How to fix iphone keeps restarting every a few minutes after update

My iPhone 15 keeps restarting as well after replacing the screen.

Using DFU (Device Firmware Update) mode is one of the most effective and completely free methods to fix iPhone boot loop issues, especially when your iPhone keeps restarting every few minutes after an update.

Think of DFU mode as the "nuclear option" for solving iOS problems. Unlike the standard Recovery Mode you might be familiar with, DFU mode works at a much deeper, hardware level . When you fix iPhone boot loop using DFU mode, you are essentially bypassing the current, corrupted operating system entirely and reinstalling a fresh, clean version directly onto the device's firmware . This makes it incredibly powerful for resolving the most stubborn issues, including the continuous restarting you're experiencing.

How to enter DFU mode (iPhone 8 and later):

1. Connect your iPhone to your computer

2. Quickly press and release Volume Up

3. Quickly press and release Volume Down

4. Press and hold the Side button for 5 seconds

5. Without releasing the Side button, also press and hold the Volume Down button for 5 more seconds

6. Release the Side button but continue holding Volume Down for another 10 seconds

This is the best-kept secret for fixing boot loop issues. If your iPhone keeps restarting every a few minutes, Apple Configurator is a free app from Apple designed for businesses and schools to manage multiple iDevices, but it has a powerful "Revive" feature that iTunes/Finder does not have.

Why this is better than iTunes/Finder:

   The "Revive" function attempts to fix the iOS system without erasing your data

   It can recover devices that iTunes/Finder won't even recognize

   It's completely free and official from Apple

What you do if iPhone keeps restarting every a few minutes:

1. Download Apple Configurator from the Mac App Store (Mac only—this does not work on Windows)

2. Install and open the app

3. Connect your iPhone to your Mac via USB

4. If your device appears, select it

5. Click Actions → Advanced → Revive Device

6. Follow the on-screen prompts

To fix iPhone boot loop, the most reliable free solution is to use a computer. This will reinstall the iOS software and fix any corrupted system files that are causing the restart loop.

How to fix iPhone boot loop:

1. Connect your iPhone to your computer using a USB cable.

2. Open Finder (on Mac) or iTunes (on PC).

3. Put your iPhone into "Recovery Mode." While it's connected to the computer, do the Force Restart button sequence for your model again, but this time, don't let go of the last button. Keep holding it until you see a screen with a picture of a computer and a cable.

4. A Window will pop up on your computer saying there's a problem and giving you two options: Update or Restore.

• First, try "Update." This will attempt to reinstall iOS without erasing your data. This is the best-case scenario.
• If "Update" fails or your phone keeps restarting, you will need to try "Restore." This will erase your iPhone and install a fresh, clean copy of the latest iOS. After it's done, you can set up your phone and restore your data from a backup.

Important Warning: The final step of this process will erase everything on your iPhone. However, you will have the option to restore all your data from a backup afterwards. If you have a recent iCloud or computer backup, you won't lose anything.

iPhone keeps restarting every a few minutes? If the force restart didn't work, let's rule out a few simple, common causes.

• Check Your Battery: A battery that is too low or failing can cause restarts.
• Plug it in: Connect your iPhone to a charger and let it charge for at least 30 minutes to an hour. Sometimes a nearly dead battery can cause this behavior.
• Check Battery Health: If you can get your phone to stay on long enough, go to Settings > Battery > Battery Health & Charging. If the "Maximum Capacity" is below 80% or it says "Service Recommended," the battery itself might be the problem.
• Free Up Storage Space: If your iPhone's storage is completely full, it can cause major problems. If you can briefly access your phone, go to Settings > General > iPhone Storage. If it's full or nearly full, try deleting some old videos, photos, or large apps you don't use.

If you have tried all of the above (especially the "Restore" option with a computer) and your iPhone keeps restarting every a few minutes, it unfortunately points to a hardware problem. The most likely culprits are a failing battery or another internal issue.

At this point, your best and safest option is to contact Apple Support or visit an Apple Store or an Apple Authorized Service Provider. They can run proper diagnostics to find the exact hardware problem and fix it for you. Given that you've already tried the free software fixes, this is the next logical step.

Reset All Settings is a built-in iOS troubleshooting option that can help fix iphone keeps restarting, and it will not erase your personal data like photos, apps, or messages.

It resets all system preferences to default, which can fix conflicting settings that cause frequent restarts, but it requires reconfiguring your custom settings afterward.

First, make sure you remember your Wi-Fi passwords and other important settings. Go to Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings.

Enter your passcode when prompted, then confirm the reset. Wait for your iPhone to restart and complete the process.

Once the reset is done, you can rejoin your Wi-Fi networks and re-adjust your system preferences.

This method cannot fix hardware-related issues that cause restarts, so it is only suitable for users experiencing software-related problems.

If you are unsure about resetting your settings, you should back up your iPhone first. This is a safe operation for personal data, and it can effectively fix iphone keeps restarting caused by system configuration errors, but you should think it through carefully.

Removing problematic apps is an effective way to fix iphone keeps restarting, as incompatible or buggy third-party apps are a common cause of frequent system reboots, especially if the issue started right after installing or updating a specific app.

Step 1: Open Settings on your iPhone, then go to General > iPhone Storage

Step 2: Look for apps that were installed or updated shortly before or after the device started restarting frequently

Step 3: Tap the problematic app, then select Delete App to remove it completely from your device

Finally, use your iPhone normally for a while to see if the frequent restarts have stopped

Common culprits include social media apps, VPN apps, third-party keyboard apps, and background tools. Removing these unstable apps can effectively fix iphone keeps restarting.

Drawback: Deleting apps will remove their local data and settings, and you may lose saved login information, offline files, or personal data if you have not backed them up.

Checking storage space can help fix iphone keeps restarting, since low storage often causes constant restarts.

How to fix iphone keeps restarting

1. Go to Settings > General > iPhone Storage
2. Check if the available space is less than 1 GB
3. Delete apps you no longer use
4. Back up your photos to iCloud or your computer

Notes

• Back up important data before deleting apps or clearing cache to avoid accidental data loss.
• After freeing up space, restart your iPhone to check if the restart issue is fully resolved.

Freeing up storage space helps iOS run smoothly and, by providing the system with sufficient space to operate stably, effectively resolves the issue of frequent iPhone reboots.
