Nokia just added this feature to their new smartphones but their main improvement is a better camera. I think wireless charging would not be cost or space effective but it could increase reliability by eliminating broken connectors.
Peter, within one foot? Not likely. Even the wireless EV charger that was demo'd at CES two years ago relied on the undercarriage receiver and the floor mat transmitter being within a few inches of each other.
For wireless charging of mobile devices, you're still looking at placing your device on a charging mat with fairly precise alignment to a coil within the mat -- exactly like today's wireless charging mats require. The gap between transmitter & receiver coils is a small fraction of an inch.
In any case, it seems crazy that Intel would think of wireless charging as some sort of strategic weapon. There are already a variety of products on the market, the WPC has it's Qi standard and newer revs in the works, CEA is starting another standards effort, and now Intel wants to do it's own thing too.
I admit it would be cool if an Intel-powered Ultrabook could wirelessly charge a phone. But if that only applies to Intel-powered phones, then it's a useless feature for 99.9% of mobile phone users and will unnecessarily add cost to the Ultrabook.
The advantage of being within one foot of wireless charging source is that you don't have to plug and unplug a charger connection into the phone.
That's about it.
But cranking/shaking may not be such an "awesome" prospect if the craking to battery life ratio is relatively low, say 5:1.
How does 12 minutes of cranking/shaking for 1 hour of phone life appeal?
So far wireless charging is mostly a sales thing. Other companies already have wireless charging like texas instruments. But all the products i have seen only work if you are less than 1 foot away from it? What is the point in that?
I would like to see a mechanical charge cell phone. So that all i have to do to charge my cell is give a cranks to a small wheel on it. Or maybe shake it like you can do with some flashlights.
Because i get tired of my cell going dead and i am not by any power supply. I would love to go wait one minute i shake my cell phone and it is fully powered up again. Now that would be awesome.
I agree, and wireless charging is largely, I feel, a gimmick (like siri). Is it really so much effort to plug in your phone?
I wonder if the day will come when people are less and less receptive to 'innovative' new technologies.
I do not think this is such big an issue to be honest. Non-Intel consortia can well develop their own wireless charging standard and bring it to the market fairly quickly. Efficiency is not such a big thing provided it's within 20% or so of Intel's. If Intel are really thinking of using this as a strategic weapon against their competitors in the mobile market, then God help Intel :-)
I fail to see why only Intel could offer this technology and thus use it as "weapon" against ARM.
More companies offer wireless charging ( already 20 years ago my tootbrush used wireless charging). Besides that ARM processor are much more energy efficient than Intel's.
On the other hand, I don't mind connecting my laptop to charge. Where is the big user benefit? Also the wireless charger requires you position the appliance at a precise location.
