Understanding the iPhone 15 Pro NFC and BMW Issue
One of the most concerning hardware issues to affect iPhone users involves the iPhone 15 Pro and certain BMW wireless charging pads. Reports emerged that using the in-car wireless charger in select BMW and Toyota Supra models could temporarily — or permanently — disable the iPhone's NFC chip. This affects critical features like Apple Pay, digital car keys, and contactless interactions.
Apple officially acknowledged the problem, noting that a "small number" of wireless chargers in recent BMW models could cause NFC failures in iPhone 15 series devices. The issue has been partially addressed through iOS software updates, but some users continue to experience complications, especially with BMW Digital Key Plus functionality after iOS 18 and later updates.
What Causes the NFC Failure?
Overheating from Wireless Charging
The primary suspected cause is overheating. BMW's wireless charging pads use the Qi standard to charge compatible devices. In some models, the charger can generate excessive heat that damages the iPhone's NFC controller chip. This is particularly problematic in enclosed charging compartments with limited ventilation.
Electromagnetic Interference
Some experts suggest that electromagnetic interference (EMI) from the car's electronic systems may contribute to the NFC malfunction. The close proximity of the NFC antenna to the wireless charging coil makes it vulnerable to interference from high-power charging signals.
Hardware Vulnerability
The iPhone 15 Pro uses a redesigned internal layout with titanium construction, which may affect heat dissipation differently than previous aluminum-bodied iPhones. This design change could make the NFC chip more susceptible to thermal damage during wireless charging.
Symptoms of NFC Damage
If your iPhone 15 Pro has been affected by the BMW charging issue, you may notice one or more of the following symptoms:
- "Could Not Set Up Apple Pay" error message
- Apple Pay becoming unavailable — cards disappear from the Wallet app
- NFC tags and readers not responding to your phone
- Digital car key failures — unable to unlock or start your BMW
- iPhone entering data recovery mode with a white screen after charging
- Express Transit cards not working in public transportation
BMW Digital Key Plus Problems After iOS Updates
iOS 18 Compatibility Issues
After updating to iOS 18 and later, some BMW owners reported their Digital Key Plus stopped working correctly. Specific issues include:
- Passive entry failure — the car no longer unlocks automatically when approaching with the iPhone
- Tap-to-unlock required — users must physically tap their phone to the door handle
- Start button issues — placing the phone on the charging pad doesn't always start the engine
- Key deactivation — BMW's servers deactivate the digital key after iOS updates

How to Fix iPhone 15 Pro NFC Issues
Immediate Steps
- Stop using the BMW wireless charger – This is the most important step. Avoid placing your iPhone on the in-car charging pad until the issue is resolved.
- Force restart your iPhone – Press and quickly release the Volume Up button, then Volume Down, then press and hold the Side button until the Apple logo appears.
- Update to the latest iOS – Apple released fixes in iOS 17.1.1 and later. Go to Settings → General → Software Update.
- Reset Network Settings – Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
Fix BMW Digital Key Issues
- Delete and re-add the Digital Key – In the My BMW app, remove the existing digital key and set it up again.
- Reinstall the My BMW app – Delete the app, restart your phone, and reinstall it from the App Store.
- Contact BMW dealer – Some digital key issues require a dealer to update the car's firmware.
- Reset Wallet – Remove all cards from the Wallet app, restart, then re-add them.
Hardware Repair
If the NFC chip is physically damaged, no software fix will restore it. In this case:
- Contact Apple Support – Schedule a Genius Bar appointment or chat with Apple Support.
- Apple may repair or replace your device, especially if it's under warranty or AppleCare+.
- Document the issue – Take screenshots of error messages and note when the problem started (after BMW charging).
How to Prevent NFC Damage
Use a Cable Charger Instead
The safest approach is to charge your iPhone using a Lightning or USB-C cable in your car. This avoids the wireless charging pad entirely and eliminates the risk of NFC damage.
Use a MagSafe Car Mount
A MagSafe-compatible car mount with regulated wireless charging can safely charge your iPhone without the overheating risks of built-in car chargers.
Monitor Temperature
If you must use wireless charging, monitor your phone's temperature. If it feels unusually hot, remove it immediately. iPhones display a temperature warning when they overheat. To preserve your battery health, read our guide on adjusting screen settings to extend battery life.
Alternative Digital Key Solutions
Physical BMW Key Fob
Always keep your physical BMW key fob as a backup. Digital keys are convenient, but they depend on phone hardware that can fail.
Apple Watch as Digital Key
If your iPhone's NFC is damaged, you may still be able to use your Apple Watch as a digital car key. The Watch has its own independent NFC chip and can operate the BMW Digital Key.
Samsung SmartThings Integration
BMW also supports digital keys for select Samsung Galaxy phones via UWB (Ultra-Wideband) technology. This could be an alternative if you switch devices. For more on Samsung technology, check our guide on Samsung Exynos processors.
Apple and BMW's Response
Apple's Position
Apple acknowledged the issue and recommended that affected users stop using the in-car wireless charger. Software fixes were included in iOS 17.1.1 and subsequent updates. For hardware-level NFC damage, Apple offers repair or replacement under warranty. Learn how to stay connected without NFC by reading about Wi-Fi calling.
BMW's Position
BMW stated that their wireless chargers are Qi-certified and comply with industry standards. The company has worked with Apple to investigate and resolve the compatibility issues, including firmware updates for the in-car charging system.
Frequently Asked Questions (FAQ)
Does this issue affect all iPhone 15 models?
The NFC damage has primarily been reported with the iPhone 15 Pro and iPhone 15 Pro Max, but some standard iPhone 15 users have also experienced issues. Earlier iPhone models seem less affected due to different internal designs.
Will Apple fix my iPhone for free?
If your iPhone is under warranty or covered by AppleCare+, Apple typically covers NFC-related repairs caused by this known issue. Out-of-warranty repairs may involve a fee. Contact Apple Support for specific pricing.
Is it safe to use other wireless chargers with iPhone 15 Pro?
Yes, standard Qi-certified wireless chargers and Apple's MagSafe charger are considered safe. The issue is specifically linked to certain in-car wireless charging pads in BMW and Toyota Supra vehicles. For help connecting your iPhone to Wi-Fi, see our guide on how to check Wi-Fi password.
Can I still use BMW Digital Key with an affected iPhone?
If the NFC chip is only partially affected, some digital key functions may still work (like tap-to-unlock). If the NFC chip is completely disabled, you'll need a hardware repair or must use an alternative (Apple Watch, physical key fob).
Has this issue been fully resolved in 2026?
Apple's software updates have mitigated the issue for most users, but some BMW models may still cause problems. The safest approach remains avoiding the in-car wireless charger and using a cable or MagSafe mount instead. Browse our collection of affordable smartphones if you need a backup device.
