Healthiest way to charge Lithium Ion (lemmy.world)

When charging a phone wirelessly, there is sometimes significant heat generated. That combined with higher charging rates that are now coming out with the Qi 2 standard make me wonder what the ideal charge for the battery would be.

Most of the time I just toss my phone onto a wireless charger before bed, and don’t really care how quickly it charges. Would it be better to use a 5W brick with a charging pad? Should wireless be avoided and usb used instead?

Don't charge above 80%, don't discharge below 20%

This how I keep my phones healthy for 4-5 years at a time. I only this year upgraded my Pixel 4a 5G to a 7a, and only because Graphene EOLd the 4a.
