I was hoping to start a little project on my N7. I love induction charging and want to set it up on my nexus 7. I was wondering if anyone who has gone through this/know about it/enjoy posting could give me some advice,
Most specifically:
Best dock+backcover combo
Thinnest coil plus chip
Fastest charging
Thanks in advance everybody, can't wait to hear your 2 cents!!

I haven't actually seen anybody fully implement inductive charging yet. However, this guy started doing inductive charging:
https://plus.google.com/u/0/101739011161245720271/posts/fAse7vGmc3q
Well, one easy way of doing it would be to buy a Qi standard inductive charger and a Qi standard inductive charging case (for example, the Palm Pre Touchstone case) and then pull the internals out of the donor case and fit them inside a Nexus 7 case. There's a small amount of soldering required and perhaps some fiddling with the fit, but the components are relatively simple and lay relatively flat. It wouldn't be too hard at all.
Unfortunately, I believe most current Qi charging solutions are relatively low amperage. This would make for a pretty slow charge on the power hungry Nexus 7. Not too bad it you're using it as an overnight charger, but nowhere near as fast as a 2 amp charger. It's possible that you'll find an inductive charger with a higher current output but if you're looking for that it might be easier to build one from scratch,
I did the Touchstone mod on my GNex. It only puts out .56 Amps. Their are kernels with "quick charge" that would let it ramp up to 1 amp but that was it. I am wanting to play with it too, but I'm more thinking of making a dock with POGO pins instead.
I gotta say, they touchstone is great for my GNex. I have a touchstone mounted in my car, so it holds it in place & charges. Occasionally the charge connection gets interrupted (hit a bump, etc...) and it takes 10 seconds to restart. I added additional stronger magnets to my case, but still I don't think the touchstone magnets would do very well holding a tablet instead.
Also, additional magnets screw with your compass...
the touchstone also has a strange angle for watching movies on the tablet.
also i dont know if you can make the induction work with 2amps like the asus charger. (which would be awsome for superfast charging)
If you used the pogo pins for this it would disable the audio if using the correct kernel (see my post in accessories). You would have to modify the kernel to disable it stopping speaker audio out (should be just commenting a few lines though).

The Touchstone is adjustable to whatever angle you want.
In short, could we slap a Qi-compliant coil in our Nexus 10, wire it to the battery, and win?
The coil itself is pretty thin from what I've seen, and there is a bit of room in-between the battery and back plastic (the people with creaky and buckling cases should know about this).
I don't know if there's an actual control board that is needed, but perhaps the coil could be hooked either directly to the battery, or even through USB (that way you can be notified of charging). If a control board is needed, then this might be a bit harder than expected, unless the board itself is pretty thin too.
It looks like someone's managed to do something similar to a Nexus 7 already and had good results (even enters docking mode): http://forum.xda-developers.com/showthread.php?t=2070851
Edit: Instead of routing the coil to the USB or battery directly, we could even hook it to the Pogo pin area, like the person did for the N7 coil mod above.
I'm willing to give this a try, but may have to wait a few weeks till I can get the funds for a coil and for it to ship to me.

According to a-post-at-techchrunch-i-cant-link-to-cause-im-a-noob, the Nexus 10 has Qi already... is it wrong? I haven't opened my Nexus 10 to check
I have openned up my Nexus 10 and dont remember anything for wireless charging being there.
I saw someone mod the Galaxy nexus to enable this sort of thing and from what I remember you should be right Espionage, just as simply as you think. And yes there is room to do it.

