Battery is holding up a bit better than my 4S
Had it fully charged at 7:30pm -- used it, made calls, made many texts, browsed many a website, used the GPS for driving around, had bluetooth on as well. Took photos, played in burst mode, watched youtube videos, watched instagram videos, listened to a podcast and 5 hours later I'm at 36%
I feel like I would be at 20% or under with my 4S with that type of usage.
