A core reason you’d want one of the best gaming laptops is to play your favorite PC games on the go. However, your experience with AAA games won’t be great on battery power. Not only will you generally get less than two hours of gameplay, but you'll suffer severe drops in frames per second (FPS). This is why most users keep their gaming laptops plugged in during use.
But what if you’re itching to play a game and there’s no wall outlet in sight? Are you stuck playing for just a couple of hours at 30 frames per second or lower? Not necessarily, so long as you make various adjustments to the laptop and game. Though the results won't always match what you'd get when plugged in, you’ll have a smoother gaming experience.
If you want to squeeze as much performance as possible from a gaming laptop running on battery, I’ll show you how!
On battery vs plugged in
Generally, a battery provides around 40 to 90 watts of power, whereas a wall charger can provide 100 to 200+ watts. That extra power allows laptop components like the GPU and CPU to run more efficiently, delivering smoother gaming performance. However, on battery power, operating systems automatically switch to low-power or balanced profiles, which lowers frame rates and screen refresh rates.
There are also safety reasons. Drawing too much power too quickly from a battery can generate excessive heat and damage the cells. Laptops also slow the CPU and GPU on battery power to prevent overheating. When you connect a laptop to a wall outlet, your computer knows it has an endless energy supply and removes all the speed caps.
I ran Cyberpunk 2077 on the Alienware 16 (2026) on both battery power and while plugged in to show you the difference. At default graphical settings and native 2560x1600 resolution, the game ran at around 110-120 fps while I was on foot and around 90-100 fps when I drove through the city center. Unplugged, Cyberpunk 2077’s frame rate dropped to the 70s on foot and to around 55 on the highway.

To be clear, the Alienware 16 is an extremely powerful gaming laptop, which accounts for its high fps even when unplugged. Still, a 30 frames-per-second drop isn’t small and illustrates the difference between playing plugged in and unplugged.
How to get better performance on battery
I’ll now detail how to get battery gaming laptop performance while on battery. Keep in mind that the battery can’t output enough wattage for full gaming speeds, so performance will always be limited compared to when you’re plugged in. With that out of the way, let’s get into it.
On your laptop, click the battery icon on the taskbar and set the power mode to Best Performance. If your laptop has an Nvidia RTX GPU, you can disable BatteryBoost or raise the frame rate cap in the GeForce Experience app (or the Nvidia app).
Similarly, open your laptop manufacturer’s custom app (such as Asus Armoury Crate, Razer Synapse, or Lenovo Vantage) and switch the operating mode from Eco/Silent to a manual or performance profile. You can also set a custom frame limiter in the Nvidia Control Panel to limit CPU and GPU usage as needed.
To improve battery life, you can lower the refresh rate from a high rate like 144Hz to 60Hz. You can also reduce the display’s brightness to around 50% or lower and turn off RGB lighting if your laptop uses it. Unplugging unnecessary peripherals also helps improve battery life. And of course, shut down any apps you’re not currently using.
On the game side, you can do things like lower the game’s resolution, shadow quality, and graphical settings to reduce the workload on your laptop. Similarly, you can cap your maximum FPS in the game settings to keep stable performance.
Bottom line
I will always advise folks to keep their gaming laptops plugged in while playing for the best possible performance. However, if there’s nowhere to connect, the tips above should help you get better performance on battery life. It’s not as optimal as when you’re plugged in, but you’ll have a smoother overall experience.
