Took me 20 minutes to go from 20% to completely dead last night. Earlier today I had it fully charged at my office. Left for 2 hours and had very light use, except for a 12 minute youTube video and 15 minutes of navigation, and it was down about 30%
I am using video wallpaper, but I am on my iphone4 also.
I don't give a rat's ass hour many hours others are getting. I care about how many hours I am getting. That is how it is horrible for me.
No need to get all mad. Maybe your unit is messed up doesn't sound normal. Do you have power save checked in the settings?
