Disagree. I read plenty of articles outlining how the newer 3G chips were a lot more power efficient. At least one of those was a technical review (by someone like ArsTechnica or Anandtech, can't remember who).
Don't get me started on today's tech article writing
You're probably talking about
this AnandTech article that bent over backwards to come up with ways to say that WiFi was better than 3G. (Of course, today's more experienced consumers would laugh at the idea of a 2G-only smartphone.)
Just as with multitouch patent news, everyone else quoted them without doing any further investigation or thinking on their own. Yet it had no real scientific testing, no metering first of the power draw differences in screen backlighting, etc.
First off, they picked a 3G phone that was widely known to be a battery hog, partly because it had HSDPA support (the iPhone only had EDGE). Of course, it was over ten times faster on the internet than the iPhone.
That 3G phone came with two batteries, a 900 mAh and an extended 1200 mAh. It's clear they used the lower power one, against the iPhone with its 1400 mAh battery. It was extremely disingenous of them to not provide all that information.
So when they concluded that 3G used 23% more battery and 'woe is us' and all that BS, well why not just slap in the included extended battery which gives 133% longer life and more than makes up for the difference?
Proving that the iPhone could've done fine with 3G didn't fit their agenda, which was to excuse Apple even though every other smartphone on the planet had 3G.
The fact is, leaving out 3G lowered the price by
up to $100 per phone, and that, along with being able to get carriers to offer a cheaper data plan, was FAR more important than any battery considerations.
So it goes.
