Why is Mobile App Performance Important for Mobile Testing Success?

Mobile applications nowadays serve more purposes than they used to once. At present, we have applications for almost everything. This factor itself stresses the fact that how necessary is mobile app testing to stay in the market. Mobility teams must meet strict deadlines, and testing an app’s performance is of the utmost importance to them. Sometimes passing the functional tests meets all the critical criteria for releasing an app. But it is not always so. Performance testing tool is essential for determining the application’s stability under high-load situations, among other things. As a result, using a mobile app performance testing tool is critical to evaluate the app’s performance.


Certain factors must be considered during performance monitoring to maximize user experience. These include monitoring performance, test automation platform, stability, and resource consumption in real-time from the user’s perspective,-how the user experiences them. It is critical to figure out how many people were affected by slowness and what behavior on a specific operating system caused the disturbance. Various tools for mobile testing are available, which help one to solve the problems. For better clarity, one should check their app’s performance as follows:

Calculate the frame rendering time

Only monitoring network time is insufficient for users who want to know when the network restarts and replies.

Measuring reaction time per device or operating system helps the product manager to concentrate on one platform at a time, respond to performance concerns, and deploy resources as needed.

Calculate battery usage

It’s critical to track your mobile app’s battery use, data plan effect, and memory utilization. If the app is causing your battery to drain, you should update it to comply with best practices. Reducing frequent updates also leads to user happiness. 

Calculate cell data usage

According to Statista,2021 witnessed 4.32 billion unique mobile internet users indicating 90% of the global internet population. This means you should track the total number of users, KBs of data consumed each minute, the quantity of data transmitted every hit, and the percentage consumed per hit. There are tools for mobile testing that help in fixing such issues.

Errors in measurement

HTTP failures from specific URLs must be recorded. This will aid in tracking the number of users who received an error, the activities that caused it, the number of users that experienced errors upon app opening, the proportion of actions that resulted in at least one mistake, and the app version.


1. Speed triumphs

According to Compuware research, users anticipate their apps to launch in roughly two seconds. This is supported by Google SEO reports, which regard site speed as a critical factor in Page ranking.

Mobility teams must realize that their users want their apps to react in two seconds or less. Anything more than two seconds might cost you your company.

Users will switch to the rival app if the app takes more than five or ten seconds.

2. Mobile app error rates are most likely significantly more significant than they appear

You must have encountered problems such as photos not loading, network failures, content feeds leaving blank gaps in the app, timeouts, crashes, freezing, upload failure, etc. These difficulties are caused by poor networks mostly rather than app failures.

The error rates vary greatly depending on network conditions. Failure to measure and address mobile app errors will quickly result in frustrated customers, uninstalls, and 1-star reviews in app stores. Nobody wants that.

3. 5-star app rating

Reviews and ratings have become crucial factors in every user’s decision before installing your app. And the app should be flawless in every manner to receive a five-star rating.

If you focus on functional tests and ignore mobile app performance, you may find that your Play Store is filled with bad reviews even before you advertise it properly.

4. App Performance During Manual Testing

While running functional tests, the performance of an app may be monitored in real-time. Choose the program installed on the device from the Tools area to see a graph of Memory and CPU utilization, as well as the packets/bytes consumed in the Data Usage.

5. Battery Consumption 

The graph of Battery Consumption shows Battery Consumption by Device, Battery Consumption by Application, and Battery Consumption in %.

6. Consumption of Memory

An app’s CPU use is represented as Memory consumption in ‘Mb’ versus Time Duration in seconds.


Poor ratings on the Software Store or Google Play are general concerns about crashes, poor performance, or excessive battery drain, which could have been prevented if the app had been well-tested. A mobile app development business that isn’t concerned about quality is unlikely to succeed, wiping out all of your hard work. Here are just a few of the advantages of mobile app testing.

Better UI/UX Testing 

QA engineers can place themselves in users’ shoes and evaluate the whole app experience. They investigate the application’s logic and confirm that it is simple and easy to use. It would help if you executed UI and UX testing across the whole product life cycle to get excellent outcomes.

Loyal Customers

It is all about the users. People who like an app will continue to use it and suggest it to their friends. This can help your company establish a good reputation in the market and reach a larger audience. However, if your software irritates customers, you will always show a moderate degree of loyalty. So, test frequently and thoroughly.

Proper operation

QAs aims to ensure that an app runs smoothly. They test if an application functions correctly under certain performance constraints, such as changing load situations or networks. Each QA team determines whether to use genuine devices or emulators for testing.


The ultimate aim for a developer is for more users to use your application, which is very unlikely if the app is not good(compared to the competitor’s). That is why mobile app testing is critical. A unique stance in a busy market can only be created with scalable, user-friendly, and high-quality applications. Mobile app testing is a complex process. However, if an effective testing plan is incorporated into the app creation process, a five-star rated app will rocket to the top of the marketplace ranking. Test automation platform HeadSpin allows one to optimize internet encounters with mobile app performance testing by finding and addressing performance issues across apps, devices, and networks.
