iPhone 10 Keeps Restarting? Fix It Now

If your iPhone 10 (iPhone X) is stuck in a restart loop—turning on, showing the Apple logo, then shutting down—you’re not alone. This guide walks you through the most effective fixes, from simple force restarts to recovery mode reinstalls, so you can get your phone stable again.

What You’ll Need

A computer (Mac or Windows) with the latest version of iTunes or Finder (macOS Catalina or later).
A USB-to-Lightning cable that is known to work.
Access to Wi-Fi (for software updates or restore).
Your Apple ID password (if you need to restore from a backup).

Step-by-Step

Force restart your iPhone. Press and quickly release the Volume Up button, then press and quickly release the Volume Down button, then press and hold the Side button until you see the Apple logo. Keep holding for about 10 seconds—even if the logo appears, hold a bit longer until the screen goes black and the logo reappears. This often clears a temporary glitch.
Check for physical damage or water exposure. If your phone recently got wet or dropped, the restart loop could be hardware-related. Look at the SIM tray—if the liquid contact indicator inside is red, water damage is likely. In that case, skip to the recovery mode step, but be prepared that a hardware repair may be needed.
Update iOS via recovery mode. Connect your iPhone to your computer, open Finder (macOS Catalina or later) or iTunes (Windows or older macOS). Put your iPhone into recovery mode: press and release Volume Up, press and release Volume Down, then press and hold the Side button until the recovery mode screen appears (a computer icon and a cable). When prompted, choose “Update” (not “Restore”). This reinstalls iOS without erasing your data. If the update fails or takes longer than 15 minutes, your phone will exit recovery mode—repeat the steps if needed.
Restore as a last resort. If updating doesn’t work, put your phone back into recovery mode and choose “Restore.” This erases your device and installs the latest iOS. Make sure you have a recent backup (iCloud or computer) if possible. After the restore, set up your phone as new or from a backup.
Check battery health. After a successful restore, go to Settings > Battery > Battery Health. If the maximum capacity is below 80% or the phone reports “unknown part,” a degraded battery can cause random restarts. Consider a battery replacement at an Apple Store or authorized service provider.
Reset all settings. If the phone is stable but still occasionally restarts, go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This does not delete your personal data, but it resets Wi-Fi passwords, wallpapers, and other system settings. It can fix software conflicts.

Common Mistakes

Holding the Side button too long during force restart. If you hold it for more than 20 seconds, you might trigger an emergency SOS call or put the phone into a different mode. Stick to the sequence and hold for about 10 seconds.
Skipping the “Update” option. Many users immediately hit “Restore” out of panic, losing data. Always try “Update” first—it preserves your files.
Using a damaged cable. A frayed or non-Apple cable can cause connection drops during recovery, leading to failed updates. Use a cable that you know works.
Ignoring water damage. If the phone got wet, trying to charge it or update it can cause short circuits. Turn it off and let it dry completely before any software fix.

Tips

Keep your iPhone updated. Apple regularly releases iOS updates that fix bugs causing restarts. Enable automatic updates in Settings > General > Software Update.
Monitor your storage. If your iPhone is nearly full, it can become unstable. Keep at least 1-2 GB free. Check Settings > General > iPhone Storage.
Back up regularly. Use iCloud or your computer so that if a restore is needed, you don’t lose precious photos and messages.
Use a genuine charger. Third-party chargers can deliver unstable power, causing restarts. Stick to Apple-certified accessories.

Troubleshooting

If the steps above didn’t fix the problem:

Recovery mode loop: If your phone keeps returning to recovery mode after an update, try a different USB port, use a different cable, or restart your computer. Also, ensure your computer’s firewall or security software isn’t blocking the connection.
Update stuck at Apple logo: If the update freezes, force restart your phone and try again. If it still fails, try restoring (which will erase data).
Phone still restarts after restore: This strongly suggests a hardware issue—most commonly the battery or the logic board. Contact Apple Support or visit an Apple Store for diagnostics. If the phone is out of warranty, you may consider a third-party repair shop, but be aware of quality risks.
No computer available: You can try an over-the-air iOS update if your phone is stable enough to go to Settings > General > Software Update. If it’s not stable, you’ll need to find a computer.

Frequently Asked Questions

Q: Will a force restart erase my data?
A: No. A force restart simply powers off and on the hardware—it does not delete any data.

Q: How long does a recovery mode update take?
A: Typically 5-15 minutes, depending on your internet speed and the size of the iOS update. If it takes longer than 30 minutes, the connection may have failed.

Q: Can I fix a restart loop without a computer?
A: Sometimes. If the phone is stable enough, you can try resetting all settings or updating via Wi-Fi. But if it restarts every few minutes, a computer is usually necessary.

Q: Why does my iPhone restart when I open a specific app?
A: That app may be poorly optimized or incompatible with your iOS version. Try updating the app or deleting it. If the problem persists, the app may be causing a system crash.

Q: Is a restart loop always a software problem?
A: No. Hardware issues like a swollen battery, water damage, or a failing logic board can also cause restart loops. If software fixes don’t help, get a hardware diagnostic.

Q: Will restoring my iPhone remove the jailbreak?
A: Yes, a restore will remove any jailbreak and return the phone to stock iOS. If you have a jailbreak, that could be the cause of the restart loop, so restoring is a good fix.
