magsafe charger
could the iphone 12 magsafe charger work on my iphone 11 or do i need a special case?
iPhone 11, iOS 14
All iPhone models that support Wireless Charging (iPhone 8 onwards) are compatible with the new MagSafe Charger. You do not need a special case.
However, only the 2020 iPhone 12 models will attach magnetically to the MagSafe Charger.

"The MagSafe Charger makes wireless charging a snap. The perfectly aligned magnets attach to your iPhone 12 or iPhone 12 Pro and provide faster wireless charging up to 15W.
The MagSafe Charger maintains compatibility with Qi charging, so it can be used to wirelessly charge your iPhone 8 or later, as well as AirPods models with a wireless charging case, as you would with any Qi-certified charger.
The magnetic alignment experience only applies to iPhone 12 and iPhone 12 Pro models."
