In a world dominated by flagship smartphones that command a premium, Infinix continues to prove that budget devices can still deliver a flagship-like experience. The newly launched Infinix Zero 40 4G is a testament to this belief, offering a compelling mix of performance, AI features, powerful cameras, and a premium design all for a price that won’t leave your wallet hurting.
With this article, we’ll take a deep dive into the Infinix Zero 40 4G specifications, unbox what’s inside, explore the real-world performance, test the camera capabilities, and highlight the practical AI tools that make this phone truly stand out.
Unboxing and First Impressions
The Infinix Zero 40 4G arrives in a surprisingly well-equipped box. Unlike most competitors, Infinix includes everything you need: a 45W fast charger, USB-A to USB-C cable, a vegan leather MagCharge case, a SIM ejector tool, a tempered glass screen protector, and even a complete kit to apply it. Right off the bat, this gives the Zero 40 an edge in terms of value.
Premium Design and Display Experience
The phone feels sleek and well-built in the hand, measuring 164.3 x 74.6 x 7.7 mm and weighing just 180g. Its curved edges and glass back offer a luxurious feel uncommon in this price range. Protected by Corning Gorilla Glass 5, it’s both durable and elegant. The design also includes an IP54 rating, meaning it can withstand dust and splashesa practical addition.
Now, let’s talk about the display. The Infinix Zero 40 4G features a 6.78-inch AMOLED panel with a resolution of 1080 x 2436 pixels, offering vivid color and deep contrast. It supports a 120Hz refresh rate and reaches 1300 nits of brightness (HBM), making it excellent for both indoor and outdoor viewing. While Netflix doesn’t support HDR on this device, 4K HDR videos on YouTube play beautifully, enhanced by the loud, dual JBL-tuned speakers.
A Closer Look at the Cameras
Arguably one of the most impressive aspects of the Infinix Zero 40 4G specifications is its camera system. On the back, there’s a triple-camera setup:
- 108MP main sensor with OIS and PDAF
- 50MP ultrawide sensor with a 120° field of view
- 2MP depth sensor
Photos are crisp and vibrant, with natural background blur and solid HDR processing. The ultrawide sensor does a great job in daylight, although the colors could use a touch more saturation. Even more impressive is the 50MP front camera, which delivers high-quality selfies with excellent skin tones and background separation.
Both the front and rear cameras support 4K 60fps video recording, a rare feature in this price segment. The portrait video mode is particularly smooth, offering excellent subject separation without background glitches, even in the front camera. Additional options like Ultra Steady and Ultra Steady Pro modes help deliver stabilized footage in motion-heavy scenes.
AI Video Editing and Smart Features
One standout feature is the AI Vlog mode. It allows you to shoot multiple short video snippets and then uses AI to compile them into a stylized vlog. You can choose from various templates or go freestyle. It’s perfect for content creators or social media enthusiasts who want polished video output with minimal editing effort.
Infinix also collaborated with GoPro, allowing users to link their GoPro device directly to the phone’s native camera app. This is incredibly useful for travel vloggers or extreme sports users who want more control over their footage.

Raw Power: Performance and Gaming
Under the hood, the Infinix Zero 40 4G is powered by the MediaTek Helio G100, a 6nm chipset with an octa-core CPU (2x Cortex-A76 @ 2.2GHz + 6x Cortex-A55 @ 2.0GHz) and Mali-G57 MC2 GPU. Paired with 8GB LPDDR4X RAM (expandable via virtual RAM), and storage options of 256GB or 512GB UFS 2.2, this phone is more than capable of handling demanding tasks.
Benchmarks reveal an impressive score of 950,000+ on AnTuTu. But benchmarks aside, real-world performance is where it truly shines. Whether it’s editing videos, multitasking between heavy apps, or playing graphics-intensive games like BGMI at 90 FPS, the phone handles it all without breaking a sweat.
Another bonus is the Bypass Charging 2.0 feature. While gaming and charging, power is directed to the chipset instead of the battery, preventing heat build-up just like in gaming laptops. This is a major win for mobile gamers.
Battery Life and Charging
The device packs a 5000mAh battery, which easily lasts a full day even with heavy usage, thanks to the efficiency of the Helio G100 chip and AMOLED display. The 45W wired charging gets you 50% battery in just 25 minutes, and it also supports reverse wired charging and 10W reverse wireless charging are at this price point.
Software and AI Capabilities
The phone runs Android 14 with XOS 14.5 skin on top, and it comes with a promise of two major Android updates and three years of security patches.
But what makes the Infinix Zero 40 truly unique is its suite of built-in AI features:
- AI Eraser: Remove unwanted objects from your photos offline.
- Smart Cutouts: Tap and hold on people in photos to make stickers.
- Ask AI: Generate or optimize text (like emails) directly in your apps.
- FX Assistant: A voice assistant powered by ChatGPT, capable of summarizing articles, opening apps, and performing phone functions via voice.
While useful, there’s room for improvement in terms of conveniencesome tasks require multiple steps,
Final Thoughts: Is It Too Good to Be True?
Looking at the Infinix Zero 40 4G specifications, it’s hard to believe this phone is priced under €250. It offers features that are often found in devices twice the price:
- Flagship-grade 108MP and 50MP cameras
- 4K 60fps video on front and rear
- AI tools that add real value
- Durable design with premium finish
- Powerful gaming performance with smart battery management
- Useful accessories included in-box
Yes, it’s not perfect. The ultrawide camera needs better color tuning, and the AI assistant could be more intuitive. But these are minor trade-offs in what is otherwise an incredibly well-rounded package.
For creators, gamers, and tech enthusiasts on a budget, this is arguably one of the best 4G smartphones of 2024. If you’re someone who needs high performance, great cameras, and innovative AI features, the Infinix Zero 40 4G is worth serious consideration.
