Would limiting maximum charge to 80% affect performance

[Walnut_Icecream]

I own a HP Victus laptop and I want to limit the maximum battery charging to 80% but I'm worried that if i do that upon reaching 80% my laptop will switch to battery mode affecting performance as laptops perform worse on battery. While I'm pretty sure it will still draw power from the charger and not the battery I'm still not certain about it. So i guess basically my question is when it reaches 80% will it draw power from the battery or the charger? Any insight on this matter I will greatly appreciate.

When operating from the mains, the notebook should also run on mains power; if it were to run on a battery, the battery charge would drop again.
