Turn “Off” most of the services to save on battery life.
We bought an Android Phone with the current version “kitKat” this late May 2014 and found that this Android beast eats battery power. I check the internet for a fix, nyet. So I treat this like I do with laptops, disable unwanted services.
After disabling services like bluetooth and others, battery life runs longer. Works best during long brownouts especially after a typhoon.
Be safe. Enjoy.
