The Xiaomi Mi Box S 4K is a small device that connects to your TV via HDMI. It transforms any television – even older ones – into a complete Smart TV. With it, you can access Netflix, YouTube, Amazon Prime Video, and dozens of other streaming apps.
The device runs Android TV, Google’s operating system designed specifically for televisions. This means you have access to the Google Play Store and can download the same apps you would use on an Android phone, but on the big screen in your living room.
The key difference lies in the price. While a 4K Smart TV costs between R$1,500 and R$5,000, the Mi Box S goes for around R$350 to R$400. For those who have a TV that works well but lacks smart features, this represents a significant saving.
How the Mi Box S Works in Practice
Installation is simple: you connect the device to the TV’s HDMI input, plug the power cable into the wall socket, and connect to the internet (via Wi-Fi or Ethernet cable). In less than five minutes, everything is up and running.
The remote comes with shortcut buttons for Netflix and Amazon Prime Video. There’s also a button to activate Google Assistant by voice. You can say “show action movies” or “open YouTube” and the system responds instantly.
The interface is clean and organized. The home screen displays content recommendations from your favorite apps, all in one place. There’s no need to switch between apps to find what to watch.
Why This Device Makes a Difference in People’s Lives
Real Economy
Many families have TVs that work perfectly, but aren’t smart TVs. Replacing them with a new one just to have Netflix would be a waste. The Mi Box S solves this problem for less than 10% of the price of a new TV.
Digital Accessibility
In a world where streaming is the primary way to consume entertainment, being left out means missing out on series, movies, and educational content. The Mi Box S democratizes this access at an affordable price.
Voice Control
For people with mobility issues or seniors who find the controls too complex, Google Assistant’s voice command greatly simplifies the experience. Just say what you want to watch.
Technical Specifications That Matter
The Xiaomi Mi Box S offers 4K Ultra HD resolution with HDR (High Dynamic Range) support. This means sharper images and more vibrant colors – provided your TV also has these technologies.
The 2GB of RAM and 8GB of storage are sufficient for daily use. It’s not a device for heavy gaming, but it runs streaming apps smoothly.
The audio supports Dolby Digital and DTS, formats that deliver cinematic-quality sound when connected to a soundbar or home theater system.
5 Reasons to Consider the Mi Box S 4K
- Unbeatable value for moneyFor less than R$400, you get access to virtually everything a Smart TV offers.
- Constant updatesBecause it uses Android TV, the system receives security updates and new features regularly.
- VersatilityIt works on any TV with an HDMI input, whether it’s an old CRT TV or a more recent model.
- Chromecast built-inYou can mirror your phone screen on your TV or send videos directly from apps.
- Giant app libraryThe Google Play Store has thousands of compatible apps, ranging from lightweight games to fitness apps.
Limitations You Need to Know
Not everything is perfect. The Mi Box S has 8GB of storage, and the operating system already takes up some of that. That leaves about 5GB for apps. For those who install many apps or games, space can become limited.
The interface, while functional, may feel slow at times, especially when navigating between many open applications. It’s nothing that prevents usability, but users accustomed to very fast devices might notice.
Some specific streaming services, such as Apple TV+, may not have a native app available. In these cases, it’s possible to use Chromecast to stream from your mobile phone.

FAQ – Frequently Asked Questions
Does the Mi Box S work on older TVs without HDMI? Not directly. You need an HDMI input. For very old TVs (with only RCA), you would need an HDMI to RCA adapter, but the image quality would be limited.
Do you need fast internet to use it? For 4K streaming, ideally you should have a connection of at least 25 Mbps. For Full HD content, 10 Mbps is sufficient. SD content works with slower connections.
Can I play games on the Mi Box S? Yes, but with limitations. Light games from the Play Store work well. Heavy, next-gen games don’t run properly due to the simpler hardware.
Is the remote control included? Yes, the Bluetooth remote control comes in the box, along with batteries. You can also use your phone as a remote control via the Google TV app.
Does it work with any Wi-Fi router? It works with 2.4GHz and 5GHz Wi-Fi networks. The 5GHz connection offers better stability but has a shorter range.
Can I use it on more than one TV? The device works on any TV, but you need to disconnect it from one to use it on another. It does not transmit to multiple TVs simultaneously.
Is it possible to expand the storage? Yes, via USB port. You can connect a flash drive or external hard drive to store more applications or media files.
How much energy does it consume? Power consumption is very low, around 5W under normal use. It practically doesn’t affect your electricity bill.
