First, Apple didn't do both...There were reports that even with every new features turned of on iPhone 3G(bluetooth wifi 3g etc.), it still gets less life on daily usage.
What do you mean? It's kind of hard to deny that they didn't add new HSDPA/EDGE baseband hardware and reduced the battery size.
Remember the quote for EDGE is 10 hours of talk time. That's almost 50% more talk time on EDGE using a smaller battery versus the iPhone 1st gen phone. That's quite definitive to me that the new baseband hardware is using a more advanced CMOS process than the 1st gen hardware.

So, most likely, some networking related chipsets (bluetooth, wifi, and 3g/edge) got more efficient, but the phone (CPU, graphics and OS) did not.
Sure, a lot of parts didn't change, importantly, the CPU and GPU, but many of the other components are relatively small parts of the power picture. Some of those parts did change. The biggest change was iPhone OS X 2.0. It was kind of buggy and unoptimized, but Apple is slowly taking care of that.
