I know there are tons of battery threads but most if not all of them are for poor battery performance, so I wanted to start a thread for positive battery performance. I was worried when I got my 4S 2 days ago because of all the negative battery stories I have heard. To my surprise, my battery is actually really good!! I did one full cycle charge from 0% -100% when I got it and it's been great ever since! I am currently at Usage: 8 hours, 8 minutes Standby: 1 Day, 5 Hours Battery Percentage: 3% I did plug it in for about 5 minutes to sync with iTunes but no other charging was done. I only lost 4% battery last night while slept and I have actually been trying to drain the battery so I can get one more full cycle charge in.
