Let's cut through the noise, and get to the crux of it. I have analysed and summarised, in a short and sweet 2-minute review.

Design
Beautiful, striking design - a fashion statement with a hint of premium and a paint job envisioned to impress - one of the best looking phones at this

price
The front looks equally stunning with the all-screen design with no notch or anything, thanks to the pop-up selfie camera (for the first time in this price bracket)

The fingerprint sensor is decent and there's also face unlock that works well
Slightly broader and hence makes one-hand use a bit tiresome

Display
Vibrant, punchy and large 6.53" IPS LCD screen of FullHD+ resolution - the panel has no cutouts, which makes for a more immersive experience when watching movies or playing games
The display isn't that bright and could be a problem for outdoor use

Software
The software experience on the S5 Pro is decent, it comes with XOS 6 based on Android 10 - there are a ton of useful settings such as battery saving options, themes, smart panel, social turbo, gestures, and whatnot.
The interface is heavily skinned and full of bloatware that sends spammy notifications.

Performance
Average performance with the old MediaTek Helio P35 - the phone lags when you do a lot of multitasking like opening multiple Chrome windows and then switching in between them and the games are a no go

Camera
Good triple camera for the price - 48MP primary lens, 2MP depth sensor, and a dedicated Low light sensor of 0.3MP
The daylight photos turn out pretty good with a decent amount of resolved detail, low noise, and accurate colours, the contrast is very good, as is the dynamic range
The low-light photos with the Infinix S5 Pro turn out great for this class, well exposed, with good colour saturation, and the detail is quite enough
The portrait photos are also good with proficient subject separation and convincing enough.

Battery
Good battery life with the 4000 mAh cell - will easily last a day of use with medium to heavy use


Verdict
Infinix S5 Pro is a beautiful-looking smartphone and if you're in the market for the pop-up selfie camera, nice, large display and good cameras, it makes for a decent choice
