1. On the Home screen, tap Settings.

2. Tap General.

3. Tap Software Update. The app checks for an update. If one is available, you see information about it and should proceed to step 4. If no update is needed, you see a message saying so and you can skip the rest of these steps.

4. If automatic update downloads are enabled, tap Install Now; if not, tap Download and Install. The update is downloaded if it hasn’t been already and the installation process begins. You might see a brief prompt asking if the update should be installed; you can tap Install or just ignore it and the installation starts automatically. Depending on your iPhone’s status, you might see different warnings, such as if you aren’t connected to a power supply.

5. Enter your iPhone’s passcode.

6. Tap Agree.

7. Tap Agree at the prompt. The software update installs on your iPhone. As part of the update process, the iPhone restarts. When it does, the updated iOS software is ready for you to use.

1. Tap Settings.

2. Tap your Apple ID account.

3. Tap iCloud.

4. Swipe up the screen.

5. Tap iCloud Backup.

6. Tap Back Up Now. Your iPhone’s data is backed up to iCloud. You can see the progress on the screen; however, you can continue using your iPhone because the process works in the background. You just need to start the manual back-up process, and then do whatever you want while it completes.

1. Use a web browser to move to and log in to your iCloud website located at icloud.com.

2. Click Find iPhone. All the devices associated with your Apple ID and on which Find My iPhone is active are located.

3. Click the All Devices menu. All your devices are shown on the My Devices list.

4. Click the device you want to locate. If the device can be located, you see it on a map. You can use the map’s controls to zoom into the iPhone’s location so you get the best idea of where it currently is. You also see a dialog box that enables you to perform the three actions described earlier. The details for each are provided in the following tasks.

1. Locate your iPhone as described in the previous task.

2. Click Play Sound. The alert sound plays on the iPhone and the FIND MY IPHONE ALERT appears on the screen.

3. To stop the sound from playing on the iPhone when the phone is locked, press the alert if you are using a model with 3D Touch or swipe to the right on non-3D Touch models.

4. Tap X on models with 3D Touch or tap Clear on non-3D Touch models to stop the sound and delete the alert.

5. If the iPhone isn’t locked when the alert plays, tap OK to stop the sound and close the alert.

1. Locate the device using the steps in the previous task.

2. Click Lost Mode. (If you haven’t entered a passcode, you’re prompted to create one by entering and verifying it.)

3. Enter the phone number you want someone to call if your phone is found.

4. Click Next.

5. Enter the message you want to appear on the iPhone. This can be your request that whoever has the device call you, instructions for returning the device, and so on.

6. Tap Done. The iPhone is locked and the message you entered displays on the screen. While the iPhone is in Lost Mode, the Lost Mode icon on the Find My iPhone screen rotates and you see the Lost Mode indicator.

When the device enters Lost Mode, it is locked and protected with the existing passcode. The phone number and message you entered appear on the iPhone’s screen. The person finding your phone can tap Call to call the number you entered.

In addition to being locked, the phone is placed in Low Power Mode so the battery’s charge lasts as long as possible. Apple Pay is also disabled.

The iPhone remains in Lost Mode until it is unlocked. You see the current status in the iPhone’s window on the iCloud Find iPhone website. When you get your phone back, you can unlock it. You might need to re-enter your Apple ID password to restart iCloud services and re-enable Apple Pay.

1. Locate the device using the steps in the task “Using Find My iPhone to Locate Your iPhone.”

2. Click Erase iPhone.

3. Click Erase.

4. Enter your Apple ID password.

5. Click the right-facing arrow.

6. If you want to send a phone number to the device so that someone can call you about it, enter it at the prompt.

7. Click Next.

8. Enter the message you want to appear on the iPhone. This can be your request that whoever has the device call you, instructions for returning the device, and so on.

9. Tap Done. The iPhone is erased and the message you entered displays on the screen. The person who finds it can tap Call to call the number you entered in step 6, hopefully to return your iPhone. If it does get returned, you have to restore the iPhone using a backup from iCloud or iTunes on your computer (the steps to do this are later in this chapter).

