What Finally Killed AirPower

I do this too, so don’t take this as criticism.

Isn’t this bad for the battery? ISTR you want to keep the battery between 20 and 80 percent. More than that and it winds up heating up the battery during charge. Or is that just for electric cars?

That was the case, I think, with old NiCd batteries, but with lithium ion batteries, you maximize battery longevity by keeping it mostly charged, I read recently.

Not really, that’s still the sweetspot for most lithium batteries as well (being under 20% is much more critical than being over 80% though).

What’s different between them is battery memory effect. With NiCd & NiMH you are supposed to let it discharge until 20%, then continuously charge up, and then repeat.

With Lithium based batteries it’s a recommended practice to charge in short bursts and keep the battery at a medium level.

In any case, most devices now a days will manage the battery in ways that you should not really bother. It’s amazing the conplexity that battery systems have nowadays.
