Low power mode for Mac laptops

Marco Arment:

Modern hardware constantly pushes thermal and power limits, trying to strike a balance that minimizes noise and heat while maximizing performance and battery life.


Apple’s customers don’t usually have control over these balances, and they’re usually fixed at design time with little opportunity to adapt to changing circumstances or customer priorities.

The sole exception, Low Power Mode on iOS, seems to be a huge hit: by offering a single toggle that chooses a different balance, people are able to greatly extend their battery life when they know they’ll need it.

Mac laptops need Low Power Mode, too.

Marco digs into the benefits of disabling Turbo Boost, in effect, offering a low power mode that helps your MacBook run significantly cooler, likely extending battery life as a result.
