So guys, for the last two weeks I notice something pretty strange. My batter usually last a day with WiFi an Cellular data on all the time and the normal abuse. The phone hits 1% and it dies so I plug it in and turns on at 4-5% battery. The last two weeks my phone shuts down at 10% battery or 7% battery, OK. So I plug it in and it immediately shows the Apple logo, the phone turn on with about 8% battery. This is really annoying!! I am using an iPhone with with iOS 7.0.4 What could be the issue? This wasn't happening when I first installed iOS 7 a couple of months back..
