Just go to Settings>About phone>Battery use and you’ll get an easy-to-read chart showing what’s been going on since your phone was last plugged in.
Chances are the display (as in the phone’s screen) will be near the top of the list, so turning down the brightness might be one of the first things you try.
After that you will see the next big hitters.
A service or application may be misbehaving and be the cause of your excessive battery drain.
If it’s an application that’s causing it, try uninstalling and reinstalling the app and monitor it for 24 hours.
If it happens to be one of the Android services some further research will be required to identify what is the cause.
