Apple’s Clean Energy Charging is the future of electronics


Clean Energy Charging is not a conspiracy to reduce the speed or efficiency of charging when you plug in your iPhone. It is a harbinger of how most future electronics will consume power.

What is Clean Energy Charging?

Announced with iOS 16 and introduced in the US last fall, Clean Energy Charging selectively charges your device when lower carbon-emission electricity is available. In some regions, this might be during the daytime when solar and renewable energy production peak, but in most cases, it will be at night.

To support the feature, your iPhone gets a forecast of carbon emissions on your local energy grid. It then charges the device when the cleanest energy is available.

The effect is to reduce demand at peak times, and to increase use of renewable energy at those times when it is available, or demand is low. It matters because 22% of Apple’s gross carbon footprint is generated from device charging.

What happens with Clean Energy Charging?

When your iPhone is connected to power, it will recharge. If enabled, Clean Energy Charging may suspend charging until the cleanest energy is available. When it does, it will share a Lock Screen Notification that lets you know what’s happening and when to expect your device to be fully charged.

If you want to fill it with energy more swiftly, just touch and hold that notification and tap Charge Now when it appears. You can also switch the feature off, but at least some of the time an iPhone user may choose to take Clean Energy Charging’s advice, which means using lower carbon-emission energy.
