Check your battery usage.
To check the battery usage: 1. From the home screen, swipe either up or down to access apps. 2. Select Settings. 3. Select Battery and device care. 4. Select Battery. 5. Select Usage since last full charge.
From here you can see what applications and processes are using the most power.
Check XDA developers. They'll probably have a huge thread on how to save battery.
My quick advice is keep your phone on WiFi as much as possible, especially if you're in a low carrier coverage area; limit your phone's resolution to FHD+ intsead of WQHD+; use Bixby routines to change settings depending on location; and use 4G/LTE instead of 5G if you don't consume a lot of media.
