My iPhone 7 Plus Gets Hot! Here's The Real Solution.

JULY 12, 2017

It's summertime and you're trying to enjoy yourself, but your iPhone 7 Plus is getting hot. Once it gets hot, it stops working so you can text your friends to tell them to meet you by the pool. In this article, I'll explain why your iPhone 7 Plus is hot and recommend some fixes that will help cool it off.

"iPhone Needs To Cool Down Before You Can Use It"

If you've seen this message, it means that your iPhone 7 Plus is hot — too hot to function properly. Apple designed the iPhone to function from 32 to 95 degrees Fahrenheit, so anytime your iPhone is too warm or too cold, it may stop working unexpectedly.

When you see this message on your iPhone 7 Plus, the best thing to do is move it to a cooler area. Putting your iPhone in the shade or leaving it in an air conditioned room for awhile will cool it off in no time.

Troubleshooting For Software Issues

When your iPhone 7 Plus is hot, the problem may be the result of a software or hardware issue. A lot of the time, an iPhone will get hot when the CPU is working at 100% capacity.

The steps below will help you fix any potential software issues with your iPhone 7 Plus that keeps getting hot. I'll also wrap up this article with a couple of repair options if you're dealing with a hardware issue such as a faulty battery.

How To Fix An iPhone 7 Plus That Keeps Getting Hot

6 Steps Total
1.

Close Out Of All Of Your Apps

Closing out of your apps is like turning your iPhone off and back on — it gives your apps a fresh start. If one of the apps that you have open crashes in the background, it may prevent other apps you have open from functioning properly. It can be difficult to identify which specific app or apps are malfunctioning, so we'll close them all to save time.

How Do I Close Out Of All Of My Apps?

  1. Double-press the Home button to view the apps your currently have open.
  2. Use your finger to swipe up on the apps to close them.
  3. You'll know all your apps are closed when you only see a preview of your lock screen.

Turn Your 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 (iPhones without Face ID) or the side button and either volume button (iPhones with Face ID) until "slide to power off" appears on the screen.
  2. Use your finger to swipe the red power icon 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 on again, press and hold the power button (iPhones without Face ID) or side button (iPhones with Face ID) again until the Apple logo appears on the screen.
  5. Let go of the power button or side button and wait for your iPhone to turn on.

4.

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. Open the Settings app.
  2. Tap General.
  3. Scroll down and tap Transfer Or Reset iPhone.
  4. Tap Reset.
  5. Tap Reset All Settings.
  6. Enter your passcode, if prompted.
  7. Tap Reset All Settings again to confirm your decision.
  8. Your iPhone will shut down, complete the reset, and turn itself on again will automatically turn back on when the reset finishes.

DFU Restore Your 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.

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.

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.
