Hi @Oldchestnut
A phone's battery output will lessen overtime however these are some tips I'm aware of and use myself.
- Https://www.samsung.com/uk/support/mobile-devices/how-do-i-clear-the-cache-on-my-device/ You may need to hook up to a Computer or insert your earphones to enter into recovery mode.
- Check in your phone's Device Care Section under Battery to see what's using your battery 🔋.
- Use Dark Mode and a Dark wallpaper.
- Check your sync schedules for email and other functions that sync.
- Use Sleep and Deep Sleep mode for Apps you don't need to run in the background or need notifications for.
- Personally I uninstall the Facebook App as it's a resource hog and access Facebook via my url Browser instead.
- Google Chrome is a resource hog so I use Samsung Internet instead.
- I turn off Adaptive brightness so set my brightness to just under 50%.
- Screentime Out is at 2 minutes.
- In Location I turn Off Nearby Scanning.
- Certain themes and 3rd party launchers will use more battery 🔋
- Widgets can use more battery 🔋
- 3rd party Launchers will use more battery 🔋
- In Settings > Connections > I choose Lte/3G/2G because the 5G option uses alot more battery 🔋 and as I don't use a 5G tariff it's pointless my phone searching for a 5G connection.
- Low signal connection can use lots of battery as the phone works harder to maintain connection.
- Battery Apps will use more battery 🔋 as they are by their very nature set up to continuously monitor the phone.
Personally I carry around a portable powerbank just incase.
Above all enjoy your phone. 😎
