Redmi K90 Ultra: Specifications
As per the current leaks, the Redmi K90 Ultra could be powered by an octa-core MediaTek Dimensity 9500 chipset. It is worth noting that Redmi usually adopts MediaTek chipsets in its Plus models. And this makes the pairing of a flagship MediaTek processor with the Ultra branding particularly interesting.
The other key highlight is the inclusion of an internal cooling fan, which would be a first for any Xiaomi smartphone. This is a clear indication that Redmi is targeting active gamers and power users by reducing thermal throttling during long sessions.
Battery life is shaping up to be another key selling point. Leaks currently point to an 8,500 mAh battery, with some reports suggesting that Redmi may even be testing larger battery capacities. Regardless, this Redmi K-series smartphone is expected to support 100 W wired fast charging.
The K90 Ultra is tipped to feature a flat LTPS OLED panel measuring roughly 6.81 to 6.89 inches, naturally with a high refresh rate that could go up to 165 Hz. At the same time, the screen may also include an ultrasonic in-display fingerprint sensor. Lastly, the phone is expected to sport a premium metal frame.
For now, all of this remains speculative, as there is no official confirmation from the brand. That said, the leaks suggest that the Ultra model could lean more towards being a gaming-focused flagship, while still retaining a premium, all-round flagship appeal.
For context, the recently launched Redmi K90 Pro Max comes with a large 6.9-inch OLED display with up to a 120 Hz refresh rate and is powered by Qualcomm’s flagship Snapdragon 8 Elite Gen 5 chipset. Naturally, expectations are that the K90 Ultra will push things a step further, with even more premium features aimed at power users.
