The three reasons why you should always turn off your phone's Wi-Fi when leaving home
Keeping Wi-Fi active when leaving home is a risky habit. What serious problems it can cause.
The WiFi technology makes it possible to connect wireless devices to the Internet and facilitates everyone's life. However, having it activated on your mobile phone when leaving home can be the source of serious inconveniences, both for security and for the device's performance. In the following paragraphs, the three main reasons to deactivate WiFi when leaving home and generally activate the connection via mobile data (4G or 5G).
1. Data protection
Whenever WiFi is active, the mobile phone constantly searches for available networks to connect to. And if there is an open network without a password, it connects. This can pose a significant security risk because some networks may be fake or malicious, created by people trying to steal personal data or infect the device with malware. For this reason, it is advisable to deactivate WiFi when outside the home and only connect to trusted and secure networks, such as those at home, work, or public places with security certification.
2. Battery life of the device
Another reason to deactivate WiFi when leaving home is to extend the battery life of the mobile phone. Keeping the wireless connection always available consumes energy unnecessarily, as the device is constantly sending and receiving radio signals. This can cause the phone's battery to drain faster.
3. Mobile performance
If Wi-Fi is always active and searching for networks, the smartphone's microchips work hard. As mentioned earlier, this can affect battery life, but it also means less processing power for other tasks the user wants to perform. Additionally, Wi-Fi can interfere with other radio signals, such as those from the mobile network or GPS, and affect the quality of the connection or browsing. Therefore, it is advisable to deactivate WiFi when it is not needed or when using another method of connection.
Turning off the mobile Wi-Fi, a good habit
Ultimately, deactivating the mobile phone's WiFi network when leaving home can have several benefits, both for security and for the device's performance. This does not mean that one has to give up WiFi completely, but rather that it should be used with caution and only when necessary. In this way, it is possible to enjoy a better experience with the mobile phone.
