I was curious to see if there would be a difference between the computer and wall too, right now I have mine plugged into the wall, so ill post my time if I am awake when it finishes
UPDATE: it has been a little over a hour since mine has been on the wall charger and I just checked it and it appears to be a little more than 75% full....idk if that is accurate or not, but if it is that is AMAZINGLY quick
USB ports compete for current with other accessories on the computer and some are low power ports anyway. The AC charger gets full current to the iPhone/Pod all the time.
I have a DICE iPod interface for the stereo in my Audi A3 and it plays iPhone music just fine, the steering wheel controls work to change tracks and it charges -- all after dismissing the "not compatible" warning when I plug it in.
It will not, however, put phone audio through the stereo.
Okay, I'm done. I charged off my MacBook Pro while using the computer to surf the web and check email constantly. I also woke & unlocked the phone 3-4 times to make adjustments in Settings.
The first charge time seems to vary on units and I suspect some had more initial charge (one of ours charged in about an hour the other took about 8 hours on the first charge). The last bit of charging seems to take forever.
I don't mind the length of time to charge because the battery life is really impressive.
I went to the apple store and looked for a longer cable so I could use the phone while talking, even bought a car charger kit that seemed to have a longer cable. In the end the cable was almost as long as the original one.
Why did Apple make the cord so short compared to many other phone cords? Is there a safety reason? The store employees said I could always use an extension USB cable, but I'm wondering if this is a safe idea.
What do other people do so they can charge and talk?
