The distinction is minor (4, Insightful)

You magnetically drop your device into place onto a block on a power cord. Instead of plugging the power cord into your device. The actual distinction in convenience is a half a second of fiddling per day.

It wears out your port. I wish these phones came with tethered but removable inserts for charging.
My brother for example works in a pizza restaurant... he gets flour stuck up his charger all the time and has to pick it out.

Luckily, I leave my Nexus 7 plugged in all the time. My one gripe about this device is that it's find to find the hole when plugging in the USB charger. (flour, or not). It does seem to have a propensity to wear.

In most usage scenarios, pizza restaurants excepted, I doubt "worn out charging port" is going to be the reason you ultimately stop using the phone. I don't think I've ever had a device fail due to the charging port. For most people, wireless charging is a nice luxury rather than a genuinely useful feature.

The Kindle Fire often fails for this reason:

Both my kindle fire and my mother-in-law's kindle fire failed for this reason. Also, my three year old has difficulty getting the plug in and out, and tends to yank on the cord. With a pad, he would have no problem charging the device.

I would LOVE to have wireless charging on my Garmin GPS watch. The problem is the contacts get gummed up by sweaty grit, until it won't charge, reliably or at all. It's a persistent problem for many people with this type of device [garmin.com] .

Not true; both mine and my wife's OG Droids had worn out charging ports after about 2 years of use. I had been keeping up with the latest ROMs so the performance wasn't actually the main reason for ditching them; it was the fact that there was no way to charge them.

I think that people that don't find wireless charging to be useful and convenient are people that don't use wireless chargers.

It's nice to keep a wireless charger on my desk at work, I can drop my phone on it, then grab it when I go to a meeting without fear of forgetting to unplug it and dragging the power strip it's plugged into across my desk.

Likewise, a charger on the bedroom dresser means that I can just put the phone on there when I go to bed to keep it charged - no need to fumble with cables in the dark to plug it in.

Re:The distinction is minor (1)

somarilnos (2532726) | about 8 months ago | (#45483603)

Modern day, that's true. The problem was largely resolved with the adoption of MicroUSB for most charge cables. Micro was designed to put most of the stress of plugging and unplugging the device on the cheap, easily replaceable cable, instead of the phone's internals. Makes a big difference.

Re: The distinction is minor (1)

AvitarX (172628) | about 8 months ago | (#45483615)

I've lost 3 devices to worn out charging port (or broken at least).

A T-Mobile g2, a nexus one, and a Nokia Bluetooth speaker.

At least the speaker involved a tug on the cord breaking it off the circuit board.the phones were 12 to 18 months old, so those I think were wear.

I naught 3 charging mats for my nexus 5, and it was a selling point.

My PSP's USB charging port wore out... that annoyed me greatly. Luckily it had a traditional plug-in option as well.

Re:The distinction is minor (5, Interesting)

Andy Dodd (701) | about 8 months ago | (#45483155)

The most likely part of a connector to wear out are the springs - which is why in the MicroUSB standard, the springs are in the plug (e.g. the cable) and not the socket.

Re:The distinction is minor (0, Offtopic)

Anonymous Coward | about 8 months ago | (#45484011)

I really doubt that.
In all my experience the most likely point of failure is the solder joints that hold the socket to the PCB.

There's a reason apple went with the dock connector, and then lightning. Those interfaces are tested and rated at many more insertions than any microUSB socket will ever achieve.

And no, it's not some conspiracy to get you to buy more cables. Grow up.

Ravaldy (2621787) | about 8 months ago | (#45483197)

May not look like much now but it's baby steps like this that makes these kinds of technologies eventually become much better. If they don't start somewhere there will be no R&D money to continue and improve.

The long term objective would be to enter your house and the darn thing starts charging regardless of where you are.

Re:The distinction is minor (2)

tchuladdiass (174342) | about 8 months ago | (#45483265)

For that to happen, the charging would have to be via beamed RF energy instead of magnetic induction. What I'd rather see is a return to devices that only needed charging or battery replacements once per month or so. Like the old 2-way pagers I used to carry.

