Li-ion batteries have a unique charging pattern that greatly affects their longevity. Similar to how running for shorter distances at a faster pace covers less ground than running at a marathon pace, charging Li-ion batteries to a lower percentage can actually extend their lifespan. By charging the battery to 80% instead of 100%, the battery can transfer four times the amount of energy over its life. This means that the battery can be used for a longer period before reaching the end of its rated life. It is generally agreed that charging to 80% is a good compromise between convenience and battery lifespan. So, when it comes to batteries, it’s all about running smart rather than running fast.
