New information released by Microsoft to the FCC and possibly related to the Surface Duo 2 confirms that the device supports 5G technology, WiFi 6, wireless power transmission, NFC and UWB.
Microsoft is likely to unveil the Surface Duo 2 as the second generation of its dual-screen smartphone on September 21st. Now a new document in the FCC published It says that Microsoft Mobile supports two configurations: one will open the screen and the other will close the screen. In other words, the Microsoft phone will be like the previous generation clamshell.
Although most of the information in this document is incomprehensible, another part of it refers to a portable device. We also know that Microsoft has tested various modes for this device, including shell and flat. The Surface Duo 2 supports 4G and 5G and has passed hearing aid tests.
The firmware build number of this device is 2021.728.20, which is compatible with the format used by Surface Duo. In addition to supporting Wi-Fi 6, ultra-wideband (UWB), expansion and 5G multi-band, this product uses Wireless Power Transfer technology, which is the name for wireless charging.
When we hear the name wireless charging, we subconsciously remember Qi technology, but informed sources have not yet confirmed the existence of this technology on the Surface Duo 2. The previous generation of Microsoft mobile phones was so thin that it seemed almost impossible to put a wireless charging coil and temperature control in it.
If we do not consider the idea of supporting Qi wireless charging, the second scenario could be related to the charging capability of the Surface pen. However, there is little mention of pen support in the Surface Duo 2. For now, we only know that this phone uses a Snapdragon 888 chipset, 8 GB of RAM, a 5.8-inch display, three cameras and a 4400 mAh battery.
