IPhone 5s
The iPhone 5s is a smartphone that was developed and marketed by Apple. It is the seventh generation of the iPhone, succeeding the iPhone 5, and was unveiled in September 2013 alongside the iPhone 5c.
The iPhone 5s has almost the same external design as well as the same 4-inch screen as its predecessor, the iPhone 5. The 5s received a new white/gold color scheme in addition to white/silver and space gray/black. The 5s features upgrades mostly in the form of internal hardware; it introduced the Apple A7 64-bit dual-core system-on-chip, the first 64-bit processor to be used on a smartphone, accompanied by the M7 "motion co-processor". A redesigned home button with Touch ID – a fingerprint recognition system which can be used to unlock the phone and authenticate App Store and iTunes Store purchases – was also introduced. The camera was updated with a larger aperture and a dual-LED flash optimized for different color temperatures. EarPods, which were introduced the year prior and had been shipping with the iPhone 5, were included in the box.
The iPhone 5s originally shipped with iOS 7, which introduced a revamped visual appearance among other new features. Designed by Jony Ive, iOS 7 departed from skeuomorphic elements used in previous versions of iOS in favor of a flat, colorful design. Among new software features introduced to the iPhone 5s were AirDrop, an ad-hoc Wi-Fi sharing platform; Control Center, a control panel containing a number of commonly used functions; and iTunes Radio, an internet radio service. The 5s is the first iPhone to be supported through six major versions of iOS, from iOS 7 to iOS 12, and the second iOS device to support five major updates – the first being the iPad 2 which supported iOS versions 4 to 9.
Reception towards the device was positive, with some outlets considering it to be the best smartphone available on the market due to its upgraded hardware, Touch ID, and other changes introduced by iOS 7. Some criticized the iPhone 5s for keeping the design and small display of the iPhone 5, and others expressed security concerns about the Touch ID system. Nine million units of the iPhone 5s and iPhone 5c were sold on the weekend of their release, breaking Apple's sales record for iPhones. The iPhone 5s was the best selling phone on all major U.S. carriers in September 2013.
The iPhone 5s was succeeded as Apple's flagship smartphone by the larger iPhone 6 in September 2014. On March 21, 2016, the iPhone 5s was discontinued following the release of the iPhone SE, which incorporated internal hardware similar to the iPhone 6s while retaining the smaller form factor and design of the 5s.
History
Before its official unveiling, media speculation primarily centered on reports that the next iPhone would include a fingerprint scanner; including Apple's 2013 acquisition of AuthenTec, a developer of mobile security products, references to a fingerprint sensor on the home button in the beta release of iOS 7 and leaked packaging for an iPhone 5s showing that the traditional home button now had a metallic "ring" around it. Similar ring-based imagery was seen on the official invitation to Apple's iPhone press event in September 2013, where the new device was unveiled. Shortly before its official unveiling, The Wall Street Journal also reported the rumor.Apple announced the iPhone 5c and the iPhone 5s during a media event at its Cupertino headquarters on September 10, 2013. While the iPhone 5c became available for preorder on September 13, 2013, the iPhone 5s was not available for preorder. Both devices were released on September 20, 2013. While most of the promotion focused on Touch ID, the 64-bit Apple A7 processor was also a highlight during the event.
Schiller then showed demos of Infinity Blade III to demonstrate the A7's processing power and the device's camera using untouched photographs. Apple also announced during the keynote that iOS 7 would be available on September 18, 2013.
