Im experiencing serious battery drain after .975 update through desktop manager for my 9630 tour

from a full charge battery runs out in under 4 hours– mind you, this is without web browsing, no additional applications or gps running, in my routine areas where signal strength is strong.

another symptom is that its running hot, very hot.

I’ve done multiple quick pulls, checked all my settings, power on power off etc, recharged, and my usual battery life is not coming back.

any ideas?? I really regret upgrading to the new software. thanks in advance
