The update coming out is said to address the idle battery drain by some devs who have tested it. They say it does nothing for the excessive usage drain which is what I have. I can't break the 2.25hrs of usage(email, app store, net). Tried all the usual things, restore, hard reset, turn off this and that. My idle time is great-uses less than 1% per hour, it's just screen on time is horrible. Could this be a hardware issue? Any thoughts? Thanks.
