Battery loses full charge in about 90 minutes - new issue
I've got a 3GS running 4.2.1 and it's about 1 year old. I've always had a Mophie Juice Pack on it, and would usually go through both the internal battery and the external in about 16 hours of pretty heavy use, as I would expect...
Then 2 days ago the phone has decided to burn through the internal battery in about 90 minutes, and takes the external battery about the same time to deplete as well. The phone is always warm, and takes about 4 - 5 hours to charge back up.
I've tried restarting, restoring, and removing all apps but the base ones - but nothing has helped.
Is it possible for a battery to die from one day to the next (literally)? Should I replace the battery, or something more?
Is this a good question?
