HyperOS 4 beta update 2026: Xiaomi’s full first-wave device list

Introduction

Xiaomi’s HyperOS 4 beta update is one of those releases that immediately makes people check one thing first: am I in the first wave? And honestly, that’s the right instinct. The rollout starts on August 14, 2026 in China, and the first devices lined up are the Xiaomi 17, Redmi K90, and Pad 8 series. So, if you’ve been waiting to see where your phone or tablet lands, this is the part that matters most.

What makes this announcement a little more interesting than a normal beta schedule is that Xiaomi isn’t just talking about availability. It’s tying HyperOS 4 to real performance claims too — speed, stability, memory behavior, and a handful of AI changes that sound more useful than decorative. Here’s the thing: beta updates are often about testing, but they also give you the clearest early look at where a company thinks its best hardware stands.

Which Xiaomi, Redmi, and Pad devices get the first HyperOS 4 beta waves

The rollout is split into three dated phases, and that structure tells you a lot. Xiaomi isn’t dropping HyperOS 4 beta onto every eligible device at once. Instead, it’s spreading the test build across August 14, August 27, and September 17, 2026. That kind of phased rollout is pretty normal for big software releases, but it also means the first names on the list get the bragging rights.

And yes, those names are exactly what people scan for first. If you’re watching for a HyperOS 4 beta update, the device order matters just as much as the date. The first batch includes Xiaomi 17 models, Redmi K90 models, and the Pad 8 line, while later waves broaden the circle to older flagships, more tablets, and even foldables. That tells you Xiaomi is testing both its newest premium hardware and a wider set of devices before a broader release.

August 14, 2026: the first eight devices

The opening wave is tight and focused. It begins in China only, and it’s limited to eight devices. That usually means Xiaomi wants to start with its most controlled test group before expanding to more models. If you own one of these, you’re basically at the front of the line for Android 17 testing under HyperOS 4.

• Xiaomi 17
• Xiaomi 17 Pro
• Xiaomi 17 Pro Max
• Xiaomi 17 Ultra
• Redmi K90 Pro Max
• Redmi K90
• Xiaomi Pad 8
• Xiaomi Pad 8 Pro

That first wave is also a pretty clear signal about Xiaomi’s priorities. New flagships go first, then the newest Redmi premium models, then tablets. Nothing surprising there, but it does confirm the company is treating the launch as a serious early validation phase rather than a small publicity event.

August 27, 2026: the second wave is much broader

The second phase opens things up quite a bit. It brings in the Xiaomi 17T and 17T Pro, adds the Xiaomi 17 Max, and then fills out the list with several Xiaomi 15 family devices. That’s where the rollout starts to feel less like a boutique test and more like a real ecosystem push. It also adds the Redmi K90 Max, Redmi K90 Ultra, and Redmi K Pad 2, which shows Xiaomi isn’t limiting this wave to just one product category.

There’s one small detail worth noting here: the Xiaomi 17 Max is the only model in the source tied to a price, listed as 12/256GB and currently $759.21 on TradingShenzhen. That doesn’t change the beta schedule, of course, but it does show how closely people track these devices when rollout news drops. A phone can be in a beta list, but that doesn’t stop it from being part of the bigger purchase conversation too.

• Xiaomi 17T
• Xiaomi 17T Pro
• Xiaomi 17 Max (12/256GB, curr. $759.21 on TradingShenzhen)
• Xiaomi 15
• Xiaomi 15 Pro
• Xiaomi 15S Pro
• Xiaomi 15 Ultra
• Redmi K90 Max
• Redmi K90 Ultra
• Redmi K Pad 2

So, if you were wondering whether Xiaomi was only prioritizing its absolute newest phones, the answer is no. This second wave proves the company is also paying attention to still-relevant flagship generations and a wider tablet audience. That makes the beta feel more like a staged ecosystem rollout than a simple launch-day teaser.

September 17, 2026: the last first-batch rollout

The third and final first-batch phase wraps up the initial schedule. This is the list that makes the beta program feel broader than it first appears, because it includes foldables, Redmi K80 models, and two higher-end Xiaomi tablets. In other words, Xiaomi isn’t treating HyperOS 4 as a phone-only story. Tablets and foldables are clearly part of the plan too.

For a lot of readers, this is probably the most reassuring wave. It means the beta isn’t just centered around a tiny circle of flagship devices. Instead, Xiaomi is spreading the test across different product types, which is usually a good sign that the company wants to see how the software behaves in different usage patterns.

