Xiaomi isn’t done with its in-house chip experiment. According to a fresh leak, the company is already working on the Xiaomi 17S series a direct successor to the Xiaomi 15S Pro. The twist? It’s expected to run on Xiaomi’s second-generation XRing chipset, potentially arriving in 2026.

Xiaomi 17S series will likely feature the XRing O2 chipset

The leak, shared by known tipster Smart Pikachu, claims that Xiaomi is preparing the 17S series as a follow-up to this year’s 15S Pro. That device debuted as a mid-year refresh and stood out mainly for its use of the XRing O1 processor, ditching Qualcomm hardware entirely.

Now, Xiaomi appears ready to double down. The 17S lineup is expected to debut with the XRing O2 though the chip’s baseband is reportedly still in development.

Xiaomi continues to keep custom silicon locked to China

It’s unlikely the Xiaomi 17S series will launch outside China. Just like the 15S Pro, Xiaomi seems intent on keeping its in-house processors within its home market. That decision carves out a clear divide between domestic exclusives and global releases.

Globally, the Xiaomi 17 Ultra is expected to lead the brand’s premium lineup, powered by third-party silicon most likely Qualcomm’s Snapdragon flagship.

What to expect from Xiaomi’s XRing O2 chip:

• Built in-house as a follow-up to the XRing O1
• Baseband still in progress, pointing to a 2026 release
• Expected to debut first in the Xiaomi 17S series
• Likely focused on energy efficiency and tighter OS integration

Xiaomi 17S could stay quiet, but still matter

Even if the Xiaomi 17S series never leaves China, it matters. It signals that Xiaomi is serious about custom silicon and plans to keep pushing forward. The XRing O2 could eventually evolve into something more global, but for now, it’s fueling a product that’s shaping up to be quietly important.

In the background, Xiaomi is building its own path and the 17S may just be the next stepping stone.
