Sleeping apps
Opening apps all day can drain your phone's battery quickly, but you can save some power with sleeping app
settings ( "https://www.samsung.com/us/support/answer/ANS00088422/" ) .
If there are certain apps you rarely use, you can set them to sleep in the background so your battery won’t drain
as fast. You can also set apps to sleep automatically when you haven’t opened them in a while.
Power saving mode
If you know you'll be away from a charger for an extended period and you want to make sure your device will last,
just turn on Power saving mode. This way, you won’t have to worry about a low battery.

switch to turn it on. This will limit certain things on your device, such as background network usage and syncing.
You can use additional power saving options as well:
