iPhone Won't Charge - Complete Fix Guide

⚡ Quick Checks First

Before diving into fixes, rule out the obvious:

• Is the outlet working? Try a different outlet or USB port
• Is the cable damaged? Look for fraying, kinks, or bent connectors
• Is the charger working? Test it with another device
• Is your iPhone extremely hot or cold? Temperature extremes can prevent charging

🧹 Fix #1: Clean the Charging Port

This fixes the problem about 70% of the time. Pocket lint and debris accumulate in the Lightning or USB-C port and block the connection.

How to clean safely:

1. Turn off your iPhone
2. Use a wooden or plastic toothpick (NOT metal — it can damage the pins)
3. Gently scrape along the back wall of the port
4. Use short, light strokes to pull debris out
5. Shine a flashlight in to check for remaining lint
6. Try charging again

Pro tip: Compressed air can push debris further in. Stick with the toothpick method.

🔌 Fix #2: Try a Different Cable

Cables fail more often than you'd think, especially non-Apple cables:

• Borrow a cable from someone else to test
• Make sure you're using an MFi-certified cable (look for the "Made for iPhone" badge)
• Cheap cables can damage your phone or simply not work

🔄 Fix #3: Force Restart Your iPhone

Software glitches can prevent charging. A force restart often fixes this:

iPhone 8, X, and later (including iPhone 15/16):

1. Press and quickly release Volume Up
2. Press and quickly release Volume Down
3. Press and hold the Side button until you see the Apple logo

iPhone 7:

1. Hold Volume Down + Side button together until Apple logo appears

iPhone 6s and earlier:

1. Hold Home + Top/Side button together until Apple logo appears

⚙️ Fix #4: Check for Software Updates

Apple sometimes releases updates that fix charging bugs:

• Go to Settings → General → Software Update
• Install any available updates
• If your battery is too low, plug in while updating (use a computer USB port if wall charging isn't working)

🔋 Fix #5: Check Battery Health

A severely degraded battery might not charge properly:

• Go to Settings → Battery → Battery Health & Charging
• Check Maximum Capacity — below 80% means the battery is worn
• If you see "Service" warning, the battery needs replacement

🔧 Fix #6: Try Wireless Charging

If you have an iPhone 8 or later, try wireless charging to isolate the issue:

• If wireless charging works but wired doesn't → charging port issue
• If neither works → likely battery or logic board issue

🏭 Fix #7: Reset All Settings

This resets system settings without erasing your data:

• Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings
• Enter your passcode
• This resets Wi-Fi passwords, wallpaper, and settings but keeps your apps and data

⚠️ When It's a Hardware Problem

If nothing above works, you likely have a hardware issue:

• Damaged charging port — pins bent, corroded, or worn out
• Failed battery — won't hold or accept a charge
• Logic board issue — charging circuit damaged (less common)
• Water damage — corrosion inside the phone
