Sony XPERIA XA2 Ultra Specifications, Tests and Review

Design of Sony XPERIA XA2 Ultra has dimensions of 163 mm × 80 mm × 9.5 mm and weight of 221 g.

The screen size reaches 6" 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 Sony XPERIA XA2 Ultra 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. If you want a perfect picture, focus on pixel density in addition to resolution. This number indicates how sharp the image will be. Best phones today have a display fineness of 450 ppi or higher, but the today´s average is around 350-400 ppi. That should be enough for you to enjoy a fine and sharp image. This model has a pixel density of 367 ppi.

The processor type of the Sony XPERIA XA2 Ultra is Qualcomm Snapdragon 630. 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 also includes the graphics accelerator Qualcomm ADRENO 508.

The phone is provided with an internal memory of 32 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. Sony XPERIA XA2 Ultra has an operating memory of LPDDR4X SDRAM - 4 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 camera of the Sony XPERIA XA2 Ultra 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. A high resolution lens alone does not necessarily mean high quality photos. The main lens in this has a resolution of 23 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.

The size of the camera's sensor also influences the final quality of the photos. Sony XPERIA XA2 Ultra´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. 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. 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 5x.

Front camera
The front camera of Sony XPERIA XA2 Ultra is equipped with 2 lenses, with each lens having a different function when taking pictures. The main front lens is designed as a Wide-angle lens. The resolution of main lens reaches 16 Megapixel. Again, it should be noted that resolution is not the only factor affecting the quality of the front camera photo. The aperture of main lens is F/2.0.

Second front camera
You won't see a second front lens on most smartphones yet. Having more than one front lens in Sony XPERIA XA2 Ultra is thus rather exceptional in world of phones. The resolution of second front lens reaches 8 Megapixel. The lens aperture is designed to F/2.4.

The battery size of Sony XPERIA XA2 Ultra is 3580 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.

Standby time is 707 hours. The value indicates how long your phone will last on a single charge when you are not actively using it. The battery life when making calls is, like standby time, a figure that tells us how long the phone will last on a single charge when making continuous calls. For the Sony XPERIA XA2 Ultra it is 2460 minutes. 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.

Sony XPERIA XA2 Ultra supports 4G. 4G connectivity is still common today, although the latest phones already have 5G connectivity. 3G connectivity is now more of a thing of past and can only be found on older models. The phone's operating system is Android 8.0 Oreo.

The NFC function will please all fans of contactless mobile payments. In addition, you can also use function in the context of connectivity, for example, to unlock doors or load menus in restaurants. Bluetooth 5.0 makes it easy to connect your phone to other wireless devices such as headphones, speakers, TV or tablet and more.
