Why Charging Your Gadgets Over 80% Is Such a Bad Idea | iFixit News

This is a most excellent place for technology news and articles.
Am assuming it will drip to other manufacturers pretty fast. I think Motorola already has it.
I thought it was available in every brand already.
It exists in OnePlus, Oppo and Assus.
I wouldn't be surprised. Hardware should already be there since Android supports stopping charge when battery is too hot. Adding software feature to stop charge at certain percentage is not that difficult.
