iPhone 4 charges SO slow !

I just got the iPhone 4 yesterday after lining up at 5am in Canada.
Great phone, i LOVE it! HUGE improvement. While the battery itself is great, the charging time is SO slow! at least for me anyways.. anyone else have this problem?

I've been charging for 2 hours now, and it's only at 62%
My 3G would be fully charged in an hour or so..

(PS.. I am charging through USB - I understand outlets will help improve, but I always charge through USB anyways)

I think it takes like 4 hours via USB, and just a little over 2 hours from the outlet.

Battery capacity is larger so it's only logical it would.

Mine isn't slow. It is about the same as my 3GS. No complaints here...

I havent timed it or anything but mine takes approximately 3 hours to charge from 0 to 100%. It doesn't really matter to me. I can get 1.5 - 2 days use out of my phone which is what's most important.

I thought I remember reading that the battery is the same in the 3GS and the 4, but the 4 seems a little improved due to software using less battery or something?

My phone charges pretty fast btw.

Larger battery and optimized processing. "the battery life seems markedly improved in the iPhone 4, and why not? It's got a much larger battery coupled with that iPad-powering A4, which has already shown that it can sip rather than gulp power."

Yes mine is very slow to charge too. Being a bigger battery, it makes sense. My 3G can charge SUPER fast.

I charged mine with my 10W iPad charger the other day and it seemed to go much faster. Not sure if this is really true or my imagination though. I'll leave it to someone else with more time than me to confirm. Obviouly, the iPhone charging circuitry will limit the current to what the the phone can handle, whatever that limit is.
