Redmi K90 Ultra Price in India: Launched With 8,550mAh Battery, 165Hz AMOLED
Redmi has introduced the K90 Ultra in China as a gaming-focused flagship that delivers strong performance while staying cool. It combines Qualcomm's top Snapdragon 8 Elite chip with a built-in cooling fan, a 6.83-inch 1.5K AMOLED display running at 165Hz, a large 8,550mAh battery with 100W charging, a dedicated D2 gaming chip, and up to 16GB of RAM. The phone starts at CNY 2,999 (about Rs. 35,500 by conversion) in China, but there is no word yet on a global or India release. As the follow-up to the K80 Ultra, it targets gamers who want high-end specs and steady performance at a lower price.
The Redmi K90 Ultra is built for high performance, with clear priorities. Its Snapdragon 8 Elite chip, built-in cooling fan, large battery, fast 100W charging, bright 165Hz display, and strong IP66, IP68, and IP69 durability ratings make it great for gaming and heavy use. The main compromises are its basic dual camera setup instead of a more versatile flagship camera system, and the fact that it's only available in China for now. It runs on Android 16-based HyperOS 3.
Below, we break down all the Redmi K90 Ultra's specs, including what the active cooling fan and Snapdragon 8 Elite offer, how the 8,550mAh battery performs, the strengths of its display and durability, and how it stacks up against the iQOO 13 and Realme GT 7 Pro, which also use the Snapdragon 8 Elite.

Redmi K90 Ultra Price and Availability
The Redmi K90 Ultra is available in China in four configurations: 12GB plus 256GB at CNY 2,999, 16GB plus 256GB at CNY 3,199, 12GB plus 512GB at CNY 3,499 and 16GB plus 512GB at CNY 3,699, roughly Rs. 35,500 to Rs. 43,700 by conversion. As a launch offer running through July 1, all versions get 200 yuan off, with the 16GB plus 256GB variant getting an extra discount, bringing effective prices down to CNY 2,799 to CNY 3,499. It comes in Space Silver, Shadow Black and Sky Blue. Redmi has not confirmed whether the K90 Ultra will launch globally or stay exclusive to China.
Note on availability: The Redmi K90 Ultra has only launched in China so far, and the rupee prices listed are just currency conversions, not official India prices. Redmi K-series phones are sometimes released globally under the POCO brand, so this model could show up internationally as a POCO device at a different price. With its Snapdragon 8 Elite and a starting price below CNY 3,000, it's a strong value for gamers, and any India or global version would likely be priced to compete with more expensive flagships.
Redmi K90 Ultra Performance: Snapdragon 8 Elite With an Active Cooling Fan
The Redmi K90 Ultra uses Qualcomm's top Snapdragon 8 Elite chip, made with TSMC's advanced 3nm process. It features an Adreno 840 GPU, can reach speeds up to 4.32GHz, and comes with up to 16GB of LPDDR5X RAM and up to 512GB of UFS 4.1 storage. There's also a dedicated D2 gaming chip that handles AI upscaling and frame interpolation, allowing for 1.5K gaming at up to 165fps in supported games. The real highlight is its built-in active cooling fan.
The active cooling fan is a standout feature because most phones only use passive vapor chambers, which can lead to performance drops as they heat up during long gaming sessions. The Redmi K90 Ultra includes an 18.1mm air-cooling fan and a 6,000mm² vapor chamber. Redmi says this setup can lower temperatures by about 10 degrees Celsius in 100 seconds, while staying quiet at 32dB. This means the Snapdragon 8 Elite can keep high frame rates for longer without slowing down, which is ideal for serious gamers. With the D2 chip's frame interpolation, the phone is designed for sustained high-refresh gaming, not just short bursts of peak performance. The active cooling sets it apart from other flagship phones.
Redmi K90 Ultra Battery: 8,550mAh With 100W Charging
The Redmi K90 Ultra carries a large 8,550mAh silicon-carbon battery, well above the 5,000mAh to 6,000mAh common in flagships, making it one of the biggest batteries in any high-performance phone. It supports 100W wired fast charging, 22.5W reverse wired charging and bypass charging, and ships with a 100W GaN charger in the box, backed by Xiaomi's Surge P3 charging chip and Surge G2 battery management chip.
What does the 8,550mAh battery mean in real use? The K90 Ultra stands out because it combines a huge battery with an efficient 3nm Snapdragon 8 Elite chip, which is rare in flagship phones. Redmi says the phone can last over two days with normal use, and even heavy gamers should get through a full day of intense gaming without needing to recharge midday. The 100W fast charging makes it quick to top up the big battery, and the included GaN charger means you don't need to buy one separately, unlike with many other brands. This battery and charging setup is a real advantage over most flagship phones.
Redmi K90 Ultra Display: 6.83-inch 1.5K AMOLED at 165Hz
The Redmi K90 Ultra has a 6.83-inch flat AMOLED display made with M10 material. It offers a 1.5K resolution (2772 x 1280), a 165Hz refresh rate, up to 3,500 nits peak brightness, a 480Hz touch sampling rate, and up to 3,500Hz instant touch sampling. It also supports HDR10+, HDR Vivid, Dolby Vision, and DC dimming. This display is excellent for gaming and watching media: the 165Hz refresh rate is higher than most flagships, the high touch sampling rate reduces input lag for competitive gaming, and the high brightness makes it easy to use outdoors. The flat screen is also better for gaming than curved displays. Overall, it's one of the best displays in its price range.
The Redmi K90 Ultra has a dual rear camera setup with a 50MP Light Hunter 800 main camera with a huge 1/1.55-inch sensor, f/1.68 aperture and OIS, and an 8MP ultra wide camera. It also comes with a 20MP front camera and support for 8K video recording. The main camera is decent, capturing good detail and dynamic range in most settings.
The camera system, however, is not as adaptable as the setups on camera-centric flagships, with no telephoto lens and a basic ultra-wide camera. Redmi has focused on performance, cooling, and battery life rather than camera versatility, which makes sense for gamers but may not be to the liking of photography lovers.
Design, Audio and Durability
The Redmi K90 Ultra has an aluminum alloy CNC frame, is 8.18mm thick, and weighs 227g, which is due to its large battery and cooling system. It has strong IP66, IP68, and IP69 ratings for dust and water resistance, and features a 3D ultrasonic fingerprint sensor. The phone also offers great audio with dual stereo speakers tuned by Bose, Dolby Atmos, and Hi-Res Audio certification. For connectivity, it supports 5G, Wi-Fi 7, Bluetooth 5.4, NFC, USB Type-C, an IR blaster, and a full range of satellite navigation systems including NavIC. It runs on Android 16-based HyperOS 3.

