What You Will Find on the Outside of Your iPhone X

By Edward C. Baig, Bob LeVitus

The iPhone X is a harmonious combination of hardware and software. But, it doesn’t look like past iPhones. Let’s take a brief look at what’s on the outside.

On the top and sides

The top edge of the iPhone X is as smooth as a baby’s bottom. The SIM card tray is on one side; the ring/silent switch and volume buttons are on the other. Here’s more about what these items do:

  • SIM card tray: The SIM card tray is where you remove or replace the SIM card inside your iPhone.

    A SIM (Subscriber Identity Module) card is a removable smart card used to identify mobile phones. Users can change phones by moving the SIM card from one phone to another — kind of. The iPhone uses a nano-SIM.

  • Side 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.

    Silent mode is overridden, however, by alarms you set in the built-in Clock app, music, audiobooks, and other purposeful audio, and selecting sounds such as ringtones and alert sounds in the Settings app.

    If your phone is set to ring mode and you want to silence it quickly, press the side button or press one of the volume buttons.

  • Volume up/down 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.

On the bottom of the iPhone X

On the bottom of your iPhone X, you find a microphone, the Lightning connector, and two of your four speakers:

  • Microphones: The microphone lets callers hear your voice when you’re not using a headset.

    The iPhone sports three microphones (top front, top back, and bottom). The top 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: You can use the Lightning connector 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.
    • 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.
    • 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.
    • Connect EarPods (or the included 3.5 mm headphone jack adapter and your favorite headset), 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 your iPhone 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 — if no headset is plugged in. They also play the ringtone you hear when you receive a call. Your iPhone X has four speakers.

On the front and back of the iPhone X

On the front of your iPhone X, you find the following:

  • Microphone: Used for FaceTime calls and noise suppression during phone calls.
  • 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.

    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).

  • TrueDepth camera: The camera on the front of the iPhone is tuned for Face ID and 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.
  • Status bar: The status bar displays important information, as you discover in a page or two.
  • Touchscreen: The iPhone has a gorgeous high-resolution color touchscreen. Try not to drool all over it.
  • 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 of your iPhone X, near the top-left corner, are two camera lenses, with the quad-LED True Tone flash between them.

The flash is used for still photos, as a floodlight for videos, and as a flashlight. (You can turn it on and off in Control Center.)

Finally, your iPhone has a third microphone on the back.
