FCC docs confirm the Galaxy Z Fold3 will support an S Pen and UWB, Z Flip3 also certified
Both the Samsung Galaxy Z Fold3 and Z Flip3 are FCC certified, which is one of the final steps before a device is launched on the market. This happens just days before Samsung’s virtual MWC event, though we’ll probably not get much more than one teaser before August. However, the FCC documents confirm some rumors about the collapsible devices.
Galaxy Z Fold3 (SM-F926U) supports an S-pen, although the device does not have a built-in slot for the pen. The FCC is talking about magnetic induction (which is used for wireless charging), so it is possible that the fold will at least be able to charge the stylus similar to how the Galaxy Tab S7 tablet does it, for example.
Fold definitely supports wireless charging at 9W (tested with EP-N5100 charging stand). On the wired route, a 25W charger (EP-TA800) is supported. The device has a 4,275 mAh battery built from two different cells (2,060 + 2,215 mAh).
The phone supports 5G, including mmWave on the n260 and n261 bands. It also supports Ultra Wide Band (UWB), the new wireless data transfer standard that competes with Bluetooth and is used in SmartTag +, for example (the non-plus version uses Bluetooth LE).
As for the Galaxy Z Flip3 (SM-F711U), no S-pens are mentioned for it, not even UWB, for that matter. However, it will have 5G mmWave connection on the same n260 and n261 bands. It also supports 9W wireless charging, though the wired option seems to go up to just 15W. Flips battery has 3,273 mAh capacity.
In terms of software, foldable devices with One UI 3.1.1 come according to Isunivers, which adds that One UI 3.5 does not exist. Instead, Samsung is jumping straight to version 4.0, which will first be tested on the Galaxy S series from next month.
