Apple launched the 2024 ‌MagSafe‌ charger alongside the iPhone 16 models, and it is able to charge them at up to 25W. For the iPhone 12 models to the iPhone 15 models, charging is capped at 15W.

Because firmware updates are released quietly over the air, Apple does not provide release notes. We don't know what new features or bug fixes might be included in the software.

There is no clear method for updating a ‌‌MagSafe‌‌ charger's firmware, but it needs to be plugged in and connected to an Apple device for a firmware update to initiate. You can check your ‌‌MagSafe‌‌ Charger's firmware by following the instructions in our MagSafe Charger how to.
