How to keep from spending too much time on your iphone
Instead of charging your phone overnight or carrying a charger with you, only charge it when you get up in the morning and when you get home.
Never charge overnight or over the course of a day. This will leave your battery with around 1/4 to 1/2 of battery depending how long you have until you go to work or such.
Have your phone on standby in the back seat. This way, you aren't tempted to use it.
