iPhone Battery Life

If you have an iPhone, please leave a comment regarding how your battery life is doing for you. Personally I have an iPhone 6 and it is terrible. About 5 hrs. On-screen time

I’ve got an iPhone 7 and it lasts me the whole day! Probably 7hrs screen time (but intensive)
Useually: listening to music, facebook etc, and YouTube

I upgraded from a 6 and noticed a big difference

I have a 6S Plus, With on screen time it lasts maybe about 6 hours but it depends on my level of brightness as well. I also ensure no unnecessary apps are running in the background.
