Redmi is expected to launch its new flagship smartphone, the Redmi K90 Ultra, in April 2026. This projection stems from a leak by a tipster on Weibo, supported by the device’s registration details found in the GSMA IMEI database.
The listing of the model number 2604FRK1EC in the GSMA IMEI database since December 2025 suggests an early debut, with the “2604” code hinting at an April 2026 release. This would mark a quicker launch cycle compared to the previous generation.
Key Specifications and Features
The Redmi K90 Ultra is reportedly powered by the MediaTek Dimensity 9500 chipset. This SoC is known for delivering high performance while maintaining energy efficiency. MediaTek’s chip aims to offer a solid balance for heavy multitasking and demanding mobile games.
The smartphone will feature a 6.8-inch display with an outstanding refresh rate of up to 165 Hz. Such a high refresh rate ensures ultra-smooth animations and transitions, enhancing the user interface experience beyond the usual 60 Hz or 120 Hz panels found in many devices.
Battery capacity is another highlight, with an 8,500 mAh cell that supports 100W fast charging. This combination promises extended usage time and rapid recharging, addressing the needs of modern power users.
Additionally, Redmi plans to integrate an active cooling system, which includes a physical fan inside the chassis. This cooling method helps keep the chipset temperature stable during intense tasks like gaming, potentially improving performance and preventing overheating.
Audio and Multimedia Enhancements
Leaks suggest that the Redmi K90 Ultra could come with stereo speakers tuned by Bose. This collaboration would enhance the audio output, adding to the phone’s appeal for media consumption and gaming. The emphasis on sound quality complements the device’s impressive display and performance features.
Market Positioning and Previous Series Context
The Redmi K90 Ultra will join the Redmi K90 series, which already includes models launched in late 2025 such as the Redmi K90 and Redmi K90 Pro Max. Unlike the other models that used Qualcomm chips, the Ultra variant shifts to MediaTek, possibly to differentiate its capabilities and target a specific audience.
Although the current leaks give detailed insights into possible specs and launch timing, Xiaomi and Redmi have yet to officially confirm the release date or final specifications. The company traditionally announces official information a few weeks before the commercial launch.
Global Launch Prospects
While the Redmi K90 Ultra is initially targeting the Chinese market, there is a strong possibility of a global version arriving later. However, Xiaomi might use a different name for international markets as part of its rebranding strategy seen with prior Redmi devices.
