iOS 16.1 includes a Clean Energy Charging option, which is intended to help iPhone users reduce their carbon footprint. For those who prefer a greener charging method, Clean Energy Charging charges only when lower carbon emission electricity is available.
Apple today released a support document on Clean Energy Charging, detailing how it works, how to disable it when necessary, and which settings must be active for it to function.
Clean Energy Charging is only available in the United States, and it requires Location Services, System Customization, and Significant Locations to be enabled in the System Services section of the Settings app to work.
It is enabled by default, and those who want to disable it must go to Settings > Battery > Battery Health & Charging.
When enabled, Clean Energy Charging allows the iPhone to obtain a forecast of carbon emissions in the nearby energy grid and use that information to charge the iPhone during periods of cleaner energy production.
Clean Energy Charging, according to Apple, collaborates with Optimized Battery Charging to learn a user’s habits, engaging only when the iPhone is charged for extended periods of time, such as at home or work. It does not engage if the user’s charging habits are inconsistent or if the user is in a new location, such as when traveling.
When Clean Energy Charging disables charging, a notification on the Lock Screen, similar to Optimized Battery Charging, indicates when the iPhone will be fully charged. Touching and holding the notification brings up a “Charge Now” option, which allows you to set the iPhone to charge to full capacity.
