A few weeks ago, I got an iPhone 6+.  I am not a hard core user of the phone, but I do use it.  Starting with my iPhone 5, I would turn off a lot of background tasks to improve battery life.  Well, the big battery in the 6+ really takes it to another level.  I had noticed that some nights I don’t need to charge it (even while running my sleep tracker overnight).  So I decided to not run it to see how long it would go.  Below is my first attempt.  I had a few hours of calls on the phone, including some speakerphone use.  Didn’t play much music, but did some browsing, messaging, took photos, etc.  All day Tuesday, Wednesday, and Thursday on one charge.  I could get used to this kind of battery life!
