"Android's heart is also configurable if you're root"

SetCPU allows you to change CPU settings in your Android (overclock and underclock) in order to improve its performance and save battery

SetCPU permits to create profiles to change the CPU speed under certain conditions. The goal is to adapt its performance to different situation: when is charging, when you're surfing, when you're playing 3D games... and so on. Because the CPU doesn't need to fully work all the time, you can save battery and resources just by adjusting it to what it needs every time. You can set up profiles to your liking.

The most of your profiles will be about underclocking (that's it, decreasing the CPU powerful) to extend battery-life. However, you can also accelerate the processor (overclocking) to perform multitasking or those apps that needs high resources consumption.

SetCPU for Root Users has been developed by MichaelHuang, a promising developer who has just launched two apps on market, but who's reaching great success thanks to this app.

If you're root and advanced Android user, SetCPU brings you one of the best tools to control the resources usage and the battery consumption on your Android, by overclocking and underclocking. It's a pity there isn't a trial, because if it was many more users will be hooked up since it's a really great app.

Developer's original description available here
SetCPU is a tool for changing the CPU settings on a rooted Android phone or tablet. SetCPU works with a great variety of Android devices and ROMs, including the HTC One series, Samsung Galaxy series, and Nexus devices. You're under control: SetCPU can improve your performance, save battery, or both!

Automate SetCPU with profiles! SetCPU allows you to set up powerful profiles to change your settings under certain conditions, such as what app is running, 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 Android beginners and enthusiasts alike. Accelerate your processor to unleash your phone's true multitasking potential, or dial your CPU's speed down to save battery.

SetCPU also includes a "voltage control" menu, available to certain devices with custom kernels that support it, to control undervolting to save even more battery. Undervolting is only available for certain kernels.

Hey guys! It's good to be back ;) I have been very busy with school for the past year. 3.1.0 is mostly a bug fix release for some standing issues, but expect much more frequent updates from now on.

- Added SUPERUSER permission.
- Fixed a bug where action bar menu items would sometimes not appear for the profiles menu.
- Fixed a bug where voltage items would appear in reverse with some custom kernels.
- Added an open source licenses menu item in About.

Root: SetCPU needs root permissions to modify the CPU speed and other settings.

Read logs: is used for efficient app condition checking. That is currently all it's used for.

Start at boot: SetCPU will start a profiles service at boot, if enabled. It also sets default boot settings, if enabled. SetCPU does not run in the background if profiles are not enabled, and becomes inactive after settings, if any, are applied.

Wake lock: This prevents the phone from sleeping while stress testing and benchmarking.

Write external storage: SetCPU needs to read from and write to the SD card or internal storage to back up profiles.

Read phone state: The "in call" condition needs this to determine if the user is making a phone call or not, and trigger the profile if the user wants to.

Recently changed in this version

- Added support for wireless chargers in profiles.
- Fixed more voltage bugs.
- Multicore control menu coming soon!

- Hopefully fixed the voltage issues this time.

    Can't change CPU beyond 200mhz and 1200mhz on my S2. Even when adding a custom text file, and I set it to overclocked numbers, it never goes past 1200. I can already do all this in the settings menu of the device. This app has no use.

    I achieved 80% battery life, and that's after an 8 hour shift. I set my "screen off" cpu to near minimum, and my overall cpu to 600. All I can say is "amazing"
