Lighter than the iPhone Air
With its skinny body, the TECNO Spark Slim was among the concepts that had big impressions during the Mobile World Congress (MWC) 2025. Ironically, it's the phone's ultra-thin design that catches the eye, measuring just 5.93mm. TECNO claims that the Spark Slim is the world's slimmest 3D-curved smartphone.

Obviously, the device is light. At 155 grams, it's even lighter than the iPhone Air which weighs 165 grams. Despite its barely-there build, the TECNO Spark Slim feels solid and dependable. In the durability department, it checks the essential boxes: an IP64 rating for dust and water resistance and a Corning GG7i glass cover with double-layer protection to guard against accidental slips and drops.

Curved screen on a budget
Curved displays were once a luxury reserved for flagship phones, but are now becoming more common on entry-level smartphones. The TECNO Spark Slim embraces this trend, boasting not only a beautifully curved panel but also a vibrant AMOLED screen. With a 6.78-inch display delivering 1.5k resolution, up to 4500 nits peak brightness, 144Hz refresh rate, and Pro XDR support, it offers premium viewing for an entry-level price.

Mood Light design
It's given that the TECNO Spark Slim comes with a number of AI features, but a unique function on the device also akin to robots comes in the form of its Mood Light. Upon first glance, it reminded us of the beloved animated character Baymax.

TECNO brings this to life with a playful touch on the Spark Slim's camera bar, which resembles a pair of eyes. It lights up for notifications, incoming calls, while charging, or whenever the device's voice assistant is activated.
Big battery on a slim build
TECNO managed to insert a large-capacity battery on the thin body of the TECNO Spark Slim with a 5,160mAh power that's supported by 45W Super Charging. Plus, it can be used as a powerbank with its 10W Wired Reverse Charging feature.

A photography buddy
A 50-megapixel rear lens serves as the main camera for the TECNO Spark Slim while a 13-megapixel shooter takes on selfies. There could be a compromise especially with a single camera but in its own league, the TECNO Spark Slim can capture social media-ready photos.
