Well, like many of us Dinc users...we struggle with battery life. I could barely get my battery to last more than 8-10 hours of light use....even using battery managing apps, etc.
If you haven't tried the MIUI Rom....download the latest and give it a try. I've always loved MIUI...but the latest version added some really cool features. EVEN BETTER...MUCH better battery management. For the last 10 days, my battery has been lasting at least 24 or more hours of light use. 12-13 hours of mod to heavy use. I couldn't believe the difference, but the update to MIUI 1.6.17 is the only thing I've changed.
