the problem on this phone and many phones, is too many apps running in the background, both ones that came on the device and ones you loaded - the solution is to root the phone and install a clean, stripped down ROM such as Slick ROM V5 from XDA Developers website. get it here: http://forum.xda-developers.com/showthread.php?t=2084431 I bought one of this exact phone, it would get hot and drain the battery quickly, after installing the barebones ROM above, it is much faster, runs cool, and the battery lasts 2 days!
