Why is my iPhone 5's battery draining so fast suddenly?
My iPhone 5's battery is draining very quickly. Yesterday was fine. I don't use my iPhone that much, so normally, the battery level is around 75% at the end of the day. However, today, it is down to 25% already and it is only 3:30pm. What is going on? Please help me!!
iPhone 5, iOS 6.0.1
