Redmi may be preparing a new flagship: the K90 Ultra. Following the recent launches of the K90 and K90 Pro Max, fresh leaks sketch a third model that appears to push battery life and display tech further — and may arrive next year.
What the leaks reveal
Early reports trace several key specs to the K90 Ultra, painting a picture of a phone focused on longevity and smooth visuals. While these details are unconfirmed, they come from sources tracking Redmi’s roadmap and component supply.
- 6.8-inch LTPS OLED panel with a "1.5K" resolution and a 165Hz refresh rate
- Very rounded corners and a metal frame
- Ultrasonic in-display fingerprint scanner
- Robust water-resistance rating (reportedly strong)
- Massive battery — most likely at least 8,000 mAh
- Processor rumored to be from MediaTek's Dimensity 9 series, possibly the Dimensity 9500+

How it stacks up against the K90 Pro Max
On paper the Ultra seems to push a couple of clear differentiators. Its 165Hz refresh rate would top the Pro Max, the chipset appears to change from whatever the Pro Max uses, and the battery capacity looks substantially larger. Those three items alone — higher refresh rate, a different SoC, and a beefier battery — suggest Redmi is aiming the Ultra at users who prioritize gaming smoothness and all-day endurance.
That said, many other details are missing: camera specs, exact charging speeds, screen brightness and color calibration, and pricing are all still unknown. Until Xiaomi or Redmi confirms official specifications, the comparisons remain provisional.
What to watch next
Expect more leaks and possibly certifications in the coming months that will clarify the SoC choice and battery/charging details. If the Dimensity 9500+ is confirmed, the K90 Ultra could offer a compelling alternative to Snapdragon-powered rivals — especially if the 8,000 mAh battery and 165Hz display are real. We’ll keep tracking the story and will update with hands-on impressions once the phone surfaces publicly.
