If your iPhone 15 or iPhone 15 Pro freezes, won’t respond to touch, is stuck on a black screen, or becomes completely unresponsive, performing a force restart is one of the fastest and safest ways to fix the issue. Unlike a normal restart, a force restart doesn’t require touchscreen input—so it’s perfect when the screen is frozen or your iPhone won’t react to button presses or swipes.
This guide provides a step-by-step explanation on how to force restart your iPhone 15 or 15 Pro, when to use this method, what it actually does, and what to try next if your iPhone still doesn’t respond.
🔄 What Is a Force Restart?
A force restart (or hard reset) uses a specific sequence of button presses to forcibly reboot the iPhone. This bypasses the standard iOS shutdown procedure, making it ideal for frozen screens or unresponsive apps.
Key Benefits:
- Does not erase any data
- Requires no touchscreen input
- Works even if the phone is completely frozen
✅ A force restart is a safe and effective first step for resolving temporary iOS or app-related issues.
📲 How to Force Restart iPhone 15 and iPhone 15 Pro
🔧 Step-by-Step Instructions:
- Quickly press and release the Volume Up button
- Quickly press and release the Volume Down button
- Press and hold the Side button (on the right side of the device)
- Continue holding the Side button—ignore the screen going black
- When the Apple logo appears, release the Side button
💡 You must press the buttons in quick succession—if you delay, the restart may not trigger.
🧠 Why This Button Sequence Works
The iPhone 15 and 15 Pro no longer have a Home button, so Apple uses this three-step process to reboot Face ID-equipped models. This is the same sequence used on iPhones from the iPhone X through the iPhone 15 Pro Max.
🛠 When Should You Force Restart Your iPhone 15?
A force restart is recommended if your iPhone 15 or 15 Pro is:
- Completely frozen or unresponsive
- Stuck on a black screen but powered on
- Lagging heavily, and standard shutdown isn’t working
- Trapped in a boot loop or on the Apple logo screen
- Not responding to touchscreen taps, swipes, or buttons
🔋 If your screen is black and the phone won’t turn on, first plug it into a charger for 30 minutes—then try a force restart.
❌ What a Force Restart Does Not Do
Understanding what a force restart doesn’t do can help you avoid confusion:
| Does Not… | Explanation |
| Erase any personal data | Safe for photos, apps, and settings |
| Reset your phone to factory state | Only reboots the device |
| Fix serious software corruption | May require a restore if the OS is damaged |
| Remove screen locks or passcodes | Not a bypass for security features |
🧠 Think of it as a “power cycle” for your phone, not a full reset.
🔌 What If the Force Restart Doesn’t Work?
If your iPhone 15 remains unresponsive even after a force restart attempt:
Charge the Phone
- Plug into a certified USB-C charger for at least 30–60 minutes
- If no charging symbol appears, try a different cable or power adapter
- Then retry the force restart steps
Check for Physical Button Issues
- Ensure none of the volume or side buttons are jammed or damaged
- Try pressing buttons firmly and swiftly
Try Recovery Mode via a Computer
If your iPhone is stuck on a black screen, boot loop, or Apple logo:
How to Enter Recovery Mode:
- Connect iPhone to a Mac or PC using a USB-C cable
- Follow the same force restart button sequence, but continue holding the Side button even after the Apple logo appears
- Release the button when the Recovery Mode screen appears (a computer and cable icon)
- On your computer, choose Update (to reinstall iOS without erasing data)
- If Update fails, try Restore (this erases the device)
⚠️ Restore will delete all data—use only if Update doesn’t work and you have a backup.
🆘 When to Contact Apple Support
If your iPhone 15 or 15 Pro:
- Won’t respond even after charging and a force restart
- Is stuck in a continuous restart loop
- Has a screen that won’t turn on even when plugged in
- Shows signs of physical or liquid damage
…then it’s time to contacthttps://support.apple.com/ or visit an Apple Store or Authorized Service Provider for diagnostics.
