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?

The main issue with wireless is heat, at any charging speed it produces more heat than wired charging equivalent. With that said, if your room/charging spot is well ventilated and the ambient temperature isn't too warm to begin with, it could be negligible.
