I dimmed my display some (still plenty bright), then undervolted processor by 50mv on each clock cycle and set governor to pegasusq (uses hot plugging to suspend the sceond core when not in use), then went through and debloated removing apps that i would never use, set my email to only check on 30 minutes. i am getting 15 to 18 hours now. Yeah am on a rooted phone

With my display brightness turned down pretty far which is still fine for inside use and on outside you can quickly change the brightness
(long press on the top notification bar then slight right or left to raise or lower brightness). I am getting very improved battery life. My screen only accounts for 29% of battery use which is less than the android OS at 33%.
I am still at 42% battery with being up and going with average use on web, messaging, phone and watching video) for almost 12 hours now. Yeah I will definitly say the screen brightness is the battery hog.

I am a battery whorr too and have taken pride in charging after long periods.

Lately I am accepting that my phone/plan is there to be used and if I do not use this resource it is being wasted.

You are paying for it so might as well use it and enjoy!

I like long battery life while actually using it. My time represents me using it normally doing web surfing, watching video, texts. calling etc.

That is a percentage which means I was doing other things that consume more power. I do run the display in the power save mode in the power save options on GA10. The biggest power use I have is actually WiFi. I changed the setting for that to allow it to sleep when the phone does and now I can easily go a couple days without charging.

Hey codegerm what kernel are you using and what script or program did you use to undervolt? I don't see the governor you mentioned?? I would like to try out your settings to see if i can get better battery life

Or... you know, you could search and get an extended battery for it.

I'm waiting for mine to come in on monday.

To undervolt I use Tegrak overclock which uses it's own controls as the kernel for GA10 doesn't support it directly. for sleep of the second core when not in use I believe On demand governor should do that, if not there is cpu sleeper dual core.

The extended battery is too fat, I don't like the way it makes the phone look.

This is great! This is not described in the user manual. Where else can I find tips like this?
