I use it roughly 5-6 hours a day maybe. Used to use it quite a bit more before I worked from home to listen to music, listen to movies, etc., while at work in the office. Since I'm home now, I watch TV while working but still use it during the day to check email, Twitter, personal email, texting, personal calls, etc. It's ridiculous. I never thought I'd become so dependent and utterly in love with a freaking phone. Not that I'm complaining.
