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. Turbo Boost Switcher (free) and Turbo Boost Switcher Pro ($9.95).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. Since implementing the regimen I’ve described, my battery life has gone from under 4 hours to better than 5 hours! If you wish your MacBook battery lasted longer between charges, give the regimen a try-because it works!
