Xiaomi's history is one of breaking all boundaries and Redmi K90 Max is no exception. The phone is expected to be released in April 2026 and is not only going to be a contender for flagship status, but it's going to question what a mid-range phone can be.
The K90 Max is powered by a massive 8,550mAh battery, a Dimensity 9500 chipset that uses 3nm technology and an actual cooling fan deep inside the body, making it more of a statement than an upgrade. Bold, loaded, and the price in Bangladesh is ৳62,000, why double for Samsung or Apple? So does it deliver? Let's find out.
An In-Depth Review on Xiaomi Redmi K90 Max
The Xiaomi Redmi K90 Max is a performance-oriented flagship smartphone aimed at gamers and power users who prioritize having the best performance possible, with the longest battery life, and an uncompromised user experience.
It also offers triple protection that ranges from IP66 to IP68 and IP69 is exceptionally rare at this price. This review highlights the pros and cons, its price in Bangladesh, gaming performance, display specs, and usability.
Box Content
This is what you get inside the Xiaomi Redmi K90 Max box:
- Xiaomi Redmi K90 Max Smartphone
- 100W Charger
- USB Type-C cable
- Silicone case
- User manual
- SIM tool

The opening of the box is satisfying right from the beginning. The Redmi K90 Max features a 100W fast charger, a silicone protective case (separate), a pre-applied screen protector, a SIM ejector tool, and the standard paperwork: quick start guide and warranty card.
One thing that stands out is the 100W charger which is still included with Xiaomi, whereas many high-end brands have dropped the charger from the box. The contents of the box are good all around.
Design & Build Quality
First impressions of Redmi K90 Max. It's 162.91 × 77.93mm and has a thin design of 8.18mm which gives it a sleek and confident look that is way better than most gaming phones. The design is clearly inspired by the Xiaomi 17 series, and it is equipped with a bold camera island and an offset lens layout, the cooling fan intake grille is not just a subtle addition, but is right there on the module. It's unique and yet not obnoxious.
The phone is available in three colours Silver, Blue, Black. The Shadow Black stone-textured back panel is a nice touch that is premium and will tolerate fingerprints. The aluminum frame is right-angled, providing a sturdy and structured grip when holding the device, while the frosted side buttons blend in with the body of the device.

The K90 Max is by no means a lightweight phone, weighing in at 227 grams. It's in your pocket and in extended one-handed sessions. But with an enormous 8,550mAh battery inside, it's not surprising that this phone is so heavy, and it's a good deal considering how long it lasts.
This phone really impresses in terms of high build quality. It is waterproof and water-resistant with water immersion rating of IP68 and IP69 (up to 1.5m of water for 30 minutes and high pressure water jet). Additionally, it is completely dustproof. This isn't typical even in phones that cost more, and it gives outdoor users and people in everyday circumstances a boost of confidence.
In summary, the Redmi K90 Max is a phone that seems designed to endure, be it physically or stylishly, it comes across as steady, functional, and an inexpensive but unassuming elegant device.
Display
The Redmi K90 Max's display is one of the best features of the device and it proves to be just as soon as you power it up. It is equipped with an AMOLED display panel of 6.83 inches resolution 1280×2772, which is sufficient to make the individual pixels completely imperceptible in normal use. The 90.3% screen-to-body ratio ensures that content gets the space it deserves, taking center stage.
It's smooth and buttery at 165Hz refresh rate from scrolling through social media to thrilling games. After using a 165Hz display for a day, it's easy to tell that it is slower than the 165Hz one.After one day a day of 165Hz display use, you can see the difference. The touch response is also instant and accurate, especially when playing competitively, and is coupled with a capacitive multi-touch panel.

This display really shines in brightness. The peak brightness is 3500 nits, making it extremely visible outdoors. The sun's glare is no longer an issue, even on sunny days, the screen is clear, readable and vibrant. This is a brightness level that is usually only used in ultra-premium flagships.
Support for HDR10+ greatly enhances the streaming experience. HDR-friendly content, such as Netflix, YouTube, and more, appears more dynamic and richly coloured, and truly film quality on this panel. Colors are vibrant and true, and contrast is nice, like with any AMOLED display.
The punch-hole cutout is employed so that the front is kept clean and has minimum design as well as Gorilla Glass protection that makes people feel more confident against scratches and minor drops. The phone is 19.5:9 and will play widescreen comfortably, as well as give the user the freedom to use one hand for typing.
In other words, it's a screen that is far more capable than a phone priced at twice the amount.
Camera
This Redmi K90 Max is a hands-on photography device. This is not a camera-centric telephone and Xiaomi would have you know. Rather than that, the camera system is meant to be useful in the real world, and not a hindrance on the performance and endurance of what this phone does best.
The back is equipped with a twin camera system. The main camera features a 50MP Light Hunter 800 sensor camera that has a wide f/1.68 aperture, optical image stabilization and a large 1/1.55-inch sensor size. The broad aperture is a significant bonus in this instance; it captures much more light than standard apertures, capturing brighter, more detailed shots in even the toughest of lighting situations.
The autofocus is quick and accurate and OIS ensures handheld camera stability. The secondary lens is an 8MP ultra-wide lens with an f/2.2 aperture, ideal for landscapes, architecture and group photos for a wider shot.
Daylight Photo:
In good lighting, the main camera performs impressively. Images are detailed, well exposed and natural in color. Highlights and shadows are captured well, even in most scenes, with dynamic range being dealt with with confidence. The resolution is 8150×6150 pixels, providing ample space for cropping without compromising detail.

