Critical reception (top) and iPhone 5s (middle) and the 30-pin port of the
iPhone 4s (bottom) The iPhone 5s received a positive reception from reviewers and commentators.
Walt Mossberg of
All Things Digital gave the phone a favorable review, saying that Touch ID "sounds like a gimmick, but it's a real advance, the biggest step ever in biometric authentication for everyday devices," and labeled it "the best smartphone on the market."
David Pogue of
The New York Times praised Touch ID, but said that the innovation of the smartphone market has been saturated, and "maybe the age of annual mega-leaps is over." He focused much of his review on iOS 7, which he believed was the biggest change of the device over previous generations, praising new Siri features, Control Center, and AirDrop. In an editorial, Pogue stated that iOS 7 was the biggest change in the iPhone series, citing utilitarian interface changes as the main contributor to this. Scott Stein of
CNET criticized the lack of design change over iPhone 5 and said that although the iPhone 5s "is not a required upgrade, but it's easily the fastest and most advanced Apple smartphone to date." Although praised for its camera, 64-bit A7 chip, M7 motion-chip, and fingerprint scanning capabilities, some investors thought that the iPhone 5s, although a notable improvement over the iPhone 5, was still relatively unchanged from its predecessor, and worried that the iPhone line had become a stagnant, dull product. Apple's share price fell 5.4% after the launch to close at a month low of $467.71 on the
NASDAQ. Darrell Etherington of
TechCrunch who praised the iPhone 5s as the best smartphone available said "looks may not be different from the iPhone 5, but the internal components have a dramatic impact on day-to-day activities normal for a smartphone user," and went into detail explaining the impact of the improved camera and specifications on the phone. Etherington suggested that the 64-bit A7 processor will not reach its full potential until developers create applications supporting it. Myriam Joire of
Engadget found that the iPhone 5s could benefit significantly from the A7 if developers created applications optimized for the 64-bit processor.
Anand Lal Shimpi of
AnandTech praised the phone's A7 processor, describing it as "seriously impressive", and stated that it was the most "futureproof of any iPhone ever launched. As much as it pains me to use the word futureproof if you are one of those people who likes to hold onto their device for a while – the iPhone 5s is as good a starting point as any." Scott Lowe of
IGN also spoke highly of its 64-bit processor, "which has a substantial lead in processing power over the
HTC One and
Samsung Galaxy S4, accounting for a graphics boost of up to 32% and 38% in CPU benchmarks." The debut of Apple's 64-bit A7 processor took rival Android smartphone makers by surprise, particularly
Qualcomm whose own 64-bit system-on-chip was not released until 2015. Most reviewers recommended the iPhone 5s over the iPhone 5c which was released at the same time. The 5c retained almost the same hardware as the discontinued iPhone 5, while the iPhone 5s featured substantially improved performance/features thanks to its new 64-bit A7 processor, as well as extra storage space, all for a relatively small additional upfront cost over the iPhone 5c (US$650 versus US$550 in March 2014). This was especially the case when iOS 8 was released and both iPhone 5s and iPhone 5c were moved to the mid and low end of the iPhone range, respectively; the iPhone 5s still had 16 or 32 GB (14.9 or 29.8
GiB) storage available while the iPhone 5c had to make do with 8 GB storage with only 4.9GB available to the user after installing iOS 8. Furthermore, the 5c's polycarbonate exterior received a mixed reception and was seen as a cost-cutting downgrade compared to the iPhone 5's aluminum/glass case; the 5s retained the latter design and looked even more premium due to its additional gold finish. As of 2015–16, there were still a significant number of customers who preferred the 4-inch screen size of iPhone 5s, which remained the second-most popular iPhone after the iPhone 6 and ahead of the iPhone 6s. Apple stated in their event that they sold 30 million 4-inch iPhones in 2015, even as that form factor was succeeded as the flagship iPhone by the redesigned larger display 4.7/5.5-inch
iPhone 6 and 6 Plus back in September 2014. Furthermore, the 5/5s design was regarded as "long been the golden child of Apple phone design and a benchmark for phones in general" (with the 5s's gold finish adding a premium touch to the 5's already well-regarded look), while the succeeding 6 and 6S design was less critically acclaimed as it "felt a little bit wrong, as though you were holding a slick $650 bar of soap". The iPhone 5 was described as "elegance rooted in the way the aluminum and glass work together. It felt streamlined, yet substantial, which is different from iPhone 6, which feels substantial in size alone. Plus, unlike the ubiquitous rounded corners of the 6, iPhone 5 didn't really look like anything else on the market at the time". However, the iPhone 5/5s design was not suited to scaling up, in contrast to the iPhone 6/6S which could better accommodate the growing consumer trend towards larger screen sizes and indeed spawned the 6/6S Plus
phablet models. When Apple discontinued the iPhone 5s, it was replaced by the
first-generation iPhone SE which outwardly appears almost identical to the 5s even as the SE's internal hardware has been upgraded significantly.
