REDMI K90 Ultra: Full Specs, Leaks, Launch Date, Battery & Gaming Features

Introduction

The REDMI K90 Ultra could become one of the most powerful Redmi phones ever launched. Based on recent leaks and certification reports, the device may bring a huge battery, top-tier chipset, fast charging, and even active cooling.

That combination makes it especially exciting for:

• mobile gamers
• power users
• heavy multitaskers
• users who want flagship performance without paying ultra-premium prices

If the leaks are accurate, the K90 Ultra could become one of the most talked-about Redmi phones of the year.

Design and Display

The REDMI K90 Ultra is expected to arrive with a premium flagship design, possibly featuring a solid metal frame and a performance-focused body style.

Expected Display Features

• Display: 6.8-inch OLED panel
• Resolution: 1.5K
• Refresh Rate: 165Hz
• Design: Slim-bezel flat/near-flat gaming-focused display
• Build: Premium metal frame expected

The phone is expected to offer a smooth, sharp, and highly responsive display experience, making it ideal for gaming, scrolling, and media consumption.

A high refresh rate panel like this would also help the phone feel more premium in daily use, especially when combined with flagship-level hardware.

Performance and Processor

Performance is expected to be one of the biggest strengths of the REDMI K90 Ultra.

Performance Highlights

• Processor: MediaTek Dimensity 9500 expected
• RAM: 12GB / 16GB expected
• Storage: 256GB / 512GB / 1TB expected
• Gaming: High-end gaming and multitasking performance

This setup should make the device extremely capable for:

• competitive gaming
• heavy multitasking
• long gaming sessions
• demanding apps and flagship-level daily use

If the leaks are accurate, the REDMI K90 Ultra could easily become one of the strongest performance phones in its class.

Why the Dimensity 9500 matters

The expected MediaTek Dimensity 9500 chipset could be one of the most powerful smartphone processors of its generation. That means users can expect:

• smoother gaming
• faster app launching
• stronger thermal performance
• flagship-level speed for everyday tasks

For a performance-focused phone like this, the chipset will likely be one of its biggest selling points.

Cooling and Gaming Features

One of the most interesting rumors surrounding the REDMI K90 Ultra is its possible built-in active cooling system.

Expected Gaming Features

• Built-in cooling fan rumored
• Better thermal management
• Stable long-session gaming performance
• Reduced overheating under heavy load

If Redmi really adds active cooling, the K90 Ultra could move closer to the category of a true gaming phone, rather than just a normal flagship.

This would be especially useful for games like:

• PUBG Mobile
• COD Mobile
• Free Fire
• MLBB

That alone could make the REDMI K90 Ultra one of the most exciting Redmi gaming phones yet.

Why cooling matters

A powerful processor is great, but without proper cooling, long gaming sessions can cause:

• heat buildup
• performance drops
• frame rate instability

That’s why cooling could become one of the K90 Ultra’s biggest practical upgrades.

Camera Setup

While the REDMI K90 Ultra appears to focus mainly on performance, it is still expected to offer a strong flagship-level camera setup.

Expected Camera Features

• Main Camera: High-resolution primary sensor
• Ultra-wide Camera: Expected
• Telephoto / Additional Lens: Possible advanced secondary setup
• Photography Focus: Daily photography, gaming phone camera balance, AI imaging

Although the camera may not be the main selling point of this device, Redmi is still expected to deliver a solid all-round flagship camera experience.

This means users may still get:

• decent low-light photography
• sharp daylight images
• stable video recording
• useful ultra-wide performance

For most users, that would be more than enough for social media and daily use.

Battery and Charging

Battery life could become one of the biggest headline features of the REDMI K90 Ultra.

Expected Battery Specs

• Battery: Around 8,500mAh
• Charging: 100W wired fast charging
• Battery Focus: Extreme endurance and long gaming backup

If these leaks are accurate, the phone could offer:

• all-day heavy usage
• very long gaming sessions
• excellent standby battery life
• much better endurance than many current flagships

A battery this large would instantly make the K90 Ultra one of the most impressive battery-focused flagship phones of the year.

Why this battery is a big deal

Most flagship phones today still stay around the 5,000mAh range, so an 8,500mAh battery would be a huge jump.

That could make the REDMI K90 Ultra ideal for:

• gamers
• travelers
• students
• power users who hate charging often

And with 100W fast charging, Redmi could balance that large battery with practical fast top-ups.

Security and Extra Features

The REDMI K90 Ultra is also expected to include several premium extras.

Expected Extra Features

• Ultrasonic in-display fingerprint scanner
• Premium build quality
• Flagship gaming optimization
• Performance-focused tuning

These kinds of features help push the K90 Ultra beyond just raw specs and make it feel more like a complete flagship device.

An ultrasonic fingerprint scanner, if included, would likely provide:

• faster unlocking
• better accuracy
• a more premium flagship experience

That would be a nice touch for a device aimed at serious users.

Software

The phone is expected to launch with the latest Android version and Xiaomi’s latest software experience.

Software Features

• OS: Android 16 expected
• UI: HyperOS expected
• Features: Gaming tools, battery optimization, performance modes, smooth system animations

Xiaomi’s newer software is expected to continue improving in:

• gaming performance
• system smoothness
• battery management
• AI-powered features

For a performance-focused device like this, software optimization will be just as important as hardware.

HyperOS could also help improve:

• touch response
• gaming stability
• background app efficiency
• overall user experience
