Read our comprehensive Infinix ZERO 40 5G review covering design, display, camera, performance, battery, software, pricing, pros & cons, and final verdict.
Category: Premium Mid-Range Smartphone
Quick Verdict
The premium mid-range smartphone market has evolved rapidly, with consumers expecting flagship-inspired design, capable cameras, smooth displays, fast performance, and long-lasting batteries without paying flagship prices. Infinix has steadily moved beyond the entry-level segment, and the Infinix ZERO 40 5G represents its most refined effort to compete with established brands in the ₹25,000–₹35,000 price range.
The ZERO 40 5G combines a curved 6.78-inch 144Hz AMOLED display, the MediaTek Dimensity 8200 Ultimate chipset, a 108MP OIS primary camera, a 50MP ultra-wide camera, a 50MP autofocus selfie camera capable of 4K video, a 5000mAh battery, and support for 45W wired fast charging as well as wireless charging. JBL-tuned stereo speakers and Android 14 with XOS 14.5 complete a feature set rarely found together in this price segment.
What makes the ZERO 40 5G particularly interesting is its emphasis on content creation. High-resolution front and rear cameras, premium curved display, wireless charging, and stylish design target users who prioritize photography, video, and social media alongside everyday productivity.
It isn’t the fastest gaming smartphone in its class, and some competitors offer longer software support or larger batteries. However, for buyers seeking an attractive all-rounder with premium features, the Infinix ZERO 40 5G delivers a surprisingly complete package.
Digital Plaza Verdict
The Infinix ZERO 40 5G successfully bridges the gap between affordability and premium experience. It offers flagship-inspired design, capable cameras, smooth performance, and modern features that make it one of the most compelling premium mid-range smartphones from Infinix to date.

Design & Build Quality
The Infinix ZERO 40 5G demonstrates how far the brand has progressed in industrial design. Rather than relying on flashy aesthetics alone, Infinix has created a smartphone that feels refined, modern, and competitive with devices from more established manufacturers.
The curved AMOLED display seamlessly blends into the frame, creating an immersive front profile with slim bezels. The rear panel is cleanly designed, while the camera module is integrated in a way that balances visual appeal with practicality.
Despite its premium appearance, the device remains comfortable to hold for extended periods. Weight distribution is balanced, button placement is ergonomic, and the matte finish helps minimize fingerprints on darker color options.
Attention to detail extends to the JBL-tuned stereo speakers, premium finish options, and overall fit and finish. While the device may not match the materials of ultra-premium flagships, it clearly exceeds expectations for its price category.
From a design perspective, the ZERO 40 5G is one of Infinix’s most polished smartphones to date.
