iPhone 6 or 6 Plus Not Charging or Powering On? Here’s How to Fix It

Got power problems on your iPhone 6 or 6 Plus? Whether it’s charging too slowly, not turning on, or stuck after a screen replacement, you’re not the only one. These older models are still hanging in there for many users, but issues like these are pretty common. Here’s how to troubleshoot each one step by step.

iPhone 6 Charging Very Slowly

If your iPhone 6 takes 12 hours to reach 50%, something’s definitely off.

Try this:

• Inspect the charging port: Use a flashlight and check for dirt or lint. Gently clean it out with a toothpick or anti-static brush.
• Check for battery swelling: Lay the phone on a flat surface. If it wobbles, the battery could be swollen. You’ll need a replacement.
• Try a different charger and cable: Use a certified Lightning cable and a different wall adapter or test with another Apple device’s charger.
• Update your iOS: Go to Settings > General > Software Update.
• Charge while powered off: Turn the phone off completely and let it charge for an hour. If charging improves, a background process or app may be draining power.
• Factory reset (last resort): Go to Settings > General > Reset > Erase All Content and Settings. Set up as new before reinstalling any apps.

iPhone 6 Error 53 (Usually After Update or Repair)

Error 53 usually shows up when trying to update via iTunes, especially after replacing parts like the home button.

Fix options:

• This used to be a serious issue tied to Touch ID validation, but Apple released an iTunes update that bypasses this error for non-secure recovery.
• Make sure you’re using the latest version of iTunes
• Follow Apple’s official recovery guide: https://support.apple.com/en-us/HT205628

iPhone 6 Not Charging After iOS Update

If your phone suddenly stops charging after an iOS update:

What to try:

• Force restart: Hold Power + Home for 30 seconds until the Apple logo appears.
• Reset all settings: Go to Settings > General > Reset > Reset All Settings
• Use a known-good charger: Rule out cable or adapter issues
• DFU restore (last resort):
  1. Connect your phone to your computer
  2. Launch iTunes (or Finder on macOS Catalina or later)
  3. Put your iPhone into DFU mode and restore

iPhone 6 Won’t Power On After Screen Replacement

Just changed your screen and now the phone won’t boot at all?

Check these:

• Double-check the LCD and digitizer connectors—one loose flex cable will prevent booting
• Ensure the battery connector is properly seated
• Try a hard reset (Power + Home for 30 seconds)
• If still no response, you may have damaged something during the repair—get it inspected by a repair tech

iPhone 6 Plus Only Turns On With Hard Reset

After a screen swap, does your phone only boot after a hard reset?

Possible causes:

• Faulty power or home button hardware
• Improper flex cable installation or pinched ribbon cable
• Software glitch—try Reset All Settings or a factory reset

If the issue continues, open the device and recheck connections—or bring it to a repair shop for a closer look.

iPhone 6 Screen Flickering and Frozen

If your screen is flickering, unresponsive, and nothing seems to fix it—even after a reset:

Likely hardware issue—especially if:

• You dropped the phone recently
• There’s a history of water exposure
• You’ve already tried restoring via iTunes or Find My iPhone

At this point, your best option is to bring the phone to a certified repair technician for a physical inspection.
