WIFI and Bluetooth
In Wi-Fi connections, the Xiaomi Mi Box S TV-Box has a Wifi ac 2.4/5GHz with Bluetooth 4.2 with which we connect to an ASUS RT-AC1200G+ Router, a mid-range device. We perform tests on the use of streaming using the iPerf measurement tool to see the maximum performance of each network adapter.
- Wifi speed results: Correct speed for this wifi adapter, quite stable.
- Wifi range: At a distance of 5 meters with a wall we have a signal of 41 dBm, correct values.
- Bluetooth: We can connect compatible devices without problems.
- We recommend reading our Tutorial SAMBA on Android networks if we are going to use files from our network PC.
Power consumption, temperature and noise
The Xiaomi Mi Box S TV-box using the SoC Amlogic S905X-H has correct results in terms of consumption. We are in front of a SoC of low consumption and the hardware don’t heat much when using it with classic apps like Youtube or browsers.
We check the performance of the TV-Box in scenarios of maximum sustained performance and in its usual use, we use a stress app for fifteen minutes and thermal camera to detect hot areas. As we have seen the Xiaomi Mi Box S does not have ventilation slots but the heat sink system works perfectly.
- Loss of performance: The system maintains a maximum constant performance, there is no loss of performance.
- Temperature: The upper part heats up a little but does not affect the general use of the TV-Box.
- Noise: Fanless system, 0db.
PERFORMANCE TEST
SOC
At the performance level the Xiaomi Mi Box S has acceptable results in the line of Amlogic S905X-H (detects as S905L) Quad Core Cortex-A53 SoC, in the graphical section the power of the Mali-450 MP5 GPU is enough to move most games or Android apps, where this SoC suffers is in the high load 3D Games. If we compare the results we can see how it falls below the powerful SoC Amlogic S912 and Amlogic RK3399 and is close to the RK3328, in general, correct results for this type of SoC
Benchmarks
Games and gamepads
In the gaming aspect the Xiaomi Mi Box S have the Amlogic S905X-H SoC that integrates a Mali-450MP5 GPU, this model allows us to correctly move most Android titles without performance problems and good compatibility.

Audio playback test
Testing the Xiaomi Mi Box S using a Yamaha RXV-577 AV receiver we check that they supports DD and DTS pass through sound. We can only listen to the multi-channel audio up to 5.1, if we do not have an AV receiver and we have problems to listen to files with AC3 or multichannel sound we must configure the system to listen to configure the system to listen to multichannel AC3 videos in stereo on any TV.
- Ports: HDMI up to 5.1 / stereo audio jack + optical multichannel by mini TOSLINK up to 5.1.
- Certification: DD y DTS 5.1.
- Chomecast Audio: We can use the Mi Box as an audio player using the app Google Home.

| Optical | OK | Core | Core | Core* |
- PCM – Stereo only doing downmix from DD or DTS
- Core – Only the core of the format is played back with what we passed to the Dolby / DTS base system
* Our AV receiver does not support these native formats but we verify that it is played back to 7.1
Streaming services
We pass the classic tests on streaming services to see how the most popular services work. In this model does not have certificates for these services. The Xiaomi Mi Box S model is undoubtedly one of the best official solutions to watch streaming services, we have all the necessary certificates and there are native apps that work on this hardware without problems. In the case of Netflix we can see the service at 4K 16000 kbps and 10 bpc which is the maximum possible quality.

Opinion
As we have been able to verify the new Xiaomi Mi Box S continues the line of the previous version, it is a very solid model that provides us small improvements compared to the previous version. The most notable improvement for daily use is the improvement in the reading speed of the internal storage, which is almost double and also now integrates a new WiFi aC adapter with Bluetooth 4.2 that is expected to solve certain incompatibilities that had some users with the previous chip. The overall design is quite the same and apart from a more square box something better thermally we have a remote that now has specific keys for Netflix, Live channels and multitasking.
The Xiaomi Mi Box S undoubtedly remains an excellent TV-Box for those looking to watch streaming payment services such as Netflix, Amazon Prime Video, HBO and others, you will have all the certificates by Google and will not have the slightest problem in seeing these emissions in the best quality available. You have the support of the brand Xiaomi via OTA (although the jump to Orea has been controversial) and the inclusion of Chromecast that allows us to use it even as an audio player point. In general a good official Android TV at a very tight price.

