Google announces Wireless Charging Orb for the Nexus 4

0. phoneArena 29 Oct 2012, 12:23 posted on

We knew that the LG Nexus 4 would have wireless charging available, and now we're seeing how Google plans to make that happen. Along with the Nexus 4 announcement, Google has shown off the Wireless Charging Orb for the device...

Could these companies call wireless charging in its current phase as induction charging and not wireless charging since its not exactly wireless?

I suppose it would be better described as "contact charging" because, yes, the phone must be in contact with the charger. But it is literally wireless...lacking a wire.

Actually there can be few millimeters distance between the dock and device but it may even more affect charging speed.

I do agree with you but you don't have to connect any wire to your phone so it is indeed wireless.

Since there is no connecting wires between the dock and device it is "Wireless Charging" but yes in science it is known as "Induction".

Also I don't feel need to use wireless charger at all! I even don't see how it could be more user-friendly, It is almost the same way as you charge using charging dock, wireless charging is much slower than usual charging. While using wireless charging you can't normally use your phone while keeping it in your hand. Also wireless charging is not good for your health!

But at least WiFi is useful.

I haven't encountered any reliable proves for it's unhealthy influence yet. If any of you could share some interesting links about it, I'd be grateful.

I'm guessing "wireless charging" is a marketing thing, more people can relate to that rather than seeing induction charging and being confused by what method of charging it is. To techies, the name induction charging makes sense, but out of that scope, to the average smartphone user, it might not make sense.

will it take the same time to fully charge the phone as the wired chargers?

It's slower.

that looks very very nice. but still wondering where's the charging port at?

its wireless induction. It charges while it sits there.

They need to have that be able to work in the car. It would make a swank little dash mount for GPS/ hands free. Might need to make the magnets stronger to hold during road bumps though.

Charging from a 12V outlet is slow enough, so if induction is even slower, what would be the point? Just get a charging car dock.

That sound like a good idea? But if the car charger is faster why bother. I mean is cool an everything but like roldefol says what would be the point

There is no need since you can use dock-holder in your car and charge it in usual way wich is faster than wireless charging.

I do not really understand why Qi is being introduced instead of WiTricity.
As far as I understood:
1. The range differences:
* Qi transfers energy over a maximum distance of 1.6 inches;
* WiTri's relatively efficient range is about 7 feet
3. The efficiency differences:
* Qi has maximum 60% efficiency over the said 1.6 inches (yes, you loose 40% energy - wait longer for battery, spend more on bills);
* WiTri has 90% efficiency over the distance of 3 feet.

In both solutions the amount of power you can receive dicreases with the distance from your charger to your phone. None of them has negative effects on health or environment. Why they pick the weaker one?
I'm not lobbying about WiTri, nor even favoring it. I'm just curious what I missed about those techs. Maybe some article, piece of news, any constructive answer? Anyone?

My bibliography about WiTricity:

Loads of ads and reviews around the youtube, tech-fansites. You can even test it yourself.

"None of them has negative effects on health or environment."

Wrong.

As I said, it is not an opinion of mine, but just an effect of reasearch I've done. I'd be happy to read about tests proving such effects, even some loose articles, hypotetics. If you know some reliable sources I'll read them all, from cover to cover. Just drop a link, thumbs up in return.

Where's the orb's wire? It has to be plugged in, right?
