What would you like to know

  • New FCC documents approved on September 17 filed by Microsoft are likely for Surface Duo 2.
  • The documents confirm 5G, NFC, UWB, Wi-Fi 6 and a “wireless power transfer.”
  • While it might be Qi wireless, it’s more likely an inductive load for a Surface Pen.

On September 22, Microsoft is expected to unveil Surface Duo 2, the tracking device for its unique dual-screen theory of handheld computing.

New FCC Documents released on September 17 reveals a few more details about the future device, although photos, diagrams and detailed descriptions are withheld until January 2022.

While most of the data, categorized under C3K1995 (C3K is Microsoft recipient code, 1995 is FCC product code), are lackluster test results, there are a few details that confirm that this is Surface Duo 2.

On the one hand, it is referred to as a “portable handset” in all documents. There are several references to various “postures” for testing the device, including “flip and flat”. The device has 4G and 5G capabilities. Tests have been carried out for the use of hearing aids – a requirement for “digital cordless phones”. Even the firmware version number – 2021.728.20 – matches the format used by Surface Duo.

In addition to confirming Wi-Fi 8021.11b / g / n / ax (aka Wi-Fi 6), multiband 5G, NFC and Ultra wide band (UWB, probably for accessories and fast file transfers like Nearby Share), there is also mention of “Wireless Power Transfer,” aka fancy FCC which talks about wireless charging.

While it’s easy to switch to Qi-wireless as a benchmark, our sources, so far, have yet to confirm native Qi wireless charging for Surface Duo 2. Indeed, the device is so thin that put the Qi coil in and attenuating the heat generated might be too difficult to implement.

An alternative theory to Qi wireless charging is that Surface Duo 2 can support inductive charging for a Surface Pen similar to how Apple iPads can charge Apple Pencil by magnetically sticking it to the device. Granted, support for Surface Pen and Surface Duo 2 is not yet widely reported in terms of actual capabilities like haptic feedback, storage, and support in Android, leaving it all a bit of a mystery.
