Apple's modem gamble pays off: c1x nears qualcomm performance

For years, smartphone enthusiasts have fixated on processing power and camera megapixels. But the unsung hero of connectivity – the modem – is finally getting its due. Apple’s long-term effort to shed its reliance on Qualcomm for modems is showing tangible results, according to recent Ookla testing.

Apple's c1x modem surpasses qualcomm in key tests

The shift began with the introduction of Apple’s own C1 modem in the iPhone 16e. While the initial C1 lagged behind Qualcomm’s offerings, the subsequent C1X, debuting in the iPhone Air (September 2025), demonstrated a significant leap forward. The iPhone 17, 17 Pro, and 17 Pro Max then adopted the C1X, marking a clear commitment from Apple.

Ookla's speed tests reveal that the C1X has largely closed the performance gap with Qualcomm's X80 modem. While not quite matching the X80's peak speeds in every scenario, the C1X provides a noticeably improved experience, especially during peak network congestion. This improvement is particularly pronounced in regions like the US, UAE, Saudi Arabia, China, Sweden, Singapore, and Japan, where the modem handles mid-band 5G more efficiently.

Interestingly, the iPhone Air, powered by the C1X, actually outperformed the iPhone 17 Pro Max in latency tests across most markets. This suggests a more streamlined integration between Apple’s modem and processor, resulting in quicker response times. The median results reflect the typical user experience – normal network congestion and average signal strength – making the C1X’s improvements directly relevant to daily use.

However, the C1X didn’t show the same gains in markets like Brazil, India, and Malaysia, which rely more heavily on low-band 5G or experience greater network congestion. This highlights the modem's performance is heavily influenced by the underlying network infrastructure.

The implications extend beyond this generation. Apple is reportedly developing its C2 modem for the iPhone 18 Pro, signaling a continued push for greater autonomy in its supply chain. This move could mark a more decisive break from Qualcomm in the years to come.

The iPhone 17e's improved connectivity could be a compelling reason to upgrade in the US, especially for users frequently encountering slower speeds. Apple's dedication to its own modem Technology suggests a future where the company exerts greater control over the user experience—and perhaps, its own destiny.
