iPhone 4S turn off itself while on standby.
Just got my iPhone 4s for 4 days, it turns off itself while on standby after use, have to do hard start by pressing shut off and home buttons, and battery is still 84%. This auto shut off happened 3 times already, did resetting as factory new twice, it is not solving the problem. Can anyone help me, before I head to apple store.
iPhone 4, iOS 5, 16GB Verizon
