Is your iPhone refusing to update? You’re not alone. Many iPhone users face this challenge. A mix of common issues like lack of space, poor internet connection, or phone compatibility often cause these update troubles.
To start, check your internet connection. Updates need a strong connection to download. Also, explore your iPhone’s storage. Updates need space. Go to Settings > General > iPhone Storage. Delete old apps or large files if needed.
Your iPhone model might also be too old for the new update. Some updates need newer models. If nothing works, you might need to use a computer. Connect your iPhone and check for updates through iTunes or Finder.
My iPhone Won’t Update: Troubleshooting Guide
Keeping your iPhone updated ensures you get the latest security patches, features, and performance improvements. But sometimes, your iPhone might refuse to update — showing errors, freezing during installation, or failing to download the update altogether.
If you’re stuck wondering “Why won’t my iPhone update?”, this step-by-step troubleshooting guide will help you fix it quickly.
🧩 Common Reasons Why an iPhone Won’t Update
Before diving into fixes, it helps to understand what might be causing the issue. Common reasons include:
- Not enough storage space
- Poor Wi-Fi or internet connection
- Low battery or power issues
- Apple’s update servers are busy or down
- Software glitches or corrupted downloads
- Outdated or incompatible iOS version
- Using an old or unsupported device
🧭 Step 1: Check for Compatibility
Each iOS version supports only certain iPhone models.
Before updating, visit Apple’s official iOS compatibility list to confirm your iPhone supports the latest version.
💡 Tip: If your iPhone is more than 5–6 years old (like iPhone 6 or earlier), it may no longer receive iOS updates.
📶 Step 2: Check Your Internet Connection
A stable Wi-Fi connection is required for iOS updates.
- Go to Settings → Wi-Fi and make sure you’re connected to a reliable network.
- Avoid public Wi-Fi networks.
- If your connection is slow, restart your router or switch to another network.
⚠️ You can’t download iOS updates over cellular data unless you’re using a 5G-capable iPhone with “Allow More Data on 5G” enabled.
💾 Step 3: Free Up Storage Space
If your iPhone doesn’t have enough free space, the update won’t install.
- Go to Settings → General → iPhone Storage.
- Delete unused apps, photos, or videos.
- You’ll typically need at least 6–8 GB of free space for major updates.
💡 Try offloading apps instead of deleting them — this saves storage while keeping your data intact.
🔋 Step 4: Check Battery and Power Source
Your iPhone needs at least 50% battery to install updates.
- Plug your iPhone into a charger.
- Keep it connected during the entire update process to avoid interruptions.
🔄 Step 5: Restart Your iPhone
A simple restart can often fix temporary software glitches.
To restart:
- For iPhones with Face ID: Press and hold Side button + Volume button, then slide to power off.
- For iPhones with Home button: Hold the Side (or Top) button, then slide to power off.
After 10 seconds, press the Side button again to turn it back on.
⚙️ Step 6: Try Updating Again
Once your phone restarts, try again:
- Go to Settings → General → Software Update.
- Tap Download and Install.
- Follow the on-screen instructions.
If you still see an error or the update fails to verify, continue to the next steps.
💻 Step 7: Update Using a Computer (Finder or iTunes)
If your iPhone won’t update over Wi-Fi, try updating via a computer.
On a Mac (macOS Catalina or later):
- Connect your iPhone using a USB cable.
- Open Finder.
- Select your iPhone in the sidebar.
- Click Check for Update, then Download and Update.
On Windows PC or older macOS:
- Open iTunes (make sure it’s the latest version).
- Connect your iPhone.
- Click the Device icon → Summary → Check for Update.
- Click Download and Update.
🧠 Tip: If the download takes more than 15 minutes, your iPhone might exit the update screen. Just repeat the process.
🧰 Step 8: Use Recovery Mode (If Update Fails Repeatedly)
If your iPhone still won’t update, use Recovery Mode to reinstall iOS.
This will not erase your data unless you choose “Restore.”
Steps:
- Connect your iPhone to a computer.
- Force restart your iPhone:
- iPhone 8 or later: Press and quickly release Volume Up, then Volume Down, then hold the Side button until you see the Recovery Mode screen.
- iPhone 7/7 Plus: Hold Volume Down + Side button.
- iPhone 6s or earlier: Hold Home + Top (or Side) button.
- When Finder or iTunes detects your device, click Update.

🧼 Step 9: Delete and Redownload the Update File
Sometimes, the downloaded update file gets corrupted.
- Go to Settings → General → iPhone Storage.
- Find the iOS update file (e.g., “iOS 18.1”).
- Tap it → Delete Update.
- Go back to Settings → General → Software Update and download it again.
☁️ Step 10: Check Apple’s System Status
If everything seems fine but the update still fails, Apple’s servers might be down.
- Visit Apple’s System Status page.
- Check if “iOS Software Update” is showing an outage or maintenance.
If it’s down, wait a few hours and try again.
🧠 Bonus: Reset Network Settings
If you’re still having Wi-Fi or connection issues:
- Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
- Reconnect to your Wi-Fi and try updating again.
⚠️ This will erase saved Wi-Fi passwords and VPN settings, so note them down first.

Troubleshooting iPhone Update Issues
When your iPhone won’t update, it can be for several reasons. This guide will help you tackle these problems step by step, ensuring that your device gets the latest software updates smoothly.
Verifying Compatibility and Storage
First, check if your iPhone is compatible with the iOS version you’re trying to install. Go to the Settings app, tap on General, then Software Update to see the latest available version for your device. Also, ensure there is enough free space by navigating to Settings > General > iPhone Storage. If necessary, delete some files or apps to free up space.
Checking Network and Software Requirements
A reliable network connection is essential for an iPhone update. Connect your device to a strong Wi-Fi network. Avoid using cellular data for updates. Also, check Apple’s servers for any outages. Make sure your device has enough battery or is plugged in. Additionally, disabling VPN or security software might help.
Interpreting Error Messages
Error messages can provide clues about why an update fails. If you see “Unable to Check for Update,” ensure your Internet connection is stable. For “Storage Not Enough” errors, free up space as mentioned earlier. If you get an “Update Failed” message, restart your iPhone and try again. Persistent errors may need more advanced solutions.
Utilizing iTunes and Finder for Updates
If over-the-air updates don’t work, use iTunes or Finder on your computer. Connect your iPhone via USB cable. Open iTunes (Windows) or Finder (Mac), select your device, and choose Check for Update. This method can bypass some issues that prevent direct updating from the iPhone itself.
Executing Recovery Mode and DFU Restore
If all else fails, placing your iPhone in recovery mode or performing a DFU (Device Firmware Update) restore can resolve stubborn update issues. For recovery mode, connect your iPhone to a computer and press the Volume Up, Volume Down, and hold the Side Button until the Apple logo appears. Follow prompts in iTunes or Finder. DFU restore is more advanced and should be used as a last resort.
Addressing Specific Device Scenarios
Different iPhone models may need specific troubleshooting steps. For example, iPhone 11 and newer have different button combinations for forcing restart. Older models with a Home Button may need different steps. Always consult the device-specific guide if usual methods don’t work. Follow Apple’s support advice to ensure you cover all possible scenarios.
