Windows 10: Does the battery percentage of my laptop affect performance even when it's plugged in?

So I have a laptop that I use plugged in most of the time, and I use a first-party software provided by the manufacturer of the laptop to limit the charge of the battery to between 70% and 80 to lengthen the lifespan of the battery. Does this affect the laptop's performance in any way? ie. lower performance compared to being fully charged

:)

 

Laptop turns off & battery stuck at same percentage

I've followed the suggestions people posted on that thread but nothing solved the problem so far. I've made a short screenshot of the battery report which explains whats going on better:




The battery is on AC for some reason and won't charge, i've tried taking the battery out and inserting it in again while it was on AC but still no success.

 

Battery Percentage on My Laptop

Hey Team,

So I've been trying to do some of my studies throughout the day, and as my laptop battery runs out, I plug it in. However, for some reason, lately when I have plugged it in the battery percentage seems to stay the same the whole time. This didn't occur when I first used the laptop. It is an acer aspire but I do not know if it is troubles with the power cord as I have tried plugging it in at different outlets or if it is the laptop itself. The power cord has no wires open or anything like that which is why I don't understand why the battery percentage is not going up.

Thank you muchly

Make sure to install all Windows important updates.
