OnePlus isn’t done with the 15 series yet. According to a new leak from reliable tipster Digital Chat Station, the company is already testing prototypes of the upcoming OnePlus 15T, which could arrive in the first half of 2026. And if these early details are accurate, the phone could ship with a Snapdragon 8 Elite Gen 5 chipset and a massive 7,000mAh battery, the biggest one ever seen on a OnePlus flagship.

OnePlus 15T Specifications (rumored)
The leak suggests that the OnePlus 15T will retain the same Snapdragon 8 Elite Gen 5 processor found in the OnePlus 15, Realme GT8 Pro and iQOO 15. That means users can expect the same top-tier AI features, gaming performance, and thermal efficiency from Qualcomm’s newest 3nm chip.
But the real headline feature might be its battery. The engineering prototype reportedly uses a 7,000mAh cell, a huge step up from the 6,260mAh unit found in the OnePlus 13T. That could make it one of the largest batteries ever in a mainstream flagship, potentially pushing battery life beyond two days of use.

OnePlus 15T Display, design, and other details
According to the same source, the OnePlus 15T will feature a 6.31-inch flat AMOLED display with 1.5K resolution and uniform bezels — keeping it compact but premium. The phone may also introduce an ultrasonic in-display fingerprint sensor, which is faster and more accurate than optical ones.
Camera details are still under wraps, but early reports hint that an ultra-wide lens could finally make a return — a feature notably absent from the OnePlus 13T.
Will OnePlus 15T come to India?
While the 15T’s global debut hasn’t been confirmed, OnePlus has a pattern: its “T” phones often arrive in India under a slightly different name. For instance, the OnePlus 13T was rebranded as the OnePlus 13s in the Indian market. If history repeats, the 15T might launch as the OnePlus 15s sometime after its Chinese release.
It’s also worth noting that the last T-series phone to officially launch in India was the OnePlus 10T, making this return to the lineup a potentially big deal for fans who prefer “refined flagship” editions.
