Xiaomi Redmi K80 review: specs, battery & used prices

Summary

The Xiaomi Redmi K80 is Xiaomi's 2024 performance-value flagship: a Snapdragon 8 Gen 3, a 6,550 mAh battery, and a 1,800-nit OLED at a price the name brands rarely reach — the 12/256 GB variant is $429 new, and used units trade around $381. The sample is thin (a handful of sales), but the hardware-per-dollar story is already clear.

Display and design

The 6.67-inch OLED refreshes at 120 Hz with a 1,800-nit peak — screen quality 75/100 on our axis, among the stronger panels in its price class. At 206 g with IP68 sealing, it reads as a conventional flagship slab rather than a niche device; compactness sits at 77/100.

Performance

The Snapdragon 8 Gen 3 is the same silicon as far costlier 2024 flagships, and our gaming score of 54/100 reflects genuinely strong current-gen 3D performance. Everyday responsiveness scores 90/100. The K line's premise — flagship chip, restrained everything else — is intact here.

Camera

The camera is the deliberate economy: a 50 MP stabilised main sensor with an 8 MP ultrawide, no telephoto, video to 8K. Our camera score of 32/100 is honest about the single-lens setup — main-sensor results are dependable in good light, and the zoom conversation ends quickly.

Battery and charging

The 6,550 mAh cell scores 71/100 on battery life, comfortably a two-day battery for moderate use, and 90 W wired charging scores 71/100 — a rare pairing of huge capacity and fast top-ups at this price.

Verdict

At $429 new or around $381 used, the K80 is a rationalist's flagship: top-tier silicon, an exceptional battery, and a bright IP68 panel, with the camera kept deliberately simple. Used-market samples remain scarce, so patience may be needed. The Xiaomi 14 adds a proper Leica-tuned camera system for more money; the OnePlus 13R is the closest mainstream alternative with similar endurance priorities.
