10 Effective Solutions to Fix iOS 26 Beta Overheating

Hello, I've installed iOS 26 Public Beta 1 on my iPhone 14 Pro max and it is getting heated up and battery is draining fast. Is this happening to anyone else? -- From Facebook

With the release of iOS 26 Public Beta, many iPhone users were excited to test out the new features and improvements. However, a growing number of users have reported a common issue: iOS 26 Beta overheating. From social media posts to tech forums, iPhone owners—especially those using new models—are noticing their devices getting unusually warm and experiencing rapid battery drain.

If your iPhone is hot to the touch or is draining power faster than normal after iOS 26 Beta update, you're not alone. In this article, we'll explore the possible causes behind the iOS 26 Beta overheating issue and share effective tips to cool down your device and protect its long-term health.

Part 1: Why Is My iPhone Overheating and Battery Drain After iOS 26 Beta Update?

If your iPhone is overheating and losing battery quickly after installing iOS 26 Beta, there are several potential reasons behind this behavior:

1. Background Indexing

After a major update like iOS 26, your iPhone begins re-indexing files, photos, and app data in the background. This process can take hours—or even a day—depending on your storage and usage, causing your device to heat up and consume more battery.

2. Beta Software Bugs

Since iOS 26 is still in beta, it's not fully optimized. Bugs or unoptimized code can lead to system processes overworking the CPU or GPU, generating heat and draining the battery.

3. App Incompatibility

Some third-party apps haven't yet been updated for iOS 26 compatibility. These apps might crash, lag, or constantly run in the background, leading to overheating and excessive power consumption.

4. Location and System Services

After an update, features like location tracking, Bluetooth, and system diagnostics may be more active than usual. These can stress your hardware temporarily, especially if left running without user awareness.

5. System Overload During Setup

Right after updating, your phone may be syncing iCloud data, refreshing app content, or reinstalling system files. All of this can spike CPU usage, resulting in a warm device and fast battery drain.

Part 2: Top 9 Solutions to Fix iOS 26 Beta Overheating

Fix 1. Restart Your iPhone

If you have encountered problems with your washing machine, TV, computer, or other electrical appliance before, you may had the experience that a technical maintenance staff will often ask firstly, "Have you turned it off and re-opened it?" Similarly, your iPhone needs to be reset as well. The easiest handling method for the overheating problem is to restart your iPhone. Here's how to do it:

Step 1: Press and hold the Side button and one of the Volume button.

Step 2: Slide to power off, wait 30 seconds, then press the Side button to turn it back on.

Fix 2. Force Restart Your iPhone

During beta testing, unstable code or unfinished system tasks can cause your phone's CPU to work harder than necessary, leading to excess heat. A regular restart might not be enough—but a force restart completely refreshes the system without affecting your personal data.

iPhone 8 and later: Press and release Volume Up, then Volume Down, then hold the Side button until the Apple logo appears.

iPhone 7/7 Plus: Hold Volume Down + Power button until you see the Apple logo.

iPhone 6s or earlier: Hold Home + Power button until the Apple logo appears.

This quick refresh can help cool things down fast.

Fix 3. Check Battery Usage in Settings

If the CPU of your iPhone is the engine, the battery will be the gasoline. If an app loaded on your device uses too much battery life, it will put a burden on your iPhone's CPU. If the application you are not using often occupies a disproportionate number of batteries, it may crash in the iPhone background. To avoid this situation, you can check battery usage by taking the following steps.

Step 1: Go to Settings > Battery.

Step 2: Scroll down to see which apps are using the most battery.

Step 3: If an app is using too much power, try force-quitting it or deleting and reinstalling it.

Fix 4. Disable Background App Refresh

In iOS 26 Beta, some apps may not yet be fully optimized and can continue running background tasks—like fetching updates, refreshing content, or syncing data—even when you're not using them. This constant activity can overwork your device, causing it to heat up and drain the battery faster. By turning off Background App Refresh, you give your phone a break from these hidden processes, allowing it to run cooler and more efficiently.

Step 1: Go to Settings > General > Background App Refresh.

Step 2: Set it to Off or Wi-Fi only.

Step 3: Or turn it off for specific apps.

Fix 5. Lower Screen Brightness and Disable Always-On Display

Lowering screen brightness and disabling Always-On Display can help fix iOS 26 Beta overheating by reducing the power demand on your iPhone's display—one of the main sources of heat. During beta testing, when the system may already be under stress, cutting back on screen activity helps the device stay cooler and run more efficiently.

Step 1: Swipe down to open Control Center, lower brightness manually.

Step 2: Go to Settings > Display & Brightness > Always On Display and turn it off.

Fix 6. Turn Off Unused Features Temporarily

Turning off unused features like Bluetooth, Wi-Fi, Location Services, and AirDrop can help fix iOS 26 Beta overheating by reducing background processes that continuously run and drain system resources. These features often stay active even when not in use, putting extra load on your iPhone's CPU and battery.

Step 1: Turn off Bluetooth and Wi-Fi if you're not using them.

Step 2: Go to Settings > Privacy & Security > Location Services and turn off or limit for non-essential apps.

Fix 7. Install the Latest iOS 26 Beta Version

Every time Apple releases the most recent versions, it will fix some corresponding errors. In case your iOS 26 Beta is overheating, you may check whether the iOS system on your iPhone is the latest one.

Step 1: Go to Settings > General > Software Update.

Step 2: Make sure you're on the latest beta version available.

Fix 8. Free Up iPhone Storage

When storage is tight, your iPhone has to work harder to perform basic tasks, which can lead to increased heat and lag—especially under the strain of a beta OS like iOS 26. By clearing out unused apps, large files, or offloading media to the cloud, you reduce the system load and give your device the breathing room it needs to run cooler and more efficiently.

Step 1: Go to Settings > General > iPhone Storage.

Step 2: Review what's using the most space.

Step 3: Delete unused apps or offload rarely used ones.

Step 4: Move photos and videos to iCloud, Google Drive, or an external drive.

A lighter system means less heat and better performance.

Fix 9. Reset All Settings

Sometimes, overheating after installing iOS 26 Beta can be caused by conflicting or corrupted custom settings. These hidden glitches might make your iPhone heat up even during light use. The good news? You can reset all settings without losing your photos, messages, or apps. This quick reset often resolves background issues that may be stressing your system.

Step 1: Open the Settings app. Scroll down and tap General. Swipe to the bottom and select Transfer or Reset iPhone. Tap Reset, then choose Reset All Settings.

Step 2: Enter your device passcode when prompted. Confirm your choice.

Your iPhone will restart, and all system settings—such as Wi-Fi networks, Bluetooth connections, display preferences, and more—will return to their factory defaults. This can help reduce overheating caused by software conflicts, without touching your personal data.
