It is not immediately clear which of the two smartphones Oppo has teased. However, both of them are marketed with the "Durable Champion" tagline. Hence, expect "durability" to be a big USP of the smartphones.
Apart from this, there has been no official mention of the devices' specifications. Also, interestingly, the next "F" series smartphones bear the "31" moniker. There has not been an Oppo F30, making the Oppo F29 series a direct predecessor to the upcoming series. Also, there was no "Pro+" last time.

As for the key specifications, a previous leak hinted at a 7,000mAh battery across the Oppo F31 series. The same capacity will allegedly be common across all three smartphones. It could also feature 80W fast charging, just like the F29 series.
The devices are also said to feature a flat display just like the previous generation models. Under the hood, the standard Oppo F31 5G is expected to bear the MediaTek Dimensity 6300 processor. Meanwhile, the Oppo F31 Pro 5G is said to be powered by the MediaTek Dimensity 7300 chipset.
The Oppo F31 Pro+ 5G will most likely be the only model to bring a Qualcomm SoC to the table. The phone is said to be powered by the Snapdragon 7 Gen 3 chipset. It could also bring 12 GB RAM and 256 GB storage.
That said, since the official launch date confirmation is here, expect Oppo to slowly reveal the other details of the phones in the coming days.