Re:The distinction is minor (1)

X0563511 (793323) | about 8 months ago | (#45483431)

That's going to require either a few breakthroughs on ultra-low-current ICs, breakthroughs in energy storage (you know the batteries we already have can explode/violently-burn?) or devices with huge battery packs...

low frequency RF =~ induction (1)

raymorris (2726007) | about 8 months ago | (#45483537)

>charging would have to be via beamed RF energy instead of magnetic induction.

At low frequencies or short distances they are almost the same thing. "Near field" is within about a wavelength or two, which at 30 Mhz is about 10 meters. So there's not really a hard cut off between induction and RF, more of a large gray area where you can say "this range generally behaves more like an inductor". There's no reason an "inductive" charger can't be tuned for charging devices within six to ten feet - anywhere in the room.

Actually, it is magnetic. Google's charger has a magnet in it and a bit of steel or something in the phone so the coils line up on their own rather than having to position it yourself.

I consider that damn near waterproof.

Re:The distinction is minor (2)

Not really. Just use an appropriate membrane over the speaker/microphone. Lifeproof has been doing it for years with their cases.

Re:The distinction is minor (1)

hypergreatthing (254983) | about 8 months ago | (#45483021)

With constantly plugging a cable in and out of a device you will eventually wear it down and break it (becomes loose, etc).

You cannot wear out a wireless charger.

That is the distinction.

Re:The distinction is minor (1)

Joce640k (829181) | about 8 months ago | (#45483573)

With Micro-B USB connectors the moving parts (spring contacts) are in the cable. It's designed so the cable wears out, not the socket. Replace the cable after your 10,000 connections and you're good.for another 10,000.

https://en.wikipedia.org/wiki/USB#Durability [wikipedia.org]

If the USB connector breaks, it's because you're a ham-fisted clod, not because it's badly designed.

Re:The distinction is minor (2)

MondoGordo (2277808) | about 8 months ago | (#45483037)

assuming you only plug it in to charge once a day ...

If, like me, you use your phone throughout the day, letting it sip juice while stopped at my desk for 10 or 15 minutes several times a day, the time savings adds up; not to mention the wear and tear on the port that isn't happening and when i leave the office it's usually got a decent charge left.

In addition since going to cordless charging I've never once forgotten to unplug the cord and accidentally yanked it out of the port or the wall

Re:The distinction is minor (1)

petteyg359 (1847514) | about 8 months ago | (#45483287)

Sounds like you'd be better off if the companies would ditch the "thinner is better" idiocy and put some decently hefty batteries in the things. My LG G2x gets a week of standby time with the extended battery I bought, and I will never purchase a device without an easily replaceable battery (as in just under the back cover, so all I have to do is get a bigger battery and fatter cover). I don't give a damn about wireless charging if the charge won't last more than a day in the first place.

I have QI wireless charging on my Nexus 7 and Nexus 4.
This is incredibly convenient. Just set the device on the charger. You don't have to fiddle with the connector (there must be a rule that you will always pick up the connector in the wrong orientation). I find the fiddling with the connector is more like 15 seconds. I don't even have to think about wireless charging. Just set the device down.
Works great.

I think that people who get some kind of pleasure out of these things are creepy.

That being said, I lost my last phone because the usb port died (got worn out), so I sprung for the wireless charging gadget for my current phone (HTC 8X Windows) so my USB port on my current phone doesn't wear out, as well.

Now why a standard product announcement is on Slashdot is another question...

Re:The distinction is minor (1)

Anonymous Coward | about 8 months ago | (#45483151)

As a sibling post pointed out, it wears out the port. In fact, my parent's Playbook has a damaged USB port and now requires some finesse to get it to charge properly. My HP Touchpad, on the other hand, still has a fully working port because I have a Touchstone (the wireless charging equivalent designed only for the TP). The only time I would ever plug a USB cable into my Touchpad is if I wanted to update Android (and even still, I could probably find other ways to do this over wireless anyway).

I got my wife one of those HP Touchpads on the $99 close-out special and loaded Android on it. Fantastic device, really, too bad they sold it with WebOS (which is fine, but nobody* supports it).

But their USB charger is fundamentally junk. I looked all over boards and everybody seems to have come to this conclusion. The wireless charger is, however, well made and so I got one, just to solve the charging problem.

