How to completely delete Wi-Fi settings on your smartphone: instructions for Android and iOS

Saved networks Wi-Fi Over time, your phone accumulates hotspots: home, work, hotel, and public. Many of them become outdated, have their passwords changed, or become unnecessary, but continue to take up space on the device's memory. Moreover, Android And iOS Automatically connect to saved networks, even if their signal is weak or they are no longer relevant. This can lead to internet issues, IP address conflicts, or security leaks.

Removing unnecessary networks Wi-Fi — a simple but important procedure. It not only helps free up memory, but also improves connection stability, prevents automatic switching to unreliable access points, and protects personal data from leaks over outdated or public networks. In this article, you'll find Universal instructions for all versions of Android and iOS, including hidden features and solutions to common errors.

If you've never cleaned out your phone's network list, you've likely accumulated dozens of hotspots—from cafes, airports, and hotels. Some of these can be potentially dangerous, especially if you've used open, unencrypted networks. Regularly cleaning out your network will help you avoid automatically connecting to untrusted internet sources.

Why you should delete old Wi-Fi networks

Smartphones remember every network they've ever connected to—this is convenient, but not always secure. Here are the key reasons why you should regularly clear this list:

• 🔒 Security: Old networks (especially public ones) can be vulnerable to evil twin attacks (Evil Twin), when scammers create a fake access point with the same name.
• 📶 Connection stability: The device may be clinging to a weak signal from a saved network instead of a stronger new one.
• 🗄️ Memory optimization: On Android network data is stored in a file wpa_supplicant.conf, which grows over time.
• 🔄 IP conflicts: When reconnecting to a network with the same name but a different router (for example, in a hotel), DHCP errors may occur.

It's especially critical to remove networks that you no longer use but that have priority over your current ones. For example, if your phone has remembered Starbucks_WiFi Three years ago, it could automatically connect to it instead of your home router if the cafe's signal was stronger.

On iPhone The problem is exacerbated by iOS's aggressive caching of networks to speed up connections. This can lead to delays when searching for new access points if the list is overloaded.

3. Select Wi-Fi.
4. Click on the name of the desired network in the list of saved ones.
5. Tap Delete (or Forget the network).
6. Confirm the action.

On some devices (eg. Xiaomi) you may need to additionally click on the three dots in the upper right corner and select Additional functionsto see the full list of networks.

Long tap on the network name|Click "Forget network"|Confirm deletion|Check disappearance from the list-->

If you use Android 12+, there is a quick way through the notification panel:

1. Swipe down from the top of the screen to open the notification panel.
2. Long press the icon Wi-Fi.
3. In the menu that opens, select the desired network and click Forget.

⚠️ Attention: On some firmware (for example, Flyme from MeizuAfter deleting a network, your phone may temporarily "forget" the current connection. Restart your device if the internet connection is lost.

Wi-Fi deletion features on different Android versions

Manufacturers often modify the standard interface. Android, so the process may vary. The table below shows the key differences for popular brands:

On devices with Android 10 and older there is a hidden function to reset all networks through ADBThis is useful if the list is filled with hundreds of points (for example, after frequent use of public transportation). Commands for resetting:

adb shell pm clear com.android.providers.settings
adb shell settings delete global wifi_networks_history

⚠️ Attention: Usage ADB Requires USB debugging to be enabled and may reset other network settings (such as VPN). Backups are recommended.

Deleting Wi-Fi networks on iPhone and iPad

IN iOS The process is more standardized because Apple tightly controls the interface. To delete a network on iPhone or iPad:

1. Open Settings.
2. Go to Wi-Fi.
3. Click on the blue icon i next to the network name.
4. Tap Forget this network.
5. Confirm the action.

Unlike Android, on iOS There's no bulk deletion option—networks must be deleted one by one. However, there is a workaround by resetting network settings (we'll discuss it below).

If you use iOS 17+, a network prioritization feature has been added. Now you can manually specify which network to connect to first, reducing the need to uninstall. To do this:

1. Tap and hold the network name in the list Wi-Fi.
2. Drag it up or down to change the priority.

⚠️ Attention: On iPhone with jailbreak, deleting networks via Settings.app may not work due to modified configuration files. In this case, use iCleaner Pro from Cydia.

Bulk Wi-Fi Network Deletion: Hidden Features

If the list of saved networks has grown to hundreds of entries (for example, after frequently changing locations), deleting them one by one is impractical. Here are some methods for bulk deletion:

• 📱 Android (without root):
  • Use apps like WiFi Manager (requires permission to access settings).
  • In some firmware (for example, ColorOS) there is a built-in "Clear history" option.
• 🍎 iPhone/iPad:
  • Reset network settings: Settings → General → Transfer or reset → Reset → Reset network settings.
  • This will remove All Saved networks, passwords, VPN, and cellular settings!
• 🖥️ Android (with root):
  • Delete the file /data/misc/wifi/WifiConfigStore.xml through Root Explorer.
  • Or run the command: su -c rm /data/misc/wifi/WifiConfigStore.xml.

On Android with root access you can also use SQLite Editor to clear the database settings.db, where networks are stored. However, this is risky—an error can reset all network settings.
