If Optimised Battery Charging won’t activate
Optimised charging is designed to only engage in locations where you spend the most time, such as your home and place of work. The feature won’t engage when your usage habits are more variable, such as when you travel. Because of this, some location settings must be enabled for Optimised Battery Charging to activate.* None of the location information used for this feature is sent to Apple.
Make sure these settings are enabled:
- Settings > Privacy & Security > Location Services > Location Services.
- Settings > Privacy & Security > Location Services > System Services > System Customisation.
- Settings > Privacy & Security > Location Services > System Services > Significant Locations > Significant Locations.
* Optimised Battery Charging needs at least 14 days to learn your charging habits, so it won’t engage before then. Also, your iPhone needs to experience at least nine charges of five hours or more in a given location for Optimised Battery Charging to engage.
