Magnetic wireless charging is not effective
Using MagSafe to charge older iphones does not have magnetic alignment and is not compatible with older models of iPhone 11 and below.
Take the iPhone 11 Pro as an example, with MagSafe wireless charging, it can only charge 13% in 30 minutes, while the iPhone 12 can charge 50%. It seems that the MagSafe wireless charger is only suitable for the iPhone 12 series.
