The premium compact smartphone genre is now thought to have become so successful and influential that the supposed successor to the inaugural Vivo X200 Pro Mini might simply be introduced as the vanilla X300 instead.
It and its ~6.3-inch display might be 1 of no less than 4 allegedly upcoming devices snapped in a new photo freshly posted to Weibo by the eminent leaker Digital Chat Station.
It appears next to a virtually identically-sized handset, albeit with the distinctive red-accented lockscreen digital clock that is typically a hallmark of OnePlus' Android-based UI.
Therefore, it seems the "15T" might have just appeared in its first ever hands-on leak. It and its trio of putative rivals have a suspiciously similar front panel with slim bezels and a central punch-hole.
Each miniature display on show will integrate a 3D ultrasonic fingerprint sensor, according to Digital Chat Station, who also predicts wireless charging, periscope zoom lenses and deceptively large 6,000 to 7,000mAh batteries in all 4 devices.
The identities of the other 2 compact flagships remain a mystery for now, although the Oppo Find X9s and Honor "Magic8 Mini" are chief suspects here.
They are projected to be joined by at least 3 other contemporaries of similar size and premium specs in late 2025 and/or early 2026, such as the Xiaomi 16 and Samsung Galaxy S26.
That leaves scope for more newcomers from other brands, possibly even the vanilla iQoo 15 among them.