• Xiaomi Mix Flip 2
• Redmi K80
• Redmi K80 Pro
• Redmi K80 Ultra
• Redmi K100 Pro Max
• Redmi K100 Pro
• Xiaomi Pad 7S Pro 12.5
• Xiaomi Pad 7 Ultra

What HyperOS 4 says it will improve: speed, stability, memory, and AI

Xiaomi is clearly trying to frame HyperOS 4 as more than a skin refresh. The message is performance first, and that’s usually what people want to hear anyway. Nobody gets excited about a software update just because the settings menu moved around. What they want is for the phone to feel quicker, smoother, and less annoying in daily use.

That’s where the numbers stand out. Xiaomi is claiming up to 17.5% faster response time, 28.9% better app stability, and improved memory performance. Those are specific claims, not vague marketing fluff, and that makes them easier to judge later. If the update really delivers on even part of that, users should notice it in ordinary stuff like opening apps, switching between tasks, and keeping everything running without hiccups.

The performance claims are specific, not vague

The nice thing about having percentages is that you can at least understand what the company is aiming for. A faster response time should mean less waiting when you tap something. Better app stability should mean fewer crashes or weird slowdowns. Improved memory performance usually helps multitasking, especially on devices that juggle a lot of apps in the background.

That table is the simple version, really. The claims all point in the same direction: Xiaomi wants HyperOS 4 to feel less like “new software” and more like “the phone finally behaves the way it should.” And if you’ve ever used a device that gets just a little too sluggish after a few months, you know why that matters.

The AI and design changes are meant to be obvious in use

Performance isn’t the only story, though. Xiaomi is also talking about a new AI interaction feature and integration with Xiaomi MiMo large model, which makes it sound like the company wants HyperOS 4 to feel smarter, not just faster. That matters because a lot of updates promise intelligence without actually changing the way you use the device. Here, Xiaomi seems to be aiming for something a little more visible.

There’s also a design angle. The interface is said to have designs similar to iOS 26, and early videos suggest animations feel smoother than HyperOS 3. Now, that doesn’t automatically mean everything will look the same in daily use, but it does suggest Xiaomi is leaning into a cleaner, more fluid style. In practice, that kind of polish can matter just as much as raw speed because it changes how the whole phone feels in your hand.

Look, a software update can be technically impressive and still feel boring. But when performance, AI, and motion design all improve together, people usually notice. That’s the sweet spot Xiaomi seems to be aiming for with HyperOS 4.

What we know, and still don’t know, about the HyperOS 4 global rollout

Right now, the confirmed schedule is still China-only. Xiaomi hasn’t published the global timeline yet, so anyone outside China is working from expectation rather than official timing. That said, the source does suggest the international rollout should begin shortly after the China program starts, which is at least enough to give global users some hope instead of total silence.

That uncertainty is pretty common with major software releases. Companies often test first in one market, watch for bugs and feedback, then widen the rollout. So if you’re outside China, the safest reading is simple: the same device families may be among the first to get HyperOS 4 globally, but that’s still not something Xiaomi has formally confirmed.

In other words, the current rollout map is useful, but it’s not the final map. It tells us Xiaomi’s priorities, not the entire story. And that distinction matters more than people sometimes realize, because beta schedules can shift once real-world testing starts uncovering issues.

FAQ

These are the questions people usually ask once they see the rollout dates, device list, and performance claims side by side. So, let’s keep the answers straightforward.

Q: When does the HyperOS 4 beta program start?

It starts on August 14, 2026, in China. That first wave is the opening test stage for the Android 17 update.

Q: Which phones get the Xiaomi 17 beta update first?

The first batch includes Xiaomi 17, Xiaomi 17 Pro, Xiaomi 17 Pro Max, and Xiaomi 17 Ultra. Xiaomi 17 is right at the front of the rollout.

Q: Will the HyperOS 4 beta program come to global devices?

Yes, but Xiaomi hasn’t confirmed the timeline yet. The current expectation is that the global rollout will follow shortly after the China launch.

Q: What is new in HyperOS 4 besides the beta schedule?

Xiaomi is promising up to 17.5% faster response time, 28.9% better stability, improved memory performance, new AI interaction features, and Xiaomi MiMo large model integration.

Conclusion

HyperOS 4 beta update is shaping up as a performance-led release, with a staged rollout that begins on August 14, 2026 and stretches through September 17, 2026 in China. That alone makes it worth watching, especially if you’re the kind of person who likes knowing where your device sits in the queue before the public build ever arrives.

The real signal here is the device order. Xiaomi’s newest flagships lead the way, then the rollout opens up to older premium phones, tablets, and foldables. That’s a pretty clear hint that Xiaomi wants HyperOS 4 to be seen as a broad platform update, not just a small beta for its freshest hardware. And with the global rollout still unconfirmed, the safest move is to watch the China schedule closely and wait for the international details to catch up.
