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. iPhone 8 and iPhone 8 Plus are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP67 under IEC standard 60529 (maximum depth of 1 meter up to 30 minutes). Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty. The iPhone 8 set a new bar in terms of cost for Apple's most mainstream handset, as it upped its launch price tag once again.

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.English, Chinese (Simplified, Traditional), Danish, Dutch, French, German, Hebrew, Hindi, Italian, Japanese, Korean, Norwegian, Portuguese, Russian, Spanish, Swedish, Thai, Turkish Information about the sensor type of the camera. Some of the most widely used types of image sensors on mobile devices are CMOS, BSI, ISOCELL, etc. Specific Absorption Rate (SAR) The SAR rating shows the amount of electromagnetic radiation absorbed by the human body when using a mobile device, expressed in W/kg. Head SAR (EU)

Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology Information about the manufacturer and model of the image sensor used by this camera of the device. 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. SoCOne of the big upgrades Apple has given its new iPhone, and the focus of the design, is the glass rear – it’s an upgrade over the aluminium body used since the iPhone 5, and its inclusion means a brand-new feature in the shape of wireless charging.

FaceTime calling requires a FaceTime-enabled device for the caller and recipient and a Wi-Fi connection. Availability over a cellular network depends on carrier policies; data charges may apply. We have a transparent grading system that considers both the physical appearance and technical condition of any given device. Do note that all devices sold are guaranteed to be 100% functional and technical condition refers to the durability you can expect from a product given its refurbisher's operations and historical quality data. We have three-well defined conditions based on your needs: Fair 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. It all works, the design is functional, and it’s not a bad-looking handset – but glance at that price tag and it’s hard not to feel a little short-changed on initial inspection. 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.One of the main characteristics of the display is its type/technology, on which depends its performance. Information about additional software and hardware features of the rear camera which improve its overall performance. The capacity of a battery shows the maximum charge, which it can store, measured in mili-Ampere hours.

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). Apple takes a complete product life cycle approach to determining our environmental impact.

It’s not like Apple has missed this trend – the bezeless iPhone X is testament to the fact that it hasn’t – but it means the iPhone 8 and iPhone 8 Plus look ever-more dated against the competition, which now includes a rival in their own camp.Touch ID Fingerprint Sensor Built into the Home Button, Barometer, Three-axis Gyro, Accelerometer, Proximity Sensor, Ambient Light Sensor
