iPhone 13 Pro Max screen freeze

Hi naydelin147,

Thanks for contacting Apple Support Communities!

We understand that your iPhone display stops responding and shuts down unexpectedly, correct?

Although we're unable to speculate as to what is causing it, we've included a couple articles below to help you to troubleshoot and isolate this behavior further because they relate to that specific issue with randomly restarting (even when powered off):

If your iOS or iPadOS device restarts or displays the Apple logo or a spinning gear unexpectedly

"If your iPhone, iPad, or iPod touch unexpectedly restarts or shuts down, or displays the Apple logo or a spinning gear, learn what to do.

Check your software

Make sure that your device has the latest version of iOS or iPadOS and that your apps are up to date. If the issue continues after updating your software and apps, check your hardware.

Check your hardware

On an iPhone 6 or later, check your battery health under Settings > Battery > Battery Health.

If your battery doesn't need service, and your iPhone, iPad, or iPod touch continues to frequently restart or turn off, contact Apple Support.

If your apps quit unexpectedly, learn what to do.

If your device has a frozen screen, doesn't respond, or becomes stuck when you turn it on, learn what to do for iPhone, iPad, or iPod touch."

"Check your network conditions

Many apps on your device require an internet connection for their content and other functionality. If the network that you're connected to is congested—for example, at an event with many people using the same network—apps might take a while to open or display their content. Your device can also seem slow as it repeatedly reconnects to new cell towers when you're in a moving vehicle.

Even if your device indicates a strong signal, you might need to wait, try again in a different location, or use available Wi-Fi. If you continue to experience issues with cellular data speed, availability, or performance in multiple locations, contact your carrier.

Learn more about cellular data.

Close an app that's not responding

If an app stops responding or freezes, you might need to force it to close and then open it again.*

1. From the Home screen of iPhone X or later or an iPad, swipe up from the bottom of the screen and pause slightly in the middle of the screen. On iPhone 8 or earlier, double-click the Home button to show your most recently used apps.
2. Swipe right or left to find the app that you want to close. 
3. Swipe up on the app's preview to close the app. 

* Under normal conditions, force closing apps is not necessary and does not make your device run faster. In fact, an app takes longer to open after a force close because it has to reload all of its data.

Learn what to do if an app repeatedly stops responding.

Make sure you have enough storage

If your device is low on storage, iOS or iPadOS automatically frees up space while installing an app, updating iOS or iPadOS, downloading music, recording videos, and more. iOS or iPadOS only removes items that can be downloaded again or that aren't needed anymore. 

You can check your device's storage in Settings > General > [Device] Storage. For best performance, try to maintain at least 1GB of free space. If your available storage is consistently less than 1GB, your device might slow down as iOS repeatedly makes room for more content.

If you need to free up some space, follow these steps to turn on the storage-saving recommendations built in to iOS or iPadOS:

1. Go to Settings > General > [Device] Storage and read the recommendations that iOS or iPadOS might provide.
2. Tap Enable to turn on a recommendation, or tap a recommendation title to review the content that you can delete.

If you don't see any recommendations—or if you need to free up even more space—you can review the apps on your device. They're listed on the same [Device] Storage screen along with the amount of space that they use.

Tap an app, then choose from the options:

• Offload the app, which frees up storage used by the app, but keeps its documents and data.
• Delete the app, which removes the app and its related data.
• Depending on the app, you might be able to delete some of its documents and data.

Leave Low Power Mode off when you don't need it

Low Power Mode is an iPhone and iPad feature that extends battery life by reducing the amount of power that your device uses. In Low Power Mode, some features are turned off and some tasks might take longer to complete. If your battery icon is yellow, that means Low Power Mode is on. 

Consider leaving Low Power Mode off if you need your iPhone or iPad to function without low-power restrictions. You can turn Low Power Mode on or off in Settings > Battery.

Get more information about Low Power Mode.

Keep your device from getting too hot or cold

iOS or iPadOS adjusts your device's performance if it's become too warm due to external conditions, like being left in a hot car or used for an extended time in direct sunlight. Move your device to a cooler location and let its temperature adjust. 

Very cold temperatures can also slow your device. If your device runs slowly after being exposed to cold, move it to a warmer location.

Learn more about acceptable operating temperatures.

Look at your battery health

All rechargeable batteries are consumable components that become less effective as they chemically age. Over time, the rechargeable batteries in all iPhone models will diminish in their capacity and peak performance and will eventually need to be replaced. iOS can show battery health and recommend if an iPhone battery needs to be replaced. Go to Settings > Battery and tap Battery Health. Battery Health is available only on iPhone.

Check your iPhone battery.

• A touch screen that responds to taps incorrectly can make your device seem slow. If you think that your touch screen isn't responding correctly, try restarting your iPhone, iPad, or iPod touch. If that doesn't work, and the issue occurs in the same area of the screen in multiple apps, you might need to contact Apple Support.
• If you tried these tips and your iPhone, iPad, or iPod touch is still slow or continues to freeze, contact Apple Support."

If you determine that your iPhone screen isn't responding to touch, this may help as well: If the screen isn't working on your iPhone or iPad

"If your screen is too sensitive or responds intermittently to touch

1. Restart your iPhone or iPad.
2. Make sure that your screen is clean and free of any debris or water.
3. Disconnect any Lightning or USB-C accessories. If your screen works after removing an accessory, try using a different outlet, cable, or charger.
4. Remove any cases or screen protectors.

Contact Apple Support

If your screen still isn't working, you might need to set up service for your device. Contact Apple Support."

We hope this helps.

Cheers!
