Challenges to Mobile App Performance Testing


5 min read

Whether utilizing a mobile application or a mobile browser, consumers of mobile devices have high-performance expectations. The marketplaces for mobile apps are crowded with competing options; if you want to be seen on a customer’s smartphone, you must prove yourself.

Although assessing the performance of mobile apps is difficult, putting it off would be a grave error. Users won’t hesitate to uninstall your software if it doesn’t perform to their satisfaction. They can discover a better smartphone app given the abundance of options available.

It’s essential to continuously assess the performance of your mobile application if you don’t want this to occur. In addition to discussing key performance indicators (KPIs) used to gauge and assess application behavior, this article will also look at potential challenges when undertaking performance testing for mobile applications.

What is Mobile App Performance Testing?

Performance testing, a non-functional software testing technique, looks at how well an application’s stability, speed, UI performance testing, scalability, and responsiveness hold up under the workload threshold. Therefore, it is often referred to as load testing. Performance testing is only performed after functional testing, which is essential in guaranteeing software quality.

Performance testing is essential since it determines how long an app will last in various contexts. As each application type interacts with the server and the device differently, proper mobile application performance testing necessitates testing the program across all application types to verify performance.

Additionally, applications impose different usage requirements depending on the device’s specs. Testing must consider customer trends for mobile devices to provide an adequate sample size for performance testing.

Requirements for Mobile Apps Performance Testing

Users should take into account the following prerequisites as a starting point to ensure that device performance testing for a particular mobile application is effective and valuable:

  • Select the range of devices you will be testing: Testers can decide what tool capabilities are necessary and whether the testing procedures can be streamlined based on the target audience for the mobile app. For instance, an app being released exclusively for Android devices does not need to be tested on other operating systems. This gives testers more knowledge of their tool requirements and enables them to speed up the testing process.

  • Decide which individual software features require evaluation: This may involve analyzing app launch times, battery and CPU consumption data, operation and retrieval from the background, and more, depending on the individual features of the mobile app.

  • Pick a performance testing tool: Testers can choose the device that best meets their needs based on the previously defined testing scope. This entails considering additional preferences, such as the capacity to do cloud-based testing and matching the needs of mobile operating systems and application types with a tool that can support them.

Challenges in mobile app performance testing

It cannot be easy to test a mobile app. Several problems appear during performance tests. Here are a couple of these difficulties:

  1. Different Networks and Connectivities
    Quick access to information is made possible by the portability of handheld devices, although network circumstances can differ in terms of service provider, speed (2G, 3G, 4G, LTE), bandwidth, and stability. The mobile application must be evaluated under varied network conditions to ascertain the resulting load and reaction time.

    Particularly when traveling, mobile devices may operate some programs with sporadic connections or even offline. Client-server communication will be impacted by the reliability of the network connections in this case, which will also affect data transmission and application performance as a whole. Applications must be tested under various network situations to ensure that the latency and application experience are acceptable.

  2. Different Application Types

    The performance of multiple application platforms should be tested, which is another factor unique to mobile devices. Mobile web and native applications must undergo independent testing. Compared to mobile browser-based apps, native applications operate on a platform installed directly on the device.

    For browser-server applications, where performance depends on the server and network connection, different mobile browser types must also be considered while testing the application’s performance. Browser-based apps require connectivity, but native apps store data locally on the device.

    On the other hand, when several programs are operating simultaneously on the device, the type of application will behave differently. Thus, various client-server response times, device utilization, and overall performance must be assessed.

  3. Range of Mobile Devices

    Mobile devices are available in various screen resolutions, software versions, operating systems (iOS, Android, and Windows), and hardware specs (RAM, CPU, processors). The performance of the application needs to be evaluated across a range of mobile platforms to ensure, for instance, that it functions consistently for users of Android and iPhone devices.

    Screen sizes and resolutions range among different devices. Performance testing must ensure that an app can be successfully loaded on a mobile device and can adapt to different screen sizes. The application must run smoothly on all screen sizes without compromising its usability, graphics quality, or other visual performance elements. The iOS operating system, where iPhones come in various sizes with each iteration, is a clear illustration.

    However, performance testing on actual hardware could take a while and be expensive. The tester may instead indicate the minimal hardware requirements for the application to execute to reduce the number of mobile devices evaluated.


Software performance testing is an important step that must be taken to make sure the app is helpful and produces the desired outcome. The average crash time, the app’s reaction time, and network problems are just a few metrics that may be checked with a mobile app performance test.

A successful app will guarantee increased downloads, referrals, and popularity, resulting in a thriving business. Planning and strategy-making are pretty important. When creating a performance test, the developer must carefully evaluate all the relevant areas, such as various devices, critical performance aspects, and scenario priority.
