The iPhone 12 Pro Max is Apple’s flagship model from its 12 series, boasting an array of impressive features. However, like any tech product, it’s not exempt from occasional issues. Understanding and diagnosing these issues can save users time and potentially money. Here’s a rundown of common iPhone 12 Pro Max problems and how to spot them.

1. Connectivity Issues

Issue: Many users have reported problems connecting to Wi-Fi networks or maintaining a stable connection.


  • Ensure Wi-Fi is turned on and you’re within range of your network.
  • Check for any iOS updates, as Apple occasionally releases fixes for connectivity problems.
  • Reset your network settings by going to Settings -> General -> Reset -> Reset Network Settings. This will revert any network settings to their default and might solve the issue.

2. Green Tint on Display

Issue: Some users have noticed a slight green tint on their screens, particularly when the background is supposed to be black.


  • Check your screen at various brightness levels. The green tint is often more noticeable at lower brightness.
  • Ensure you’re using the latest iOS version. Apple is aware of the issue and has released updates aimed at fixing this.
  • If the issue persists, it may be a hardware problem, and visiting an Apple store might be the best course of action.

3. Rapid Battery Drain

Issue: Some users experience their iPhone 12 Pro Max losing battery power more rapidly than expected.


  • Go to Settings -> Battery to check which apps are consuming the most power.

  • Ensure you’re using an Apple-certified MagSafe charger.
  • Check if there’s any debris or foreign objects on the back of the phone or on the MagSafe charger that might hinder the connection.
  • Make sure your iOS is updated, as some charging issues can be fixed through software updates.

Issue: The phone unexpectedly shuts down or restarts.


  • This could be due to a rogue app. Monitor if shutdowns happen when using a specific app.
