I currently have an acer nitro V with a i7 5500u and a 840m (yes one of the worst gpus nvidia released in the past years lol)

New I got around 5 hours 30min out of it low brightness low power mode now I get around 3 hours
 
But it's been plugged in most of it's life around 22 hours a day for around 6 years (and most of the time not idling) I work with it then surf when I'm home then put movie playlists when I sleep. Keep in mind it hasn't had much use out of the 840m that's off 95% of the time

I think it will just start discharging at 80%, or alternatively, it will always keep the battery at 80%.
You shouldn't notice any changes, which is another advantage of this method as some laptops (like mine) will run slower when on strictly AC power.

Thanks I did not know that Acer Care Center had something like that! How exactly does it work? It wouldn't affect performance but it's fine to have it turned on all the time?
 
I can't really take out my battery since I don't want to break warranty, so it's good to know there's a feature like that.

If you ever plan on taking it anywhere then no but if you are just never taking it anywhere and literally just using it as a desktop then yea do it.

I had a Toshiba Satellite laptop that was plugged in for a good 10 years without issue, was using it as a desktop replacement.

You should plug it off when sleeping, so it doesnt waste watts or stuff
