After the adjustment, “GPU power dropped from 14W to 3W, and the temperature gradually fell from 66°C to around 51°C,” wrote stlk0. “The laptop became cooler and quieter, and battery drain was noticeably lower.”
To help others with the same problem, Stlk0 created a free and open-source Windows utility called MacBookEco. The app lets you switch between 49Hz and 60Hz for the display. It also includes other CPU power presets. MacBookEco is available on GitHub.
Intel Macs are pretty old by now. The last Intel-series MacBook Pro was released in 2020. As time goes by, the amount of charge the MacBook battery can hold diminishes. Since Boot Camp is dead on M-series Macs, users who need to run Windows natively will do what they can to get the most out of their Intel Macs. Running hot harms the battery, so this utility could be a lifesaver for some users.
