The Infinix ZERO 40 5G features a unique design. Its polycarbonate back has a textured finish, providing a comfortable grip. However, the poor weight distribution makes the large 5,000mAh battery noticeable during use.
The iQOO Z9s Pro 5G comes with a flagship design and is available in Flamboyant Orange and Luxe Marble shades. We got the Luxe Marble variant, which has a wavy pattern similar to marble tiles, offering a premium finish. It is also slim with excellent weight distribution despite housing a slightly large battery and boasts elegant curves, adding to the premium touch.
To conclude, we prefer the IQOO Z9s Pro 5G as it is thinner and lighter with excellent weight distribution and an advanced IP64 rating.

The Infinix ZERO 40 5G offers vibrant colours and supports Widevine L1 certification out of the box which can stream 1080p content. The screen is also bright enough outdoors and only requires less than 50% brightness indoors. The dual stereo speakers offer loud music but lacks an oomph factor.
The iQOO Z9s Pro 5G also offers vibrant colours and supports Widevine L1 certification with HDR playback. It holds up well against sunlight outdoors and suffices well indoors. The dual stereo speaker setup offers crisp and clear voices up to 75% volume and produces distortion when using ultra volume boost.
Here, we prefer the iQOO Z9s Pro 5G over the Infinix ZERO 40 5G as it offers a better media consumption experience.
Infinix ZERO 40 5G vs iQOO Z9s Pro 5G: Cameras
| Infinix ZERO 40 5G | iQOO Z9s Pro 5G | |
| Primary Camera | 108MP Samsung HM6 primary camera with OIS and f/1.75 aperture | 50MP Sony IMX882 primary camera with OIS and f/1.8 aperture |
| Ultrawide Camera | 50MP ultrawide camera with f/2.2 aperture and a field of view of 120˚ | 8MP ultrawide camera with f/2.2 aperture and field of view of 112˚ |
| Tertiary Camera | 2MP depth camera with f/2.4 aperture | NIL |
| Front Camera | 50MP selfie camera with f/2.5 aperture | 16MP snapper with f/2.45 aperture |
The Infinix ZERO 40 5G delivers excellent photos with accurate colours and HDR processing. It captures satisfactory portrait shots and impressive details in lowlights. The ultrawide camera also produces decent images with extra contrast. However, it lacks details and has a pinkish tint when shot against sunlight, similar to a primary camera.
The ultrawide lens shows occasional lens flare, giving it an artistic effect. Both cameras also slow down in low light, resulting in blurry photos. The selfies also come out with excellent details in well-lit situations. It slightly smooths the face in low-light conditions.
On the contrary, the iQOO Z9s Pro 5G captures crisp, sharp, and vivid images in daylight. The ultrawide camera also captures wide images without any lack of detail, despite its lower resolution. The iQOO Z9s Pro 5G excels in portraits, and the outputs are praiseworthy, which is way better than the competitor.
Low-light images show grain and are not that great. iQOO has enabled a filter mode for selfies by default, which produces unnatural images. However, turning off the filter mode will result in natural-looking images with accurate skin tones.
To sum up, the Infinix ZERO 40 5G is a better pick with respect to overall performance. The iQOO Z9s Pro 5G has an edge in portraits, selfies, and ultrawide shots.
