SPARK Slim: TECNO Launches World’s thinnest curved-screen smartphone

The SPARK Slim is priced at KSh 27,999 before VAT.

Staying true to the SPARK series’ youthful, fashion-forward identity, the SPARK Slim pairs a lightweight frame with a sleek 3D-curved profile for a refined in-hand experience.

An aerospace-grade fiberglass rear cover offers improved strength while maintaining a thinner profile, and the handset comes in bold color options designed to appeal to creative, style-driven users. A unique Mood Light feature on the rear adds a playful touch, reinforcing TECNO’s focus on expressive design.

At 5.93mm, the SPARK Slim becomes the world’s thinnest curved-screen handset—a feat achieved through TECNO’s honeycomb space-stacking technology. This structural innovation optimizes 12% of the internal layout, enabling the reduction of eight key components, including the motherboard, cooling system, and battery module, without compromising overall durability.

Despite its slim silhouette, the SPARK Slim’s high-density lithium cobalt oxide battery delivers up to 24.8 hours of typical daily use. It supports 45W fast charging, 10W reverse charging, and bypass charging to reduce heat during heavy usage. TECNO says the battery is engineered to resist swelling, ensuring long-term reliability.

The phone incorporates a 0.3mm ultra-thin vapor chamber and a high-conductivity graphite layer rated at 1800W/m·K, creating a 24,532mm² cooling system that helps maintain stable performance during gaming, charging, and multitasking.

Powering the device is MediaTek’s new Helio G200 chipset, designed to balance performance with energy efficiency. TECNO notes that the device’s fluency is TÜV-certified for up to five years, promising users long-term smooth operation.

Durability remains a core focus of the SPARK Slim. Its 0.36mm aerospace-grade fiberglass back cover offers 200% more flexibility and triple the strength of conventional materials, while still being noticeably thinner at 0.19mm.

The display is protected by Corning Gorilla Glass 7i, and the device carries an IP64 rating, making it resistant to dust and light water exposure.

A signature feature of the device is its dual-circle Mood Light module on the rear. These animated light elements react to various scenarios—including powering on, charging, incoming calls, notifications, and voice assistant activation—expressing different “emotions” through dynamic lighting patterns.

TECNO positions this as a fun design detail that adds charm to everyday interactions.
