A Quick Tour Outside
The iPhone is a harmonious combination of hardware and software. In this section, we take a brief look at what’s on the outside. In the next section, we peek at the software.
The top of iPhone 6 and 7 models is as smooth as a baby’s bottom, as shown in Figure 1-1. If you have one of the iPhone 6 models, your sleep/wake button is on the side. For all models, the SIM card tray is on one side, and the ring/silent switch and volume buttons are on the other side. We describe these elements more fully in the following list:
❯❯ Microphone: Used for FaceTime calls and noise suppression during phone calls.
❯❯
SIM card tray: The SIM card tray is where you remove or replace the SIM card inside your iPhone.
❯❯ Sleep/wake button: This button is used to lock or unlock your iPhone and to turn your iPhone on or off. When your iPhone is locked, you can still receive calls and text messages, but nothing happens if you touch its screen. When your iPhone is turned off, all incoming calls go directly to voicemail.

Ring/silent switch: This switch, which is on the left side of your iPhone, lets you quickly swap ring mode and silent mode. When the switch is set to ring mode – the up position, with no orange showing on the switch – your iPhone plays all sounds through the speaker on the bottom. When the switch is set to silent mode – the down position, with orange visible on the switch – your iPhone doesn’t make a sound when you receive a call or when an alert pops up on the screen.
❯❯ Volume buttons: Two volume buttons are just below the ring/silent switch. The upper button increases the volume; the lower one decreases it. You use the volume buttons to raise or lower the loudness of the ringer, alerts, sound effects, songs, and movies. And during phone calls, the buttons adjust the voice loudness of the person you’re speaking with, regardless of whether you’re listening through the receiver, the speakerphone, or a headset.
FIGURE 1-1: The rear side of the iPhone SE (left), 6s (center), and 7 (right), as seen from the top.
On the bottom of your iPhone, you find a microphone, the Lightning connector, the speaker (or speakers), and the headset jack (all but iPhone 7 models), as shown in Figure 1-2:
❯❯ Headset jack (iPhone SE and 6): The headset jack lets you plug in the included iPhone headset, which looks a lot like EarPods but with an elliptical shape.
❯❯ Microphone: The microphone lets callers hear your voice when you’re not using a headset.
❯❯ Lightning connector: The Lightning connector has three purposes for most iPhones and four for iPhone 7 models. One, you can use it to recharge your iPhone’s battery. Simply connect one end of the included Lightning–connector–to–USB cable to the iPhone and the other end to the USB power adapter. Two, you can use the port to synchronize. Connect one end of the cable to the port on your iPhone and the other end to a USB port on your Mac or PC. Three, you can use the Lightning or dock connector port to connect your iPhone to other devices, such as a camera or television using an adapter such as the Camera Connection Kit or one of Apple’s A/V adapter cables. And four (iPhone 7 models only), you use it to connect EarPods or the included 3.5mm headphone jack adapter so you can listen to audio or talk on the phone without holding a slab of glass and metal in front of your face.
❯❯ Speaker: The speaker is used by the iPhone’s built-in speakerphone and plays audio – music or video soundtracks – if no headset is plugged in. It also plays the ringtone you hear when you receive a call. iPhone 7 models have stereo speakers.
FIGURE 1-2: The front side of the iPhone SE (left), 6s (center), and 7 (right), as seen from the bottom.
On the front of your iPhone, you find the following (labeled in Figure 1-3):
❯❯ Camera: The camera on the front of the iPhone is tuned for FaceTime, so it has just the right field of view and focal length to focus on your face at arm’s length, which presents you in the best possible light.
❯❯ Receiver: The receiver is the speaker that the iPhone uses for telephone calls. It naturally sits close to your ear whenever you hold your iPhone in the “talking on the phone” position.
❯❯ Status bar: The status bar displays important information, as you discover in a page or two.
❯❯ Touchscreen: You find out how to use the iPhone’s gorgeous high-resolution color touchscreen in Chapter
