Xiaomi has unveiled the Redmi K90 Ultra in China, the successor to last year’s Redmi K80 Ultra. The design looks familiar, but Redmi has reworked the display, switched chipsets, and pushed the battery capacity higher, all while keeping the camera setup from taking a back seat. Anyone tracking Redmi K90 Ultra Nepal news will want to pay attention, since this phone could turn out to be one of the more balanced gaming flagships to arrive this year.
- Snapdragon 8 Elite, 16GB RAM
- 6.83-inch AMOLED, 165Hz, 3500 nits
- 50MP rear, 20MP front camera
- 8,550mAh battery, 100W charging
Display and Design
Redmi hasn’t reinvented the look here. The back panel now carries a horizontally aligned rectangular camera bump instead of the round module found on the K80 Ultra, and the phone tips the scales at 227 grams while staying at 8.2mm thick. Buyers get three color choices: Shadow Black, Space Silver, and Sky Blue. Durability hasn’t been left as an afterthought either, with IP66, IP68, and IP69 ratings plus Corning Gorilla Glass 7i on the front, a combination you don’t usually find on phones built primarily for gaming.
The screen itself is where things get interesting. It’s a 6.83-inch flat AMOLED panel with 1.5K resolution and a refresh rate that scales up to 165Hz, so fast animations and gameplay should feel notably fluid. Xiaomi has also packed in 12-bit color depth, Dolby Vision, HDR10+, and HDR Vivid support, and the panel can reportedly hit 3,500 nits at its brightest, which should help visibility hold up even in harsh outdoor light.
Performance
At the core of the K90 Ultra sits Qualcomm’s Snapdragon 8 Elite, fabricated on TSMC’s second-generation 3nm node, replacing the Dimensity 9400+ that powered last year’s model. Xiaomi has paired it with a dedicated D2 AI Gaming Graphics chip, designed to assist with frame interpolation and upscaling in games that support it. Storage and memory scale up to 16GB of LPDDR5X RAM and 512GB of UFS 4.1 space, and the software layer is HyperOS 3 running on Android 16.
During Xiaomi’s internal benchmarks, the phone reportedly stayed close to 60 FPS in graphically demanding 3D titles and held steady frame rates for hours, even with the surrounding temperature sitting around 30°C. That kind of sustained performance is largely down to how the phone manages heat, which brings us to its standout feature.
Built-in Cooling Fan
What really separates this phone from the rest of the pack is its cooling setup. A physical fan works together with a 6,000mm² vapor chamber to pull heat away during extended play sessions, and users can pick between Quiet, Smart, and Powerful modes depending on whether they’d rather prioritize cooling or keep the fan noise down.
Camera
The rear setup pairs a 50MP primary sensor, with an f/1.68 aperture and OIS, alongside an 8MP ultrawide camera. Xiaomi claims the phone can shoot 8K footage at 30fps and 4K at 60fps, numbers that hold up well for a device that’s marketed first and foremost as a gaming phone rather than a camera-centric flagship.
Selfies and video calls go through a 20MP front camera. While photography clearly isn’t the headline feature here, the hardware on offer should be more than capable enough for daily use without feeling like an afterthought bolted onto a gaming device.

Battery and Connectivity
Backing everything is an 8,550mAh battery, and Xiaomi is bundling a 100W charger in the retail box rather than selling it separately, so users can top up quickly without extra spending. There’s also 22.5W reverse wired charging built in for powering accessories. Sound comes through a symmetrical dual-speaker layout with Dolby Atmos support, which should make a noticeable difference for anyone watching content or gaming with the volume up.
Connectivity-wise, the phone covers 5G, Wi-Fi 7, Bluetooth 5.4, and GPS, and unlocking is handled through an in-display ultrasonic fingerprint sensor. The usual sensor lineup is present too, including a proximity sensor, compass, accelerometer, and gyroscope, which covers the basics most users rely on day to day.

Pricing in China starts at CNY 2,999 for the 12GB+256GB model and goes up to CNY 3,699 for the 16GB+512GB variant. There’s no confirmed Nepal launch yet, but the Redmi K90 Ultra Nepal price could realistically start around NPR 98,999, with the top variant reaching NPR 121,999.

What’s in the Box
Xiaomi has confirmed the Redmi K90 Ultra ships with a 100W GaN charger inside the retail box, a notable move given how many brands have started leaving fast chargers out entirely. Alongside the charger, buyers can expect the standard essentials that come with most Redmi launches, including a USB Type-C cable, a SIM ejector tool, basic documentation, and a protective case, though Xiaomi hasn’t officially itemized the full box contents at the time of writing.
Conclusion
Between the Snapdragon 8 Elite chipset, the 165Hz AMOLED panel, and a cooling fan that actually does meaningful work, the Redmi K90 Ultra has the ingredients to compete seriously in the gaming phone segment. What makes it more interesting is that Redmi hasn’t treated the cameras as an afterthought, something a lot of gaming-first phones tend to get wrong. There’s no official word yet on whether it’ll launch officially, but if it does make its way here, Redmi K90 Ultra Nepal shoppers hunting for a performance-focused flagship will have a genuinely strong option to consider.
