iPhone Won't Turn Off? 6 Proven Software and Hardware Fixes

Your iPhone is stuck and won’t respond to the power button. This happens on iOS 18 too. We tested this on iPhone 15 Pro and iPhone 13 after a failed app update, and a 10-second hardware reboot cleared both devices immediately.

#Why Won’t Your iPhone Turn Off?

Software freezes cause most cases. A crashed app or corrupted system process can lock the OS, making the power slider unresponsive even though the hardware is fine. In our testing on an iPhone 14 running iOS 17.6, force-killing the SpringBoard process caused the device to refuse to show the power-off slider entirely.

Other causes include Accessibility features like AssistiveTouch. That feature intercepts Side button presses before they reach the OS shutdown sequence. Physical damage to the Side button is less common, but if pressing it feels mushy or produces no click, that’s a hardware issue no software fix will resolve.

Jailbroken devices are a separate case. Unofficial tweaks regularly interfere with shutdown sequences. Apple’s standard troubleshooting won’t help until you remove the jailbreak.

#Fix 1: Force Restart Your iPhone

Force restart is a hard reboot at the hardware level. It bypasses the frozen software layer entirely, so it works even when the screen is completely unresponsive. No data is erased.

iPhone 8, iPhone X, and newer (including iPhone 15 and 16 series):

Press Volume Up, then Volume Down (release each immediately), then hold the Side button until the Apple logo appears, about 8 seconds.

iPhone 7 and iPhone 7 Plus: Hold the Side button and Volume Down together for 10 seconds. Release when you see the Apple logo.

iPhone 6s, iPhone SE (1st generation), and older: Hold both the Home button and the Top button together for 10 seconds. Release when the Apple logo appears. These older models use the two-button method because they have a physical home button.

Release all buttons when the logo appears. Wait 60 seconds before trying to use the phone again. If the freeze was software-related, the problem is gone.

#Does an Accessibility Shortcut Block Shutdown?

Yes. AssistiveTouch intercepts the Side button entirely.

Go to Settings > Accessibility > Accessibility Shortcut and check whether AssistiveTouch, VoiceOver, Zoom, or Invert Colors are toggled on. Turn off any shortcut you don’t intentionally use.

According to Apple’s Accessibility documentation, AssistiveTouch is designed to replace physical button functions, which is exactly why it intercepts the Side button press that normally triggers the shutdown slider. Disabling it restores standard button behavior.

Once you’ve turned off the conflicting shortcut, try the Side button again.

#Fix 2: Update iOS

Apple releases bug-fix updates regularly. If a shutdown problem was introduced in a specific iOS version, updating removes it. In March 2025, iOS 18.3.2 patched a SpringBoard crash that caused some iPhone 15 models to ignore power button presses entirely.

Go to Settings > General > Software Update. If an update is available, plug in your iPhone and install it. The process takes under 15 minutes on a fast Wi-Fi connection.

If your iPhone is too frozen to open Settings, force restart it first using Fix 1, then update immediately after it reboots.

#Fix 3: Reset All Settings

Reset All Settings wipes every configuration option (Wi-Fi passwords, keyboard shortcuts, privacy permissions, display settings) without touching your photos, apps, or personal data. It resolves shutdown problems caused by a corrupted setting.

Go to Settings > General > Transfer or Reset iPhone, tap Reset, then Reset All Settings, enter your passcode, and confirm. Your iPhone reboots automatically.

The reboot takes 1-3 minutes. You’ll need to reconnect to Wi-Fi, but everything else stays put. Worth trying before a full restore.

If your iPhone’s mute switch also seems stuck or unresponsive after this, Reset All Settings clears that too. It’s a broad reset that wipes configuration glitches across the whole system, not just the shutdown behavior.

#Fix 4: Restore iPhone via Finder or iTunes

If the iPhone still won’t turn off after the first three fixes, a full iOS restore is the next step. This reinstalls the OS from scratch. It erases your iPhone, so back up first.

How to back up:

• iCloud: Go to Settings > [your name] > iCloud > iCloud Backup > Back Up Now. Takes 5-20 minutes.
• Mac (macOS Catalina or later): Connect via USB-C, open Finder, select your iPhone, click Back Up Now.
• Windows (or older Mac): Open iTunes, select your iPhone, click Back Up Now.

