About this deal

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. UMTS stands for Universal Mobile Telecommunications System. Based on the GSM standard, it is deemed as a 3G mobile network standard. It has been developed by the 3GPP and its major advantage is the provision of greater bandwidth and spectral efficiency, due to the W-CDMA technology. 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.

The aperture (f-stop number) indicates the size of the lens diaphragm opening, which controls the amount of light reaching the image sensor. The lower the f-stop number, the larger the diaphragm opening is, hence, the more light reaches the sensor. Usually, the f-stop number specified is the one that corresponds to the maximum possible diaphragm opening. 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. 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).

⚙️ Processor

Sign in to the Google account that is registered on your smartphone. (The Google account you used to set up your phone). 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. 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.

Autofocus, CMOS Sensor, Digital Zoom, Face Detection, Geo Tagging, HDR, LED Flash, PDAF, Panoramic Shot, Smile Detection, Stabiliser, Touch Focus, White Balance Information about the process technology used in manufacturing the chip. The value in nanometers represents half the distance between elements that make up the CPU.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. Information about the number of pixels per centimeter (ppcm) or per inch (ppi) of the display. The higher the pixel density, the more detailed and clearer is the information displayed on the screen. The SAR body rating shows the maximum level of exposure to electromagnetic radiation when the device is positioned against the body at the hip. 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. Choose the Erase device option and follow the on-screen instructions. Remember that this action will delete all user data on the internal memory of your device.

This just isn’t good enough in this day and age, especially when you’ve got budget phones that are half the price of the XA, such as the Vodafone Smart Prime 7, the Moto G 3rd Gen, and Samsung Galaxy J5, regularly exceeding at least ten hours under the same conditions. Performance

The color depth of the display is also known as bit depth. It shows the number of bits used for the color components of one pixel. Information about the maximum number of colors the screen can display. Whitwam, Ryan (23 August 2016). "Sony announces Android 7.0 upgrade list—includes the Xperia Z5, Xperia X, and more". Android Police. Illogical Robot LLC . Retrieved 23 August 2016. 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]
