Healthiest way to charge Lithium Ion (self.technology)

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?

I was actually thinking of using the battery charge limit feature to prevent charging above 90%. Not sure I could do 80 without an charge during the day, lol

Pragmatically speaking, for battery health you should charge only as much as you need the battery, so it sounds to me that in your case that's 90%. Also, here's a paper about battery charging:
