Please only post battery life for the iPhone 4S here, good or bad. Just usage, standby time and battery % left. I want to get an idea of people's averages out there. No complaining about poor battery life, there are other posts on here for that. Here's my usage history. I switched my 4S on yesterday morning (29 October) at 7:45am (at 100 percent). I played a game for 25-30 minutes. Connected my 4S to my TV via my Apple Digital AV Adapter and watched a video podcast for around 10-15 minutes. Listen to a couple of audio podcasts for around 10 minutes, sent a couple of text messages, had a 3 minute telephone call, wirelessly synced with iTunes for around 10 minutes on and off. I switched my 4S off at around 11pm last night. I switched my 4S on at 8am today (30 October). I have had the screen on for around 5 minutes on and off whilst I was going through some settings, I have taken a couple of pictures which were then sent to iCloud via my wifi. So far my stats are: Usage= 2 hours 55 minutes Standby 15 hours 16 minutes And my battery is on 54 percent. Does this seem to be what is/can be expected/normal for the battery on the 4S or would you say I have a defective battery. I'll admit, with iOS 4, I would probably have had more battery life left, but iOS 5 probably has more processes running so comparing it to iOS 4 isn't a fair comparison perhaps. Too be honest. I don't think I have a battery issue compared to what some people are seeing, has some posts that I've read elsewhere are having shocking battery drain issues. I look forward to seeing your usage, standby times from your iPhone 4S's.
