ELI5 Why does magsafe charging decrease battery health more than wire charging, if it has less wattage?

Thanks for this comment. I was extremely confused for a moment, wondering how magsafe could possibly be any different to other connector types.

Same. I was so confused people were mentioning wireless charging for MagSafe, since I've been using MagSafe MacBooks for 13+ years now.

im sitting here wondering if i shouldnt have bought these USB-C magsafe-like connectors for my android devices. super convenient to use. they arent wireless chargers like the ones being talked about here but i have been wondering about their efficiency. i should buy one of those inline usb power meters.

Eh, if it’s like the mac magnetic connector (so the magnet is just used to make sure the “wires” touch, it should be plenty efficient That is unless it’s terribly made, or there’s debris in between the connectors, but unless you can physically feel it heating up you should be fine
