How to Completely Disable Wi-Fi on iPhone with iOS 12: All the Methods + Secret Tips

Disconnection Wi-Fi on devices with iOS 12 It seems like a simple task, but this version of the operating system has its own peculiarities. For example, many users encounter the problem that after disconnecting via Control center the module continues to work in the background - this is part of the energy saving logic AppleAs a result, the battery drains faster, and mobile network traffic is used unnecessarily.

In this article we will look at all possible ways to disable Wi-Fi on iPhone or iPad With iOS 12 — from standard to hidden. We will pay special attention complete shutdown (not just visual), as well as nuances not covered in official instructions. If you're looking for a way to save battery or avoid automatic connections to unreliable networks, you'll find the answers here.

⚠️ Attention: On devices with iOS 12 Disabling Wi-Fi via Control center This doesn't always mean physically turning off the module. The system can automatically connect to known networks for geolocation and background tasks. To avoid this, read the section about complete shutdown.

Standard methods for disabling Wi-Fi

Let's start with the most obvious methods, familiar to most users. They're suitable for temporarily disabling the network, but they don't always guarantee complete shutdown of the module.

The fastest way is to use Control center (Control Center). To do this:

1. Swipe from bottom to top (on iPhone with a button Home) or top down from the upper right corner (on models without a button) Home).
2. Find the icon Wi-Fi (antenna icon) and tap it. The icon will turn gray, indicating the network is disconnected.

However, there is a catch: iOS 12 this action is only disconnects the current connection, but doesn't disable the module completely. After a few minutes, the system may reconnect to the network automatically—for example, to update geolocation or run background app tasks.

The second standard way is through Settings:

• 📱 Open the app Settings → Wi-Fi.
• 🔄 Move the slider to the position Off (gray).
• ✅ Confirm the action if prompted.

This method is more reliable, but there is a nuance here: some system services (for example, Significant places V Privacy settings) may temporarily activate Wi-Fi to collect data. To avoid this, read the next section.

How to completely disable Wi-Fi (including background work)

If you need guaranteed to turn off Wi-Fi module - for example, to save battery or for security reasons - standard methods are not enough. In iOS 12 There are hidden settings that allow you to do this.

The most reliable way is to use Airplane mode:

• ✈️ Turn on Airplane mode V Control center or through Settings.
• 🔄 Then turn it on manually mobile network (if connection is needed), leaving Wi-Fi off.

In this case the module physically turns off, and no background processes will be able to activate it.

An alternative method is to turn it off location services for Wi-Fi:

1. Go to Settings → Privacy → Location Services → System Services.
2. Find the item Wi-Fi network and turn it off.
3. Return to Settings → Wi-Fi and turn off the network.

Now the module won't be activated for location services. However, this method doesn't block background activity from other apps that might use Wi-Fi for syncing.

Disabling automatic connection to networks

One of the most annoying features iOS 12 — automatically connecting to known networks, even if you're not actively using them. This not only drains your battery but also creates security risks (for example, connecting to fake access points).

To disable auto-connection:

1. Go to Settings → Wi-Fi.
2. Tap the blue icon ⓘ next to the network name.

4. To be on the safe side, click Forget this network (will delete all saved data).

If you want to ban iPhone connect to any open networks automatically:

• 🔒 Go to Settings → Wi-Fi.
• 🛑 Turn off the option at the bottom of the screen Request to join networks.

This won't disable Wi-Fi completely, but it will prevent unauthorized connections. This is useful if you frequently visit places with open networks (airports, cafes).

Disabling Wi-Fi for individual apps

Not everyone knows that in iOS 12 You can restrict Wi-Fi access for specific apps. This is useful if an app is using data in the background or connecting to the network without your knowledge.

For more flexible traffic management, you can use the function Limiting background activity:

• 📱 Settings → General → Content Update.
• 🔄 Disable updates for unnecessary apps or set Wi-Fi restrictions.

This will reduce battery and traffic consumption, but is not a substitute for disabling the module completely.

Problems and errors when disconnecting Wi-Fi

Even after turning off Wi-Fi, users iOS 12 Sometimes we encounter unexpected problems. Here are the most common ones and how to solve them:

If none of the methods help, try forced reboot:
