Oppo is already hard at working bringing the next Reno series of 2025. The Reno 15 lineup is expected to break cover in the later part of the year. Now, ahead of that, a new leak has shed some light into the smartphones' core details.
Tipster Digital Chat Station (DCS) has shared the alleged specifications of the Reno 15, Reno 15 Pro and the Reno 15 Pro+ via Weibo. To recall, this is the same leaker who claimed that Oppo is going to bring three new devices with the Reno 15 series this time around.

DCS claims that the standard Reno 15 will feature a 6.59-inch LTPS flat OLED display with 120 Hz refresh rate and 1.5K resolution. Meanwhile, the Reno 15 Pro (could also be called the Reno 15s) will reportedly bring a smaller 6.31-inch 1.5K 120 Hz LTPS OLED panel with a 2.5D glass curvature and metal frame. The top-of-the-line Reno 15 Pro+ (could also be known as the Reno 15 Pro) is alleged to equip a 6.78-inch 120 Hz LTPO OLED display.
With three new display sizes on offer, we believe that Oppo is likely looking to cash in on the compact phone popularity this year, while retaining the familiar screen size options. The demand for 6.3-inch compact smartphones has surged in 2025, with smartphones like the Vivo X200 FE, the OnePlus 13s and more.

As for the other details, DCS claims that the with the Reno 15 lineup, Oppo will apparently equip each of the model with a 50 MP Samsung JN5 periscope camera unit. If true, the lineup will become the first Reno series to have achieved this feat. Moreover, two of the models (probably 15 Pro and the 15 Pro+) amongst the lot is apparently going to feature a 200 MP main sensor.
However, the standard Reno 15 will stick to a 50 MP main camera unit. All three smartphones are also said to feature a 50 MP selfie camera with support for 4K @ 60 FPS video recording capability. The lineup could also feature LUMO colour tuning.

Design-wise, the post has mentioned "cold carving process" for the back panel. Apart from this, no other detail has been revealed by DCS at the time of writing.
Previous rumours have indicated the MediaTek Dimensity 8400 series processors for the smartphones. The battery capacity on the devices could range somewhere in between the 6,500mAh range to the 7,500mAh mark. They could also feature 80W fast USB-C charging and 50W wireless charging support (except for the standard variant).
That said, since these are all rumours, take them with a pinch of salt. Oppo is yet to start teasing the smartphones. However, multiple reports indicate a November 2025 launch window for the devices in China with an estimated January 2026 launch in India.
