1. Getting Started with Your iPhone

Your iPhone is one of the most amazing handheld devices ever because of how well it is designed. It has only a few external features you need to understand. For most of the things you do, you just use your fingers on your iPhone’s screen (which just seems natural), and the iPhone’s consistent interface enables you to accomplish most tasks with similar steps.

• Cameras—One of the iPhone’s camera lenses is located on its backside near the top-left corner (the iPhone 7 Plus, 8 Plus, and X have two lenses there); the other is on the front at the top near the center of the phone. When you take photos or video, you can choose the cameras on either side. All iPhone models have a flash located near the camera on the backside. The iPhone 6s and later models also have a flash on the front that comes from the screen; for the 5s and SE, there is no flash when you use the camera on the front.

• Side button—Press this button (called the Sleep/Wake button on the 5s and SE and located on the top of the phone instead of on the side of those models) to lock the iPhone’s screen and put it to sleep. Press it again to wake the iPhone from Sleep mode. You also use this button to shut down the iPhone and to power it up. On the iPhone X, it has other uses, such as activating Siri when you hold it down for a couple of seconds.

• Mute switch—This switch determines whether the iPhone makes sounds, such as ringing when a call comes in or making the alert noise for notifications, such as for an event on a calendar. Slide it toward the front of the iPhone to hear sounds. Slide it toward the back of the iPhone to mute all sound. When muted, you see orange in the switch.

• Volume—Press the upper button to increase volume; press the lower button to decrease volume. These buttons are contextual; for example, when you are listening to music, they control the music’s volume, but when you aren’t, they control the ringer volume. When you are using the Camera app, pressing either button takes a photo.

• Lightning port—Use this port, located on the bottom side of the iPhone, to plug in the Lightning headphones (iPhone 7/7 Plus or later models) or connect it to a computer or power adapter using the included USB cable. There are also accessories that connect to this port. The Lightning port accepts Lightning plugs that are flat, thin, rectangular plugs. It doesn’t matter which side is up when you plug something into this port.

  The iPhone 7/7Plus and later models come with an adapter that enables you to plug devices that have a 3.5 mm plug (such as prior versions of the EarPods) into the Lightning port.

• Headphone jack (5s, SE, 6/6 Plus, and 6s/6s Plus)—This standard 3.5 mm jack can be used for headphones (such as the older EarPods) and powered speakers.

• Touch ID/Home button (all iOS 11 compatible models except the X)—This serves two functions.

  The Touch ID sensor recognizes your fingerprint, so you can simply touch it to unlock your iPhone, sign in to the iTunes Store, use Apple Pay, and enter your password in Touch ID-enabled apps. On the iPhone 7/7s and later models, it technically isn’t even a button, rather it is a sensor only (though it still works like a button because you press it).

  It also serves as the Home button. When the iPhone is asleep, press it to wake up the iPhone; press it again to unlock the iPhone (if you have Touch ID enabled, this also enters your passcode; if not, you have to manually enter the passcode to unlock the phone). When the iPhone is awake and unlocked, press this button to move to the all-important Home screens; press it twice quickly to open the App Switcher. Press and hold the Home button to activate Siri to speak to your iPhone. You can also configure it so you can use it to perform other actions, such as pressing it three times to open the Magnifier.

One of the most significant hardware changes that Apple made for the iPhone X was to remove the Touch ID/Home button. This enables the iPhone X to have a larger screen than similarly sized iPhone models, such as the 7 or 8. Gestures and different button combinations replace some of the functions of the Touch ID/Home button while Face ID replaces the Touch ID function of this button.

Almost all iPhone activities start at the Home screen, or Home screens, to be more accurate, because the Home screen consists of multiple pages. When your iPhone is unlocked and you are using an app, you get to the Home screen by pressing the Touch ID/Home button once (all models except iPhone X) or touching and swiping up from the bottom of the screen (iPhone X). You move to the Home screen automatically any time you restart your iPhone and unlock it. Along the bottom of the Home screen (or along the side on an iPhone Plus model when held horizontally) is the Dock, which is always visible on the Home screens. This gives you easy access to the icons it contains; up to four icons can be placed on this Dock. Above the Dock are apps that do all sorts of cool things. As you install apps, the number of icons on the Home screens increases. To manage these icons, you can organize the pages of the Home screens in any way you like, and you can place icons into folders to keep your Home screens tidy. At the top of the screen are status icons that provide you with important information, such as whether you are connected to a Wi-Fi network and the current charge of your iPhone’s battery.

