With the launch of the new iPhone 16, Apple has also launched a new MagSafe wireless charger to replace the old charger launched four years ago. The new wireless charger still adopts a circular charging board design, but with a braided wire body, which is more durable and distinguishes it from the old model.

The new wireless charger, paired with a 30W charger, can provide an output power of 25W and can charge iPhone 16 and iPhone 16 Pro to half capacity in 30 minutes, providing the same experience as wired fast charging.

The newly launched magnetic wireless charger by Apple continues the design of separating the power conversion circuit and wireless charging circuit in the old product, fundamentally separating the heat source and reducing temperature rise, thereby enhancing the consumer experience. The most significant improvement of the new magnetic wireless charger is the use of braided wire body, which avoids the cracking and breakage of traditional TPE outer skin, and has a longer service life.

Through disassembly, it is found that the new magnetic wireless charger has higher integration compared to the old wireless charger. It has a USB-C interface controller and a Texas Instruments power chip inside the USB-C plug. Two highly integrated chips from STMicroelectronics are used in the wireless charger, which integrates more functions and reduces the number of peripheral components compared to the old wireless charger.

The USB-C plug is protected by steel sleeve spot welding, with an internal PCBA module for power conversion and filled with thermal conductive adhesive to enhance heat dissipation performance. In wireless chargers, double-sided tape is also used to stick the PCBA module to the aluminum alloy shell, enhancing heat dissipation and reducing temperature rise. Thanks to the improvement in integration, the PCBA module area has significantly reduced, simplifying the internal layout design of the charger.
