TECNO to Launch World’s Slimmest Smartphone with Just 5.7mm Thickness, Price May Be Around ₹80,000

Smartphone brand TECNO is again making headlines for innovation. Reports suggest that the company is preparing to launch the world’s thinnest smartphone in India. The phone may have just 5.7mm thickness (0.57cm), making it even slimmer than devices like the Samsung Galaxy S25 Edge.

Launch Timeline

If leaks are to be believed, this upcoming TECNO smartphone may be unveiled during October 2025, around the Diwali season in India. While the official name of the device is yet to be revealed, its design and slimness are already creating buzz across the industry.

Expected Price

Since the device is aimed at the flagship segment, the price is expected to be around ₹80,000. This clearly shows TECNO is positioning it for premium markets and high-end smartphone buyers who value both performance and ultra-thin design.

Possible Specifications and Features

Although TECNO has not confirmed the final specs, leaks point towards high-end hardware including:

• Processor: MediaTek Dimensity 9400+
• OS: Android 16 out of the box
• Battery: 6,000mAh or higher capacity
• Charging: 90W superfast charging support
• Display: Quad-curved AMOLED, 6.3 to 6.5-inch size
• Design: Only 5.7mm thick with ultra-slim and premium build

Reference from TECNO’s Previous Concept – Spark Slim

Earlier this year at MWC 2025, TECNO showcased its Spark Slim Concept Phone. The concept device had a thickness of just 5.75mm, giving a glimpse of TECNO’s direction towards ultra-slim smartphones.

Key highlights of Spark Slim concept:

• 6.78-inch curved AMOLED display with 144Hz refresh rate and 4,500 nits peak brightness
• Dual 50MP rear cameras
• 5,200mAh battery with just 4.04mm thin cell design

It’s highly expected that TECNO’s upcoming commercial model will be based on these design concepts while offering even more powerful hardware.

Conclusion

If current leaks are accurate, TECNO is all set to grab global attention with the launch of the world’s slimmest 5G smartphone at just 5.7mm thickness. With a large 6,000mAh battery, flagship-level Dimensity 9400+ processor, Android 16 OS, and 90W fast charging, this smartphone could redefine the thin-and-powerful category.

All eyes are now on Diwali 2025, when this futuristic TECNO smartphone is expected to hit Indian markets as one of the world’s most unique ultra-slim 5G devices.
