Sony Xperia XA1 SIM-Free Smartphone - Black

Product Information

The Xperia XA1’s interface is one most people won’t have big problems with, then. It’s fairly responsive too; the only performance complaint I have is that in some apps, tapping in text sometimes seems to lag behind your fingers. Exmor R for mobile™ for mobile image sensor, Low-light photo: up to ISO 3200, 23mm wide-angle lens f2.0, SteadyShot™, Low-light video: ISO 3200 A CPU core is the processor unit, which executes software instructions. Presently, besides single-core processors, there are dual-core, quad-core, hexa-core and so on multi-core processors. They increase the performance of the device allowing the execution of multiple instructions in parallel. Tip: If you can’t turn off your Xperia device before performing a software repair, force it to shut down. To shut down, press and hold down the power key and the volume up key simultaneously until the device emits three vibrations.

Whites have a slightly blue tinge to them and viewing angles are fairly narrow; but, again, colour images are well represented and there are no standout problems. One of the main characteristics of the display is its type/technology, on which depends its performance.CPU is the Central Processing Unit or the processor of a mobile device. Its main function is to interpret and execute instructions contained in software applications. Focal length is the distance in millimeters from the focal point of the image sensor to the optical center of the lens. The 35 mm equivalent indicates the focal length at which a full-frame camera will achieve an angle of view that's the same as the one of the camera of the mobile device. It is measured by multiplying the native focal length of the camera by the crop factor of the sensor. The crop factor itself can be determined as the ratio between the diagonal distances of the image sensor in the 35 mm camera and a given sensor. Games run very well on this phone – even high-end ones. It comes down to a combo of a reasonably powerful processor and a really-not-that-demanding screen. The Helio P20 is designed to handle phones with up to 1080p screens, and this one is only 720p.

The compromise comes in what this little guy is made of. From arm’s length it looks like a full metal phone, but the Xperia XA1 is mostly made of plastic. Only the sides are actually made of the good stuff. However, because your fingertips tend to rest on the aluminium bits, you still get a hint of that hard, dense feel of metal. The SAR head rating shows the highest level of exposure to electromagnetic radiation measured when the device is held next to the ear in a talk position. In Europe, the SAR limit for hand-held mobile devices is set to 2 W/kg per 10 g of tissue. This standard is specified by the CENELEC, complies with the IEC standards and follows the ICNIRP Guidelines 1998. The instruction set architecture (ISA) is a set of commands used by the software to manage the CPU's work. Information about the set of instructions the processor can execute.

Youngsters probably won't appreciate that holding the phone in landscape means this key is where the shutter button would be on an actual camera, but we know. The one last stab (I promise) is that image sharpness takes a dive as you reach the edge of the frame. It all goes a but mushy, like a painter who ran out of steam after painting the figure in the middle of the frame. The lens clearly isn’t that great, although the same has applied to previous Sony top dogs. Color is respectably rich and vivid. It loses out to the XZ Premium, which can deliver incredible saturation for an LCD phone, but the Xperia XA1 actually strikes a good balance between punch and a natural look.

Information about the height, i.e. the vertical side of the device when it is used in its standard orientation.The software update function of Xperia Companion cannot be used with Xperia smartphones released in May 2022 and after. stand-by time is the longest time a battery charge will last, if the device is not used but is constantly connected to the 3G mobile network. There are themes too, and you can even choose the screen transition animation. In other words, it’s a typical custom Android UI. The rear cameras of mobile devices use mainly a LED flash. It may arrive in a single, dual- or multi-light setup and in different arrangements. For Xperia smartphones released in May 2022 and after, you will need to configure the data transfer setting in your Xperia smartphone when you connect it to your computer. After connecting it to your computer with a USB cable, find and tap [Settings] > [Device connection] > [USB], and then select [File Transfer] for [Use USB for].

Information about the number of pixels on the horizontal and vertical dimensions of the photos taken by the front camera, indicated in megapixels as well. The Xperia XA1 Plus has been pitched as 'super mid-tier', and we think that's about right. It offers middling processing, storage and memory, but amps up the battery and screen size to offer something like the phone equivalent of 'Premium Economy.' A little more this, a little more that, but still a (reasonably) little price tag.Information about the width, i.e. the horizontal side of the device when it is used in its standard orientation. Estimated volume of the device, calculated from the dimensions provided by the manufacturer. Applies for devices in the form of a rectangular parallelepiped. For day-to-day performance, it’s fine. I could read it in direct sunlight at maximum brightness, although at night I found even minimum brightness a little too bright for my sensitive, sleepy eyes. The battery type is determined by its structure and more specifically, by the chemicals used in it. There are different battery types and some of the most commonly used in mobile devices are the lithium-ion (Li-Ion) and the lithium-ion polymer battery (Li-Polymer).
