I fully charged my Z10, and then lost 50% power within only 1 and half hour.
During the time, I had no call, only two messages coming, I replied one of them.
I did not play game, watch movie, most of time the screen was off.
Happened this morning after I upgrade, very weird, never happen before upgrading.
Will test in next few days.
