The current MacBook Pro 15-inch Apple says will have a term of 8 to 9 hours – but this Who can even in very low use in reality hardly reach. The small program TurboBoost Switcher to remedy, by deactivating the Turbo Boost feature of the Intel processor. This ensures significantly longer battery life has a programmer determined in a test. Positive side effect: The MacBook is no longer so hot
Programmers Marco Arment has the program Turbo Boost Switcher made, designed to increase the battery life of the MacBook Pro significantly with Intel new processors with Turbo Boost, in which it. the variable frequency adjustment of the CPU off. The i7 quad-core processor in the 15er MacBook Pro has a base clock of 2.2 GHz, Turbo Boost can be increased to up to 3.4 GHz. This adjustment is performed by the processor in the context of its thermal management alone – it is too hot, it is clocked down
The application Turbo Boost Switcher can switch off the Up overclocking the processor temporarily when the power is not needed.. The application is available in the basic version for free and will appear in the menu bar.
Arment tested with a script whether the Turbo Boost Switcher anything brings and scored at the 15er MacBook Pro with Retina display of mid-2014 a significant extending the battery life when a small load is generated, such as WLAN, surfing, web page scrolling and iTunes music playback as well as some activity with Dropbox. This low stress (50 percent screen brightness and unlit keyboard) has been generated with and without Turbo Boost and tested the duration of Mac. In the normal configuration of the Mac was 5:40 hours, decanted with turbo boost he was proud 7:07 hours. What is also not negligible: The peak temperature was without optimizations at 90 degrees Celsius, with Turbo Boost disabled at just 60 degrees Celsius
Of course, the Mac is no longer quite so quickly – the power to go. around one-third, but in many applications you need this at all.
The Turbo Boost Switcher is free in its basic version. The Pro version for around $ 10 automatically turns Turbo Boost when required on and off – but that’s our experience not necessary. In the Pro version, there is also a setting that Turbo Boost turns on when certain applications are running. This can be set manually in a list.
