USB Power Adapter + Battery
ok...i know im asking questions all over the place today...but i had the day off so its all coming out at once :)

i was wondering if there is any significant difference in the speed at which charging takes place when using the USB Power Adapter over charging via the laptop...

the only reason i ask this is because i dont have the adapter...& this other guy i once met who had an iphone 4 was complaining about how often he needed to charge it said his iphone charges in about 20 mins...which mine does not :\

so incase someone here can confirm faster charging with the adapter...then i might buy one...otherwise i dont think i really need it...

on a side battery seems to drain pretty fast...maybe this is regular paranoia for someone cominf from a dumber phone...but yesterday i lost 3 percent charge while it was on charge! i really dont know how that happens?!

It's a no - brainer. A good USB power adapter (I use Belkin) will charge your iPhone, iPods, etc, in about half the time it takes using the ports on your Mac. I like the Belkin model so much that I bought two; one for home the other for the office. If there's a Target store near by, check them out. Mine were $24.95 each - on sale.

hmmm...i was actually referring to the apple power adapter actually

but either im interested in knowing...why is it a no-brainer? i dont know about the belkin...but if im not mistaken the one by apple provided 5V which is the same as a USB i missing something?

Hmmm...using the word "actually" twice in the same sentence. One of my pet peeves are folks that use the word "actually" too often & inappropriately.;)

Yes...WE are missing something. You're not explaining your situation/question in enough detail. What sort of charger are you referring to...other than charging the battery while in your laptop?

rohan 02-07-2011 04:39 PM disctacted "actually" and lost track of what i had written before :)

what i was talking about is this:
Apple USB Power Adapter - Apple Store (U.S.)
which is the one that ships with the iphone as far as i know

what you a probably referring to is this:
Belkin Rotating Charger 2.1 amp + ChargeSync F8Z630tt04

which would explain a lot since it specifies its a 2.1 amp charger
which is double of what the apple adapter is supposed to be...hence yours charges in half the time...

Aah...that helps.:)

I think that both "chscag" and myself thought that you were talking about charging your iPhone in these two ways:

1. Charging it with an external charger (like both you linked in post #5).

2. Charging your iPhone from one of the USB ports on a Macintosh computer.

I'm thinking that what "chscag" meant by a "no-brainer" that charging your iPhones battery via a separate "plug-in" charger is almost always better/faster than charging from a computers USB port...since the USB port on a computer generally is not that powerful.

BOTH of the devices you mentioned...are external (external to a computers USB port) devices for charging. So either one will be faster than a laptops USB port.

So charging your iPhone via an external charger (either one of the two your linked) will be faster than using one of the USB ports on a laptop.

well...i don't think the 1 amp version would be significantly faster...since it doesn't seem to have any technical matter what is fed in...output at the usb port is still the same 1 amp & 5V

the belkin one however will make a difference
