Which is healthier for the battery: MagSafe wireless charging or …
Wired charging generates less heat at the same charging level (IE, 15W vs 15W). This is why most phones, iPhone included, charge faster when wired. With Magsafe, you can expect the iPhone to get roughly as as hot at 15W charging (12W for mini models) as they get at full speed on wired (18-27W, depending on state of charge and specific model).
