Micro-USB Cellphone Charger Becomes EU Standard 302

An anonymous reader writes "The European Commission has put into effect a June 2009 agreement stating that major cellphone manufacturers should standardize their charging/data connection ports to the popular Micro-USB format. CEN-CENELEC and ETSI provided the standards by which these 14 companies will abide to make cell phone recharging and data transfer easy." Apple may even bring the next-gen iPad along for the ride.

      I would guess that most companies are going to bring it over to the US by default. If they have to design the EU versions with micro usb then hopefully they wont reinvent the wheel to redesign it for a US release.
      • They won't redesign anything important, but I'd bet a few will still throw on their proprietary connector, which coincidentally has four meaningful pins and a size that fits a particular hole in the case.

            That is what Nokia already does: my new E72 charges with micro USB but still has the traditional thin version of ther Nokia charger which charges much faster. Since I had some of these chargers already I'm using that now, the only times I charge via USB is when I need a data connection anyway. Biggest advantage is that tethering via USB won't drain the phone battery now that it charges via USB (my laptop battery is another matter of course).

          Worse, they might corrupt the whole idea by supporting USB, but requiring the charger to authenticate itself, and either refusing to charge or deliberately drawing less power when you detect the wrong charger.

                1.8A would be great really, but maybe not practical (considering size of charger).

            • The USB standard covers how much power a device is capable of drawing. Even the $2 chinese USB wallplugs, or USB cigaretlighter plugs can power even the toughest load a USB certified device is capable of drawing. Do anything else and you run the real risk of damaging computer's motherboards. The parent's concerns are quite valid.

            and either refusing to charge or deliberately drawing less power when you detect the wrong charger.

            One could argue based on the power management portions of the USB specification that drawing less power meets the spec, but refusing to charge does not. A device MUST NOT* draw more than one unit of current (100 mA in USB 2.0) until it successfully associates to the host controller. After a device is configured, it MAY request up to five units (500 mA) but MUST NOT draw more than the host says is available. The recent Battery Charging v1.2 spec [usb.org] specifies a protocol on the data lines that devices can use to detect dumb chargers and chargers that can provide more power, so that devices know when they MAY deliberately draw more power. You SHOULD support manufacturers of phones and other devices that support USB Battery Charging.

      • I don't think they will bring it over to the US by default. Or at least not voluntarily. The main reason why cellphone manufacturers switch to connectors that are 0.05mm smaller than the previous version, is to sell more spare adapters. This practice makes them a lot of money.

        I think that they will only switch to one common standard if (a) having two production lines for european and other phones gets more expensive than having one (b) the government forces cellphone manufacturers to do so.

          Who does this? I've only owned phones from Siemens, Sony Ericsson and Nokia, but they've all been compatible with chargers from the previous generation. The only exception is Nokia, but they included an adaptor with each phone that let you use it with the older charger for several years after moving to the newer form factor.

      • Bear in mind that a lot of phones get their own specialised outer casing compared to the standard version, so I doubt it would be much work to just make a small modification such as the socket.

        Take for example the HTC Hero: Standard Version [letsgodigital.org] and the American Version [zdnet.com].

    The claim that iPad 2 will have Micro-USB port in TFA hinges on this:

    The most recent rumor, courtesy of the Mobile Review blog editor-in-chief Eldar Murtazin, says the iPad 2 will include a USB port. ...
    AppleInsider reports that Murtazin is a trusted insider with good sources

    That's as incorrect as it goes. He's an "editor-in-chief" of an organization that consists of precisely one person, namely him; and he is well known in Russian Internet community specifically for making wild and unsubstantiated predictions, often also claiming "insider info". The majority don't come true. So if that's the only source of that information, I would be wary about its correctness.

    That said, if EU mandates micro-USB, it would seem that Apple won't get much choice there for iPhone, and then it would make sense for them to align the rest of the line-up with it, even if the law doesn't apply there. So it doesn't take an insider to make an educated guess here.

    In fact, I'd not seen a device which had one before a few months ago when a couple of phones started to use it. Mini-USB has been the standard for years and is only fractionally larger whilst being much stronger.

    I would suggest that that has been the primary reason for this choice - to continue the decades old tradition of delicate connectors to facilitate the upgrade path.

      Mini-USB does look stronger, although according to Wikipedia, Micro should tolerate more connect-disconnect cycles.

      • The micro-USB connector itsself is more durable, but from what I've read above, there does seem to be an issue with the way it's mounted. The contact area of pads to circuit board is small, so unless the connector is properly attached with thru-pins it can snap right off the board very easily - and in tight-margin products, it's tempting for manufacturers to save a cent per device by skipping the thru-pins and just relying on the solder pads alone.
