OnePlus has started warming up the Ace 6 Ultra, a gaming phone that is leaning hard into the playbook: flashy rear styling, a 165Hz display, a bigger battery, and design tweaks meant to make long sessions less annoying. The phone is expected to launch later this month in China, where it will run straight at the Redmi K90 Max, due on April 21.
A back panel built to look fast
The black version shown so far uses a layered texture created with a 3D light engraving process, which gives the rear panel a shifting look as it catches the light. There is also a large ”Ace” mark across the back, plus a simplified rectangular camera module and a vertical branding strip. In other words, this is not trying to be subtle, which is probably the point.
OnePlus says the camera bump has been flattened so it is less likely to get in the way of your fingers, while the internal layout has been adjusted to handle heat better. That tracks with the rest of the pitch: if a phone is going to be sold as a gaming-first device, comfort and thermals matter as much as the shiny stuff on the outside.
OnePlus Ace 6 Ultra specs: 165Hz screen and big battery
Up front, the Ace 6 Ultra is expected to use a 165Hz display developed with BOE, a spec that puts it closer to gaming monitors than the 120Hz panels that still dominate mainstream phones. The company is also said to be tuning software to keep frame rates steady without draining the battery too quickly, which is the sort of promise every gaming phone makes right before the benchmarks show up.
- 6.78-inch OLED display
- 1.5K resolution
- 165Hz refresh rate
- Dimensity 9500 chipset
- 8,500mAh battery
- 100W charging
If those rumored specs hold, the battery could be the headliner here. An 8,500mAh cell is unusually large for a performance-focused phone, and OnePlus seems to be betting that endurance is the easiest way to make a gaming device feel genuinely different rather than just louder.
Rumored OnePlus Ace 6 Ultra specs and likely rivals
Recent reports also point to up to 16GB of RAM and 1TB of storage, plus a 50-megapixel main camera, an 8-megapixel secondary sensor, and a 16-megapixel selfie camera. The phone is expected to ship with Android 16 and ColorOS 16, and the listed color options are Titanium and Black.
The bigger question is less about the parts list and more about where OnePlus plans to take this model. China has become a battleground for performance phones from Redmi, iQOO, and realme, and that pressure tends to push brands toward bigger batteries, faster panels, and more aggressive cooling. The Ace 6 Ultra appears to be following that script closely.
For now, there is still no clear word on a global version. If OnePlus keeps the Ace line China-only, the Ultra will be another example of a brand testing its most extreme ideas at home first and leaving everyone else to stare at teaser images and do the math.
