Redmi K80 Ultra Spotted on CMIIT

The highly anticipated Redmi K80 Ultra has surfaced in a new leak that could mark a huge leap in smartphone battery technology. According to a listing on China’s Ministry of Industry and Information Technology (CMIIT), the phone is tipped to feature a massive 7,270mAh battery—a significant upgrade over its predecessor, the Redmi K70 Ultra, which carried a 5,500mAh cell.

With Xiaomi yet to make an official announcement, this new detail gives us an exciting preview of what’s coming. Here’s a comprehensive breakdown of everything we know so far about the upcoming Redmi K80 Ultra, its expected specs, and why it’s creating a buzz in the Android flagship space.

Redmi K80 Ultra Battery Upgrade: What the CMIIT Listing Reveals

CMIIT Certification Confirms Large Battery

The Redmi K80 Ultra, spotted under model number 25060RK16C, was recently certified by the Chinese regulatory body CMIIT. The most eye-catching revelation? The phone will be equipped with a 7,270mAh battery.

Could Be Marketed as a 7,500mAh Battery

While the listing shows a 7,270mAh rating, OEMs, including Xiaomi, often round up for marketing purposes. So it wouldn’t be surprising if the Redmi K80 Ultra launches with a 7,500mAh battery tag, making it one of the largest batteries in any flagship smartphone to date.

Comparison with Redmi K70 Ultra

To put this into perspective:

• Redmi K70 Ultra Battery: 5,500mAh

• Redmi K80 Ultra (Rumored): 7,270mAh (~36% increase)

This huge leap indicates a focus on extended usage, better endurance for gaming, streaming, and multitasking—key priorities for today’s smartphone users.

Display & Design: Flat 1.5K OLED and Premium Build

High-Resolution Display with Flat Edges

Leaks suggest that the Redmi K80 Ultra will sport a flat 1.5K OLED display, which offers a resolution higher than standard Full HD+ panels, promising sharper visuals and vibrant colors.

The screen is also expected to have slim bezels on all sides, providing an immersive viewing experience ideal for gamers and binge-watchers alike.

3D Ultrasonic Fingerprint Sensor

In a notable upgrade, the device could feature a 3D ultrasonic fingerprint sensor, enhancing both speed and security. Unlike optical sensors, ultrasonic scanners work reliably even with wet or oily fingers.

Metal Frame with IP68 Certification

Another high-end touch is the rumored metal middle frame, which not only adds to the phone’s durability but also gives it a premium, flagship feel. Plus, the IP68 dust and water resistance rating means the phone can handle accidental splashes and short dips in water.

Performance: Dimensity 9400+ Chipset to Power the Beast

At the heart of the Redmi K80 Ultra is the rumored MediaTek Dimensity 9400 Plus chipset. MediaTek has been aggressively improving its high-end offerings, and the 9400+ is expected to compete closely with the Snapdragon 8 Gen 3 and 8 Gen 4.

Key performance expectations include:

• Improved AI processing

• Efficient multitasking

• Enhanced gaming with high frame rates

• Optimized power consumption

If this holds true, the K80 Ultra could become a top pick for performance-hungry users.

Camera: Still a Mystery

While no specific details have emerged regarding the camera setup, it is expected that Xiaomi may retain a similar triple-camera array as seen in the K70 Ultra, potentially with:

• A high-megapixel main sensor

• Ultra-wide lens

• Telephoto or macro shooter

Stay tuned—more details on the camera system will likely surface as we get closer to launch.

Expected Launch Timeline

Based on past release patterns, especially that of the Redmi K70 Ultra (launched in July 2024), the Redmi K80 Ultra could launch around July 2025 in China.

A global release may follow shortly afterward, possibly in August or September 2025, depending on Xiaomi’s strategy.
