The iPhone 16 and iOS 18 offer new challenges and opportunities in software testing. To ensure comprehensive device coverage and full compatibility with different test devices, developers and testers have to take specific requirements into account. How quickly do apps or websites need to be tested on new devices and versions? And how relevant are older versions of operating systems? Our devices expert answers these questions and more in the following interview.
Testing on the iPhone 16: How iOS 18 changes device coverage in software testing
With the introduction of iOS 18, the smartphone world is again facing an exciting change. The release doesn't just bring new features, but could also have a significant impact on the current market share of mobile operating systems - and therefore also on testing. Apple has always positioned itself as an innovator, and the latest update focuses on improved user-friendliness and security.
The new features for user interaction and personalised settings might lead Android users to consider switching to Apple. The trend towards more individualisation in software design is particularly appealing to younger target groups who value a unique user experience.
Furthermore, the robust integration of IoT functions in iOS 18 could boost the growth of the smart home market and strengthen Apple's market position significantly.
According to a recent survey by statcounter , the introduction of iOS 18 has begun, but the user base is still quite small because the version is in the initial phase of introduction. The significant majority of iOS users (approx. 66%) is still using iOS 17, followed by a market share of just under 7% for versions 16 and 15. In September 2024, only approx. 7% of users were using the new operating system 18.0. It is expected that the acceptance of iOS 18 will steadily increase over the course of the year when more users switch to the new version.

Although the level of acceptance is still low, the integration of iPhone 16 testing is crucial in order to incorporate this market development and ensure that apps run smoothly on all variants of this device. Software compatibility with iOS 18 is also an important factor, as apps and websites are also controlled via the latest version of the operating system. The changes in the user base have also impacted the test methods in user research and accessibility testing. In particular with regard to the digital barrier. A currently planned release should therefore also be tested on the latest version.
Ensure software compatibility with the right testing devices
Our Test Manager Oleg Kirillov is responsible for all issues relating to our large testing devices pool. In this interview, he reveals what has changed in software testing for apps and websites with the introduction of the new iPhone 16 and iOS 18.
How quickly are the new iPhones included in the testing process?
As soon as the new models are on the market, we order them. Once they arrive, they are set up and customised to our requirements. Afterwards, the new iPhone moves directly to our testing department and is integrated into our testing process for all mobile applications, from apps to websites.
Why is the fast integration so important?
As soon as a new device comes on the market, demand from numerous end users increases. We therefore react proactively to minimise the risk for our customers during testing. By immediately incorporating the latest device, we guarantee the quality and reliability of the products and secure important insights from a developer perspective. In this way, we ensure that the latest versions of operating systems are included in the test to ensure a planned release.
Why is it important to keep also older devices in the test pool?
It is essential to keep older mobile phones or tablets in our test pool because they are still available on the market and are used by a significant number of users. The new devices are first used by early adopters until the demand increases. Therefore, we need to ensure that our customers' products also work optimally on previous versions.
FAQs about software testing with the iPhone 16 and the new iOS 18 version
With the market launch of new devices and operating systems, we advise our partners on adapting their device coverage in software testing. Oleg answers three frequently asked questions about the changes caused by the new Apple operating system version 18.
Which iPhones will receive the new iOS 18 version?
The update is available for:
- iPhone 15, iPhone 15 Plus, Pro, Pro Max
- iPhone 14, iPhone 14 Plus, Pro, Pro Max
- iPhone 13, iPhone 13 mini, Pro, Pro Max
- iPhone 12, iPhone 12 mini, Pro, Pro Max
- iPhone 11, iPhone 11 Pro, Pro Max
- iPhone XS, iPhone XS Max
- iPhone XR
- iPhone SE (SE 2 and newer)
What happens if testing on new smartphones and iOS versions is disregarded?
Ignoring new devices and iOS versions in the test pool can lead to an increased number of errors, crashes and security problems. This primarily affects users of mobile applications. A negative user experience can not only damage brand perception, but also affect the overall corporate image and customer loyalty. This can ultimately have an impact on both competitiveness and sales.
Which resources are necessary for effective testing on new iOS versions?
First of all, access to the newest iOS devices is essential to carry out realistic tests. In addition, specialised testing tools are required to enable manual and automated testing as well as error tracking. A competent team of testers ensures that testing processes are continuously monitored and optimised. Investment in training is important to keep the team up to date with the latest developments and innovations.
