eating my battery. Tried factory reset, flashed Csrom, nothing. Any suggestions? Please and thank you.

Get better battery stats free on xda. Just Google it. It will show you what's really keeping your phone awake. Here is a photo of my partial wakelock caused by picasa syncing with my gallery. Picasa is Samsung bloat I guess but I froze it with titanium and now I'm getting great battery life.

It ended up lowering down after I came out of the shower. Thanks for your help though.

Google search question

Since updating to job I for the life of me cannot figure out how to search on Google search bar and make it a specific time or date like I did in ICS. Anyone know how to do this?

Guess I'll add this also. What would cause my battery to say I've only been on my phone 6 hours even though its been like 9 hours?

Try installing Better Battery Stats off the play store to see what is causing your battery drain. The search problem I have no idea as Im not on stock..

Tried searching nothing worked.

Quick question guys anyway to disable the low battery popup and sound completely. With my zerolemon battery my once my battery hits 15% the popup warning starts but the funny thing is this battery last so long that it takes me 10 to 20 hours depending on usage to get it to 1% so the popups drive me nuts. Please help.
My ROM is dandroid 4.7 android premium 4.1.2 with koot kernel.

I'm not running this ROM at the moment, so I could be wrong, but is it not in settings/display/battery notifications? I know that particular ROM is heavily debloated, so it might have been removed.
I've checked everywhere and I guess its been de bloated cause I can't see it anywhere.

battery notifications
Do you have the pop up notifications found in display settings unchecked? I'm running this as well thats the only setting I'm aware of relating to battery notifications. I havent had my battery drain down that low yet to see if it still beeps yet since its only been a couple days.

Haha good one. Just the basic greenify and the use of app quarantine to stop the stuff I don't use. This zerolemon 7000mah battery is just insane. With the stock battery I was charging it every 8 to 10 hours of use.
