iPhone All-in-One For Dummies. Hutsko Joe

To turn iPhone off: Press and hold the Sleep/Wake button until the bar appears with the message Slide to Power Off. Drag your finger from left to right across this bar to turn iPhone off. Tap the Cancel button at the bottom of the screen if you change your mind.

      ✔ To put iPhone to sleep: Press the Sleep/Wake button once.

      ✔ To wake iPhone: Press either the Sleep/Wake button or the Home button, which is the round button below the screen that we explain in a couple of paragraphs. Then do one of the following to reach the Home screen or the app you were using before your iPhone went to sleep:

      • Without passcode: Slide your finger across the Lock screen.

      • With passcode: Slide your finger across the Lock screen and then tap your passcode on the keypad that appears.

      • With Touch ID: Rest your finger on the Home key (without sliding your finger across the Lock screen).

      iPhone goes to sleep and locks (not to be confused with the SIM lock) automatically when you don’t touch the screen for one minute. You can change this setting to up to five minutes or never in the Settings app by tapping General and then tapping Auto-Lock. This saves battery power and keeps you from unintentionally opening an app or making a call by accidentally touching the Home screen. When iPhone is asleep or locked, you still receive phone calls, messages, and alerts – unless you have the Do Not Disturb function activated – and can listen to music. You can also adjust the volume of a call or music with the volume buttons on the side of the phone.

      Incoming communications such as a phone call, text message, or notification from an app like Facebook or Mail also wake your iPhone and present an action to take on the Lock screen.

      The Home button is the round, central button on the front of iPhone, below the screen. You can do the following:

      ✔ When iPhone is awake: Press this button once to return to the Home screen at any time from any app.

      Quickly press the Home button twice, also known as a double-click, to open the App Switcher and switch from one app to another. More about that in Book I, Chapter 3.

      ✔ When iPhone is asleep/locked: Press this button once to wake iPhone the same way as the Sleep/Wake button does.

      

If you have an iPhone with Touch ID, the Home button performs the above functions and houses the Touch ID sensor, which uses your finger to authorize iPhone access and purchases in place of a passcode or Apple ID.

       Turning Up the Volume

      When you’re in a noisy place and you don’t want to miss a call, you might want to have the ringer at full volume. On the other hand, if you’re in a meeting but waiting for an important call, you may want to keep your iPhone silent and choose to respond only to that one not-to-be-missed call. Likewise, you may want to increase the speaker volume to better hear the person you’re speaking with on a call in a noisy place. Here we explain how the three buttons on the left of your iPhone control volume:

      ✔ Volume buttons: You find the volume buttons – two round, slightly raised buttons – on the left side of iPhone. The button on top with the plus sign increases volume; the lower button with the minus sign lowers volume. When iPhone is awake, but not otherwise engaged in a noisy activity, these buttons control the volume of both the ringer and alerts, unless you’ve turned that feature off within the sound settings, as we explain in Book I, Chapter 4. When you’re engaged in a call or using an app that has volume – be it music, a video, or a game – these buttons control the volume of the thing you’re listening to, watching, or playing.

      Both volume buttons double as shutter buttons for the Camera. (Refer to Book IV, Chapters 1 and 4 to learn about using your iPhone’s camera and video recorder.)

      ✔ Silent/Ring switch: The switch above the volume buttons is a mute button. Push it to the back and you see a red bar. This is the off or silent position. Pushed to the front is the on or ring position. When iPhone is in silent mode, it vibrates when calls or alerts come in. If your iPhone rings and you prefer not to answer, you can turn the Silent/Ring switch off. Your caller continues to hear the phone ring until he decides to hang up or leave a voicemail message, but your iPhone will be silent although it will continue to vibrate. See Book II, Chapter 1 for information about declining calls.

      

When iPhone is in silent mode, alarms you set are still audible, which means you can put your iPhone in silent mode when you go to sleep but you’ll hear the alarm you set to wake you in the morning. The audio for Music and some games will be heard through the speaker or earphones, if you happen to have those plugged into your iPhone (and into your ears, of course).

Charging Your iPhone Battery

      Like all battery-powered gadgets, your iPhone is useless with an uncharged battery. The good news is that iPhone recharges in less than an hour, and you can charge the battery in several ways, which we describe here. Even though it recharges quickly, sometimes you want to conserve that charge for as long as possible; check out the sidebar at the end of this section for tips on helping your iPhone hold the battery charge longer.

       Plugging into the USB charger

      Your iPhone comes with a USB connection cable and a USB power adapter. To charge the battery, plug the dock connector into the dock port at the base of your iPhone, plug the USB end into the USB power adapter and plug the power adapter into an electrical outlet. iPhone beeps, which lets you know it’s actively charging.

      

The power adapter automatically adjusts to 110 or 220 voltage, based on the voltage for the location you’re plugging into. If you’re using your iPhone outside the United States, you have to purchase an adapter that changes the plug conformation to meet the outlet style of the country you’re visiting. You can find a kit at the Apple Store (http://store.apple.com/us) or single adapters at TravelProducts.com (www.travelproducts.com). If you use a MacBook, PlugBug World from Twelve South (www.twelvesouth.com) connects to the Mac’s power block and houses a USB port so you can charge your Mac and iPhone on the same outlet. Or you can charge your iPhone with your computer’s USB port, as we explain next.

       Charging with your Mac or PC’s USB port

      When you connect your iPhone to a USB port on your computer to sync or transfer photos, the battery automatically begins taking a charge. Again, iPhone beeps, which lets you know this is going on.

      

If your computer is turned off or is sleeping, your iPhone battery may drain instead of charge, so make sure your computer is on whenever you connect your iPhone to it.

      Although plugging your iPhone into any recent or new Mac can charge your iPhone, the same isn’t necessarily true for recent or new Windows desktop and laptop computers or older Macs. Apple explains that’s because the USB ports on certain models don’t pass through enough wattage to charge your iPhone. If connecting your iPhone to your USB port doesn’t yield a charge – you know it’s charging because it beeps and there’s a lightning bolt next to the battery in the Status bar – try plugging into a port dock on a powered USB hub. If that doesn’t work, you’ll have to plug into a charger to charge your iPhone.

      

Don’t pull the cable to detach your iPhone from your computer. Always
