HyperOS 4 From Xiaomi: When the Update Will Reach Your Phone

Xiaomi has started rolling out stable HyperOS 4, built on Android 17: since October 15, flagships in China have been receiving it in stages. Below is the schedule for each model, plus what to expect if you live outside the Chinese market.

What has happened so far, and what it means for you

Xiaomi confirmed on its community forum that internal beta recruitment closed on October 14, and stable builds began reaching the first devices the very next day. For now, that applies to China only. The company hasn’t announced a stable timeline for the rest of the world, although the global beta program is already running.

The first wave: 12 devices

The first to get the update are every version of the Xiaomi 17 (Ultra, Ultra Satellite Edition, Pro Max, Pro, and the standard model), the foldable Xiaomi Mix Flip 2, four Redmi K90 models (Pro Max, Pro, Pro Lamborghini Edition, and the regular K90), and the Xiaomi Pad 8 and Pad 8 Pro tablets.

Does “China first” mean a long wait?

Not necessarily. Xiaomi’s international releases usually start a few weeks after the Chinese one, so a global wave could plausibly begin in late October or November. That’s an educated guess based on past years, not an official date.

The full schedule for phones and tablets

The table below follows Xiaomi’s schedule for China. We left out TVs, speakers, and smartwatches, since this article is about phones and tablets.

Why this schedule differs from what you may have read elsewhere

Some simplified write-ups claim that the Xiaomi 15 and Redmi K80 get the update in November, while the Xiaomi 14 and Redmi K70 wait until December. The real picture is more detailed: the Xiaomi 16 series gets it as early as the end of October, the Xiaomi 14 Ultra and Redmi K70 are in the November wave, and only the standard Xiaomi 14 has to wait for December. If your model is in the table, go by the table.

Who shouldn’t wait for the update

Some phones have already used up their guaranteed update allowance, and HyperOS 4 won’t reach them. These include the Xiaomi 12S Pro and the Redmi Note 12. For models that aren’t in the table, such as the POCO lineup, the Chinese schedule doesn’t apply, and you’ll need to watch for a future global timeline.

What’s interesting about HyperOS 4

After the update, a Xiaomi phone will look different: the interface turns translucent and glassy, and lock screen notifications fold into a tidy stack. Behind the new look sits a rebuilt voice assistant running on the company’s own language model, plus a system that loads your favorite apps into memory before you even open them. Here is what that changes in daily use.

The Soft Light Glass interface

The most visible change is the new visual style. Translucent layers, light refraction, and blur effects appear on the lock screen, home screen, icons, Control Center, folders, and widgets. There’s a catch, though: the full version of the effect needs powerful hardware. The deepest integration is aimed at phones with the Snapdragon 8 Elite, Dimensity 9500, Xring O1, or newer flagship chips. Other devices get the effect too, just in a simpler form.

A lock screen without the card clutter

Notifications now collapse into a vertical stack instead of separate cards that used to fill half the screen. The clock can be stretched, resized, and moved around. It’s a small thing, but it’s the kind of small thing we look at dozens of times a day.

Super XiaoAi 2.0 and the Inspiration Ball

The updated voice assistant runs on Xiaomi’s own MiMo V2.5 language model. It remembers context better, can carry out actions across apps, and understands what’s happening on your screen. A separate new feature, the Inspiration Ball, works much like Google’s Circle to Search. It analyzes what’s on screen and suggests what to do with it: plot a route on the map, create a calendar entry, or find a product to buy. You can, for example, point at a phone number and ask it to call.

Speed: what Xiaomi promises

The system uses AI to preload the things you use most into memory ahead of time. On top of that, the updated HyperCore engine cuts redundant CPU instructions by about 14.4% compared with HyperOS 3, and HDR photo processing now takes 240 ms instead of 310 ms. The company also claims lower memory demands and better battery life. These are the manufacturer’s claims, so firm conclusions will have to wait for independent tests.

Syncing two phones

If you own two Xiaomi devices, notifications can be mirrored from one to the other. The receiving phone must run HyperOS 4, while the sending phone can stay on HyperOS 3, so you don’t have to update both at once.

How to tell if the update has arrived

Open Settings, go to About phone, and tap the system version to check for updates. Menu placement may vary depending on your firmware version. The update arrives in waves, so even if your model is on the list, the notification may not show up right away.
