🔍 Quick Diagnosis: Why Your iPhone Won't Turn On
Before we dive into solutions, it's important to understand the most common causes:
- Battery completely drained - Most common cause
- Faulty charging cable or adapter - Hardware issue
- Software crash or freeze - iOS-related problem
- Hardware damage - Physical damage to components
- Water damage - Liquid exposure
🔌 Fix #1: Check Your Charging Setup
The most common reason an iPhone won't turn on is a completely drained battery. Here's how to properly check your charging setup:
🔍 Inspect the Charging Port
- Look inside your iPhone's charging port with a flashlight
- Check for lint, debris, or corrosion
- Gently clean with a dry toothbrush if needed
- Never use metal objects - you could damage the pins
🔌 Test Your Charging Cable
- Try a different Lightning cable (or USB-C for iPhone 15)
- Use a different wall adapter
- Test the cable with another device if possible
- Look for visible damage on the cable
💡 Pro Tip
If you see a red battery icon or charging symbol, your iPhone is charging but the battery was completely drained. Wait 15-30 minutes before trying to turn it on.
🔄 Fix #2: Force Restart Your iPhone
A force restart (hard reset) can resolve software freezes that prevent your iPhone from turning on. The method varies by iPhone model:
📱 iPhone 8 and Later (Including iPhone 15)
- Quickly press and release the Volume Up button
- Quickly press and release the Volume Down button
- Press and hold the Side button until you see the Apple logo (10-15 seconds)
📱 iPhone 7 and iPhone 7 Plus
- Press and hold both the Volume Down and Side buttons
- Keep holding until you see the Apple logo (10-15 seconds)
📱 iPhone 6s and Earlier
- Press and hold both the Home and Top/Side buttons
- Keep holding until you see the Apple logo (10-15 seconds)
🔄 Fix #3: Try Recovery Mode
If a force restart doesn't work, try putting your iPhone in Recovery Mode and restoring it through iTunes or Finder:
- Connect your iPhone to a computer with iTunes (PC/older Mac) or Finder (Mac with macOS Catalina+)
- Force restart your iPhone but keep holding the buttons when the Apple logo appears
- Keep holding until you see the Recovery Mode screen (cable and computer icon)
- iTunes/Finder will detect your iPhone and offer to restore it
- Choose "Update" first to try fixing without losing data
⚠️ Important
Recovery Mode restoration will erase all data if you don't have a recent backup. Make sure you've tried all other methods first.
🔍 Fix #4: Check for Physical Damage
Physical damage can prevent your iPhone from turning on. Look for these signs:
- Cracked screen or back - May indicate internal damage
- Dents or bends - Can damage internal components
- Liquid damage indicators - Red dots in SIM tray or charging port
- Loose buttons - Power or volume buttons feel different
💻 Fix #5: Test With a Computer
Sometimes your iPhone might be on but the screen isn't working. Connect to a computer to test:
- Connect your iPhone to a computer with iTunes or Finder
- If iTunes/Finder recognizes your device, the iPhone is actually on
- This indicates a screen or display issue rather than power problem
- Try the force restart method while connected
⏰ Fix #6: Wait and Try Again
If your battery was completely drained, it might take time to charge enough to turn on:
- Leave your iPhone charging for at least 30 minutes
- Use a wall charger, not a computer USB port (faster charging)
- Look for any charging indicators on the screen
- Try turning on after extended charging time
🔧 Fix #7: Try DFU (Device Firmware Update) Mode
DFU mode is a deeper restore option for severe software issues:
⚠️ Advanced Method
DFU mode completely erases your iPhone. Only use this if other methods fail and you have a backup.
- Connect iPhone to computer and open iTunes/Finder
- For iPhone 8+: Volume Up → Volume Down → Hold Side button
- After 10 seconds, release Side button but keep holding Volume Down
- Screen should stay black (if Apple logo appears, start over)
- iTunes/Finder will detect device in recovery mode
🔧 Fix #8: Professional Repair
If none of the above methods work, you likely have a hardware issue that requires professional repair:
- Battery replacement - Old batteries can fail completely
- Charging port repair - Damaged ports won't charge properly
- Logic board issues - May require micro-soldering
- Water damage repair - Needs specialized cleaning and part replacement
💰 Cost-Effective Tip
Get a quote from local repair shops first. Sometimes repair costs more than the iPhone's current value, especially for older models.
🛡️ Preventing Future Issues
To avoid your iPhone not turning on in the future:
- Don't let your battery drain to 0% regularly
- Use genuine or MFi-certified charging cables

- Update iOS regularly for stability improvements
- Use a protective case to prevent physical damage
🍎 When to Contact Apple Support
Contact Apple or visit an Apple Store if:
- Your iPhone is still under warranty
- You have AppleCare+ coverage
- None of these methods worked
- You suspect a hardware defect
