The screen size reaches 5" inches. Smaller phone displays are not necessarily a disadvantage. They are easier to use with one hand. However, displays of these sizes don't provide the same experience when watching videos or playing games, so they're better suited for less demanding users. It means, if you're a basic user and you don't expect to use your phone for activities like watching videos or playing games on regular basis, this size is perfectly adequate.
Display Resolution of Xiaomi Redmi 3S is 1280 x 720 pixels. A higher display resolution is a prerequisite for a sharper image. The standard for mid-range phones today is a Full HD resolution of 1920 × 1080 px. Cheaper phones, which usually have a smaller diagonal, have an HD resolution of 1280 × 720 px. Smaller resolutions can only be found in older models. Best phones, on the other hand, have a 4K resolution of 3840 x 2160 px.

Graphics System (GPU) | Qualcomm ADRENO 505 |
The processor type of the Xiaomi Redmi 3S is Qualcomm Snapdragon 430. The number of processor cores is 8. It is a number of cores that plays an important role in evaluating the performance of phone as it is responsible for computing operations. Smartphones already commonly have a core count of around 4 to 8. Multi-core processors can perform better and reduce the processing time of a request to a minimum, which is reflected in the responsiveness of the phone, e.g. in the speed of opening applications. Xiaomi Redmi 3S is provided with processor´s frequency of 1.4 GHz. Normally today you will find this value between 1.8 and 2.8 GHz, and the higher the number, the faster the response of the phone. The processor frequency will thus be one of the important parameters if you are looking for a phone capable of managing several requests at once without major problems.
The processor also includes the graphics accelerator Qualcomm ADRENO 505.
MEMORY Xiaomi Redmi 3S |

RAM | 2 GB | Better than 55 % of phones rated. |
---|---|---|
Internal Memory Size (Storage Capacity) | 16 GB | Worse than 53 % of phones rated. |
Supported Flash Memory Cards (Expandable Memory) | microSDHC, microSDXC - up to 128 GB |
The phone is provided with an internal memory of 16 GB. Internal storage capacity is often a key parameter, as it determines how many files, photos, apps and more your phone can store. This memory capacity is ideal for those who have a few basic apps and a few dozen photos on their phone. If you don't expect to use your phone to play games or need to store high-resolution photos, this size should be sufficient. There is almost no probability you're likely to see this low capacity on new smartphones. The standard memory today is around 64 and 128 GB. The best phones have internal memory of 256 GB or more. Fortunately, manufacturers nowadays think of all users and therefore offer phone models with different memory sizes so that everyone can choose what suits them.
In addition, if you need more memory, this model offers the option of inserting a memory card to increase the storage size.
Operating memory significantly affects the performance of the entire phone. Xiaomi Redmi 3S has an operating memory of 2 GB. Phones with less than 4 GB of RAM are better suited for undemanding users who use phone more for basic needs and some essential applications only. But if you are a heavy user, reach for at least 6 to 8 GB of RAM, which is the standard today, or 12 GB for the really demanding ones.

The rear cameras of modern phones nowadays are usually equipped with two, three and sometimes even five rear camera lenses. A high resolution lens alone does not necessarily mean high quality photos. The main lens in this has a resolution of 13 Megapixel. However, if you are looking for perfect photos, in addition to resolution, don't forget to focus on at other parameters such as lens aperture or pixel size. Luminance is one of the main factors determining the quality of a photograph. Commonly today, this value ranges between F/1.8 and F/2.2. However, best photomobiles have an aperture of up to F/1.2. Value indicates how much light passes through the sensor and the lower it is, the better the quality of the photos. Main lens here is equipped with F/2.0.

The battery size of Xiaomi Redmi 3S is 4100 mAh. Nevertheless, battery capacity is not the only factor that affects the phone's battery life. For example - the size of the display, the performance of the processor, the use of data functions and, of course, the intensity of use of phone in general all have a significant impact on battery life. Standard for most smartphones today is a battery capacity of around 4500 to 5000 mAH. Phones with this battery size usually guarantee a phone life of at least 1 day. Older or cheaper smartphone models can then reach battery capacities typically around 2500 mAH and below. With this capacity, you may find that if you use your phone heavily, you may need to recharge your phone during the day.
