How Does Wi-Fi Use Affect Computer Battery Life?
How Does Wi-Fi Use Affect Computer Battery Life?The Wi-Fi network protocol requires power (electricity) to operate the radios used to send and receive data. How exactly does your usage of Wi-Fi affect a computer’s power consumption, specifically the life of battery-operated devices?Answer: The power required by a Wi-Fi radio is measured in decibel millwatts (dBm). Wi-Fi radios with higher dBM ratings tend to have greater reach (signal range) but will generally utilize more power than those with lower dBM ratings. Wi-Fi consumes power whenever the radio is on. With older Wi-Fi network adapters, the amount of power used is generally independent of the volume of network traffic sent or received, as these systems keep the Wi-Fi radio powered at
