HARDWARE TESTS

Storage and RAM Memory

We perform our usual memory tests and internal storage in the Xiaomi Mi Box S using the SD bench app. The results are better in reading than in the previous Xiaomi Mi Box, something that we can see in the loading speed of the apps. Storage can be expanded using the USB port from Settings> Storage> USB.

• Storage: Total 8GB – Free 3.8GB. / Is expandable with a USB memory stick
• RAM: Total 2GB – Free 1GB / DDR3L.
• Compatible formats: NTFS compatible / exFAT compatible

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. The games with a lot of 3D load are the ones that have frames drops in this GPU, so it is better to limit yourself to basic titles with little 3D load.

• Compatibility: Is NO possible to play demanding titles such as PUBG.
• Controls: Compatible with Gamepads by cable or bluetooth.

VIDEO AND AUDIO TEST

Video and audio connections

In terms of multimedia playback, the Xiaomi Mi Box S behaves perfectly using the Amlogic S905X-H SoC, a product that supports video output by HDMI 2.0a, which allows maximum resolution up to 4K@60fps with HDR information. We also have TOSLINK mini optical audio output that we can convert into SPDIF by the audio jack. This model is certified by Google and has support for Chromecast integrated.

Video playback test

We pass our video playback tests on the Android TV-Box Xiaomi Mi Box S, a model that has the S905X-H SoC that integrates a VPU compatible with most modern video formats as we can see in the results. By default this TV-Box brings KODI in KDMC version infested with streamings plugins, we recommend installing the latest official version from Google Play, we can uninstall the pre installed without problems. This models is a algo compatible with LibreELEC.

• Compatibility: HEVC with good performance at 10 bit color or HDR / VP9 correct in basic format, frameskip with P2.
• Tutorials: Install Addons in KODI in a simple way / LibreELEC installation guide for the TV-Boxes with Android

Video and audio results

• The maximum bitrate depends on the port used to connect or the limitations of SAMBA Networks.
• SW = does not have hardware acceleration and may have have some frameskip in very heavy files.

• 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.

• DRM: Google Widevine L1 / Microsoft Playready / HDCP 1.x (If we do not have them claim to the store by defective unit)

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.
