'Wireless charging' in Galaxy S4 will betray Samsung's best pal
Samsung will embrace Qi wireless charging for its highly anticipated Galaxy S4 flagship smartphone, due to emerge on Thursday, we're told. By plumping for Qi, Sammy will betray Qualcomm: both companies are founding members of the Alliance for Wireless Power, which touts an over-the-air charging system called A4WP. This rivals …

Since the charger needs a wire
Is it as wireless as a so called cordless kettle?
If you don't like a USB plug, a round jack or a dock, then I suppose you need it. But any range more than a few cm or so will cause issues. Inductive charging is just about ok, RF charging a stupidity.
You are STILL going to trip over the cord of the charging mat and forget where you put it or its wired "wall wart".
Extra expense for little value, a marketing gimmick?
Re: Since the charger needs a wire
It stops being a gimmick once it becomes ubiquitous. When you can stick your phone on your desk at work, your coffee table in your house, your bedside table, on the table in the pub or on the dashboard of your car and have it charge without you needing to plug it in it becomes useful.
If the only way of using it is as currently, via a special charger, then it's no better than the desktop charger on the MicroTAC http://en.wikipedia.org/wiki/Motorola_MicroTAC
Re: Since the charger needs a wire
Smewhat more than a gimmick - the idea of standardising it is that you can place anything on one of the pads and the pads will be fairly ubiquitous.
In my case I'll be happy. I'm rough on phones and the charging socket is usually the first thing to break after the numbers rub off the keys.
Frying of testicles
Does it come with aluminium gooly protection?
Re: Frying of testicles
I can see why owners of aluminium goolies might be concerned, but unless I've missed a big advance in prosthetics technology the risk would seem to be manageable?
@ aluminium goolies
The real issue is naked trampolining. It sounds like a set of clackers as you jump up and down.
Induction...
Might there be a danger with implants such as pace makers? I'd read that the verdict is kinda out on induction burners.. Well they certainly were not confident enough to say there wasn't *any* danger of direct or prolonged exposure.
Re: Induction...
Do not put hands with rings on fingers directly over induction hob....
Apart from that I've never noticed any issues.
Note 2 - smoe have hacked it
From reading the Note 2 forums on XDA there have been a variety of hacks to make the wireless charging work - just a real shame Samsung is so totally crap with it's own accessories...
"Apple will also start using wireless charging this year"
Welcome to the party, where have you been since the only flagship product released last decade?
"Apple will also start using wireless charging this year"
"Apple will also invent wireless charging this year"
There, fixed that for you.
A4WP was late
A4WP was late. Qi has already been adopted.
The very idea of distance charging would scare people off anyway, and no-car maker would ever built it into the seats because if it ever turned out it could be harmful they would be liable for unlimited damages for fitting a £5 phone charger.
I have a Qi charger here on my desk. It works fine except I have to take the phone out of the rubber case. I suspect if I hadn't bought a cheap one I wouldn't need to take the cover off. The tech works, Samsung would have been stupid to adopt the untested A4WP standard.
Re: A4WP was late
It doesn't sound much more dangerous than heated seats, to be honest.
Samsung not supporting own standard
If you can't beat them, join them right!!!
Apple just invented a new wireless charging system too wow, pity they could not get it into the utterly boring iphone5...
QI....I like mine
Charges my Nexus rather quickly. Plus on the day I got it everyone in the office asked to try it out with their Jesus phones and being the evil bastard I am I let them all try it. Shame the Nexus tablet I have doesn't support it - maybe nexus time.
A couple of questions
What is the operating frequency of the charger? What about the harmonics?
Will it upset the wireless operation of my other gizmos?
Will it interfere with my short wave and VHF (long distance, weak signal) radio listening?
Thanks.
A4WP is over.
QI is the only established standard.
and as for Apple, well Apple is being Apple and doing their own thing. Expect the £150 iAirCharger that does the same thing as as a £30 QI charger, but has premium Nano wire coatings on their coils that enable better electron flow (or some other bullshit to fool the gulible iTards).
Arg
So instead of all phones (except Apple) using the same thin mini-USB cable for charging, there will instead have to be several charging slabs stacked on a counter somewhere for all of the competing units? Plus when traveling I'll have to take one or more of these slabs with me? Great.
Re: Arg
My Touchstone dock has a micro USB socket so the lead can connect direct to a phone. But I much prefer the reversible magnetic plug on my PlayBook. For no apparent reason, the new BlackBerries can't use it. Marketing departments, walls, bullets.
Car Chair?
Is it called a car chair in the UK? Huh. In the States we only call a thing a chair if it can be moved to a different location.
What do you call the thing a baby human sits in at a the table?
Re: Car Chair?
"High chair."
I'm in the UK and I would use "car seat" not "car chair" for similar reasons
Apple will also start using wireless charging this year ...
APPLE is not know for using KISS design principals so you can envisage them using yet another non-standard device. It could have a unique modulation schema, with reception only possible on genuine iCrap, coupled with serial number verification, etc.
The EU should mandate inter-operability for these things.
Still, living in the copyright free area of the world, where fully compliant Apple umbilical cords, complete with switching chip, cost USD$5, I am sure our Chinese friends across the border will circumvent any pseudo-security proffered by Apple and at a fraction of the price.
There are several third-party solutions, the most common one being used with a Touchstone charger. A search on eBay will bring results, although if you fit the wireless charging back it blocks the signal from the NFC reader.
