Reasons to turn off Wi-Fi on iPhone when leaving home

Normally, when leaving home, the iPhone will lose its Wi-Fi connection and automatically switch to cellular data, but it's best for users to turn this connection off completely from the Settings app. There are several reasons for this, especially for security purposes, as stated by cybersecurity experts.

Turning off Wi-Fi on your iPhone when you're out and about offers several benefits to users.

Saves battery power, even if not significantly.

Perhaps the most important reason is the difference in iPhone battery consumption. Wherever you go, the iPhone will tend to consume slightly more power when Wi-Fi is on, even without a network connection. This is mainly because the iPhone is constantly searching for a network to connect to, a background process that isn't always necessary. In situations where we need to save battery on the iPhone while far from a power outlet, this is an idea worth considering.

Improve device performance

Similarly, background processes not only cause greater battery consumption but also reduce performance because the iPhone will have to allocate power across the device, so to a certain extent, avoid them. As a general rule, mobile data connections tend to be slower and even unstable, especially when moving through areas with poor coverage.

But the data connection is sometimes faster than any open Wi-Fi network we might find in cafes, shopping malls, airports, and other places. This doesn't even take security into account.

iPhone performance can also be improved by turning off Wi-Fi.

Avoid getting your iPhone infected with malware.

This is a concern for cybersecurity experts. For example, experts at the Spanish National Institute for Cybersecurity (INCIBE) argue that public Wi-Fi networks are often vulnerable to attacks. Of course, the iPhone is a very secure device, but exposing it to a public network means opening the door for cyberattacks to access browsing history and potentially steal confidential data, such as banking information. Experts say a warning message may appear on the iPhone when connecting to an insecure network, and this should not be ignored. According to Apple's guidelines, users should avoid connecting to networks using outdated protocols (WPA/WPA2, WEP, TKIP, etc.).