I can find no reference to the device on the offical Qi website. This makes me highly skeptical that Qi is already present on the N10, perhaps they confused it with the N4?
Search for yourself if you'd like: http://www.wirelesspowerconsortium.com/products
As slow as the Nexus 10 already charges with it's stock USB cable... do you really WANT to charge it with Qi? :laugh:
You might have to charge it for a week from 0% to get to 100%
Any further developments?
Hey Guys!
Is there any further developments on this possibility? :fingers-crossed:
Why not just use a pogo cable.... you would have to plug in a charging pad anyway.
Nexus 10 Wireless Charging Solution
I know it's been some time but I'm kind of surprized nobody posted a solution yet. I just had a Nexus 10 open and noticed not for the 1st time the pogo pins at the bottom that Google never even put to use. I can't even find an aftermarket docking station for it. We aren't talking about Apple here. Anyways the closest I've seen is a magnetic pogo pin charging adapter cable probably sold mostly to people who broke their USB ports. It seems nobody picked up on sewermike's comment. They DO have pogo pins and with a wireless coil (2-4 chained together) you could wire them to the + and - of the pogo pin cable easily. Also if you have access to old Nexus 2nd gen back covers you can get them there or on eBay cheap. It might be slow like TheAltruistic says but if you have a wireless device charging coffee table which I'm seeing more and more you can just set it on that. If I have time I'll do video or at least post my results.
ive got the pogo cable, if you can buy it do so - its well worth it, i think i paid £15 and i totally stand by it.
as for wireless charging, you can get wireless charging receiver cards that plug into the micro usb port, with this you can either plug it in and bend the cable around the tablet and hide it inside the case or plug it in and have it hang outside, you just rest the card on the charger.
please remember that is isnt a perfect solution as the card will get hot and overheat and stop charging or you'll spend all day charging the tablet.
i use to wirelessly charge the nexus 10 but id rather stick the pogo in
I ordered the official Samsung wireless cover from Amazon, slapped it on, and then put my Otterbox Commuter series over it - so far so good, everything fits reasonably well.
I go to put my S5 on a wireless charger and it charges. Then stops charging. Then starts charging again. Then stops again. Over and over it repeats this.
I get to thinking the phone is just too far away, so I take off the hardshell of the Otterbox Commuter. Same thing happens again. So I take off the soft shell - now I'm down to just the naked phone, and it's still charging on and off.
I'm using the blackberry folding blade wires, and the chargers found here: http://forum.xda-developers.com/goo...udget-wireless-charger-showdown-5-qi-t2676249
Specifically, the tilted charger and rectangle with LED lights. Both are giving me the exact same on & off problem.
So does anyone know how to fix this? Is it the chargers or something I'm doing? Are the chargers just not generating a strong enough field (if so, which charger can I get that will generate a better field?)
Thanks for any help
EDIT: Clarified that wireless cover is official Samsung

I had the same issue with a cheap receiver I bought off ebay. The receiver was junk. I took it out of the phone and dropped it on the mat and used a multimeter to check my voltages and never got consistent readings. Tried again with the same chinese mat and the official back and no issues at all.

I am having similar issues using a Palm wireless charger I custom made. I believe the issue is the connection from the cover to the pins on the device next to the battery. I am going to try adjusting it. Also, putting the phone in power saving mode before wireless charging seems to help. Think it may have to do with the wireless charging coil not providing enough amps for the phone to keep up. Trying a different cable/wall charger may help.

It could be the output isn't high enough. For the official mat you need to have a 3 amp charger for it to work. And if the output is too low, the phone may be getting confused because it is detecting a current, but not enough of one for it to be registering that it is charging. I have a car charger that has a 1 amp and a 2 amp setting, and when I try it on the 1 amp setting I get the same issue where it connects and disconnects. 2 amp and I get 0 issues.
I have a similar issue. I'm using the official Samsung S-View Wireless Charging Cover with the Nexus 5 wireless Charger. I get nothing when I put them together. I believe the output from the charger is around 2 amps and it works perfectly with my Nexus 5 (surprise, surprise...) Not sure why I don't get any response whatsoever...

I'm using a blackberry folding blade charger, the stated output is 1.8 amps, and my Samsung charger that came with the phone is 2.0 amps; both give me the on/off problem. Is 3 amps really the key? Where do you find one?

Sorry meant to say 2 amp. But you may want to test your mat and receiver and see if it really putting out the 1 amp the other thread said it was supposed to. If you are getting an output of less than 1 amp that the other thread says it should be then that is probably your issue. Unfortunately I'm not able to measure the outputs on either of my mats to give you an idea until later this evening when I get out of work.

