T-Mobile SGS2 Script Disables Spare Cores with Screen Off

CPU Sleep

Improvements in technology always bring new challenges to developers. Of course, improving technology can bring rehashes of previous challenges to solve once again. One such challenge is battery life. With the release of dual core and quad core phones, the additional cores present a double edged sword. Multiple cores improve performance in certain situations dramatically, but most of the time they also require more power to operate. Taming the multi-core processors to provide better battery life has been the challenge for quite some time now, and many devices have solutions. Now, the T-Mobile Samsung Galaxy S II has one as well.

The script, which was written by XDA Recognized Developer eugene373 helps improve battery life by turning one of the two cores of the T-Mobile Galaxy S II off when the screen turns off. This lowers power consumption while screen is off, without compromising performance when the screen is on. The only drawback is that it’s only compatible with AOSP-based ROMs for the T-Mobile Galaxy S II. This means users running stock software won’t be able to use it.
