Hi Jim, re: "And newer silicon will defeat the [heat/power] problems." No, not necessarily. It's far from conclusive that the portion of the design in question was the primary contributor to heat/power. It's just a piece of the total. Handsets aren't exactly efficient at radiating heat away, especially when you have 98.6 degree body parts covering parts of it while talking. The heat accumulates in the outer case, which isn't exactly an efficient radiator. Instantaneous power drain that is near the design maximums may be quite acceptably low, but let that accumulate for 10-20-30 minutes under use, and the shell gets warm. I really don't see where observations of detecting warmth via your hands, when there are so many time-variable operating parameters hidden from observation, and which accumulate, can allow any meaningful conclusions. re: "Nobody said it explicitly, but I get the sense that all-IP mobile networks are less power-efficient than their predecessors." I'm not sure that's a properly supportable conclusion. There are way too many unobservable variables being lumped into a single black box observation, and so many different ways you could actually measure power efficiency, and so many large differences in the functionality of the end user devices. How would you even make an end-to-end apples to apples comparison of power efficiency of say 3G vs 2G? Would it even be fair to just compare the handsets? There have been network-wide changes and efficiency improvements, but there also has been a huge increase in users and usage. If you had a stripped down 3G handset that did no more than basic IP phone functions compared to a 2G handset where all else is equal as near as possible, I have my doubts that 3G handset would lose a power shoot-out of measured watts vs time. There have been across-the-board improvements in every power-drawing component, from the displays, to all chips and even in battery technology. PS all my 2G handsets I've had, got quite warm to hot, progressively during any extended phone call. There's no IP there. Well I've probably rambled on enough for now ;o)
