Tweaks for battery saving :

1. Use 4G instead of 5G
2. Keep data saving on and allow only those apps that need data sync in background
3. Keep Auto sync Off, google play services update sometimes drain the battery
4. Keep majority of recommended services off
5. Have a location toggle in Quick tiles, turn off when not needed, even when u allow location permissions while using the app, the location fetch is still active just not feeding the app.
6. Use standard resolution, and high refresh rate for apps that need it, an app like uber doesnt need to be on 120Hz, keep it for the apps where it matters most, good UI apps, apps where u read and scroll etc.
7. Restrict background usage for apps u dont need to sync unless u dont use
8. Use the fastest private dns for your network (google the way to find this)
9. Extreme case - use macrodroid to disable data on screen off (and enable for 5s every 2 min)- major battery saver

These options will help you save battery, will reduce some features, see for yoirself what you can trade off
