My iPhone 7 Is Hot! What Should I Do? Here’s The Fix!

In iPhone 7 by David Lynch

Your iPhone 7 gets hot, but you're not quite sure why. This problem may just be the result of leaving your iPhone out in the sun, or it could be caused by a software or hardware issue. In this article, I'll explain why your iPhone 7 is hot and show you how to fix this problem for good.

iPhone Temperature Warning

If your iPhone 7 gets hot when left out in the sun or in your car during the summer, it's normal to receive a temperature warning stating that you need to cool it down before using it again. iPhone's are designed to function only at temperatures between 32 – 95 degrees Fahrenheit to help protect its internal components.

The fix for this issue is quite simple — move your iPhone to a less hot location. If your iPhone 7 is hot and stops functioning, taking your iPhone to a cooler place or even putting it in the shade can be enough to lower your iPhone's temperature.

Software Troubleshooting

If you find that your iPhone 7 is hot a lot of the time, even when you don't receive the temperature warning, your iPhone may have a software issue. A lot of the time, your iPhone's CPU will be working at 100% capacity, which can cause your device to overheat. The steps below will help lower the workload on your iPhone 7's CPU and cool it down in no time!

How To Fix An iPhone 7 That Gets Hot

1. Turn Your iPhone Off And Back On

  • Turn Your iPhone Off And Back On
Turning your iPhone off and back on again can fix simple problems with your iPhone's software.

Why Should I Turn My iPhone Off And Back On?

When you turn off your iPhone, the operating system shuts down all the little background programs that keep your iPhone running. When you turn your iPhone back on, all those little background programs start fresh, and sometimes that’s enough to fix a simple software glitch.

How Do I Turn My iPhone Off And Back On?

  1. Press and hold the power button until “slide to power off” appears on the screen.
  2. Use your finger to swipe the red power button across the screen from left to right.
  3. Wait for your iPhone to turn all the way off. This may take up to 30 seconds.
  4. To turn your iPhone back on, press and hold the power button until the Apple logo appears on the screen.
  5. Let go of the power button and wait for your iPhone to turn on.

Pro Tips

  • In Apple jargon, the power button is known as the Wake / Sleep button.

2. Close Out Of Apps You Aren't Using

  • 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 I'm Not 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.

Pro Tips

  • Have an iPhone X or newer? Closing apps is a little bit different. Check out our other step to learn how to close iPhone X apps.
  • Make sure you are double-pressing the Home button, not double-tapping it. When you double-tap the Home button, you may activate Reachability mode, depending on which model iPhone you have.
  • You can close two apps at the same time in the App Switcher by swiping up on two apps at a time.
  • You won't lose any data when you close out of your apps. There's no downside to closing out of your apps!

3. Update Your iPhone Software In The Settings App

  • Update Your iPhone Software In The Settings App
When you update your iPhone software, you are installing the most recent iOS update. iOS is an operating system used for mobile devices made by Apple.

Why Should I Update My iPhone Software In The Settings App?

Apple puts out new software updates to improve efficiency, fix bugs, and introduce new features. Updating iOS can fix problems with your iPhone's software.

How Do I Update My iPhone Software In The Settings App?

  1. Open the Settings app.
  2. Tap General.
  3. Tap Software Update.
  4. Tap Install Now.
  5. Enter your passcode.
  6. The update will begin once it is verified.
  7. The update is complete after your iPhone restarts.

Pro Tips

  • You'll know there's a new software update if you see a red circle with a white "1" update available icon in it next to Software Update in Settings -> General.
  • To install the latest software update, your iPhone will either need to be plugged in or have 50% battery.

4. Reset All Settings

  • Reset All Settings
Reset All Settings doesn't erase any of the personal information from your iPhone, but it does restore everything in the Settings app to factory defaults. You'll have to optimize your battery settings, choose your favorite background image, and enter your Wi-Fi password again, but all of your apps, photos, and contacts will still be on your iPhone.

Why Should I 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.

5. DFU Restore Your iPhone

  • DFU Restore Your iPhone
A DFU (Device Firmware Update) restore is most in-depth reset you can do to an iPhone. A DFU restore uses your computer to erase and reload all the code that controls both the software and hardware on your iPhone.

Why Should I DFU Restore My iPhone?

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if  your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

How Do I DFU Restore My iPhone?

Watch our DFU restore video walkthrough on YouTube, or follow the steps below:

  1. Using a Lightning cable, plug your iPhone into a USB port on your computer.
  2. Open iTunes. It doesn’t matter if your iPhone is on or off.
  3. On an iPhone 7 or newer, press and hold the power and volume down button.  
  4. After 8 seconds, release the Power Button, but continue to hold the volume down button
  5. Let go of the volume down button when iTunes says “iTunes has detected an iPhone in recovery mode.”
  6. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
  7. Restore your iPhone using iTunes.

Pro Tips

  • If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.
  • Learn more about DFU restores in our article: How To Put An iPhone Into DFU Mode, The Apple Way.
  • A damaged component can prevent your iPhone from fully completing the DFU restore. If your iPhone is damaged in any way, a DFU may break your iPhone.
  • In Apple jargon, the power button is also known as the Sleep / Wake Button.

6. Repair Your iPhone With Apple

  • 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.

Pro Tips

  • If you're not sure whether your iPhone is still under warranty, you can find out on Apple's website.
  • Apple repairs are covered by a 90-day AppleCare warranty.
  • If you've ever used a 3rd-party service to repair your iPhone, or if you've ever replaced a part of your iPhone with a non-Apple part, then the Apple Store may not repair your iPhone. (Shhhh!)
  • In some cases, Apple will not repair devices that are older than five years old. These devices are classified as vintage or legacy.
