The HyperOS 4 rollout started on November 3, 2026, and it brings Android 17 to Xiaomi, Redmi and Poco phones in three waves. Newer flagships go first, and older budget phones wait until December. If your phone is in the first batch, you can already check for it.
Here are the facts you need in ten seconds.
- Start date: November 3, 2026, with later waves in mid-November and December.
- Based on Android 17, with a new glass-style look.
- Xiaomi 17, Xiaomi 15 and many Redmi Note and Poco models are in batch 1.
- Xiaomi claims app launches get up to about 20% faster after a day of use.
Updates arrive in waves, so not seeing it today does not mean your phone is left out.
Which phones get the HyperOS 4 rollout first?
According to 9to5Google, Xiaomi has confirmed three batches. The table below sums up the main groups.
| Batch | Timing | Main phones and tablets |
|---|---|---|
| 1 | From November 3, 2026 | Xiaomi 17 and 17T series, Xiaomi 15, Xiaomi Pad 8, Poco F8, X8 and M8, Redmi Note 17 and Note 15 |
| 2 | Mid-November 2026 | Xiaomi 15T series, Xiaomi Pad 7 and Pad Mini, Redmi Pad 2, Poco F9, F7 and X7 |
| 3 | December 2026 | Xiaomi MIX Flip, Xiaomi 14 and 13 series, Redmi Note 14, Poco F6 and X6 Pro, plus older budget models |
The same report notes that a few models, such as the Redmi 15 series and Poco X7, appear in more than one batch. Treat their timing as unconfirmed until Xiaomi clarifies.
Xiaomi has not said which regions get each wave, so your country may see it a few days later than another.
What changes after the update?
The biggest change is the look. Xiaomi describes a glass-inspired redesign, and Notebookcheck called it “Soft Light Glass” during the beta in September.
Beyond looks, the update adds a few practical things you will notice quickly.
- More lock screen options, including large clocks.
- New ways to organize your home screen.
- Better floating windows and screen orientation handling.
- A background AI feature that learns which apps you use and speeds up their launch.
The 20% speed figure is Xiaomi’s own claim. Independent tests have not confirmed it yet, so judge it on your own phone after a few days.
How to check for the HyperOS 4 update on your phone
Open Settings, go to About phone, and tap the HyperOS version card to check for updates. Menu names can differ slightly between phones.
Before you install, do these three things:
- Back up your photos, chats and files.
- Charge the phone to at least 50%, and use Wi-Fi.
- Free up some storage, since large updates need room to unpack.
Skipping the backup is the most common mistake. A big OS jump rarely fails, but when it does, a backup saves your day.
Why you may not see it yet
Phased rollouts reach a small share of users first, then widen. That is normal, and it lets the company pause if a bug shows up.
Android updates also tend to spread slowly across the whole ecosystem. We covered this in our look at why Android 17 adoption is stuck at 1%, and the Samsung side in our One UI 9 rollout guide.
Some outlets, like Android Headlines, suggest checking again over the next few days. That is sensible advice.
What to do if your phone feels off after updating
A phone often feels slower for the first day or two after a big update. Apps re-optimize in the background, and the new AI feature is still learning your habits.
Give it a day of normal use and leave it plugged in overnight once. Then restart the phone, and update your apps from the Play Store or GetApps, since old app versions can misbehave on a new Android release.
If battery drain or lag continues after three or four days, report it in the Xiaomi Community app. Early feedback is how bugs get fixed in later patches.
Frequently Asked Questions
Is HyperOS 4 based on Android 17?
Yes. HyperOS 4 is Xiaomi’s version built on Android 17, and it arrives on Xiaomi, Redmi and Poco phones.
When does my Xiaomi phone get HyperOS 4?
Batch 1 started November 3, batch 2 comes in mid-November, and batch 3 follows in December. Find your model in the table above.
Can I go back to the old version after updating?
Rolling back is hard. Notebookcheck says beta builds could not be rolled back over the air, so expect the same caution with stable builds and back up first.
Does the update cost anything?
No. It is a free over-the-air update, and you only need Wi-Fi and some free storage.
Should you install it right away?
If your phone is in batch 1 and you have a backup, go ahead, because a phone this recent should handle the update well. If you rely on your phone for work, wait a week and read what other owners report. Either way, do not hunt for unofficial files to jump the queue, since waiting a few days costs far less than a bad flash.
