In windows 10 laptops we can reduce battery consumption by limiting the processor frequency. Processor frequency means the operating frequency of the CPU’s core(s) in MHz. The higher the frequency is for a CPU, the faster the processor is. You can specify the approximate maximum frequency (in MHz) of your processor from within Windows 10 to limit the frequency if needed. This video will guide you to achieving the following states.