I think you may be right; it may well be the mats I have are just junk, both of them, unfortunately.
I opened up the back of the phone, and brushed off the wireless charging prongs, just to make sure they weren't dirty. Put cover back on, put otterbox commuter case back on.
Put it on the wireless charger, it cycles on/off again and again, about once per second. Take off the hard shell, leaving just the soft shell, and it cycles on/off about once every five seconds - that is, the interval actually got longer. Take off the soft shell, down to a naked phone, and works after cycling on/off about 5 times, then it settles down and stops cycling.
On another charger, the tilted qi charger, it'll charge if the phone is naked, but if I put even the soft shell of the Otterbox Commuter on it, it'll cycle a few times then just not charge at all.
I'm not sure this is a connection problem with the prongs, or a problem with the wire/charger. I think it has something to do with the field that the qi charger is generating. Since I don't know jack about the qi standard, can anyone tell me if all qi fields are equal? That is, do higher quality qi chargers produce a larger or strong field than cheap units?
Like I said in the OP, these are all very cheap chargers, $15 at most, and I'm wondering if that may be the cause.

I use the 2A charger that came with the phone with the CHOETECH pads. The insert is the CHOETECH mat inside the cover. The pad is rated 2.1A input, 1A output. My phone cycles on-off occasionally when the phone hits 100%. I use the Otterbox Defender case.

Interesting, so could the problem be due to just using a cheap generic? Seems that the cheap ones may be generating a smaller or weaker field?
Just wanted to post an update - bought a more expensive charger, one with 3 coils instead of the 1 that was in my other two - and now it charges fine, right through my Otterbox Commuter case.
So to anyone else having this problem - the field generated doesn't seem to be big enough to penetrate the Otterbox Commuter with just one coil, you need 3 or so.
EDIT: Specifially, it was the Cheotech Qi wireless charger, rectangle with LED

it's not the problem with the coil, they give out the same current, it's because the angled charger is a cheap and nasty one, and the flat one is just a fake one, the official one cost alot more.
3 coils only give you a wider surface detection, the current is just the same as a single coil or a 7 coils.
The 3 coils charger you have is a rebadge of powerqi T300 which is a highly recommended one.

I am purchasing a Galaxy S5 next week and I am looking at the wireless chargers as that is the main reason I am upgrading my S3 in the first place. I have read that once placed on the charger the screen will read "wireless Charging" What I am wanting to know is if the phone is still on and if my wireless hotspot will continue to work in wireless charge mode?

I kind of thought the hotspot would still be active, on the other note I had no idea the s3 was wireless charging. does that mean all it needs is a pad to lie it on? Not sure if I understand?

Yes it will. Or at least it does for me, so I don't see any reason it wouldn't for you as well. Your hotspot range may be reduced during wireless charging due to the RF interference, but if you had a strong signal before hand then you should be fine..
.
I've noticed no loss in wifi, hotspot or 3g performance while wireless charging, and the S3 and S5 can both use the same charging pad because they both QI compatible.
~7 dB effective attenuation when wirelessly charging my S5

None of the S5 variants that I have seen will wirelessly charge by simply placing them on a charger. You need to add two things - the charger and a coil. The coil is the part that is inside the phone, a sort of receiver. The coil looks like a thick sticker and you can either buy an optional battery cover from Samsung that has a coil in it.. or add a third party coil to the inside of your existing battery cover. This is in contrast to say a Nexus phone where the coil is not optional - it is already built into all of the Nexus phones.
So it's odd to say that you are upgrading from a S3 to a S5 because of wireless charging.. when both the S3 and S5 need to have the same components added to add wireless charging. You seem to think that the coil is standard on S5's and it isn't.
Note that the optional Samsung wireless battery cover is thicker than the standard battery cover, which means that some cases will no longer fit your phone. And if you add a coil to the inside of the standard S5 battery cover, you need to choose a coil that is thin or you may displace the battery cover and lose the watertight seal.

