Xiaomi MI 5s Specifications, Tests and Review

The Xiaomi MI 5s has dimensions 145.6 mm × 70.3 mm × 8.25 mm. Its weight is 145 g.

The screen size reaches 5.15" inches. Phones with smaller displays have the advantage of being easier to use with one hand. However, compared to phones with large screens, they provide a lower user experience. Nevertheless, if you don't plan to watch movies or play games on your phone regularly and just expect basic functionality, this size should be good enough for you. The disadvantage of LCD displays is the relatively lower color contrast displayed, as the technology cannot display absolute black well. Also due to the higher power consumption, LCD displays are no longer as common in phones. Even so, some manufacturers still equip their phones with LCD technology. However, modern smartphones are already using OLED technology. The advantage of LCD phones is that they tend to be cheaper to build than OLED technology.

Display Resolution of Xiaomi MI 5s is 1920 x 1080 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. Another important factor having impact on the final image is display´s pixel density. In case of this model, the value reaches 428 ppi. With pixel density, the higher the value, the sharper the image will be. On average today, the image fineness value is around 350-400 ppi. This will guarantee a sufficiently fine and sharp image for normal use. However, the best phones on the market today are equipped with pixel density of 450 ppi or higher.

Xiaomi MI 5s is supplied with Qualcomm Snapdragon 821. Another important parameter is the processor frequency, which indicates how many instructions the phone can process in one second. Similar to refresh rate, the higher the number, the faster the phone responds. Processor frequency of phone Xiaomi MI 5s is 2.15 GHz. As standard today, you'll find this value between 1.8 GHz and 2.8 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 530.

One of the most important parameters for user´s decision is often internal memory capacity. The larger it is, the more apps, photos, movies and other files your phone can store. This phone has 64 GB storage. It is currently the most common storage size among today´s smartphones. The capacity is perfectly adequate for the average user. It will allow you to store thousands of photos, high-resolution videos, dozens of apps and several games on your phone. But if you're one of those really demanding users and you use your phone to shoot 4K videos etc., then you should rather pay extra to have a larger storage of 256 GB or more. Nowadays, you can usually find one phone model on the market with several different memory sizes. This allows each user to choose what suits them best.

Size of the RAM memory tells us how powerful the phone is. Xiaomi MI 5s is equipped with LPDDR4 SDRAM - 3 GB. Commonly today you will find phones with 6 to 8 GB of RAM. This means that the phone can easily handle normal operation and more demanding applications or games. Higher RAM of 12 GB can be found in best phones on market and are ideal especially for avid gamers. On the other hand, operating memory below 4 GB is more of an issue with lower-end phones and older models. However, even they will find their fans among less demanding users, who don´t want to spend much on buying new phone.

The rear camera of the Xiaomi MI 5s has only one lens. Single lens is more typical for older phones or lower-end phones with lower quality cameras. The rear cameras of modern phones nowadays are usually equipped with two, three and sometimes even five rear camera lenses. The main lens is designed as Wide-angle lens. The resolution of main lens is 12 Megapixel. Nonetheless, resolution alone does not necessarily mean a good photo. Therefore, you should look at other parameters such as lens aperture or pixel size.

The size of the camera's sensor also influences the final quality of the photos. Xiaomi MI 5s´s main lens is designed with a sensor size of 1/2.3". The higher the value after the slash, the higher the resulting photo quality. Another important factor is the aperture, which in this case is F/2.0 and determines how much light passes through the sensor. Best phones have an aperture of up to F/1.5. But the most common lenses today are F/1.8 to F/2.2. In this case, the lower the number after the slash, the higher the photo quality. Many people will also benefit from the facial recognition feature. In translation it means the camera can recognise face of person in the frame and automatically focus on it.

Front camera
The front camera of phone Xiaomi MI 5s has one lens. This number of lenses is standard on most smartphones nowadays. The main front lens is designed as a Wide-angle lens. The lens is equipped with 4 Megapixel. However, do not forget there are other factors than resolution having impact on the final quality of front camera photos. The main front lens also achieves F/2.0.

A nice bonus here is the facial recognition function.

The battery size of Xiaomi MI 5s is 3200 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. You'll also enjoy the fast charging function, which allows for faster power flow and thus up to several times faster charging of the phone.

Standard 4G connectivity is currently being replaced by 5G, but is still the preserve of the latest phones. Xiaomi MI 5s supports 4G. 3G connectivity is now only found in the oldest phones.

Contactless payments are not a problem with this phone, thanks to NFC function. It can also be used, for example, to unlock doors or load menus in a restaurant using an NFC tag. Bluetooth 4.2 must not be missing from the basic package. It makes it easy to connect wireless headphones to your phone, connect your phone to your TV, tablet, speaker and more.
