syncing on app on the background

[Power_Manage]

Hi 

I have some instances where the user has updates waiting to sync , then he quits hes phone , and the data does not sync to the db until he opens hes app again and syncs. 
is there a way to have the phone upload the updates to the db in the background ? 

or any other creative solution will help . somethimes users does have have good internet or phone is old so syncing might take time
