I've been having the exact same problem since I got mine back in Oct. If I make a phone call that's more than 30 mins long while it's plugged into the wall it stops charging completely. I've tried taking the battery cover off & sliding the keyboard out and it helps a little but in the end it still ends up dying, it just takes a little longer.

There's really nothing we can do at this point but wait to see if HTC can hopefully fix this in a new radio/rom update. Just get another battery or two like everyone else as that's the only feasible solution for now.
