iPhone X Delayed Lock? Here’s Why It Happens & The Real Fix!

There’s a delay when you lock your iPhone X and you’re not sure why. You probably noticed it when you pressed your iPhone’s side button, but the screen took a second or two to actually lock. I’ll explain why your iPhone lags after you tap the side button and show you how to fix the iPhone X delayed lock problem!

Why Is There A Delay When I Lock My iPhone X?

There’s a delay when you lock your iPhone X because it has to determine whether you’re going to double-press or triple-press the side button.

Double-pressing the side button activates Apple Pay and triple-pressing the side button opens your Accessibility shortcuts. By turning off Apple Pay by double-clicking the side button and your Accessibility shortcuts, we can eliminate the iPhone X delayed lock problem.

How To Turn Off Double-Click To Apple Pay

Open the Settings app and tap Wallet & Apple Pay. Then, turn off the switch next to “Double-Click Side Button”. You’ll know it’s off when the switch is positioned to the left.

How To Turn Off Accessibility Shortcuts

Open the Settings app and tap Accessibility. Then, scroll all the way down to the very bottom of the screen and tap Accessibility Shortcut.

Here you’ll find a list of all the Accessibility shortcuts you can set up on your iPhone. Make sure there aren’t any checkmarks next to the items in the list!

If you see a checkmark, that means the Accessibility shortcut is on. To turn it off, simply tap on the shortcut and the checkmark will disappear.

Great fix, David! I have a question. My iPhone XR’s lockscreen locks and goes to black after about 5 seconds. Many people have the same problem and have asked how to keep the lockscreen on longer but all the responses online suggest that changing the auto-lock time is the fix, but it’s not! (I know how to do it, but even putting the lockscreen setting on “Never” doesn’t stop my lockscreen from locking and sleeping after 5 seconds). I’ve also changed the setting and restarted my phone, but that didn’t help. I am running iOS 15.6 and was wondering if… Read more »
