The current will power your laptop and it will also charge your battery at the same time. Let's say your battery is at 35% and you plug your laptop. Plugging the laptop isn't just for charging the battery, it also powers the laptop instead of the battery.

I don't exactly know how they calculate that. If you had kept your laptop plugged in and used the Maximum Lifespan option from the start, you'd probably be at 1 charge cycle or something like that, I assume. Afterwards the battery capacity will drop to 80% of its initial capacity. Under normal usage conditions and in ambient temperatures (25℃), the Li-ion battery is expected to discharge and recharge normally for 300 cycles (or about one year). The life of a Li-ion battery is approximately between 300-500 cycles. The smaller the better if you want longer battery life. The laptop rarely drops below 60% to begin with, but even if it does, it's considered a small depth of discharge, which is what you want. In fact, it will allow your battery to last longer. There's nothing wrong with using the 60% option while always plugged in. If I use this 60% limit and have the laptop plugged in all the time as it suggests, does having the battery constantly drop to 58% only to have it charge back to 60% hurt its lifespan more than normal?ĮDIT: I got the answer from somewhere else but I'll post it here in case anyone needs it. I couldn't find info on this specific scenario anywhere. If the battery drops to 58%, it charges back to 60%.Stops charging once it reaches 60% and continues to use AC power.From what I understand, what it does is (correct me if I'm wrong): Obviously, this isn't realistically doable, but MyASUS has an option to set the charge limit to 60%. Ultra fast charging (because of the heat)Īlso, I learned that it's best to keep the battery at around 50-60%.After doing a lot of reading about how to care for a laptop's lithium-ion battery, I now know that what reduces the lifespan of a battery the most are things like:
