Part 1: Why is my iPhone hot after iOS update?
There can be several reason why is my iPhone hot and losing battery after the iOS 18 update. Here’s the list of the potential culprits that can cause the iOS 18 heating issue:
- After installing iOS 18, your iPhone continuously updates the list of apps running in the background. This may increase the device's CPU usage, leading to overheating and faster battery drain.
- Buggy or incompatible iOS apps can use more power, leading to an overheating issue. iOS app developers take time to make their apps compatible with the new iOS 18 update. Thus, deoptimisation might be the culprit for the device.
- The update process itself is quite heavy and consumes a lot of power. After installing the new update, the device reindexes the data and calibrates the settings and apps.

Step 3: Once the device is fully turned off, press and hold the Power/Side button to restart it.
Method 3: Clear iPhone Storage
Low storage space on the iPhone has been known to be the culprit for overheating issues. When an iphone is running on low space, it’s working hard to perform even the basic tasks. Consider checking your device storage space, and delete the unnecessary files if needed.
Here’s how to clean iPhone storage effectively:
Step 1: Go to the Settings app, and tap on General.
Step 2: Navigate to the iPhone Storage, and analyze the storage space being consumed.
Step 3: If the device runs on low storage space, consider deleting the unnecessary apps, photos, and videos.
Method 4: Restore Default Settings
Your device is overheating, perhaps you've mistakenly turned certain features or settings causing the device to keep working hard, leading to battery drain, and eventually overheating issues. An effective way to deal with such a situation is resetting the setting to its default value.
The iPhone allows you to restore default settings without losing any data from the device. Here’s how to restore default settings:
Step 1: Navigate to the Settings app, and tap on the General option.
Step 2: Tap on Reset iPhone option, and select Reset All Settings.
Step 3: Enter your device passcode, and follow the onscreen instructions to reset the settings.
Method 5: Close Unnecessary Apps
Running too many apps in the background can also increase the battery consumption on the device, and cause overheating problems. The apps running in the background are continuously using the device resource and causing the ios 18 heating issue. Consider closing the unnecessary apps from the recent apps to cut off their background activity.
Steps to close unnecessary apps on iPhone:
Step 1: Swipe up from the bottom of the screen to launch the recent apps screen.
Step 2: Go through the apps card, and close the unnecessary apps by swiping them upward.
Method 6: Reduce Screen Brightness
Using an iPhone at full-screen brightness can also significantly overheat the device. The increased screen brightness also adds to the device's battery consumption, leading to faster battery drainage. Consider reducing the screen brightness when using it indoors.
You can turn on the auto-adjust brightness on the device to let the screen automatically adapt the brightness level required to the surroundings. Here’s how to enable it:
Step 1: Go to Settings and tap on Accessibility.
Step 2: Tap on the Display & Text Size option, then turn on the toggle for Auto-Brightness.
Method 7: Await the next update
If none of the above fixes resolved the iOS 18 overheating issues, then some stubborn bugs in the device must be addressed via a new software update. Consider checking the software update section in the settings of your iPhone regularly, and update your device to fix the issue.