• Tap—Briefly touch a finger to the iPhone’s screen and then lift your finger again. When you tap, you don’t need to apply pressure to the screen, simply touch your finger to it. For example, to open an app, you tap its icon.

• Double-tap—Tap twice. You double-tap to zoom in on something; for example, you can double-tap on a web page to view something at a larger size.

• Swipe—Touch the screen at any location and slide your finger (you don’t need to apply pressure, just touching the screen is enough). You use the swipe motion in many places, such as to browse a list of options or to move among Home page screens. Whatever you are swiping on moves in the direction that you swipe.

  

• Drag—Touch and hold an object and move your finger across the screen without lifting it up; the faster you move your finger, the faster the resulting action happens. (Again, you don’t need to apply pressure, just make contact.) For example, you can drag icons around the Home screens to rearrange them.

  

• Pinch or unpinch—Place two fingers on the screen and drag them together or move them apart; the faster and more you pinch or unpinch, the “more” the action happens (such as a zoom in). When you are viewing photos, you can unpinch to zoom in on them or pinch to zoom out again.

  
  

• Rotate—Rotate the iPhone to change the screen’s orientation.

  
  

• Peek—On an iPhone that supports 3D Touch (iPhone 6s and later models), you can take action on something by applying pressure to the screen when you touch it. When you are looking at a preview of something, such as an email, touch and put a small amount of pressure on the screen to perform a Peek. A Peek causes a window to open that shows a preview of the object. You can preview the object in the Peek window; if you swipe up on a Peek, you get a menu of commands related to the object. For example, when you perform a Peek on an email and then swipe up on the Peek, you can tap Reply to reply to the email.

  
  

• Pop—When you are looking at a Peek, apply slightly more pressure on the screen to perform a Pop, which opens the object in its app. For example, you can perform a Peek on a photo’s thumbnail to preview it. Apply a bit more pressure (a Pop) on the preview to “pop” it open in the Photos app (for example, to crop your finger out of the photo).

One of the best things about an iPhone is that it can run all sorts of applications, or in iPhone lingo, apps. It includes a number of preinstalled apps, such as Mail, Safari, and so on, but you can download and use thousands of other apps, many of which are free, through the App Store. You learn about many of the iPhone’s preinstalled apps as you read through this book. And as you learned earlier, to launch an app, you simply tap its icon. The app opens and fills the iPhone’s screen. You can then use the app to do whatever it does.

On an iPhone that supports 3D Touch (iPhone 6s and later models), you can press on an app’s icon to open its Quick Actions menu; tap an action to take it. For example, when you open the Quick Actions menu for the Phone app, you can place calls to people you have designated as favorites.

In Chapter 5, “Customizing How Your iPhone Looks and Sounds,” you learn how you can organize icons in folders to keep your Home screens tidy and make getting to icons faster and easier. To access an icon that is in a folder, tap the folder. It opens and takes over the screen. Under its name is a box showing the apps it contains. Like the Home screens, folders can have multiple pages. To move between a folder’s pages, swipe to the left to move to the next screen or to the right to move to the previous one. Each time you “flip” a page, you see another set of icons. You can close a folder without opening an app by tapping outside its borders or by pressing the Touch ID/Home button (except the iPhone X).

To open an app within a folder, tap its icon.

When you are done using an app, press the Touch ID/Home button (all models except the iPhone X) or swipe up from the bottom of the screen (iPhone X). You return to the Home screen you were most recently using.

When you move out of an app by pressing the Touch ID/Home button or swiping up from the bottom of the screen (iPhone X only), the app moves into the background but doesn’t stop running (you can control whether or not apps are allowed to work in the background using the Settings app, which you use throughout this book). So, if the app has a task to complete, such as uploading photos or playing audio, it continues to work behind the scenes. In some cases, most notably games, the app becomes suspended at the point you move it into the background by switching to a different app or moving to a Home screen. In addition to the benefit of completing tasks when you move into another app, the iPhone’s capability to multitask means that you can run multiple apps at the same time. For example, you can run an Internet radio app to listen to music while you switch over to the Mail app to work on your email.

You can control apps by using the App Switcher. To see this, quickly press the Touch ID/Home button twice (all models except the iPhone X) or swipe up from the bottom of the screen and pause near the middle of the screen (iPhone X). The App Switcher appears.

