- TECNO will showcase the TECNO Spark Slim at MWC 2025, touting it as the world’s “slimmest phone with a 5,200mAh-plus battery.”
- The phone measures just 5.75mm thick, making it comparable to the rumored Galaxy S25 Edge while packing a significantly larger battery.
- It features a 6.78-inch 3D Curved AMOLED display, a 50MP+50MP dual rear camera setup, and 45W fast charging.
If you’ve been keeping an eye on the smartphone world lately, you’ve probably noticed that “thin is in.” Samsung has already confirmed the existence of its Galaxy S25 Edge, Apple is rumored to be launching an iPhone 17 “Air,” and nearly every foldable phone is trying to shave off extra millimeters. But it turns out thinness isn’t just for premium flagships. TECNO, known for its budget-friendly devices, is throwing its hat into the ring with the TECNO Spark Slim, set to debut at MWC 2025.
The company is touting the device as the “slimmest device with a 5,200mAh-plus battery.” If you’re wondering why it doesn’t just call it the thinnest phone ever, it’s because it isn’t. We’ve seen sub-5mm phones from OPPO and vivo a decade ago, but those devices packed much smaller batteries in line with the trends of that time. TECNO’s claim specifically ties its slimness to battery capacity, which is a notable distinction.
