Re: Fast charging

I think it varies by device and charger. Fast charging will heat up the battery, and excessive heat will shorten its life. That said -- my understanding is that the specific fast charging method, battery controller, ambient temperature while charging, and thermal design of the device itself can all influence the amount of actual harm to the battery.
