This ratio holds for most other configurations: the gain in battery life is about as large as the loss in heavy-workload performance. It roughly doubles compilation times, but also doubles the battery life. This is an extreme option, but one I’d occasionally take if offered. It’s impressive how much faster this new 13-inch model is than the best laptop ever made due to significant CPU and SSD improvements.ĭropping the wattage to 6W, the thermal limit of the fanless 12-inch MacBook, interestingly (but not surprisingly) makes it perform effectively identically to the best 12-inch MacBook in Geekbench. Improvements are in green and performance reductions are in red:ġ5-inch 2015 MacBook Pro (2.2 GHz quad-core i7) My test was based on the “Heavy” script from last time, but using xcodebuild every few minutes with Overcast’s current codebase (which is larger and includes some Swift). Over the last few days, I’ve run battery tests on my 2018 13-inch MacBook Pro with the (awesome) 2.7 GHz i7 and my 2015 2.2 GHz 15-inch 3 to see how far I could push the battery life using Volta, which can disable Turbo Boost and/or set wattage limits on the CPU. Since then, I’ve been running Turbo Boost Switcher Pro to automatically disable Turbo Boost when I’m running on battery power, and it has been wonderful: I made it through that 8-hour flight only because Turbo Boost was off. Reduce the processor’s maximum wattage or disable Turbo Boostīack in 2015, I experimented with disabling Turbo Boost and discovered that it reduced performance by about a third, but also boosted battery life by almost as much.Let third-party apps detect Low Power Mode and reduce their background operations to only essential work.Auto-dim the screen after a shorter time.Don’t download or install software updates.Reduce the frequency of Time Machine backups.Disable the discrete GPU on 15-inch models unless required for hardware reasons 2.There’s no such feature on Mac laptops, but there should be. Sometimes, you just need Low Power Mode: the switch added to iOS a few years ago to conserve battery life when you need it, at the expense of full performance and background tasks. But sometimes you lose that lottery, as I did on my latest 8-hour daytime flight.Īpple’s “Up to 10 hours” claim doesn’t apply to my work, 1 which is usually a mix of Xcode, web browsing, and social time-wasting, so I knew I’d have to seriously conserve power. Laptop battery life is decreasingly relevant to me as more airplanes offer power outlets.

Don’t forget to re-enable Turbo Boost on the Mac (Book) to get full performance again. So your mileage can vary, it really depends on how you use the Mac. The MacBook Pro also runs noticeably cooler and gets about 25% longer battery life. ![]() According to who ran some benchmark tests, “Disabling Turbo Boost decreases CPU-intensive tasks by about a third, but does not slow down lighter tasks significantly. ![]() Whether that’s worth the tradeoff or not depends on your usage scenario, but in certain situations where performance is less important than a longer-lasting battery, it can be helpful.Īnecdotally, I noticed a nearly an hour increase in potential battery life when using the app to disable Turbo Boost on a new model MacBook Pro, but some users have reported more dramatic changes. ![]() In others words, if you turn off Turbo Boost, your Mac battery may last longer, but the computer will be noticeably slower. Does disabling Turbo Boost help battery life?ĭepending on usage, yes possible, but at the expense of overall computer performance. This will remove the kernel extension that the feature of work.
