The Xiaomi TV Box S 3rd Gen is a small 4K streaming box that runs Google TV.
It plugs into your TV’s HDMI port and gives you Netflix, YouTube, Disney+, and other apps.
If you want to buy Xiaomi TV Box S 3rd Gen for a TV that feels slow or outdated, this guide shows what it offers and where it falls short.
Xiaomi TV Box S 3rd Gen overview
This is a streaming box, not a stick. It sits next to your TV, connects with an HDMI cable, and adds Google TV to any TV with an HDMI port.
Its job is simple: make an older TV smarter. That is the main reason to buy Xiaomi TV Box S 3rd Gen.
Xiaomi built it around 4K video. The listing says it outputs 4K at 60 frames per second and supports Dolby Vision and HDR10+. Inside are 2GB of RAM and 32GB of storage for apps.
A quick note on how this review works. Everything here comes from the product details on the Amazon listing. We did not test the box ourselves, so you will not find claims about real-world speed or picture tests. Where the listing is unclear, we say so.

One thing to check. The Amazon product title mentions Wi-Fi 6 and Dolby Atmos. The feature list only names dual-band Wi-Fi and Dolby Audio. We could not confirm Wi-Fi 6 or Atmos from the details we have, so read the listing again if either one matters to you. Do that before you buy Xiaomi TV Box S 3rd Gen.
Design and build
The box is small. It measures about 95 mm square and 16.7 mm thick, and it weighs 91.2 grams. That is roughly the size of a coaster, so it should hide easily behind or beside a TV. That helps if you buy Xiaomi TV Box S 3rd Gen for a crowded TV stand.
The color is black. You get one voice remote with the box. The listing names an HDMI 2.1 port and a USB 2.0 port. It does not say how the remote feels or what the box is made of, so we can’t comment on build quality.
The box needs its own power adapter, which is included. Plan for a free wall outlet near the TV. An Ethernet port is not listed, so this box seems to rely on Wi-Fi.
Picture and streaming quality
The listing says the box outputs 4K at 60 frames per second. It also supports Dolby Vision and HDR10+. These are HDR formats. They aim to give brighter highlights and deeper dark areas. Your TV must support the same formats, and the show or movie must be made in them.
For video decoding, the listing names H.265/HEVC and VP9. Both are common for 4K streaming. AV1 is not listed, and we could not verify support for it.
On sound, the listing names Dolby Audio and DTS:X. You need a compatible TV, soundbar, or receiver to hear the full effect.
AMD FreeSync also appears under special features. The listing does not explain how it works on this box, so treat it as a bonus and not a reason to buy.
We have no tests of actual picture quality. What we can say is that the specs match what a modern 4K TV expects.
Google TV experience
Google TV is the software on the box. It puts your streaming apps on one home screen and suggests things to watch. That is a general description of the platform, not something specific to this box.
The listing says you can use thousands of apps, and it names Netflix, YouTube, and Disney+. It also lists voice control through Google Assistant. The included remote has voice support, so you can speak a search instead of typing it with arrows.
Google Cast is listed too. That lets you send video or mirror your phone screen to the TV. It is a plus if you buy Xiaomi TV Box S 3rd Gen and already use a phone or tablet at home.
Searching xiaomi tv box s 3rd gen buy because of one niche app? Check that the app exists in the Google TV store first. Big services are usually there, but smaller ones can be missing.
Performance
The box has a quad-core CPU that runs up to 2.5GHz, plus an ARM G310 V2 GPU and 2GB of RAM. The listing says this is enough for smooth menus and multitasking. We could not test that claim.
Two gigabytes of RAM is on the lower side. Streaming apps should be fine. Heavy games or many apps open at once are harder to judge from a spec sheet.
The 32GB of storage is a decent size for a streaming box. You can install many apps before space becomes a worry. Some of that space is used by the system itself.
For Wi-Fi, the box has dual-band support. The 5GHz band is usually faster and works better for 4K if your router is close. Bluetooth 5.2 lets you pair some wireless accessories. HDMI 2.1 covers 4K at 60 frames per second.
For basic streaming, the specs look reasonable if you buy Xiaomi TV Box S 3rd Gen. Real speed is something we could not test.
Pros and cons

- Supports 4K at 60 fps with Dolby Vision and HDR10+.
- Runs Google TV with Google Assistant on the remote.
- Comes with 32GB of storage.
- Small and light at 91.2 grams.
- Includes the remote, power adapter, and HDMI cable.

Who should buy Xiaomi TV Box S 3rd Gen?
This box makes the most sense for people with a 4K TV that has weak or outdated smart features. If your TV’s built-in apps are slow, a separate box is a simple fix.
It also suits anyone who likes Google’s ecosystem. If you already use Google Assistant or cast from your phone, the setup will feel familiar.
A small second TV is another good fit. The box is tiny, and it includes everything you need to start.
If you plan to buy Xiaomi TV Box S 3rd Gen for a Dolby Vision TV, the listed HDR support is a clear plus.
Who may want to skip it?
This box is not for everyone, even if you already want to buy Xiaomi TV Box S 3rd Gen.
Skip it if your TV is 1080p. The 4K features would go unused, and a cheaper device may do the job.
Skip it if you need a wired connection. With no Ethernet port listed, a weak Wi-Fi signal could be a problem.
Heavy gamers or people who run many apps at once may want more RAM. Some buyers also prefer Fire TV, Roku, or Apple TV because they already know those menus.
And if clear warranty terms matter to you, note that the listing points you to the seller.
