iPhone 6 Won’t Charge and Shows “Cable Not Supported”

The Issue: Your iPhone 6 refuses to charge and throws the “This cable or accessory is not supported” error. It might only charge after restarting the phone—or sometimes not at all.

How to Fix It:

1. Clean the Lightning Port
Dust or lint inside the charging port can block a proper connection.

• Use a flashlight to check the port.
• Carefully clean it with a toothpick or anti-static brush.
• You can also blow it out using compressed air.

2. Use an Apple-Certified Cable
Third-party or cheap cables often trigger the “unsupported” error.

• Try using an Apple original or MFi-certified Lightning cable.
• Even if the cable works on another device, your iPhone might still reject it if there’s internal damage or poor connectivity.

3. Restart Your iPhone While Plugged In
This trick works for some users:

• Plug in the charger.
• Hold the Sleep/Wake (Power) button until the red slider shows up.
• Slide to power off, then turn it back on after a few seconds.
• See if the phone begins charging normally after restarting.

4. Try Charging From a Different Outlet or USB Port
Wall outlets can sometimes be the issue.

• Try a different wall plug or USB port on your computer.
• Avoid charging via car ports or public USB hubs when troubleshooting.

iPhone 6 Freezes When Charging

The Issue: Your iPhone 6 hangs or becomes unresponsive every time you connect the charger. It goes back to normal once unplugged.

How to Fix It:

1. Use the Original Charger and Cable
Non-certified accessories can cause software glitches or power issues.

• Stick with the charger and cable that came with your iPhone, or use a certified replacement.

2. Switch Power Sources
Charging from an unstable or low-voltage source may cause freezing.

• Try plugging into a different wall outlet or USB port.
• Avoid extension cords or surge protectors while testing.

3. Try a Different Cable and Charger Combo
The charger or cable may be malfunctioning even if it looks fine.

• Use a known-good Apple charger and cable from a friend or another device.
• If the freezing stops, you’ve found the culprit.

4. Check for Software Updates
Sometimes a bug in iOS causes charging-related glitches.

• Go to Settings > General > Software Update and install any available updates.

5. Reset All Settings (Optional)
If the problem continues and you’re sure it’s not hardware, you can reset your settings:

• Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings.
• This won’t delete your data, but it will reset things like Wi-Fi passwords and display preferences.