At the top of the App Switcher, you see icons for apps you are currently using or have used recently. Under each app’s icon, you see a thumbnail of that app’s screen. You can swipe to the left or right to move among the apps you see. You can tap an app’s screen to move into it. That app takes over the screen, and you can work with it, picking up right where you left off the last time you used it.

When you open the App Switcher, the app you were using most recently comes to the center to make it easy to return to. This enables you to toggle between two apps easily. For example, suppose you need to enter a confirmation number from one app into another app. Open the app into which you want to enter the number. Then open the app containing the number you need to enter. Open the App Switcher and tap the previous app to return to it quickly so that you can enter the number.

To close the App Switcher without moving into a different app, press the Touch ID/Home button once (all models except iPhone X) or tap outside the App Switcher (iPhone X). You move back into the app or Home screen you were most recently using.

In some cases, you might want to force an app to quit, such as when it’s using up your battery too quickly or it has stopped responding to you. To do this, open the App Switcher. Swipe up on the app you want to stop. The app is forced to quit, its icon and screen disappear, and you remain in the App Switcher. You should be careful about this, though, because if the app has unsaved data, that data is lost when you force the app to quit. The app is not deleted from the iPhone—it is just shut down until you open it again (which you can do by returning to the Home screen and tapping the app’s icon).

Sometimes, a link in one app takes you into a different app. When this happens, you see a left-facing arrow with the name of the app you were using in the upper-left corner of the screen. You can tap this to return to the app you came from. For example, you can tap a link in a Mail email message to open the associated web page in Safari. To return to the email you were reading in the Mail app, tap the Mail icon in the upper-left corner of the screen.

Apps can provide widgets, which make it easy to work with those apps from the Widget Center. To access these widgets, swipe all the way to the right from a Home screen or from the Lock screen (more on this later). You see widgets for various apps. Swipe up or down the screen to browse all the widgets available to you. Tap Show Less to collapse a widget or tap Show More to expand it. Tap something inside a widget to use that app. For example, tapping an album in the Music widget plays it. You learn more about how to use widgets in Chapter 2, “Using Your iPhone’s Core Features” and how to configure the Widget Center in Chapter 4, “Customizing How Your iPhone Works.”

The Home screen has multiple pages. To change the page you are viewing, swipe to the left to move to later pages or to the right to move to earlier pages. The dots above the Dock represent the pages of the Home screen; the white dot represents the page being displayed. You can also change the page by tapping to the left of the white dot to move to the previous page or to the right of it to move to the next page.

When you hold an iPhone Plus in the horizontal orientation, you can take advantage of the Split-screen feature in many apps (not all apps support this). In Split-screen mode, the screen has two panes. The left pane is for navigation, whereas the right pane shows the content selected in the left pane. The two panes are independent, so you can swipe up and down on one side without affecting the other. In most apps that support this functionality, there is an icon you can use to open or close the split screen. This icon changes depending on the app you are using. For example, when you are using Safari to browse the Web, tap the Bookmark icon to open the left pane and tap it again to close the left pane (while the left pane is open, you can select bookmarks and see the associated web pages in the right pane). As another example, in the Mail app, you tap the Full Screen icon (two arrows pointing diagonally away from each other) to open or close the left pane.

Preinstalled apps that support this functionality include Settings, Mail, Safari, and Messages; you see examples showing how Split-screen works in those apps later in this book. You should hold your iPhone Plus horizontally when using your favorite apps to see if they support this feature.

When you hold an iPhone Plus horizontally and move to the Home screen, the Dock moves to the right side of the screen and you see the Home screen’s pages in the left part of the window. Though this looks a bit different, it works the same as when you hold an iPhone vertically.

The Control Center provides quick access to a number of very useful controls. To access it, swipe up from the bottom of the Home screen (all models except the iPhone X) or swipe down from the upper-right corner of the screen (iPhone X). If your iPhone is asleep/locked, press the Side or Touch ID/Home button or lift the phone to wake it up and then swipe up from the bottom of the Home screen (all models except the iPhone X) or swipe down from the upper-right corner of the screen (iPhone X). When the Control Center opens, you have easy and quick access to a number of controls.

