Apple is already testing the C2 modem for future iPhones Apfelpatient

Apple is continuously working on the further development of its hardware in order to become more independent of external suppliers. After the company has already developed its own processors for iPhones, iPads and Macs, the focus is now on mobile technology. The next step is its own 5G modem. As a well-known leaker reports, Apple is already testing the second generation C2 modem. It is said to be faster and more efficient than its predecessor and may be used in future iPhone models.

Apple has confirmed that development of new iPhone chips begins several years before their market launch. So it's not surprising that the company is working on a new modem. It has long been known that Apple wants to move away from Qualcomm as a modem supplier. Starting to develop in-house is a complex and lengthy process. Apple has taken a first step with the C1 modem, but the second generation is intended to further optimize the system. Now there is new evidence that Apple is already testing the C2 modem internally.

Apple tests the C2 modem with the identifier C4020

A private account on the X platform, which has published detailed information about Apple hardware several times in the past, reports that Apple is currently testing the C2 modem. Internally, the modem is said to be called C4020. This confirms that the development of its own cellular modem is further advanced. No specific technical details or performance data have been given so far. Apple is, as usual, reticent to provide official information about future products. But past statements by Apple's chip chief Johny Srouji indicate that the company has big plans for modem development. He explainedthat the C1 modem is just the beginning and that further advances can be expected with the next generation.

What is known about the C1 modem?

Apple's first in-house modem, the C1, is already used in the iPhone 16e. Apple calls it the most efficient iPhone modem ever. It is said to be a key factor in the iPhone 16e offering the longest battery life of any 6.1-inch iPhone - including the more expensive iPhone 16 models, which continue to use a Qualcomm modem. There are no independent tests of the speed of the C1 modem yet. However, it is expected to be slower than Qualcomm's current Snapdragon X75, which is used in the more powerful iPhones. Developing a competitive 5G modem is technically challenging, so it would not be surprising if Apple cannot match Qualcomm's performance with the first generation.

What improvements could the C2 modem offer?

With the C2 modem, Apple could improve some of the current weaknesses. These include higher speed, a more stable connection and even lower energy consumption. The integration of an in-house modem could also lead to the entire system being better coordinated with Apple processors and software. The possible advantages of an advanced Apple modem would be:

Faster 5G connections: Higher transfer speeds could result in faster downloads and a more stable network connection.
Better energy efficiency: The C1 modem is already considered to be very energy efficient. The C2 modem could further expand this advantage and thus ensure an even longer battery life.
Optimized integration with Apple hardware: Apple develops both the processors and the software for its devices. A proprietary modem could be better tailored to these components in the future, which would have a positive effect on overall performance.

Why does Apple develop its own modems?

In recent years, Apple has pursued a strategy of becoming less dependent on external chip suppliers. This is particularly evident in the development of its own processors. After Apple successfully replaced Intel chips in Macs with its own M processors, the next focus is on mobile technology. The most important reason for in-house development is full control over the hardware and software. Apple can adapt the modem perfectly to the iPhone operating system and the in-house chips. In the long term, this could not only improve performance, but also reduce costs. Another factor is the dependence on Qualcomm. Apple has argued with the chip manufacturer several times in the past about licensing fees. An in-house modem could free Apple from these conflicts in the future.

When could the C2 modem appear in iPhones?

There is no official information about the market launch of the C2 modem. Since the C1 modem is only in the first devices, it is unlikely that Apple will use the new modem in the next iPhone. It is more likely that Apple will further develop and optimize the technology in the next one to two years before it is installed across the board in new models. The development of its own 5G modem is a big step for Apple. While the C1 modem can still be seen as a first test run, the C2 modem could show whether Apple can keep up with the established competition.

Faster, more efficient, more independent: What the Apple C2 modem could bring

Apple is already testing its C2 modem, which is intended as the successor to the current C1 modem for future iPhone generations. Developing its own modem is an important step for the company to break away from Qualcomm and further expand its control over the hardware. So far there is little official information on the technical improvements. But it is to be expected that the C2 modem will offer a faster connection and even better energy efficiency. In the long term, Apple is relying on its own production of chips and modems to further optimize the iPhone ecosystem. It remains to be seen when the new second-generation modem will actually be installed in iPhones and whether it can keep up with the current Qualcomm alternatives. (Photo by Unsplash+ / Getty Images)
