TECNO Launches SPARK Slim: World’s Thinnest Curved-Screen Smartphone at 5.93mm
AI-driven smartphone brand TECNO has officially launched the TECNO SPARK Slim, the world’s slimmest curved-screen smartphone, measuring an ultra-thin 5.93mm. Despite its sleek profile, the SPARK Slim packs a large 5160mAh battery, advanced cooling technology, and military-grade durability, challenging the long-held belief that slim phones compromise on performance or endurance.
With its expressive design, aerospace-grade materials, and AI-enhanced features, the SPARK Slim delivers a premium, youth-focused experience at a highly accessible price point.
A Breakthrough in Smartphone Slimness and Engineering
The SPARK Slim achieves its record-breaking thinness through TECNO’s innovative honeycomb space stacking technology, which optimises internal layout by 12% and reduces the size of eight core components, including the battery, motherboard, and cooling system, while maintaining structural strength.
Even with its ultra-thin frame, the device houses a 5160mAh high-density lithium cobalt oxide battery that delivers up to 24.8 hours of Day of Use (DOU). It supports:
- 45W fast charging
- 10W reverse charging
- Bypass charging for reduced heat during gaming and heavy tasks
The battery is engineered to resist swelling and deliver long-term stability, proving that slim design can still offer exceptional endurance.
Advanced Cooling and Performance
To maintain performance in such a minimal profile, the SPARK Slim integrates:
- A 0.3mm ultra-thin vapour chamber
- A 1800W/m·K high-conductivity graphite layer
- A 24,532mm² thermal system
This setup keeps the device cool during charging, multitasking, and gaming.
Powering the device is the MediaTek Helio G200 chipset, optimised for smooth performance and energy efficiency. It comes with TÜV-certified fluency for up to five years, offering users reliable long-term performance.
Stronger Than It Looks: Military-Grade Durability
Despite its extreme slimness, the SPARK Slim does not compromise on durability. It features:
- A 0.36mm aerospace-grade fibreglass back cover, 300% stronger and 200% more flexible than standard materials
- Corning® Gorilla® Glass 7i for screen protection
- IP64 certification, ensuring resistance to dust and water
These features combine to deliver all-around resilience suitable for daily use.
Slim, Stylish, and Designed for Individual Expression
The SPARK Slim comes in two elegant colourways:
- Slim White
- Cool Black
Weighing just 156g, the device features an ultra-narrow curved frame that offers a refined, comfortable grip.
A standout design feature is the new Mood Light system on the back, two expressive circular “eyes” that display playful emotions and animated lighting effects for events such as:
- Charging
- Power on/off
- Incoming calls
- Notifications
- Ella voice assistant activation
This interactive lighting transforms functional alerts into a unique style element, making the device especially appealing to Gen Z users.
Premium Visuals and Entertainment Experience
The SPARK Slim features a 1.5K curved display with:
- 4500 nits peak brightness
- 144Hz refresh rate
- Vivid and sharp outdoor visibility
This ensures smooth scrolling, immersive viewing, and crisp clarity in any lighting condition.
Sound quality is enhanced with Dolby dual stereo speakers, offering richer audio for entertainment.
AI-Powered Productivity and Seamless Connectivity
The device integrates TECNO AI, enabling:
- Real-time translation
- Document summarization
- AI photo repair
It also supports Touch Transfer, allowing instant sharing of images, videos, and files between TECNO devices with a simple NFC tap.
For remote or offline environments, the SPARK Slim includes TECNO’s FreeLink technology, enabling Bluetooth-based messaging and two-way calls without cellular coverage.
A New Standard for Ultra-Slim Smartphones
With the SPARK Slim, TECNO demonstrates that slim, stylish, and powerful can coexist. As the world’s thinnest curved-screen smartphone, the device pushes the boundaries of mobile engineering while delivering robust performance, durable design, and AI-driven functionality.
It represents a premium yet practical choice for users who value individuality, innovation, and ultra-slim aesthetics, redefining what a modern smartphone can be.
