There are several reasons why your iPhone 12 might be turning off by itself. One possibility is that the battery is not properly connected. Another possibility is that there is a problem with the software. In some cases, the issue may be caused by a hardware defect.

I’ve been writing about technology for several years now, and I’ve seen a lot of different issues with iPhones. In my opinion, the most common cause of an iPhone turning off by itself is a software problem. This can be caused by a variety of things, such as a buggy app or a corrupted iOS update.

Why Does My iPhone 12 Turn Off by Itself?

Experiencing your iPhone 12 shutting down unexpectedly can be frustrating and concerning. To resolve this issue effectively, it’s crucial to troubleshoot potential causes and implement appropriate solutions. This comprehensive guide will assist you in diagnosing and resolving the problem of your iPhone 12 turning off on its own.

I. Troubleshooting Hardware Issues

Examine Physical Components: Inspect the charging port for any dirt, debris, or damage. Ensure that your cables are functioning correctly and aren’t frayed or broken. Carefully examine the battery for any signs of swelling or other abnormalities. Additionally, check the power and volume buttons to make sure they’re not stuck or unresponsive.

II. Identifying Software Glitches

Update iOS: Bugs and glitches in the iOS software can occasionally cause unexpected shutdowns. Downloading and installing the latest iOS update can resolve these issues.

Safe Mode Diagnostics: Corrupted or incompatible apps can also trigger the problem. To identify the culprit, restart your iPhone in Safe Mode. In this mode, only essential apps are loaded, allowing you to pinpoint the problematic app.

Factory Reset: If other troubleshooting methods fail, consider performing a factory reset. This will erase all data and settings from your iPhone, potentially resolving software malfunctions.

III. Managing Battery Settings

Optimize Battery Life: Adjust the screen brightness to a lower level to conserve battery power. Disable unnecessary background app refresh and location services to minimize battery drain.

Battery Health Optimization: Prevent excessive charging and discharging cycles by avoiding keeping your iPhone constantly plugged in or letting it drain completely. This helps prolong battery lifespan and stability.

IV. Resolving Power-Related Issues

Low Power Mode: Check if your iPhone has entered Low Power Mode without your knowledge. This mode automatically activates when the battery level drops below 20%, conserving power by limiting certain functions.

Overheating: Excessive heat can cause the iPhone to shut down as a protective measure. Avoid using the device in extremely hot environments and ensure proper ventilation.

Network Problems: Contact your wireless carrier to rule out any network-related issues that might be causing the shutdowns.

V. Diagnosing Other Possible Causes

Physical Damage: Inspect your iPhone for any signs of physical damage, such as cracks, dents, or water exposure. Such damage can affect the device’s internal components and lead to unexpected shutdowns.

Hardware Defects: In rare cases, manufacturing flaws or hardware defects can cause the issue. Consider consulting an authorized Apple service provider for professional diagnostics and repairs.

By following these troubleshooting steps and addressing potential causes, you can resolve the issue of your iPhone 12 turning off by itself. Remember to regularly update your iOS software, optimize battery settings, and handle your device with care to minimize the risk of such occurrences in the future.


Troubleshooting the reasons behind why an iPhone 12 turns off by itself can involve a range of factors, from hardware issues such as charging port damage to software glitches like outdated iOS versions. By following the outlined troubleshooting steps, users can diagnose and resolve the problem, whether it’s adjusting battery settings, resolving power-related issues, or addressing physical damage. If the issue persists despite these measures, it’s recommended to consult with an authorized Apple service provider for expert diagnostics and repairs to restore the iPhone 12’s functionality. Understanding the potential causes of this issue empowers users to effectively troubleshoot and maintain the optimal performance of their device, ensuring a seamless and reliable user experience.
