Perhaps we shouldn’t be surprised that 3G uses so much power. Is it because you must contact a faraway base station rather than simply using the nearest access point – and cities they are typically very near? Is the protocol itself power hungry? Are 4G or WiMax any better? How much of the energy usage is due to the complexity of cellular protocols—supposedly 2G is lower usage than 3G? I’d be interested in numbers from those who have done the analysis.
If you multiple this by a hundreds of millions of phones and another billion devices such medical monitoring devices then we have a huge unnecessary energy footprint in order to give each entity its own billable path rather than allowing more efficient sharing of bit paths. Same with “broadband”.
Simply using the nearest Wi-Fi access point makes a lot more sense. But we still need to do work – I don’t think that 802.11 puts much emphasis on managing power levels (does it?).
Just as important are the post-ICANN protocols to address the problems with today’s protocols which are dependent upon those (billable) paths and on the DNS for faux stability.

The old iPhone had basically the same problem. If you leave the phone in 3G mode power consumption is quite heavy. If you leave the phone in non-3G mode but with WiFi and Bluetooth enabled, I find on either generation phone I can go most of the day and not go below 60% battery. I have always berated Apple for stealing the battery on general principles. But if anything I find the new iPhone 3GS to be better on the battery again as long as you keep it out of 3G mode unless you need it.

Before you even think about rushing out to buy the new iPhone, you might want to read an interesting story about continuing negative reactions to the iPhone 3GS' battery life ( http://www.latimes.com/business/la-fi-iphone3-2009jul03,0,2546606.story ). Of course, all smartphones are power hungry, and we use these Internet-enabled phones for so much more than just talking. But the iPhone is a particularly egregious case since the battery is sealed inside and not considered to be a "user replaceable" item. My G1 phone also sucks a lot of juice, but I can pop in an extra charged battery anytime, and I have an extended duration battery (bigger is better!) to use in there as well. With the iPhone, since battery life sucks, you're really stuck. There are, however, some comparatively ugly workarounds. One person responding just now to a tweet of mine on this topic says that he uses a solar charger. I guess that's OK if you don't leave the iPhone itself out in direct sun, and don't keep smashing your head into the solar array (OK, so the solar array isn't really that big ...) A more practical way to deal with the problem may be something like this external battery pack ( http://www.radioshack.com/product/index.jsp?productId=2767656 -- only $20 on sale -- 50% discount -- at Radio Shack through July 11). You can always duct tape it to your iPhone. Won't that be pretty? More generally, the whole concept of sealed-in batteries in Apple devices strikes me as the epitome of "those suckers will buy anything with our name on it -- boot to the head!" consumer relations. But hey, whatever turns you on. --Lauren-- Lauren Weinstein lauren () vortex com Tel: +1 (818) 225-2800 http://www.pfir.org/lauren Co-Founder, PFIR - People For Internet Responsibility - http://www.pfir.org Co-Founder, NNSquad - Network Neutrality Squad - http://www.nnsquad.org Founder, GCTIP - Global Coalition for Transparent Internet Performance - http://www.gctip.org Founder, PRIVACY Forum - http://www.vortex.com Member, ACM Committee on Computers and Public Policy Lauren's Blog: http://lauren.vortex.com Twitter: https://twitter.com/laurenweinstein ------------------------------------------- Archives: https://www.listbox.com/member/archive/247/=now RSS Feed: https://www.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com ------------------------------------------- Archives: https://www.listbox.com/member/archive/247/=now RSS Feed: https://www.listbox.com/member/archive/rss/247/ Powered by Listbox: http://www.listbox.com
