I was wondering how often most people charge their 4S? I charge mine every night . It starts out on 100 but during the day I play a bit of games and use safari a lot so by the night it reaches 10 percent. Is this normal? My usage (from 100 to 0 percent) everyday is about 5 hours and a half to 6 hours. And standby time is usually around 15 hours Is this normal?
