Close Out Of Apps You Aren't Using

When you don't close out of your apps, they stay loaded in the background so they'll be ready to go as soon as you open them back up. Problems really begin when one of those apps you have open in the background crashes, which can make your iPhone battery drain fast and possibly cause other apps to malfunction as well.

Apps left on in the background of your iPhone can also still send and receive data, which may slowly drain the amount of data your iPhone can use.

How Can I Check If One Of My Apps Has Crashed?

If you're ever wondering if an app is crashing on your iPhone, you can look for confirmation in the Settings app. Tap Privacy -> Analytics -> Analytics Data and check to see if any apps underneath LatestCrash.  If there are any apps listed here, then there may be a problem with those apps which is making them crash.

How Do I Close Out Of Apps You Aren't Using?

  1. Double-press the Home button to activate the App Switcher on your iPhone, which will display all the apps you currently have open.
  2. Using your finger, swipe up on the apps you want to close out of.
  3. You'll know the app has been closed when it's no longer displayed in the App Switcher.

Free Up Storage Space On Your iPhone

When your iPhone is low on available storage, it may operate slowly. You also may not be able to download more apps, music, pictures, or software updates. Freeing up storage space on your iPhone can be a fix for both of these problems!

How Do I Free Up Storage Space On My iPhone?

  1. Open the Settings app on your iPhone.
  2. Tap General.
  3. Tap iPhone Storage.
  4. At the top of this menu, you'll see how much storage space is available. If you have less than 1 GB of space available, it may be making your iPhone slow.
  5. To quickly free up some storage space, tap Enable next next to some of the features under the Recommendations submenu (see image 2).

Turn Off Background App Refresh

Leaving Background App Refresh on for many apps can significantly drain your iPhone's battery life because the apps will use your connection to Wi-Fi or data network to constantly download new data or information.

I recommend going through your apps one-by-one and determining which ones you want to allow to download new content even when you're not currently using it.

How Do I Turn Off Background App Refresh?

  1. Open the Settings app.
  2. Tap General.
  3. Tap Background App Refresh.
  4. Tap the switch next to the apps that you want to turn off Background App Refresh on. You'll know Background App Refresh is off on a particular app when its switch is gray and positioned to the left.

  1. Open the Settings app.
  2. Scroll down and tap Safari.
  3. Scroll down and tap Clear History and Website Data.

Reset All Settings

Many iPhone problems are caused when Settings isn't set up correctly or by corruption within individual Settings app files. Restoring the Settings app back to factory defaults doesn't fix every iPhone software problem, but it is a go-to fix for Apple technicians because it does solve a lot of problems that would be very difficult to to track down by hand.

How Do I Reset All Settings?

  1. Go to the Home screen.
  2. Open the Settings app.
  3. Tap General.
  4. Use your finger to scroll down to Reset. It will be the last option in Settings -> General.
  5. Tap Reset All Settings.
  6. Enter your passcode.
  7. Tap Reset All Settings. You'll be prompted twice.
  8. A progress bar will appear on the screen.
  9. Your iPhone will automatically turn back on when the reset finishes.

Repair Your iPhone With Apple

Apple repairs iPhones at the Genius Bar in Apple Stores and through their online mail-in repair service. Apple repairs are high-quality, but out-of-warranty repairs can be much more expensive than third-party solutions. If you're looking to save some money you're not covered by Apple's warranty, you may want to check out our other recommendations.

How Do I Repair My iPhone With Apple?

How To Repair Your iPhone With Apple's Mail-In Service

  1. Visit Apple's support website to begin the online mail-in repair process.
  2. Alternatively, call 1-800-MY-APPLE (1-800-692-7753) to set up a repair.

How To Repair Your iPhone At The Genius Bar Inside Your Local Apple Store

  1. Visit Apple's website to make a Genius Bar appointment before you go into the store. Apple Stores are extremely busy, and if you don't have an appointment, you may have to wait for hours or end up being turned away. (Editor's note: I'm a former Apple tech and we're not exaggerating — please, do yourself a favor and make an appointment first!)
  2. When you arrive, go to the Genius Bar to check in for your appointment.
  3. Genius Bar appointments always include free diagnosis. If you're under warranty, many repairs can be done on the spot, but it all depends upon which parts are in stock. If you're not under warranty, the Genius will give you a quote for the cost of a repair.
