Now I Manually Turn The Screen Off(to save batt and not wait the 30sec as i set it to) and After I Do That,The Screen Will Come On Again Every Few Seconds With The Little Lock Symbol.By MY Cell Doin This,Its Drainin My Batt. I Turned Off The WiFi,BlueTooth,GPS,And Email,But Nothing Seems To Keep My Batt Life High.I Fully Charged It At Night And Once I Took It Off The Charger,In Less Than 30mins,The Life Was A 40%.WITH OUT ME BEING ON E THE PHONE!.Also When I Charge It.The LIght Stays On And Seems To Drain The Batt Till It Fully Charges.Also Takes More Than An Hour To Charge Even 20%.Can Someone Help?
