On the older iPhones with Touch ID you’d have to hold down both the Sleep/Wake button and the Home button. On the newer Face ID devices this can be a bit different.
You might notice if you try Volume + Sleep, that it wants to shut down or even call emergency services. So that’s not the way.
Okay, for the iPhone 11 Pro Max, follow these steps.
- Press Volume-Up button once.
- Press Volume-Down button once.
- Press and hold the Sleep/Wake button, and keep holding until you see the Apple logo appear.
This should work on all iPhone X and iPhone 11 devices by the way.
When do you need this? Almost never. The iPhone 11 doesn’t require a shutdown, restart, etc. The iOS upgrades will take care of everything. You can use App Switcher to shutdown apps as well. Maintenance to phone is; Turn it on, use it, don’t worry about shutting it down and all that.
But every once in a while if some glitchy behavior shows up on-line articles might recommend to at least try a force restart. And then this is how you do that. Up/Down, and then hold Sleep until Apple logo.
The official method recommended by Apple is to hold the Sleep-button and swipe the Shutdown and let it shut down. Then hold Sleep until the Apple logo shows up. But what if your screen isn’t even responsive anymore? And in that case this trick works, because you’re literally only using hardware buttons to achieve a restart (and it’s actually quite a bit faster as well)
