Before loading slowly, no one will consider how good the application's performance is.
If this situation occurs, a person may consider looking for alternatives. Especially now there are various solutions to choose from: as of the first quarter of 2021, there are approximately 5.7 million applications in Google Play and Apple App Store. In fact, if the loading time is too long, 70% of users will leave the application.
In addition, dissatisfied users tend to express their opinions through ratings, which directly affects the download volume of the application. An average rating from 2 to 4 stars can increase the conversion rate of the app store by 680%!
Therefore, it is difficult to improve app performance - its ability to load on various events.
What makes applications effective?
Due to the fact that mobile application performance is more comprehensive than application speed, you need to track more parameters:
• Fast application loading time - up to 2 seconds; • The application is compatible with the device it is using (system requirements, screen resolution, etc.); • Reasonable memory and battery consumption; • UI and UX make applications easy to navigate and use; • In the background state, the app will not lose user data and progress; • It seamlessly integrates with required third-party applications and device services such as cameras, Bluetooth, calendars, etc.
What causes performance issues in mobile applications?
){kind=link}
Common reasons why your application may be far from optimized include connecting to the server side, application main threads, and interfaces.
Server side
Obtain a large amount of useless and heavy data from the server, frequent HTTP request calls API latency, errors, and data compression.
Main thread
Perform heavy operations on the main thread of the application Database operations on the main thread of the application, as well as inaccurate design of databases and data retrieval techniques.
Interface
Incorrect technique for rendering shadows on interface elements.
In short, these are the most common reasons for application performance issues or slow application operation. Usually, each solution has a unique situation.
Mobile Application Performance Optimization Checklist
Below you will find a series of methods that can improve app performance and enhance the user experience.
- Effective cache data
In order to speed up the application, it is necessary to define files and calculations that can be cached. Storing resources and operations in the device's hard drive ensures instant access to application data and eliminates performance issues in the event of network interruption.
Define cycles for appropriate caching. For example, it is reasonable to cache the product catalog before the administrator updates it the next time, while the user profile should be cached for a single user session.
At the same time, it is important to maintain a balance between data caching and data loading to avoid displaying outdated data to users. Similarly, when the space for storing information is limited, not all content should be cached. - Optimize images
It seems that the larger the image, the better for the user. In fact, using images larger than those displayed on the screen is meaningless. Optimized images and graphic elements help eliminate latency when using applications and shorten the loading time of content on the screen.
