iPhone X Keeps Crashing and Freezing? Here’s How to Fix It

If your iPhone X has started crashing, freezing, or running sluggishly, it’s likely a sign of system instability. These symptoms often appear after an iOS update or when a misbehaving app gets out of control. The good news? There are several reliable ways to troubleshoot and fix it.

Try the following solutions in order until your iPhone X is stable and snappy again.

1. Soft Reset (Restart Your iPhone X)

A quick restart clears minor bugs and memory glitches:

Press and hold the Side button + Volume Up (or Down) until the power slider appears.
Slide to power off.
Wait 30 seconds, then press and hold the Side button again until you see the Apple logo.

This won’t erase your data.

2. Check for an iOS Update

Apple regularly pushes updates to fix bugs and performance issues.

Go to Settings > General > Software Update.
If an update is available, tap Download and Install.

Always back up your data before updating, just in case.

3. Update All Apps

Outdated apps can crash and cause system slowdowns—especially after a major iOS update.

Open the App Store.
Tap your profile icon, scroll down, and tap Update All.

Once updates are installed, restart your iPhone.

4. Delete Problematic Apps

If your iPhone freezes while using a certain app, that app might be the culprit.

Tap and hold the app until it jiggles.
Tap the X, then confirm deletion.
Reinstall the app later from the App Store if needed.

You can also check for crash reports in Settings > Privacy & Security > Analytics & Improvements > Analytics Data to spot faulty apps.

5. Free Up Storage

Low storage can cause crashes, freezes, and sluggish performance.

Go to Settings > General > iPhone Storage.
Delete unused apps, old messages, photos, or large video files.
Offload apps you don’t use often to save space while keeping your data.

Aim to leave at least 2–5 GB of free space on your iPhone.

6. Reset All Settings

A clean slate for system settings can fix hidden software conflicts.

Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
This resets Wi-Fi, Bluetooth, notifications, and more—but won’t delete your data.

After the reset, reconfigure your preferences and test for stability.

7. Factory Reset (Erase All Content and Settings)

Still crashing? A full reset may be needed to fix deep software issues.

⚠️ Back up your data before doing this.

Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
Follow the on-screen prompts to reset and start fresh.

Set up the iPhone as new, test it, and only restore from a backup if the issue is gone.

8. Restore with iTunes (Recovery or DFU Mode)

If the issue continues, restoring via computer may help:

Use Recovery Mode Restore or DFU Mode Restore via Finder or iTunes.
These methods reinstall iOS and remove corrupted files or configurations.

Full instructions can be found on our [iPhone X Tutorials page].

9. Still Not Fixed? Visit Apple Support

If none of the above steps help, the issue could be hardware-related (like a failing NAND chip or logic board component). Visit an Apple Store or Apple Support to schedule diagnostics. If you’re still under warranty or have AppleCare, you may be eligible for a replacement.
