If your iPhone won't turn off, you may be worried that your phone's battery is going to run out or that your iPhone is broken.
Those are both valid concerns. An iPhone that's stuck on is a rare situation, but if it's happening to you, you need to understand what's going on so you can know how to fix it.
Reasons Why Your iPhone Won't Turn Off
The most likely culprits behind an iPhone not turning off are:
1. It's frozen due to software problems
2. The Sleep/Wake button is broken
3. The screen is broken and isn't responding to touches. If this is the case, skip directly to Step 4.
How to Fix an iPhone That Won't Turn Off
If you're dealing with an iPhone that's stuck on and won't go off, there are three steps you can take to try to fix it before involving Apple.
All of these steps assume that you've already tried the standard way to turn off your iPhone—holding down the Sleep/Wake button and then sliding the Power Off slider—and that it didn't work.
If that's the situation you're in, try these steps next.
Step 1: Hard Reset
The first, and simplest, way to shut down an iPhone that won't turn off is using a technique called a hard reset.
This is very similar to the standard way of turning your iPhone on and off, but is a more complete reset of the device and its memory.
Don't worry: you won't lose any data. Only use a hard reset if your iPhone won't restart any other way.
To hard reset your iPhone:
1. Hold down the Sleep/Wake button and the Home button at the same time. If you have an iPhone 7 series phone, hold down volume down and Sleep/Wake.
2. The power off slider should appear on the screen. Keep holding both buttons.
3. The screen will go black.
4. The Apple logo will appear on the screen. Let go of both buttons and the iPhone will restart like normal.
When the phone is finished restarting everything should work fine again.
Step 2: Enable AssistiveTouch and Turn Off Via Software
This is a super-cool trick that's most useful if one of the physical buttons on your iPhone—Sleep/Wake or Home, most likely—is broken and can't be used to turn off your phone.
In that case, you need to do it through software.
AssistiveTouch is a feature built into the iPhone that puts a software version of the Home button on your screen.
It's designed for people with physical conditions that make it hard for them to press the button,
but lots of people without those conditions use it for the cool features it offers. Start by enabling Assistive Touch:
1. Tap Settings
2. Tap General
3. Tap Accessibility
4. In the Interaction section, tap AssistiveTouch
5. On the AssistiveTouch screen, move the slider to on/green and a new icon will appear on your screen.
That's your new software-based Home button.
With this new Home button enabled, follow these steps to turn off your iPhone:
1. Tap the software Home button
2. Tap Device
3. Tap and hold Lock Screen until the Power Off slider appears
4. Move the slider from left to right to turn off your iPhone.
Step 3: Restore iPhone from Backup
But what if a hard reset and AssistiveTouch haven't solved your problem?
In that case, the problem that's causing your iPhone to stay on probably has to do with the software on your phone, not the hardware.
It's hard for the average person to figure out whether that's a problem with the iOS or an app you've installed, so the best bet is to restore your iPhone from backup.
Doing this takes all of the data and settings from your phone, deletes and then reinstalls them to give you a fresh start.
It won't fix every problem, but it does fix a lot. Here's what you need to do:
1. Connect your iPhone to the computer you normally sync it with
2. Open iTunes if it doesn't open on its own
3. Click the iPhone icon in the top left corner, beneath the playback controls (if you're not already in the iPhone management section, that is)
4. In the Backups section, click Back up Now. This will sync your iPhone to the computer and create a backup of your data
5. When that's done, click Restore Backup
6. Follow on the onscreen prompts to select the backup you just created in step 4
7. Follow the onscreen steps and, after a few minutes, your iPhone should start up like normal
8. Disconnect it from iTunes and you should be good to go.
Step 4: Visit Apple for Help
If none of these steps have solved your problem, and your iPhone still won't turn off,
your problem may be bigger, or just a lot trickier, than you can solve at home. It's time to bring in the experts: Apple.
You can get phone support from Apple (charges will apply if your phone is no longer in warranty).
Check out this page on Apple's site for its list of support phone numbers around the world.
Alternatively, you can go to an Apple Store for face-to-face help.
If you prefer that, be sure that you make an appointment ahead of time.
There's a lot of demand for tech support at Apple Stores and without an appointment you'll probably wait a really long time to speak to someone.
