What happens to Mac on Low Power mode?
Low Power mode for Macs, like iPhone’s Low Power mode, optimises battery life by altering your device’s energy utilisation. It reduces screen brightness, slows the system clock, and disables non-essential background tasks. A Mac in Low Power mode will run more silently due to the reduced CPU speed and energy usage.
While it provides more juice to keep your Mac running, it does not address any existing battery depletion concerns on your Mac. It’s also a good idea to check your MacBook’s Battery Health to see whether it needs to be replaced.
