talk time is the time period a battery charge will last, if one is constantly talking on the phone in a 2G cellular network. RAM (Random-Access Memory) is used by the operating system and all installed applications. Data in the RAM is lost after the device is turned off or restarted.
One of the main characteristics of the display is its type/technology, on which depends its performance. In photography, the Field of view (FoV) depends not only on the focal length of the lens but also on the sensor size. It is derived from the lens's angle of view and the sensor's crop factor. The lens's angle of view is a measure of the angle between the two farthest separated points within the frame measured diagonally. Simply put, this is how much of a scene in front of the camera will be captured by the camera's sensor.The device features a 5.0-inch 720p screen and a 64-bit 2.0GHz octa-core Mediatek MT6755 (Helio P10) system-on-chip with 2GB of RAM. The device also has 16GB internal storage with microSD card expansion up to 200GB and includes non-removable 2300 mAh battery. [2] UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1900 (Band II), 2100 (Band I) MHz GSM GPRS/EDGE 850, 900, 1800, 1900MHz LTE (Bands 1, 3, 5, 7, 8, 28, 38, 39, 40, 41M)
The Xperia XA is preinstalled with Android 6.0.1 Marshmallow with Sony's custom interface and software. [4] On August 23, 2016, Sony announced that the Xperia XA would receive an upgrade to Android 7.0 Nougat. [5] On June 16, 2017, it was reported that Android 7.0 Nougat was rolling out to the Xperia XA. [6] Variants [ edit ] How to use the Software repair feature on Xperia Companion to reset my Xperia phone What do I need to reset my phone this way? 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.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. System on Chip (SoC) A system on a chip (SoC) includes into a single chip some of the main hardware components of the mobile device. SoC Similar to the CPU, the GPU consists of processing units called cores. They handle the computation of graphics in various applications. Turn off your Xperia smartphone and remove the SD card to avoid deleting user data from the SD card. This is a real shame, as Sony’s displays have consistently been one of its key strengths. Sadly, the XA also lags behind on brightness, topping out at 407.43cd/m2. This is by no means terrible, and still just about good enough to see the screen clearly outdoors in direct sunlight, but when the Xperia X, M5 and even 2014’s M4 Aqua all broke 500cd/m2, the XA once again feels quite dull by comparison. Contrast was reasonably good and I measured a ratio of 1,119:1, so at least you get a decent gradient between lights and darks.

The display resolution shows the number of pixels on the horizontal and vertical side of the screen. The higher the resolution is, the greater the detail of the displayed content. The software update function of Xperia Companion cannot be used with Xperia smartphones released in May 2022 and after.

The highest SAR value of mobile devices allowed in the US is set to 1.6 W/kg per 1 g of tissue. It is specified by the FCC and the CTIA follows whether the mobile devices comply with this standard.
