With Androids I generally get some idea of the battery performance from the screen-on time. The only way of doing that on an iPhone so far as I know is to add up the times of on-screen-usage for each app in Battery Usage. I got about 140min SOT from my 4s today, with the battery down to 21% from 100%, using Auto brightness, and most of the time on good mobile signal, with a short time on good wifi.
