Look around, and you will find people engrossed in their mobile phones. Some order items online, and some play games on their mobile phones. Some buy or sell stocks, and some chat with their friends.

One common factor from all these scenarios is that they all use mobile apps to perform these activities.

Mobile apps are everywhere. From checking your horoscope to performing simple banking operations, you have a dedicated mobile app to rely on.

Even businesses now understand the importance of having a mobile app to streamline processes and serve their customers better. A good-quality and feature-rich mobile app can help startups and entrepreneurs target their audience and have the best engagement.

All you need is a competent mobile app development company. Discuss your requirements with them, and they will guide you well.

However, just developing and launching a mobile app is not enough. The Google and Apple Stores have millions of mobile applications. You will even find hundreds of mobile apps belonging to your category. It is essential to ensure that your mobile app ranks higher on these stores.

For that, you will be required to practise performance optimization techniques. You must develop mobile apps that load fast and offer excellent performance.

Almost 70% of users switch away from a mobile app due to poor performance. Also, it is about more than just speed; your app must manage massive traffic without compromising performance and a seamless user experience.

You must follow the best mobile app performance optimization techniques to ensure its success. From analysing user behaviour and persona to optimising your app's code to regular performance monitoring, you must keep everything in check to provide a satisfactory user experience for your audience.

Best App Performance Optimization Tips and Tricks

This post discusses success-driven app store optimization techniques for businesses to help them rank higher in app stores. However, before that, we will discuss the importance of app store optimization.

1. Try to Minimise The Application Size

The first thing you can do is minimise the app's size if possible. Mobile apps are not yet as powerful as GPUs. Also, if you have an Android app, the devices might not be as configured as iOS devices.
Also, some phones might not support 4G or 5G connectivity. Considering all these things, you must keep the app's size minimal. Users with low-configured mobile phones should be able to download and use the app without any hurdles.

2. Reduce The Loading Time

If your app does not load fast, users will lose interest. You must expect more downloads and engagement with a quick loading time. You have to reduce the loading time to 2 to 3 seconds. What can you do to minimise the app's loading time? Here is a list of tips you can do:

- Keep deleting outdated cache data to kickstart the app instantly.

- Avoid heavy activities until the first screen is rendered on the screen.

- Ensure that the data of specific heavy pages loads when those pages are opened.

- Use splash screens to let users perceive that the app is highly responsive and fast.

3. Improve Client-Server Interaction

You will do plenty of things simultaneously when you work on client-server interaction. First, you will reduce latency, improving the app's performance. Second, you will also enhance data transfer efficiency. It will provide a seamless user experience and make the app more responsive.

Quick and seamless communication between the client and server will improve the app's performance and productivity. Here is a list of tips to enhance client-server interaction.

Minimise the data sent to users and optimise the client-server API to improve the loading speed.
Load data only when it is necessary to improve efficiency and performance.
Test your app regularly on poor networks to ensure speed and performance.
Use CDN to reduce data loading time by shortening the distance between users and data sources.
Go for pagination to manage large data volumes in the news feed.

4. Conduct Performance Testing

This is the essential step before you launch your app. Most developers conduct performance testing before the app deployment to ensure no bottlenecks, bugs, or other issues. A thorough performance testing will reveal many things like response time, memory usage, etc.

Performance testing must be conducted throughout the app development process to quickly identify and address performance issues.

5. Minimise Battery drain

Battery draining is another crucial aspect that developers must address accurately. You can minimise battery draining by performing various tasks like using proper and accurate coding techniques, limiting background processes, and reducing the use of animations, images, and other visual effects. Users would prefer mobile apps that don't drain the battery quickly.

6. Optimise Your App for Various Devices

One of the most common mistakes developers make is deploying the app before testing it on various devices. For example, most Android phones have different specifications, like screen sizes, memory, versions, etc. Not testing your app for these devices would be a rookie mistake.

You must check how well the app performs on these mobile devices. If it is not, you need to optimise the app accordingly. It will guarantee a seamless user experience for your users using different devices. It will lead to more engagement and revenues.

7. Optimise App Architecture

Developers must also optimise the app's architecture as it will affect its startup time, speed, and performance. Also, a mobile app with an optimised architecture is easy to maintain and update. Developers can quickly change the app's code to ensure high-speed performance.

The reason to work on the app's architecture is that the app's startup time is crucial in ensuring high engagement. Users want the app to load quickly; if it does not, they will get frustrated. They might abandon the app and, in some extreme situations, uninstall it. You cannot let it happen.

