Turbo Boost Switcher can temporarily disable Turbo Boost, and I was curious to see if disabling it would meaningfully affect battery life. The advertised clock speed - 2.2 GHz for the base-model 15-inch - is only the guaranteed minimum. Modern Intel CPUs use Turbo Boost to dynamically increase CPU speed, depending on workload, up to their thermal limits. I used to eke more battery life out of my 2008 MacBook Air by underclocking and undervolting its CPU to a lower speed with CoolBook, but that’s no longer possible on modern Macs. The best battery life in the 15-inch Retina MacBook Pro line is the base model (without the high-powered GPU), but Apple’s stated 8–9 hours of battery life is only achievable with very light use - if you’re using tools like Xcode, Logic, or Lightroom, you’re lucky to get more than 4 hours. No need to update if using Mojave or any other previous version of macOS.A programmer, writer, podcaster, geek, and coffee enthusiast.Ībout Disabling Turbo Boost to get more MacBook Pro battery life The 2.9.1 contains a workaround for this.
