My new laptop (a Lenovo) comes with a software that allows to limit the charge of the battery to a set ceiling. It says that this allows to prolongate battery life. Intrigued by this claim, I googled and found out that for Li-ion batteries that equip modern laptops and smartphones, it's indeed true.
" Roughly speaking, every 0.1V decrease in cell voltage doubles the cycle life, according to Battery University. "

So it is recommended that unless you are going on a trip or on a live show solely on battery, you should avoid charging your devices above 80%, or even 70%. Ideally, the charge level should stay in the 20-70% range. Unfortunately, Windows doesn't limit the maximum charge so you will need a specific driver for that.
The other factor that reduces battery life is heat. They don't like temperatures above 30°C so make sure to keep the laptop cool.
