XiaomiTime has spotted the REDMI K90 Ultra in the GSMA database, indicating that Xiaomi has already begun the official global registration process for its next-generation Ultra performance smartphone. Given past occurrences with the Xiaomi T series, such early detections hint towards an earlier-than-usual launch timeline.
GSMA Listing Suggests an Earlier Launch Window
The model number 2604FRK1EC in the GSMA database entry proves that the REDMI K90 Ultra has already entered formal certification stages. Traditionally, Ultra models starting with “06” identifiers are registered around June and their announcement occurs closer to August. However, fresh Xiaomi strategies possibly hint at a shift, much like how the Xiaomi 17T series is reportedly going to shift its launch schedules forward.
This change strongly suggests that the REDMI K90 Ultra may be officially released as early as April or May, marking a notable adjustment in Xiaomi’s flagship release planning. Such timing will enable Xiaomi to position the device more competitively in the first half of the year.
Dimensity 9500+ Expected as the Core Platform
As per the information received on the ground from supply chain sources, the REDMI K90 Ultra is supposedly fitted with the upcoming Dimensity 9500+ chipset by MediaTek. It would significantly focus on power efficiency, sustained performance in high workloads, and enhanced AI processing.
Such a move would confirm the recent strategy of Xiaomi to match Ultra models with the most advanced silicon MediaTek has to offer for flagship-level performance while maintaining thermal stability and battery efficiency.
Massive 10,000 mAh Battery in a Slim Body
Previous leaks have shown that the REDMI K90 Ultra could boast an unusually large 10,000 mAh battery, married to a body thickness of about 8.6 mm. If true, this combination would put the device in a class all its own, with extreme endurance without the bulk typically found with high-capacity batteries.
REDMI K90 Ultra tipped to come with a 10,000mAh battery in a sub-8.5mm body
Such a construction hints that Xiaomi is eyeing technologies of advanced battery density, making the REDMI K90 Ultra suitable for users who take long usage cycles of running, gaming, and extended outdoor activity without frequent charging.
China-Exclusive Launch With Global Path of Xiaomi T Series
Like its predecessors of the REDMI K Ultra series, the REDMI K90 Ultra is likely to be launched only in China. But these phones always come later in modified form for the worldwide market, carrying the branding of the Xiaomi T series, so this GSMA listing finds vital importance for international users who have been keeping tabs on upcoming Xiaomi T models.
