    Just got my iPhone yesterday and loving it. I was wondering how is the battery life though? I know most smart phones when you leave it on the charger it doesn't hurt cause it stops charging when full now that the same with the iPhone? Also I feel like my auto brightness isn't working. When I have it on it seems to always be the lowest brightness and never change many suggestions?

    Battery life is great, it lasts at least 3 times longer than my previous iPhone (1st gen 2007). Don't bother using the auto-bright, it's just better to set it yourself. It almost never works the way you want it, hopefully that's fixed in iOS 5. :D

    The iPhone 4 battery life is astounding. I am on Wifi most of the day, either at home or in the office, and regularly get 3 days of use out of my phone. Of course, I do not receive many phone calls, mostly texts, emails and data use.

    Make sure you turn off any non-essential services like bluetooth and push.

    Don't know about leaving it plugged in all the time ... I think that negatively affects the battery life of all phones, laptops, etc.

    Have you tried turning up the brightness in Settings?

    Yeah I'm not using auto bright. Just a low brightness setting now. Maybe it's push. But last night around two I went to bed with like 66% I believe and I just woke up with 54% that doesn't seen normal am I wrong?

    Perfectly normal if not on charge and set to sync anything e.g. Email... Also how good your cell signal is will have a bearing as a weak signal will require more power. Try putting it in airplane mode overnight; you'll see it hardly drops at all.

    That's my experience as well - the Data is really what drains the battery.
