Hi Guys..my blackberry randomly hangs up in middle of a call (specially when the call is a little long) and a blank white screen is displayed. The BB doesn't restart until it's put on charge and then it reboots which takes about 15 mins to get the phone started. Has been happening 3-4 times a day.

This happens usually when the battery is about 50% full. Have been recharging continuously but the battery is being consumed very quickly.

Can someone please help me with the problem? Thanks!

I'd suggest getting a battery replacement and see if it works, preferably one with a longer life, so as to not experience the same incident.
