Hi! I've never seen this before iOS 6 (or on a prior iPhone model) but on my iPhone 5, I've noticed that when my MacBook Pro is closed and sleeping, and I've plugged the iPhone into it to charge, the sync indicator goes off on the iPhone. I have no idea what it's synchronizing or how, as the computer's sleeping. Any ideas? I couldn't Google up an answer. Thanks for your assistance!
iPhone 5, iOS 6
If you own a newer macbook and have Moutain Lion on there is a feature called power nap that allows stuff like this to happen while the computer is asleep. It is a feature. Nothing wrong at all.
I'm running Lion. Does that make a difference?
The iPhone will backup data when plugged in to a power source and connected to WiFi
Even on Lion (10.7.5), when the computer is sleeping?
I believe Lion does it as well on the newer macbooks.
And I don't have access to anything Power-Nap-related under Energy Saver. Could it be something else?
As long as the iPhone is connected to a power source (ie your macbook) and a WiFi connection it will backup, at least to iCloud anyway
There is not settings as far as I know of for powernap. It is an internal firmware that does it. If you don't want that to happen then shut the computer down completely instead of just closing the lid.
My iCloud Backup has been switched to off for always.
I found settings for it here: http://support.apple.com/kb/HT5394, but my Energy Saver preferences don't have it, possibly because I'm not running Mountain Lion.
