How To Use iPhone 12 Pro Max in The Best Way? Setup & Guide

How to use iPhone 12 Pro Max.

Congratulations! You’re now the proud owner of a new iPhone 12 mini, iPhone 12, iPhone 12 Pro, or iPhone 12 Pro Max. You probably want to dive right into the phone the moment you get the box in your hands, but try to contain your excitement and do a little prep first!

We have a little setup advice you’re going to want to pay attention to. Sure, it seems like an unnecessary drag, but this stuff is going to really save you a lot of time and frustration later.

While you wait for backups and updates, check out our guide to iOS 14 to get up to speed with the latest iPhone operating system.

Updated 03/17/21: Added links to all our iPhone 12 reviews, as well as our iOS 14 guide.

1. Back up and restore

That’s right, you’re going to want to back up your old iPhone after you have your new iPhone 12 in hand, so the backup is as up-to-date as it can possibly be. You can back up via iCloud, in iTunes, or in the Finder.

For a Mac backup (macOS Catalina): Connect your old iPhone to your Mac, open a new Finder window, and select your iPhone in the left column in the Locations section. You’ll see a window that looks like the iPhone management window that used to be in iTunes. In the Backups section, choose, Back up all of the data on your iPhone to this Mac. Checking Encrypt local backup is a good idea, so your account passwords and Health data gets backed up too—just choose a password you won’t forget. Click the button to Back up now.

In macOS Catalina, you can access your iPhone through the Finder.

When the backup is done, connect your new iPhone 12, then tell your Mac you want to restore from the backup you just made. Later, you can switch back to iCloud backups if you prefer, in Settings > iCloud > Backup. But it never hurts to run a backup on your own Mac every now and then. 

For a Mac backup (macOS Mojave or older): The backup process is similar to that described above for Catalina, but instead, you use the iTunes app. After you back up your old iPhone, connect your new one. iTunes will take you through the steps for set up.

Use iTunes if you’re using a Mac with an operating system older than macOS Catalina.

For an iCloud backup: No need to connect your old iPhone to your Mac. Just launch Settings and tap on your Apple ID profile listing at the top, then go to iCloud > iCloud Backup and select Back up now.

When setting up your new iPhone 12, you can restore your iPhone from this backup once you’ve logged into your new device with your Apple ID.

If you happen to be coming from an Android phone (hey, welcome to the garden!), there’s an Android Move to iOS app that can assist you with getting all of your your Google account data in Mail, Calendars, and Contacts, moving your camera roll over, even transferring your Chrome bookmarks to Safari.

2. Update your old iPhone, then use Quick Start

iOS has a feature called Quick Start. It’s practically magic. You just hold your new phone next to your old phone, and a little card pops up asking if you want to transfer all your stuff to the new device. You’ll then point your old phone’s camera at your new phone (which displays a cloud of little dots) and enter your old phone’s 6-digit passcode.

Quick Start

You’ll go through the rest of the setup process, like enabling Face ID, and then your phone will be ready to go, set up just like your old iPhone. It’ll even prompt you to update your old iPhone’s backup if it hasn’t been backed up in awhile. 

Setting up your phone this way transfers over most of your settings, the arrangement of your home screen, and more. It’s a huge time saver. But it requires iOS 11 or newer, so if for some reason you’ve gone years without updating your iPhone to at least iOS 11 (or to the current version, iOS 14) for some reason, you might want to update right away. You don’t want to have to wait through a big update process once you have your iPhone 12 in hand.

After you finish setting up your phone this way, you’ll want to give it a little while to re-download all your apps. Initially, your phone will show placeholders for your apps, all arranged and stuffed into folders exactly as on your old iPhone. But your new phone has to actually re-download apps, because every time you download an app from the App Store, your phone actually grabs a unique version specifically optimized for that iPhone model. But your user data and settings get transferred over, and that’s the important part.

As fast and easy as this is, we still recommend backing up your phone as described in number 1 above. If anything goes really wrong during your setup process, you’ll be glad you did!

3. Set up Face ID and Apple Pay

Yes, you should use Face ID for maximum security—it’s the quickest way to unlock your iPhone 12, and will make it less painful to use a complicated passcode, since you don’t have to type it in every time. Setting up Face ID is much faster than Touch ID, too—the setup screen will prompt you and ask you to slowly look around in a circle a couple times. It’s a lot quicker than tapping the home button dozens of times to register a fingerprint.

face id setup How to use iPhone 12 Pro Max in the best way? Setup & Guide


Setting up Face ID is a lot faster than Touch ID.

Worried about your privacy with Face ID? Don’t be. No photos of your face nor any other biometric data ever leave your phone—Apple doesn’t get any of that. And it isn’t accessible by other apps, just as other apps weren’t able to access your fingerprints with Touch ID. You can read all about it in our Face ID FAQ.

