Currently on "Next Launcher" Awesome launcher I will say...
Battery Life is Awesome..
40% or 13 + hours with heavy usage as I post...
In addition, using Weather Widgets, Clock Widgets, Calendar... and misc running in the background...
Now, review your Apps...you may probably have a Battery Sucking App you need to remove...
Go with your gut with recent Apps you flashed your culprit is there..
Remove one at a time...watch your phone performance then start adding them back again watching your phone performance...
That Battery Sucker is there...
Its Bubba
