Known for releasing a flagship device followed by a sub-flagship Ace series model toward the end of each year, OnePlus shook things up last year with separate launches for the OnePlus 13 and the Ace 5 lineup. However, new leaks suggest the company is changing course in 2026.

OnePlus 15 and Ace 6 to be introduced together

Instead of staggered events, the upcoming OnePlus 15 and Ace 6 series are expected to debut simultaneously this October, according to insider Digital Chat Station.

The OnePlus 15 will feature a flat 6.78-inch OLED LTPO 2K display with ultra-thin bezels on all sides. Under the hood, it’s powered by the Snapdragon 8 Elite Gen 2 chipset, paired with a robust battery exceeding 7,000mAh capacity. Charging capabilities include 100W wired and wireless support. Other highlights include a metal frame, ultrasonic under-display fingerprint sensor, a side-mounted Plus button, a 0916-axis haptic motor, and an IP68/69 rating for dust and water resistance.

Meanwhile, the Ace 6 will sport a slightly larger 6.83-inch flat OLED screen with a 1.5K resolution and an impressive 165Hz refresh rate. Powered by a Snapdragon 8-series processor, it’s expected to come with around a 7,800mAh battery, an ultrasonic fingerprint reader beneath the screen, a metal mid-frame, and IP68 certification for protection against dust and water.
