The extended battery seems to last a very long time although getting it fully charged properly has been impossible since the update. Last night I plugged the phone into an outlet and this morning (again) the phone still doesn't have that "full" green light signal. It should not take over 8 hours to charge 65% of the extended battery. This AM I awoke to find it at 75%. Couldn't get it above that so I did a reboot. Upon rebooting after unplugging the device, I got a 95% reading. ?????? Something is seriously wrong with the power monitoring now.
