FIGURE 1-1: Here’s what you’ll find on the sides of your iPhone.
Note that Figure 1-1 is an iPhone with Face ID, so although it does not have a Home button, all other buttons (and switches and trays) are shown in their proper locations.
On the bottom
On the bottom of your iPhone, you find a microphone, the Lightning connector, and the speakers, as shown in Figure 1-2:
Microphone: The microphone lets callers hear your voice when you’re not using a headset. The iPhone sports three microphones (front, back, and bottom). The front and back ones are used for FaceTime calls and also work with the main mic (located on the bottom) to suppress unwanted and distracting background sounds on phone calls using dual-mic noise suppression or beam-forming technology.
Lightning connector: The Lightning connector has three purposes: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, a USB port on your computer, or a port on a powered USB hub.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.You can use the Lightning 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.You use the Lightning port to connect EarPods (or your favorite headset, which may require a 3.5 mm 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.Little-known fact: The EarPods with Lightning connector that come with all iPhones before the iPhone 12 will work with any iOS device with a Lightning connector.
Speakers: The speakers are used by the iPhone’s built-in speakerphone and for playing audio — music or video soundtracks — when no headset is connected. They also play the ringtone you hear when you receive a call. All current iPhones have stereo speakers.
FIGURE 1-2: All current iPhone models, as seen from the bottom.
On the front
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/front microphone: The receiver (speaker) and front mic that the iPhone uses for telephone calls. The receiver naturally sits close to your ear whenever you hold your iPhone in the “talking on the phone” position; the mic is used for noise-cancelling and FaceTime calls. You should be the only one who hears sound coming from the receiver. If you have the volume set above about 50 percent and you’re in a location with little or no background noise, someone standing nearby may be able to hear the sound, too. So be careful. If you require privacy during phone calls, use the included Apple headset (or any compatible third-party wired or wireless headset — as discussed in Chapter 14).
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 2. All we have to say at this time is try not to drool all over it.
Home button and Touch ID sensor (Touch ID models): No matter what you’re doing, you can press the Home button at any time to display the Home screen, which is the screen shown in Figure 1-3. The iPhone’s Touch ID sensor can use your fingerprint to unlock the phone (see Chapter 2).
App icons: Each icon on the (first) Home screen launches an included iPhone app or one you’ve acquired from the App Store.

On the back
On the back of your iPhone are one to three camera lenses that look like little circles or ovals in the top-left corner. The iPhone also has one or more little LEDs next to the camera lens for use as a flash for still photos, as a floodlight for videos, and as a flashlight (turn it on and off in Control Center). For more on using the camera and shooting videos, see Chapters 9 and 10, respectively; for more on the flashlight and Control Center, see Chapter 5.
Finally, all current iPhone models have a third microphone on the back used primarily for noise cancelling.
Status bar
The status bar, which is at the top of every Home screen and displayed by many (if not most) apps, displays tiny icons that provide a variety of information about the current state of your iPhone:
Cell signal: The strength of the cellular signal. The cell signal icon tells you whether you’re within range of your wireless telephone carrier’s cellular network and therefore can make and receive calls. The more filled circles you see (five is the highest), the stronger the cellular signal. If you’re out of range, the circles are replaced with the words No Service. And if your iPhone is looking for a cellular signal, the circles are replaced with Searching.If your screen shows only one or two filled circles, try moving around a little bit. Even walking a few feet can sometimes mean the difference between no service and three or four filled circles.
Airplane mode: All wireless features of your iPhone — the cellular, 5G, 4G, 3G, GPRS (General Packet Radio Service), and EDGE networks, Wi-Fi, and Bluetooth — are turned off. You’re allowed to use your iPod on a plane after the captain gives the word. But you can’t use your cellphone except when the plane is in the gate area before takeoff or after landing. Fortunately, your iPhone offers an airplane mode, which turns off all wireless features of your iPhone and makes it possible to enjoy music or video during your flight. Some flights now offer on-board Wi-Fi. If you’re on such a flight, you can turn on Wi-Fi even when airplane mode is enabled. Just don’t turn it on until the captain says it’s okay.
LTE: Your wireless carrier’s high-speed LTE network is available.
5GE: Your wireless carrier’s 5GE network is available.
4G: Your wireless carrier’s high-speed UMTS network is available.
