The iPhone 5s is not a radical departure in design for Apple, save for one very important feature. This A7 processor debuts on the iPhone 5s as the first 64-bit mobile chipset in use on a commercial device, utilized by the latest flat and minimalistic iOS 7 that has been rewritten to take advantage of the 64-bit system.
The iSight camera stayed 8 MP, but is much improved, with larger pixels, wider aperture, and the ability to shoot slow motion videos, not to mention the dual two-tone LED flash on the back that strives for natural skin color representation.
Pixel density - The pixel density of a display represents the number of pixels over an area of one inch. Technology - There are two main screen technologies currently used in phones and tablets: LCD and AMOLED.
Newer LCD variations like IPS-LCD and Super-LCD allow for very accurate color reproduction and very wide viewing angles, where no significant image quality loss is observed. Aperture size - The aperture of a camera is the opening through which light travels before it reaches the camera sensor. System chip - Most modern handsets use an advanced chip that includes many of the devicea€™s hardware modules like the processor, Wi-Fi, Bluetooth and sometimes even the wireless radio. Processor - The processor is the main computing component of a phone and is a major factor when it comes to the overall speed of the device.


System memory - System memory, or RAM memory is the type of memory that the device uses to temporarily store data from the OS or currently-running apps. GPS - This is one of the most widespread global positioning technologies, developed and maintained by the U.S.
A-GPS - A-GPS stands for Assisted GPS and is the industry standard for positioning and navigation. FCC approval - The Federal Communications Commission (FCC) is an independent United States government agency, directly responsible to Congress. FCC measured SAR - Working closely with federal health and safety agencies, such as the Food and Drug Administration (FDA), the FCC has adopted limits for safe exposure to radiofrequency (RF) energy. Despite our efforts to provide full and correct Apple iPhone 5s specifications, there is always a possibility of making a mistake. If you are interested in using our specs commercially, check out our Phone specs database licensing page. The former usually features a light source and liquid crystals, while the latter is based on organic light-emitting diodes. The FCC was established by the Communications Act of 1934 and is charged with regulating interstate and international communications by radio, television, wire, satellite and cable.


These limits are given in terms of a unit referred to as the Specific Absorption Rate (SAR), which is a measure of the amount of radio frequency energy absorbed by the body when using a mobile phone.
A technique of multiplexing, also called spread spectrum, in which analog signals are converted into digital form for transmission. We have in mind the home button that has been on iPhones from day one, is now turned into a fingerprint scanner dubbed Touch ID. The FCC requires cell phone manufacturers to ensure that their phones comply with these objective limits for safe exposure. For each communication channel, the signals are encoded in a sequence known to the transmitter and the receiver for that channel. It lets you unlock the phone and authorize purchases, safely storing your fingerprints in the A7 processor itself, out of the reach for anyone but a few default iOS 7 apps.
The foremost application is digital cellular phone technology from QUALCOMM that operates in the 800MHz band and 1.9GHz PCS band.
