I recently upgraded from a Motorola Atrix 2 to the Samsung S3. I have a question which I had difficulty locating answer. My question is about the Sync option that can be disabled: I am experiencing much shorter battery life as my Atrix 2 doing the exact same daily tasks. In fact, my daily pattern is extremely consistent, and my Atrix 2 could make it all day, whereas the Galaxy 3 was less than 10% by 2:00 PM. My question is if I disable Sync, will my Apps still update when I open them? For example, right now I have Sync enabled and have a Corporate Exchange account added. So I get notified of any new email. If I turn off Sync, I know I will not receive notification of new email, but will I receive new email when I open the App itself, or will nothing ever come down to the phone when Sync is off, even when I physically open the App? The same applies to my Gmail accounts. I may have other questions in the future as well, and I appreciate having this forum to post these questions!
