How do we rate a Device?

Rating a smartphone is a tedious process and a lot of parameters have to be considered before judging the overall performance of the device such as display, camera, processor, RAM, storage, battery, and the pricing.

So, here are how these specs will affect the real-life usage of a device and why how we meticulously consider each of these points to rate a smartphone.


Cameras have evolved a lot over the last few years and multi-camera setup is a new norm. We consider various parameters like MP count, aperture size, pixel size, image stabilization to rate a camera system of a smartphone out of 5. Any device that scores more than 3.5 can take good photos and videos and if a phone scores over 4, then it will be one of the best camera smartphones in the market.


Though battery seems like an underrated feature and we look at the battery capacity, fast charging supporting technology, and even the wireless charging capability is also taken into consideration to rate smartphone's battery capability.


The display is the face of a smartphone. And there are a lot of parameters like the panel technology (IPS LCD, OLED, TFT) and other parameters also taken into consideration like the resolution, pixel density, and refresh rate.

Value for Money

A smartphone could have great specs, but if it is not priced well then you might not get the best value-for-money. So, we compare a smartphone with the contemporaries to rate the value-for-money of a device out of 5.


This aspect is decided on various sub specifics, such as availability of microSD card slot, the amount of RAM the device offers, processor capability, and the network support. This parameter has more weightage when compared to other departments.
