I think that's correct. The power cost of processing
3G CDMA is
still higher than
GSM, but the amount of power this uses in either
mode has dropped to the point where it doesn't matter so much. And
the efficiency of RF power amplifiers seems to actually be worse for
EDGE than for
3G (the vendors of power amplifiers seem proud if they
can approach 30% efficiency for
EDGE, UMTS amplifiers are usually over
40%; regular
GSM is very good, though), so there may be very little
net difference between the two. The battery in my Motorola V9
actually seems to last a little longer on a strong-signal
3G network
than it does on a strong-signal
EDGE network.
I hence agree that if the battery turns out not to last as long
in a
3G iPhone this is most likely only because you can move a whole
lot more data with a
3G phone. That's a problem I'd like to have.
I also note that the rumor posted here had the
3G iPhone being
tested in "several countries". If the "several countries" include
both the USA and almost anywhere else, and if there is only one
3G iPhone model, then Apple will have done something that most of
their competitors haven't managed. When I was looking the only
phones I found which include
3G support for both the US/AT&T and
for Europe/Asia in the same phone were a couple of HTC phones
which don't do well in reviews.
I want a phone with global
3G support, I only bought the V9 when
I failed to find a phone I could live with with that support. If
Apple does support this I'll seriously think about buying.
