How To Fix Auto Lock Greyed Out on Apple iPhone 15 Plus

Auto-lock on iOS devices serves multiple purposes - it conserves battery life, secures your data, and more. But have you encountered the Auto-Lock greyed-out dilemma, fixed at 30 seconds? When this setting becomes inaccessible, it limits your control over screen timeout.

Read on if you’ve encountered a similar problem on your iOS device. In this guide, we’ll explore the possible reasons and offer steps to fix Auto-Lock greyed out on iPhone and iPad devices. If force restarts or settings resets haven’t worked for you, we’ve got alternative solutions. Let’s get started.

Part 1: Why Is Auto-Lock Greyed Out on iOS Device?

There are a few reasons why the Auto-Lock might be greyed out on your Apple iPhone 15 Plus or iPad device, preventing you from adjusting the duration. Here are the most common culprits:

Low Power Mode

When you activate Low Power Mode on your iOS device, you might notice the screen automatically locking after 30 seconds of inactivity. This quick sleep setting, implemented to minimize power usage, explains why the Auto-Lock option appears greyed out and inaccessible.

Screen Time Restrictions

Screen Time restrictions can impact Auto-Lock. For instance, if your downtime schedule blocks all apps, the screen locks itself, even if the Auto-Lock timer hasn’t run out.

MDM Profile Restrictions

If the Auto-Lock is greyed out on your iPad or iPhone and you use it for work or school, a Mobile Device Management (MDM) profile might be the reason. This profile restricts settings, including Auto-Lock. To fix this, contact your IT administrator and ask if they can adjust the MDM profile settings.

Alright, you know the possible reasons why the Auto-Lock option is not working on your iOS device. Still, you might be wondering how to fix the Auto-Lock greyed-out issue. Below are several ways to get your iPad or iPhone Auto-Lock working normally again.

Fix No.1: Disable Low Power Mode

Your iPhone Auto-Lock greyed out because Low Power Mode limits background activities, including the Auto-Lock option. In this mode, you cannot change the Auto-Lock settings. Turn off Low Power Mode to fix this issue and choose your preferred timeout. Here’s how:

  • Step 1: Go to your Apple iPhone 15 Plus or iPad’s Settings app.
  • Step 2: Scroll down and tap Battery. It will show you your device’s battery usage and available settings.
  • Step 3: Turn off the Low Power Mode. Now, the greyed-out Auto-Lock option in Settings should be available again.

Low Battery Mode can stretch your battery life further. But if you need your screen to stay on longer, like while reading an article or watching a video, you can turn it off. It lets you adjust the screen timeout in Settings so it stays awake for as long as you like.

Fix No.2: Check Screen Time Restrictions

You’ve ruled out the Low Power Mode, but the Auto-Lock greyed out on iPad or iPhone remains. If Low Power Mode isn’t causing the problem, your screen time settings might be the issue. Some app restrictions can limit your screen use to specific times, causing it to lock automatically. Resolve this by removing limits, such as downtime and app restrictions, or turning it off.

  • Step 1: Open the Settings app on your iOS device.
  • Step 2: Go to Screen Time, then scroll down.
  • Step 3: Tap Turn Off Screen Time.

Fix No.3: Remove MDM Configuration Profile

A configuration profile is a file that contains settings and restrictions that can be applied to an iOS device. Organizations, schools, or IT administrators often use it to manage devices remotely and enforce specific configurations. Once installed, the settings within a profile override the Apple iPhone 15 Plus device’s default settings. It can include restrictions related to security, network access, app usage, and more.

Since an MDM configuration profile causes limitations, like the greyed-out Auto-Lock on iPad, removing it can be the solution. Doing so frees your iOS device from external settings imposed by the profile. Then, it could allow you to adjust the Auto-Lock time setting as you normally would.

  • Step 1: See the configuration profiles you installed on your iOS device.

  • Go to Settings> General > VPN & Device Management on your Apple iPhone 15 Plus.

  • Go to Settings> General > Profiles & Device Management on your iPad.

  • Step 2: Select the configuration profile you need to delete.

