Here is my setup for battery life..

Scott was gonna post in thread...but I will..

This will double or triple ur battery easy...

My setup i use for battery are all things i have learned from trial and error...

I am NO expert or anything like that...i have spent countless hours researching and trying different things...

On average i get 2+ days on a full charge....thats with 4-5 Hours of screen on time....and 1+ hours of phone calls

and usually 1-2 hours of Sirius Xm app running..

I accept NO Responsibility if ANY harm is done to ur phone..

Please use this setup at ur own Risk!

I have a whole setup to get my battery life like this..

First things you will need are...greenify,,,,and greenify donation package...its $3

but worth every penny...you HAVE to have the donation package so you

can greenify system apps....which are what Drain battery on 4.4.2

You will also need xposed installed....wakelock detector is used to see whats killing ur battery

and it works with greenify...when you see something that is killing ur battery you can just click it and then greenify

YOu will need to check almost all the expermintal features....all of them if they apply or you want..

I check everything in Expermental features except the Phoney one and the GCM push..

if u need these checked then check them..

Greenify is something you can play with and try different things with...

Other apps you will need are BetterBatteryStats....this is a great app...very detailed..

Will give you great info on wakelocks...IMO you need both BetterBatteryStats and Wakelock Detector

I also use LUX....paid version is worth it...the free version just doesnt work as well..

WIth LUX i gained another prolly 30 mins of screen on time...

Also Get app ops module from xposed..

Install and then go into ur settings...it will be under ur application manager..

Open and on the first screen you will see google play service..click it

The scroll all the way to bottom....you will see wake...turn that off..

Only the wake and ONLY on google play services

That's it...

Now this is a super power app....so be careful

I have been doing some trial and error with it and i have also turned Android System "wake" to off

as well....and no ill effects yet after a week..but do this at ur own risk

Here is a good little read on battery life!

Now also if ya can change ur email settings to every 2 hours if possible to sync...I leave them on manual sync only

and i turn on when needed...

Also if u can turn ur sounds down...like all ur keypad sounds and all that..wakelock "1013" are ur sounds wakelock

these will kill battery...and vibrations will as well..

Will save a ton of battery....I don't mean like ur ringer volume...leave that and notifications up...lol

Also when u get greenify there is a widget button..has greenify symbol with 3 zzz put it on ur home screen

And push it anytime ur done using ur phone...to hibernate any apps u have been using..

Oh and here is another link for good battery info

Now greenify Everything you can that ur phone doesnt need to run or that you dont need

all the time to be running...

Evertything google....Except Google Play services...app ops with help with google play services

Greenify Play Store...google search....google +...

Now if u dont use Google Now(google search) just freeze it in Titanium Backup and google +

These are HUGE battery killers..

Again though these are things you can play with....what works on one phone wont another..

So little trial and error is need...

Another thing i think is a MUST....is to calibrate ur battery...

You should do this everytime you flash a new rom..

There are battery calibration app that are great....BUT

WIth hyperdrive there is one built in and its great....

See post #3 for commands..

But i charge to 100% then wait an additional 20mins

Leave phone plugged in and open terminal emulator....type su

and then accept prompt..

then type bc

Calibrator will open...select auto calibrate..

Let it do its thing....phone will reboot....remember to leave plugged in..

after phone reboots....unplug phone and run till FULLY Discharged..do not plug phone in or turn off

Just let phone battery run all the way down till phone shutsdown then recharge..

I truely hope this helps everyone out as much as it has helped me...

I have helped alot of ppl double and even triple there battery life with this..

I have answered around 200 PMs over last month or two and everyone has mostly had

great results with this setup..
