Product Description

SetCPU for Root Users – Overclocking your rooted device lets you speed up your phone’s processor when you are using it and lets you slow it down when it goes into "sleep" mode. It can either be a battery hog or battery saver.

SetCPU is a tool for changing the CPU settings (capable of overclock and underclock) on a rooted Android phone, including the Galaxy Nexus, Nexus S, Motorola Droid, Nexus One, G1, G2, Samsung Galaxy S II, myTouch 4G, Motorola Xoom, or one of many other devices to improve performance or save battery.

SetCPU also allows you to set up powerful profiles to change the CPU speed under certain conditions, such as when the phone is asleep or charging, when the battery level drops below a certain point, when the phone's temperature is too high, or during certain times of day. See the screenshots for examples of how you might set up profiles.

SetCPU's wide feature set make it useful to beginners and enthusiasts alike. Accelerate your processor to unleash your phone's multitasking potential, or dial your CPU's speed down to save battery.

Don't like to buy from Amazon. Out of date version. Otherwise a decent app. The developer also is not helpful in assisting in this matter. To think I paid to get an outdated app!!

One of the main reasons I decided to root my Droid 1. Overclocking is really easy and straightforward, as well as there being many other more advanced settings. A must have!

5.0 out of 5 stars Fantastic app! March 22, 2011
This app has been a lifesaver for my EVO. Love setting up the profiles to automatically adjust CPU based upon status. If you are rooted, this is a must!

5.0 out of 5 stars 4 hours on zeepad November 14, 2013
Verified Purchase
Was looking to get a little more than 2 hours from my zeepad, even when I was in airplane mode. Worked great on the zeepad set the hi to something less than 500Mhz and low to something less than 100Mhz, which is fine for the apps I run, (they probably would run fine on a 50Mhs win98 machine). Also set to airplane mode and backlight to minimum. Now I get about 4 hours of game playing. Along with an external battery pack I should be able to get 6-7 hours from it.

I was hoping to overclock a dog slow tablet. This didn't do that, but does do a good job keeping it running as fast as it can with the cpu's factory clock speeds.

I purchased this thinking it would give me extra options but found it did the same as the free version, so I wouldn't recommend spending anything on it.

Custom ROM needed?
You will need a custom kernel that allows voltage control. SetCPU should run on any ROM with such a kernel.

Screen Shot It? Something's wrong
SetCPU. They do need to fix the description. But both programs are great and worth your time.
