Do you have any 3rd part Widgets installed or is there something running in the back ground draining your battery? If not, I'd probably Exchange it for a new one. The one that I am using, for a couple of months now, will go for a couple of days on a charge. I would take it home on Friday and use it all weekend before charging it again on Monday morning.

It depends on how you use your phone sometimes.. Vdavi what is your usage like? What kind of things do you use your phone for? Where are you using the phone? Let me know and we will get to the bottom of this for you. Thanks!

Lets go back to the basic part battery drainage is cause by using the phone with its features, texting calling games or even playing songs, but it can also be drained if you have a moving screen saver
