iPhone 5 launch
I fully understand why they prefer to use a dock connector, USB is not really suitable for connecting accessories on a phone. USB works well on a PC, the device identifies itself and the OS goes off to get and install drivers. This doesn't work as well for embedded devices, this is why there are loads of iPhone docks and car connections / controls - but few for other platforms. The 30pin connector allowed direct access to these functions without the abstraction that USB would introduce.
From a technical point of view, they should use their own connector. From a user point of view, it's annoying that everyone used to use different chargers!

liked them all (except the windows phone and their stupid ways of connecting to exchange server requiring you to create download and install a certificate :nutter
You only need to do that if you're using a self signed certificate. But I agree it's a tad over the top :bang:.
exactly, Whereas Android and IOS doesnt require this. IIRC you just confirm the self signed cert. I also remember 7.0 (i think it was 7.0) just didnt work with exchange 2007/10 and remember reading for hours how to fix this even coming across a certified exchange 2007 master who spent 10 hours attempting it but giving up.
It would only be microsoft who could make their own products incompatible.. atleast its all fixed now in 7.5..

I find it immensely amusing also. I find the best implementation of Exchange Activesync to be Android, followed by iPhone and THEN their own devices .
Oh well joys of working in the industry.

I am obv not that clued up on how the wireless charging works, I was just stating that it would be a completely useless gimmick to most people. NFC standard.... it doesnt come with NFC technology in it so that might be difficult.
Yeah I would prefer to carry a lead that connects power sockets rather than a lead and a pad, and I would assume that power lead charging will charge my phone quicker than the electromagnetic field technology?
If it was spitting out Alpha Particles then it wouldn't really damage most humans unless they ingest it, they get stopped by skin normally or a piece of paper.....
Nope, not without the transformer built into the plug connector
the EM technology can actually charge faster than a standard socket. This is because the larger coils and magnets (or a transfromer...) actually match more perfectly to the batteries preferred current and voltage, to what a socket can do
No need for that, I am obv uneducated on how it all works, most wireless technology is based on radiation so I made an incorrect assumption on how the power was transferred. Instead of laughing you could educate me......
Is it more efficient than wired charging and will it be quicker? I would think it would be a major hassle to most people to keep their phone in the same place to charge it for hours, even if I am sitting at my desk or at home unless I am asleep, I am always moving paper and other bits around my desk if knocked it off the charger then I would probably not notice.
So the charging Pad will kick out the 50Hz 240v but in electro static field mode, or does it also require a transformer?
They will technically have to do a micro USB to thunderbolt one now as well! Even more money!
Apologies. and i did in the post that i put below that. I didnt mean to cause offense was laughing at the radiation, not you
A transformer works by passing a current through a coil wrapped around a ferrous metal (like iron) to create a magnet. another coil around the same metal structure next to it picks up this magnetic field and creates a current.
To create different currents and voltages you adjust the amount of coils in the structure or use a bigger piece of metal.
If you want to go from Low Current high Voltage to High Current Low Voltage you use a large coil for the input and small for the output.. and viceversa

Yeah I know how a transformer steps up and down and why they used to be huge! but is one required to take the normal house voltage to one that would be used in the wireless charging pad?Apologies. and i did in the post that i put below that.

yeah. thats all its doing. but instead of using the magnetic flux withing the core its using the mangetic field. the reasons these ones are huge is that there going from 1,000,000v in the Pylons to 240v for household usage.
going from 240v to 12v for a battery is nothing. A battery doesnt need high voltage but high amps.

This might help. not wanting to make anyone sound stupid
Inductive Coupling
Inductive coupling uses magnetic fields that are a natural part of current's movement through* wire. Any time electrical current moves through a wire, it creates a circular magnetic field around the wire. Bending the wire into a coil amplifies the magnetic field. The more loops the coil makes, the bigger the field will be.
If you place a second coil of wire in the magnetic field you've created, the field can induce a current in the wire. This is essentially how a transformer works, and it's how an electric toothbrush recharges. It takes three basic steps:
Current from the wall outlet flows through a coil inside the charger, creating a magnetic field. In a transformer, this coil is called the primary winding.
When you place your toothbrush in the charger, the magnetic field induces a current in another coil, or secondary winding, which connects to the battery.
This current recharges the battery.

My point was that Apple don't like to use standards, unless they're ploughing on and making their own new ones. The iPhone lacks wireless charging, but it also lacks NFC - NFC would be a good to initiate the charging.
Wireless charging clearly isn't suitable for all, and it shouldn't be the sole way to charge the device. I actually agree that until it's standardised properly that it IS gimmicky. NFC on the otherhand, has been around a while - hell I have it in my 2 year old phone!
I'm aware that Alpha particles are stopped by skin / paper etc - it's why I cited that as example, rather than going really daft with something gamma rays!
lol
calm down,its not £15
Its £25!

That's not the one we're talking about. That's the old style dock to the new mini dock. Not the mini dock to micro USB.

FFS!!!!! You can still charge with a cable! Why does everyone assume that because you can charge wirelessly that you can't charge with a cable