On September 20, 2013, the iPhone 5s was released in the United States, United Kingdom, Canada, China, France, Germany, Australia, Japan, Hong Kong, and Singapore. It was released in 25 additional countries on October 25, 2013, and in 12 countries on November 1, 2013. Indonesia was the last country to receive the iPhone 5s, on January 26, 2014. The iPhone 5s was succeeded as Apple's flagship smartphone by the iPhone 6 and iPhone 6 Plus on September 19, 2014, but the older model remained available for purchase at a reduced price, while the 64 GB version was discontinued. The gold edition of the iPhone 5s was discontinued on September 9, 2015, when Apple revealed the iPhone 6s and iPhone 6s Plus
The iPhone 5s was discontinued on March 21, 2016, and succeeded by the first-generation iPhone SE, which continues the same form factor but features vastly upgraded internals similar to the flagship iPhone 6s. This was a break with Apple's product positioning trend, starting with iPhone 4s released in October 2011, which gave each newly released model one year as the flagship phone, then moving it to midrange for its second year of production, with the third and final year as the entry-level offering before discontinuation. While the iPhone 5s was expected to continue on sale until September 2016, replacing it and its A7 processor early meant that Apple "just reduced its long-term chip support window by a year" for iOS. In addition, a new iPhone launch was meant to stimulate demand, as sales of iPhone 6s and 6s Plus had not met expectations since their September 2015 release and the iPhone family was expected to suffer its first-ever negative growth quarter in 2016.
Specifications
Design
The iPhone 5s maintained a similar design to the iPhone 5, with a LCD multi-touch Retina display and a screen resolution of 640×1136 at 326 ppi. Its home button has been updated with a new flat design using a laser-cut sapphire cover surrounded by a metallic ring; the button is no longer concave, nor does it contain the familiar squircle icon seen on previous models. The phone itself is thick and weighs. The phone uses an aluminum composite frame. The device is available in three color finishes; "space gray", white with silver trim, and white with gold trim. The iPhone 5s was the first iPhone to be available in a gold color; this decision was influenced by the fact that gold is seen as a popular sign of a luxury product among Chinese customers.Hardware
The iPhone 5s is powered by the Apple A7 system-on-chip, the first 64-bit processor ever used on a smartphone. The device's operating system and pre-loaded software were optimized to run in 64-bit mode, promising increased performance, although third-party app developers would need to optimize their apps to take advantage of these enhanced capabilities. The A7 processor was designed by Apple and manufactured by Samsung. The A7 processor is accompanied by the M7 "motion co-processor", a dedicated processor for processing motion data from the iPhone's accelerometer and gyroscopes without requiring the attention of the main processor, which integrates with iOS 7's new CoreMotion APIs. The same A7 SoC and M7 motion co-processor are also found in the iPad Air and iPad Mini 2, both of which were released in the same quarter as the iPhone 5s.The phone includes a 1560 mAh battery, which provides 10 hours of talk time and 250 hours of standby time.
The home button on the iPhone 5s incorporates a fingerprint recognition system known as Touch ID, based on technology from AuthenTec, a company that Apple had acquired in 2012. The sensor uses a capacitive CMOS-based sensor which can detect the "sub-epidermal layers" of fingers at 500 pixels per inch, and uses a 360-degree design that can read the print at any angle. The sensor itself is activated by a touch-sensitive metallic ring surrounding the button. Touch ID can be used for various authentication activities within the operating system, such as unlocking the device or authenticating App Store and iTunes purchases instead of an Apple ID password. The sensor can be trained to recognize the fingerprints of multiple fingers and multiple users. Fingerprint data is stored in an encrypted format within a "secure enclave" of the A7 chip itself, and is not accessible to any other apps or servers.
Camera
Camera hardware
While the camera is still 8 megapixels in resolution with the image capture size of 3264 × 2448, the lens has a larger aperture and larger sized pixels in its image sensor than previous iPhone models. The flashlight has dual "True Tone" flashes, consisting of an amber LED and a white LED, which are variably used based on the color temperature of the photo to improve color balancing.Camera software
The camera software includes automatic digital image stabilization, dynamic tone mapping, 10 fps burst mode and slow motion video at 120 fps.Photos captured during the 1080p video recording have a resolution of 720p.
Slow-motion video
The iPhone 5s's camera was paired with a dual-LED flash, allowing for higher-quality nighttime photos. iOS 7 introduced a new camera app, allowing the iPhone 5s to capture fast continuous shots and record slow-motion videos with 720p at 120 frames per second and an audio track, making it the first iPhone to be able to record at any frame rate beyond 30 frames per second.An analysis by GSM Arena suggests that the image quality of the supposedly 720p slow-motion footage resembles approximately 480p.
