Yup, but I leave mine on as the only thing I got synced for notifications with it is my gmail account and that's the account I get pretty important emails. My junk email (Yahoo) isn't synced for notifications, too much spam:frown:It depends on your notification needs. If you don't mind manually checking your email accounts and remember to manually sync your contacts and calendar every time you make a change, then you could probably save some battery by turning off automatic syncing.