1. Open the Settings app and tap Battery.

2. To manually activate Low Power Mode, set its switch to on (green); to leave it in automatic mode, skip to step 4.

3. To return your phone to normal operation, set the Low Power Mode switch to off (white).

4. To see the percentage of charge remaining along with the battery icon, slide the Battery Percentage switch to on (green). The percentage of charge remaining appears to the left of the battery status icon at the top of the screen. (This happens automatically when you put the iPhone into Low Power Mode.)

5. Swipe up the screen to see the BATTERY USAGE section. This provides information about the percentage of power that apps have used over the last 2 hours, which can come in handy when you want to make your battery last longer (see the next task for details).

6. Tap the Clock icon to see the amount of time the app has been running to use the percentage of power it has consumed. You see this both for on-screen or background activity.

7. Swipe all the way up the screen to see information about the time since the last full charge that your iPhone has been in use or has been in standby.

1. Use steps 5 through 7 in the previous task to identify apps using a large percentage of power.

2. If you identify a power-hungry app that you don’t want to use any more, press the Touch ID/Home button twice (all models except iPhone X) or swipe up from the bottom of the screen and pause toward the middle of the screen (iPhone X) to open the App Switcher.

3. Swipe to the left or right on the App Switcher until the power-hog’s screen is front and center.

4. Swipe up on the app’s screen to shut it down. You can use your iPhone to see if that was the cause of the rapid power drain. If so, you’re done. If not, you can continue with these steps to conserve power.

5. Open the Settings app and tap Accounts & Passwords.

6. Tap Fetch New Data (if you have a lot of accounts, you might need to swipe up the screen to see it).

7. Slide the status switch for Push to off (white). This disables Push functionality. To update your information, set a Fetch schedule using the controls on the bottom of the Fetch New Data screen or just open an app, such as Mail.

8. Turn off any transmitting and receiving functions that you aren’t using, such as Bluetooth. Using the Control Center is a handy way to do this quickly.

9. Use your iPhone to see if the battery lasts longer. If it does, you know one of the changes you made was the reason; you can either leave the offending source of power drain shut down or just be aware when you are using it. If the battery still doesn’t last very long, it might have a problem and you should contact Apple for assistance.

1. Press the Touch ID/Home button twice (all models except iPhone X) or swipe up from the bottom of the screen and pause toward the middle of the screen (iPhone X). The App switcher opens.

2. Swipe to the left or right until you see the app that has frozen.

3. Swipe up on the app to shut it down.

4. Press the Touch ID/Home button (all models except iPhone X) or tap outside the App Switcher (iPhone X) to move back to the Home screen.

5. Open the app again. If it works normally, you’re done. (It’s generally a good idea to restart your iPhone when you’ve had to force an app to quit.)

1. Press and hold the Side button (on 5s and SE models you use the Wake/Sleep button instead) until the slider appears on the screen.

2. Drag the slider to the right. The iPhone powers down and the screen goes completely dark.

3. Press and hold the Side button until you see the Apple logo on the screen. The iPhone restarts. When the Home screen appears, try using the iPhone again. If the problem is solved, you’re done.

1. On the Home screen, tap Settings.

2. Tap General.

3. Swipe up the screen until you see the Reset command.

4. Tap Reset.

5. Tap the Reset command for the area in which you are having problems. For example, if you are having trouble with Wi-Fi or other networking areas, tap Reset Network Settings, or if you decide your Home screens are a mess and you want to go back to the default layout, tap Reset Home Screen Layout. If you are having lots of issues in multiple areas, tap Reset All Settings or Erase All Content and Settings (be careful because this erases everything on your iPhone).

6. If prompted to do so, enter your passcode; if you don’t see a passcode prompt, skip to the next step.

7. Tap the confirmation of the reset you are doing. The reset is complete and that area of the iPhone is reset to factory conditions.