Commercial reception The iPhone 5s and 5c sold over nine million units in the first three days, setting a record for first weekend smartphone sales, with the 5s selling three times more units than the 5c. After the first day of release, 1% of all iPhones in the US were iPhone 5Ss, while 0.3% were iPhone 5Cs. Gene Munster of
Piper Jaffray reported that the line at the
Fifth Avenue Apple Store contained 1,417 people on release day, compared to 1,300 for the
iPhone 4 in 2010, and 549 for the
iPhone 3G in 2008 on their respective release days. This was the first time that Apple launched two models simultaneously. The first-day release in China also contributed to the record sales result. On launch day, major in-stock shortages were reported in most stores, across all countries where the iPhone 5s initially went on sale. A great many customers in line outside Apple Stores worldwide were left disappointed due to severe shortages across all 5s models, with the gold model in particular being in highly limited supply. While this situation eased in the US in the days following the launch, other countries reported receiving few restocks. Some commentators questioned how Apple handled the initial release, as online pre-orders were not offered for the iPhone 5s, meaning large numbers of people queuing outside physical stores, with most in line not receiving a unit. In the US, Apple offered an online reservation system, so customers could keep checking for units available at their local Apple Stores, and order for pickup. Online orders were also in short supply on launch day, with the shipping date across all model sizes and colors changing from "7-10 working days" to "October" in all countries, within hours of online orders being taken. The iPhone 5s was the best selling phone on
AT&T,
Sprint,
Verizon, and
T-Mobile in September 2013 in the United States, outselling the iPhone 5c and
Samsung Galaxy S4. According to Consumer Intelligence Research Partners, the iPhone 5s outsold the 5c by a two-to-one margin during its September release, confirming Apple CEO
Tim Cook's view that the high-end smartphone market was not reaching a point of
market saturation. While commentators viewed the 5c as a flop because of
supply chain cuts signifying a decline in demand, the 5s was viewed as a massive success. Apple admitted that it had failed to anticipate the sales ratio, leading to an overstocking of the 5c and shortages of the 5s. Six months after the release of the iPhone 5s, on March 25, 2014, Apple announced that sales of the iPhone brand had exceeded 500 million units. By May 2014, despite having been on the market for eight months, the iPhone 5s reportedly outsold the newly released
Samsung Galaxy S5 by 40%, with 7 million iPhone 5s units versus 5 million Galaxy S5 units. The Galaxy S5's failure to oust the iPhone 5s from the top-selling spot was a major setback for Samsung Mobile, as the preceding
Samsung Galaxy SIII and
Samsung Galaxy S4, in the first quarter of their releases, had outsold the
iPhone 4s and
iPhone 5 respectively.
Impact of Touch ID A number of technology writers, including Adrian Kingsley-Hughes of
ZDNet and Kevin Roose of
New York believed that the fingerprint scanning functionality of the iPhone 5s could help spur the adoption of the technology as an alternative to
passwords by mainstream users (especially in "
bring your own device" scenarios), as fingerprint-based authentication systems have only enjoyed wider usage in enterprise environments. However, citing research by biometrics engineer Geppy Parziale, Roose suggested that the CMOS-based sensor could become inaccurate and wear out over time unless Apple had designed the sensor to prevent this from occurring. Brent Kennedy, a researcher of the
United States Computer Emergency Readiness Team, recommended that users not immediately rely on the technology, citing the uncertainty over whether the system could properly reject a spoofed fingerprint. Following the release of the iPhone 5s, the German
Chaos Computer Club announced, on September 21, 2013, that they had bypassed Apple's new Touch ID fingerprint sensor by using "easy everyday means". The group explained that the security system had been defeated by photographing a fingerprint from a glass surface and using that captured image to make a latex model thumb which was then pressed against the sensor to gain access. The spokesman for the group stated, "We hope that this finally puts to rest the illusions people have about fingerprint biometrics. It is plain stupid to use something that you can't change and that you leave everywhere every day as a security token." Others have also tried Chaos Computer Club's method, but concluded that it is not an easy process in either time or effort, given that the user has to use a high resolution
photocopy of a complete fingerprint, special chemicals and expensive equipment, and because the spoofing process takes some time to achieve.
Problems Several problems were experienced with the iPhone 5s's hardware after its release. The most widely reported issue is that the angle reported by the phone's level sensor had drifted by several degrees, which caused the
gyroscope, compass, and
accelerometer to become inaccurate. Reports suggested that this is a hardware-induced problem. Some encountered other problems such as crashing with a blue screen and then restarting, the power button making a rattling noise when the phone was shaken, overheating, the microphone not working, and Touch ID not working for iTunes purchases. Some of these issues have since been fixed by software updates. == See also ==
