Clean Energy Charging enabled by default in the US on iOS 16.1

After casually mentioning the arrival of a new feature called Clean Energy Charging, Apple details it on its site. Enabled by default on iOS 16.1 and only available in the United States, this feature aims to reduce the carbon footprint of iPhone users by preferentially charging phones when low-carbon electricity is available.

Concretely, the iPhone receives a forecast of carbon emissions on the local electricity network and bases itself on this to charge during periods when energy production is the cleanest.

Clean Energy Charging works in concert with Optimized Battery Charging, which uses daily charging habits to queue charging beyond 80% when possible. Apple says the new option only activates where users spend the most time, such as at home or at work. It does not kick in when charging habits change often or when travelling.

In order for the iPhone to receive the carbon emissions forecast, certain geolocation permissions are required, as power grids are not the same across the United States (geolocation data for this feature is not transmitted to Apple ). All of the following settings must be enabled for charging with “clean” electricity to work:

  • Settings > Battery > Battery status and charging > Optimized battery charging and Clean Energy Charging enabled
  • Settings > Privacy & Security > Location Services On
  • Settings > Privacy & Security > Location Services > System Services > System Personalization Enabled
  • Settings > Privacy & Security > Location Services > System Services > Important Places On

In the same way that a notification is displayed when the optimized battery charge is in progress, a notification warns of the activation of Clean Energy Charging and indicates when the iPhone will be fully charged. In the event that you need an iPhone 100% faster than expected, it is possible to override the function by touching this notification and then the option “Recharge now”.

For now, Apple has not said anything about a possible future availability of this feature in other countries.
