Resolving iOS 18/26 Beta Overheating After Update: A Comprehensive Guide [2025]

Part 1. Why is the iPhone Overheating after iOS 18/26 Beta Update?

There can be several reasons why your iPhone is hot and losing battery after the iOS 18/26 Beta update. Here's the list of the potential reasons that can cause the iOS 18/26 Beta heating issue:

• Buggy Apps

One of the most common reasons for iPhone overheating after updating to iOS 18/26 beta is the presence of apps that haven’t been fully optimized for the new system. Since beta versions are still under development, many third-party apps may not yet support the updated framework. As a result, these apps can consume excessive CPU power, drain the battery faster, and generate unnecessary heat.

• Background app Refresh

One likely cause is your iPhone performing intensive background tasks right after the upgrade. Once the new iOS beta is installed, your device automatically begins re-indexing system data, refreshing background apps, updating app libraries, and optimizing settings to align with the new firmware.

• Battery Drain

If you notice your iPhone’s battery depleting unusually fast after installing the iOS 18 or iOS 26 beta, it's often a sign that your device is overexerting itself. This excessive processing—whether from system updates, background syncs, or app reconfigurations—generates extra heat, leading to the common issue of iOS 18/26 Beta overheating after update. High CPU usage, combined with battery strain, not only shortens battery life but also raises internal temperatures, which can affect performance.

• Overworked Processor

This post-update strain can result in elevated CPU usage, causing your iPhone to heat up. This is a common cause of the iOS 18/26 Beta overheating after update issue reported by many users. While this behavior is often temporary, it’s important to monitor it closely. If overheating persists beyond a day or two, further troubleshooting steps may be needed to prevent long-term performance issues.

Now that you know why the iOS 18/26 beta overheating after update. Next, let’s explore how to fix the issue!

This puts extra strain on the processor, which leads to increased heat output and performance issues.

Here is how you can clean iPhone storage effectively.

Step 1. Go to the Settings application and tap on General.

Step 2. Go to iPhone Storage and check how much space is being used.

Step 3. If your device runs on low storage space, consider deleting the unnecessary apps, photos, and videos.

That's all about clearing your iPhone storage. It will resolve the iPhone overheating problem. However, if it doesn't, worry not! You can try the next method.

Fix 5. Restore Default Setting

If your iPhone is overheating after the iOS 18/26 beta update, certain features or customized settings might be pushing your device to work harder than usual. These settings can cause excessive battery drain and increase heat generation, worsening the overheating issue. Resetting your iPhone’s settings to default can often resolve this problem by eliminating conflicting or resource-heavy configurations.

The iPhone lets you restore default settings without losing data. Here’s how to do it:

Step 1. Go to Settings application and click on the General option.

Step 2. Click on the Reset iPhone option and choose Reset All Settings.

Step 3. Now, enter your iPhone’s passcode and follow the onscreen instructions to reset all the settings.

We have covered everything to restore the default setting. Now, let's jump to the next method to fix iOS 18 beta overheating after update.

Fix 6. Reduce Screen Brightness

Using an iPhone at full brightness can cause overheating. High brightness also drains the battery faster. Reduce screen brightness when indoors.

Enable auto-adjust brightness to let the screen adapt to the surroundings. Here’s how to enable it:

Step 1: Go to Settings application and click on Accessibility.
