Can I Leave My Laptop Plugged In All The Time?

I recently bought a new laptop and was wondering about the life of the battery and if I should or should not keep the laptop plugged in all the time. My old laptop was a stationary one, so it was plugged in all the time. Towards the end of its life (6 or so years), the battery would last a little over an hour without being plugged in.



You Can't Overcharge the Laptop's Battery

According to what I read, when the laptop is plugged in and the battery reaches a 100% charge, the battery stops charging and the laptop runs off the power cable only. So there is no damage to the battery by charging it over its capacity. The issue is with overheating. If the battery gets too hot, that can certainly affect its life. Therefore it's best to remove the battery (if possible), if not, unplug the power cable. Ideally, it would be great to keep the battery at a 50% charge or somewhere between say 40-80%.


There really isn't a clear-cut answer as to whether to leave the laptop plugged in all the time or not. I've decided that I will leave mine plugged in when it is at my desk and if I think of it, I'll unplug it for a while so the battery gets a chance to be used.


A laptop's battery will wear down over time, that's a fact. But there are things you can do to prolong its life.
