Start with a few everyday settings. The names of menus vary between TECNO models and HiOS versions, so use the search field in Settings if needed.
Start with the screen
Reduce brightness or enable adaptive brightness. Set a shorter screen timeout so the display switches off sooner when you put your phone down.
Check what is using power
Open Settings and search for Battery. Review the apps using the most power. Restrict background use for apps you rarely need, remembering that this can delay their notifications.
Use battery saver when needed
Enable Battery Saver when your charge is running low. Keep Android and your apps updated, and avoid leaving the phone somewhere hot, especially while charging.
Charging habits
You do not need to run the battery from full to empty to teach it its capacity. Use a compatible charger and follow your phone’s charging instructions.
