How to Fix iPhone 17 Keeps Restarting Randomly Issue in 2025

Part 1. Why Does My iPhone 17 Keep Restarting?

If your iPhone 17 keeps restarting on its own, it could be because of the following reasons:

• Update Problems: Sometimes new iOS updates have bugs that make your iPhone unstable, especially if problems started after an update.
• App Issues: Old, faulty, or incompatible apps can also crash your phone, especially if they use too many resources.
• Corruption: In some cases, corrupted system files can trigger restarts.
• Battery Damage: A worn-out or damaged battery can cause power issues and force restarts.
• Overheating: Heavy use or charging problems can overheat the phone, so it keeps restarting.
• Physical damage: Water exposure or drops can harm internal parts, including the charging port.
• Insufficient Storage: If your storage is almost full, the phone may struggle to run smoothly and restart.
• Loose or Faulty SIM card: This can also cause performance issues.

Part 2. Quick Checks Before Troubleshooting iPhone 17 Keep Restarting

When your iPhone 17 is restarting randomly, it’s wise to perform some basic checks first to rule out the reasons for this issue. Here they are:

Is Your iPhone Overheating?

Overheating can make an iPhone 17 restart to protect its parts. It often happens during heavy use like gaming, recording videos, or being in direct sunlight. To check, touch the back of the phone. If it feels very hot or you see a heat warning, it’s overheating. To fix it, close demanding apps, move to a cooler place, take off the case, and avoid charging until it cools down.

Did the Issue Start After a New App or Update?

New apps or recent updates, whether to apps or iOS, can sometimes cause bugs or compatibility problems that make your iPhone 17 restart. If the issue began after installing something new, try deleting that app. But if it started after an update, see if other users have the same problem and check for updates that might fix it.

Is There Enough Free Storage Space?

If your iPhone 17’s storage is almost full, it can slow down or restart because iOS needs free space to work properly. To check:

• Head to “Settings.” Then, choose “General.” Tap “iPhone Storage.”

Free up space by deleting unused apps, removing old photos and videos (or moving them to the cloud/computer), and clearing browser data. Also, offload apps you don’t often use.

Check Battery Health

If your iPhone 17 keeps randomly restarting, it could be because of a worn-out battery, as it can’t supply enough power. To check battery health:

• Head to “Settings.” Then, choose “Battery.”
• Tap “Battery Health & Charging.” If the maximum capacity is below 80%, it’s likely time to replace the battery through Apple or an authorized repair service.

Part 3. Top 9 Ways to Fix iPhone 17 Keeps Restarting

When your iPhone 17 keeps crashing and restarting, and the basic checks don’t cut it, here’s how to troubleshoot this issue with 9 solutions:

Solution 1: Force Restart iPhone 17

If your iPhone 17 keeps restarting itself, it could be because of a background app consuming resources or a minor iOS glitch. You can fix these issues by force restarting your phone:

• Press and hold the “Volume Up” button on your iPhone 17. Then, release it quickly. Do the same with the “Volume Down” button.
• Press and hold the “Side” button and keep it pressed until you see the Apple logo.

Solution 2: Delete Recently Installed or Problematic Apps

Some apps might crash or freeze, or consume a disproportionate amount of battery, especially the recently installed ones. This can lead to a restart loop on your iPhone 17. However, you can remove these apps to fix the problem. To do so:

• Open “Settings” on your iPhone 17. Then, choose “General.” Tap “iPhone Storage.”
• Choose the app you want to remove. Click “Delete App.” Hit “Delete App” to confirm.

Solution 3: Put the iPhone into Recovery Mode

• Press and quickly release “Volume Up.” Then, do the same with the “Volume Down.”
• Press and hold the “Side” button (don’t let go when the Apple logo appears). Keep holding until you see the “connect to computer” screen.
• On your computer, the Finder (Mac) or iTunes (Windows) will show options to “Update” or “Restore” your iPhone 17. Tap “Update.”

Solution 4: Free Up Storage Space

In case your iPhone 17 Pro keeps restarting, it could be large apps/attachments/media files or temporary, or cache data hogging much storage space. Thus, you’ll need to free up storage space on your phone to fix the restart loop:

  • Delete unused apps (hold icon > Remove App > Delete App or delete in iPhone Storage settings).
  • Offload unused apps to keep data (Settings > iPhone Storage > app > Offload App).
  • Clear app cache by deleting and reinstalling the app.
  
• Optimize Photos & Videos:
• Lower photo/video quality.
• Turn on iCloud Photos and Optimize iPhone Storage in Settings > Photos.
• Delete unwanted media from Videos or Recently Deleted albums.

• Manage Messages:

• Safari: Settings > Safari > Clear History and Website Data > Clear History.
• Chrome: Menu > Settings > Privacy and security > Clear Browsing Data.
