If you are wondering How to Fix the iPhone 15 Pro Max not turning on, you must try out the best and easiest ways to fend off the issue discussed below.

Fix 1. Check the Charging Cable and its Condition

If your iPhone 15 isn’t turning on, examine the charging situation and the lightning cable. Ensure you give your phone a reasonable charge, then wait a few minutes before turning it on again.

Test your charger by plugging it into other iPhones to see if it charges them properly. If it doesn’t, you might need to get a new charger.


Always stick to the original lightning cable and charger with your iPhone 15 to maintain its smooth operation and battery health. This way, you’re addressing common issues that could be preventing your iPhone from powering up.

But if Charging the phone also doesn’t work for you, then you should try the following method, which can be an issue for this!

Fix 2. Clean the Charging Port and the Cable

After using it for a while, the charging ports of your iPhone sometimes have dust particles, which you need to clean from time to time. You can look closer with a magnifying glass to inspect the charging port.

Gently clean the charging port using a small tweezer and a microfiber cloth. Be cautious not to harm the charging port during the cleaning process.


After the port is clean, reconnect the charging cable and check if the charging icon appears on the display. If not, proceed to the following method.

Fix 3. Force Restart Your iPhone 15 Pro Max

A force restart is one solution you must follow when your iPhone 15 is stuck on the black screen. Follow these steps to restart your device:-

Fix 4. Charge Using Different Methods

If your iPhone 15 is not turning on even when trying all these steps, you can troubleshoot the issue by trying various charging methods, which could be a lifesaver.


First, Change the charging brick and use a different wall outlet. Let the device charge and see if it powers up.

If the problem persists, switch to charging via your computer’s USB port. This helps determine whether the issue is a drained battery or a deeper hardware problem.

If your iPhone shows signs of life when connected to the computer, the trouble might be with the charging brick. Ensure that you buy an Apple MFI-certified charging cable for optimal results.

No computer or spare charging adapter? No worries. Experiment with a wireless charger. If your iPhone 15 has a charging port problem, a wireless charger can still juice up the battery.


Remember that wireless charging is slower, so give it an hour and check if your device springs back to life.

Fix 5. By Using Recovery Mode

Sometimes, after your phone gets a software update, it might get stuck or freeze. In that case, you need to use Recovery mode and a PC. Follow these steps:-

  1. Connect your iPhone to your computer using a lightning cable.
  2. Open iTunes or the Finder app. Remember, your phone should be paired with your Mac or iTunes on Windows for Recovery Mode to work.
  3. Press the Volume Up on your iPhone and release it quickly.
  4. Now, do the similar for the Volume Down button.
  5. Hold the “Side button.” Keep holding it even when the Apple logo appears. After a few seconds, Recovery Mode will be on.