8. Reconfigure the area that you reset. For example, if you reset your network settings, you need to reconnect to the networks you want to use. If you did a Reset All Settings or Erase All Content and Settings, you basically start from the beginning as if your iPhone was just taken out of its box.

1. Move to a Home screen.

2. Swipe down from the center top area of the screen. The Search tool opens.

3. Tap in the Search bar and enter the name of the app that is missing. As you search, you see a list of items that match your search. If the app is found, you know it is still on the iPhone and its icon was just accidentally misplaced; you can continue with these steps to find it.

If the app you are looking for isn’t found, it has been deleted from the iPhone and you need to reinstall it. Download and install it again using the App Store app (don’t worry; if it has a license fee, you don’t need to pay for it again). (Installing apps is covered in Chapter 4.)

4. Tap Search.

5. Note the current location of the app, which is shown on the right side of the screen. If no location is shown, the app is on one of your Home screens, in which case you need to browse through the screens to find it, and you can skip the rest of these steps.

6. Tap Cancel. You move back to the Home screen.

7. Open the folder where the app is currently located.

8. Touch and hold on the app icon until the icons start jiggling.

9. Drag the app’s icon out of the folder and place the icon back where you want it to be (refer to “Customizing Your Home Screens” in Chapter 5, “Customizing How Your iPhone Looks and Sounds,” for details of moving apps on the Home screens).

10. Press the Touch ID/Home button to lock the icons in their current positions (all models except iPhone X).

1. Look at the top of the screen. If you see the Orientation Lock icon, the iPhone’s orientation is locked.

2. 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) to open the Control Center.

3. Tap the Orientation Lock button. Note that when Orientation Lock is on, the button’s graphic is red. When it is off, the button’s graphic is white.

4. Confirm that the Orientation Lock icon at the top of the screen has disappeared. The iPhone now changes orientation when you rotate it.

1. Open the app through which the person you want to block is trying to contact you; you can use Phone, Messages, or FaceTime. These steps show the Phone app, but blocking people with the others is similar.

2. Tap Recents.

3. Tap the Info (i) icon for the person you want to block.

4. Tap Block This Caller.

5. Tap Block Contact. The contact becomes blocked, and you no longer receive calls, messages, or FaceTime requests from them. When the person who is blocked tries to contact you, the attempt fails, but the person doesn’t know that the reason it failed is that you blocked him.

1. Make sure the iPhone isn’t muted. The Mute switch on the left side of the iPhone should be in the position toward the front of the phone. If you see color in the switch, the phone is currently muted. Slide the switch toward the front of the iPhone to unmute it. You should hear sounds again.

2. With the iPhone unlocked, press the upper volume switch on the left side of the iPhone to make sure that the volume isn’t set to the lowest level. As you press the button, a visual indicator of the current volume level appears on the screen. As long as you see a few “dots” on this indicator, you should be able to hear sounds the iPhone makes.

3. Make sure that the iPhone is not in Do Not Disturb mode by opening the Control Center and ensuring that the Do Not Disturb icon is off (the moon is white); if it is turned on (the moon is purple), tap it to turn it off. In Do Not Disturb mode, sounds are not made, such as a ring when you receive a phone call.

4. Try a different app or task. If you aren’t hearing sound from only one app and everything else sounds normal, you know there is a problem with that app. Try deleting and reinstalling it. If you still don’t hear sound from any app, you know the problem is more general.

5. Move to Sounds & Haptics in the Settings app.

6. Make sure the volume slider is set to at least the middle position.

7. Tap Ringtone.

8. Tap one of the default ringtones. You should hear it. If you do, you know the problem is solved. If not, continue.

9. If you aren’t hearing sounds when the EarPods aren’t plugged in, connect the EarPods and repeat the sound you should be hearing. If you hear the sound only when the EarPods are plugged in, try removing the EarPods and plugging them back in a few times to see if that solves the problem. If not, your iPhone needs to be serviced by an Apple authorized repair center, or you can take it to the Genius bar in an Apple Store.