Can I use this device as an alternative to discontinued Google Chromecast Audio to stream music to my analog hi fi set up, connecting to my amp directly?
Hello, I would like to ask if I can playback 4k(2160p)/60fps movies vie my USB 2.0 on Mi Box S.
Yes, but depends of the bitrate and other aspects.
Good wifi have better speeds.
Any real movie in 4K@60? Just curious… the 99.999999999% is 24p.
Dera Kim,
Thank you for your fast the reply.
The reason i asking is because i had watched same review at the youtube for testing to playback vie usb same samples and the play with lag the uhd etc.
Also, one of the main i want to buy is i have a lot movie on my hdd 12 and 25 GB.
This is not the box for this files, go for a nvidia shield, realtek or himedia.
This soc can playback 4K60fps videos, but USB 2.0 is very limited interface and the compression methods be very varieds.
Your movies i am sure are 4K30fps.
Hi i have a 500 gig external that i would like to browse the content & watch my movies / series however it doesn’t seem to allow this ? It gives me an option to browse however when i try it reroutes me to either eject or format as a storage device.
You can read any disk, the problem is just write.
Please tell me how, because I have the same problem. I have a 2 Tb HDD with numerous old movies and series I would like to watch with the MI tv-box but somehow it doesn’t connect unless I format (delete all content on) my external HDD.
What format have this disk? Needs a external power source?
Is just connect and read with any files explorer like X-Plore.
how do i remove read only status on my external hdd?
Use the Android folder inside the external drive.
Check your explorer app and permissions.
Format your drive as internal storage.
the only good way is to format my external hdd as device storage? i allow all permissions for both chrome n torrent app but still shows read only
My Mi Box S can’t seem to play H264 10-bit on both MX Player and VLC. On MX Player it can’t use HW decoder at all.
Is this expected? If it is I feel like returning it, because a lot of my files are still on H264 10-bit.
If don’t work for you then return.
I checked your review once again, and it seems you changed H264 10bit category to ‘Frameskip’. Was it that way before or did you change it because of my comment?
Also I think it handles 10-bit HEVC pretty fine. Playback was smooth in VLC for both 4k and 1080p anime, although it only seems to skip a bit due to subtitles?
Which is the better box, TX6 (not mini) or Mi Box S?
Mi box S.
what is the take for mi s or mecool km3 ? i dont care about netflicks in full hd i just need a power pack and smooth performance on player and in games at the same in over all ui ? which sud be chosen ?
For games KM3, but better go for X96 Max, more roms and ethernet gigabit.
If you want games Android mobile is better than Android TV.
Is there somewhere that I can key in the 30 most frequent channels for ease and quick retrieval whenever I want to change channels?
It is very troublesome to switch channels from 05 to 866, clicking tediously all the ways. Then later want to watch channel 273, has to do many clicks downward, then to jump into channel 2713 more clicks upward. Any shortcut?
It is too tedious to search up and down many channels. Is there anyway to store say 20 most wanted to view channels in one area for quick and ease of retrieval?
it gives you free netflix?
Why?
Netflix is never free 🙂
So just to clarify, can we play both YouTube and Netflix at 4k resolution on the mi box 3 and mi box s?
Yes, as you can see in the streaming test section.
Amazing review but wanted to know one thing. Are we able to play high bitrate files. Like bluray movies via usb without any lag?
Hi thanks.
You need to calculate your files bitrate and the bitrate of the usb (see review).
Wifi can be faster with 5G.
Best regards.
That was a best review about Xiomi Mi Box S I have seen. I want to use this TV Box for commercial purpose and want to make a custom app to install in it. But I want to give voice commands to that app using the mic of remote control, Is there any way I can do that or is it simply not possible with this xiomi box S? Or Is it possible that I can configure some button of remote control that can open my app or send voice commands to my app just like the way Google Assistant… Read more »
Thank you so much for the detailed and excellent review.
Just bought 2 units to my client that need a 4k netflix playback device, Since Intel’s NUC J3455 based, Couldn’t play netflix 4K smoothly (non HDR).
Yes, in Xiaomi Mi Box 4K+HDR.
No, in Intel NUC with celeron/pentium processor only 4K in core models, but no HDR.
Best regards.
Why does the chart say “SD (480p) / 5.1” if it’s 4K HDR compatible?
Typo error, fixed.
HI:
You state that this BOX support DD+ on Optical (Core). How that is possible? Any special configuration? And also my Box tell on NETFLIX that 5.1 does not exist, and, according to my understanding that is because EDID of my TV say no. Also on Kodi I try to passtrought DD+ to a receiver that support DD+ trough Optical entry but nothing. Using a PEN he reads, Optical no.
Can you help on this?
Thanks
Carlos
Hi. Yes if you use KODI or MX Player, CORE = basic DD 5.1.
https://androidpctv.com/tutorial-basic-concepts-for-multichannel-audio-on-windows-and-android/
I don’t tested Netflix with optical output, users have a lot of problems with this as i understand. I will check in my setup later.
Hi. Thanks. Strange. On my device, LG BH6220S does not work with Kodi. I test some Demo Files with DD+ and not working. Just silence. I try for instance DTS-X and DTS-MA and was converted to DTD-5.1 DTS-TrueHD just PCM 2.0. Now, I wonder if my device can decode DD+ over Optical. Perhaps not. Or should be the Optical Cable?. Netflix as far as I understand try to find if the device supports 5.1 and if I am connected to a TV, Stereo, Netflix just send Stereo. On you Setup perhaps not because you have a connection over HDMI to… Read more »
