Infinix Zero 40 5G Full Specification: Impressive Cameras, High Performance & Premium Design

The Infinix Zero 40 5G uses an AMOLED display  and getting AMOLED at this price is genuinely something worth noting. AMOLED means each pixel lights itself individually, so when something on screen is black, those pixels simply switch off entirely. The result is true blacks, naturally vibrant colors, and noticeably better battery efficiency during dark-themed apps compared to LCD screens. It sits at 6.78 inches with a 1080 x 2436 pixel resolution, which keeps everything looking clean and sharp without overworking the battery.

It reaches 1300 nits in high brightness mode. That number matters in real life  step outside on a bright afternoon and 1300 nits is enough to keep the screen readable without constantly shielding it with your hand. It is not at the extreme end like some flagships pushing 2000 nits or beyond, but for a mid-range phone it handles outdoor visibility confidently. Indoors it auto-adjusts to comfortable levels so your eyes are not being punished while scrolling at night.

The infinix Zero 40 5G runs on the MediaTek Dimensity 8200 built on a 4nm process. This chip sits in the upper mid-range tier and in daily use it genuinely earns its place there  apps open quickly, the system stays fluid under normal multitasking, and popular games like Free Fire and BGMI run well at decent settings. The single performance core clocks up to 3.1 GHz for demanding single-core tasks while the remaining cores handle everything else efficiently. The 4nm process keeps heat and power consumption in a reasonable range. It will not compete with flagship chips, but for what most people actually do with a phone day to day it is more than capable

The Zero 40 5G uses LPDDR5X RAM paired with UFS 4.0 storage — both of which are fast, modern standards that you would normally expect to find in phones costing significantly more. LPDDR5X RAM means multitasking feels smooth and apps stay loaded in the background without constantly refreshing when you return to them.

The main rear camera is 108MP  and the pixel count is backed by a Samsung sensor which matters because it means the image processing foundation is solid. In good daylight the 108MP sensor captures detailed, well-exposed shots with natural colors. You can crop heavily into a photo and still retain usable detail, which is genuinely practical for travel and outdoor photography. There is also a 50MP secondary camera and a 2MP depth sensor rounding out the triple setup. 

The front camera is a standout 50MP shooter  and that is not just a number for the spec sheet. At 50MP with a Samsung sensor resolving images up to 8192 x 6144 pixels, selfies hold serious detail in good lighting. You can crop into a selfie, zoom in on facial details, or use it for portrait mode and the results are meaningfully better than the 16MP or 20MP front cameras that dominate this price range. It also shoots 4K video at up to 60fps from the front, which makes it a legitimately capable camera for content creators who film themselves regularly.

The main 108MP camera uses a Samsung sensor and the 50MP secondary rear camera uses a Sony sensor — two of the most trusted names in mobile imaging hardware. Samsung sensors are known for reliable color reproduction and good performance in varied lighting. Sony sensors are respected for natural dynamic range and detail retention. Having both manufacturers represented across the rear setup means each camera is hardware-optimised for its specific role rather than using generic chips across the board. The 50MP front camera also uses a Samsung sensor, which is why the selfie quality holds up better than most phones in this segment.

The Zero 40 5G carries a 5000mAh lithium-polymer battery. For a phone with a 144Hz AMOLED display and a 5G chip, 5000mAh is the right size

Yes —the charging package here is surprisingly complete for a mid-range device. It supports 45W wired fast charging that takes the phone from empty to full in roughly 55 to 70 minutes. Beyond that it also has 20W wireless charging, which at this price point is genuinely rare and makes a real difference for users who prefer a wireless pad on their desk or bedside table.

For the price it sits at  genuinely yes, with a couple of honest caveats. The combination of AMOLED at 144Hz, Dimensity 8200, LPDDR5X RAM, UFS 4.0 storage, a 50MP front camera, and wireless charging is a hardware package that would have cost significantly more just two years ago. Infinix has put together a phone where almost every specification punches above its weight class.
