Android smartphone users looking for more control over their devices have been rooting their phones and using software like SetCPU to manually adjust the processor speed for years.
But now that dual, and even quad-core phones are becoming the norm, there’s another way to speed up your phone or adjust performance to improve battery life: decide how many processor cores should run at a given time.
That’s exactly what CoreControl lets you do.
CoreControl is a free app designed to let you decide whether your device should use 2, 3, or 4 cores.
Normally this is something that’s decided automatically depending on what your Android phone or tablet is doing, but that doesn’t always work out as well in practice as it does in theory — especially if you’ve got a battery that’s running out of juice and you’re willing to give up a little performance to keep it alive a little longer.
The app is designed to work with the HTC One X, but I suspect there’s a chance it could work on other devices with NVIDIA Tegra 3 quad-core processors as well.
