Ways to improve battery life

[Jerhen]

I currently have a 13 month old iPhone 6s and I am going to attach the battery usage screens that I get on a fully charged battery. I am just wondering if this amount of usage seems normal and am wondering if there are any settings I can shut off to improve battery life. I currently have wifi assist, background app refresh, and Bluetooth completely shut off and this is my usage.

It also seems like my screen on time is barely anything for each app in the battery menu. It seems like I am not getting a lot of usage out of my battery.

Seems normal with your almost 2 hours of YouTube usage.
