However, if your goal is to maintain the current stable version operating system Or save data, the instructions below will be extremely helpful. We'll cover both built-in tools and workarounds for complete control of your device.
Basic automatic update settings in iOS
The first step to gaining control over your system is to check your default settings. Apple allows users to control how and when their device receives firmware files. These options are often enabled by default for maximum security, but they can easily be changed manually through the settings menu.
First, you need to go to the main system configuration section. Find and select the item Settings, then scroll down to the tab MainThis is where the key switches responsible for background operating system activity, including downloading installation packages, are located.

Settingson the main screen. - ⚙️ Go to the section
Main, then selectSoftware update. - 🔄 Click on the item
Auto-update. - 🚫 Flip the switch Downloading iOS updates to the inactive position.
⚠️ Attention: Even after disabling auto-download, a notification about a new version may still appear in the settings. This is normal, as the Apple server notifies the device of the update, but the file itself will not be downloaded.
After completing these steps, your smartphone The system will stop downloading update files automatically via Wi-Fi. However, it's worth noting that when connected to a charger and with a stable connection, the system may occasionally prompt you to install the update if you initiate the check yourself. Disabling the download doesn't completely prevent installation if the user manually clicks the "Download and Install" button.
Using restrictions to prevent updates
A more radical and reliable method is to use the Screen Time feature (known as Restrictions in older versions of iOS). This approach allows you to prohibit changes to software update settings at the system level, effectively blocking the ability to install a new version. iOS without entering a special code.
This method is especially effective for corporate devices or children's phones, where it's necessary to lock down the current software version. It works by creating a restriction profile that hides or blocks access to system update functions.
To activate this mode, go to Settings and select a section Screen timeIf you're using your device for the first time, you'll need to tap "Turn on Screen Time" and select "This is My iPhone." Next, you'll need to set a passcode, which will be required to change any restrictions.

- 📲 Find the section
Changes(or "Allow changes"). - 🚫 Set a ban for the item Software update.
After applying these settings, the update section in the main settings may become uneditable, or the install button may be disabled. This creates a secure barrier to prevent accidental or automatic installation of the new version. operating systemThe restriction can only be removed by knowing the previously set password.
⚠️ Attention: Don't forget your Restrictions password. Restoring access to settings without knowing the code is only possible by resetting your device, which will result in the loss of all data.
☑️ Setting up restrictions
Deleting the downloaded update file
It often happens that iPhone The update file has already downloaded in the background, and it's taking up several gigabytes of storage. Even if you've disabled automatic downloads, this file remains on your device and may trigger the installation at the first opportunity. It must be removed manually.
Update files are stored in a special storage section accessible through Settings. Deleting this file frees up space and removes the update icon from the Settings icon, although the server will still see your device as requiring an update.
To perform cleaning, follow the path Settings → Main → iPhone storage (in some versions Using storage). In the list of apps, find a file with a name like "iOS 17.x" or something similar. Tapping it will reveal the option to delete it.
Settings → General → iPhone Storage → [iOS File] → Delete UpdateAfter confirming the action, the file will be erased from the device's memory. Now, even if you accidentally connect to Wi-Fi, the phone will have nothing to install, as the installation package has been deleted. This is an effective way to temporarily solve the problem of low storage space and remove the annoying reminder.
Why does the file reappear?
The file may be downloaded again unless you completely disable updates through restrictions or if the system considers the update to be critical for security, but this rarely happens with automatic updates disabled.
Blocking via DNS settings (for advanced users)
For those seeking maximum control, there's a method for blocking Apple update servers at the network request level. By changing the DNS settings in your Wi-Fi settings, you can redirect your device's update server requests to nowhere or to a local address. This prevents a connection from being established with the server. mesu.apple.com.
This method requires manual configuration for each Wi-Fi network you connect to. It's not 100% guaranteed, as Apple uses multiple domain names and IP addresses, which can change. However, in most cases, it effectively stops the update check.
| Parameter | Meaning / Action | Note |
|---|---|---|
| Server domain | mesu.apple.com | Primary update server |
| Server domain | gdmf.apple.com | Mobile Device Management Server |
| Blocking method | DNS Filter / Hosts | A router or app is required. |
| Result | Verification error | The phone will report that there is no network during the update. |
This can be done through your router settings if it supports domain filtering, or by using special configuration profiles and DNS management apps on your iPhone (such as AdGuard or similar apps with tracker blocking functionality). By blacklisting update domains, you'll make verification impossible.
Keep in mind that blocking system domains may impact other Apple services, such as device activation or some built-in apps. Only use this method if you understand the risks and know how to quickly reset your DNS settings back to automatic.
The impact of Do Not Disturb and Background Mode
There's a common misconception that power saving or Do Not Disturb modes completely stop background update downloads. In fact, iOS Designed to prioritize loading system files when the device is connected to Wi-Fi and charging, regardless of notification status.
Low Power Mode can indeed slow down background activity, but it doesn't guarantee a complete stop of update downloads if they've already been flagged as critical by the system. Therefore, relying solely on the yellow battery icon isn't recommended.
The best strategy is a combination of methods: disabling auto-updates in the settings and deleting the downloaded file. If you want to ensure that the installation process doesn't start overnight while the phone is charging, make sure the toggle in the section is Auto-update turned off.
It's also worth remembering about the background download feature. If you interrupt an update installation, the system may attempt to resume it at the first available opportunity. Regularly checking your storage will help you stay on top of things and avoid any surprises.
