Do that and a phone or laptop battery will happily last several years. Every phone, tablet and laptop I own runs on a lithium-ion battery, and those batteries wear out from two things above all else: sitting at extreme charge levels and getting hot. Once I understood that, I stopped chasing myths and focused on a handful of habits that actually move the needle. Here is what I do and why it works. What charge level is best for battery health?
