Infinix Zero 40 5G Review 2025: Is It Worth Buying?

INTRODUCTION

The smartphone industry moves faster than ever. Every month, a new device appears—some marketed as camera champions, others as performance monsters. In this crowded scene, Infinix has been steadily improving, and their latest release, the Infinix Zero 40 5G, aims to shake up the mid-range category.

This phone is clearly designed for users who want a premium look and solid everyday performance without paying flagship prices. With features like a curved AMOLED display, fast charging, and a capable Dimensity chipset, the Zero 40 5G promises to deliver a balanced experience suitable for daily tasks, content consumption, and casual gaming.

But specs on paper don’t always tell the full story.
So the real question is: Is the Infinix Zero 40 5G truly worth buying in 2025, or is it just another mid-range phone disguised behind fancy numbers?

In this full review, we’ll dig deep into its design, display quality, camera performance, battery life, and overall user experience so you can decide if it’s genuinely worth your money.

INFINIX ZERO 40 5G CAMERA REVIEW

The Infinix Zero 40 5G comes with a surprisingly strong camera setup for its price. The rear system includes a 108 MP main sensor, a 50 MP ultra-wide, and a 2 MP depth lens. For a mid-range device, this combination offers a lot of flexibility.

In daylight, the phone captures sharp images with good dynamic range. Colors lean slightly towards a natural tone rather than being overly saturated, which is a good sign for anyone who prefers realistic photography. Landscapes and wide-angle shots maintain decent detail, and the ultra-wide lens doesn’t distort too much around the edges.

At night or in low-light conditions, things become a bit mixed. You’ll definitely see some noise and occasional color inconsistencies. However, switching on Night Mode or using AI enhancements helps brighten the scene and make photos more usable. They’re not flagship-level, but more than adequate for social media posts, stories, or casual sharing.

On the front, the 50 MP selfie camera performs well. Selfies are bright, smooth, and clear, especially in good lighting. Beauty mode is present—as usual with Infinix—and it can soften the skin a bit aggressively if turned up. Video recording supports 4K at 30fps, which is impressive for a phone at this price point.

Overall, the Zero 40 5G offers a capable camera system that’s great for everyday users, social media creators, and anyone who enjoys casual photography.

DISPLAY & DESIGN

One of the first things you’ll notice about the Infinix Zero 40 5G is how premium it looks and feels. The matte-finish rear panel reduces fingerprints, and the curved edges blend nicely into the frame, making the phone comfortable to hold. The overall weight is well-balanced—not so light that it feels cheap, and not so heavy that it becomes tiring during long use. The color options, including classic black, blue, and gradient finishes, add an extra touch of style.

Moving to the display, Infinix has included a 6.78-inch AMOLED panel with a 144Hz refresh rate, and this is easily one of the highlights of the device. The high refresh rate makes scrolling, animations, and app transitions extremely smooth. Whether you’re browsing social media, watching videos, or gaming, the experience feels fluid and responsive.

Brightness levels are strong enough for comfortable outdoor visibility, and the colors are vibrant without looking exaggerated. Viewing angles are wide, too, so watching videos or sharing the screen with someone feels natural.

The only small drawback is the phone’s physical size. Because of the large display and curved edges, one-handed use can sometimes be a challenge, especially if you have smaller hands.

PERFORMANCE TEST

Under the hood, the Infinix Zero 40 5G runs on the MediaTek Dimensity 8200 Ultimate chipset, based on a 4nm process. This chipset is known for offering a good balance of efficiency and power, and that holds here as well.

For everyday tasks—social media scrolling, messaging, video streaming, multitasking—the phone performs smoothly without noticeable lag. Apps load quickly, and switching between them is seamless, especially in the 8GB or 12GB RAM variants.

When it comes to gaming, the phone handles moderate titles with ease. Games like Mobile Legends, Free Fire, and Asphalt 9 run well with high settings. However, for heavier games such as PUBG, Call of Duty, or Genshin Impact, you may notice occasional frame drops or slight warming during long sessions. It’s not severe, but it’s noticeable enough to mention.

Overall, the Zero 40 5G offers a very reliable performance for its price point, especially for users who prioritize daily usability over intense gaming.

BATTERY & CHARGING

The Infinix Zero 40 5G packs a 5000 mAh battery, which is pretty standard for mid-range phones in 2025—but still very reliable. With regular use (social media, YouTube, messaging, occasional gaming), it easily lasts a full day. Even heavy users should get through most of the day without charging.

The charging experience is impressive, thanks to 68W fast charging. You can go from 0% to around 80% in roughly 35 minutes, making it extremely convenient for users on tight schedules. The phone also supports reverse charging, letting you power up another device if needed.

One thing to note: the battery drains a bit faster when the display is kept at the full 144Hz refresh rate. Switching to an adaptive or lower refresh rate improves battery life noticeably.

PRICE & AVAILABILITY

In Pakistan, the Infinix Zero 40 5G is priced at around Rs. 89,999, which is approximately USD $375 through official sellers. Online platforms and imported variants may cost slightly higher—sometimes up to Rs. 114,990, depending on store policies, color options, and warranty coverage.

The phone is available across most major Pakistani cities, though stock can vary, especially for certain colors or RAM/storage configurations.
