Q: Only sync via wifi when plugged to mains?

I recently upgraded to a new EC mac from SL, and found I can no longer set itunes to sync automatically whenever I'm in range over wifi.

 

When did they decide this was a good idea? You might as well just plug in the cable!

 

If I can sync by clicking over wifi when not plugged to mains and sync by cable automatically why not automatically over wifi? 

 

OK, some people will be downloading books and music and all sorts, but most of us just want to keep diaries up to date.

 

It's the whole point of having a mac and an iphone - no?

 

Does anyone know a workaround?

 

Tom

    Wi-Fi uses battery power and if iPhone sleeps, Wi-Fi is switched off to conserve battery.

    That's why you connect to a main (Wi-Fi will then be kept alive) for syncing.

    Automatic iTunes wifi synchronizing has never worked when the iPhone or iPad is running on battery power. See Sync your iPhone, iPad, or iPod touch with iTunes using Wi-Fi - Apple Support  Automatic wifi sync has always only ever worked when the computer is on and iTunes open, and the iDevice is on the same wifi network and plugged in. The simple reason is that the wifi radio is powered off when the device is running in battery and goes into screen sleep mode. So an automatic sync is likely to get interrupted and data possibly corrupted.

     

    You can manually force a wifi sync when on battery power, but it has never supported aotuomatic sync over wifi when on battery power.

    Err - yes indeed, the Mac has always had to be on mains power, but the message on my phone was that the iPhone had to be plugged in now. And this was confirmed by the girl at Apple.

     

    you never had to ug the phone into the mains before. It defeats the whole point.

    You or they are mistaken. I've been using wifi sync since it was first introduced. And automatic sync over wifi has never been supported with any iphone, iPad or iPod touch unless the device was plugged in.   As I said, the wifi radio is powered off when the iDevice is running on battery and enters sleep mode, and idevices have always behaved that way.

     

    The only way to have iTunes wifi sync work automatically has been when the iDevice is plugged in, thus keeping the wifi radio active.

     

    It's the exact same reason why automatic iCloud backups only occur when the iDevice is plugged in.
