If you’ve got an Android-powered phone and have rooted it (temp root should work just fine) with this sweet little app you can not only overclock your phone, but you can underclock it, too!
“Clocking” in this context, for those of you who don’t know, is setting the speed at which your CPU runs. Making it run faster than default is overclocking, and making it run slower than default is underclocking.
Overclocking generally makes your device faster, but at the cost of battery life, heat-buildup, and the possibility of instability and shorter component life.
Underclocking generally makes your device run slower, but also cooler, and with less drain on the battery.
Combining these together can result in the best of both worlds: a faster device, with more battery life.
How do we do all that? Take a look at the video. It all starts with a US$1.99 app from the Android Market called Set CPU for Root Users. Download it, install it, and start having some fun.
To get the battery-life advantages you’ll want to set up some profiles that underclock your phone while your screen is turned off, when it starts getting hot, and when your battery starts getting low.
There’s a lot to cover, so the video is on the long-side, but the technical ones usually are.
