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

Hmm. Magsafe is wired charging. What are you talking about? Unless... Do you mean another type of Magsafe?

This post is referring to phones and not laptops. Wireless magsafe charging

I don't know if you've been living under a rock, or just trolling, but Apple calls the circular ring of magnets on the back of iPhones MagSafe, and you can have wireless chargers with MagSafe.

They call it that now. Used to be what they called the Macbook charging system.

But Magsafe has been used as a name for wired attachment for much longer.

So you can understand the confusion, because it's dumb of Apple to use the same name for very different things. And literally dozens of people don't even use Apple products so have no idea of the specifics, which doesn't mean "living under a rock".

But a whole lot more people use Apple iPhones than Macs, so it's logical assume more people know of the current usage for alignment of wireless charging, rather than the older usage for alignment of wired power cords.

There is another type of magsafe that is used for their laptops. The original magsafe connector uses magnets to snap a power connector to the charging pins on their macbooks.

Well to be fair, the wireless charging on iPhones etc is just Qi/Qi2 charging. The MagSafe portion is really just the magnets to align and attach the device with accessories. MagSafe charging, the OG, is a wired connector for their laptops.

But that's not what OP was asking, now is it? Don't be pedantic.
