• Prolonged exposure to direct sunlight, especially in a car or near a window on a hot sunny day 
• Using poorly designed iPhone 11 cases and covers

1. Reboot your iPhone

This method sounds so obvious, but trust me, rebooting can fix almost every minor issue that you face on your iPhone. So, if your iPhone 11 Pro is overheating often or you come across battery drain issues on the same device, we urge you to reboot it once. This way, you can get rid of different software issues that are causing your iPhone to overheat. Furthermore, rebooting can also fix iPhone not charging or slow wireless charging issues. Therefore, it is a must-try step and shouldn’t be skipped by any chance. 

Here’s how to reboot the iPhone 11 models:

1. Press and hold the Volume Up/Volume Down button and the Side button at the same time.
2. Next, swipe the slider left to right to turn OFF your iPhone.
3. Then, wait for a minute or so and hold the Side button until you see the Apple logo, and your iPhone is rebooted. 

Also, we recommend rebooting your device once in a while as it can vastly improve the performance as well as the battery health of your iPhone. 

2. Make sure you’re using the right case

As you all know, the market is full of iPhone 11 cases and covers. However, using the right one makes a difference, be it protection or heat dissipation. However, there are some cases that are not good at heat dissipation especially during charging as a result this causes overheating problems on iPhone 11 Pro Max. This happens mostly when you’re dodging bullets from your enemies in PUBG or playing resource consuming  games. So, you should be very conscious while choosing cases for your iPhone. That’s the reason why we always recommend getting cases and covers with an efficient heat dissipation design. 

To ease your case hunt, we have curated an extended list of best cases for iPhone 11 and iPhone 11 Pro. Please make sure to check it out.

3. Update iOS

Software updates are vital as they bring in loads of features and fixes for different problems that users are facing. So, if your iPhone 11 and iPhone 11 Pro get too hot without any reason, it is important to check if your device is running on the latest iOS version, iOS 15. It should be noted that the initial iOS update brings along some bugs and glitches which might be causing overheating issues on the iPhone 11. Fortunately, Apple releases updates over time for bug fixes, security patches, and performance enhancements. Therefore, if your iPhone 11 overheats without running any app, you should update your iPhone to the latest iOS version. In addition to that, if your iPhone 11 Pro Max battery drains overnight, you should also pay attention to the current iOS version your device is running in and for battery draining apps. We have talked about them later in this guide.

Are you not aware of how to check for software updates on iPhone 11? Here’s how to do it:

1. Open Settings > General
2. Now, tap on the Software Update
3. If there’s any update available, download and install it.  

If you’re still facing the overheating problems on iPhone 11 Pro after the iOS 15 update, please continue trying the troubleshooting methods we have mentioned below.

4. Use Low Power Mode

If you’re on the go and are looking for a quick method to prevent your iPhone 11 overheating and battery drain problems, we recommend using your device in the low power mode. This mode cuts down battery usage and restricts various features that are not necessary for the time being. You should be glad to know that Low Power Mode on iPhone adds about 2 to 3 hours of extra battery life and prevents various iOS 15 problems that users are facing. As it saves the battery very efficiently and prevents overheating problems on iPhone 11 Pro, it’s worth trying. 

Here’s how to put your iPhone in Low Power Mode:

1. Firstly, open the Control Center and tap on the Battery icon. Next, the battery icon will turn Yellow. 
2. Alternatively, you can go to Settings > Battery and turn ON the slider to enable Low Power Mode. 

Note: When your iPhone hits 20%, you are asked to enable the Low Power Mode. This mode is automatically disabled once the battery reaches 80%.

5. Disable Location Services (when you don’t need them)

Location services use GPS & mobile data (internet) to fetch results. If you keep it on every time, it runs in the background actively and eventually causes your iPhone 11 to overheat. Not only does this cause overheating problems but also leads to battery drain problems on iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. To prevent these issues from happening,

you can either turn OFF the location services altogether (useful for users working from home) or allow specific apps to access your location (for those who travel on a daily basis). 

