How to reduce mobile app size and phone battery consumption?

A modern mobile app should be simple, intuitive and user-friendly. These are prerequisites, but in 2023 they are not enough. When was the last time you deleted a recently installed app from your mobile? Were you not interested in the app itself or were there other reasons? Maybe it was taking up too much space in your phone memory or consuming unnecessary traffic? Or maybe it was draining your phone battery faster?
When an app affects your phone's performance and efficiency, it's quickly removed. The lifespan of a typical mobile app is 6 days!
Developing a mobile app that uses minimal data and RAM without sacrificing the phone's features and performance requires careful development and additional testing. And, of course, such a product costs more.

Mobile applications from Cordus Technologies: small and efficient
A small mobile application, of course, takes up less space on the user's device. It is easier and faster to install. The smaller size also reduces the network bandwidth used to download and update the app. This is especially important for users with limited data plans.
Cordus Technologies Inc. creates mobile applications that holistically address issues related to battery consumption and network speed. Minimizing size is a pressing concern when developing a new application and should be set by the customer at the outset of the project. Cordus Technologies programmers develop small applications that use less traffic. What rules should be followed when developing a small mobile application if one of the terms of reference is to reduce phone battery consumption?
Optimize runtime
Code minimization, delayed loading or automatic unloading of background processes help to reduce the size of the application and increase its performance. Code minimization allows you to remove unnecessary characters without changing functionality. Lazy loading loads components only when they are needed (e.g., when scrolling); and automatic unloading completes all processes that are not actively used.

Reduce the number of queries
During development, you need to reduce the number of requests the application will send to the server. To minimize this figure, Cordus Technologies uses caching techniques.
Code optimization
When optimizing, unnecessary lines and dead code are removed. Poorly written code requires more processing power than necessary and often leads to increased memory usage. Increases not only load time, but also battery consumption. Cordus Tech developers optimize code for Android and iOS platforms, checking it against a coding standard such as Common Weakness Enumeration (CWE).

Minimizing Image Sizing
High-resolution images can affect the size of a mobile app. To reduce memory consumption, it's best to use low-resolution images in the following formats: JPEG, PNG, and WebP.
Minimizing Animations
When animating applications, high quality graphics are usually used, which requires a lot of processing power, which wastes battery power faster and also increases the file size. You need to reduce the quality of the graphics.
File Compression
Compressing large files before sending them over a network connection can also help reduce the amount of data used and speed up download times.

Merging resources
You can try to merge several resources into one file. This should reduce the number of requests and the size of the application.
Reduce your dependency on libraries
Check the plug-in libraries. Many applications don't use most of the libraries and additional resources, while increasing the weight of the product and not the user.
Cloud services
Use cloud services such as Amazon Web Services (AWS) to store and access your data. This will reduce the size of your application and help improve performance. Cloud storage of locally large files and data sets associated with a mobile app helps users who are away from home or don't have Wi-Fi access to use the app they are developing while reducing its overall size.
So
Developing a mobile app is a necessary step for any business that wants to stay competitive today. The mobile app market continues to grow. Now it's not just the idea that matters, but also the size of the app and optimizing battery consumption.
Keep in mind that the cost of developing an app with initially optimizing the size and performance of your app can vary depending on its complexity, from a few hundred dollars for a simple app to several thousand dollars for a more complex app.
In conclusion, reducing the size and battery consumption of a mobile app is beneficial to both the user and the developer. It helps simplify and speed up app installation and increases user engagement.
