I'm mainly using this laptop as a desktop replacement since I do not have to bring this laptop very often, but still do need once in a while. That being said, it's usually plugged in to the wall and in some cases where I forget to unplug it, it will charge to 100% then trickle charge. This is definitely not good if I plan to maximize the battery life span by one or two more years from the intended age. There is a way to basically limit the charge to a certain percentage and it will charge again after it hits a certain percentage (e.g. charge up to 80% then wait until it hits 45% before continuing to charge again) in rooted android. Sadly, I have found no app that works like that for my laptop. If anyone know any it'd be a great help. Thanks.
