iphone 15

Means individuals have been utilizing the technology for approximately 15 years, and it has proven to be quite reliable during that period. However, if you happen to be part of the group of individuals who currently own both a BMW and an iPhone 15, it might be advisable to charge your sleek smartphone using traditional methods.New iPhone users online have raised concerns about the charging pads in their BMW vehicles, which are causing damage to the NFC chips within their new phones. This results in the inability to use contactless payments, certain digital car keys, and other NFC-related features.As reported by MacRumors, individuals encountering the issue have expressed that during the charging process, their iPhones exhibit a white screen and enter recovery mode. After restarting, everything seems normal until the user attempts to utilize any NFC-dependent function.

Users possessing affected devices will then observe an error message within the Wallet application stating "Could Not Set Up Apple Pay." At present, no solution has been identified, although some customers have reported that Apple replaced their faulty devices subsequent to the occurrence of the error.

"[T]his has occurred with my friend's newly acquired iPhone 15 Pro Max from the local Apple Store last week," shared an individual on the /r/BMW subreddit. "Upon visiting the store, Apple employees confirmed that it cannot be rectified, thus resulting in a refund. The larger issue was the unavailability of another iPhone 15 Pro Max for purchase. Their only course of action was to place a new order with an estimated delivery date during the first week of November."The MagSafe charging array within an iPhone is a notable feature introduced by Apple. While Qi charging and NFC operate at different frequencies, they both utilize inductive coupling for data transmission at close range.

NFC operates at a power frequency of 13.56 MHz, which is relatively low. Although it technically supports charging, its capabilities are limited due to a maximum negotiated charging rate of only 1 watt. NFC is primarily used for data transmission, particularly in cases where proximity is essential. In the case of iPhones, NFC is employed for functionalities such as Apple CarKey and Apple Pay contactless payments.

On the other hand, Qi is a dedicated charging standard designed to facilitate wireless power transmission between a charger and a device, eliminating the need for cables. Previous Apple devices operated at around 127.7 kHz, while newer devices equipped with the Qi2 standard are capable of receiving 15 watts of charge at 360 KHz.

However, it remains unclear how or even if the NFC radio is being damaged. The Qi charging and NFC radios utilize separate antennas located in different parts of the phone. Presumably, the antenna locations remain unchanged in the iPhone 15.

As a proponent of Apple CarKey, BMW has been one of the earliest adopters of this feature in the United States. NFC is used for phone-to-vehicle authentication in CarKey, unless the car supports CarKey over Ultra Wideband, as is the case with the BMW Digital Key Plus. To enable the BMW Digital Key, the iPhone must be placed in the car's wireless charging tray, enabling communication with the vehicle. This process is reminiscent of how a phone must be in proximity to a credit card reader for grocery payments.
