After upgrading to iOS 26, some iPhone 15 users Series, particularly those with the iPhone 15 Pro models, have reported encountering significant issues such as black screens and charging failures. These problems have been especially prevalent among early adopters of the iOS 26 Beta version. Phonefix aims to provide practical solutions for users facing these issues and offer preventive measures to avoid further complications.
Understanding the Issue
Shortly after the rollout of iOS 26—particularly the Beta versions—multiple users reported that their iPhone 15 Pro or Pro Max devices became completely non-functional following the update. The most common symptoms include:
-
A completely black screen with no display output.
-
The device is unresponsive to button presses.
-
The phone refuses to charge via Lightning or MagSafe.
-
No haptic feedback or sounds — appearing "dead."
This issue appears to be more prevalent among users who installed iOS 26 Beta builds, indicating a potential software-level failure, possibly affecting bootloader or battery/power management systems.
If the device still has power: Try emergency recovery
If your iPhone still has some power left, you can try the following ways to fix it yourself:
1. Force restart
Quickly press and release Volume Up;
Quickly press and release Volume Down;
Press and hold the Power button (Side button) until you see the Apple logo.
This is the most basic but effective "soft reset" operation, suitable for situations where the system is stuck but still has power.
2. Restore using a computer (Finder/iTunes)
If the forced restart doesn’t work, you can try the following:
Connect your iPhone to a Mac or Windows computer using a USB-C data cable;
Open Finder (macOS Catalina and above) or iTunes (Windows/macOS Mojave and below);
Put the device into Recovery mode and select "Update" or "Restore" to restore to an earlier version.
⚠️ Note: The restore operation may cause data loss, so it is recommended to back up before upgrading.
What If the Battery Is Fully Drained?
If your iPhone is completely drained and refuses to charge, standard recovery methods won't work. Based on feedback from tech repair professionals, the only known solution is:
Disassemble the Device and Reconnect the Battery
-
Open the Device: Carefully use the Vacuum Suction Cup to lift the back cover. Once the cover is loosened, use a plastic pry to detach the cover without causing any damage.
-
Disconnect the Battery: Use the Spudger Opening Pry Tool to safely disconnect the battery from the logic board. Ensure that the device is powered off completely to avoid any electrical hazards.
-
Wait for 10-20 Seconds: Keep the battery disconnected for around 10-20 seconds to allow the internal system to reset.
-
Reconnect the Battery: After waiting, carefully reconnect the battery to the logic board using YCS Titanium Alloy Tweezer if necessary. Ensure the connection is secure.
-
Reassemble and Power On: Once the battery is reconnected, carefully reassemble the device and attempt to
-
Power it on: If successful, the phone should boot up and charging functionality should return.
⚠️ Important Note: This procedure should only be performed by professional technicians. Opening the device carries risks and can void your warranty. It's strongly recommended to have this done at an authorized Apple repair center.
The Risks of Installing Beta Software
Installing iOS Beta versions always carries risk, especially on your primary device. Beta builds are meant for testing and may contain critical bugs like the one described above.
It's important to note:
-
Apple support will typically require your device to be on the latest public (stable) release before offering official assistance.
-
Devices on Beta software may not be eligible for standard warranty repairs unless reverted to a public build.
How to Prevent This in the Future
To avoid similar issues, here are some best practices:
-
Never install Beta software on your primary phone unless you are a developer or tester.
-
Always back up your device (via iCloud or computer) before any major upgrade.
-
Wait for the stable public release, especially if you're not prepared for troubleshooting or data recovery.
-
Monitor tech forums, Apple developer notes, and official announcements for early feedback before upgrading.
To summarize, if you encounter a black screen or charging failure after upgrading to iOS 26, first check if the battery is completely drained. Then, attempt a force restart and clean the charging port. If the issue persists, try restoring the device using Recovery Mode. For hardware-related problems, such as a damaged charging port or screen, it's best to contact Apple Support or an authorized service provider. Alternatively, Phonefix offers high-quality and reliable phone repair tools to fix a wide range of iPhone issues.
