I bought the Nexus 4 and couldn't believe how little runtime I was getting. Even paid $5 for juice defender to turn off wifi / automatic downloading. It's the screen. Went back to my iPhone 4. Sites should really do a better job of reporting battery life, although I guess I should have guessed from the Anandtech table [1]. Gave it to my brother to jailbreak and underclock, to see if it could be saved.
