This is a simpler version of https://manifold.markets/dreev/will-my-battery-redqueening-strateg

I have a 16-inch Macbook Pro made in 2021. It has a Magsafe charger that charges extremely fast. You can also charge it with a phone charger with one of the USB-C ports, which takes forever. Is one or the other generally better for battery health?

(I'm actually biased towards the phone charger because (a) that way I can leave the Magsafe charger in my bag for when I travel and (b) the phone charger is so slow that it's easier to keep the battery mostly in the recommended 40-80% charge range. But this may be misguided!)

This resolves to YES if Apple has official guidance recommending using the Magsafe charger or someone who knows what they're talking about has an opinion.

PS: Turns out I really never need the Magsafe charger, even when traveling. I just charge it overnight with a phone charger, or use a phone charger while working and it keeps up well enough.
