Is your app consuming a lot of memory and battery or experiencing frequent crashes?

-An app might spin up too many threads and soak up memory resources or run on a system that has too many apps open.

- The OS might be unstable, the user might not download the latest version, or the OS might get updated while the app has not got updated. Also, the APIs might have a performance limitation for a particular app.

-The need for testing is evident, but getting sufficient coverage, particularly with the plethora of Android versions and devices, can be demanding.

-As apps have growing to depend on network access, either for third-party or data services, network management has grown as a source of trouble.

-Unexpected API change, a memory problem that avoided the previous detection, or a network condition that ends connectivity or even slows data speeds during the transmission of large files like images or video can also be a source of the problem.

How it hampers user experience?

-The app might suddenly crash when the user is using it, and it can be very frustrating at times.

-Some apps might take ages to process, and hence, users uninstall them because, eventually, nobody likes to use slow apps.

-There are times when the app might download unnecessary data, might run in the background or keep high-demand system resources when it doesn’t need to, and this leads to excessive battery drainage.

-Some apps get designed in a problematic and not a user-friendly way. This can annoy the users, and they might switch to a better app.

-Users face problems related to navigation and flow.

Some solutions on how to work on memory optimisation and battery usage-

-Look for ways to reduce and optimise battery-intensive operations.

-There are also internal mechanisms in the platform to help conserve battery life apart from APIs. Testing and troubleshooting, adapting your app to doze, applying background or management restrictions might also help.

-To optimise the memory usage, Android tries to share some framework resources or common classes in memory across processes.

One should always watch out for dirty memory, as most of the memory in a running application is dirty memory.

-While working with recycled views, if you are using Firebase with it, use Firebase Paging Adapter.

-There are tools for Android, including Profile GPU Rendering and Battery Historian, to help you identify areas that you can optimize for better battery life.
