10 Tips To Choose Mobile Devices For Testing?

With the exponential growth of handheld devices, especially smartphones, users can access services from their homes’ convenience. Mobile applications are full of brilliant features and miscellaneous utilities. It enables business owners to improve brand visibility, add value, provide quality customer service, and optimize efficiency.

The app market is highly competitive, and most of the mobile apps launched in the app stores get abandoned after single-use. Apps fail to deliver optimum performance because most developers fail to provide a robust testing process promptly. Performing a thorough testing operation on the mobile device before launch enables the developers to address the performance gaps at early stages, identify and fix bottlenecks, and test app performance in real-world scenarios. 

App testing is performed to check the functionality, usability, UI, compatibility, performance, certifications, beta, localization, recovery, and security aspects of the app. It is pertinent for companies to check how the app runs on devices used by the target audience. To choose the top mobile testing devices for performing the test operations, you need to consider multiple factors. It will help you affirm the app’s functionality, consistency, and usability before it is launched. 

To determine what mobile devices you need to use for mobile application testing, you should consider the following factors.

OS And OS Versions

You need to check the performance of your app on different platforms. Hence it is necessary to run the test scripts on other OS and various versions. The QA team should test the app on multiple OS versions and should keep in mind the changes it may require to address the performance gaps. The QA team should acknowledge the wide range of operating system versions and devices in use. Focusing on a single platform can prove to be redundant as it can narrow down the perspective of the concerned app in the marketplace. Testing the app on different mobile devices, including other operating systems, helps to analyze the app’s behavior in different environments comprehensively. It enables the app to deliver an optimal user experience to the end-user independent of the OS used for accessing it. Use a testing tool that can help you run the scripts on different mobile devices and reuse test scripts any number of times to test the app’s performance and efficiency. 

Screen Size And Resolution

Mobile device comes in various sizes and resolutions. The QA team should consider the screen size of the devices to perform the UI compatibility test. Mobile devices should enable the tester to perform forward compatibility testing of their apps. Depending on the target device, choose the mobile device family’s appropriate devices, including Tablets, iPhones, iPods, and more, to increase the test coverage.


To select the right mobile device for testing your app, you need to consider miscellaneous attributes such as screen size, resolution, PPI, and other hardware features. Additionally, you need to determine the disk space and data consumed by the app. The processing power of mobile devices varies depending on their configurations which determines the performance of your app. Hence you need to test your app on diverse hardware. Apps generally have predetermined hardware requirements such as memory, camera, and CPU. If it is run on a device that has lower RAM, it may crash or run abnormally. Hence, identify the hardware requirements to choose the right device for mobile testing.

Who Does Your Product Target

To choose the right testing device, you need to determine your target users. If you are developing software, you are likely to target desktop users more than smartphone users. The travel website has an equal influence on desktops and smartphones. Based on what your software caters to, you need to choose the right testing device.


Based on the popular mobile brands in the niche market, you can choose a mobile device accordingly for testing. Identify the device combination that can get you the broadest coverage in terms of model and brand. Based on this data, you can categorize the devices as important, secondary, or additional.

Market share

You can select devices based on how popular they are in the geographical markets that you are targeting. Ensure that you are listing all the popular devices relevant to your need. You can research the market share of each device to choose target devices.


Cost is an essential parameter for choosing the correct device for testing. Based on the budget you can allocate for the testing process, you can select the most critical devices for testing your app.


Analytics tool helps to identify and gather user data to determine the base of your target customer. It enables you to collect data about your end-users demographics, age, gender, and other such attributes. You can determine who visits your application and on what kind of mobile device. It also gives you an insight into additional data about the service provider, OS, mobile brand, and screen resolutions. 

Device Features 

You can test your app against various features and sensors on which your application relies extensively. You need to identify sensors and sensor capabilities at runtime and test your app against certain features like GPS, camera, Bluetooth, fingerprint sensor to check its performance.


To select a suitable device, consider the types of devices and features coming shortly. It helps you to determine if the app can support such advanced features without any glitches.

To Conclude:

Mobile device testing enables the tester to check the performance of the app in real-time scenarios. The satisfaction of the end-user is critical for the success of the app.
