These third-party accessories typically work by adding a thin receiver coil to the back of the iPhone 4, which can then be charged wirelessly using a Qi-compatible charging pad. While these accessories can provide a convenient and cable-free charging experience, they may not be as seamless or efficient as native wireless charging support.
How does wireless charging work on the iPhone 4 with third-party accessories?
Wireless charging on the iPhone 4 with third-party accessories works by using the Qi (pronounced “chee”) wireless charging standard. Qi is an open standard for wireless charging that uses electromagnetic induction to transfer energy between a transmitter (the charging pad) and a receiver (the coil in the iPhone 4 case).
When the iPhone 4 is placed on a Qi-compatible charging pad, the transmitter in the pad detects the receiver coil in the case and begins to transmit energy wirelessly. The receiver coil in the case then converts this energy into an electrical current, which is used to charge the iPhone 4’s battery. This process is safe, efficient, and convenient, but may not be as fast as wired charging.
Are there any risks or safety concerns with using wireless charging on the iPhone 4?
