Apple iPhone 8, 64GB, Space Grey (Renewed)

Product Information

Networks A mobile (cellular) network is a radio system, which allows a large number of mobile devices to communicate with each other. GSM 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. AAC-LC, HE-AAC, HE-AAC v2, Protected AAC, MP3, Linear PCM, Apple Lossless, FLAC, Dolby Digital (AC-3), Dolby Digital Plus (E-AC-3), Audible (Formats 2, 3, 4, Audible Enhanced Audio, AAX, and AAX+)

Information about the capacity of the built-in storage of the device. Sometimes one and the same model may is offered in variants with different internal storage capacity. 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.Testing conducted by Apple in August 2017 using preproduction iPhone 8 and iPhone 8 Plus units and software and accessory Apple USB-C Power Adapters (18W Model A1720, 29W Model A1540, 30W Model A1882, 61W Model A1718, 87W Model A1719). Fast-charge testing conducted with drained iPhone units. Charge time varies with environmental factors; actual results will vary. Audio formats supported: AAC-LC, HE-AAC, HE-AAC v2, Protected AAC, MP3, Linear PCM, Apple Lossless, FLAC, Dolby Digital (AC-3), Dolby Digital Plus (E-AC-3), and Audible (formats 2, 3, 4, Audible Enhanced Audio, AAX, and AAX+) Information about the electric current (amperes) and voltage (volts) the charger outputs. The higher power output allows faster charging.

Display The display of a mobile device is characterized by its technology, resolution, pixel density, diagonal length, color depth, etc. Type/technology The loudspeaker is a device, which reproduces various sounds such as ring tones, alarms, music, voice calls, etc. Information about the type of speakers the device uses. Pixels are usually measured in microns (μm). Larger ones are capable of recording more light, hence, will offer better low light shooting and wider dynamic range compared to the smaller pixels. On the other hand, smaller pixels allow for increasing the resolution while preserving the same sensor size.There will be light signs of wear on the body but invisible at a distance of 20 inches (arms length). The screen however will have no scratches. Durability scores are above average, and chances of encountering any technical issues are small. Excellent One of the main characteristics of the cameras is their image resolution. It states the number of pixels on the horizontal and vertical dimensions of the image, which can also be shown in megapixels that indicate the approximate number of pixels in millions.

Sensors Different sensors measure different physical quantities and convert them into signals recognizable by the mobile device. Sensors

CDMA2000 is a family of 3G standards for mobile networks based on CDMA and providing high-quality voice and broadband data services over wireless networks. Its advantages include stronger signal, fewer drop-offs and breakups, analog capabilities, very high spectral capacity, etc. 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). 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. 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.
