The iOS 18 update brings many new features and performance improvements for users, but some have reported iOS 18 overheating issues after the update. This overheating can affect device performance and may negatively impact the battery life and other hardware components of the iPhone. If your iPhone frequently overheats after upgrading to iOS 18, don't worry; we will delve into the reasons behind this and provide a range of solutions to help you address the issue.

Part 1. Why iPhone Keep Overheating After iOS 18 Update?

Does iOS 18 have a heating issue? If yes, the reasons for iPhone overheating after the iOS 18 update may include the following:

• Excessive system resource usage: The new system may require more processing power to run new features, causing the CPU to overwork and generate heat.
• Too many background applications running: The updated iPhone may allow more applications to run in the background, increasing the device's load. In this case, excessive background processes can lead to continuous CPU and battery consumption, resulting in overheating.
• Incompatible software issues: Some applications may not yet be optimized for iOS 18, leading to excessive system resource consumption.
• Environmental factors: High temperatures can affect the device's cooling ability, and combined with the system's heavy workload, this can easily lead to overheating.

Part 2. How to Fix iPhone Overheating After iOS 18 Update

To address the iOS overheating issue on iPhone, here are some effective fixes. Let's see how to fix an iPhone that overheated after the iOS 18 update together.

Fix 1. Remove Your iPhone Case

The case may hinder the device's heat dissipation, especially during heavy usage. You can try removing the case to give your iPhone more space for heat dissipation, helping to lower the temperature.

Fix 2. Avoid Extreme Temperature Environments

Ensure your iPhone is used within an appropriate temperature range. Apple recommends using the iPhone in temperatures between 0°C and 35°C. Avoid exposing the device to direct sunlight or extremely high temperatures to effectively mitigate overheating issues.

Fix 3. Close Running Applications

When too many applications are running in the background simultaneously, the device's processor and battery experience increased strain, leading to overheating. By closing unnecessary applications, you can lighten the load on your iPhone and help it cool down.

Here is how to do it:

Step 1. Swipe up from the bottom of the screen or double-click the "Home" button to open the app switcher.

Step 2. Swipe up on each unwanted application to close them.

Fix 4. Lower the Brightness

High brightness increases screen power consumption, leading to device overheating. By lowering the screen brightness, you can not only save battery life but also help reduce heat generation.

Here is how it works:

Step 1. Open the "Settings" app.

Step 2. Select "Display & Brightness".

Step 3. Adjust the brightness slider to reduce the screen brightness to a comfortable level for your eyes.

Fix 5. Disable Location Services

Location services activate the device's GPS module and other sensors, continuously increasing the load on the device, which can lead to overheating. Disabling or limiting the use of location services can effectively reduce temperature rise.

Here are the steps:

Step 1. Open "Settings" on your iPhone.

Step 2. Select "Privacy & Security", then tap "Location Services".

Step 3. Turn off Location Services or enable it only for necessary applications.

Fix 6. Enable Low Power Mode

Low Power Mode can reduce the usage of battery-draining features like background app refresh and automatic downloads, thereby lowering the device's resource consumption and helping to control temperature. This is an effective temporary measure, especially when the battery is low.

To enable the Low Power Mode, follow the steps below:

Step 1. Go to "Settings"> Tap on "Battery".

Step 2. Turn on "Low Power Mode" to reduce the overall load on the device.

Fix 7. Clear iPhone Storage

Insufficient storage space can affect the device's performance and heat dissipation. Clearing your iPhone's storage can help improve performance and reduce the likelihood of overheating. You can check your storage status with the following steps:

Step 1. Go to "Settings" > Select "General".

Step 2. Choose "iPhone Storage" to clean up unnecessary files, apps, and photos.

Fix 8. Update Applications

Ensure all applications are updated to the latest versions, as some outdated apps may be incompatible with iOS 18, potentially causing performance issues that lead to overheating.

Fix 9. Restart the Device

When the iPhone runs for an extended period, the system may experience temporary glitches or excessive resource consumption, leading to overheating. Restarting the device can clear the temporary cache and restore normal operating conditions.

To restart the iPhone, follow the steps below:

Step 1. Press any of the "Volume" buttons, then press and hold the "Power" button.

Step 2. Drag the slider to power off the device, and wait a few seconds.

Step 3. After the device is completely off, press and hold the "Power" button to restart it.

Fix 10. Update iOS System Patches

After the release of iOS 18, Apple may release subsequent system patches to address overheating issues. Regularly checking for and updating the system can help resolve heating problems caused by the system itself.

Open "Settings" > tap "General" > "Software Update" to check for available patches. (iPhone stuck on a software update?)

Here is how to do it:

Step 1. Open "Settings" on your iPhone.

Step 2. Select "General", then tap "Transfer or Reset iPhone".

Step 3. Choose "Reset All Settings" and enter your password to confirm the action.
