I bought a new phone with Type-C port and supports 25W fast charge. As you know, they no longer send adapters with new phones.

My laptop also has a Type-C port (so I am using type-c to type-c cable) and turns out my laptop can charge my phone at 25W.

I use my laptop plugged-in(battery conversion mode at %80) and my question is will it damage the battery of my laptop or phone in the long run?