Thanks for straightening that out for me. Now I understand. Yes I am upgrading from a s3. I knew nothing about wireless charging until recently. Guess I need to get my nose into these boards more often. I am a road warrior and ran into usb port issues on my s3 in Denver a few months ago. I panic because I couldn't charge my phone, so I went to the closest 3rd party phone repair store and they sold me an extra battery and a external charger. That worked great but the fact that I had to swap batteries 2-3 times a day, left my phone without a case, and you know what happened next. So since my upgrade is tomorrow, it's time for a new phone and I am excited for the s5 anyway. Thanks again for the help,:good:

No doubt you will love the S5. It's a significant upgrade from the S3, which was already a very good phone in it's own right. Enjoy

Has any one any experience with wireless charging on the Yotaphone 2? It supports the Qi standard but I've not ever had any device that can be charged wireless so I don't know what to expect.
There are some cheap chargers on ebay so I may get one to experiment with but wonder what others are using, how long a charge takes? is there a tiny sweet spot to get it to work? does it get hot? Any compatability issues?
Thanks

Hi there,
Yeah actually I got one for my YotaPhone 2, it's ADATA Elite CE700.
First I have to say I was very disappointed because apparently you can only wireless charging the YotaPhone2 with the main screen facing up! Also you should know that the spot where Qi located is a bit small (3cm in height in the middle of the EPD Screen), but that also depends on the type of wireless charger you would use. Something like Tylt Vu would Support more area thus its more hassle free.
It's also good to know that with wireless charging you won't get Quick Charging anymore. Because In order to do that you must use the MicroUSB port. But again how long a single charge takes depends the type of the Wireless Charger and the amount of output current it has which most of them are 1~1.5A.
For your last concern, any Qi Wireless Charger will do but try to get one of the Tylt Vu. It has the best reviews. And the phone won't get hot during wireless charging if you must know.
And something which I'm not sure whether its my wireless charger or it's general, is when the battery is 100% the charging won't stop, unlike the normal charging with dedicated adapter which cut the current when the charging is complete.

Hi, thanks for your detailed reply, I've now ordered two different generic chargers off amazon to experiment with, they are coming from China I think but were less than a tenner, I'll report back on these after ive used them for a bit.
It seems less than ideal for me to have to charge with the EPD facing down but I guess this is an engineering limitation. I'm sure there would be advantages and disadvantages of each side facing up during wireless charging.
I recently bought the Nokia DT903 wireless charging plate.
It works effortlessly with the Nexus 5. I can pick it up and place it back for charging with no connection worries.
With the Yotaphone 2 it does work, but it has to be in EXACTLY the right spot.... I'm talking millimetre precision here.... it becomes really frustrating to use and spoils one of the key benefits of wireless charging.
That's what is worrying me about Qi charging, I like the idea of wireless charging for the convenience, I work shifts and fiddling with the usb cable when I get in can disturb my partner, just being able to lay it on my night stand would be great, but sometimes I check the time on my phone in the middle of the night, or get up for the loo and nudge the charging cable and move the phone and if its really fussy about how it sits on the charger then I could end up with the phone not being charged overnight.
The ADATA Elite CE700 mentioned by Parisabs4 above looks like a good solution as it is adjustable and with the phone sitting on the cradle it is hopefully easier to hit the sweet spot.
QI charging experience
Okay so I've now tried 3 different Qi wireless charging plates and I have found that all of them exhibit the same problems whilst attempting to charge my Yotaphone 2
In the picture there are 2 single coil chargers and one triple coil charger (the one that is not flat) they are budget models, costing between £4 and £7 on Amazon.
I can get the Yotaphone to begin charging correctly on all three chargers, the phone says it is charging and the qi devices LED blinks to confirm charging. After 10 - 15 seconds the Yotaphone & chargers will stop charging, the indicators on the phone and charges indicate that charging has stopped. After a couple of seconds charging will recommence for about 15 seconds and the stop again, this cycle repeats for a few times then charging stops all together. Lifting the Yotaphone off and then returning to the charger will recommence charging.
My conclusions are that
My device has a faulty wireless charging receiver. (This is unlikely as im on my second device with the same symptoms after an RMA for a previous fault)
The charging software in the Yotaphone is buggy.
The Yotaphone is not fully compatible with the QI standard.
The Qi chargers I am using are not powerful enough for the Yotaphone. (Unlikely as I've now tried 3 different chargers but they were cheap!)
Has anyone else experienced this problem or is using a charger that is proving reliable?
I'm tempted to try the official wireless charging block as it ought to be compatible with the Yotaphone but its £40 wasted if not (although it can charge via a usb port too)
WHY IS NOTHONG EVER EASY IN THE TECH WORLD!!!!

