First things first, I am not posting this for the sake of an argument. I'm only posting this for a discussion to clear whether if the ipod and iphone batteries are the same or diff.
i have taken the liberty to do some research on this. Some data has been obtained from this website:
http://www.ipodbatteryfaq.com/ipodbatteryandpower.htmlall ipod and iphone batteries are 3.7V and will charge on 100-240V even down to the first gen ipods...
i bought a ipod charger for my nano before i got my iphone.. the charger is both the same..
its written iPod USB Power Adapter. the input and output are all the same... same ampere, and voltage which is 5V and 1A
Even if u wanna buy a new power adapter from Apple Store its universal. Apple designed it to be universal. For those of you who don't believe, just take a look at your "Apple iPhone Power Adapter". Read the bottom label and see what it says.
If its an Apple USB power adapter then I believe its fine.
You only have to worry about some car chargers and those 3rd party adapters. Reason being their voltage and ampere might differ therefore making it only charge your ipod and not your iphone.
That is just my own 2 cents and my research around. No punt intended to anyone out there. Cause I dun believe that there is any differences in the power adapter.
If anyone can present me with proof and schematics that the battery for the ipod and iphone are different then i will change my beliefs.
