Hmm my ip4 batt drain quite fast thou after updating to iOS 5.1..from 100% drop to 50% very fast. Then after that batt drop slower edi thou with same usage.

But im very impressed at how durable the batt is during gaming. Played Infinity Blade at 100% for 1-2hrs, batt dropped to 60-70%

Same here. Battery life drops fast on ip4 but seems quite ok on 4s.

At normal area still ok, but when i go to those area that i get 1 bar before my upgrade, i will get no service now.

I feel no difference with OS 5.1 on battery life on iphone 4. Same long lasting also

Is it? Mybe it is due to my heavy gaming activity & FB

We are on the same boat. Sometime hard to determine as each of us have different style of using phone...

Alamak. I heard the battery drainage already fix? But don't seems it was solved from you guys comment.

guys, i do not want to update to ios5.1. But today i checked my software update, the download is paused and it has already downloaded half way. and says that i can resume my download next time i connect to wifi. How do i stop this? =(

I believe it varies between individuals. It also depends on ur phone activity. Chill & enjoy ur iphone

so far so good, battery life improved

not much of different...
