    Default iPhone4 Battery Drain To Zero Overnight
    My iPhone4 is dead after leaving it overnight from a fully charge state. It started to happen a few days ago and I thought it just needed a reboot.

    I do not have many apps. About 12 from the appstore I have been using before this battery issue. What is weird about this battery drainage is that, after letting it charge for a few minutes to get it kick started to the homescreen, the battery percentage would start from 80% charge and it gets fully charge in about 30 minutes. The phone is not in JB state. Although it has in the past.

    Is this a battery issue or software? Would a restore of firmware help fix it? Recently, I have been restoring from backup multiple times. It's restore from backup and not a full restore of firmware. Would that had cause a glitch?

    You can try to restore and setup as new, don't restore from backup and than see what happens. But, I am pretty sure, it's a battery issue. Time to change it....
