That's strange because normally I use twitter and the music app a lot and only get 5-6 hours of usage before it dies but yesterday, I used twitter, safari, played some games, downloaded and used sound cloud, used YouTube and played a lot of music and got 8 hours 25 minutes usage with 5% left...the reason why some people get 8 hours usage is simple. they use apps that don't kill the battery, such as messages, phone calls, music etc..
if you use instagram, twitter, THEN YOUR BATTERY WILL DIE faster
so simply put, if you don't use social media, your battery will be awesome.
i get this type of usage with twitter, instagram, facebook, safari and messages. no music whatsoever
5 hours, ~30 minutes
15 hours standby.
if i listen to music in the day, the usage goes up over 6 hours.
the people posting 8 hours usage, how bout you tell us WHAT you're doing on your phone. because i, too, can post amazing battery life if i leave my music player on all day.
I think the battery is trolling
