OPPO Find X9s & OnePlus 15T: The Upcoming ‘Mini-Flagships’ Are Revealed
The year 2026 is shaping up to be busy for compact smartphone enthusiasts in China. Several brands are already working on smaller formats, countering the trend of giant screens that have become the norm. Among them, OPPO and OnePlus appear to be the most advanced, and a recent leak from the informant Smart Pikachu has provided early details about the Find X9s and OnePlus 15T.
According to him, both OPPO and OnePlus are preparing a compact variant with a 6.3-inch display, positioned as a regular update to their lineups.
While the final names are not yet confirmed, everything suggests that we are indeed talking about the Find X9s and the OnePlus 15T.

A Compact Format with Premium Positioning
The source mentions an upgrade in several aspects. Both models would feature an ultrasonic fingerprint sensor under the display, a feature previously reserved for the highest-end devices. The design would also evolve towards a mid-range metal chassis and a refreshed visual identity, particularly with rounder corners.
The most surprising point concerns the battery. OPPO and OnePlus are reportedly testing prototypes with capacities approaching 7,000 mAh, an impressive figure for a compact smartphone.
If confirmed, these models could become the most enduring “mini-phones” on the market.
OnePlus 15T: Is an Ultra-Wide Angle Making a Comeback?
When asked about the camera capabilities of the upcoming compact version of OnePlus, Smart Pikachu was quick to temper expectations: the OnePlus 15T will primarily be a “performance-oriented” smartphone.
However, several reports suggest that OnePlus is indeed planning to add an ultra-wide angle lens, which was missing from the current generation, addressing one of the significant criticisms leveled at the previous model.
High-End Chips and Release Date
On the processor front, the approach would remain the same as with the main versions. The OPPO Find X9s is expected to debut the Dimensity 9500+, while the OnePlus 15T will take advantage of the brand new Snapdragon 8 Elite Gen 5, a chip specifically designed for top-tier performance.
As for the release date, Smart Pikachu mentions a fairly clear window: March 2026, assuming the timeline remains unchanged.
A Return of High-End Compact Phones?
If these leaks prove true, OPPO and OnePlus could play a vital role in reviving a nearly extinct segment: that of genuinely manageable premium smartphones. A compact size, a powerful battery, a refined design, and the latest chips on the market… this formula has everything to appeal to those who no longer want to choose between practicality and ambitious specifications.
