Software CPU Overclocking on Apple iPhone and iPod

If you didn't know, Apple artificially limits the performance of the processors for their mobile devices. The nominal processor frequency for 3G is 600 MHz, and for 3G (s) 833 MHz.
In fact, the processors operate at 412 and 600 MHz, respectively. Those. one and a half times lower .

There is an easy way to programmatically remove this limitation.

After overclocking, your device will indeed work much faster , but, like any overclocking, you do it at your own peril and risk. Acceleration is possible only on jailbroken devices.

Instructions for overclocking the processor for the iPhone and iPod touch

1. Run the shell, go to the folder: /System/Library/SystemConfiguration/PowerManagement.bundle/
2. You will see the file “ com.apple.SystemPowerProfileDefaults.plist ”
3. Rename it, for example, to the following: “ com.apple.SystemPowerProfileDefaultsBAK.plist ”
4. Reboot the device.

Increasing the processor speed is likely to lead to increased battery consumption and heating of the device. Remember, you do everything at your own peril and risk, be careful!

I implemented this procedure on my 3G and note that the increase in speed is very noticeable, especially in heavy applications. Cydia loads and responds to everything one and a half times faster, the overall comfort of work has increased markedly. Regarding battery consumption and heating, while the statistics are not collected.

Good luck and be careful.
