This won’t be worth doing all the time, but it’s nice to have the option.Īnd I’d still like to see higher battery capacity in normal operation. The MacBook Pro also runs noticeably cooler, and gains about 25% more battery life. While AnandTech’s “Light” test appears lighter than mine, neither of us could reach Apple’s “8 hour” claim for this model, which is disappointing.ĭisabling Turbo Boost hurts performance of CPU-intensive tasks by about a third, but doesn’t significantly slow down lighter tasks. My “Heavy” numbers with Turbo Boost line up well with the very similar 2013 model in AnandTech’s “Heavy” battery test, which gives me confidence in my test. When plugged in and fully charged, I also ran the Geekbench 32-bit single- and multi-core benchmarks, and observed the power range drawn from the wall with a Kill A Watt.

Before running the test, the battery’s cycle count was just 2. ORDER TOLL FREE 9 US & CANADA 80 ORDERS &. I ran this test at 50% brightness (with auto-adjustment disabled), no keyboard illumination, and sound muted until the battery ran out and it shut down.

For the moderately heavy load, the cycle also includes a clean and full compile of Overcast’s iOS app using xcodebuild every few minutes. I devised a simple battery-testing script to simulate light and moderately heavy loads on my brand new, mid-2014-generation, base-model 15-inch Retina MacBook Pro: it loads some popular websites in Safari over Wi-Fi, spending some time scrolling down each one, while playing music in iTunes, then appends the time and battery status to a file in Dropbox, which promptly gets synced. 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.
