The iPhone 6S Plus is still a solid phone with its big 5.5-inch display, strong hardware, and reliable software updates. But even well-built devices can run into issues over time. In this guide, we’ll walk you through fixes for common problems like black screen issues, random restarts, and charging problems on the iPhone 6S Plus.
iPhone 6S Plus Screen Went Black
Problem:
After dropping the phone, the iPhone 6S Plus screen sometimes flickers on when picked up, but mostly stays black. Touchscreen still works in the background.
Solution:
First, force restart the iPhone:
- Press and hold the Home button and the Sleep/Wake (Power) button at the same time.
- Keep holding for about 10 seconds until the Apple logo appears.
If the screen stays black:
- Try restoring the phone using DFU Mode:
- Install the latest iTunes on your computer.
- Connect your iPhone to the computer and open iTunes.
- Press and hold the Home and Power buttons together.
- Keep holding even after you see the Apple logo, until the recovery mode screen appears.
- Choose Update in iTunes to reinstall iOS without erasing your data.
If none of these work, the drop likely damaged the display or internal components. Bring the phone to a repair center for a full hardware check.
iPhone 6S Plus Screen Is Black After Screen Replacement
Problem:
After cracking the screen and replacing it, the phone still has a black screen, even though it vibrates for calls and notifications.
Solution:
This sounds like a hardware issue — either the new replacement screen is defective, or deeper damage happened during the drop.
Next step: Take the phone back to a trusted service center for diagnostics and another screen replacement if necessary.
iPhone 6S Plus Randomly Restarts
Problem:
The iPhone 6S Plus keeps turning itself off and back on in a loop. Changing the battery and restoring the software didn’t fix it.
Solution:
This points to a likely hardware failure, usually a bad power IC (integrated circuit) on the motherboard.
- Unfortunately, this isn’t something you can fix yourself.
- Bring the iPhone to Apple or a professional repair shop for a full logic board diagnosis and possible IC replacement.
iPhone 6S Plus Not Charging, Not Turning On
Problem:
The iPhone 6S Plus doesn’t charge or turn on. Other chargers work on different devices, but not this phone.
Solution:
First, clean the charging port:
- Use a can of compressed air to carefully blow out dust or debris from the port.
Then, try:
- A different Lightning cable and wall adapter.
- Charging the phone for at least 30 minutes before attempting to turn it on.
If it still won’t charge or power on:
- The charging port, battery, or even motherboard could be damaged.
- Bring the device to a repair center for inspection and possible replacement parts.
If you’re dealing with any of these issues on your iPhone 6S Plus, following these steps can help you figure out whether it’s a quick fix or time to visit a service technician.
