iPhone 5

The iPhone 5 is a smartphone that was designed and marketed by Apple Inc. It is the sixth generation of the iPhone, succeeding the iPhone 4S and preceding the iPhone 5S and iPhone 5C. Formally unveiled as part of a press event on September 12, 2012, it was released on September 21, 2012. It was the first iPhone to be completely developed under the guidance of Tim Cook and the last iPhone to be overseen by Steve Jobs.

The iPhone 5 featured major design changes in comparison to its predecessor. These included an aluminum-based body which was thinner and lighter than previous models, a taller screen with a nearly 9:16 aspect ratio, the Apple A6 system-on-chip, LTE support, and Lightning, a new compact dock connector which replaced the 30-pin design used by previous iPhone models. This was the second Apple phone to include its new Sony made 8MP camera, which was first introduced on the iPhone 4S.

Apple began taking pre-orders on September 14, 2012, and over two million were received within 24 hours. Initial demand for the iPhone 5 exceeded the supply available at launch on September 21, 2012, and was described by Apple as “extraordinary”, with pre-orders having sold twenty times faster than its predecessors. While reception to the iPhone 5 was generally positive, consumers and reviewers noted hardware issues, such as an unintended purple hue in photos taken, and the phone’s coating being prone to chipping. Reception was also mixed over Apple’s decision to switch to a different dock connector design, as the change affected iPhone 5’s compatibility with accessories that were otherwise compatible with previous iterations of the line.

The iPhone 5 was officially discontinued by Apple on September 10, 2013 with the announcement of its successors, the iPhone 5S and the iPhone 5C. The iPhone 5 is the shortest lifespan of any iPhone ever produced with only twelve months in production and it is the second iPhone to support five major versions of iOS: 6, 7, 8, 9, and 10 after the iPhone 4S.

Hardware

The iPhone 5 uses a system on chip (SoC), called the Apple A6. The SoC comprises a 1.3 GHz dual-core processor, 1GB of RAM and a tri-core PowerVR SGX543MP4 running at 266 MHz. The iPhone 5‘s operating memory (LPDDR2-1066 eDRAM) was doubled, from 512 MB to 1 GB. Storage capacities available are fixed at 16, 32 or 64 GB, the same as the 4S; plug-in memory cards are not supported. The two color options are black (with black glass and slate-colored metal trim), and white (with white ceramic and silver-colored metal trim); again the same color options (though differently implemented) as its predecessor the 4S had. The iPhone 5 retains the 8 megapixel back camera on the iPhone 4S, but has improved low-light performance, and has a 40% faster photo capture than its predecessors, while having a purple hue when a strong source of light is present in the photograph. The front camera, which is accessible through the FaceTime and camera app has a lower resolution, at 1.2 megapixels. The rechargeable lithium-ion battery with a charge capacity of 1440mAh is built in and cannot be replaced by the user; it is rated at ≤225 hours of standby time and ≤8 hours of talk time. There are three separate models of the phone available: one supporting CDMA and two GSM versions. This can have knock-on effects for which version of the device will actually work in which countries/regions.[citation needed] The phone takes a nano-SIM, smaller than the micro-SIM of the iPhone 4 and iPhone 4S.

Hardware benchmarking conducted using Geekbench and GLBenchmark validates several claims that Apple included on their website and mentioned at the unveiling of the device, these include two times faster and two times the graphics performance. In the Geekbench overall hardware assessment, the iPhone 5 received a score that was approximately 2.5 times higher than the iPhone 4S. The benchmark conducted using GLBenchmark for the iPhone 5 returned a score that was 2 times better than the iPhone 4S. The result was however inconsistent as a 3D graphics benchmark assessment using Passmark returned a score that was only approximately 1.45 times better than the iPhone 4S. Battery life assessments conducted by AnandTech concluded that the battery life is shorter on the iPhone 5 than its predecessor when performing certain tasks, however when performing other tasks the iPhone 5 battery outlasts the iPhone 4S.

The Retina Display is 1,136 × 640 pixels with an aspect ratio of almost exactly 16:9, (minus one extra row of horizontal pixels). With a diagonal of 4″ it has a display size of 6.7 square inches, compared to 5.7 in iPhone 4 and 4S. The pixel density remains the same as the 4S model, which is 326 pixels per inch. Screen icons of the iPhone 5 are arranged in a matrix of six rows of four icons each. The increased screen size allows the sixth row of icons to be added to the five rows that were present in the iPhone 4. In-cell touch sensor technology from Sharp slims the screen which allows for a thinner phone. The screen’s color saturation is 44% greater than its predecessor.

There are three microphones (placed on the front, side and back) for noise cancellation and video calls.

On April 28, 2014, Apple initiated an out of warranty recall program to replace any failing power buttons of iPhone 5 models which were manufactured prior to March 2013 at no cost.

On August 23, 2014, Apple announced a program to replace batteries of iPhone 5 models that “may suddenly experience shorter battery life or need to be charged more frequently” which were sold between September 2012 and January 2013.
