i have a asus laptop windows 11Welcome to the forums, newcomer!
Make and model of your laptop? An SKU would help us two fold. Maybe see if your power plan is set to power saving when on battery mode.
well when i go into power plan i only see balanced and asus recommended, there is no high or ultimate performance or anything else. And no hidden other options.Most laptops will default to a lower power profile when on battery. You will need to alter the power plan in order to get more performance. The trade off will be MUCH shorter battery life, in some cases as little as 20 or 30 minutes. If this is a gaming laptop with a discreet GPU the it is generally accepted that it will be plugged into the mains when gaming.
