Look I'm sorry ok I'm just very anal about my cell phone and I always think I got a bad one because when I was younger I got bad model after model. Just never thought 5 minutes on the browser it would go down 1%. There's no way there's 40 hours of music playback and 10 hours browsing
Well that would get you 8.3 hours of internet browsing and apple probably makes it best it could possibly be withs brand new battery and no notifications and brightness all the way down and what ever they can do so that's not bad
