This is not an iOS 8 battery drain thread but just a general question. Apple is quoting on the iPhone 6 figures like 11 hours wifi browsing. I'm getting like 6-7 hours so do all my friends. It was the same for the iPhone 4 & 5s I had which where also at least 3-4 hours short of the quoted battery life. What do these estimates actually mean? Am I missing something since I'm never anywhere near them. In contrast on my iPad I constantly get the quoted 10 hours, if not more.
