Clean Energy Charging is a feature on iPhone that tries to reduce a user’s carbon footprint by selectively charging when lower carbon-emission electricity is available from the grid.
When Clean Energy Charging is enabled and a user connects their iPhone to a charger, the device gets a forecast of the carbon emissions in their local energy grid and uses it to charge the user’s iPhone during times of cleaner energy production.
Clean Energy Charging is available only in the United States and is on by default when users set up their iPhone or after installing new iOS software updates.
How to turn on or off Clean Energy Charging on iPhone
- Open the Settings app and tap Battery
- Select the Battery Health & Charging option
- Tap the Clean Energy Charging toggle to turn the feature on or off
Clean Energy Charging works together with Optimized Battery Charging to learn a user’s charging habits. Clean Energy Charging engages only where a user spends the most time and regularly charges their iPhone for long periods of time, such as their home and place of work. The feature doesn’t engage if the users charging habits are variable or they are in a new location, such as when they travel. Because of this and to get the carbon-emission forecast for their area, some location settings must be turned on for Clean Energy Charging to activate.
