Laptop slow without power adapter?

My HP Pavilion Gaming Laptop 15-ec0xxx is very fast when connected to the power adapter and you can play almost all games smoothly with a high graphics setting. But as soon as I disconnect it from the power supply

every game jerks so much that it is unplayable. Why is that? I have already set my energy status to best performance, but nothing has changed.

I suspect it is because the battery gives less power than the power supply.

For me it is the same, in battery mode my laptop has too little power for the graphics card, which makes games etc slower.

This is normal… Unfortunately

Gaming laptops simply have to be permanently connected to the power cable when gaming…

Here I wrote a somewhat more detailed answer on a similar topic.

This is an interesting question.

I suspect there's a problem in the graphics area

with workaround:-).

Leave the power supply on.
