Xiaomi Mi Box 4S Max, new Android TV-Box with 4 GB of RAM

Surprisingly Xiaomi has presented its new Android TV-Box called Xiaomi Mi Box 4S Max. A version that maintains the classic design of the brand, has SoC Amlogic S905X3 and integrates 4 GB of RAM.

This TV-Box surprises us with the incorporation of 4 GB of RAM and no less than 64 GB of storage, the normal for streaming is a 2/8GB configuration as in the current Mi Box S. On the other hand, it does not risk much with the processor, the Amlogic S905X3 is already a few years old, we have seen it in other models in the reviews that we made on our website.

This TV-Box for now is only available in China and as it is logical it does NOT have the certificates to watch Netflix, Prime Video, YouTube or other streaming services in the highest qualities, we will have to wait for the Global version to have a useful device in our country. We have, as usual, with a remote control with built-in microphone to give orders to the Chinese assistant of the MIUI for TV system that we have installed.

Xiaomi Mi Box 4S Max specifications

The new Xiaomi Mi Box 4S Max includes the AMlogic S905X3 SoC, a Quad Core manufactured in 12 nm. A chip with ARM Cortex-A55 processors that reach 1.5 GHz speed and also integrates a Mali-G31 MP2 GPU. You can see the power of this SoC in a comparative article of the S905X3.

In the video decoding section the VPU is an Amlogic Video Engine 10 with basic HDR support, this VPU does not have AV1 codec, something that limits the box quite a lot in terms of 8K content that it promotes so much in its advertising. It has 4 GB of RAM and 64 GB of eMMC storage. Surely we will be able to expand via its USB-OTG port, although it remains to be seen.

Other features

In the field of wireless connectivity we find integrated on board wifi aC Dual Band and Bluetooth. The connectors included in the plastic box are very few, a USB 3.0 Type-A port and a video output HDMI 2.1 4K@60fps HDR and supposedly also 8K, but for practical purposes without AV1 support is limited.

In this TV-Box we have as operating system MiUI for TV designed entirely for the Chinese market and supposedly run under Android 11. Included as standard is a Bluetooth remote control with microphone for Google Assistant with a fairly conventional design. It also has support for Dolby and DTS audio, it does not have Dolby Vision or Atmos support, certificates intended only for the Western streaming sector.

Price and availability

  • The Xiaomi Mi Box 4S Max will soon be available for purchase on Aliexpress for about $96 / 90€ (in China it is worth about $75 / 499¥), but we recommend waiting for the Global version because the Chinese version is almost useless in the West.
  • Perhaps this Box will remain exclusively in China and we will never see it in the West with the necessary certificates.