As a footnote I have found my tablet charger (a 2.1amp samsung) works with one of my qi charging plates to charge the yotaphone but any other 2.1amp charger exhibits the same problems as the regular 1 amp chargers I've been trying to power the qi plates. Also I've discovered the Yotaphone will not charge from the usb socket in my car but any other device I connect to the socket charges fine, this is one flakey device!

I bought a cheap nameless one, have yet to receive it, I hope it will work in combination with a powerful adapter. Anyone got these cheap (5 USD) chargers working with their phone?
Another good QI charger for YP2 is/are the ones that IKEA sells. They have several models, but all seem based on the same platform powered by a 19V DC adapter.
I couldn't get any cheap QI chargers to work reliably with my YP2, but the IKEA chargers work great. They have some margin in positioning the phone on it, and prices start at around $30/EUR 25, so not to bad. I cannibalized the electronics from a JYSSEN to transplant them into a custom 3D printed charger case.
Does anyone have any experience using this Samsung 2A charger with the Yotaphone 2?

UPDATE: Never mind, I ended up buying the Nokia DT-900 since it's on the official list of supported chargers.
I bought my first wireless charger , a cheapo one from China just to see how they are. Cheap as in 4 USD. It does work but exhibits behaviour like described above. All night only charges it a little and the on light is not on much. I thought it was a problem with a cheap charger, but maybe not, it sounds like Yotaphone firmware. I don't have any problem finding the sweet spot.
I was reading about new LG fast charger that is coming out soon, first ever fast 15w wireless charger. But of course it will be expensive .

I bought an 3-coil-qi-charger-stand from China (eBay article 381639407985) about 10€. It works perfekt.
Cheap Single coil charger work also, but only if you place the Yotaphone at the exactly right position ( only 2mm tolerance). As the coil inside the 2,80€ single-chip-computers charger from China is often not places correctly inside the housing, you first have to correct that.
So tripple-coil is to be prefered.
One nice thing: Charging via QI and USB-OTG works fine at the same time on Yotaphone. You can put the Yotaphone 90 degree rotated on the 3-coil-charger-stand and watching Videos from a USB-Stick.
I even think about building an own small OTG-Adapter, using a extreme small micro-usb-connector (like used in universal QI reciver-plates), a very small USB-Micro-SD-Reader, some wire and epoxy. The SD-Reader will be placed on the lower frame of the ePaper. I use a bumper and would cut the neccassary space out of it. So I could build an nearly invissible (with bumper) SD-Card-slot. 64GB extra space is nice...
I'm using a Nokia DT-910 that I originally bought for my Nexus 5 a few years back.. works just fine with the YotaPhone 2..
No need to be careful with positioning or anything like that.. just put the phone on it and that's it.
The benefit of a charger like this is that you can actually see the screen while charging instead of it being flat on the table like some other models.

Never thought about it but they do seem quite common https://www.youtube.com/results?search_query=qi+wireless+powerbank
Or you can easily make one yourself by taping a wireless charger to a powerbank
In that case there is a wire, between PB and Wireless charger. �� so NOT wireLESS, lol
Can I use a QI Wireless power bank to charge the Yotaphone in my pocket?
Sometimes my phone runs out of juice. Is it possible to buy a power bank with wireless charging capabilities and use it to tirelessly charge my phone, by placing the power bank in my pocket next to my phone?