Here's how to compare these phones: All three use the Snapdragon 8 Elite chip, so the main differences are in other features. The Redmi K90 Ultra stands out with its much larger 8,550mAh battery, unique active cooling fan for longer gaming sessions, higher 165Hz refresh rate, and the fact that it includes a charger in the box. This makes it the best for battery life and cooling. However, it falls behind in cameras, as both the iQOO 13 and Realme GT 7 Pro have triple camera setups with telephoto zoom, and both charge faster at 120W. The iQOO 13 also has a sharper 2K display. When it comes to price and availability, the iQOO 13 and Realme GT 7 Pro are already available in India at Rs. 54,999 and Rs. 56,999, while the Redmi K90 Ultra is only in China for now, but its converted price is much lower. If it launches in India, likely as a POCO, it could be aggressively priced. Choose the K90 Ultra for battery life, cooling, and gaming, and the iQOO 13 or Realme GT 7 Pro for better cameras and confirmed India availability.

Final Thoughts
The Redmi K90 Ultra is an affordable gaming flagship and it delivers on its promises. It’s built for long-term, high-refresh gaming that most other flagships can't match, powered by the Snapdragon 8 Elite, a true active-cooling fan, and a specialized D2 chip. It’s a well-specced phone at a competitive price, with a massive 8,550mAh battery, 100W charging (with an included charger), a bright 165Hz display, Bose-tuned audio, and good IP66, IP68, and IP69 durability ratings.
The main drawbacks are the cameras and limited availability. The dual 50MP and 8MP cameras, while led by a strong main sensor, don't offer the telephoto options found on camera-focused competitors. At 227g, the phone is also quite heavy. Most importantly, it's only available in China for now, so buyers in other countries will have to wait and see if it launches elsewhere, possibly as a POCO model. For gamers and power users who care more about performance, battery life, and value than camera features, the Redmi K90 Ultra is one of the top gaming flagships for 2026. However, those who want better cameras or live outside China should consider other options.
Bottom line: The Redmi K90 Ultra launched in China, priced from CNY 2,999 (~Rs. 35,500) to CNY 3,699, with a launch discount until July 1. There's no India launch confirmed yet. It's a gaming flagship with a Snapdragon 8 Elite chip, built-in active cooling fan and vapor chamber, and a D2 gaming chip for 165fps gaming. It features a large 8,550mAh battery with 100W charging and an included charger, a 6.83-inch 1.5K AMOLED display at 165Hz and 3,500 nits, Bose-tuned stereo sound, and strong IP66, IP68, and IP69 ratings, running HyperOS 3. The cameras are capable but basic: a 50MP Light Hunter 800 with OIS, 8MP ultrawide, and 20MP front camera. Downsides include no telephoto lens, a heavy 227g weight, and China-only availability for now. Competitors like the iQOO 13 (Rs. 54,999) and Realme GT 7 Pro (Rs. 56,999) offer triple cameras and 120W charging, but have smaller batteries, no cooling fan, and are already available in India.
