Redmi K90 Ultra Leak: 8,500mAh Battery, Fan Cooling Revealed

Leak suggests the Redmi K90 Ultra will blend marathon battery life and active cooling: Dimensity 9500 chipset, internal fan, 8,500mAh battery with 100W charging, and a 6.8-inch 1.5K 165Hz display for sustained gaming.

Redmi K90 Ultra Leak: 8,500mAh Battery, Fan Cooling Revealed

3 Minutes

Imagine a smartphone with a tiny fan humming quietly under its metal frame. Sounds like a PC trick, right? Except recent leaks suggest that's exactly where Redmi might be headed with the K90 Ultra.

A tip from Digital Chat Station points to MediaTek's Dimensity 9500 powering the device. That fits Redmi's habit of leaning on the 9-series silicon for its Ultra models, but there’s a twist: the much-rumored 9500+ overclocked variant appears to be off the table this time. Simple change on paper. Big implications in practice.

What really turns heads is the report of an internal active cooling solution. If true, the K90 Ultra would be the first phone inside the Xiaomi stable to use a built-in fan designed to keep the chipset closer to peak performance during long gaming sessions. In other words: fewer thermal slowdowns, steadier frame rates, and a handset that treats marathon play like its job.

This could be Xiaomi group's first phone with active internal cooling and an 8,500mAh battery.

Speaking of stamina, leaks claim an enormous 8,500mAh cell sits inside the chassis, with engineers reportedly testing even higher capacities. Charging is expected to cap at around 100W wired, possibly via high‑power PPS standards, which suggests a careful balance between ultralong battery life and reasonably fast top-ups.

The screen is not being neglected. Sources point to a flat 6.8-inch panel at roughly 1.5K resolution and a refresh rate that could climb to 165Hz — a combo built for smoothness without the extreme power waste of even higher resolutions. Add an ultrasonic in-display fingerprint sensor, a metal frame, and full water resistance, and you get a phone that looks to be pitched at serious users rather than casual buyers.

Timing? Expect a reveal around May or June, according to the same leak, and Redmi may pair the phone announcement with the Redmi K Pad 2, a performance-focused tablet aimed at the same crowd hungry for power and endurance.

Redmi seems determined to blur the lines between handheld gaming rigs and mainstream flagship phones. The real question now: will the market want a phone that behaves like a compact console, or is this the start of a new performance-first mainstream trend?
