iPhone Randomly Shuts Off: Troubleshooting and Repair Guide

Is your iPhone shutting off randomly? Don’t worry, you’re not alone. This frustrating issue can be caused by a variety of factors, and in this guide, we’ll walk you through the troubleshooting steps to help you identify and fix the problem.

Before we dive into the troubleshooting process, make sure to consult the guide for your specific iPhone model. This will ensure that you’re following the correct steps for your device.

Causes of iPhone Randomly Shutting Off

There are several reasons why your iPhone might be shutting off randomly. Here are some of the most common causes:

Software Corruption or Conflict

Software corruption or conflict can cause your iPhone to shut off unexpectedly. This can occur due to a botched update, an app that conflicts with your device’s functionality, or even malicious software.

To attempt to correct this, perform a reinstall of the operating system. If your phone will stay booted for long enough, you can try this from within the settings menu. Otherwise, you’ll need to get it into recovery mode to initiate this process.

Faulty or Worn Battery

As we all know, rechargeable batteries degrade over time. This can lead to unexpected shutdowns. If your iPhone’s battery is old or damaged, it may be causing the shutdowns.

Replace the battery to see if this resolves the issue.

Missing Sensor Data

Starting with the iPhone X, Apple rolled out a sensor check routine as part of normal function. Any sensor in a predetermined list needs to send out a signal every 180 seconds, or the phone will restart as a protective measure.

If you suspect that missing sensor data is causing the shutdowns, try ejecting your SIM tray and see if this resolves the issue.

Faulty Peripheral

Disruption of necessary communications to connected hardware can also cause shutdowns. If you’ve tried the above steps and the issue persists, it’s possible that a faulty peripheral is the culprit.

Check your peripherals and try disconnecting them one by one to see if this resolves the issue.

Liquid Damage

Liquid damage can cause all sorts of problems, including shutdowns. If your iPhone has been exposed to water, it’s possible that this is the cause of the issue.

Try leaving your iPhone in a dry, cool place for a few days to see if this resolves the issue. If not, you may need to seek professional repair.

Logic Board

The logic board is the hub for the vast majority of an iPhone’s functionality. Any number of the small components on the board may have failed or become damaged, and is a safe assumption of cause if nothing else on this page has worked.

If you suspect that the logic board is the cause of the issue, it may be time to seek professional repair.
