So first of all, why does an iPhone get hot?

Well to understand why you have to understand which part of the iPhone gets the hottest and that is the CPU or the central processing unit.

The CPU on an iPhone is designed to go from 0 to 100. So think about this, if you’re driving a car and you can put the pedal to the metal.

That’s okay to do for short periods of time. But what if you put the pedal to the metal and just held it there for minutes, your car engine will overheat and you will probably have a problem.

Well, that’s what happens when iPhones get hot. Usually, the CPU of your iPhone gets revved up to 100 and gets stuck there.

The most common reason for your iPhone to get hot is that one app has hijacked the CPU and it’s just going in the background even if you’re not using it. This means there’s something wrong with that app and you’ll need to uninstall it. You can do this by detecting the app in the settings > holding the app till the ‘x’ comes up > tap delete to confirm.

Close Apps Running in the Background

The first step to solving this issue is to close all the apps in the background. So, how do you do that?

1. Double click the home button and the app switcher will be activated

2. Swipe upwards to close apps

When they’re no longer there, this means they are closed.

This doesn’t delete any of the data in the apps.

When you open them back up, you’ll still have your data there. It’s just kind of like closing them on your PC.

Look for the App Causing the Problem

The next step in the process is to try to figure out which app is causing the problem. There’s a couple of ways to do this.

The first one is the scarier way which is to dive into the iPhones analytics to look for some problem apps.

To find this:

1. Open the settings app

2. Go down to privacy

3. Scroll all the way to the bottom of this window

4. Tap on the analytics

5. Then, tap on analytics data

When you open analytics data, you’re going to see a series of letters and numbers which may look confusing.

What you want to do is to scroll through the list briefly and see if you see the name of one app is repeated over and over and over again.

In simple terms, you’ll see the same line of jumbled up letters and numbers again and again.

You might see something called Latest crash and if you see ‘latest crash’ and the name of an app anywhere in the analytics data, you know that that app has a problem.

Look for Apps that are Using up Battery Life

So you’ve checked the analytics data. What’s the next? The next thing you’re going to do is to check which apps are using the most battery life because imagine this, if your iPhones CPU is revved up to 100%, then that app is going to burn through your iPhones battery.

Here’s what to do:

1. Open the settings app

2. Go down to battery

Under battery usage, your iPhone will display a list of apps that have used battery within either the last 24 hours or the last 7 hours.

All you’re going to do here is look for apps that are using battery too much.

If there is some app that you hardly ever use and it’s draining a large of the battery away, this is probably the app that’s causing the issue and you should uninstall the app or check for updates.

Check for App Updates

So you’ve just checked your battery settings for battery sucking apps.

The next thing you’re going to do is to check for app updates.

This is one of the reasons why your iPhone might be too hot.

Here’s what to do:

1. Go to the App Store

2. Tap the updates tab at the bottom of the screen

When there’s an update available, there’s usually a number and it’ll say how many are available.

You can either tap update next to one of the apps, or you can tap update all at the top.

If you have multiple updates, this will save you quite some time.

Update your iPhone to the Latest Version

iPhone software updates update the main software which can solve problems with apps that cause the CPU to overload your iPhone to get hot.

So how do we check for software updates?

Here’s how:

1. Go to the settings app

2. Scroll down and tap General

3. Tap software update

It’s going to check for an update.

Now if an update is available, it’s going to say the name of the update and what features are being added and then it’ll say download and install.

If your iPhone is up-to-date, it’ll say the version number your update is on.

Turn your iPhone off then Back on

So let’s say you’ve done all these steps and your iPhone is still getting hot.

The next thing you can do is to turn your device of and on again.

1. Press and hold the power button until ‘Slide to power off’ appears on the screen

2. Slide right and wait for your iPhone to turn off.

A lot of people get confused because as soon as they turn off their device, they think they can turn it back on straight away.

The truth is that even though there’s nothing on the screen right, it takes roughly 10-15 seconds for your iPhone the turn all the way off.

Reset all settings

The next steps you can take is your iPhone is still reaching high temperatures is to reset all settings.

Here’s how to do it:

1. Go to the settings app

2. Go back to General

3. Scroll down to the bottom and tap reset and then you’ll get a whole bunch of resets here

4. The one you’re going to do is reset all settings

Reset all settings is kind of a magic bullet to fix a lot of problems.

After you tap this, you’re going to enter your passcode and you’ll be asked to confirm the reset.

Resetting all settings does solve a lot of problems that are hidden in the background.

Little software problems can accumulate with time and this usually fixes them.

Perform a DFU Restore

If your iPhone is still hot, and none of this stuff worked, you’re going to have to perform something a lot more drastic.

The last step is to perform a DFU Restore. This stands for device firmware update. Make sure you backup your device before you perform a DFU restore. Trying doing an iCloud backup because errors come up a lot more frequently when doing an iTunes backup. A DFU restore is going to wipe everything off your iPhone, this why you need to backup.

Replace your iPhone Battery

The last option is to get your iPhone battery replaced because it’s most likely worn down and old. This is another reason why your iPhone can get too hot.

Going to the Apple store is the best option for this but, you’ll need to go to the store and schedule an appointment. After you’ve scheduled it, they will give you a date to come in which could take a few weeks.
