Why Does My iPhone Won’t Turn On After iOS 18 Update?

The update process can sometimes cause unexpected glitches, leaving your iPhone unresponsive. Understanding the potential causes behind this problem is the first step toward finding an effective solution.

Here are a few reasons why your iPhone might not turn on after the iOS 18 update:

Software Bugs: New iOS releases can sometimes carry bugs that affect system performance, causing the device to freeze or fail to power on after the update.

Failed Update Process: If the update didn’t complete properly due to an interrupted internet connection or a battery issue, it may lead to your iPhone not working after update iOS 18.

Insufficient Storage: If your iPhone was low on storage before the update, it might not have enough space to process the new system files, leaving it stuck in an unresponsive state.

Hardware Incompatibility: Older iPhone models may struggle with the demands of iOS 18, leading to performance issues or complete failure to boot.

Battery Drain: Sometimes, the update process can drain your iPhone’s battery, causing it to shut down and not power on until recharged.

How to Fix iPhone Won’t Turn On After iOS 18 Update?

In case of your iPhone not turning on after update, don’t panic – there are several methods to try that may help fix it. Below is a quick comparison of these methods to help you decide which one might work best for your situation.

Common Ways to Fix iPhone Won’t Turn On After iOS 18 Update

If your iPhone is not working after the iOS 18 update, several basic troubleshooting methods can help restore your device to normal. These methods range from force restarts to more advanced solutions like Recovery and DFU Mode. However, it’s important to note that while these methods have been known to work in many cases, they are not always the most reliable, especially if the problem stems from more complex system errors. If you want to solve the issue quickly and safely, opting for a specialized third-party tool may offer the best results without the hassle of trial and error.

1. Restore iPhone Via Recovery Mode

If your iPhone won’t turn on after an update, using Recovery Mode to reinstall iOS can often resolve the problem. Recovery Mode is designed to troubleshoot system failures by restoring your iPhone to factory settings, which can help fix any glitches caused by the iOS 18 update. Although this method can be effective, it typically erases all your data unless you have a backup. Here’s how to use it:

Step 1: Download and install ReiBoot on your computer and connect your iPhone to it using a Lightning cable. Launch ReiBoot and click “Enter” in the bottom-left corner.

Step 2: Within one minute, your iPhone will enter Recovery Mode.

Step 3: Head to iTunes and click “Restore.”

2. Fix iPhone Won’t Turn On Via DFU Mode

If Recovery Mode doesn’t fix the issue, you can try DFU (Device Firmware Update) Mode. It is a comprehensive solution for deeper system issues that might be preventing your iPhone from turning on after the iOS 18 update. Be aware that DFU Mode will erase all data on your device, so you should only use this option if you have a recent backup. Here’s how to fix your iPhone not working after iOS 18 update via DFU mode.

Connect your iPhone to your computer and launch iTunes (or Finder if you’re using macOS Catalina or later). To enter DFU mode:

First, press and quickly release the Volume Up button, followed by the Volume Down button.
Next, press and hold the Power button until the screen goes black (about 10 seconds).
While still holding the Power button, press the Volume Down button for 5 seconds.
After that, release the Power button but continue holding the Volume Down button for another 10 seconds.

iTunes (or Finder) should now detect your iPhone in DFU Mode and display a prompt for restoration. Select the “Restore” option to erase your device and return it to factory settings, which could fix any software problems that are preventing your iPhone from turning on.

3. Force Restart iPhone

Sometimes, the problem can be as simple as your iPhone getting stuck during the update process, and a force restart can quickly resolve this. This is often the first method to try when your iPhone is unresponsive after an update, as it’s quick and non-invasive. Here’s how to force restart:

Step 1: Press and release the Volume Up button, then the Volume Down button, and finally press and hold the Power button until the Apple logo appears.

Step 2: This method is simple, but it may not work if the issue is caused by a more significant software error. Still, it’s a good first step before moving on to more involved solutions.

4. Recharge Your iPhone [Possibly Ineffective]

Another basic step, especially if your iPhone seems completely dead after the update, is to check whether the battery has simply drained during the iOS 18 installation process. While less likely, especially with a newer phone, it’s worth trying if your iPhone shows no signs of life. Here’s what to do:

Connect your iPhone to a charger using a certified cable and leave it to charge for at least 30 minutes.
After charging, attempt to turn the phone on by pressing the Power button.
This method might work if the issue is related to the battery, but it’s generally less effective when the problem occurs after a software update.