The interesting thing is, it's a stand, not just a charger, so now there's a 9" information display sitting up on the desk in the living room, not just a tablet laying flat and charging. By default it goes into clock mode, but I need to spend some time soon to figure out how to make that mode show me a weather widget as well, maybe a headline or bitcoin price ticker too.

So, if done right, wireless charging can be more useful than simply saving a few seconds. My phone, on the other hand, is a regular MicroUSB, and the cable is always in the way or falling down off the desk, or whatever. I could rig up a cable management solution, but if I'm going to spend that time/effort/money, I might as well just get a wireless charging mat.

Really, it's the sort of thing that you don't realize you want until you have it, then you are annoyed if you don't have it.

Even under the best conditions, half a second is a bit of an exaggeration, and you're often not under the best of conditions. The cable slipped behind the desk, or you realize that you forgot to plug your phone in after you turned off the light or took off your glasses, or you're driving and don't want to be the asshole who causes an accident because you were fiddling with a cablet instead of keeping your eyes on the road, or your cable is getting dodgy and you keep forgetting to order a new one.

And then there is the annoyance of having your phone go dead because you were too tired to bother flipping the light back on, or never did hit a red light long enough to plug your phone in, or you jostled your phone and it stopped charging.

Is it a need? Certainly not. But it is damned handy.

I now have a Nexus 7 2013 (gave the 2012 version to my son who also has an N4 and wireless charger), and a Nexus 5. This is sort of a non-story for those of us who have been using Qi chargers for a year or more. Now I just plop the phone or tablet on a charging device. No bloody fiddling with the wire and the port and the glasses.

Not sure why a new charger from Google is big news. In addition to the original Google 'Orb' charger, the Verizon WCP-300, which is made by LG (who make the Nexus 4 and 5) works great. I've had one of those for months and like it a lot.

Wireless charging is very handy because I can just plop the phone down on it any time I'm at my desk. Without it I'd hesitate before using the normal charging cable, just to save fiddling with it and the wear and tear on the connector. And the phone stays more fully charged that way.

I had a Palm Pre (and have a Touchpad running CM10) and thats the one thing I really miss on my Samsung devices. I'm surprised its taken so long for this to catch on with other devices.

I found a few of the Touchstone wireless charging kits on eBay and modified them to fit a Nokia N900 with a double battery for four days of charge, this requires an extended battery door. I and my wife love them so much that it is still my everyday phone. I cant see an upgrade path I really like, unless the Neo900 pans out.

What Samsung device? You can toss a Qi receiver into a S3 or S4 (both have contacts for the receiver, but don't include it for whatever reason) for $20 or less.

Such convenience! Such charge! So wireless! This is TRULY stuff that matters!

There is nothing new about Google offering a wireless charger on their play store. This article is the equivalent of someone reporting that Amazon sells LED light bulbs.

This is Google PR piece. I see this guy posts google related stuff all over the place. Hey Slashdot if you keep posting such low quality pieces I will be giving up

Bug in 4.2 and 4.3 makes wireless charging useless (1)

Anonymous Coward | about 8 months ago | (#45482985)

I have a nexus 4. There is a wakelock bug that makes wireless charging for a number of these devices completely useless. Basically, the phone won't go into deep sleep mode while it's on the charger, so it burns just as much power as it gets from the charger.

See here: http://code.google.com/p/android/issues/detail?id=52034

I could, I guess, reboot my phone every time I lifted it off the wireless charger, but that's stupid.

Kit Kat is suppose to fix that. Google has begun distributing it over the air.

I know so many people with nexus and a broken power port (including myself). This sounds great! Much better than swapping out batteries all day.

I've got a Qi charger (1)

hamjudo (64140) | about 8 months ago | (#45483061)

It works even if my Nexus 5 is more than 5 mm above the charging pad. That is many orders of magnitude less than the range for most wireless communication technologies.

The useful features are

  1. no connector to wear out,
  2. alignment is simple.
  3. The USB/thinport connector is available for other uses. (More of a theoretical benefit, as I don't use the USB port for anything, but I could if I wanted to. I've got the cable, I could even plug in an SD card reader.)

