Improve Your Android Operating System’s Battery lifes
Set display brightness to adjust automatically. Turning down the brightness is obvious. But the automatic adjustment setting is less well known. Activating it means the OS will automatically dim its display in darker environments, including seemingly well-lit indoor rooms.
Kill extra tasks. This one is controversial, because Android does its own task management. Each new version of Android has improved automatic task management. But some programs still misbehave, especially social-networking apps that like to poll the Internet frequently. Having a task killer like Advanced Task killer around can help neutralize unexpected network access and lengthen you’re your battery life.

Dump unnecessary home screen widgets. Just because they’re sitting on the home screen, seemingly inactive, doesn’t mean they’re not consuming power.
