OnePlus Ace Turbo 6 Rumored With 6.78-Inch Flat Display and Snapdragon 8s Gen 4

A new leak from China hints that OnePlus is preparing a fresh “Turbo” model, and the early specs paint a pretty aggressive mid-range contender. According to tipster Digital Chat Station, an unnamed manufacturer is working on a phone powered by the Snapdragon 8s Gen 4, paired with a large 6.78-inch flat LTPS panel at 1.5K resolution. Most clues point directly to the OnePlus Ace Turbo 6.

The source claims the device has undergone “hardware-level improvements” to the 8s Gen 4 chip, though no specifics were shared. That’s fairly typical for pre-launch chatter. What stands out more is the display: a flat 6.78-inch screen with two refresh-rate options already being tested — 144 Hz and 165 Hz. For a mid-range price bracket, that’s unusually high. OnePlus has a habit of overdelivering on display fluidity in its Ace series, so the numbers fit the pattern.

There is also a claim of a “9K battery”. The phrasing is vague, but the intention seems to be clear: a 9,000 mAh-class battery or something close to it. If OnePlus really goes for a near-9,000 mAh cell, that would shake up the segment. Big batteries are trending again in China, and brands seem eager to push past the old 5,000 mAh ceiling.

Comment sections under the leak keep circling back to the same guess: this is the next Ace Turbo. Another Chinese source tied the leak to a new wave of mid-range Turbo devices from both Redmi and OnePlus, each positioned around 2000 yuan. Redmi is expected to use a new Dimensity chip, while OnePlus sticks with Qualcomm’s 8s Gen 4. Both are said to feature 1.5K displays, metal frames, and big batteries. The “Turbo vs Turbo” rivalry seems set for another round, and honestly, competition in this band has been good for pricing the past two years.

DCS hinted that the phone — along with its Redmi counterpart — should land before the Spring Festival. Certification progress apparently matches that timeline. OnePlus usually pushes the Ace lineup toward the first quarter anyway, so this feels like a natural window.

If these specs hold, the Ace Turbo 6 might be one of the more balanced mid-range releases early next year: high refresh rate, flat panel, strong chip, and a battery that sounds almost excessive but very welcome.
