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 very healthiest way? But maybe you won’t like it :)
Don’t charge above 80%, don’t discharge below 20%, charging current at 1/10 of the capacity, and always keep the thing at average room temperature.
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:
