Is anyone else having battery problems? Because, despite every user testimony that the battery life is awesome, i'm not experiencing the same awesome battery life. Any light usage (and I mean light, like just messing around with the phone), is almost instantly decreasing the battery life by 1% point. After two hours just sitting there, the battery is now at 68%, before leaving the phone for two hours the battery was at or around 89%. So, anybody have thoughts on this?
