Never understood posting screenshots of battery stats. They really are meaningless unless you also provide an accompanying breakdown of what you were doing during your usage time, what type of internet connection you were using, the quality of your cellular connection, screen brightness, etc.
I could just turn on spotify, turn the screen off, and stream over wifi....and subsequently post a screenshot that shows I got 12 hours of usage. I could then jack up the brightness and stream youtube videos over a weak 3G network and post a screenshot of 3 hours. If I didn't tell you what I was doing during each one, you'd think my phone was faulty.
