WiFi devices that are always on can consume power to a certain extent, but how much power is actually consumed depends on many factors, such as the type of device, time of use, and ambient temperature. Here are some estimates for reference:
- Router: Generally consumes a small amount of power, but depending on the model and usage, the power consumption per hour may be between 0.1-0.5 degrees.
- Mobile phone: If the phone is set as a WiFi hotspot, then the power consumption will be more than the normal use of WiFi, the power consumption per hour may be between 0.1-0.2 degrees.
Tablets: Similar to mobile phones, if the tablet is set as a WiFi hotspot, the power consumption per hour may also be between 0.1-0.2 degrees.
It should be noted that the power consumption of the WiFi device itself is not very obvious, and the proportion of household electricity consumption is relatively small. Therefore, do not turn off WiFi devices often because you are concerned about the electricity bill, which will lead to unnecessary inconvenience. If you want to further reduce household electricity consumption, you can pay attention to other high-power equipment, and adjust the use of habits and time.
0.108 to 0.288 KWH
If the unit price of electricity is 0.5 yuan\/KWH to calculate, then the 9V2A router a month's electricity is 6.48 yuan, but most people's home routers are not up to 9V2A, and under normal circumstances the power is between 3-7W, calculated, the monthly power consumption is between 1.2 yuan and 2.8 yuan.
It uses very little power. If the phone is always connected to the wifi Internet, there will be no large power consumption. Rather than using data, mobile phones constantly grab mobile cellular data, wifi is more power-efficient.
Leaving wifi on consumes a certain amount of power.
1. Connecting to Wi-Fi requires power to drive, and if Wi-Fi is always enabled, it consumes power all the time.
2. Power consumption is related to the length of use time and the health status of mobile phone power, and has certain variability. 3. If you use more traffic, you may actually use more power, because Wi-Fi reduces the power requirement to access the Internet, thus reducing consumption. To sum up, using Wi-Fi consumes a certain amount of power, but whether it is excessive needs to be considered in specific circumstances.
