Standard Cellphone Chargers For Europeans
k33l0r writes "The European Commission is confident that all major cellphone companies have reached an agreement on a standard cellphone charger for consumers within the EU. 'People will not have to throw away their charger whenever they buy a new phone,' said EU Industry Commissioner Guenter Verheugen.
Nokia, Sony Ericsson, Motorola, Apple, LG, NEC, Qualcomm, Research in Motion, Samsung and Texas Instruments have all signed the agreement."
The story is incorrectly tagged miniusb. It's actually micro USB (which is an inferior connector, in my opinion) which is slightly smaller and lacks the "ears" of mini USB, which is what the Blackberry uses.

The Commission said the agreement would involve the creation of an EU norm, and that the new generation of mobile phones would use a standard micro-USB socket to ensure compatibility.
4th paragraph
I do not support "The Man". I also do not support your irrational stupidity
My girlfriend and me have both a Sony-Ericson phone, bought 3 years apart. Guess what ? Both chargers and connectors are proprietary, fragile, weird and different! Of course if you lose it you'll have to spend an arm to get a replacement.
However this will only work if vendors give the option NOT to get a new charger with a new phone. Otherwise, this will not be really useful.
I take it that Apple isn't part of this little bandwagon.
L2RTFA. They agreed to it.
I do not support "The Man". I also do not support your irrational stupidity
press release and a memo.
Most interesting parts:
Incompatibility of chargers for mobile phones is a major inconvenience for users and also leads to unnecessary waste. Therefore, the Commission has requested industry to come forward with a voluntary commitment to solve this problem so as to avoid legislation.
and
Industry commits to provide chargers compatibility on the basis of the Micro-USB connector. Once the commitment becomes effective, it will be possible to charge data-enabled mobile phones from any charger compatible with the common specifications.
NB: The message above might reflect my opinion right now, but not necessarily tomorrow or next year.
You mean the manufacturers will be able to make the charger an accessory.
Well, isn't that a good thing? What would be the logic of this agreement if the companies just continued supplying chargers with each phone?
That's because Verizon locks their phones down big time. Since the phone detected a USB data connection, it refuses to charge.
RTFA
It will be Mini-USB. However there are 2 issues still to clarify.
1. Will the phone be required to charge at the standard voltages delivered by a PC USB port? I would hate to see that BS achieved by Motorola, where you can only charge on a PC if the Motorola Charger is installed. I would prefer if everyone else has to change to match Blackberry. If my Blackberry runs low in the data center I can just plug into any exposed USB port on a powered up server. . A Dell waiting at the BIOS screen or a SUN in full production.
2. Will this be coordinated with the Chinese standard? If both the EU and China agree on a standard, India and Japan can be convinced to adopt it. Leaving America to figure out which direction it wants to go.
--= Isn't it surprising how badly I spell ?
The dock connector already accepts USB charging.. they just need to produce an adapter cable - which knowing apple will be an optional accessory costing arm+leg.
Believe me. The EU would sue them to hell for this. They will pull a Microsoft punishment on them.
Any sufficiently advanced intelligence is indistinguishable from stupidity.
MiniUSB is rated for 1000 connect/disconnect cycles
MicroUSB is rated for 10,000 connect/disconnect cycles, and is also thinner by about 1.5mm (critical on modern thin devices).
Given the power consumption on some smartphones, having the more durable connector is IMO, essential.

This is part of the USB spec. Originally USB hosts were only required to provide a certain amount of current to devices. Later they decided to increase this, but to provide backwards compatibility the device has to ask if the host is capable of sourcing that much current before it starts drawing it.
America will use the same charger standard when the chips for power and charging based on that standard become super cheap. Which will be the case a year or so after the standard is adopted.
There is a lot more to it than just having a micro-USB connector (people say mini-USB, but they clearly did not RTFA). A lot of us in consumer electronics, especially mobile devices tend to do crazy things with charging. Like run the USB ports at 6V+ when charging. Or have special resistors shorted over the data lines to detect a "carkit" versus a PC. When you charge on a PC you have to negotiate with the PC on being able to draw more than a 100 mA before negoiation (which you have a short period to indicate the amount of load you actually wish to draw before being shut off by some hosts). The maximum of 500mA is not really enough for good fast charging of beefier mobile devices (like some GPS units and book readers), so the chargers that come with it almost always provide a lot more power.

Lithium ion cells are standardized. Rebuilding the batteries by opening the casing and replacing the cells is often possible. But lithium-polymer cells are a different story; in order to use every bit of space inside the battery or device, the cells are shaped to fit it. So it really IS difficult to implement.

Well, I haven't done the direct research myself, I just know what I've read.

Do not meddle in the affairs of sysadmins, for they are subtle, and quick to anger.
... You observe that phones have non-standard connectors and therefore require special cables to be connected to computers. A standardised charger requires a standard plug. I expect that this standard plug would not just be used for charging, but also for connecting to computers. The issue will therefore be addressed in parallel. ...
So it seems they are aware of the issue and 'addressing' it. I'm interpreting 'expect' in the sense of 'England expects every man to do his duty' rather than 'I expect it'll be alright'.
Add to that, when their usb implementation is properly following spec, the maximum draw is 100 mA when connected, and then must do a software handshake to get the full 500 mA. That can only be done by either installing the drivers (Nokia Suite is a large wad of rubbish), or having the drivers come with the OS (bloat bloat bloat). So unless you always charge at your own PC (which, on trips, is not something you do a lot, unless you happen to carry your laptop everywhere), you get a sucky 100 mA from the wall, or they are ignoring the spec (which means, stick another phone on it using another variation of the spec, things can go poof by overcharging).
Since the USB spec doesn't allow a whole lot of power, you'd need more charging time. My E71 can draw 800 mA at 5 Volts, so my 1.5 Ah 3.7 volt battery is full in ~1.4 hours, while at 500 mA around 2.2 hours, or at 100 mA around 11.1 hours. Not something you're willing to do every night in some hotel, especially with power-sucking smartphones that die within a couple of hours/days.
Sure, everybody charging their phones on the same connector is fun and all, but my Nokia charger is around 4 cc, and you get one with a new phone any ways. My dad and mom both have Nokia phones (My mom has an older model with the larger socket, but a simple €5 adapter works great), and many people do, so it's never a problem to charge your phone when you don't have your own charger around.
I'll have my standard nokia charger please, and add to that, I'm not that fond of the micro-usb connector. It feels a bit flimsy.
Not enough detail in the article, but most likely by following the USB Battery Charging Specification. (Which was, unfortunately, released long after numerous "de facto" standards for signaling dumb chargers became prolific, most of which involve tying mini-USB pin 4 to ground with varying amounts of resistance. This can't be done in micro-USB, as micro-USB has specified meaning for pin 4.)
Does your Pre draw 1000 mA from a computer, or from a "dumb charger" that signals itself as such?

Not really Motorola's fault.
Drawing more than 100 mA without negotiating a host connection is verboten by USB
Drawing more than 500 mA from a USB host is verboten
So "dumb chargers" that supply 100 mA to a device need some method of signaling this. Unfortunately, the USB Battery Charging Specification was released way too late in the game, after a number of "de facto" standards (most based on using pin 4 of the mini-USB connector) cropped up, with the typical difference being resistor values.
Motorola/BlackBerry: 220k or 440k to ground depending on charger current rating
HTC: Dead short to ground
Garmin: 17k to ground for 1A, dead short for 500 mA
