1. Use CPU spy to check deep sleep.
2. Use betterbatterystats to check what running behind.
3. Use greenify to fully control your app activities.
Good luck mate.

Sounds like you have a rouge app. Download system monitor and see what one it is! Then uninstall it or change the sync settings!

Better battery stats is a good app.

That's a lot. I bet a few are eating up the battery.
Watchdog will watch your active apps and alert you when any particular app breaks through a preset % CPU threshhold... I use it and it works great...
ill try both of those apps . Here are some screenshots if you guys can think of anything else. Thanks

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

Jedi Knight burning background battery

Just flashed Jedi Knight and my battery is draining when phone is sleeping at about 5% every 30 minutes. No CPU Sleeper app loaded just the ROM sleeping. Any ideas?

Look at the battery process what draining it-_-
Sent from my SGH-T989 using xda app-developers app
67% screen with it on auto brightness. Misc apps drawing less than 4%.
Sent from my SGH-T989 using xda app-developers app
You just flash it today? Why don't you give the rom a couple battery cycles
Sent from my SGH-T989 using xda premium
The light sensors are draining with auto brightness
Sent from my SGH-T989 using xda app-developers app
it's not the auto brightness. I'm using jedi knight with auto brightness and I get <1 % drop per hour of standby time.
it's probably an app that's causing wakelocks. download Better battery stats and check the "partial wakelocks" tab
I'm using the same ROM and I've noticed the same thing. So far I haven't been able to pin down what is draining it while sleeping either. I'll try better battery and see if it tells me anything new. Thx

Holy Kernel Wakelock Batman!

Noticed some battery drain on my G3. Then saw this. What the hell!
CPU states are normal.
Help very much appreciated. Thanks

You may want to download wakelock detector from the play store to see exactly what app/process is causing wakelocks.
Yeah use wake lock detector for some reason better battery stats doesn't work correctly with this phone

Thanks guys. I'm probably being an idiot, but how do I know which specific app is causing the wakelock?
