iPhone Keeps Restarting? Here Are 12 Proven Fixes That Actually Work

Let’s go through the most effective methods step by step.

1. Force Restart Your iPhone

If your iPhone keeps restarting in a loop, performing a force restart can often break the cycle and refresh the system.

How to Force Restart:

• iPhone 8 and later: Quickly press and release Volume Up, then Volume Down, then press and hold the Side button until you see the Apple logo.
• iPhone 7 / 7 Plus: Press and hold Volume Down + Power button together.
• iPhone 6s and earlier: Press and hold Home + Power button together.

This method doesn’t delete your data and can instantly fix minor software glitches.

2. Update iOS to the Latest Version

If your iPhone keeps restarting, outdated or buggy iOS versions may be the culprit. Apple regularly releases updates to fix bugs, improve performance, and enhance stability.

Steps:

1. Go to Settings → General → Software Update
2. Download and install the latest version of iOS

Updating your iPhone can eliminate software conflicts that cause random restarts.

3. Check iPhone Storage

Low storage can severely affect your iPhone’s performance and cause continuous restarts.

How to Check:

• Go to Settings → General → iPhone Storage

If your storage is almost full:

• Delete unused apps
• Clear old photos and videos
• Remove unnecessary files

Maintaining at least 5–10 GB of free space can help your iPhone run smoothly.

4. Update or Delete Problematic Apps

Sometimes, a single corrupted or poorly optimized app can make your iPhone unstable.

If your iPhone keeps restarting after installing a new app, try:

• Updating all apps from the App Store
• Removing suspicious or recently installed apps

To update apps:

• Open App Store → Profile icon → Update All

5. Reset All Settings

Incorrect settings or corrupted configurations can trigger restart loops. Resetting all settings can fix these issues without deleting your data.

Steps:

1. Go to Settings → General → Transfer or Reset iPhone
2. Tap Reset → Reset All Settings

This will reset Wi-Fi, Bluetooth, and system preferences but keep your data intact.

6. Check Battery Health

A degraded or faulty battery is one of the top reasons why an iPhone keeps restarting.

To check battery health:

• Go to Settings → Battery → Battery Health & Charging

If your battery health is below 80% or shows a service warning, your battery may need replacement.

A failing battery can’t supply stable power, leading to sudden shutdowns and restarts.

7. Avoid Overheating

Excessive heat can cause your iPhone to restart automatically to protect its internal components.

Common causes of overheating:

• Gaming for long hours
• Using heavy apps continuously
• Charging while using
• Exposure to direct sunlight

Fix:

• Remove the case while charging
• Let your phone cool down
• Avoid intense usage for extended periods

8. Restore iPhone Using iTunes or Finder

If none of the basic fixes work, restoring your iPhone can eliminate deep software issues.

Steps:

1. Connect your iPhone to a computer
2. Open iTunes (Windows) or Finder (Mac)
3. Select your device
4. Click Restore iPhone

⚠️ Backup your data before restoring, as this will erase everything.

9. Check for Water or Physical Damage

If your iPhone keeps restarting after a drop or water exposure, internal hardware components may be damaged.

Signs of hardware damage include:

• Random reboots
• No charging
• Overheating
• Touch issues

In such cases, professional repair is highly recommended.

10. Inspect Charging Cable and Adapter

Faulty charging accessories can cause power fluctuations, leading to restarts.

Use original or certified cables and adapters. Try changing your charger to see if the issue stops.

11. Factory Reset as a Last Software Solution

If nothing works, performing a factory reset may help.

Steps:

1. Backup your iPhone
2. Go to Settings → General → Transfer or Reset iPhone
3. Tap Erase All Content and Settings

If your iPhone still keeps restarting after a factory reset, the problem is almost certainly hardware-related.
