BATTERY DRAIN PROBLEM POSSIBLE SOLUTION
I have swapped my Inspire at the ATT support center 4 times in the last 3 weeks. It started as a bizarre behavior. When I plugged it in to charge, it actually discharged the battery. DIdn't matter if it was AC Adaptor or direct to computer. Got a new phone.
worked for one day, then did the same thing.Got a new phone.
By this time I suspected it was the micro-usb port on the phone, it's a terrible plug to use for this purpose. Well I think I was proven right, plugged the power cord in, phone shut down instantly.
Each time I took it to AT&T they were able to duplicate it with their cables.
Got new phone
Plug it in as rarely as possible (to computer only). Bought batteries and swap them usually once a day. AT&T was actually nice and helpful, I asked them for spare battery covers since It doesn't feel like the battery cove was designed to be opened a lot. They handed me 3 of them no charge. I just couldn't deal with re-loading everything on myphone again.
SO FOR ALL THE BATTERY AND WEIRD PROBLEMS YOU ARE HAVING, SEE IF THEY RELATE TO PLUGGING THE USB CABLE IN. I AM CONVINCED (AS WERE THE AT&T FOLKS) THAT A SHORT IS DEVELOPING IN THAT PLUG OVER TIME.
HOPE THIS HELPS.
