Wireless Charging On the Droid Bionic? 81

Posted by CmdrTaco from the stop-gnawing-on-cables dept.
mahiskali writes "New documents pertaining to the ever-hyped and much-delayed Motorola Droid Bionic have surfaced on the FCC website. Perusing through the documents, I noticed a very interesting feature: an inductive charging coil (click 'Internal Photos'), built into the battery door housing. It seems Motorola may have some tricks up its sleeve yet--but will it be enough to beat out the competition (read: Samsung Galaxy S2, iPhone 5)?"

      Although I loved my Pre, the only reason I got the Touchstone was the flap that covered the power connection on the phone - I figured it would break if I was charging every day, so switched to the Touchstone instead.

    • Even if you limit the class to Verizon 4G Android phones, this isn't new or unique. Inductive charging is already available for the HTC Thunderbolt and LG Revolution.

      Yeah, i love me my touchstones. I have one at my office and one in my car. It's really hard to appreciate them until you use one. But it's pretty awesome, to sit in my car, place my phone on a little circle then have it hold there magnetically, while charging, and playing all my music wirelessly putting my gps right where I need it.. No wires! And it knows it's in my car so it opens pandora and gps automagically.

    Make it run a clean google android, make it EASY to update with no nasty tricks to keep unauthorized OS installs off it. in fact ENCOURAGE unauthorized OS install by simply stating the warranty only covers the phone when used with a stock OS install.

    In other words... stop being jerks.

      I have no complains about their hardware. Well, mostly. Their batteries need work.
      But man, their software sucks. My aging Motorola Milestone (that's the original Droid's GSM version) will out perform most of phone around now that I replaced the original OS with Cyanogenmod.

    • You may be surprised to find his out, but what you think a company should do to be successful, probably won't work. For example, you think motorola should make it easy to update with no nasty tricks to keep unauthorized OS installs off, but the majority of people don't care. For another example, you think they should stop being jerks, yet time and time again being jerks is what makes companies big and successful. The reality is that the way you think the world should be, is not how it is.

    this sounds like cool and gee whiz but not practical for a lot of people who will just say who cares and get an iphone

    • and you can use USB ports on any server in the data center if you're working away from the office

      Maybe it's just me, but I don't plug *anything* USB into a live server unless it's a part of diagnostics. Doesn't matter if it's just to charge it, I've seen devices announce themselves incorrectly and cause a kernel panic. They make car chargers and the like for that purpose.

      • Hack apart the cable/connector, and disconnect the data lines. Sometimes that stops the device charging altogether, though, since it's waiting perpetually for the host on the other end to negotiate a full load of five units, but can't, due to the data lines being cut. I solved this by taking a USB charger and cannibalizing the cable only to get the pin-five-shorted-to-ground connector.

    • Have you considered that the inductive coil won't be the only charging option? I guarantee USB charging will still work just fine.

    • I have an inductive charging toothbrush and I honestly can't wait until every single device uses this technology

      - The contacts will never wear out or corrode, since there are none
      - You don't have to futz with jamming in a tiny micro USB cable the right way
      - You can throw your phone on the charging mat in the absolute darkness
      - You can charge your and your wifes phone simultaneously with one charge pad

    • you can use USB ports on any server in the data center if you're working away from the office.

    Could some EE closer to the inductive charge community comment on:

    1) Are the chargers "smart" like if I drop my wedding ring on the charger does it heat up/melt or does the charger recognize the inductance / current draw is way outta whack and shut off? If it shuts off does an indicator of some type turn on, or does it just not charge?

    2) Frequency of operation? I would really hate to hear anything below, say, 30 KHz. Even at my age, just years ago when CRTs still roamed the earth, I found horiz sync whine to be astoundingly annoying. I would really hate to hear a 60 hz inductor, any tropical fish owner / diaphragm air pump owner knows the annoying drone of 60 hz + harmonics.

    3) Who can sell me an inductive receiver kit to power other stuff? I'm not talking about bolt and go, but ladyada / dangerousprototypes sort of places and products? Who makes this stuff, anyway? At a superficial glance the usual suspects in the analog power community don't seem to offer any specialized ICs for the task... unless the RX has no 2-way comm with the tx and literally is just any ole coil feeding a bridge rect and a switcher.

    4) I'm sadly picturing some kind of hideous DRM where the expensive charger and expensive device need to negotiate a RSA key across bluetooth to light up the charger... Please tell me it isn't so? A generation of interoperability would be awesome.

      Assuming they're using the qi charging standard, yes. There is quite a bit of handshaking required before the charger will fully energise a coil.

      Texas Instruments makes it. They also have a devkit:

        ooh cool. too bad the dev kit is $300 and the whole thing requires licenses. I suppose the license and its probably hideous fees is what prevents ladyada etc from offering a $20 kit.

  • Inductive charging suffers from efficiency problems (86% of power drawn is transmitted, as opposed to the 9x% of a DC/DC converter chip in wired chargers), but okay, it's no big deal. However, it doesn't offer practically any convenience over wired chargers: still fixed in place over the powermat, although you just have to pick it up and dash off, I'll grant them that.

      Grandiose. I'd be happy with a magic box under my work desk and bedroom dresser that turn the entire horizontal surface into a magic battery charger. Can't lose the charger if its bolted underneath my desk. Can't fumble for cables if there are no cables.

      • Okay, I was aiming a bit higher, so shoot me. :)
        The absolute minimum this starts to become useful is your vision. At the very least, I want the table surface, plus maybe ten centimeters above it to be charging. Anything like a 10 cm by 10 cm powermat, and we're back to square one with wired chargers.
        Ideal would be a citywide or even global field, that removes the need for batteries in the first place, but that would probably have all sorts of technical obstructions, like interference...

        • According to some others comments about this phone; the coil is possibly for magnetic inductance charging, not EM. What this means is, you could put a box in your bedroom and power the whole room.

  • That word does not mean what you think it means.

    The summary uses the phrase, "Perusing through the documents." First off, you don't "peruse through" a document; you simply "peruse" it. Secondly, the use of "through" implies that the author has used "peruse" as a substitute for "skim" -- because you can "skim through" documents -- and this is doubly wrong, because "peruse" has exactly the opposite meaning from "skim;" it means "to read through with thoroughness or care [reference.com]." You'd peruse a legal document. Yo

      I disagree that it is being misused, but I agree that it is useless. It has two meanings and two usages, and so it is useless except in a clear context. In the case of the summary - the use of "through" aside - it is not at all clear whether the submitter read the documents carefully or whether he skimmed them.

  • Inductive Charging has become the new standard for some time on most Verizon smart phones at the very least. It is already available for the Thunderbolt, Charge, and Droid 3 and others, so yes, I am sure it will be available for the Bionic as well.

  • Inductive charging is a good idea, but there are at least three [wirelesspo...ortium.com] competing [witricity.com] standards [hpwebos.com], which is why it isn't going anywhere. If the industry would settle on a standard and get business hotels to put a charging pad in hotel rooms, this mgiht get deployed.

This time around, nobody is saying they have to have a Blackberry phone/pad because that's what they use at work.
