Make sure that all those apps are turned off. That will drain the batttery faster than anything. Check the top right hand corner of your phone, if there is an arrow pointing to the right or diagonally right, then something is still running in the background. There are also about 6 to 7 things that drain your battery quick to. Look them up in safari to find out what they are.
The more you use your phone, the faster the battery goes down. If you leave your phone on constantly, without ever turning it off, this also depletes the battery. Charge your phone every night and you will do better, with the life of your battery.
There is a thing in phone batters called alitheam so that means when you go to charge your iPhone only leave it on there for 4hours or you will do what's called over charging and it makes you iPhone battery die a lit faster than it is supposed to.
Judibug.. You are making me work hard. It is good to occasionally let the battery run down and then do a 100% recharge. Do this once a month. If you don't, the battery will establish it's own memory and then you cannot charge it to 100%.
