Charge it whenever you need to, but heat is the battery’s biggest enemy. A slow charger is ideal since it generates less heat.

If your phone is plugged most of the time, you can consider setting a charge limit if you don’t typically use more than what limit is supported.

Not a really good answer: I just stopped caring about it.

P6P here had it since day one. My battery is not in the best shape, but not terrible either.

I just charge when it’s needed and adaptive charging has done a pretty good job of keeping the battery healthy.

Overall though at the end of the day I’m not sure there’s too much we as the user have control over.
