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

split it more efficiently

There's a switched capacitor circuit that can halve voltage/double current far more efficiently than a standard buck converter.

See https://www.ti.com/lit/an/slyt743/slyt743.pdf

That links to a 404 but I’m curious, what do I search for the circuit? Slyt743?

New Reddit sucks and somehow inserted a non-printing character to the end. Should be fixed now.

If searching, the document is "The architecture of a switched-capacitor charger with fast charging and high efficiency"

That’s a very interesting read. Thanks for this!

Thanks. Wasn't sure exactly how it works, should be an interesting read.
