There are several possible reasons for this:
1. The distance between the wireless charger and iPhone 14 is too far or the Angle is incorrect. Wireless charging requires the iPhone 14 to be close to the surface of the charger, and the charging coils on the back of both are aligned. If the distance is too far or the Angle is not right, it may lead to ineffective charging.
2. The charging coil of the wireless charger is damaged. After prolonged use, the charging coil may be damaged, resulting in the failure of the wireless charging function. A new wireless charger may be needed.
3. The wireless charging coil module of the iPhone 14 is damaged. The iPhone 14's own wireless charging hardware can also be problematic, and may need to be repaired or replaced if the charger is detected but is unable to perform normal wireless charging.
4. The charging environment is subject to external interference. Sometimes the magnetic field or radiation generated by other electronic devices in the wireless charging environment will interfere with wireless charging, leading to charging failure or poor effect. This requires adjusting the charging environment away from other electronic devices.
5. The software is abnormal. Sometimes after the iPhone system software is upgraded, there will be some bugs that cause the wireless charging function to be abnormal. This is usually fixed some time after the release of a new updated version of iOS, which can be restored after the upgrade. If the wireless charging function still does not respond after taking the above measures, it may be a hardware fault of the iPhone 14 or the charger itself.
Apple's iPhone 14 doesn't support wireless charging. Please note that this answer is based on current information and the feature is subject to change due to Apple's future product plans. You are advised to determine whether the wireless charging function is supported according to the specific product specifications or official information.
