>This is why I never use fast charging, avoid wired charging in general

Wireless charging isn't a silver bullet either. It generates tons of waste heat, which is also bad for batteries. I'm also not sure why you're so against wired charging, especially since you have to go out of your way and pay a premium for fast charge capable chargers. If you buy a bog standard 5W/10W charger, you're not fast charging. If you plug your phone into your computer, you're likely getting slow charging (0.5A to 1A).

I'm not against wired charging per se, I just think wireless is better.

I use an extremely old wireless charging stand that doesn't even hit 500mA. It gets warm, but not hot. It takes all damn night to charge which suits me just fine.

That said, I agree with you, which is why I've explicitly disabled fast wireless charging. The heat is almost as bad as excessive charge current. Though both heat and excessive current together is much worse than either individually. Which is exactly what you get with super fast charging modes, and why I disable those modes.

Generally, phones ship with at least a 20W charger these days. It's fine, probably.

Really my whole deal here is that my phone has a non-replacable battery. Paying someone to crack it open and replace the battery would cost a lot more than I'm willing to pay. My goal is to preserve the battery for as long as I can so I don't have to trash the whole phone.

Ultimately, this is a decision made for myself based on my own professional experience with lithium batteries and associated electronics. I definitely wouldn't recommend everyone do everything I'm doing; it is a bit excessive. But that's just how I like to do things.

Yeah I disable all the fast charging modes too. Except when I really need them for a quick top-up. I think it's great to have the capability when needed but not something to use every day.

If you're on the road and using your laptop's USB-C charger to charge your phone then it'll easily supply enough power for the fastest charge mode of any phone.

Yeah, it could supply 60W or even more. But it won't, because most people who care about this stuff set both the charging rate limit and max battery percentage limit in the phone's settings and don't worry about it anymore.
