So, now that you know how to undervolt your CPU, it's time to talk a bit about why you would want to. There are a number of different benefits, but most of them come down to preventing your CPU ...

A proper undervolt could, based on personal experience, take anywhere from 2-4 hours. Remember to keep your Steam Deck plugged in during testing since you'll easily consume all the battery.

It's OK to undervolt both the CPU and the GPU, but this is done separately and in different programs. If you want to tackle that next, check out our guide on how to undervolt a graphics card.

Beside the Core Voltage Offset, there will be a drop down list from which you can select the .05V increments you would like to undervolt by. Once you’ve selected, then hit Apply.
