Integrating energy-efficient design principles from the development phase can significantly reduce power usage. Prioritizing features that minimize screen-on time, leveraging efficient data synchronization methods, and adopting low-power modes for sensors can further enhance battery life. Additionally, user education on optimizing app settings for power conservation can complement these technical improvements, ensuring a holistic approach to energy efficiency.

To optimize code in mobile app development, employ techniques like minimizing network requests, utilizing lazy loading for resources, implementing code splitting for faster initial load times, optimizing image sizes, reducing unnecessary animations, employing background tasks judiciously, and regularly profiling and refactoring code for improved efficiency and performance.

After energy profiling, the primary goal is to fix the issue that is causing battery drain. Most of the time these issues can be fixed by optimizing the code or adopting strategies for various use cases. In the code optimization part, what works for me is to look just at the code that is causing the issue and try to work on its constraints (i.e. complexities). If you're using an algorithm try to fit it into your use case, i.e. make it constraints bound to serve for your tasks only and nothing extra. Mostly battery drain is caused by the applications running in the background, which should be reduced to processing smaller tasks and using fewer hardware resources (such as Bluetooth, GPS, etc.).

Code optimisation means removing unnecessary code or service calls, which will also help to achieve battery optimization. keeping heavy processing on the server side.

As a Flutter developer with 4 years of experience, I once worked on a fitness app that suffered from excessive battery drain.

As a Flutter developer with 4 years of experience, I improved an e-commerce app's battery efficiency by integrating power-saving APIs. These APIs allowed the app to adjust its behavior based on the device's battery level and power-saving settings. When the battery was low or power-saving mode was activated, the app reduced background activities and resource-intensive tasks. This approach significantly extended battery life, enhancing user satisfaction. This experience emphasized the importance of utilizing power-saving APIs to create apps that are both functional and energy-efficient.

Developers can now use special power-saving APIs to manage an app's battery usage better. These APIs let your app change its behavior based on the device's battery level or power-saving settings. By using these APIs, your app can reduce its power consumption when the battery is low or when a user activates a power-saving mode. This helps your app save energy and extend the device's battery life for the user.

As Android developers, ensuring our apps are power-efficient is crucial. With WorkManager, we can define precise constraints for background jobs, enhancing battery conservation. Some key constraints include managing battery levels to run tasks when sufficiently charged, scheduling jobs during device idle states, specifying network types for task execution, and verifying storage availability before performing tasks. The WorkManager API not only improves user experience but also optimizes overall app performance by efficiently managing background tasks and enhancing power usage.
