I recently downloaded a program that I need to run on auto-sync. Within the program, it has an option of setting the interval to only once an hour, which I chose. Unfortunately, this only works with auto-sync on. I have always left auto-sync off, due to battery drain. My question is, if I set auto-sync as ON, but disable it for every program that shows up in my sync list (gmail, mybackup, twitter, facebook, etc.) and only have that program as active, will it still drain my battery? Or, hopefully, will it only check for auto-syncing once every hour since that's the only program it should be checking for?