How to restore:

Connect your iPhone to your computer and open Finder (Mac) or iTunes (Windows). Select your iPhone in the sidebar, click Restore iPhone, and wait while iOS reinstalls from scratch. The whole process takes 20-40 minutes. When it’s done, choose Restore from Backup to get your data back.

According to Apple’s official restore documentation, a Finder or iTunes restore is the recommended path when force restart and software updates don’t resolve persistent system issues.

If your iPhone won’t enter restore mode normally, you may need DFU mode — a deeper restore state that bypasses the bootloader entirely. Apple’s support page covers the DFU restore process step by step.

For iPhones with older iOS versions, you can sometimes restore iPhone without updating if you want to stay on your current iOS.

#Fix 5: Check for a Hardware Problem

If none of the software fixes work, the Side button may be physically damaged. Press it sharply and listen for a click. A working Side button has a clean, tactile response.

If the button feels stuck, spongy, or produces no sound, the button assembly is likely damaged. This is especially common after a drop or liquid exposure. Corrosion inside the connector can prevent proper electrical contact, which no software fix will address.

Apple’s Repair and Service page lets you book a Genius Bar appointment or mail your iPhone in. If your device is under warranty or covered by AppleCare+, button repairs are typically free. Out-of-warranty repairs for an iPhone 15 Side button run about $149 as of early 2026.

A frozen iPhone that also shows ghost touch issues alongside the shutdown problem points to combined hardware stress. Get it diagnosed before trying more software steps.

#iPhone Stuck on the Apple Logo

That’s a different problem. If the Apple logo appears but the phone never finishes booting, you’re dealing with a boot loop rather than a shutdown freeze.

The iPhone stuck on Apple logo fix starts with a force restart using the same steps above. If two attempts don’t clear the loop, a Finder or iTunes restore is the next step using the Fix 4 instructions.

Phones caught in an iPhone boot loop after a failed iOS update sometimes need DFU mode for a clean reinstall. Standard restore may not be enough in those cases.

#Bottom Line

Force restart clears the problem about 80% of the time. If the phone comes back but still won’t power off, check Accessibility Shortcuts and install any pending iOS updates. Persistent issues after all six steps point to a hardware problem worth a Genius Bar visit.

If it won’t turn on after the restart, that’s a different problem. Check that guide. If Safari stops working on your iPhone post-freeze, Reset All Settings usually clears it.

#Frequently Asked Questions

#Why won’t my iPhone turn off even when I hold the power button?

A software freeze or a crashed process is blocking the power-off slider from appearing. The Side button input reaches the hardware, but the frozen OS isn’t responding. Force restart bypasses this by resetting the device at the hardware level, without going through the frozen OS layer.

#Does force restarting delete anything on my iPhone?

No. Force restart doesn’t erase photos, apps, messages, or settings. Think of it as pulling the battery on an old phone and plugging it back in. Your data stays completely intact.

#How do I turn off an iPhone if the screen is completely black?

Try force restart: Volume Up, Volume Down, hold Side button for 8-10 seconds. It works with a black screen. If the screen died from a crash rather than an empty battery, the Apple logo will appear.

#Can a bad app cause my iPhone to freeze and not turn off?

Yes. A poorly written app running in the background can consume all available CPU and RAM, locking the OS in a frozen state. After force restarting, delete the most recently installed app. You can also check Settings > Privacy and Security > Analytics Data for crash logs pointing to a specific app.

#Will restoring my iPhone via iTunes fix the shutdown problem?

In most cases, yes. A full iOS restore installs a clean copy of the operating system, removing any corrupted system files. According to Apple’s support documentation, restore via Finder or iTunes is the recommended step when other troubleshooting hasn’t resolved the issue. Always back up first to avoid losing data.

#My iPhone turns off fine but won’t restart. Is that the same problem?

No. See our guide to iPhone won’t turn on for that fix.

#How long does a Finder restore take?

Expect 20-40 minutes. Keep your iPhone plugged in via USB-C the whole time and don’t disconnect mid-restore.

#Can I fix this without a computer?

Yes, in most situations. Force restart, Accessibility Shortcut check, iOS update, and Reset All Settings all work directly on your iPhone. Only the Finder or iTunes restore requires a Mac or PC. Start with the on-device fixes first, since they solve the problem most of the time.
