Automatically disable Turbo Boost when battery level goes below a configurable setting.Automatically disable Turbo Boost when the charger is disconnected For instance, if you have the 2011 MacBook Air with the 1.6 GHz Core i5 (as detailed in this AnandTech article), the Turbo Ratio is set to 0047.Fully customize the status bar to show temp, fan speed, etc., have the Turbo Boost.Main features: - Visually know if Turbo Boost is enabled or disabled at any time. For $9.95 (which includes free updates, forever!) you’ll be able to: Sparked by rumors of a performance-enhancing Pro Mode for the Mac, developer and podcaster Marco Arment is calling on Apple to introduce a Low Power Mode for Mac laptops. Turbo Boost Switcher is a little application for Mac computers that allows to enable and/or disable the Turbo Boost feature. Turbo Boost Switcher is free for basic use, and the Pro version offers several nice features. I’ve been turning off Turbo Boost off for pretty much everything except when I’m working in Adobe apps and haven’t even noticed the difference in Safari, Mail, office apps, and other small apps and utilities I use regularly. In my use, I’ve noticed an increase in battery life of around an hour or so, and the bottom of the laptop doesn’t get hot at all. Lowering the temperature of your processor helps preserve its overall life (heat kills), so even if battery life isn’t an issue for you, the app can still serve the purpose of protecting your investment! Since the app shows you the statistics, it’s easy to see what it will do for you. Reviews of the app claim up to a 25% increase in battery life. To get an idea of the sorts of things that might be throttled in a macOS Low Power Mode, check out the long list compiled by Arment.If you have a modern MacBook or MacBook Pro that offers Turbo Boost -a feature that allows your MacBook’s processor to speed-up when under heavy load, it’s nice to get the speed boost, but it also heats up your Mac and drains your battery at a more rapid pace.Įnter Turbo Boost Switcher, a nifty little menubar utility that allows you to turn off the processor’s Turbo Boost feature whenever you wish.Īlong with turning on and off Turbo Boost, this handy little utility also shows you the CPU load, fan speed, and temperature. ![]() However, I’m with Arment – I’d prefer to run an iOS-like Low Power Mode for Macs that is implemented at the OS level and makes intelligent choices about what activities to stop or slow down. Running an app like Turbo Boost Switcher is worth considering when you have work to get done because it can mean the difference between your MacBook’s battery making it through a long flight or not. ![]() Single-threaded performance hurts more than with wattage-limiting, but it’s able to maintain better multi-threaded performance and more consistent thermals, and gets a larger battery gain relative to its performance loss. The best bang-for-the-buck option is still to just disable Turbo Boost. That’s a trade-off I’d gladly make when I need to maximize runtime. The gain in battery life is about as large as the loss in heavy-workload performance. ![]() This time around, he replicated disabling Turbo Boost on his 2015 MacBook, but on his 2018 model, he also limited the laptop’s power consumption using Volta.īased on the results Arment concludes that: In 2015, Arment used an app called Turbo Boost Switcher to disable Turbo Boost on his laptop. Marco Arment has revisited MacBook Pro battery life tests that he first ran in 2015 to see how his new 2018 13-inch MacBook Pro with a 2.7 GHz i7 processor and his 2015 2.2 GHz 15-inch MacBook Pro would fare under similar conditions.
