You’re familiar with low power mode on iPhone (and iPad and Mac), which temporarily disables some features to save battery life. But did you know about high power mode, the polar opposite to low power mode?

And:

To help you squeeze the last drop of power from your Mac’s Apple CPU, the new 16-inch MacBook Pro provides a new feature, dubbed High Power Mode. When you put your Mac into high power mode, the operating system will maximize performance during very intensive workloads by permitting the fans to run at higher speeds to keep the CPU cool.

From Apple’s official support document:

Your MacBook Pro has multiple energy modes you can switch between. By default, your Mac is set to Automatic mode to balance energy use and performance. Low Power Mode reduces energy use to increase battery life. On the 16-inch MacBook Pro with M1 Max, High Power Mode allows the fans to run at higher speeds. The additional cooling capacity may allow the system to deliver higher performance in very intensive workloads.

Check out the images in the Apple Support document to see how to turn High Power Mode on and how to tell if it is on from the menu bar.

Yes, this feature is limited to the 16″ MacBook Pro M1 Max, but I suspect it’ll become more mainstream as Apple expands it’s M1 product line. Good to know about.
