RAM | LPDDR4X SDRAM - 4 GB | Better than 81 % of phones rated. |
---|---|---|
Internal Memory Size (Storage Capacity) | 64 GB | Better than 75 % of phones rated. |
Supported Flash Memory Cards (Expandable Memory) | Up to 256 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 A3 is LPDDR4X SDRAM - 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 A3 is equipped with 3 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 resolution of the main lens is 48 Megapixel. Higher resolution does not necessarily mean super high quality photos. Furthermore, it depends on the pixel size but also on other important factors. Pixel size is typically around 0.8-1.8 μm in better mobile phones. The higher the value, the better the quality of the resulting photo should be. In the case of main lens, the pixel size reaches 1.6 μm.
The size of the phone's sensor is also among the parameters that affect quality of the photo. In case of Xiaomi MI A3, it is 1/2". Focus mainly on the value after the slash, where the higher it is, the better photo quality will be. The aperture of main lens reaches F/1.79 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.
Second camera
The second lens of rear camera is designed as Ultra wide-angle lens. The field of view of second lens reaches 118 degree(s). The resolution reaches size of 8 Megapixel. Furthermore, the second lens is equipped with aperture of F/2.2.
Third camera
The resolution of third lens is then 2 Megapixel.
Front camera
The front camera of phone Xiaomi MI A3 has one lens. This number of lenses is standard on most smartphones nowadays. The resolution of front lens reaches 32 Megapixel. Again, it should be noted that resolution is only one of several other significant factors that affect resulting quality of a photo. The pixel size itself is 1.6 μm. The main lens is also equipped with aperture of F/2.0. As for the field of view of main lens of front camera, it reaches 79 degree(s).
BATTERY AND CHARGING Xiaomi MI A3 |
---|
Battery Capacity (Battery Size) | 4030 mAh | Better than 85 % of phones rated. |
---|---|---|
Fast Charging Technology | Qualcomm Quick Charge 3.0 | Better than 86 % of phones rated. |
The battery size of Xiaomi MI A3 is 4030 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. The fast charging function will also please many people. Owing to fast charging, phone charges up to several times faster, which you will appreciate, for example, on the go.
