The screen size reaches 5.5" inches. With a large display, phone offers a great experience for watching videos, playing games and reading. The best phones today are 6.5'' or more. They have the advantage of a large display area that allows you to see more content than with conventional display sizes. 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 A1 64 GB 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. Display´s pixel density is 403 ppi and represents another significant factor affecting image sharpness besides resolution. The higher the value, the sharper the image. Average value is currently about 350-400 ppi, which guarantees a fine and sufficiently sharp image. Finest modern phone displays reach 450 ppi and above.

PROCESSOR Xiaomi MI A1 64 GB
Processor Type (CPU) Qualcomm Snapdragon 625
Processor Number MSM8953
Clock Speed 2 GHz Better than 70 % of phones rated.
Processor Core Qty 8-core Better than 99 % of phones rated.
Graphics System (GPU) Qualcomm ADRENO 506

Xiaomi MI A1 64 GB is equipped with Qualcomm Snapdragon 625. 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. The processor frequency indicates how many instructions phone can process in 1 second. The higher the frequency, the better the performance. Standard processor frequency range today is between 1.8 GHz and 2.8 GHz. Xiaomi MI A1 64 GB reaches the frequency of 2 GHz.

The processor also includes the graphics accelerator Qualcomm ADRENO 506.

MEMORY Xiaomi MI A1 64 GB
RAM 4 GB Better than 78 % of phones rated.
Internal Memory Size (Storage Capacity) 64 GB Better than 75 % of phones rated.
Supported Flash Memory Cards (Expandable Memory) microSDHC, microSDXC - up to 128 GB

The phone´s internal memory capacity is 64 GB. The size of the internal storage determines e.g., how many photos, songs, movies, or applications you can store on your phone. For everyday use and storing photos, songs or movies, this medium-sized internal storage is ideal. The advantage is also a lower price of phones equipped with this storage capacity. Best phones today range from 256 GB to 1 TB. That size is suitable for the most demanding users who shoot a lot of high-resolution photos or videos in 4K. Nevertheless, you'll have to pay extra for these higher capacities. Luckily, most smartphone manufacturers nowadays offer models with different memory sizes to suit every user.

An additional option to increase the storage capacity of this model is to insert a memory card.

RAM memory of the Xiaomi MI A1 64 GB is 4 GB. Most powerful phones currently have an operating memory of 12 GB or more, which is especially useful for demanding users such as gaming enthusiasts. Normally, phones nowadays have 6 to 8 GB of RAM, which means that the phone can easily handle normal operation and more demanding applications. Operating memory of less than 4 GB is found in lower-end phones or older models, and they are suitable for low-end users who don't use demanding applications and have the phone more for basic use.

The rear camera of the Xiaomi MI A1 64 GB is equipped with 2 lenses, with each lens having a different role in taking pictures. Most common lens you'll see on smartphones is a wide-angle lens, telephoto lens or macro lens. A wide-angle lens is mainly used to capture landscapes and other spatially larger compositions where a wide field of view is needed. A telephoto lens is designed for photographing subjects at a distance and often has an optical zoom. A macro lens is ideal for close-ups and small objects. The main lens is designed as Wide-angle lens. The resolution of the main lens is 12 Megapixel. Higher resolution does not necessarily mean super high quality photos. Furthermore, it depends on the pixel size but also on other important factors. The aperture of main lens reaches F/2.2 value. The best phones have a lens with an aperture of up to F/1.5, where more light can pass through sensor and photos will be of a high quality even in low light conditions. However, lenses with apertures around F/1.8 to F/2.2 are the most common. The lower the number after the slash, the better the photo quality.

Digital zoom in this case offers zooming up to 10x. Of course, the higher the lens value, the more distant object can be zoomed in. Nonetheless, the disadvantage of digital zoom is that the quality and sharpness of photo deteriorates when using it. You should also pay attention to optical zoom, as it is far more important than the digital zoom. Its main advantage is that image does not lose quality or sharpness as you zoom in. Optical zoom in this case is 2x. Some users will also appreciate facial recognition feature, which allows camera to recognise the face of person in frame and automatically focus on it.

Second camera
The second lens of rear camera is designed as Telephoto lens. The resolution reaches size of 12 Megapixel. Furthermore, the second lens is equipped with aperture of F/2.6.

Front camera
The front camera of phone Xiaomi MI A1 64 GB has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of front lens reaches 5 Megapixel. Again, it should be noted that resolution is only one of several other significant factors that affect resulting quality of a photo. The main lens is also equipped with aperture of F/2.0.

A nice bonus here is the facial recognition function.

BATTERY AND CHARGING Xiaomi MI A1 64 GB
Battery Capacity (Battery Size) 3080 mAh Better than 71 % of phones rated.
Battery Technology Lithium Ion

The battery size of Xiaomi MI A1 64 GB is 3080 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.
