According to an FCC listing, the Galaxy Z Fold 3 will support the all-new S Pen Pro. Well, a previous FCC listing of the phone itself confirmed the support, but, now the S Pen Pro has gained FCC certification too and the listing reveals the name of the devices that will support it. Among many other Samsung phones, the name of the Galaxy Z Fold 3 is also written.
The listing reveals a few other details as well, including a 100mAh battery which is rated at 5.0V. It will charge over USB-C. The stylus might get recharged using the Galaxy Z Fold 3 reverse charging process.

Samsung's third-generation foldable smartphone, presumably called Galaxy Z Fold 3, is rumored to arrive in June. It is expected to have a number of improvements but the most important one is support for the S Pen stylus. A new report from NaverNews, a South Korean publication, corroborates these claims but has also mentioned a detail that is likely to disappoint many fans.
The report reveals that Galaxy Z Fold 3 will have S Pen support but will not have a dedicated slot like the Galaxy Note series devices. It means all buyers will have to carry the stylus around on their own. But as for why Samsung is not offering a dedicated stylus slot, there are reported to be two reasons behind the decision.
The first reason is related to space constraints. Samsung is reportedly working on making Galaxy Z Fold 3 slimmer and lighter than the predecessor. It means the team has to place all important internal components within a limited space. This is the reason it cannot afford to offer a stylus slot and compromise on space for other crucial components.
Another important reason is the durability of the foldable smartphone. Since these devices are already known to be more fragile than traditional smartphones, adding a stylus slot is likely to make them more vulnerable. It is important to note that this could also mean Samsung is planning to sell the S Pen stylus as an additional and optional accessory. This is exactly what it did with the Galaxy S21 Ultra launch.
