OK....I want to post my .02 here.
My battery life had been pretty good. But started getting Very bad.
Had to turn off the 3g to make it last - basically making it a dumb phone.
Switching the 3d back on to check something...would cause immediate and sudden battery drain.
Had to do a battery pull and noticed the Battery was bulging and didn't fit flush. Took into the sprint repair center across the street. Where they were anything but helpful. Basically shell out $45 for a new battery or it will explode in your pocket...
Ordered one on amazon for $17 dollars....1900 AWESOME - Battery life is back to where it should have been.
I think it sucks that sprint and other carriers will lock you into a 2 year contract then not support that device for the full two years....
***end Rant** *
Anyone needing a replacement that will fit into you current housing and Case...I HIGHLY recommend
