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?

Healthiest = slow charging via cable to 80% limit.

The further you stray from that the worst it is for your battery.

There might be even greater benefit limiting it to below 80, but not as significant as cutting the top end. The majority of battery damage happens at the last 10% of capacity and high heat.

Do you think trickle charging via wireless would be significantly worse?

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.
