i think wireless charging is cool.. neat..
but how good is it?

with the world going green and being more efficient with power and it's consumption... reduced pollution.

how efficient is it moving the energy from pad to phone?
wouldn't there be a lot of wasted energy moving the power? and how much do you think is lost?

i am sure it is very convenient to have this feature.. and also not breaking your usb port with over usage or stress on it.

but if you are low battery, but still want to use the phone (calls or surfing), only a charging cable can let you do this.
 
I use wireless charging on my phone and love it. Any loss of efficiency can't be significant can it? I can't say that I've seen any impact on my electric bills, but that's just one person's experience.
 
Yeah I haven't seen what the efficiency of it is. But it sure is more efficient of my time :)
 
The only issue with Wireless charging is a lot of devices still aren't compatible, yes you can mod your device but it is risky.

I like the idea of it, just because when my phone is sitting next to me when i am on the computer it could just be charging on a pad :)
 
Just watch out for the power transmission beams because they will erase your data and fry your brain cells. Wireless power is the devil's doing and I'll have no part of it.

And I hear you need a permit from the ATF to use it because components of the system can be weaponized.

When Canada invades, the first thing the Canadian armed forces will do is look up those with wireless power capabilities and come after you.

I use wireless charging on my phone and love it. Any loss of efficiency can't be significant can it? I can't say that I've seen any impact on my electric bills, but that's just one person's experience.

Not sure the power loss is easily measurable by the typical consumer. Not sure it is not easily measurable by the typical consumer, either. I am sure it can be measured because such things can always be measured.

Buy a Tektronics Model 4-11B Power Measuring Flux Capacitor Triad Matrix Monitor with the Type Three Flux Measuring Capacitor rather than the Type 4, which is not as easy to read unless you have a good slide rule.

And remember, if it is costing you .0012 cents per month more, those costs will add up and it twenty years, you will discover that using your wireless chargers actually cost you 13.6 cents more.

That is a few cents more than a package of those Raman Noodles, for
God's sake!

If Big Power gets behind it, just assume it is to better their bottom line and just assume it costs a wee bit more. They are counting on the billions and hundreds and many users to switch over because they are greedy.

But in a decade, we will elect a King who will mandate we all use WP.
 
the pad has to be plugged in at all times.. so the pad is consuming power when just waiting to be used (even when not putting out waves). i have heard that plugged in items is one of the main lost of energy. think about all the things in your house that are just plugged in doing nothing, consuming a little itsy bit of power... all those hrs in a year.

then there has to be some loss through pushing out power via wireless. cant be 100% efficient... i would guess at least 5% loss.
then you have the waves that the device is not capturing.. just lost.

i agree the tech is useful and very easy...

but you take the small loss ..
multiply that by the hrs per day .. per year...
multiply that by the number of potential users for the near future...
world wide...
that has to equal a very significant amount.

i dont know.. just thinking out loud..
i might even be one using this tech soon too...
cant fight against advancement of tech...
makes our lives a little bit easier...
 
If you need to place your device on a special pad to use wireless charging, I say you should just stick with the old system. I mean, how hard is it to stick the little pluggy thingy in the little pluggy thingy socket thingy? What are we, too lazy these days to plug our phones into little pluggy thingy sockets?

Give me a break. Stossel will probably do a story on it.

Until Rush says it is OK, I will stick with my little pluggy thingy, thank you very much.

I do not want my unborn children exposed to such things. Why do you think I switched to boxers and now use my old briefs for cleaning spark plugs and piston ring grooves? Too many years watching my rad emitting TV and the constant exposure to my full gallon linear amps means I'll likely have two headed kids with fins or perhaps flippers.

Remember, two heads means you must buy two cells per child.

Wireless charging is useful (for me) if you (I) can simply begin the charge process when you (I) enter the room. Then you will see lots of news stories about how wireless charging causes cancer in lab rats and there will be law suits a plenty.

Besides, until it is free, you must factor in the cost of the equipment to determine if you saved money. Compare the cost in amp hours times calories expended when you search for the proper pluggy thingy divided by Kilowatt hour of power times the life of the devices you use to charge your devices as well as the device you are charging plus the cost of a new cord when Android changes to the Lightening type 12 plug.

Add the cost of adapters and you will discover it costs 14.00 more per month to use wireless compared to wired charging.
 
Well, for me, I don't have a good place to set my cable. If I leave it far enough out on my nightstand, where it overhangs the entire stand, it gets caught in the drawers. Or even better, when I open the drawer it yanks my phone off the nightstand onto the floor in a trebuchet sort of action. If I don't hang it far enough out it slides down, I have to go digging behind the nightstand for it. I know, first world problems, but I enjoy using the creature comforts that technology has given us...

P.S. and who knows, maybe the extra electrical field will stimulate my brain at night, and I will become a super genius or something! ;)

Interesting that you "have heard . . ." You do not know, do you? NO OFFENSE MEANT! Lots of people do not know the numbers. I do not know the numbers, either. Seems my cell might add a buck to the bill at the end of the year, I just do not know.

I do know it cost more power to run my old phones and devices like the fax than my little cell costs me to operate today. OK, I am guessing but it seems logical to me.

It is my power to waste, is it not? Not sure who is hurt if I use the power I pay for, the way I want to use it. Is it the effect of the millions of users using tiny bits of power added up is killing Mother Earth? Is it because we must be green or fry in hell? Is it perhaps because you Androd Fanboys will opt for any old cool sounding thing? :D

Perhaps it is the desire to sell us something new and Buck Rodgers-ish because marketing people are running out of things to sell us cell users. Yup, that's it.

