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?

Wireless charging always generates more heat than wired charging but it's not always a significant amount.

Wired charging ports get dirty, wear out

Batteries last longer with slower charges.

Batteries last longer with less charges

Batteries last longer If they never leave a moderate temperature.

Batteries last longer if they never drop below 20% and never go above 80%

Batteries last longer when stored if they are stored at 50% charge.

Putting that all in check you can take a couple year old phone to a fix it place and have the battery replaced. And they can also replace your wired charging port if necessary.
