You have to remove Wi-Fi from your smartphone when you don't need it, here's why

Removing Wi-Fi from your smartphone when you don't need it can make the difference.
In fact, one of the riskiest and most underestimated practices is leaving Wi-Fi active when it is not necessary, a seemingly harmless gesture but which can expose devices to serious vulnerabilities.
The risk of leaving Wi-Fi turned on is that you will automatically connect to unknown wireless networks.
Not only that, it also adds damage to the battery.
In fact, leaving Wi-Fi turned on involves a constant search for the network.
Between traps for personal data and consequences for the battery, leaving Wi-Fi active is therefore dangerous and useless.
The solution, however, is simple.

There are mainly two reasons: battery security In the absence of an available Wi-Fi network, the device constantly searches for a wireless network to connect to.
When you are away from home, the search uses up the battery unnecessarily, ruining it.
It must be said that most modern smartphones do not consume a significant amount of energy for this function.
The truly dangerous aspect, however, is another, namely that of safety.
Unknown wireless networks are “data traps” because connecting to them unintentionally shares your phone's information with potential hackers.

The first step is therefore to disable the Wi-Fi search, but to ensure that you stop any data leak attempts, you must also remove the connections you have connected to in the past, except the essential ones.
In fact, the fewer networks you have memorized, the less risk there will be of exposing your data.
Protecting personal data on your smartphone is therefore essential to preserving your privacy and security.
To do this you can use secure passwords, a PIN or a fingerprint and avoid trivial combinations.
It is therefore better to use a complex sequence of numbers, letters and special characters and never use those that are too common.
Keeping your smartphone's operating system and installed applications up to date also has positive effects.
In fact, updates often include security patches that correct the most known vulnerabilities.
However, the most effective method is to use a VPN, which is a virtual private network (VPN) that creates an encrypted tunnel between the device and the internet, protecting data from prying eyes.
Using a VPN when connecting to public or unsecured Wi-Fi networks is therefore essential.

For example, you can decide which apps to give permission to access personal data.
Granting permissions only to the features necessary for the correct functioning of the app allows you to limit the damage of a data leak.
Other helpful tips include considering installing an antivirus or mobile security application and avoiding unsecure Wi-Fi networks.