  • Step 3: Tap Remove Profile, enter your device passcode, then tap Remove.

Fix No.4: Remove Network Settings Installed by MDM

Businesses often use Mobile Device Management (MDM) to remotely manage their employees’ iPhones and iPads. MDM lets IT admins push software updates, restrict apps, and remotely wipe a lost device. This keeps corporate data safe and devices under control, whether the company or the employee owns them.

If you’re having trouble with a greyed-out Auto-Lock timeout setting, disassociating your device from MDM might be an option. But remember, this is a big step. Make sure you follow your company’s authorized procedures to avoid unintended consequences.

If your IT team gives the green light, you might also be able to remove the network settings installed by MDM. Just proceed with caution, as messing with these settings could lead to instability or data loss. Here’s how:

  • Step 1: Open the Settings app on your iOS device.
  • Step 2: Navigate to General > Profile or VPN & Device Management (or a similar section).
  • Step 3: Select the management and tap Remove Management.

If the option is unavailable, only the person who used Apple Configurator 2 or handles your company’s mobile device management platform can remove it.

Fix No.5: Use Dr.Fone To Bypass MDM Lock Without Data Loss

Unfortunately, manually removing profiles can be tricky, especially if they’re associated with MDM, Apple School Manager, or supervised configurations. These often require the removal of passwords, admin privileges, or complete data wipes. But there’s good news. Wondershare Dr.Fone - Screen Unlock (iOS) provides a simpler and safer solution.

Apple iPhone 15 Plus Asking for Passcode after iOS 17/14 Update, What to Do?

If you’ve recently updated your iOS iPhone and iPad to the iOS 17/14 operating system, you may notice a bit of a bug where the Apple iPhone 15 Plus displays the passcode lock, even if you haven’t got a security code in place.

This obviously means you won’t be able to access your phone, and in many cases, you’re going to want to get back into your phone as quickly as possible. However, this may be easier said than done. Fortunately, today we’re going to go through multiple solutions to help you get your device working as it should!

Part 1. Don’t try passcodes blindly

One of the worst things you can do when faced with this situation is to enter passcodes blindly. Perhaps you’re trying random numbers and letters, or you’re trying passwords you’ve used in the past. If you get it wrong, you’re going to be locked out of your device for a long time.

The more times you get your code wrong, the longer you’ll be locked out, so avoid doing this at all costs, so make sure you move straight onto these approaches to get your phone working as quickly as possible.

Part 2. 5 ways to unlock iPhone after iOS 17/14 Update

2.1 Try a default passcode in your family

While we said, you shouldn’t type in random numbers to try and guess the password, of course, if you have a standard family passcode that you use across all iOS devices, perhaps an admin password or just something you use for everything, it can be well worth a try.

iphone random passcodes

In reality, you get three attempts to put a passcode in before it locks you out, so try two passcodes that your family uses to see whether this will easily unlock your device. If you brought your device preowned and still have contact with the owner, they may have a passcode you can try.

2.2 Unlock iPhone with an unlock tool

The second approach you can take if you don’t know the passcode and can’t get it unlocked is to use a powerful software solution known as Dr.Fone - Screen Unlock (iOS) . This Wondershare software application completely unlocks your phone, even if you don’t know the passcode.

This software is easy to use and incredibly simple, yet it gets the job done. If you’re looking for a quick way to get your iOS device back up and running with full access after an iOS 17/14 update, it doesn’t get much better than this. Here’s how it works;

Step 1. Download and install the Dr.Fone - Screen Unlock (iOS) software to either your Mac or Windows PC and open it, so you’re on the homepage. Connect your iOS device to your computer using the USB cable and wait for the software to recognize your device.

When it does, close iTunes if it automatically opens and clicks the Screen Unlock option from the main menu.

Step 2. Click the Unlock iOS Screen option.

Step 3. You will now need to put your device in DFU mode, also known as Recovery Mode. Fortunately, this is easy thanks to the on-screen instructions where you will hold down the volume down and power button for a few seconds.

