After launching the Reno 14 series smartphones a short while back, it looks like Oppo is already hard at work prepping the Reno 15 series devices. Based on a new leak, looks like the upcoming Reno 15 lineup will comprise three smartphones.
Tipster Digital Chat Station (DCS) has revealed via Weibo that Oppo is currently testing three different screen sizes for the Reno 15 series – 6.3-inch, 6.59-inch and 6.78-inch. This indicates three new smartphones making its way to the Reno 15 family.

If true, this will be a first for the Reno lineup. Since the day of its inception, Oppo has consistently limited the Reno series to a standard and pro model. Now, with Reno 15, this trend is about to end.
DCS claims that initially, there was supposed to be a 6.3-inch device and a 6.78-inch smartphone. However, the 6.59-inch option was added later. This makes sense since the last two Reno series, Oppo Reno 13 and Oppo Reno 14, featured the standard model with a 6.59-inch display and the pro one with a 6.78-inch screen.
The interesting aspect is the addition of the 6.3-inch panel, which clearly indicates Oppo's interest in bringing a compact smartphone offering to the Reno lineup. The demand for 6.3-inch compact smartphones has surged in 2025, with smartphones like the Vivo X200 FE, the OnePlus 13s and more.

Hence, it will be interesting to see how Oppo positions this new smartphone within the Reno 15 lineup. It could either become the base Reno 15 offering or could sit in between the standard model and the Pro as the Reno 15 Mini.
As for the specifications of the lineup, DCS claims that all the new Reno 15 devices will launch with a flat display panel. Apart from this, no other key detail has been revealed. The Reno 15 Pro has earlier surfaced online with a 6.78-inch display and the MediaTek Dimensity 8450 processor at the helm.

It is also expected to become the first Reno smartphone to feature a 200 MP Samsung HP5 main camera sensor. The primary lens could get complimented with an ultra-wide angle lens and a 50 MP periscope camera.
As for the 6.3-inch variant of the series, not much is known apart from the fact that it is expected to feature a metal mid-frame and a periscope camera lens.
With that said, since these are all rumours at the time of writing, take them with a pinch of salt. We will be sure to report on something concrete as more information emerges here at Beebom Gadgets.