In the top-left quadrant of the Control Center are icons you can use to turn on or turn off important functions, which are Airplane mode, Cellular Data, Wi-Fi, Bluetooth, Orientation Lock, and Do Not Disturb mode. To activate a function, tap its icon, which changes color to show the function is active. To disable a function, tap the icon so that it becomes gray to show you it is inactive. For example, to lock the orientation of the iPhone’s screen in its current position, tap the Orientation Lock icon so it becomes red. Your iPhone screen’s orientation no longer changes when you rotate the phone. To make the orientation change when you rotate the phone again, tap the Orientation Lock icon to turn it off again. You learn about the Airplane and Do Not Disturb modes later in this chapter. Wi-Fi and Cellular Data are explained in Chapter 2. You learn about using Bluetooth in the online Chapter 15, “Working with Other Useful iPhone Apps and Features.”

In the upper-right quadrant, you see the Audio Player. You can use this to control music, podcasts, and other types of audio that are playing in their respective apps (you learn about the Music app in the online Chapter 15).

Just below the Audio Player are the Brightness and Volume sliders. You swipe up or down on these to increase or decrease the screen’s brightness and the volume of whatever you are hearing on your phone.

The controls above the first row of four icons are always on the Control Center; you can’t change them in any way. However, below those are a section of controls you can change. By default, you see the Flashlight, Clock, Calculator, Camera, and others in this area. Like the icons toward the top of the screen, tap these icons to perform the associated action, such as using the iPhone’s flash as a flashlight, or opening an app—the Clock app, for example. You can configure the controls that are in this area by adding, removing, and organizing them; you learn how to configure your Control Center in Chapter 4.

When you press on some of the controls, such as the Brightness slider, you see additional options. You should press the controls you use to see what options are available. For example, when you press the Brightness slider, you see a larger slider and have access to the Night Shift icon (you learn about Night Shift in Chapter 5).

When you’re done using the Control Center, tap the downward-facing arrow at the top of the screen and the Control Center is hidden.

Examples of using the controls on the Control Center are throughout the rest of this book.

Individual notifications (onscreen alerts, sounds, or vibrations) arrive with the events with which they are associated such as new emails, messages, and updated information from apps. For example, you can have banner notifications and a sound when you receive new text messages.

You learn how to work with the notifications your iPhone uses in Chapter 2. Because there is likely to be a lot of activity on your iPhone, you want to customize the notifications you receive so you are aware of important information but not distracted or annoyed by less important activity; configuring notifications is explained in Chapter 4.

You can also access groups of notifications on the Notification Center, which you open by swiping down from the top of the screen when your iPhone is unlocked or swiping up from the middle of the screen when it is locked. The Notification Center opens and displays notifications grouped by day and the app from which they come. You can read the notifications by swiping up and down the screen. You can work with the notifications on the Notification Center just as you work with individual notifications (see Chapter 2). For example, on an iPhone with 3D Touch, press on a notification to pop it open to read more of it or to take action on it; press a little harder to open the associated app. On iPhones without 3D Touch, tap a notification to move into the associated app.

When you swipe to the left on a notification, you can tap Clear to delete the notification or View to open it. If you swipe to the right on a notification, you open the app that generated it (if your iPhone is locked, you need to unlock it to move into the app). If you press on a notification, it opens in a window that enables you to read the notification, such as an email, and take action on it.

You can remove all the notifications for a day by tapping its Delete (x) icon and then tapping Clear.

To close the Notification Center when your iPhone is unlocked, move back to the Home screen (press the Touch ID/Home button except on the iPhone X where you swipe up from the bottom of the screen). When the iPhone is locked, just press the Side button to put the phone to sleep to hide the Notification Center.

Earlier, you learned how to access apps from the Home page and App Switcher. Your iPhone can make recommendations about apps that you might want to use based on those you have most recently used, your current activity, and even your location. You can see these suggestions by swiping down from about ¾ up the screen (if you swipe down from the top, you open the Notification Center instead). In the SIRI APP SUGGESTIONS panel, you see the apps being suggested. Tap an app to open it. You can show more apps by tapping Show More, or if the panel is already expanded, tap Show Less to show fewer apps.

At the top of the screen is the Search bar, which you can use to search your phone (this is covered in Chapter 2).

In the SIRI SEARCH SUGGESTIONS panel, you can tap a suggested search to run it (this is also covered in Chapter 2).

If you don’t want to use any of the apps shown or perform a search, tap Cancel to return to the previous screen.

