Xiaomi Mi Box 3 Enhanced Unboxing and Teardown

Xiaomi Mi Box 3 Enhanced launched earlier this year, must be one of the most powerful Android TV Box thanks to its Mediatek MT8693 hexa-core processor with two ARM Cortex-A72 cores @ 2.0GHz and four Cortex-A53 cores @ 1.6 GHz coupled with Imagination PowerVR GX6250 GPU. The downside is that the product has been specifically launched for the Chinese market, however we can still purchase it via Chinese e-retailers, and likely modify the user interface to use English. To find out, GearBest sent me one review sample. But first, I’ll check the device and hardware, before fully reviewing the TV box in a few weeks.

I normally received samples by DHL, but this time the postman brought it to me. It’s slower, but it can also be advantageous since custom duties are less likely.

The package has not much to it, but the back makes it clear it’s made for China as the specs are all listed in Chinese.

The white TV box comes with a Bluetooth remote control with two AAA batteries and a strap, a 12V/1.2A power supply, an HDMI cable,  and a user’s guide in Chinese only.

The device is rather small, with ventilation on the side, and only four port on the rear panel with two USB 2.0 ports, an HDMI 2.0 output port, and the DC jack. Xiaomi does not seem to think wired network matters much now, so they have not included an Ethernet port.

The device is quite hard to open as the two parts are tightly fitted together. I had to use two metal tools, one above one of the USB port to create an opening on the bottom, and another to pop the bottom cover out using that opening.

Processor based on ARM Cortex A72 do get hot, and as per the marketing materials released by Xiaomi the device includes a large heatsink and a fan.

I could remove the fan after loosening two screws…

and finally take out the heatsink after removing a bunch of smaller screws. The thermal design seems to be pretty good with two thermal pads connected to the heatsink. and covering the two main ICs: Mediatek MT8693 AAOV hexa-core SoC, and Mediatek MT7662 TUN handling WiFi 802.11 n/g/n/ac and Bluetooth 4.0 connectivity.

The unpopulated 4-pin header at the bottom of the picture above could be for the serial console. (Sadly not: see comment below).

[Update: I got a few more pictures thanks to Andreas

So we’ve got another Mediatek chip with MT6391A PMIC, Samsung  KLM8G1GEND-B031 eMMC 5.0 flash (8GB) and two RAM chips]

I’d like to thank GearBest for sending the latest version of Xiaomi Mi Box 3 TV box for review, and you could consider purchasing the device on their website for $85.05 shipped. Alternative shopping options include GeekBuying under the name Xiaomi Mi Box 3 Pro, and Aliexpress.