If we had not ignored telsa (-1, Offtopic)

This wouldn't even be a topic for discussion.

Tesla, as brilliant as he was, was wrong about wireless power transmission (and a bunch of other things at the end of his life).

Maxwell's equations are settled science. You ether have unacceptable efficiencies, impractical antennas or zero range.

Re:If we had not ignored telsa (1)

RobertLTux (260313) | about 8 months ago | (#45483719)

except where he actually DID some intra city trials for wireless power.

i do think he cheated when he was using THE PLANET as a ground plane

Re:If we had not ignored telsa (0)

nurb432 (527695) | about 8 months ago | (#45484147)

He was wrong about the why, but not the how. All he lacked was continued funding to prove his concept on a large scale. ( on small scale, it worked fine ).

Sure, it wasn't as efficient as other methods, but it worked. Often times you trade efficiency for convenience in daily life.

Except for that previous Wireless Nexus Charger... (2)

mathimus1863 (1120437) | about 8 months ago | (#45483263)

Yeah, they had one before. I got it for my Nexus 4 six months ago. But there's a reason it got 1-2 stars: it's angled and doesn't hold the phone:

http://www.amazon.com/Google-Nexus-Wireless-Charger/dp/B00BGSPIP2 [amazon.com]

I almost threw it out but then discovered this 3D printed adapter [thingiverse.com] that actually fixed all of its flaws. It now works great, and it charges the phone fast when plugged into the wall! But since most people don't have a 3D printer, it makes sense they'd want to sweep the memory of that one under the carpet.

Re:Except for that previous Wireless Nexus Charger (1)

jo_ham (604554) | about 8 months ago | (#45483417)

That is a hilariously poorly designed charging device. What were they thinking when they stamped that one "ready for sale"? The one thing it has to do is support the phone while it charges and it simply... doesn't.

The 3D printed accessory is a neat solution though.

Other Qi chargers should work with the Nexus 5 (1)

hawguy (1600213) | about 8 months ago | (#45483339)

I bought a Nokia Qi charger cheap (~$20) a few months ago, but it didn't work well with my Nexus 4 - it charged it a few times, but mostly it would cycle between charge/no charge every few seconds. However, the Nokia charger works perfectly with my Nexus 5, I've been using it nightly for the past few weeks.

wireless chargers degrade your battery with heat? (0)

Anonymous Coward | about 8 months ago | (#45483433)

my Nexus 4 does get pretty warm using the wireless charger. reports indicated that the battery would degrade faster due to the high temperature, so i went back to wired. Any validity in that? Similar experiences?

What ever happened to pogo port charging? (4, Interesting)

hawguy (1600213) | about 8 months ago | (#45483505)

I don't really need wireless charging, I'd be happy to drop my phone into a dock with pogo port pins to allow easy charging without connecting a cable (and without wiggling the phone to get it to seat on a microUSB connector in the bottom of a dock). Seems like a cheaper and easier solution than wireless charging.

Why didn't more phones use that simple technology? I never did find a compatible dock for my CDMA Galaxy Nexus.

Re:What ever happened to pogo port charging? (1)

Michael Casavant (2876793) | about 8 months ago | (#45484093)

CDMA Galaxy Nexus...
All you had to do was get the GSM GNex car dock and so a VERY slight modification with a utility knife and then it works perfectly. Took me about 10 minutes...7 of those where watching a howto on Youtube.

I've had one for over a year (0)

Anonymous Coward | about 8 months ago | (#45483671)

Qi chargers have been on the market forever. I bought one when I got my Nexus 4 the day it came out. It works terribly, and takes forever to charge, and gets hot as fuck because inductive charging is so inefficient.

So much for being green.

It works fine on my Palm Pre and Touchpad. (0)

Not a new idea at all.

Power efficiency (4, Informative)

Jaktar (975138) | about 8 months ago | (#45483781)

I've checked a few places and it seems as though you can expect a 70% power efficiency with this type of inductive charger. Some of the higher end models reach as much as 85%.

It strikes me as odd that in a time where we want as much energy efficiency as possible, we'd push towards something much less efficient with the potential to be so widespread.
