Redmi is preparing to unleash its most ambitious flagship yet — the Redmi K80 Ultra, and recent official teasers have revealed several key features that position this device as a serious contender in the high-performance smartphone category. With a focus on power, endurance, and heat management, the K80 Ultra is shaping up to be a beast in the mid-2025 market.
Power That Lasts: Giant Battery + Fast Charging
One of the most eye-catching features of the Redmi K80 Ultra is its enormous 7,270mAh battery, which the company may brand as a 7,500mAh unit. This upgrade promises significantly extended usage, with early estimates pointing toward up to two full days on a single charge. Despite its size, Redmi isn’t cutting back on speed — the phone is said to support 100W fast wired charging, allowing for rapid top-ups even with a massive battery.
Designed for Gamers: Dimensity 9400+ & Discrete GPU
Under the hood, the K80 Ultra is powered by the newly enhanced MediaTek Dimensity 9400+ processor, reportedly paired with a custom Xiaomi D2 discrete GPU. Benchmark leaks suggest the phone scored an impressive 3.24 million points on AnTuTu, putting it in the same league as some of the most powerful devices available.
To keep things cool during intense gaming sessions, Redmi is implementing its most advanced cooling system yet — a massive 3D IceLoop vapor chamber. Coupled with Fury Engine 4.0, the setup is optimized for sustained performance without thermal throttling, even during heavy multitasking or long gaming sessions.
Premium Display and Durable Build
The Redmi K80 Ultra features a 6.83-inch LTPS OLED display with a crisp 1.5K resolution and a flat panel design encased in a quad-curved metal frame. It’s built to last, too, with an IP68 water and dust resistance rating and an ultrasonic fingerprint scanner embedded beneath the screen.
Photography and Connectivity
While camera details haven’t been fully confirmed, early indications suggest a triple-lens setup led by a 50MP main sensor, likely optimized for both daylight and low-light photography. The device is expected to offer complete flagship-grade connectivity, including 5G, Wi-Fi, Bluetooth, NFC, and more.
Expected Launch Timeline
The Redmi K80 Ultra is expected to debut in late June or early July 2025 in China. As with past Redmi flagships, there’s speculation that the device — or a slightly modified variant — will launch globally under the Xiaomi 15T Pro name later this year.
