on the phone if you go to the dial pad and type *#*#4636#*#* and go to battery history look for processes at 100%. On my EVO I would click on "other usage" and change it to "Partial wake usage" I would see Media at 100% (blue line all the way across). I found that after I reformatted my Memory card to FAT 32 (copy all items first to computer) the Media stopped running at 100% allowing my phone to sleep. You can check to see if your phone is sleeping by menu/setting/about phone/battery/ look at up time and awake time. The two times should be different if you have had the display off.