To put your iPhone in Do Not Disturb mode, open the Control Center and tap the Do Not Disturb icon. It becomes purple and the Do Not Disturb: On status appears at the top of the Control Center. Your iPhone stops notifications. The Do Not Disturb status icon appears at the top of the Home screens so you know your iPhone is silent.

To make your notifications active again, tap the Do Not Disturb icon so it is gray; your iPhone resumes trying to get your attention when it is needed, and the Do Not Disturb status icon disappears from the top of the Home screens.

In Chapter 4, you learn how to set a schedule for Do Not Disturb so that your iPhone goes into this mode automatically at certain times, such as from 10 p.m. to 6 a.m. You can also configure certain exceptions, including whose calls come in even when your iPhone is in Do Not Disturb mode.

To put your iPhone in Airplane mode, open the Control Center and tap the Airplane mode icon. All connections to the cellular network stop, and your iPhone doesn’t broadcast or receive any cellular signals. The Airplane mode icon becomes orange, and you see the Airplane mode status icon at the top of the screen.

In Airplane mode, you can use apps that don’t require a cellular connection; for example, you can connect to a Wi-Fi network to work with email or browse the Web.

To turn off Airplane mode, open the Control Center and tap the Airplane mode icon; it becomes gray again and the Airplane mode status icon disappears. The iPhone resumes transmitting and receiving cellular signals, and all the functions that require a cellular connection start working again.

When you perform actions, Siri uses the related apps to accomplish what you’ve asked it to do. For example, when you create a meeting, Siri uses the Calendar app.

Siri is a great way to control your iPhone, especially when you are working in handsfree mode.

Your iPhone has to be connected to the Internet for Siri to work. That’s because the words you speak are sent over the Internet, transcribed into text, and then sent back to your iPhone. If your iPhone isn’t connected to the Internet, this can’t happen and Siri reports that it can’t connect to the network or simply that it can’t do what you ask right now.

Using Siri is pretty simple because it follows a consistent pattern and prompts you for input and direction.

Activate Siri by pressing and holding down the Touch ID/Home button (all models except iPhone X) or pressing and holding the Side button (iPhone X) until you hear the Siri chime. If so configured (see Chapter 11), you can say “Hey Siri” to activate it, too. And, if those ways aren’t enough, you can press and hold down the center part of the buttons on the right EarPod wire.

All of these actions put Siri in “listening” mode, and the “What can I help you with?” text appears on the screen (although when you use “Hey Siri” to activate it, the onscreen text is skipped and Siri gets right to work). This indicates Siri is ready for your command.

Speak your command or ask a question. When you stop speaking, Siri goes into processing mode. After Siri interprets what you’ve said, it provides two kinds of feedback to confirm what it heard: It displays what it heard on the screen and provides audible feedback to you. Siri then tries to do what it thinks you’ve asked and shows you what it is doing. If it needs more input from you, you’re prompted to provide it and Siri moves into “listening” mode automatically.

If Siri requests that you confirm what it is doing or make a selection, do so. Siri completes the action and displays what it has done; it also audibly confirms the result.

Siri isn’t quite like using the computer on the Starship Enterprise on Star Trek, but it’s pretty darn close. Mostly, you can just speak to Siri as you would talk to someone else, and it is able to do what you want or asks you the information it needs to do what you want.

You seldom need to turn your iPhone off, but when you do, press and hold the Side button until the slider appears at the top of the screen. (On an iPhone 5s or SE, use the Sleep/Wake button located on the topside of the phone to turn it off or on.) Swipe the slider to the right to shut down the iPhone. The iPhone shuts down.

To restart your iPhone, press and hold the Side button until the Apple logo appears on the screen, and then let go of the button.

After it starts up, assuming you have a passcode, you see the Enter Passcode screen. Enter your passcode to start using your phone; once your passcode is entered correctly, you move to the Home screen. (Even if you have Touch ID or Face ID enabled to unlock your phone, you must enter your passcode the first time you unlock it after a restart.)

If you don’t have a passcode configured (you should have a passcode configured to protect your information), you move directly to the Home screen when the phone starts and it’s ready for you to use. Keep in mind, if you do not have a passcode configured, your phone is vulnerable to anyone who gets hold of it. (See Chapter 5 for more information about configuring passcodes and Touch ID or the online supplement My iPhone X at informit.com/myiphoneseniors to learn how to work with Face ID.)