Low-light Photo:
The combination of an f/1.68 aperture with OIS provides good performance in low-light scenarios. In low light, the images remain fairly low in noise and have good detail. The advantages of a dedicated camera flagship won't come close in the darkest of conditions, but results are good, nonetheless, for a phone at this price point.
The only downside is lack of a telephoto lens. No optical zoom, just digital zoom, reducing the versatility for faraway objects or compressing portraits. If you frequently take zoom photos, this will be a frustration that you should keep in mind when you're looking for a camera.

The K90 Max, on the video end, is really awesome. It shoots up to 8K at 30fps, 4K at both 30fps and 60fps, and 1080p at up to 60fps. Thanks to its gyro-EIS stabilization feature, it provides a good solution for creators and everyday videographers to keep video in check when moving.
The front camera is a 20MP wide-angle shooter which can record video at 1080p at both 30fps and 60fps. Selfies are high-definition with natural skin tones and video calls are clean and sharp. It's a good, no-frills selfie camera.
In sum, the camera system is adequate, functional, and interesting for regular photography, but don't purchase this phone for its cameras.
Performance & Software
The Redmi K90 Max is all about business. At its heart is the MediaTek Dimensity 9500, which leverages a state-of-the-art 3nm manufacturing process, similar to that employed by the most advanced chips in the world. This cleverly partitioned octa-core CPU configuration features one C1-Ultra core clocked at 4.21 GHz for the heaviest workloads, three C1-Premium cores clocked at 3.5 GHz for demanding tasks and four C1-Pro efficiency cores clocked at 2.7 GHz for everyday use and to keep power consumption low. It's a well-balanced architecture that provides power where and when it's required.
The Mali-G1 Ultra MC12 graphics card can handle a lot of graphically demanding games at high settings, and it will do so with no problem. Combined with the all-new D2 AI discrete graphics chip, the K90 Max features AI-enabled frame interpolation and super resolution, essentially taking PC-level visual improvements to mobile gaming. This setup has outperformed all other Dimensity 9500 devices in the benchmark test, including the Oppo Find X9 Pro.

Everyday usage runs smoothly. App launches are immediate, multitasking between demanding apps comes effortlessly and there's no lag or stutter whatsoever. The 64-bit provides seamless compatibility with the latest applications and future software.
For the software, it is powered by Android 16 along with HyperOS 3.0, which is the most polished UI that Xiaomi has ever used. HyperOS is definitely lighter, quicker and cleaner than the older versions of MIUI. Animations, transitions look smooth and app management is responsive. Minor system app ads are present, but can be turned off in settings with ease.
Overall, the performance experience of the Redmi K90 Max is a flagship in all aspects swift, steady and long lasting.
Battery & Charger
One of the best things about the Redmi K90 Max is its battery life and I mean, it's really, really great. It's powered by a 8,550mAh Lithium Polymer battery, which is one of the largest batteries ever included in a mainstream smartphone. With real-world use, two days between charges is a realistic expectation for most users. The phone keeps on running even after the other players have turned it off after a lot of gameplay.
The 100W wired fast charging support is provided by a 100W charging power supply included in the box and PD3.0 support is provided. That allows you to completely fill the battery in less than an hour, which is a pretty quick charge for such a big battery. No more charging overnight or during the day being a regular occurrence.

The 22.5W reverse wired charging is a nice touch as it lets you charge earbuds, smart watches, and even a friend's phone from the K90 Max. As you'd expect, the battery is non removable and is charged and data transferred by USB Type-C.
The Redmi K90 Max offers a real solution for users who have ever found themselves with a battery indicator that's on the verge of death.
Xiaomi Redmi K90 Max price in Bangladesh
The Xiaomi Redmi K90 Max is on sale in Bangladesh for BDT 62,000 for its 12GB RAM and 256GB configuration. This is an unofficial price as the phone is sold in the grey market without guarantees by the brand and service support.

Final Word
The Redmi K90 Max is an impressive phone that packs flagship-level performance in a package that few could fault. The battery life is excellent, the screen is gorgeous and the cooling system is unparalleled in this class. The only real compromises are the lack of a tele photo lens and unofficial availability in Bangladesh. For those who are willing to make those compromises, this phone is a great deal.