Since you need to have Face ID enabled in order to use Apple Pay, this would be a good time to jump into Apple’s Wallet app to set that up. If you’re new to Apple Pay, just follow the instructions within Wallet to add a credit card or two. If you already had Apple Pay on your old iPhone, you’ll notice that your credit cards have disappeared on your new iPhone. Why? For your security, of course. Your Wallet history will still be there, but you’ll have to re-enter any payment cards you’d like to use with Apple Pay. (For more on Apple Pay, check out our complete guide.) 

4. Update your apps

Great, now you should be on your home screen on your new iPhone, at last. Hit up the App Store first—you’ll want the latest versions of all of your apps. To check for app updates, launch the App Store app, then tap your account icon in the upper right. You’ll find an updates section beneath all your account info, and you can get the updates here. If you used Quick Setup, most of your apps should be up to date already, so this will be, er, quick.

Don’t forget you can have your apps auto-update by flipping the Updates switch in Settings > App Store > App Updates. Or, you can manually update your apps and just check out the “What’s New” release notes to see what changed. 

5. Pair your Apple Watch

If you use an Apple Watch (or maybe you just bought a brand new Apple Watch to go with your new phone) you’ll need to pair it to your new iPhone to keep the Activity data flowing to your Health database, and keep your new phone’s notifications flowing to your watch. First you have to unpair your watch from your old iPhone, either in the Apple Watch app on your old iPhone (tap your watch, then the “i” icon, then Unpair Apple Watch, then enter your iCloud password when prompted), or on the watch itself (Settings > General > Reset).

Then, launch the Watch app on your new iPhone 12, which will walk you through the pairing process including setting a passcode, unlocking behavior, and Apple Pay.

If your Apple Watch isn’t already running watchOS 7, you’ll want to update it. To upgrade, your Apple Watch needs to be connected to its charger, in range of your iPhone, and at least 50 percent charged. Then look for the Software Update option in the iPhone Watch app. Updating your Apple Watch can be a slow process, so it’s a good idea to get started early.

6. Learn the new gestures and commands

As you may have noticed, your iPhone 12 has no home button. Where the Home button used to be, you now have an extra half-inch or so of glorious OLED display!

If you’re coming from an iPhone X, XS, or 11, it will be totally familiar, of course. But if you’re upgrading from an older iPhone or an iPhone SE, you’ve got some new gestures to learn.

Here are a few basic commands you’ll need to re-learn now that your iPhone is “home free.”

  • Return Home:  Just swipe up from the bottom of the screen. Easy!

Jump between apps: Swipe left or right along the bottom edge of the phone to jump back and forth between apps. You can sort of “flick” from the bottom corners, moving your finger up and over, to “bounce” between the apps, or just slide directly side-to-side along the bottom edge.

App switcher: Swipe up from the bottom edge and pause for a second with your finger still on the display. App cards will quickly pop up, and you can lift your finger off and swipe around through them.

  • Close an app: If you need to kill an app from the app switcher, simply swipe up on it.
  • Take a screenshot: Simply press the side button and the volume up button at the same time.

There are lots of other new commands and gestures to learn. You’re in luck: We have a guide for that!

7. Charge it up, quick!

There’s a reason your new iPhone 12 has that shiny glass back, and that’s not because it’s a throwback to the iPhone 4. No, that glass back is for wireless charging support. To use this feature, you’ll need a compatible wireless charging pad that utilizes the Qi standard (we’ve tested a bunch, and here are some of our favorites). If you have one of those laying around, all you have to do is set your iPhone onto the pad and watch it start to power up. Say goodbye to the jumble of Lightning cables on your bedside table!

With iPhone 12, Apple has introduced a new feature called MagSafe. It’s a new magnetically-attached charging puck that is similar to other Qi wireless chargers, only with secure magnetic alignment. The precise alignment and new internal circuitry allows Apple to ramp up the charging speed all the way to 15 watts—twice as fast as it can go with regular Qi chargers and nearly as fast as a Lightning cable.

Of course, you can charge your iPhone 12 via Lightning if you want to. In fact, this is still the fastest way to charge your phone, provided you use the right power adapter and cable. The iPhone 12 supports fast charging using the USB-C Power Delivery (USB-PD) standard. Anything over 15 watts will charge your iPhone quite rapidly.

8. Make your Memoji

Animoji are cool, but Memoji takes them to the next level. If you’re upgrading from an iPhone X or iPhone 11, you may have already created a Memoji. If the iPhone 12 is your first iPhone with a the TrueDepth front camera system, it’s your first opportunity to build your cartoon avatar.

If the iPhone 12 is your first TrueDepth camera-enabled iPhone, it’s time to make your Memoji!

Start by opening the Messages app, and then stating a new message or opening an existing thread. Tap the Animoji icon along the bottom, and then the + sign at the beginning of the Animoji list.

We have a step-by-step Memoji guide to walk you through the process. 

9. Set up your Medical ID

Have you ever set up Medical ID on your iPhone before? If not, this is a potentially life-saving feature you should probably not overlook.

Your Medical ID info is accessible from the lock screen.

We have a quick and easy guide to setting up your Medical ID info, which emergency responders can access even while your phone is locked. 

