TECNO Unveils SPARK Slim, the World’s Thinnest Curved-Screen Smartphone at 5.93mm
TECNO, the AI-focused smartphone brand, has officially introduced the SPARK Slim, setting a new global record as the thinnest curved-screen smartphone ever made at just 5.93mm.
Breaking industry norms, the SPARK Slim combines its ultra-sleek profile with a powerful 5160mAh battery, an advanced thermal system, and military-grade durability. The launch challenges the long-held assumption that ultra-thin smartphones must sacrifice performance or battery life.
With its expressive aesthetics, aerospace-grade materials, and AI-driven capabilities, the SPARK Slim delivers a premium yet youthful smartphone experience at a competitive and accessible price point.
A Leap Forward in Slim Smartphone Engineering
TECNO achieved the SPARK Slim’s industry-leading thinness using its proprietary honeycomb space-stacking technology. This approach improves internal space efficiency by 12% and significantly shrinks eight major components—including the battery, motherboard, and cooling system—while maintaining overall structural integrity.
Despite its ultra-thin build, the device houses a 5160mAh high-density lithium cobalt oxide battery, capable of delivering up to 24.8 hours of Day of Use (DOU). Charging features include:
- 45W fast charging
- 10W reverse charging
- Bypass charging to minimize heat during gaming and intensive usage
The battery is also designed to resist swelling and degradation over time, reinforcing TECNO’s claim that slim devices can still offer reliable, long-lasting endurance.
Efficient Cooling and Smooth Performance
To sustain performance within its compact form factor, the SPARK Slim features a sophisticated cooling system made up of:
- 0.3mm ultra-thin vapour chamber
- 1800W/m·K high-conductivity graphite layer
- 24,532mm² thermal dissipation structure
This cooling setup ensures stable temperatures during fast charging, multitasking, and prolonged gaming sessions.
At the core of the device is the MediaTek Helio G200 chipset, engineered for smooth operation and energy efficiency. The smartphone also carries TÜV certification for up to five years of fluency, offering dependable long-term performance.
Military-Grade Strength in an Ultra-Slim Body
Although exceptionally thin, the SPARK Slim is built with durability in mind. Key protective features include:
- 0.36mm aerospace-grade fibreglass back panel, delivering 300% more strength and 200% greater flexibility than conventional materials
- Corning® Gorilla® Glass 7i for enhanced display protection
- IP64-rated protection against dust and water splashes
Together, these elements ensure the device can withstand daily wear while maintaining its elegant form.
Ultra-Slim Design with Personal Expression
The TECNO SPARK Slim is offered in two refined colour options:
- Slim White
- Cool Black
Weighing only 156g, the phone features an ultra-narrow curved frame that feels both lightweight and comfortable in hand.
A unique design highlight is the Mood Light system on the rear panel—two expressive circular light elements that display animated effects for:
- Charging status
- Power on and off
- Incoming calls
- Notifications
- Ella voice assistant activation
This interactive lighting feature adds personality and flair, making the SPARK Slim especially appealing to Gen Z and style-conscious users.
Premium Display and Immersive Entertainment
The SPARK Slim boasts a vibrant 1.5K curved display engineered for immersive viewing and smooth interaction. Display highlights include:
- Peak brightness of up to 4,500 nits
- 144Hz refresh rate for ultra-smooth visuals
- Sharp visibility even under direct sunlight
These features ensure fluid scrolling, vivid colours, and excellent clarity across all lighting conditions.
Audio performance is enhanced by Dolby dual stereo speakers, delivering rich, balanced sound for gaming, streaming, and music playback.
AI-Driven Productivity and Smart Connectivity
The SPARK Slim integrates TECNO AI to boost productivity and creativity, offering features such as:
- Real-time language translation
- AI-powered document summarization
- Photo repair and image enhancement
The device also supports Touch Transfer, enabling instant sharing of photos, videos, and files between TECNO devices via a simple NFC tap.
For users in low-network or remote locations, TECNO FreeLink technology allows Bluetooth-based messaging and two-way calling even without cellular connectivity.
Redefining the Ultra-Slim Smartphone Category
With the SPARK Slim, TECNO proves that ultra-slim design, durability, and performance can coexist. As the world’s thinnest curved-screen smartphone, it sets a new benchmark in mobile engineering while delivering practical, everyday usability.
The TECNO SPARK Slim emerges as a stylish yet functional choice for users who value innovation, individuality, and cutting-edge design—redefining what modern smartphones can achieve.