To optimise the app's architecture, go for the Model View Controller design pattern that divides the app into three components: Model, View, and Controller. Developers can build a high-performing app by optimising these three components separately and independently.
An epitome of strong structures relieves update and maintenance work on the app ensuring efficiency despite additions of new features or changes therein. The Model View Controller (MVC) design pattern has been found to be one of the best methods in optimising architecture. Essentially,MVC splashes the application into three separate sections: Model, View and Controller.Making it easier to manage by having each component developed independently optimises modularity thereby making it easier to use (Awan, Fatima, and Doda 1).

Websites need to be alive in order for them not only to manage properly with information they have but allow users new capabilities such as scaling quickly and high performance consistently through these components optimization.

8. Go For Performance-Oriented Design:

Keep performance in mind while designing the app. Discuss it in detail with the iOS app development company you have hired. Now, what is performance-oriented design?

It means designing the app while considering various aspects, such as user experience, persona, data usage, latency, etc. Here is a list of design tips for you.

- Only use highly-optimised images, graphics, and videos.

- Use only a few animations and transitions.

- Use the lazy loading feature to reduce data storage.

- Design and test the app for low network connectivity to ensure high speed and performance.

When you go for a performance-oriented design, you will be able to create an app that meets the expectations of your target audience.

Amazon is the best example of performance-oriented design. Amazon uses highly optimised images and graphics and keeps animations

smaller. We enjoy using Amazon, don't we?

Since the mobile application is to be made available to a wide public as for instance, accepting and processing of images, the app should not get dragged down in any way because of them. Lazy loading can help reduce data storage space and lag time between loading, since it only loads what is necessary at that moment. Furthermore, its design must be tested under different circumstances like poor quality internet connections ensuring that it performs effectively when network situations are not perfect enough.

9. Optimise Images and Other Visual Items

Most of the time, images slow down the app as big-sized images and other visual items increase the loading time, making it slow. It also affects the overall user experience as well. The best thing to handle this issue is to optimise the images and other visual things like videos, animations, etc.

Also, optimised images help conserve bandwidth and storage space and improve the app's loading time and performance. How do you optimise images?

- Use only vector images to load the app quickly.

- Reduce the image size before uploading them.

- Use various available libraries like Picasso and Fresco to optimise images.

There is an effective way of doing it which involves the usage of vector graphics as opposed to raster graphics. Unlike raster graphics that can distort when zoomed-in or zoomed-out, vector graphics retain their initial shape irrespective of whether the user zooms in or out on them thus helping in maintaining a quick loading time throughout different devices’ screen sizes. Furthermore, another approach would be to minimize image file size prior to uploading the images into the application. Developers may make use of image optimisation libraries such as Picasso and Fresco in order to automatically compress and optimize images resulting in faster loading speed while maintaining its quality.

10. Cache Data to Optimise for Offline Mode

Ask the mobile app development services provider for data caching, as it allows users to use the app without an internet connection. Data caching enables the app to store and retrieve previous content locally. Users can access this content even if they are offline. It leads to better engagement and user experience.

To rephrase in different words while not changing the original meaning of the text, shortening the sentences while still maintaining coherence:

Additionally, server burden may be reduced through data caching since fewer requests are sent to it thus leading to savings on bandwidth. Asking your mobile app development services provider to integrate efficient data caching methods is a preventative measure taken so as to guarantee that your application stays trustworthy, swift and user-focused at all times. In this manner, customer interaction is enhanced and trustworthiness established as well because it will work fine irrespective of their networking state.

11. Optimise Screen Size

This is the Android problem. There are hundreds of Android devices available with different screen sizes and resolutions. It is challenging for Android app developers to test the app for various screens. Developers can customise the layout and functionalities of the app to ensure that it fits different screen sizes.

12. Update the App Regularly

Regularly update the app to add fresh features and functionalities and fix bugs and other vulnerabilities. In short, you can keep your users engaged and interested with regular app updates. Also, the app stays relevant and valuable by regularly introducing new features and functionalities.

Conclusion

You must ensure the app performs optimally to retain users and beat the competition. User expectations and technologies are evolving with time, and you must keep your app relevant to meet their requirements. You must adopt the best mobile performance optimization techniques for an engaging user experience.

By optimising the app's performance, you can enhance the app's usability and increase the number of downloads and actions.
