FAQ: Answers to Frequently Asked Questions

Is it possible to turn off Wi-Fi on iPhone permanently so that it never turns on?

Technically, no. iOS always leaves the option to turn on Wi-Fi for critical functions (updates, AirDrop, Find My). However, you can:

• Disable the Wi-Fi scanner in privacy settings.
• Use Airplane mode with only mobile Internet enabled.
• Delete all saved networks and disable auto-connection.

This will make the device behave as close to a "complete shutdown" as possible.

Why did Wi-Fi start turning on by itself again after updating iOS?

Apple sometimes resets user settings for network functions after major updates (for example, when switching from iOS 16 on iOS 17). To avoid this:

• Before updating, please backup your settings via iCloud or iTunes.
• After updating, check your settings Wi-Fi And Wi-Fi scanner.
• If the settings have reset, repeat all the steps in this article.

Will turning off Wi-Fi save battery life?

Yes, but the effect depends on how you use the device:

• Without active use: Savings will amount to ~5–10% of the charge per day (due to disabling background scanning).
• With active use: If you often run applications that require the Internet (social networks, instant messengers, navigators), the savings will be minimal, since iPhone will use the mobile network.
• In standby mode: Turning off Wi-Fi can extend battery life by 15-20%, especially if you sleep with your device on.

For maximum savings, combine turning off Wi-Fi with Low power mode.
