Use Clean Energy Charging on your iPhone

With iOS 16.1 and later, your iPhone can try to reduce your carbon footprint by selectively charging when lower carbon-emission electricity is available.

Learn about Clean Energy Charging

When Clean Energy Charging is enabled and you connect your iPhone to a charger, your iPhone gets a forecast of the carbon emissions in your local energy grid and uses it to charge your iPhone during times of cleaner energy production.*

Clean Energy Charging is only available in the United States and is on by default when you set up your iPhone. To turn the feature off, go to Settings > Battery > Battery Health & Charging and turn off Clean Energy Charging.

Some settings need to be turned on

Clean Energy Charging works together with Optimised Battery Charging to learn your charging habits. Clean Energy Charging only engages where you spend the most time and regularly charge your iPhone for long periods of time, such as your home and place of work. The feature doesn't engage if your charging habits are variable or you're in a new location, such as when you travel. Because of this and to get the carbon-emission forecast for your area, some location settings must be turned on for Clean Energy Charging to activate. Your iPhone doesn't send any of the location information that it uses for this feature to Apple.

Check the settings needed for Clean Energy Charging:

1. With iPhone 15 models and later, go to Settings > Battery > Charging and make sure that Clean Energy Charging is on. With all other models, go to Settings > Battery > Battery Health & Charging and make sure that Clean Energy Charging is on.

2. Go to Settings > Privacy & Security > Location Services and make sure that Location Services is on.

3. Go to Settings > Privacy & Security > Location Services > System Services and make sure that System Customisation is on.

4. Go to Settings > Privacy & Security > Location Services > System Services > Significant Locations and make sure that Significant Locations is on.

If you need to override Clean Energy Charging

When Clean Energy Charging suspends charging, a notification on the Lock Screen says when your iPhone will be fully charged. If you need your iPhone to be fully charged sooner, touch and hold the notification and then tap Charge Now.
