When an Android phone is running low on memory, it will try to free up resources by closing applications not in use. However, it turns out that there are a number of poor behaving background applications and services out there that simply restart when the OS closes them. This actually makes the situation worse! Android closed the application to regain memory but it restarts and begins consuming just as much memory as before. Even worse, starting and stopping applications consumes CPU time so not only have we not freed up any memory, we are using a lot of unnecessary CPU resources.
