I, and others, have experienced a similar situation @Rubyconna … later posts within threads here and here indicate observations which I believe are identical to yours. (All are running 0.4.4 … this does not resolve the sporadic disconnection issue you highlight).
I have not seen any definitive response from Particle confirming this is a known issue (if it indeed is), if it is expected behavior that needs to be addressed within application code, and/or if there are any recommendations to maintain a persistent cloud connection.
