Apple’s C1 modem inside iPhone 17 Air will be slower on some carriers

Apple has spent years developing its own mobile data modem to replace Qualcomm’s, which it has long depended on. The first Apple-designed modem, the C1 chip, debuted in the iPhone 16e and is expected to power the upcoming iPhone 17 Air. Performance comparisons with Qualcomm’s latest chip have been mixed, but a new Ookla study offers the most detailed analysis yet.

Ben Lovejoy for 9to5Mac:

Comparing the performance achieved by the iPhone 16, which uses Qualcomm’s chip, with the iPhone 16e, which uses Apple’s own C1 chip, the company was see how each modem fared.

Ookla’s first study, published back in March, showed that the C1 chip beat Qualcomm in a number of key areas. That one showed that the C1 was better in areas of poor mobile coverage, but Qualcomm came out significantly ahead when it came to the areas with the fastest connections.

Performance doesn’t just depend on the chip, but also on the network on which it is used. That’s because different networks support different chip features, as noted in Ookla’s latest study.

For example, carrier aggregation is a technique used to combine different frequencies into a single mobile data connection so as to maximise the total bandwidth achieved. Qualcomm supports aggregation across four carriers, while the C1 modem only supports three. So if you’re on T-Mobile, then having a Qualcomm modem is an advantage.


MacDailyNews Take: For an iPhone, we’d much rather have a connected iPhone in poor coverage areas than a slightly faster connection in specific conditions.

  1. Tim Cook would rather give you subpar performance than use state-of-the-art Qualcomm modems.
    The same was true with Intel processors. Cook never used the best Intel processors, instead choosing to cheap out on second-best processors to maximize his profits over performance.
    Fire Tim Cook!

    1. Yes, agree that you are clueless.

      But so it Cook.

      Jobs was trying to find a way to own all critical technologies and not be dependent on the likes of Qualcomm. That is why he buried Flash as well, and that is why he sought his own processors so Intel (and before that Motorola) could not make Apple dance to its tune.

      Now the modem is all theirs. But you did not read the article did you. It said it OUTPERFORMED Qualcomm in many areas, but you never learned to read did you?

      Now AI is the next critical technology Apple MUST figure out in its own way and not cave to someone else. I suppose you want Apple to go back to Intel processors, OS9, Qualcomm modems, and maybe even start adopting Flash, idiot.
