A few years ago, Apple introduced a feature that “saved the life” of many iPhones and iPad users around the world – especially those who like to, say, live dangerously and / or away from outlets.
THE Low Power Mode (Low Power Mode) turn off some connectivity options on the device and tell the processor to lower the ball to give those extra minutes you need to call an Uber, check an information or even roll some more tweets on your device. But will Macs also deserve something like that?
That’s the developer’s idea Marco Arment, who wrote an article on his blog with several very convincing arguments talking about such a possibility.
According to Arment, a Low Energy Mode on macOS would work on some fronts: it would turn off the dedicated GPU on models equipped with one (except for tasks where they are needed, such as connecting to an external monitor), pausing synchronization / photo analysis and Spotlight indexing, would reduce the frequency of backups and would not install or download updates or content from iTunes and the App Store. In addition, third-party applications could detect when the mode was active and thereby reduce its background activity for essential tasks only.
The most important point of the possible tool, however, would be on the machines’ own processor: a Low Energy Mode that values itself on the Mac would, according to Arment, turn off the mode Turbo Boost Intel chips and reduce their maximum power. Using the Volta application, the developer did some tests with his Macs, recording the battery time with the processor running normally or with performance restrictions.
See the results:
Obviously, restrictions make your Mac run more slowly – just see, in the last column of the tables above, how long it took Macs in each scenario to run a particular script used by Arment. Still, the developer stated that this would be a trade-off he would happily do in times of low battery and no power outlets around – and I believe many would agree with him.
While Apple does not introduce its own solution to the issue (if it ever will, that is), Arment recommended that users concerned about their batteries use the Turbo Boost Switcher Pro app, which turns off peak performance on Intel processors to save those very important tenths of battery for the next hours of work.
