Normal battery usage of iphone 4?
Okay so after i updated my iphone 4 to 7.0.2. My iphone battery usage is 4 hrs 30 mins. Is that normal? Some says that their iphone 4 last for 6 to 8 hours of usage which is the normal battery life. I don't usually play hd games. I just on the Wi-Fi and surf the net. What should i do? Oh. I already restore it because before it was 2 mins 1% with Wi-Fi on.
