Kill my battery.:-(

Why?
It's big trouble...:confused:

When you charge the phone, does the back of it, just above the battery become warm / hot? If it does, it is the power amp that is faulty. Really Really common in t28's.

You need a hot air solder station to change this i.c

Not warm/hot the batt.
