Is it worth to turn off the Wi-Fi-module of the laptop to save energy
Wireless laptop interfaces give us freedomfrom the wires. But for freedom this has to be paid: the laptop's battery life with Wi-Fi enabled is reduced. But how much strongly does this module affect the power consumption of the laptop and should it be turned off Wi-Fi when we do not use it?
Instructions
1
Power consumption of Wi-Fi chips for the last 2-3 yearsyear has decreased very significantly. If your laptop is released in the last 2-3 years, then you have nothing to worry about. In idle time, these new chips practically do not consume anything.

In relatively old models, the difference betweenpower consumption of a laptop with Wi-Fi on and without it. In a simple measurement conducted by the users themselves, the wireless module can consume about 250 mA. In terms of 12 V, the voltage is 3 watts. And with active use, this difference increases to 7 watts.

Is this a lot or a little? The average consumption of a working laptop is about 45 W, and the active one can be over 60-65 W. At the same time, the share of the processor accounts for 80-90% of the capacity.

So the significant role of turning off Wi-Fi inThe idle time will not play, even if you have a fairly old laptop. But if you want to maximize the battery life of your laptop, and the account goes for minutes, then boldly turn off - 20-30 minutes of saved time are guaranteed to you.
