Wireless Charging On the Droid Bionic?
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)?"
Sarcasm? Palm\HP's have had inductive charging just like this since the Pre surfaced two years ago, powermats have been out for almost as long.
As I gaze over to the Palm Touchstone inductive charger on my desk that has been there almost 2 years, meh is the best i can muster.
Good-bye
Want to be on top again? DONT CRIPPLE THE DAMN PHONE!
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.
Do not look at laser with remaining good eye.
Except with a worse OS...
I've just switched from a Pre to an HTC Android phone (contract upgrade), and the Pre definitely had the edge for usability.

Well patents may have been a hindrance but I think practicality was more an issue. I have one of those toothbrushes and it takes like 8 hours to charge. Since I only use it twice a day for 4 minutes total a day, a charge lasts weeks. For a phone that requires a faster charge time and requires more frequent charging, this technology while possible may not have been practical until battery or technology changes.
Well, there's spam egg sausage and spam, that's not got much spam in it.

sounds cool but i have like 10 free outlets at work for my phones, ipad and whatever i carry these days to charge. and you can use USB ports on any server in the data center if you're working away from the office.
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
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.

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.
Inductive charging will be a valuable asset when a room, a house, or even a city can be blanketed with the required EM field, so that my phone keeps charging all the time, and we can do away with batteries altogether or keep only a small reserve battery for 'emergency' power in shielded areas (like the inside of an elevator). Either that, or they achieve such transfer rates that I can go from 5% to 100% by holding it up to the coil for five-ten seconds at most, like they do in games (which would likely incinerate the electronics with waste heat). Until then, wireless charging will be a gimmick, albeit a marginally useful one, in all devices.
Hyperbole: I use it liberally!
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.

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.
Nevermore.
This is one of the best grammar corrections ive seen in a while. Hes not whining about your/you're etc but rather correctly pointing you dont color with pink and call it green.
Good-bye
I am certain that very few people will peruse your comment.
Hell... My Braun cordless toothbrush has inductive charging, and it's probably 15 years old now.
It doesn't matter. If Apple has not gotten into wireless charging that means nobody's done it correctly. When Apple finally does it only then will it be right and proper. Your Braun charger is merely a sloppy fragmented immature product concept that never caught on like the iPhone. You should be ashamed. No go out and by an Apple product that you can finally be proud of for the first time in your life.
I think the Interplaq electric toothbrush I used back in 5th grade when I had braces (1980's here) had inductive charging. I remember always wondering how it charged, because there wasn't any exposed metal anywhere on the whole toothbrush or charger. Of course, we didn't have the internet back then, and my 5th grade teacher taught us that evolution was "something made up by people who aren't real Christians" (why yes this was in the Bible belt, why do you ask?) so she wasn't going to be any help in figuring it out ;)
"I disagree with you" does not equal "flamebait."
It's so commonly misused that I avoid it altogether; even if I use it correctly, about half my readers will misunderstand me.
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 is a good idea, but there are at least three competing standards, 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.
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
Apple has proven that it is all about the software. They are killing with shiny but unremarkable hardware. They got killed on the desktop because of software, too. Apple ][ market perception was for games and schools but not business and the race was nearly over by the time the Mac came out, which also didn't look like a serious business machine. This time around, nobody is saying they have to have a Blackberry phone/pad because that's what they use at work.
My toothbrush can do this and has been able to for quite a few years...
Umm this may not be refering to power mats but a new form of transferring energy wirelessly using magnetic fields. I saw a demonstration on TED. This form offers true wireless charging - you have several feet to work with,with the powermats the item still has to be in direct contact with the mat to charge.
I hope I can hack into my neighbor power :)
The same idiots who drool over this will be the same idiots raving about the efficiency of their Prius.
We need to find ways to conserve energy, not event new ways to introduce massive amounts of inefficiency into a system because we're too damn lazy to plug in a cord. This sort of crap is ridiculously wasteful and lest we not forget, we're ALREADY SHORT ON POWER transmission capability. We can barely get enough energy to your house to run your refrigerator, and you want to start using devices that waste more than half the power they use to save yourself less than a seconds time?

Will this finally mean a decent (really) waterproof phone? The Motorola Defy was good, but it's not really waterproof (my brothers' needed to dry after being in the washing machine). Just fix the damn SIM cards so they do not need to be placed by customers and seal the complete phone shut. Full waterproofing, end of warranty if you open it.
Well, I might have a way, but it only works on a semi spherical planet in a vacuum.
