Hey there. New guy here. wondering if anyone can help me. so i had my phone and it would charge. but out of no where it when i would charge it, it would drain the battery instead of charging it. i got a replacement in the mail. i kept the battery and back plate and got the new phone. so now i'm using this new phone and i dont really know if this is good but this phone has been on, keep in mind i have been using wifi and a bunch of apps. and the battery hasnt died yet. i try and charge it and it says fully charged. this is my third mytouch within a week. anyone know whats going on? any help would be greatly appreciated.
