Redmi K90 Ultra Tipped to Pack 165Hz Display and 8000mAh Battery

Redmi K90 Ultra Specs Leak

A new set of specifications for the Redmi K90 Ultra has appeared in online chatter, following the October 2025 China launch of the Redmi K90 and Redmi K90 Pro Max. A post on Weibo from the tipster Digital Chat Station has been circulating with details that some users in comments say pertain to a rumored Redmi K90 Ultra. The leak points to a high end gaming oriented handset with a large battery and a fast screen. The information aligns with earlier talk that the K90 Ultra could sit at the top of the Redmi K90 series, a line Xiaomi introduced as a flagship level in China. Officials or people familiar with the matter have not publicly confirmed the specifics, but the leak adds to the growing expectation around a potential new model in the lineup. The context remains that the K90 Pro Max is currently the flagship model in the lineup, having launched in China in October 2025 at a price around CNY 3,999 for the base configuration, and with a 6.9 inch OLED display that can reach high brightness. The current positioning of the Ultra is described as a step beyond the Pro Max in some early chatter, though no official confirmation has been issued yet. The timing mentioned puts an unveiling in China later this year as a possibility, though the timeline was not stated by any company representative in the material available online.

The core claim is that the Redmi K90 Ultra will pack a battery larger than 8000 mAh, a figure that would place it among the larger capacity flagships in this segment. In addition to the battery size, the leak mentions a 1.5K LTPS display and a high refresh rate rated at up to 165 Hz. The combination is described as a key feature set for the Ultra, suggesting a focus on gaming performance and smooth scrolling across the user interface. The Weibo post also ties the Ultra to a flagship tier chipset, with a MediaTek Dimensity 9500 octa core processor cited as the power plant. This chip is said to be built on a 3 nm process, a factor that could influence efficiency and sustained performance under load. A notable inclusion in the leak is an active cooling fan, described as potentially helping in temperatures during gaming or other heavy tasks.

Beyond the core engine and battery, the leak enumerates several design and hardware features. Reportedly, the phone will include a dual speaker unit and an ultrasonic fingerprint scanner for security. An IP68 rating for dust and water resistance is also claimed, which would align with Redmi's push toward rugged, premium build quality in the high end segment. Display size is described as roughly between 6.81 and 6.89 inches, adding to the large screen footprint that many gaming devices emphasize. In addition to the Ultra, references to the Redmi K90 Pro Max show a lineage of high end devices in the same family, with the Pro Max maintaining a position as the current flagship as of the last known launch window.

A number of caveats apply. The information comes from a post on a social platform commonly used for leaks, and the details have not been officially confirmed by Xiaomi or Redmi. The overall thrust of the material is consistent with prior reports that a Redmi K90 Ultra could enter the market later in the year, but exact specifications and availability hinged on company announcements.
