What Developers need to know about mobile app performance?


According to ClearTrip’s research, most users delete an app due to a bad user experience. This is due to the app’s poor optimization. Many users needed help with the sudden freezing of applications, which depleted the battery too quickly, and many more due to a lack of good optimization in older versions of Android.

App optimization is the process of making changes to an app so that it may be installed and run without any problems, and it can be achieved through performance testing. Optimizing should take as little time as possible, so developers should make that a priority.

Why Mobile App Optimization?

Boost Speed

Optimizing applications before their release increases their speed. The applications launch and shut down more quickly since they are already optimized before launch.

Preloads an App Element

As with the files of the codex, the extension expedites the booting process and is only a collection of files that complete the optimization process. It also allows the system to launch applications in much less time. You could achieve this by optimizing through automated mobile app testing before launching.

Prepare the App for Execution

During the optimization process, portions of the application are loaded in advance, preparing it for execution when the user turns on the machine.

Extension of Battery Life

Optimizing these programs prior reduces the device’s demand, extending the battery life.

What are the components of app optimization?

The Internet

Bandwidth inconsistency, fluctuating congestion, and increased latency could all significantly affect application performance.

Components of Third Parties

If your system relies on data from a third party and that third party becomes inaccessible, your plan may collapse entirely. Similarly, bad performance by a third party often has a domino impact on the performance of your system.

User Behavior

It is crucial to comprehend actual user transactions and activity flows to minimize performance bottlenecks during high-use times.

How to optimize mobile app performance?

Let’s look at several methods for enhancing the performance of your mobile application.

Use a CDN to accelerate APIs

Programming interfaces are in charge of relaying and presenting data gathered by other programs. If you’ve ever used a weather or traffic app, an API was responsible for retrieving and displaying the third-party data from the native app. Content delivery networks or CDNs expedite the process of an API, which is why they are advantageous. A CDN utilizes global servers to speed up API connectivity. An edge server geographically proximate to the user mitigates latency, round-trip time, payload, and size. Essentially, the distance to the user is decreased, resulting in a speed increase for the API.

Optimize images

The larger the picture, the longer it will take to load and the slower your application will run while attempting to show it. This load time will be minimal if you optimize your photos properly. Consider optimization as a three-step procedure:

  • Compression
  • Resizing
  • Caching

Optimization of these elements reduces the effort required by your mobile app to load assets. The outcome is speedier load times and an improved user experience.

Reduce unnecessary characteristics

While developing a mobile app, it is crucial to eliminate as much unnecessary functionality as feasible. If a feature isn’t critical to the program’s performance, remove it to improve your overall performance.

Load data as required

Loading an application’s data at once might cause it to stutter or crash. Instead of processing vast amounts of data simultaneously, consider utilizing split-up assemblies to break the data into manageable pieces. This enables you to prioritize the loading of the app’s most crucial processes, allowing less vital activities to load as required.

Establish an offline mode

The offline mode of an application is intended to save your data securely if a network connection is lost. Without an offline mode, all app data is lost in the case of a sudden loss of connectivity. This might cause significant difficulties for the user. By implementing an offline mode, you enable the user to preserve their data and access it once they are connected again. It entails dependability, information security, and user convenience.

Test your app across numerous devices

Remember that not everyone will use your app in the same manner or on the same device, so it is necessary to test it thoroughly to ensure it functions as intended. It is crucial at this point to test your app on numerous devices. Mobile app testing assures that your final product will work as designed regardless of the device used by your user base. It will offer you a sense of your app’s performance across various battery lifetimes and technologies, ensuring your user experience remains constant in all conditions.

Monitor the crashes

Monitoring your app’s crash reports can guarantee that you are aware of any difficulties that may arise after it is released. Unfortunately, as it may be, testing only catches some possible circumstances. Hence there may be crashes. It is essential to monitor them and identify the underlying causes. Crashing may occur for a variety of reasons. Your task is to determine why they occur and prevent them from happening again for the exact cause.

Show a loading status

Displaying a loading condition with a beautiful animation or informative text is a fantastic method to assist consumers in enduring the wait. Even though showing a loading status does not physically reduce load times, it does affect the user’s impression of the delay. Suppose your audience sees a blank screen while your app loads; they will perceive the load time as being longer than it is. In addition, if you provide feedback, customers can understand the load time for a freeze and retain your application.


Internet-connected devices are increasing exponentially, but users’ attention spans are decreasing. Only a well-performing mobile app can keep them coming back. Always remember to use these standards as a guide while developing apps. Use a performance testing tool like HeadSpin for quicker and more accurate results. Please take advantage of cutting-edge AI features to promptly spot performance problems in testing before they affect consumers.

I started my journey as a Photoshop & HTML designer, my hunger takes me to the next step for PHP, Java, angular, CMS, Python, etc. Till now, I have worked on many software, mobile, web development & design projects. I want to inspire others, that's the only reason I am here to share my experience & knowledge. Let's connect on LinkedIn.
