I have moto 360 and while it lasts me all day since I don't have any portable qi chargers I'm afraid I'll run out of battery if I stay at someone's house or something.
So I was thinking, the nexus has qi as well, so could I make the nexus charge my moto 360?
I would charge my nexus through the many wired external batteries I have so the draw backs would be minimum if it's at all possible.

no. the n6 isnt a wireless charger. it can receive a charge, but cant give a charge.
Very helpful... , why not? The nexus 6 isn't a lot of things and yet we make it possible, what us stopping the nexus 6 from being able to do this?

Hardware limitations. It's not made to wirelessly output enough power to charge a device. Only enough to activate a NFC chip with a short blast to read/write.

NFC does not use the QI coil at all. Its totally separate.

By being physically designed to do so.
Anyway, its not possible and it cannot be made to be possible with software

It would need firmware and hardware modification. Yes you're right, it is not beyond the realms of possibility - on the other hand, this will not be happening.

USB OTG --> USB wire --> USB powered Qi charger?
Of course, the Nexus won't actually be outputting wireless charging, it will just be outputting power on the USB.
Note: Don't do this, it will drain the Nexus battery to accomplish not very much moto charging.
And for that matter, what does it matter if the WATCH runs dead if you have a PHONE in your pocket? Let it run dead!

well the idea was as a travel thing, i have tons of ways to recharge through a cable but not wirelessly, so i could keep the nexus charged but the watch would run dead, if i could charge the watch with the phone i could keep them both charged... i guess it might be simpler to buy a qi station for traveling, XDA has gotten too lazy/argumentative for this to happen :crying:

That is hard wired directly into the battery contacts on the motherboard or to USB pinsfor power input only. Output is a whole different story.

Lazy? No. Don't insult us.
Use logic please. It is not a sound idea to implement on the device.
You might get away with using OTG to power the stock charger for the 360, but it will not be able to charge much at all. The device can only push a max of 500 mah, but for a proper charge, the moto 360 needs at least 1 full amp.

That is interesting. When I had mine it said 1 amp output. However, it's still illogical because it would murder the phone battery. It's pointless to do because if you don't have your phone, your moto 360 is pretty much useless. I would suggest just getting a battery pack or a mobile qi charger.

Omg I literally explained this 3-4 replies back. I have plenty of wired recharging solutions for the phone just no wireless ones for the watch:
I have a wired external battery and 6-10 wired wall/car chargers to carry around. So I would charge a moto 360 with 20% battery left with a nexus 6 that has lets say 80% left. Doing so brings the watch to 90% and the nexus at 10% then I use my external battery or a wall/car charger to charge the nexus back up. Is that so hard to grasp? Quit questioning the reasoning behind it, if you don't think it can be done DON'T REPLY there is no need to bury the one guy who can do it in a sea of "that's a dumb idea" and "that's impossible". I already own ALL THIS STUFF I don't want to buy another just to charge the watch on the fly. These phones are general purpose devices. They should and could do everything given the right hardware and software modifications. We've powered computing capabilities of satellites with a nexus how hard can it be to give it qi output?!
For crying out loud some of the users here seem to be here only to denigrate those who ask questions and suggest ideas!

Hello everyone. I have recently bought new battery for my nexus 6 (Akku powercell).
After swapping battery to the new one phone doesn't want to power up (plugging in charger shows full battery icon and restarts. Additionally under charger I can access bootloader but the phone wont start/enter recovery - each try ends up in the charged battery icon loop).
Replacing the battery back with old one and everything works fine and dandy.
I've checked the new battery with a multimeter and it shows ~3,7V so should be charged enough to boot. Maybe anyone has an idea what could be the problem? Is it something related to me not getting new wireless charging coil along with new battery?
Should I try and misplace the wireless coil connection to motherboard on purpose (I'm not really using it anyway so not a big deal)?
Any help will be appreciated.

In case you used the standard quick charger....Use a different charger to charge the new battery for at least one hour. Maybe the new battery is not compatible with the N6 charger
In the LG Nexus 5 there is also an equal detail and the problem is that the center line of the battery is responsible for measuring the temperature of the battery and not making good contact with the motherboard the cell is immediately turned off to avoid damage , I would recommend that you check the centerline of the new battery

Its more like the phone doesn't see the battery. I can unplug its connection on the motherboard, plug in charger and have the exact same result like with it plugged in. Old battery works just fine, altough I can feel its age (accubattery shows around 75%).

Hmmm, could You maybe point me to the specific thread? I can't quite the understand what do You mean with the middle line.
And what country do You live in that You can't get a nexus 6 battery if I might ask? You could always order from china, or try searching for an ez30 battery - might pop up few local (country-wise) shops who might still have them.
I'm not saying it's your specific case but it could have something to do

I live in Ecuador and for the ridiculous tariffs and delays of the customs of this country it is a martyrdom to import that is why I can not easily get the battery of my Nexus 6 since mine is failing since 30% goes out
---------- Post added at 07:30 PM ---------- Previous post was at 07:26 PM ----------
In short the batteries of all the cell phones bring a temperature sensor, some batteries bring 3 contacts as in Nexus 5 that one is +, the other is GND or Negative and the middle line is from the temperature sensor of the battery, now in the Nexus 6 is 4 only that the additional line is sensor but separate, if the battery is placed and the cell phone does not read a temperature it automatically turns off to avoid equipment damage

Ah this way. Now I get it, thabks for the link too! And sorry to hear that : /, If You can manage to fit the other battery (is connector the same?) then the only hurdle might be the battery frame and putting backcover back on, but a decent case might accomodate for the backcover.
What I would recommend is that if you have voltage in the battery according to what I read before then the battery circuit if it would be worth, then with a needle try to close the pins or contacts of your new battery

Well, You are MVP dude , someone in that nexus 5thread mentioned trying to put something between case and battery connector, I cut a piece of business card, folded it in half, put it over the battery connector and a little under the frame and to my surprise, phone booted up! I can't say how grateful I am to You ! Picture attached for reference .

It's nice to know that you solved your problem

Friend what I would recommend is that the image you uploaded reference you delete or hide the imei numbering, sounds paranoid but it is not too much to prevent
So I just bought a pogo charger from ebay.
With it, I was able to bring back my nexus 10 that I once thought was dead for sure.
I think it's ridiculous that the nexus 10 didn't come with a Pogo charger,
even if the micro usb charger takes 10 years to go from 0 to 10%.
I don't have much knowledge on how to reverse engineer this, but I have tools and access to tools.
So my proposal is, if people can help me, we can create a DIY POGO charger for anyone who is still using this tablet, including myself.
I'll be using this post to post updates on it. Including pictures in the future.
I don't have much knowledge either, but am interested in the outcome. Thanks for posting this!

Seems it's symmetrical (which makes sense given that the charger works in either direction). So at any given point it's drawing voltage from just one of the two 5v pins (I'm not technical so I also have no idea what I'm talking about).

I've seen the first post, but I haven't seen the second. It's good to confirm both posts says the same thing.
I'll disect my charger in the future and post what it looks like, so we can make a block diagram for it.
If you ever get one created I would like to purchase one for my nexus 10 tablet. [email protected]
I bought a new battery. I have been using it for 1 year, it won't charge and the tablet won't turn on
I'm wondering if anyone knows if the S10 will be able to charge a watch that is NOT Samsung, for example Huawei or Moto? Thoughts?
I'm not sure but I seen flossy carter charge his iphone off it so my guess is that if the watch supports wireless charging it should work.
Any ideas at what speed(s) the charging is capable of?