Also, when you put your iPhone to sleep, much of its functionality can’t be used until it is unlocked; you can do a number of tasks, such as using widgets and viewing notifications, while the iPhone is awake, but locked. If you configure your iPhone to require a passcode to unlock, this also protects your information. Even when the iPhone is asleep, you can receive and work with notifications, such as when you receive emails or text messages. (See Chapter 4 to configure which notifications you see on the Lock screen and how you can interact with them.)

To put your iPhone to sleep and lock it, press the Side button (on an iPhone 5s or SE, use the Sleep/Wake button). The screen goes dark.

When an iPhone is asleep/locked, you need to wake it up to use it. You can do this in several ways: touch or press the Touch ID/Home button, press the Side button (Sleep/Wake button on a 5s or SE) or simply raise the iPhone (on models that support the Raise to Wake feature). The Lock screen appears.

If you want to use app widgets (swipe to the right), access the Notification Center (swipe up from the middle of the screen), open the Control Center (swipe up from the bottom of the Home screen [all models except the iPhone X] or swipe down from the upper-right corner of the screen [iPhone X]), take photos or video (swipe to the left), or control audio playback (when audio is playing the controls appear on the Lock screen), you can do so directly on the Lock screen.

When you are ready to use apps or access your Home screens, you need to unlock your iPhone. How you unlock your iPhone depends on its state and the model you are using.

If you don’t have a passcode (you should have a passcode to protect your information on the phone), you can press the Touch ID/Home button (all models except iPhone X) or swipe up from the bottom of the screen (iPhone X) to unlock it.

If you have configured a passcode (see Chapter 4), which you should have on your phone, there are two states your iPhone can be in; how you unlock it depends on its state.

If you restarted your iPhone, you need to enter its passcode, even if you have Touch ID or Face ID configured to unlock it.

If you have an iPhone with Touch ID configured to unlock it (see Chapter 4), press the Touch ID/Home button with a finger whose fingerprint has been stored for use; if you are using an iPhone 7 or later model (except the iPhone X), you don’t need to press the Touch ID/Home button and can simply touch it instead. When your fingerprint is recognized, your iPhone unlocks and you can start using it.

If you have an iPhone X with Face ID configured to unlock it, you swipe up from the bottom of the screen and look at the screen. When the iPhone recognizes your face, the phone unlocks and you can use it.

If your iPhone doesn’t have Touch ID or Face ID configured to unlock it, press the Touch ID/Home button (all models except iPhone X) or swipe up from the bottom of the screen (iPhone X) and enter your passcode to unlock your phone.

However you unlock the phone, when it unlocks, you move to the last screen you were using before it was locked.

If you don’t use your iPhone for a while, it automatically goes to sleep and locks according to the preference you have set for it (this is covered in Chapter 5).

Once configured, using Touch ID is as simple as touching a recorded fingerprint to the Touch ID/Home button when you are prompted to do so. The resulting action is completed, such as downloading an app from the App Store. (As referenced in the prior note, you need to configure your iPhone to recognize your fingerprints to use Touch ID and to enable where it can be used; see Chapter 4 for details.)

Face ID works similarly except that instead of touching the Touch ID/Home button, you look at the screen. When the iPhone recognizes your face, the action is completed.

If you don’t have the settings configured to enable you to use Touch ID or Face ID or you use an app that doesn’t support Touch ID or Face ID, you need to provide your password when prompted to do so. Whatever action you were performing is completed.

To change the iPhone’s volume, press the up or down Volume button on the side of the iPhone. When you change the volume, your change affects the current activity. For example, if you are on a phone call, the call volume changes, or if you are listening to music, the music’s volume changes. If you aren’t on a screen that shows a Volume slider, an icon pops up to show you the relative volume you are setting and the type, such as setting the ringer’s volume. When the volume is right, release the Volume button.

You can also use the Volume slider on the Control Center to change the volume level.

When you are using an audio app, such as the Music app, you can also drag the volume slider in that app or on the Control Center to increase or decrease the volume. Drag the slider to the left to lower volume or to the right to increase it.

When you use the iPhone’s EarPods, you can change the volume by pressing the upper part of the switch on the right EarPod’s wire to increase volume or the lower part to decrease it.

To mute your phone’s sounds, slide the Mute switch, located on the left side of the phone, toward the back of the phone. You see an on-screen indicator that the phone is muted and you see orange within the Mute switch on the side of the iPhone; notification and other sounds won’t play. To restore normal sound, slide the switch toward the front of the phone.
