Question Battery settings in Dell laptop

[pokelto3]

Hi,

I've recently bought a new laptop (Dell G15) and I mostly keep it on my desk plugged in. I have a question about battery: should I use Custom setting (right now it starts charging at 50% and ends at 80%) or Always AC?

Also: what setting is the best choice while gaming?
