With iOS 16.1, released on October 24, 2022, Apple introduced a new feature called Clean Energy Charging. The fully optional feature only seeks to reduce the environmental impact of your iPhone by charging it when the electricity sources in your area are greener (since energy sources fluctuate throughout day and year).
A support document from Apple details how this works. It is currently only available in the US, but may expand to other regions in the future. If possible, your iPhone will get a forecast of future carbon emissions for your local energy grid and try to adjust its charging in times of cleaner energy production. It works with the Optimized Battery Charging feature to learn about your usage and charging habits, to ensure you’re never stranded without a charge when you need it.
Throughout a typical day, electricity demand fluctuates, which often makes it necessary to supplement electricity from on-demand sources such as natural gas power plants. Energy sources such as solar and wind generate different amounts of electricity depending on the time of day and weather. Hydroelectric power is constantly changing with the times.
But it’s all predictable when you have the data. As an example, even though you might plug in your iPhone at 8 p.m., your phone might know that, based on your past usage history and the fact that it has a 27% charge, it’s not you need to charge it more. and you better wait a few hours until the gas peaker plants ramp up and most of your electricity comes from hydroelectric sources.
If you don’t like this feature you can turn it off. TOMORROW SettingsCHOOSE BatteryTHEN Battery Health and Charging and turn off Clean Energy Charging.
