These initial speculations suggest a relationship to the 13 series. Preliminary OnePlus 15T rumors indicate that the device might feature the Snapdragon 8 Elite 2 SoC and have a larger battery than the anticipated flagship 15. Other leaked specifications state that the phone could come with a smaller 6.3-inch 1.5K display integrated with a 3D ultrasonic fingerprint sensor. The OnePlus 13T surpasses the flagship 13, offering a 6,260mAh battery compared to the base 6,000mAh capacity of the latter.
Speculations regarding OnePlus’ upcoming compact flagship alternative have emerged, implying it might excel in one particular area. Information about the OnePlus 15T (skipping the 14) surfaced on Weibo in a now-removed post by Digital Chat Station (via NotebookCheck). The tipster shared some alleged “exclusive information” regarding the compact flagship, which might include a crucial feature: Qualcomm’s forthcoming Snapdragon 8 Elite 2. This isn’t particularly unexpected, as the OnePlus 13T utilized the SD 8 Elite, similar to the original 13 flagship.
Furthermore, DCS reports that the OnePlus 15T is expected to have a larger battery than the anticipated OnePlus 15 flagship. Details on its presumed capacity remain unspecified for now.
Given that this is likely to be another compact offering, rumors suggest the 15T could feature a 6.3-inch 1.5K resolution display. Below it, a 3D ultrasonic fingerprint sensor may be positioned, all enclosed in a “metal frame.”
While OnePlus generally unveils its flagship devices (internationally) after the new year, DCS asserts that the OnePlus 15T could potentially launch in the “first half” of 2026.
The battery is a focal point of conversation, as rumors indicate that the OnePlus 15T flagship variant may boast a larger capacity than the original flagship. Although we anticipate OnePlus to maintain its robust Glacier battery technology, a similar situation occurred this year with the OnePlus 13 and 13T. The former debuted with a powerful 6,000mAh battery; however, the 13T increased that slightly to a 6,260mAh battery.
Considering the precocity of these rumors, it remains uncertain how much larger the OnePlus 15’s battery might be (if an upgrade is on the horizon). There’s speculation that the Chinese OEM could retain it at 6,000mAh with an enhancement prepared for the 15T, but that is yet to be confirmed.
As the 15T will likely build on the OnePlus 15, some recent leaks might provide insights into what to anticipate. One notable similarity is its alleged 1.5K resolution for the display. However, specifications could change, as the flagship may feature a 6.7-inch display with that resolution. Conflicting rumors exist regarding its primary camera. Some assert it will arrive at 50MP, while others indicate OnePlus might elevate it to 200MP.
In any case, OnePlus flagships typically debut in China first, around the year’s end, in the fall. This schedule may shift slightly earlier this year, following rumors that the Snapdragon 8 Elite 2 could be introduced in September, rather than October.
