Dynamic Power Management (DPM) is a technology used in electronic devices to optimize power consumption. It adjusts the power usage of components based on their current activity levels. For example, when a device is idle, DPM can reduce the power supplied to certain parts, extending battery life and reducing energy costs. DPM is commonly applied in devices like smartphones, laptops, and servers. By monitoring usage patterns, DPM can turn off or lower the power of unused components, ensuring that energy is used efficiently. This not only helps in conserving energy but also enhances the overall performance of the device.