Here’s how to disable location services on an iPhone:

1. Head to the Settings option
2. Tap on the Privacy 
3. Then, head to the Location Services
4. Now, turn OFF the Location Services entirely.

Just in case you’re looking to choose the latter option, tap on the apps and select from the following options mentioned below: 

Never: This will prevent the app from accessing your location.

Ask Next Time: The app will ask you every time it wants to track your location.

While using the App: The app can only track your location only when you’re using it.

Always: This allows the app to track your location even if the app is running in the background. 

As this method ensures optimum battery utilization, it may possibly prevent overheating problems on iPhone 11 Pro Max .

6. Turn OFF Background App Refresh

Still, annoyed by the overheated iPhone 11? You should try disabling the Background App Refresh option on your iPhone. No doubt, it’s a great feature that lets you stay updated with all the apps and services when you’re online. Unfortunately, this feature is a battery killer. Since the apps stay open in the background and deliver push notifications this tends to consume excessive power, resulting in overheating problems on your iPhone 11. So, you should check if the problems get resolved by disabling this feature.

Here’s how to disable the Background App Refresh feature:

1. Head to Settings 
2. Now, tap on the General option
3. Lastly, turn off the Background App Refresh option completely or do it for certain apps. 

Pro tip: If your iPhone 11 heats up quickly you should try disabling the Background App Refresh for all the social media (Instagram, Twitter, Facebook, etc.) as well as eCommerce apps such as Amazon, Walmart, etc. These apps run all the time in the background and send unnecessary push notifications.

7. Turn OFF features that you don’t need

iPhone 11 comes with a plethora of features, some are extremely useful whereas some are not that important in day-to-day life. Features such as Wi-Fi, Bluetooth, Mobile Data, Hotspot, and GPS are the ones we use almost every day, but forget to turn them OFF when they are not in use. That’s where the problem starts brewing. 

Since we keep these features ON, even if we don’t need them, they tend to run in the background searching for available signals, this especially happens in the basement areas where signals are quite poor. As a result, there’s a lot of load on the CPU as well as the battery which ultimately causes battery drain and overheating problems on iPhone 11. To prevent this, you can simply  turn off background usage of such services for apps that you don’t use.

Alternatively, you can configure Shortcut Automation to turn OFF the Wi-Fi automatically when you’re out of your house.

Here’s how to do it:

1. Open Shortcuts app > Automation 
2. Now, tap the “+” button on the top-right corner.
3. Next, tap on the “Create Personal Automation.”
4. Create an Action in new Shortcut Automation
5. From the next window, choose “Leave” under the “Travel” section.
6. Tap “Choose” from the next page, then select “Any” to run this automation anytime.
7. Then, select your location and set the radius within which the shortcut should run.
8. Now, tap Done.
9. Again, tap Next and go to the Actions page.
10. There, search for “Wi-Fi” and tap the “Set Wi-Fi” action.
11. Tap the “Add to this Shortcut” button.
12. Toggle the action into “Turn Wi-Fi Off.”
13. Tap “Next.”
14. Finally, overview your automation and then tap “Done.”

After you’ve created this shortcut, the automation will run and turn off the Wi-Fi on your iPhone automatically whenever you leave the specified area as mentioned in the map.

Outdated apps are another prominent reason why your iPhone 11 is overheating on iOS 15. Sometimes outdated apps act weirdly. On a daily basis, we might see some apps on our phones either crashing or loading very slowly or going blank when opened. This unusual app behavior can sometimes lead to overheating problems on iPhone 11 Pro as well. So, it is a wise move to keep your apps updated and make sure to read the reviews about the update from users. In case you come across plenty of negative recent reviews, it’s best that you don’t upgrade it as well.

1. Go to the App Store.
2. Now, tap on the Today tab at the bottom of your screen.  
3. Next, tap on the User Profile from the top-right corner.
4. Then, you’ll see your account details.
5. Now, scroll down the Available updates section.
