iPhone is different. It's well knows that iOS devices have better battery life. Lets compare Android with Android - which as we all know doesn't manage power very well ( at least not as good as iOS or Windows Phone ). I'm pretty sure you'll be able to get 4h+ screen time - it depends on what Spectre has been doing with his phone.Since my iPhone 5 manages 6/7 hours. (And no I'm not a apple fanboy) 3h is rubbish! My S3 managed just over 4h and i know the Z has a bigger screen and resolution but no excuse for putting small batterys in phones that have big screens and high res.
