OnePlus: Stop Battery Saver From Switching Off After Charging

OnePlus phones include a setting that automatically disables Battery Saver once the device reaches a high charge level, typically around 90%. This is meant to prevent power-saving restrictions from lingering after you unplug the charger.

The behavior comes from the Turn off when fully charged option inside the Battery Saver settings. When enabled, the system assumes you no longer need reduced performance or background limits because your battery is topped up.

Some people prefer Battery Saver to stay active regardless of charge level — for example when travel or long meetings make battery life a priority all day. Disabling the automatic switch keeps the mode running until you turn it off manually.

To adjust this, go to Open the Settings ➔ Tap on Battery ➔ Tap on Battery Saver ➔ Enable or disable Turn off when fully charged. Toggle the option off to stop the automatic deactivation, or turn it back on if you want the original behavior.

This setting only affects when Battery Saver switches off automatically. It doesn't change when the mode turns on, and it has no effect on other power management features like adaptive battery or background app limits.