Step 4. Once Dr.Fone - Screen Unlock (iOS) has detected your device in DFU Mode. You’ll be able to select which device you’re using and what firmware you want to be repaired; in this case, iOS 17/14.

Step 5. Once everything has been confirmed and you’re happy to continue, press the Unlock option. The program will do its thing, and when it’s done, the software will say you’re able to disconnect your Apple iPhone 15 Plus and use it without a lock screen!

That’s how easy Dr.Fone - Screen Unlock (iOS) makes the entire unlock process!

2.3 Restore an old backup from iTunes

Another key way that some users have found to unlock their device after an update is to restore their device to an older version, aiming to put your device back into a position where it didn’t have a lock screen.

It’s only possible to do this if you’ve backed up your iOS device in the past (which is why you’re encouraged to back up regularly), and it can all be done through the iTunes software on either your Mac or Windows computer. Here’s how it works;

Step 1. Ensure you’re running the latest version of iTunes and then connect your iOS device to your Mac or Windows computer using the official USB cable. This should automatically open the iTunes window.

Step 2. In iTunes, click the symbol representing your device and then click Summary. On this screen, you’ll be able to choose the Restore iPhone option at the top to begin the restoring process.

Step 3. Follow the onscreen instructions where you’ll choose which backup file you want to use before iTunes, then restores your device. When the software has completed the process, you’ll be able to disconnect your Apple iPhone 15 Plus and use it without a lock screen!

2.4 Restore in recovery mode

In some cases, restoring your device using just iTunes will not be good enough, and it won’t have the effect you’re looking for; in this case, restoring your device with no lock screen after an iOS 17/14 update.

If the above method of restoring your device via iTunes doesn’t work, or you haven’t got a backup file to load, you’ll need to restore your device using a move known as Recovery Mode, or DFU mode. This will hard reset your device and get it working to its full potential.

Here’s how to do it. (Note, the process will differ slightly depending on which model of iPhone you’re using).

Step 1. Press and hold the volume up button for about one second, and then switch and press the Volume Down button for the same amount of time. You can then hold the side button (on devices without a home button), and the following screen should appear after a few seconds.

drfone home

Step 2. Now connect your Apple iPhone 15 Plus to your computer with iTunes and wait for iTunes to open. Make sure you’re running the latest version of iTunes before connecting up your device. Also, make sure you’re using the official USB cable for the most stability.

Step 3. iTunes should automatically detect that your device is in Recovery Mode and automatically restore your device to a default state without a lock screen. Wait until this process is completed before disconnecting your device and using it as normal.

2.5 Use Find My iPhone feature in iCloud

The fifth and final approach you can take to removing a lock screen from your recently updated iPhone or iPad when faced with the iOS 17/14 glitch is taking advantage of the integrated Apple technology and features are known as Find My iPhone.

While this feature originally allows you to literally find your Apple iPhone 15 Plus in the situation where it’s lost and offers many other security features to help ensure your device and data don’t fall into the wrong hands, you can also use it to remove your device unwanted lock screen.

Of course, this will only work if the Find My iPhone features have been enabled in the past, so make sure you’re using it to get it to work. Here’s how to use the feature to get your phone access back.

Step 1. From your computer, iPad, tablet, or mobile web browser, head over to iCloud.com and log into your iCloud account using the login in button at the top of the screen.

find my iphone

Step 2. Once signed in, scroll down the menu of features and select the Find iPhone feature. Click on the All Devices option at the top.

Step 3. From the list of devices connected to your account, click the Apple iPhone 15 Plus device name with the locked screen and then click the Erase option. This will clear everything from your device, much like the process we’ve spoken about in the methods above.

Leave the Apple iPhone 15 Plus device to erase, and once completed, you’ll be able to pick up and use your phone as normal without a lock screen. You should also now be able to update to iOS 17/14 without any problems!

Summary

And there you go, the five key ways you need to know when it comes to removing an unwanted lock screen from your iOS device after an iOS 17/14 update. We highly recommend the Dr.Fone - Screen Unlock (iOS) since the software makes the whole process incredibly easy, especially when managing any problems you may have on your iOS device!
