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

Normally when you leave home, your iPhone will lose its Wi-Fi connection and automatically choose cellular data, but it is better for users to turn this connection off and do it completely from the Settings app. This has a number of reasons, especially security purposes as stated by cybersecurity experts.

Turning off Wi-Fi on iPhone when going out will bring some benefits to users

Save battery even if not much

Perhaps the most important reason is the difference in battery consumption of the iPhone. Wherever you go, the iPhone will tend to consume a little more power when Wi-Fi is on, even if it is not connected to a network. This is mainly because the iPhone is constantly searching for a network to connect to, so it is a background process that is not always necessary. In situations where we need to save battery on the iPhone when we are away from a plug, it is a good idea to consider.

Improve device performance

Similar to the above, background processes not only cause more battery consumption but also reduce performance because the iPhone will have to allocate power across the device, so to a certain extent, avoid it. As a general rule, mobile data connections tend to be slower and even unstable, especially if you are moving through an area with poor coverage.

But the data connection is sometimes faster than any open Wi-Fi network we can find in coffee shops, shopping malls, airports, and other places. And that's not even taking into account the security issue.

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

Avoid getting your iPhone infected with malware

This is a problem that cybersecurity experts are concerned about. For example, experts at the Spanish National Cyber Security Institute (INCIBE) believe 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 cyber attacks so that they can access the browsing history, thereby obtaining confidential data that users access such as banking services... Experts say that a warning message may appear on the iPhone when we connect to an unsecured network and that should not be ignored. According to Apple's instructions, users should not connect to networks with old protocols (WPA/WPA 2, WEP, TKIP...).
