QCPUFreq Help

<h1>QCPUFreq Help</h1>

This application allows you to lower your maximum CPU speed.
<br><br>
This might be useful for some applications (like emulators), which cause your CPU to always run at full speed when it is really not required. You can save some battery power if you use such applications frequently. Please note that lowering the maximum CPU frequency does not always save battery power and is not always the best choice!<br><br>

<strong>IMPORTANT:</strong>
<ul>
 <li>Changes are lost after:</li>
 <ul>
  <li>Rebooting the device</li>
  <li>Making or receiving a call</li>
 </ul>
 If you want to change your CPU frequency or SmartReflex™ settings permanently, you need to edit <em>/etc/pmconfig</em>. Only edit this file if you know what you are doing!
 </li>
 <li>When the maximum CPU frequency is equal to the minimum CPU frequency the kernel might use the next frequency scaling step as the maximum frequency. For instance, if you set your maximum frequency to 250MHz the official kernel will actually use 500MHz as the maximum frequency. This is a kernel problem.</li>
 <li>SmartReflex™ is known to be unstable on some devices and may cause random reboots.</li>
 <li>Starting with PR 1.2, Nokia has disabled "VDD2 SR" in order to make the device more stable. This is why QCPUFreq only enables VDD1 SmartReflex™.</li>
 <li>On official kernels the CPU temperature is very unaccurate. On power kernels the temperature can be much more precise, if the <em>bq27x00_battery</em> module was loaded.</li>
 <li>The value of the CPU temperature might sometimes be "Unknown". This is yet another kernel problem and not a bug in QCPUFreq.</li>
