The app market is highly competitive, and to ensure your application’s success in the niche market, you need to test it thoroughly before launch. Mobile app testing ensures proper functioning, UI/UX usability, detects bugs, and identity the bottlenecks which can severely affect the app performance at later stages. A high-quality and functional app can increase ROI and improve conversion rates.
Testing application on an actual device is an integral part of the app testing process. It allows the QA team to validate the features of the app and check its functionality. Accurate device testing enables the tester to assess if the app will run smoothly in customer handsets.
Testing on emulators and simulators will not suffice as these are virtual devices, and it can only affirm the functionality, consistency, and usability of the app to a certain extent. Accurate device testing allows the testers to test almost all the real-time scenarios for mobile applications. It is impossible to emulate all mobile phone characteristics and provide an accurate mobile environment during the testing phase using an emulator or simulator.
The global mobile application market size is projected to reach $407.31 billion by 2026.  Companies aim to release successful apps that run smoothly on most of the target audience’s devices. Accurate device testing is resource-intensive and expensive. However, it has multiple benefits. You can also test on real devices online to verify your app’s performance, identify gaps, and check how it will perform in real-world scenarios.
Here are ten benefits of accurate device testing.

Usability Of App

Real device testing enables the QA team to test the usability issues of the app. The testers can prepare the test documentation and run it on real devices. Because of extreme device fragmentation in the mobile device market, the testers need to perform it on various instruments and browsers to provide a satisfactory user experience.
Accurate device testing helps validate the app’s look and feel screen color resolution, and if the picture has the proper visibility under both day and night conditions, and much more. Hence, real device testing helps to check the app’s usability to ensure the end-users total satisfaction.

Stringent Performance Testing

Accurate device testing helps measure the response time and availability of a mobile application’s key transactions under real-world scenarios. It enables the tester to check the app’s back-end and front-end performance in real mobile devices and various network conditions.


Testing on real devices is more reliable than the emulator or the simulators. Accurate device testing eliminates the chances of erratic test results. It gives an improved accuracy as compared to emulators and simulators. Emulator testing has multiple limitations that stem from not running the mobile OS on an actual device.
Similarly, a simulator loosely mimics the actual device’s behavior; it does not, however, develops a true copy of the mobile operating system. Hence, real devices are often the best platform for app testing.

You Run The Tests In Actual Conditions

The actual devices are operated using fingers, and it simulates real-life usage. Hence, it helps test the apps in a natural context, i.e., the application will be used in various conditions and environments. Therefore all the real-life conditions are considered, including network failures, weather conditions, and hardware issues.

Cross-Platform Testing

Real device testing of the app on different platforms, operating systems, and OS versions helps compare and analyze the app’s behavior in different environments. You do not have to worry about false positives and negatives, accurate device testing produces actual results, and all the performance defects in the device or the environment become visible.

Wide Coverage

With accurate device testing, you can make appropriate test cases to cover the maximum test scenarios required based on the current release. You can prepare a list of actual devices before you begin the test operation for improved test coverage.


You can test your app against various features and sensors on which your application relies extensively in accurate device testing. It is instrumental if your app has features that are dependent on specific sensor types. Testing on an actual device helps you determine how the app will behave when it coordinates with mobile features like GPS, camera, Bluetooth, fingerprint sensor.

Test Memory And Storage Requirement

Apps have specific hardware requirements such as memory, camera, and CPU. It tends to crash or run slow on the device, which has less memory (RAM). However, it can run smoothly on instruments with higher memory. Real device testing helps to check the hardware requirements of the app.

Accuracy Of Rendering Up To Each Pixel

Real device testing helps to check the brightness and screen resolution of the app using different lighting scenarios. Moreover, it helps to fully verify the accuracy of which the app renders to each pixel.

Recreate End-User Actions

Real device testing enables the tester to recreate the actions that consumers perform while using the app. Hence, it helps validate the apps’ performance against hardware interrupts such as SMS, calls, push notifications, etc.

To Conclude:

The satisfaction of the end-user is essential for the success of the applications. Real device testing helps to ensure how the performance of the app in real-world scenarios. It helps to check if the app runs without errors on real devices.
