And is it safe to turn off ? It keeps showing up on my top 3 apps using battery.
Well, Samsung link service allows you to transfer files remotely from your device to PC, it is like Google Drive, Dropbox type cloud storage and retrieval technique. But the bad thing about this application is it doesn't offer you cloud storage i.e. you have to link your drop box or sugarsync account, and I am sure you might be having google Drive or Dropbox application for this then I would say there is no use of it, turn it off as it consumes the battery most.
