The Infinix Note 8 has only one useful camera which is the 64MP main camera. The rest are duds. The Xiaomi Redmi 9 has what seems to be on paper the inferior main camera, but the main shooter is made by Omnivision. The 64MP on the Infinix is going to be binned back to 16MP. The pixels on the Redmi 9’s main shooter are two times bigger than those on the Infinix and would have better and brighter pictures. Where the Infinix shines is in terms of resolution. The ultrawide and the macro on the Redmi 9 are very decent while those on the Infinix are plain useless. MIUI’s photo software algorithm is also better than that of the XoS.


In the video department however, the Infinix Note 8 shoots videos of 1440p (@30fps) which are of a higher resolution than those shot by the Redmi 9. This is because it’s main camera has a higher resolution. The Redmi 9 shoots videos of 1080p (@30fps). The front facing selfies of both phones shoot videos of 1080p (@30fps).

In truth both phones are closely matched, the performance difference the both of them is very negligible. The Infinix has a much better main camera but the supporting camera sensors aren’t of much use other than aesthetics. The display is where the Redmi 9 stands heads and shoulders above the Infinix Note 8. FHD+ and 395ppi are miles ahead of HD+ and 258ppi.

Infinix Note 8 has a gyroscope which the Redmi 9 lacks. The gyroscope is very important for gaming and virtual reality apps. The Redmi 9 has NFC while the Infinix Note 8 does not. For the price, the Redmi 9 is my go-to-device, if you can ignore the absence of a gyroscope. If you can’t, then you would have to spend more and go for the Infinix Note 8.
