Hello everyone. I've been considering a purchase of the Nexus 9 and was disappointed to to read that it lacks Qi wireless charging built-in. I've found Qi to be a very useful feature for many of my Nexus devices, from my old Nexus 4 and 7 to the modern N6, so it seems odd for it to be omitted for the N9. Thus,, if I end up buying a N9, I'll be interested in adding Qi charging capability.
Qi charging receivers seem to come in two forms: those that use the external micro-USB connector on your device and those that don't. Those using the microUSB connector have the obvious drawback of "taking up" said connector as well as possible issues with the detection of wireless charging , so I'd ideally like to use one of the models that doesn't use the micro-USB plug. These models (such as some of those made for the Samsung Galaxy S4 and S5) are completely internal and interface with the battery via other connection points, typically residing under the back cover of the device. An example can be seen here - http://www.fonesalesman.com/collections/qi-wireless-receivers/products/s5-slimpwrcard . I am guessing the viability/ease of install for such a receiver is dependent on the device model, so I was wondering if anyone had performed a similar modification on their Nexus 9?
Any ideas? Thanks!
So the Samsung phones were designed this way so they could sell you a separate case to add wireless charging. So it was designed to add it easily... I've seen something like this added to a non Samsung phone but it required some soldering and I'm sure lots of skill. I agree with you that qi charging seriously should have been in the tablet. At the very least some form of quick charging. My least favorite part of the tablet.

I just bought this phone and I wonder has anyone tried any internal qi charging receiver tag for it?
I'm sure they should work just fine, however, there isn't any tag built to the dimension of the Infuse, I just need to make sure the gold contacts location matches and it fit correctly in the phone.
It look like the receiver for the S4 i9500 may work. http://www.ebay.com/itm/Qi-Wireless...Samsung-Galaxy-S3-S4-Note2-Note-/231124647518
theres no wireless charging pins on the infuse. you can not use it with wireless charging unless you rig something to go to the microusb port.

The i997 doesn't have wireless charging ports built in like the S3, S4, GN2 or GN3.
Seems like one would need to create a terminal for the receiver.
These two videos show similar wireless charging hack for the i9000. The i997 is similar to the i9000. It looks like the idea is to get a wire from the + pin on the USB port to the back of the battery to connect the copper coil receiver complex.
For the qi, I think you can use any of the receiver available, minding the +/- connectors.
I have not tried it but it does look interesting. The other question I have is whether or not simply connect the +/- on the wireless receiver to the battery's +/- connector will work. It would be simpler to use some copper tape and connect it directly to the battery terminals. If it does work, obviously you can save a lot of hassle bypassing soldering the wire part.
Does the N5 have a 11 pin USB connector? If so, do you think it might work with the Samsung Smart Dock accessory? I'm aware that I can use SlimPort to perform a similar function but there is not enough charge current to sustain long usage.

It seems like 5 pin connector

I have nexus 5 and by looking at the USB port it seems like it has only 5 pins and probably there are no pins on the other side of the plastic. Can not tell with 100% confidence unless I open apart my whole phone. But my friend has Galaxy S4 and looking at the top side of the Galaxy S4 I there is a small dent on the top side of the port whereas there is no such dent in Nexus 5 port so it seems that Galaxy S4 port in non standard but Nexus 5 is standard probably only have 5 pins. If this is correctly sadly we can not enjoy features like Samsung Smart Dock on Nexus 5. At the moment I am trying to achieve using Game Pad and Charging the Phone concurrently on Nexus 5 but probably it is not possible may be possible with some special Kernel, there is one such kernel for Nexus 7.
Hello All,
I'm a new owner of a Galaxy S6 Edge, coming from a S4.
I had a Samsung multimedia dock for my S4, that had 3 USB ports, a HDMI Out port and a 3.5mm audio Out port. I purchased a wireless keyboard / track pad and plugged it into one of the USB ports on the dock to make typing texts & navigating the phone easier while at my desk.
Unfortunately, the male micro-USB plug on the Samsung multimedia dock does not fit the micro-USB port on my S6, rendering my wireless USB keyboard useless.
I've looked all over the internet and can't seem to find a similar docking station for the S6. Does anyone know of a docking station that has USB ports that will work with my USB wireless dongle & keyboard?
Much appreciated!
Hi,
Thanks for your report. It seems strange to me that the S6 micro USB port is different, should be the same old 11 pin that the Samsung used. Stupid question, but did you try inserting it the other way around, with the phone back facing you?
For your exact problem, with the keyboard, I assume the old USB On The Go adapter will work on S6, same as it does on S4, S3, Note2, etc. It's this one: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-R205UBEGSTA .
There's also a HDMI adapter, http://www.samsung.com/de/consumer/mobile-devices/accessories/connectivity/EE-HN910FWEGWW. Maybe those 2 can be combined, instead of using the dock.

