How to disable automatic iPhone updates via Wi-Fi: all the methods

Method 1: Disable automatic updates in iOS settings

The most obvious method is to use built-in options iOSHowever, there are some pitfalls here: Apple regularly changes the location of settings, and some parameters may be reset.

Instructions for iOS 15–18:

1. Open Settings → General → Software Update.
2. Tap on Automatic update.
3. Turn off both switches:
   • 🔄 Download iOS updates
   • 📱 Install iOS updates

But this is not enough! Apple leaves a loophole: even with the settings disabled, the system can download updates if:

• 🔌 iPhone connected to charging and Wi-Fi at the same time.
• 🌙 Time on device - from 2:00 to 4:00 am (optimized charging mode).
• 📶 The network is marked as "trusted" (for example, a home router).

To permanently block background downloads, go to Settings → Wi-Fi, tap the "i" icon next to your network and Disable the "Automatic download of updates" option (available from iOS 17.2).

Method 2: Limit background activity using Screen Time

If the default settings don't help, you can take a workaround by restricting access to update servers. Apple via function Screen timeThis method works even on iPhone With managed via MDM (corporate devices).

Step-by-step instructions:

1. Open Settings → Screen Time → Content & Privacy Restrictions.
2. Enable restrictions if they are disabled (create a password and remember him!).
3. Go to Restrictions → Installing Apps and select Do not allow.
4. Go back and tap System applications, then turn it off Software update.
5. To be on the safe side, block access to App Store (chapter iTunes and App Store).

This method does not cancel the download of updates, but blocks their installation. The firmware files will be downloaded in the background and take up memory space (check in Settings → General → iPhone Storage), but not installed.

⚠️ Attention: If you forget your password Screen time, it can only be restored by resetting iPhone to factory settings. Apple does not provide official ways to bypass this limitation.

For complete control, add domains to the blacklist Apple, related to updates:

mesu.apple.com
applsus.apple.com
swscan.apple.com

This can be done through Settings → Screen Time → Content Restrictions → Web Content → Restricted SitesEnter domains manually and save.

Method 3: Blocking updates at the router level

If iPhone updated through your home Wi-Fi, you can block access to servers Apple on the router. This is the most reliable method, as it doesn't depend on settings. iOS.

Instructions for popular router models:

To block by MAC address:

1. Find your MAC address iPhone V Settings → General → About.
2. In the router control panel, create a rule that prohibits this MAC address from accessing domains. Apple.
3. Save the settings and reboot the router.

⚠️ Warning: IP range blocking 17.0.0.0/8 may disrupt the operation of other services Apple (iCloud, Apple Music, FaceTime). If you need these features, use domain-specific blocking.

An alternative option is - limit internet speed For iPhone through QoS (Quality of Service). Set a rule so that the device receives no more than 100 KB/s—this isn't enough to download updates (1–5 GB in size), but it's sufficient for messaging apps and email.

Method 4: Using a VPN or alternative DNS

If blocking on the router is not possible (for example, you are connected to public Wi-Fi), you can redirect update traffic to "nowhere" using VPN or custom DNS.

Method 1: VPN with traffic filtering

Install a VPN application that supports routing rules, such as:

• 🛡️ AdGuard Pro (there is a free version with limitations).
• 🌍 1.1.1.1: Faster Internet (from Cloudflare).
• 🔒 NextDNS (allows you to create domain blacklists).

Setting up in AdGuard Pro:

1. Open the app and go to Settings → Filtering → Custom Rules.
2. Add the following lines:

   ||mesu.apple.com^$important
   ||swscan.apple.com^$important
   ||applsus.apple.com^$important

3. Enable VPN mode in settings iOS (Settings → VPN).

Method 2: Change DNS on your router or device

Use DNS servers that block domains Apple:

• 🔴 AdGuard DNS: 176.103.130.130 And 176.103.130.131 (filters updates).
• 🟢 NextDNS: create an account, add domains Apple blacklist and use generated DNS.
• 🔵 ControlD: a paid service with flexible blocking settings.

To change DNS to iPhone:

1. Go to Settings → Wi-Fi.
2. Tap the "i" icon next to your network.
3. In the section DNS select Manually and add addresses (eg 176.103.130.130).

Method 5: Radical measures (for advanced users)

If none of the above methods worked, there are still extreme measuresThey are suitable for users willing to sacrifice some functionality for complete control over the device.

Option 1: Disabling Apple services via the host file (requires jailbreak)

For jailbroken devices:

1. Install Filza File Manager or iFile through Cydia/Sileo.
2. Follow the path /etc/hosts.
3. Add the following lines:

   127.0.0.1 mesu.apple.com
   127.0.0.1 swscan.apple.com
   127.0.0.1 applsus.apple.com

4. Save the file and reboot iPhone.

Option 2: Manually remove the update file

If the update has already been downloaded but not installed, you can uninstall it:

1. Go to Settings → General → iPhone Storage.
2. Find the downloaded update in the list (usually 1-5 GB).
3. Tap on it and select Uninstall update.

Option 3: Using a configuration profile (for iOS 15–17)

Download and install a special profile that blocks updates (for example, from the website iOS God or Jailbreak Repo). These profiles modify system settings, but can disrupt iCloud or cause certificate errors.

⚠️ Warning: Radical methods may disrupt the stability of iOS, cause iCloud sync errors, or even block access to the App Store. Use these only if other methods have failed and you are prepared for the possible consequences.