Or is it we have plenty of power and we are too dumb to know this and a few tens of millions of cells really do not hurt? Help old fart Bob out and 'splain it to me.

How about a world without cells. Which cost us more power, those millions of touch-tone and rotary phones, the extra money to deliver and process the mail, the cost of all of that Jet-A, the millions of fax machines and ink and paper or the millions of cells this do it all with a simple battery and charger per device?

What about it . . . how do "they" determine the damage our reckless use of power causes or will cause us down the road? Never been able to figure it out.

Wireless charging is a myth. If you need a device like a pad, it is not truly wireless. But for me, I define wireless charging as something that happens when you enter a room with your cell and it begins to charge.

Just think of it. Wireless charging in the bathroom. Charging in the car and on the boat and train. As I walk down the street. In the office. Never worrying about a full charge again.

It will be glorious, I tell you what.

Until it becomes Laetrile, 2015.

Think about the costs of going old school vs. using a cell. I'll include tablets in this as well.

There was a time when we used tons of fax machines. My cell costs money to operate, but I use it for email and SMS. Far less faxing these days a going on at Cassa Del Bob's Office.

I think our devices save money and power because in the good old days, the devices or cells replace cost more to operate. No more faxes (well, a few I suppose) or paper or ink or gas to get replacements. It seems to me, my cell adds to the power bill, but the added cost is offset by the cost of other things so the savings is there.

I think wireless charging is marketed as more of a convenience item than a way to save power, however.

i think wireless charging is cool.. neat..
but how good is it?

with the world going green and being more efficient with power and it's consumption... reduced pollution.

But if it is a green thing, is it really green? Not sure there is really a savings in power, is there?

Consider the fax or the letters we once created in the good old days. My question is which costs us more power: sending a reply by email with an attachment, or all of the costs associated with writing a letter and mailing or faxing it?

You have the costs of power to make more paper. The adhesives on the envelopes and the stamps. The manufacturing costs include raw materials delivery to the factory; the costs associated with delivering the materials to the store and the delivery costs to your office or home must be added, I should think.

And the gas you use to visit the Post Office.

Perhaps I am over analizingm, but it seems gong green should mean that we should use more tablets and laptops and cells rather than reverting to the old ways.

Anyone care to point out my faulty reasoning? I'll listen.

Seems we use more raw materials these days than we were told we will use by going paperless. I have 5 printers these days and i still attend meetings which cost me.
 
bob, you have a very good point..
today compared to yester-year.. yes.. it has been a huge improvement.
less over all consumption of raw material using today's mobile devices.
a lot less.!!!!

and it is everyone's individual right to use and pay for what they want...

but this was more of a discussion about today and moving forward...
the wireless method does use more to do the same thing as .. usb wired charger.
and it does cause waste of resources... that the future can use.

and as individuals we can do as we wish.. but we are now a global community.
and USA.. is a country that is a huge raw resource hog... just sayin...

**** note ***
i aint preachin... this is just a discussion.. dont get me wrong.
because i am part of the problem.. and not as green as i should be.
love my lux stuff and creature comforts and toys.. etc.. too

Preach away.

Until laws are passed that alter our lives, we will "waste" away. And when laws are passed, people that love being green will quickly change their minds.

To return to the OPs query about wireless charging, I am all for it. I changed my mind. Cool tech if it works. It wont save any energy, but as I said earlier, that is likely not the point of these devices. Convienence is I should think.

but you take the small loss ..
multiply that by the hrs per day .. per year...
multiply that by the number of potential users for the near future...

Let's assume it is a significant loss. My question would be is that "significant" loss greater or less than the old way? One really needs numbers before any significant loss can really be called significant.
 
Interesting topic guys, so let's take this over to our Android Lounge area. :)

Again I do agree it is better than before.. But don't forget to note the added loss from disposable mobile device in landfills

Just because you find a way to save something.. It doesn't mean you SHOULD waste in others..
Example : if we find a way to save 1000 kids from dieing from hunger in India.. We can let an extra 800 kids die in Cambodia.. Still up 200!
 
I use wireless charging on my phone and love it. Any loss of efficiency can't be significant can it?
It sure can!

Practically everything that plugs into an AC outlet uses a transformer to raise or lower the AC line voltage (and to isolate the live wires from the device's chassis). All wireless chargers take advantage of this by making the transformer into two parts: one in the charging surface and the other in the device to be charged. It sounds neat in theory, but efficiency can't match that of a traditional transformer because (this is the simple version) efficiency decreases by the square of the distance. So going from wires wrapped close together to coils that can be several millimeters apart is a lot less efficient.

More convenient, yes. But at a price. I doubt any of these wireless chargers would get Energy Star certified.
 
Here's another angle on it ...

I have a Sony Xperia GO, it's waterproof (I've tried it in a bucket of water), I bought it because I'm a pretty "outdoorsie" type and I use the GPS with an OS maps app to navigate. It's good to have the confidence to take the phone out in thick mist and horizontal rain to consult the maps. You wouldn't do that with an iPhone!

But, it's only waterproof with the little plug for the charging socket in place. While it's charging, the plug hangs on a dodgy little bit of plastic and I have worries about how long it'll be before it snaps off and gets lost.

This phone is crying out for a wireless charging option.

OK.. That makes sense.. Waterproof devices.. No open plugs.

Till they design a better plug
 
But here's another angle to look at this. This just happened to me.

Charging port went bad. My phone was rooted. couldnt connect or recharge. If it weren't for the "universal unroot" app, I would have been SOL and warranty would have been voided.

That port has gone bad many times on different devices for me. WC is great.
