I just got it yesterday, I was so happy. Not surprising, I found the battery draining pretty fast. When I open the phone it is already at 57%, I didn't charge it to full as I decided to drain it first. Battery is not much a problem if I keep it on standby, what is really concerning is when I use the phone on wifi or just reading iBooks with wifi and 3G off. As long as I am using the phone, the battery is like draining 1% every 7-8 mins. Is this normal? I used it on and off for about 2 hours and it dropped like 35%. ( I have my wifi and 3G turned off), my screen is set at almost the highest brightness. I just feel that the battery is draining way much faster than my iPad 2. I can play with my iPad 2 for the entire day at all time before the battery get drained. This does not seem possible with the new iPhone 4s.
