The new Apple C1 modem that powers the cellular connectivity of the iPhone 16e is the company’s first cellular modem designed in-house.
The C1 offers “fast and reliable connectivity, and it’s the most power-efficient modem ever in an iPhone,” said Kaiann Drance, Apple’s vice president of worldwide iPhone product marketing, in a launch video released Wednesday. Thanks to its efficiency — and an optimized internal design that allows for a bigger battery — the iPhone 16e offers an “unprecedented level of battery life in a 6.1 inch iPhone,” she added.
The Apple C1 integrates 4G, 5G, satellite and GPS radios in one chip. The C1 represents a brand-new direction for Apple silicon, alongside the company’s processors and other wireless chips. Recent Ookla speed tests suggest that the C1 modem holds its own against the Qualcomm chip in the iPhone 16, as detailed in this comparison.
