Apple has just revealed its debut custom 5G modem, named “C1”, which will first appear in the brand-new iPhone 16e. The C1 modem plays a key role in enhancing the iPhone 16e’s battery life, making it last longer than any other iPhone with a similar 6.1-inch screen, like the iPhone 15 or iPhone 16.
By integrating the advantages of Apple’s own silicon technology, the C1 modem stands out as both the first modem Apple made itself and the most energy-saving modem ever used in an iPhone, providing swift and dependable 5G service. The combination of Apple’s silicon, including the C1, the iPhone’s new internal layout, and the smart energy management of iOS 18, leads to an impressive battery performance.
It’s worth noting that the C1 modem is exclusive to the iPhone 16e; other iPhones still rely on modems from Qualcomm. This step is similar to when Apple switched from Intel processors to its own chips, showing Apple’s strategy to lessen its dependence on external suppliers like Qualcomm for crucial components.
