8 Ways to Fix iPhone 16/17 Overheating While Charging (iOS 26 & 27 Supported)

Hi, 

Lately, I discovered my iPhone 17 Pro is always overheating while charging it. This is alarming, as I don’t know why such is happening. Please, who knows how to fix iPhone overheating when charging issues? Kindly help with the solutions!

iPhone overheating when charging remains a persistent headache for Apple users. Whether you are rocking the older iPhone 15 or experiencing the notorious iPhone 16/17 Pro setup thermal throttling under fast charging, you are not alone. While Apple occasionally addresses these via updates (like the previous iOS 17.0.3 patches), heavy background indexing in iOS 18 and newer systems can still make your device feel like a hot brick. Here is how to cool it down instantly.

Why Is My Phone Overheating While Charging?

Before diving into the fixes, it is crucial to understand that not all heat is bad heat.

• PD Fast Charging Stages: When you plug your iPhone into a 20W or higher fast charger, it pumps massive energy from 0% to 50%. This high-voltage phase naturally generates physical heat.
• MagSafe & Wireless Charging: Wireless charging loses around 30-40% of its energy as ambient heat. If you use MagSafe with a thick case on, that heat gets trapped inside.
• The “Charging on Hold” Warning: If your iOS screen flashes a “Charging on Hold” notification, don’t panic. It is Apple’s built-in safety mechanism protecting your battery health until the temperature drops.
  Just before we go into the solutions to fix iPhone overheating while charging issues, let’s look at some of the reasons why you may experience such on your device. Find below why your iPhone is overheating while charging:
• Faulty or Bad iPhone Charging Equipment

Faulty or bad iPhone charging equipment is one of the chief reasons why your device is overheating while charging. This is because faulty charging equipment won’t regulate the amount of electric current disseminated into your phone battery, thereby causing overheating. In this case, you need to get the original charging equipment for your device. 

• Improper Operation

Are you running some operations on your iPhone while charging it? There’s a possibility the device will overheat when charging. Experts suggest that you stop all operations while charging your iPhone. This solution helps you fix the overheating issue. 

• Environmental Condition

The weather condition in your location also has a significant effect on how your iPhone will react while charging it. When you charge your device in very harsh weather conditions, the iPhone will surely overheat. Changing your location is the best thing to do in this scenario. 

• Software Issue

Another potential reason for iPhone overheating issues is software or iOS problems. Temporary errors and bug attacks often damage a device’s operating system (also known as software), causing it to malfunction. To fix this, you need to repair the software or update the iOS. 

Fix 1. Please Unplug Your iPhone Immediately

Is your new Apple iPhone 15/17 overheating when charging? The first thing to do when you notice your iPhone overheats when charging is to unplug or disconnect the device from power immediately. We suggest this solution because device overheating while charging indicates two things:

• Another practical way to cool down your overheating iPhone is to detach all accessories, especially pouches/cases, as they often trap heat.  
• Leave any location with harsh weather conditions.

Fix 4. Stop Crashing App and Remove It to Fix iPhone Overheating

Installed apps can also cause iPhone overheating when charging. If you notice your device is malfunctioning or radiating excessive heating while running an application, it’s high time you delete the app from your system. In a situation where you have numerous apps running on your iPhone and don’t know which one to delete, here’s a quick guide to spot it and get rid of it: 

• Navigate to the Settings app page on your iPhone by hitting the gear icon. 
• Choose Privacy on the next interface displayed. 
• Next, head down to where you have Analytics, click on it, and tap on Analytics Data to proceed. 
•  Another interface with the list of applications crashing or disrupting the operations of your iPhone will come. Note down the apps, and head to your home screen to delete each one of them. 

Fix 5. Turn Off the Background App Refresh

Apple smartphones are designed to update all operations of every app installed on them. It doesn’t matter whether you’ve opened the app or not. Although this is a great thing, as you are provided with all important data/info from each app in real-time, background app refresh often slows down the operations of a device in the long run. 

Background app refresh overworks your CPU and can cause the device to expel a great amount of heat while charging. To rectify or solve this issue, you have to deactivate the background app refresh from your iPhone. Here’s how it’s done: 

• Hit the gear icon displayed on your home screen and a panel labeled Settings will come up. 
• Choose General on the interface shown and select Background App Refresh. 
• Now, toggle the slider beside Background App Refresh from green to white to deactivate it. 

Fix 6. Use Airplane Mode to Fix iPhone Overheating

Sometimes iPhone overheating could be a result of your network server. When your device struggles to find service, it overworks the CPU, which can cause it to release an exceedingly high amount of heat while charging. All you need to fix this is to activate Airplane mode. 

Airplane mode regulates your iPhone temperature by deactivating all operations requiring network service. You can use the simple instructional guide here to enable Airplane mode on your iPhone: 

• Open the Settings menu on your device. To do that, hit the gear/cogwheel icon you have on your iPhone home screen.  
• Next, toggle the slider you have beside the Airplane tab to green. 
• Wait a while, then drag the slider left to deactivate it when your iPhone stops overheating. 

Alternatively, you can swipe down from the top right corner of your iPhone screen (strictly for iPhone X and later models), then tap on the Airplane icon to turn it off and on. For folks with iPhone 8 and older models, swipe up from the bottom of your screen to access the control center. Once done, click the appropriate icon to shuffle between Airplane activation and deactivation. 

Fix 7. Use Low Power Mode to Fix iPhone Overheating

Low power mode is a battery regulation feature tucked into all Apple smartphones to help end-users optimize battery power by reducing the operations of every app running on the device. This feature also plays a nice role in fixing iPhone overheating issues. 

With low power mode, you can easily manage the CPU activities on any iPhone to a great extent. Follow this simple guide to activate low power mode on your device: 

• Head to your iPhone Settings menu by hitting the gear icon displayed on your home screen. 
• Proceed to where you have Battery and click on it. 
• Next, slide the icon beside Low Power mode green to enable the feature. 

Quick Note: When you enable low power mode while charging, your device automatically deactivates the feature on getting to 80% battery life. So you have to recheck the device when using this feature to regulate the heat expelled.
