[G2 General] polaric:
The G2 has a fantastic battery already, why not make it even better?

I like to see how far I can push this phone's battery. In no way does that mean that you need too as well, but for those of you that do want a few more hours or another day, I'm happy to share what I've learned.

After I've spent time learning the quirks of this phone, and most of its respective ROMs, I've come up with quite a few tricks for improving battery life, some specific to this phone, some just in android general. I now get average 3-4 days battery life, when I use the phone quite often during the day all day long.

It is your personal preference on how much of android's background services that you use compared to apps. This is only suggestions for the users that want to improve battery life.

Heres some of the simplest questions you can ask yourself when you go through the settings center:

Do I really need this feature enabled? Do I use it often? Even if I do occasionaly use it, is it that much of a pain to just turn on when I need it?

Do I really need GPS on 24/7? How often do I really use GPS?

How many apps do I need running in the background?

Do I need to keep autobright on, or keep the screen super bright?

That being said, here are some of the simple things that Ive done.

I keep everything off unless I use it every day.

I keep GPS off 24/7, I never use it.

Out of habit, I always close all apps.

I keep autobright off and keep the screen on 14 brightness. Unless Im right outside in the sun its easy to see, and if I am I can just turn it up with the quick setting.

Some of the more advanced stuff I do, that completely varies on your ROM:

Go through all the system apps and freeze anything you dont use. Example being the Picasa uploader (for me at least).

Leave as little system services running as you need. You wouldent believe how many unneeded services android runs. On the stock roms there are TWO location daemons running.

Currently Im using CleanROM, I switch between it and Cyanogen about once a week, just cant make up my mind on stability v. features, but on CleanROM, some of the stuff I have currently froze

Nearly anything involving Verizon, the carrier APKs are massive bloatware.

I disabled a lot of google services, some people may rely on these, personally I dont, the biggest two google apps I use are chrome and Gmail.

If your on a stock based ROM, disable the LG services you dont use. Textlink wastes a huge amount of power, as does QSlide.

(This applies alot more to carrier based roms than it does Cyanogen/AOSP, but even they do have a few unneccesary servcices.) Be careful when you are touching system services, if you dont know what one does, a google on its function is helpful.

Use a different launcher. Excluding the stock google launcher, most factory launchers are very inefficient, LG Home is no exception. Personally, I use SmartLauncher, a very light and very nice looking launcher with a fantastic layout. Nova I know is very light on resources aswell.

The more widgets you have cluttering your screen, the more power they will waste.

I can personally confirm myself that Kitkat based roms have incredible battery life after they settle in for a few days, the kernel level improvements brought with KitKat are very noticable. Currently Gummy Rom and three CM11 builds exist for KitKat, why not give them a try?

If you have unusually high battery usage, check your wakelocks, and see what exactly is using all the power, and you can disable/turn it off and remove that battery drain.

On a final note, comeon guys turn your phones off at night. I have yet to hear a good reason to leave it running over night, all it does is waste power and most commonly let the notification light run for 8 hours. If you use your phone as a alarm, you could turn on airplain mode overnight.

These are just some of the things that I do, if you have any more suggestions, feel free to post them or message me, I'll be glad to add them to the list.
