I had great battery life pre 5.0.1 but post update it was really bad so I was advised to to a restore via itunes which I did last night. This morning I unplugged the phone at around 9 and except for around a minute when I plugged it into itunes it has been unplugged. It being a Sunday, and me wanting to see how much I could use the phone I used it quite a lot, but not excessively. I went on you tube quite a bit, played games quite a lot, safari quite a lot, texting one person for over an hour - i really tried to push it. Ironically I didnt make any phone calls! So it is now almost midnight an my usage stats are: Usage 6 hours, 39 minutes, Standby, 15 hours and 31 minutes with 2% battery left. Is this good? And if so, good for 4s or as god as 4? And taking into account that I did do youtube, games, and safari - if I had used it to make calls would my usage and battery been worse? I hope I'm not offending people with these questions, I just want to figure out if my phone is "normal"!
