Innovative technology brand TECNO has officially launched the SPARK Slim, setting a new global benchmark as the world's slimmest 3D-curved smartphone. Measuring an incredible just 5.93mm thick, this groundbreaking device was announced on November 19, 2025, challenging conventional smartphone design limitations.
Revolutionary Design Meets Uncompromising Performance
The SPARK Slim achieves its remarkable thinness through TECNO's proprietary honeycomb space stacking technology, which optimizes 12% of internal space and slims eight core components. Despite its ultra-thin profile, the device packs a massive 5160mAh high-density lithium cobalt oxide battery that delivers up to 24.8 hours of daily use.
The smartphone supports 45W fast charging, 10W reverse charging, and bypass charging technologies. To maintain performance during heavy usage, TECNO integrated a sophisticated cooling system featuring a 0.3mm ultra-thin vapor chamber and high-conductivity graphite layer with thermal performance of 1800W/m·K.
Military-Grade Durability in Ultra-Slim Form
Despite its extreme slimness, the SPARK Slim doesn't compromise on durability. The device features a 0.36mm aerospace-grade fiberglass back cover that's 0.19mm thinner than conventional materials while improving strength by 300% and flexibility by 200%.
The smartphone has passed military industry certification and comes with Corning Gorilla Glass 7i protection and an IP64 rating against dust and water. Weighing approximately 156g with an ultra-narrow frame, the device offers both elegance and practical durability for everyday use.
Interactive Features and Premium Experience
The SPARK Slim introduces an innovative Mood Light design on the back, featuring two circular "eyes" that display playful light animations during various scenarios like charging, incoming calls, and notifications. This interactive element allows Gen Z users to express their individuality through their device.
The device boasts a 1.5K high-resolution curved display with 4500 nits peak brightness and 144Hz refresh rate, ensuring vivid visuals even in bright outdoor conditions. Powered by the new MediaTek Helio G200 chipset with TÜV-certified fluency for up to five years, the smartphone promises long-term performance stability.
TECNO has integrated advanced AI capabilities including real-time translation, document summarization, and AI photo repair. The device also features Touch Transfer for instant file sharing via NFC and FreeLink technology for Bluetooth-based messaging and calls without cellular coverage.
Available in Slim White and Cool Black color options, the SPARK Slim represents TECNO's commitment to pushing technological boundaries while maintaining practical functionality. This launch demonstrates that ultra-slim design and powerful performance can indeed coexist, offering Nigerian consumers a premium smartphone experience that defies traditional compromises.
