How to improve battery life on the Samsung Galaxy S6, S7 and edge:
1. Tweak automatic brightness slider
Samsung devices allow users to set brightness even when under automatic mode.This feature is very good, as your phone still have adapting to your surroundings to auto change brightness.And as you should know, the display is consume battery more so it should be set to automatic mode but best if you set to 15-20% brightness without auto mode.
A simple, but efficient fix. A good start!
2. Work the radios!
Mobile data also consume more battery.But if you need it all the time, so it makes no sense to turn it off unless it is an emergency.If you still want to optimize battery while mobile data is turned on then, all you have to do is optimizing your usage of networks.
It’s pretty simple. By default, your phone will be setup to a 3G or LTE network.if your usage is only e-mail sync and some Facebook Messenger/Viber here and there then switch to 2G GSM network which will work great if you want to optimize battery.All you need is a tiny widget on your homescreen to quickly switch “2G/3G/LTE network.
3. Smart stay
Smart stay is battery consuming feature that allows your Galaxy S7 and S7 edge to detect your eyes when you are looking at your display. If you are looking then screen will never timeout and go to sleep as long as your eyes are on display.
Turn off smart stay if you are not using because its battery consuming.
4. Screen timeout
Don’t set too long timeout for the display. This won’t save you battery all the time.
Best option to save battery is to move down to like 30 seconds or less.

As for notifications,Always On Display actually useful.
6. Turn off the LED indicator
