I found a solution to charging my iPhone while my Mac Mini is sleeping overnight. I didn't want to leave my computer on all night just to charge my iPhone, and didn't want to switch between the computer and wall charger every day. Usually, when you put your Mac to sleep, it cuts power to the USB ports, so your iPhone won't charge. To solve this, I ordered the "iPod Dock Connector to Firewire and USB 2.0" from the Apple store. With this cable, you can use the USB end to sync with your computer, and use the Firewire end to charge the phone overnight. Both ends stay connected to their respective ports all the time. This works because the Firewire ports still provide power when your Mac is sleeping, unlike USB. I currently have it plugged into a powered Firewire hub, but I've also tested it with a Apple 23" display and MacBook Pro.

Yep, the USB ports on a Mac don't supply power when the Mac is sleeping; however, the FireWire ports do.

Another option would be to have the computer "wake from sleep" for an hour or two (not sure how long charging takes) and then sleep itself again. You can do this vis System Preferences --> Energy Saver --> Schedule...

Dan - I haven't tested this on Intel Macs but PPC based Macs do NOT supply power to the FireWire ports when the computer is asleep. This became an issue when Apple shipped generation 3 iPods. Gen 1 and 2 iPods used standard FW cables but with the switch to the proprietary port, when the computer went to sleep the iPod power drained - USB or FW port.

My PowerBook G4 would charge my iPod while asleep. That was a PowerPC computer and a 3G iPod. The caveat, and a fairly obvious one, was that the computer had to be plugged in to provide the power; if you were running on battery power, no iPod charging while asleep. Otherwise, when plugged in, the iPod would charge just fine over FireWire.

I think kirkmc was asking was not a confirmation of the hint issue, but rather could you just plug your USB cable into an external powered USB hub and it would still be charged when the Mac was asleep. If so, your iPhone would still sync and interact with the Mac as if it was plugged in directly, and also charge when asleep without having to buy an additional cable.

I originally tried plugging the iPhone USB cable into a powered USB hub, and it looks like the hub stops supplying power when the computer it's connected to shuts down or sleeps. Apparently you can modify a USB hub to supply power even when the computer is off or sleeping though.

No - my 5G iPod will not charge when hooked only to a (powered) USB hub.

I can confirm that just using a powered USB hub is not enough to get your iPhone to charge when your computer is asleep. I bought a powered hub to do exactly this with my iMac and was very surprised when it didn't work.

The Firewire/USB -combo-cable is essential when using any of the bigger iPods or iPhone as mere USB doesn't provide enough power to charge the unit AND transfer songs. If you connect the device to a computer when it's low on battery and immediately start loading it full of songs the unit might shutdown during the process. This shutdown can be "fatal" to the device.

My 800mhz G4 iBook and my Core Duo Macbook doesn't cut power to the USB ports when the computer is sleeping. Only when fully shut down.

I recently bought a Targus 7 port USB powered hub that has 2 ports that stay powered regardless of computer condition (On, Sleep, Off) and can be used to charge or run any USB device.

The Targus hub with the "always on" ports do not charge an iPhone by itself.

Now I am very confused, again!

The USB ports on my 2.33 GHz Core 2 Duo MacBook Pro do provide power when sleeping. I charge my Treo 650 every night that way.

Apple clearly states not to plug both ends into a computer at the same time. The Firewire end is supposed to be plugged into an AC power adaptor.

This article is from 2003, when iPods still used Firewire for Data transfers. It's not valid anymore. Since the firewire port is used only for power in the ipods the computer effectively becomes a charger in that situation.

The article on Apple.com mentioned above was updated this year "Last Modified on: August 28, 2007". As a side not it appears that only the 5G iPods and the nanos cannot be sync'd with Firewire.
