Ugh horrible battery life iPhone 4

[GreggM3]

Got my phone swapped out the other day and today we started a road trip. My phone sat in the console unused and fully charged. After 10 hours it was dead. No BT or wifi.

You must have a lemon! My battery runs circles around my former iPhones. You should return it then.

Yeah something must be wrong, my battery is MUCH better than my 3gs!

I'm getting 36+ hours per charge, with moderately heavy use.

The same usage on my 3G would probably give me 6 hours.

Can also confirm my battery is amazing when compared to my 3G and 2G iPhones. Best battery on a phone I have had!

Usage: 5 hours 34 min (gaming, wifi, brightness 50%)
Standby: 10 hours 13 min

Still have 51% battery left.

Based on that I would get 11 hours of actual usage. Which is insane!

And that's my par over the last week. Around 9-11 "usage" hours. I hardly put my phone down since I bought it. It's almost replaced my laptop ha ha

Direct sunlight kills batteries. Is it possible that that's what is depleting your iPhone's battery?

As stated in the MANY threads on this issue: if you battery life is bad, then your phone is bad. Fight for a replacement!
