Redmi’s upcoming K80 Ultra is shaping up to be a performance-focused flagship, but even before its official launch in China, a detailed teardown has given us an early look at what’s under the hood. And while the hardware is undeniably impressive, there are a few trade-offs that might give potential buyers pause.
A teardown by WekiHome shows the phone’s internal design and reveals a focus on thermal performance, gaming, and display quality. At the front is a 6.83-inch 1.5K LTPS OLED panel from TCL with a 144Hz refresh rate, M9 material, and DC dimming support—designed for smooth visuals without flicker, even at low brightness levels.
Under the hood, the K80 Ultra runs on MediaTek’s new Dimensity 9400+ chip, paired with Micron LPDDR5X RAM and Samsung UFS 4.1 storage—hardware that makes it a serious contender for mobile gamers. The thermal setup is extensive: it includes a dual-layer stainless-steel vapor chamber, 11,400mm² of thermal film, a 6,800mm² graphite sheet, and multiple layers of thermal paste. In testing, the phone stayed below 41°C while running heavy titles at 120fps, drawing only around 4.3W of power.
Audio and haptics are also getting special attention. The K80 Ultra uses coaxial dual speakers from AAC Technologies and includes a large 601.47mm³ haptic motor to provide stronger tactile feedback. Powering everything is a 7,410mAh battery with support for 100W wired charging. Redmi is bundling a 120W charger in the box, and the device also reportedly supports “Bypass Charging Plus”, which helps reduce heat during intensive use and preserve battery in the long run. Redmi claims the phone can last up to 2.26 days on a single charge.
Still, there are a few noticeable omissions. For starters, there’s no wireless charging—a feature that’s become standard in many flagship-level devices. And while the USB-C port supports fast charging, it’s limited to USB 2.0 speeds for data transfer, which tops out at just 480Mbps. That’s a step down compared to models like the Xiaomi 15 Pro, which support USB 3.2.
The phone sports a flat, CNC-machined aluminum frame and a fiberglass back, weighing in at 219g. It also carries an IP69 rating for dust and water resistance.