10. Check out Apple’s User Guide

Did you know Apple maintains a very detailed (hundreds of pages!) user guide that tells you everything you need to know about your iPhone 12 hardware and the latest version of iOS?

iphone user guide


The iPhone User Guide is an awesome web resource, but you can also download the whole thing in the Books app for free.

You can access the iPhone User Guide on the web, either browse or search for what you want to know. It’s a good site to bookmark. You may instead want to download the free iBook version in the Books app. When you need help, you may not be in a place where you have easy internet access.

Even if you’ve been using iPhones for years, you’re sure to find some new trick of feature in Apple’s official guide. Browsing around in it is a great way to learn more about what your new iPhone 12 can do.

I have written professionally about technology for my entire adult professional life - over 20 years. I like to figure out how complicated technology works and explain it in a way anyone can understand.

iPhone 12 Pro Max Setup & Guide

1. Clean up all the apps cluttering your home screen

The App Library organizes all of your apps for you.

The App Library organizes all of your apps for you.

A new App Library feature in iOS 14 helps get rid of all of the apps that clutter your home screen. Instead of seeing all of them, you can hide a bunch off in a side panel that you can search as needed. That means you'll have more room for widgets. (More on widgets in a bit.)

Here's how to set up App Library:

Make sure App Library is turned on. To do that:

  • Open Settings.
  • Tap Home Screen.
  • Check "App Library Only."

Next, you can turn off the pages all of your apps appear on.

To do that:

  • Tap and hold on the home screen.
  • Tap the gray bar at the bottom of the screen.
  • Uncheck the circles for all of your home screens with apps on them.

Now, the App Library will automatically store all of your apps to the right of your primary home screen.

2. Have fun with widgets

Widgets are little boxes that appear on your home screen and show you more information about an app. For example, you can see some of your most recent playlists or podcasts on Spotify and jump right into it again. Or you can see how far along your Apple Watch Fitness rings are, see highlight photos from Apple photos and more.

Most of Apple's apps have widgets, as do many major third-party apps, like Google. More apps are adding support all the time, so check your widgets menu regularly to see if your favorite app added support.

You can add widgets to your home screen by pressing and holding anywhere until the app icons start wobbling, then tap the + button on the top left. Tap an app and select a widget size and it'll appear right on your home screen.

3. How to turn 5G on and off (iPhone 12 models only)

The iPhone 12, by default, will save battery by switching between 5G and 4G LTE as needed.

The iPhone 12, by default, will save battery by switching between 5G and 4G LTE as needed.

Apple's new iPhone 12 models automatically switch between 5G and older 4G LTE networks to save battery life. But, sometimes the iPhone 12 will connect to a 5G network even if your existing 4G LTE network is faster. You may also want to stay on 4G LTE just to save battery life. You can toggle between 4G and 5G by doing this:

  • Open Settings.
  • Tap Cellular.
  • Choose "Cellular Data Options."
  • Pick "Voice and Data"
  • Choose from "5G Auto" (which automatically switches between 4G and 5G, depending on what you're doing on your phone), "5G On" (which keeps 5G on all the time) or "LTE" (which keeps 4G on all the time).

Pro tip: Use the SpeedTest app to see which network is fastest where you live.

4. Charge faster

Apple's 20-watt iPhone charger.

The new iPhone 12 models don't come with a charging brick that you plug into the wall. And your iPhone won't charge as fast as possible if you use the old, small 5-watt Apple charger that you might still have around the house from older Apple gadgets. You need to buy an 18-watt charger (or faster) if you want to be able to charge your iPhone 12 up to 50% in 30 minutes. I recommend Apple's $19 20-watt iPhone plug or Anker's similarly priced charging brick. 

5. Picture in picture

Using picture-in-picture on an iPhone running iOS 14

This feature is fun. If you want to watch movies or TV shows from Netflix, Apple TV+ or other services, you can use a new feature called picture-in-picture. It's been around on the iPad and on Macs for a long time, but it's finally on the iPhone.

It lets you watch shows in a tiny box while you use other apps. It works with a bunch of apps including Netflix, HBO Max, Hulu and Apple TV.

Here's what you do:

  • Open the app you want to use, such as Netflix.
  • Start playing a movie or TV show.
  • Swipe up from the bottom screen after it starts playing, as if you're closing the app.
  • The video will start playing in a small window on your screen.
  • You can resize the window by pinching or pulling it.
  • Tap the video again and select the resize button in the top-right to bring it back to full screen.

6. Group chats and threaded messaging

If you're like me, you may have a bunch of group chats with friends and family in iMessage. With iOS 14, you can pin those important group chats to the top of your messages list. It makes those chats easy to find whenever you want to jump back in. Just do this:

  • Open Messages on your iPhone.
  • Tap and hold a chat that you want to pin to the top of the screen.
  • Choose "Pin."

This also works with individual text message threads, not just groups. You can unpin a chat by tapping and holding one of them and choosing "Unpin."

Group chats also support threaded messaging, allowing you to reply to a specific comment in a chat. To do this, open a group chat, press and hold a message and choose "Reply."
