Infinix Zero 40 5G Review

The Infinix Zero 40 5G arrives as a compelling proposition in 2024 — packing a 144 Hz curved AMOLED display, a 108 MP main camera with OIS, 5G connectivity, wireless charging, and more. With its starting price around ₹ 27,999 (~USD 340) in India, the phone invites attention from budget-conscious buyers who want high-end extras. But does it deliver on that promise? Infinix’s ambition is clear and the hardware impressive, but the execution shows both strengths and areas for caution.

Design & Build: Premium Feel, Mid-Tier Finishes

At 195 g and measuring 164.3 × 74.8 × 7.9 mm, the Zero 40 5G delivers a substantial yet manageable handset footprint. GSMArena+2Kowatek Solar LTD+2 The curved glass-front (6.78″) flowing into subtly shaped edges helps craft a premium look. The rear design features a large circular camera module and a two-tone finish (especially in “Violet Garden”) that stands out. Gadgets 360+1 Infinix also gives the phone an IP54 rating for dust and splash resistance — a rare inclusion at this price. Gadgets 360+1

However, while the phone looks premium, some materials still betray its price point: plastic or mixed-materials rather than full metal glass build, and the durability under long use remains less proven than top-tier flagships. That said, for what you get, the build is a strong mid-range showing.

Display: Smooth, Big, and Immersive

The highlight here is the 6.78″ AMOLED panel with a 144 Hz refresh rate, 1 billion colour support, and up to ~1300 nits peak brightness. Kowatek Solar LTD+2Gadgets 360+2 The 144 Hz (and touch sampling up to 360Hz) gives exceptionally smooth scrolling, UI animations and gaming responsiveness. One reviewer aptly called this display “downright a treat”. gadgetryhq.com

There are some caveats. The panel is FHD+ (not QHD), and the brightness under direct sunlight may be less than truly flagship levels. Gadgets 360 Still, for daily use, media consumption and even gaming at high refresh, this display punches well above the price tier.

Performance: Strong Chip with Some Thermal Trade-Offs

The Infinix Zero 40 5G is powered by the MediaTek Dimensity 8200 Ultimate chipset (4 nm), paired with up to 12 GB RAM and up to 512 GB UFS 3.1 storage. Gadgets 360+1 In benchmarking and real-world use, it handles everyday tasks, multitasking and moderately heavy gaming with ease. Gadgets 360

Gaming performance is competent — titles like Asphalt or COD Mobile run smoothly — though some reports show the phone heating during longer sessions or when recording 4K video. Reddit+1 So while it’s far from underpowered, power users should be aware of the limitations in thermal and sustained load scenarios.

Camera System: Big Numbers, Some Compromises

On paper, the camera package is impressive: 108 MP main (OIS), 50 MP ultra-wide (120°), and 2 MP depth sensor; 50 MP front camera as well. GSMArena+1 Infinix emphasises its 4K@60fps recording on both front and rear cameras. Gadgets 360

In daylight conditions the camera delivers solid results — sharp detail, good colour vibrancy, decent HDR. Gadgets 360 But reviewers also note inconsistencies: colour saturation varies between lenses, low-light performance is average, and the ultra-wide and tele outcomes fall behind some rivals. myktmedia.com Video stabilisation at 4K@60fps is limited. Gadgets 360

Bottom line: The camera system is good for the money and stylish enough for social use, but if photography is your priority, it’s not yet flagship-class.

Battery Life & Charging: Good, But Not Class-Leading

Equipped with a 5,000 mAh battery, the Zero 40 5G offers about a full day of use with moderate to heavy tasks — though under 144 Hz refresh and heavy gaming, runtimes drop. A test showed ~14 hours under video loop at 144 Hz. Gadgets 360 Charging is competitive: 45W wired (full charge ~1h10min in one test) and even 20W wireless support. Gadgets 360+1

So while you’re well covered for a day of use, the endurance is not quite top tier — a trade-off given the high refresh display and mid-tier battery hardware.

Software & Features: Rich Extras with Some Flaws

The phone ships with Android 14 (XOS 14.5) and Infinix’s custom UI layer. Key extras include dual stereo speakers (JBL tuned), IR blaster, NFC (regional), curved display, wireless + reverse charging and IP54 rating. gadgetryhq.com

On the flip side: Software update policy and long-term support appear weaker than premium rivals — some users already noted delays in patches. Reddit Also, the UI has been described as less polished compared to top competitors. gadgetryhq.com

Verdict: Excellent Value with Smart Expectations
