So when we have to diagnose the battery drain that means first we have to think about the battery usage while we are creating our application. So there we have to use like we have to avoid to consume the high battery like we have to consider the network usage we have to continuous we can say a continuous monitor the network activity and optimize it other thing the background services so we have to identify the background services it may be running excessively like we need some we have to consider that the second thing is we in android android profiler is there in android studio so with the help of profiler we monitor the battery usage and identify which which feature is taking more battery usage and we can say optimize like we have to when the operation is network operation so that time instead of one operation we have to give the batch of network request so it will we will give the combine network request optimize the data transfer so we have to consider the optimization purpose also and we have to use foreground services job scheduler the thing is work manager and we have instead of that we have to also check the real device testing we can say that so one android profiler is good option for that