Thanks for the reply!
Way ahead of ya on making sure the micro-USB plug on the docking station is facing the right direction. I tried docking it backwards and the plug n' port absolutely do not fit that way. It's facing the right direction, just that the port on the S6 is not able to accept the plug on the docking station....despite both being Micro-USB. I did notice, however, that the plug on the docking station had two small grooves indented in it, that looked different than any other standard micro-USB cable plug. It could be that those indentions made the device proprietary to the Samsung range of phones that released during the S3 / S4 years (including the Note 2 & 3). If you look at the compatibility of that docking station on Samsung's website, you'll notice that only the S3, S4, Note 2 & Note 3 come up.
I suppose the USB dongle you linked could work, but reading the device laying down flat, while trying to type on the keyboard might be problematic. You'd think that someone would make a universal micro-USB docking station with USB ports...but I haven't been able to find it.
I'm pretty sure the S6 no longer supports MHL which probably explains why the dock doesn't work either.
You can still go USB OTG, which should let you use your keyboard and trackpad mouse devices.

Interesting.....so are you saying that the micro-USB male plug on the Samsung docking station also had MHL connectivity integrated in it, which is why it's form factor is slightly different than a standard micro-USB plug?
The only times I've ever seen a MHL port on mobile devices was as a separate, similar looking, but different port than the micro-USB port.
I supposed all the wireless mirroring tech out now makes including hardware mirroring functionality not needed.

That's correct, it has to since it offers an HDMI out on the dock.

You're also probably right in your assumption that MHL isn't really needed anymore due to the widespread wireless screen mirroring technologies.
Hello everyone! Sorry for the dumb question, but I was wondering if it is possible to add a wireless charging receiver inside a OnePlus 6. There are some receivers on Amazon for Galaxy S3, S4 and S5, and I thought that it would have been cool to have one, just to play with the hardware.
I'm not talking about the receivers which have the cable with the Type C USB port, but the receivers that connect directly to the battery. Something we can build ourselves.
Could it be possible? What do you think?
I'd nearly say hold on for the 6t and save yourself the hassle. ?

Unluckly I have already bought the 6, and this is my first OP phone and i think it is just awesome.
Anyway I only wanted to do something cool and play with the hardware of my phone.
Yes, I use one. Works just fine. The only annoying part is having to unplug it when I need to connect to my PC. I wish they made one that plugs into the usb-c port but still allowed a USB-c to plug into the receiver. It would probably make the receiver plug too big.
Here is the one I use:

If you're talking about some kind of hardware hack, I can't imagine that there's room inside the case given how thin this phone is. Years ago, I tried doing something like that with my HTC One XL, which had a flexible plastic case and more room inside. I still couldn't make it work.
Wireless charging is awesome but i only like it because my phone has a micro usb.... now that i have ordered a oneplus with usb c i dont think i will miss it because wireless charging is slower and heats up the phone more.
You have two options, buy external wireless charging receiver that plugs into USB or do a hardware hack and put wireless receiver inside the phone. It's certainly possible as back cover is glass, but it's not trivial.
I picked up a Lenovo Tab M8 from walmart (Part number: ZA5C0045US). It comes with a small dock that charges the table via a two pin connector.
I was trying to set this up with an OTG cable so that I can attach a high end sound card. I notice that once I plug the OTG cable, the tablet stops charging via the dock. It's like OTG and charging is not allowed at the same time.
I also tried making my own OTG + charging cable (with a 10K resistor between the ID pin and ground), but it seems that the OTG function will not work unless the ID pin is grounded. I know that other devices allow for OTG + charging when the ID pin has a resistor to ground with a certain value.
Is there a way of finding out if lenovo tablets allow this? If so, where can I go an find out what type of resistor value this tablet will detect as allowing the function of OTG + charging?
Also, this tablet is rooted. Is there a software based solution like my old Nexus 7 (2013) where you could enable OTG + charging?
I've been at this for a couple of days now, so any help is greatly appreciated.
Hi,
Have you had any progress on this? I would like the same function.
Doing some reading though. I think a 10k resistor is too low, normally seen 64k or 100k
Hi, I just signed up to leave a reply here. I also was looking for a replacement for my slightly outdated Nexus 2013 in my car and stumbled upon this thread. So got a used M8 (TB 8505F ZA5G0038SE) and gave it a try.
With a 10k (measured 9.8k) resistor between ID pin and ground, OTG and charge works perfectly, without changing anything in software. With a 2A charger, battery charging is pretty slow, but the battery doesn't drain while using navigation and music (contrary to the Nexus )
So, for me it is a quite good solution.
Thank you for the info guys
I also have a TB 8505F and needed this function in my car.
For me the 10K resistor works, now it both charges and I can use my accessory (OBD2 reader)
Before this I tried a 100K resistor and that did not work so I had started to give up.
Just an update, maybe someone needs the info: I tried to make a second Y-OTG-cable with the same components, and it didn't work. Charging went on and off, no otg function. I decided to play again with the resistor values and it worked again with 12.9k. Maybe there is a certain range, which the second cable was slightly out of.
Hi All, i just bought the same tablet for similar purpose and i was wondering if when the cable is built using the 10k-12.9k resistor, i can still use the docking station that it comes with>? has anyone tried it out like this?
