I'm running a Sprint 8830 and same OS as you and I do not have this issue. I do battery pulls every couple days (just because...)
Is it possible that your BB Messenger got corrupted during the install? I would try to reinstall the OS. Maybe even do a backup of the 8830, then wipe it completely and start fresh. Then do a restore.
Or it could just be because you are on VZW and not Sprint!
Let me know if I can be of further assistance.
