The ideal does not exist, especially in the world of high technologies, but the desire to achieve it is a completely natural process, which, apparently, was forgotten in the California corporation Apple. The company undermines the reputation of its most advanced operating system from year to year.
iOS 9 for iPhone, iPad, iPod touch was released in September 2015 and covered a massive lineup, including older devices such as the iPhone 5S. Usually, questions regarding whether it is worth updating or not have never arisen, but more and more often users have begun to probe the soil and get acquainted with new software based on other people's experience.
This material is dedicated to all doubters and those who want to learn more about the system. We will conduct a brief review and tell you what iOS 9 reviews have. OS is very ambiguous, therefore it is worthwhile to dwell on the features and capabilities of the product in more detail.
Key innovations in the system
In the new update, programmers from Cupertino were finally able to realize a lot of features that have long been expected by the bulk of users. For example, full interaction with iCloud Drive. In addition to the ability to embed the "apple" cloud in third-party applications, a full-fledged application has appeared that allows you to directly interact with the files that are stored in it. Spotlight has new features that can now perform simple calculations, search for data in third-party programs, and even on the Internet. There is such a novelty as proactivity. The smartphone began to predict user actions, recommending suitable programs, activating the player when connecting headphones and the like. For the first time in 9 iterations, iOS received an energy-saving mode, which is designed to save power by blocking background activity and graphical research. There were also opportunities whose work on the iPhone 5 S was in question.

Seeing the list of innovations, many users were puzzled by the question: “How does iOS 9 work on the iPhone 5 S?”
Night shift
Thanks to the presence of a processor that supports 64-bit architecture, this feature has become available to all the happy owners of the iPhone 5 S. Night Shift (“Night Shift”) is a gradual change in white balance displayed on the display with a shift in the “warm” range. It is scientifically proven that the displays of modern gadgets negatively affect a person’s ability to fall asleep, and one of the reasons for this is called the radiation of the blue spectrum emanating from them. Night Shift allows you to weaken the “cold” tones, making the use of the gadget more comfortable at night and helping the user fall asleep. It is difficult to say that it is more difficult to plunge into the arms of Morpheus: a blue glow or another post in the networks, but many market players followed the example of Apple, introducing similar functionality into their devices.
Content Blockers in Safari
64-bit architecture also played into the hands of the gadget owners. The modern Internet is literally teeming with advertising, and Apple understands this, therefore they allowed it to make extensions for its browser that can block various types of content, including ads, banners, Javascript, and so on. The function has found a demand among the owners of the iPhone 5 S and is actively used. Ad blocking allows you to reduce the load on the processor, reduce the consumption of Internet traffic, increase the duration of the battery life.
Handwritten notes
Another feature that owners of previous generation devices did not get was the ability to sketch and draw in the standard Notes application. The function was liked by many owners of the iPhone, while it turned out to be difficult enough to run one on older devices, so iPhone 5 S users should definitely be congratulated: their gadget is still in the forefront.
System errors
The ninth edition of the operating system from Cupertino has rightfully earned the title, perhaps the most unstable, filled with a lot of errors and misunderstandings that have a negative impact on the user experience. At the time of release, reviews about iOS 9 ranged from just bad to extremely negative. The list of the most obvious problems included:
- Automatically turning on CAPS LOCK. This problem has gotten a lot of nerves for Russian-speaking users. Each time you try to enter a search query in Safari or write a message on Twitter, the keyboard automatically goes into CAPS LOCK mode, which had to be disabled manually. After the critical update iOS 9.0.2 for iPad, iPhone, iPod touch, the problem remained, which completely tarnished the reputation of the company and Apple products (in particular, the operating system).
- Memory leaks. The second, but not the least, problem is the widespread problem of excessive RAM absorption by the basic components of the system. The problem affected both gadget users and developers who faced a previously unknown task and were forced to re-optimize the software or restrict access to it on older devices. Alas, gadgets with one gigabyte of RAM, such as the iPhone 5 S, were the most sensitive.
- Activation Issues. Another problem that has received wide resonance is the cumulative update of iOS 9.3, which led to the deactivation of devices. This was observed on many devices of the company, it is possible that the owners of the iPhone 5 S encountered an unpleasant phenomenon.
Frame frequency
Despite the fact that global changes in the design of the operating system (the appearance of transparency, updated animation, and others like them) took place in iOS 7, each update loads the video subsystem more and more, slowing down the operation of system components and standard applications. iOS 9 was no exception, and even the iPhone 5S, which, it would seem, is equipped with a fairly powerful processor and graphics, felt the influence of time.
The overall frame rate has not dropped, the system works smoothly, responds to clicks in time, but when using a number of applications, such as “Music”, or entering the multitasking menu, the frame rate drops noticeably. In the case when the pictures begin to change too slowly, the user sees how the system interface “lags” and “slows down”. Most often, losses are noticeable when scrolling, large lists are difficult even to modern gadgets, to say nothing of the device three years ago.
iOS 9 on iPhone 5 S: performance reviews
Despite the problem with frame rate subsidence described above, the iPhone 5 S does a lot better than its predecessor. Users, in addition to smooth operation, note a quick response and program loading. More or less serious products, such as GarageBand, are not limited in their capabilities and process data at a relatively high speed.
Serious problems were encountered by those who upgraded to the new firmware urgently, without waiting for patches and without “cleaning” the system. Due to the incorrect sequence of installing or restoring data from the cloud, the system did not manage to index all the data and in the early days showed extremely deplorable results in terms of performance and operating time. Perhaps, in view of these circumstances, a stream of criticism fell in the direction of iOS 9 on iPhone 5 S. User reviews were saturated with disappointment, despite the fact that to solve their problems it was enough to simply “reset” the gadget. You can do this on the smartphone itself, for this you need:
- Open the Settings app.
- Go to the “General” menu.
- Then go to the “Reset” submenu.
- Then select the “Reset content and settings” sub-item and enter the password for your Apple ID account.
This procedure prevented a lot of problems and the unpredictable behavior of iOS 9 on iPhone 5 S.
System reviews
Users were ambivalent about the update, and it was not only a matter of performance, but also of the health of the applications. Many third-party programs refused to function properly after the update, which caused another wave of criticism on the Internet. The problem of sudden “crashes” could be attributed to poor optimization by the developers of the applications themselves, but it also arose when working with standard programs.
Also, users could not fail to note the fact that the battery charge began to melt literally before our eyes. This problem, like most others, is associated with indexing and incompatibility of content that migrated from the last iteration of the platform. The trouble is solved by a complete reset of all settings with the removal of content.
After the release of a series of critical updates, many problems disappeared into oblivion, and third-party developers immediately pulled themselves together to help optimize the system. How does iOS 9 work on the iPhone 5 S? Feedback from users can be compared with comments in the era of iPhone 4s and sudden changes in iOS 7. The gadget is not yet outdated to completely lose ground, but it already makes it clear that you need to prepare for a major acquisition. Reinforce this position and reviews about iOS 9, tirelessly stating that the phone is over. Of course, the decision to accept each individual user. As for the owners of the iPhone 5 S, there is nothing to fear: it’s worth the risk.
