Useful to know

Will a bigger charger charge my phone faster?

Only up to the most your phone accepts. A 65 W charger on a phone that takes 25 W charges at 25 W.

Why does it slow down after 80%?

Lithium batteries charge more gently near full to limit heat and wear. Stopping at 80% saves time and helps the battery last.
