Ultra-Thin 5G Smartphone: The Indian smartphone market is buzzing with anticipation for the Tecno Spark Slim, potentially the best thin smartphone India has ever seen. With its record-breaking 5.75mm profile, this ultra thin phone with good battery life promises to challenge premium devices while maintaining affordability for Indian consumers.
World Thinnest 5G Phone Features and Price
The Tecno Spark Slim price in India is expected around ₹80,000, positioning it as a 5G phone under 80000 that doesn’t compromise on premium features. According to official specifications revealed at Mobile World Congress 2025, this thin phone 2025 sets new engineering standards.
What makes the Tecno Spark review particularly interesting is how they’ve managed to pack flagship features into such a slim profile. The company achieved this using an innovative 4.04mm thick battery design, delivering 5,200mAh capacity – impressive for any ultra-thin 5G smartphone.
The Tecno Spark camera setup features dual 50MP rear sensors and a 13MP front camera, making it competitive in the photography segment. With specifications including a 6.78-inch curved AMOLED display, 144Hz refresh rate, and 1.5K resolution, this 5G smartphone India launch could reshape the premium market.

Tecno Spark Slim Battery Life and Performance
The Tecno Spark Slim battery performance could be a game-changer. Most ultra thin phone with good battery combinations fail because manufacturers sacrifice capacity for design. However, this Tecno mobile phone promises all-day usage despite its razor-thin profile.
They’re only revealing “octa-core CPU” in their official communications, which raises questions about real-world performance. For a smartphone launch India targeting premium buyers, processor details matter significantly.
I’m particularly curious about thermal management. Thin phones often struggle with heat dissipation, affecting both performance and Tecno Spark Slim battery longevity. The stainless steel frame might help, but real-world testing will reveal the truth.
Tecno vs Samsung vs Apple Comparison
This Tecno vs Samsung comparison gets interesting when you consider specifications. The Spark Slim is supposedly even thinner than Samsung’s Galaxy S25 Edge (5.75mm vs 5.8mm), though that minimal difference might not matter practically.
Best Thin Smartphone India Contenders
- Tecno Spark Slim: 5.75mm, ₹80,000, 5,200mAh battery
- Samsung Galaxy S25 Edge: 5.8mm, expected ₹90,000+
- iPhone 17 Air: Thickness TBD, expected ₹100,000+
The pricing strategy around ₹80,000 makes this 5G phone under 80000 attractive for premium features without flagship pricing.
