[Nexus 7 (2013) Q&A] nickfuzz:
I had the same problem. My Nexus 4 works perfectly with the WCP-300 charger, but the Nexus 7-2 wouldn't charge at all with either of my two WCP-300 chargers. This morning I exchanged the N7-2 at Best Buy and the wireless charging now works. The WCP-charger is a little tricky, perhaps due to it's small size. For example, the charger must contact the center of the device, and you have to set the charger there for a second or two before it starts charging. My N4, on the other hand, starts charging as soon as I place it on the charger. Actually, the WCP-300 charger works nicely because the N7-2 balances perfected while charging. So as long as I place the device so it balances on the small charger, it starts charging.

Anyway, I had some awesome luck at Best Buy because someone called to cancel their Chromecast order while I was completing the N7-2 exchange. A rep brought the Chromecast from the back and I asked if I could buy it. They also sent me a code for the 3 free months of Netflix.

Perhaps you have bad luck. I can confirm my first N7-2 device didn't work, so there must be more out there. Try centering the WCP-300 and holding it there for a few seconds. If that doesn't work, I would try for another exchange.

Swapped mine out at BestBuy today and wireless charging works flawlessly now. Made them open it up and test it before I left the store (brought Nexus 4 Charging Orb with me).

For the ones that wireless charging isn't working, is NFC working for you? I may have to swap it out at Best Buy today.

Ditto here too. If the display is off when I place it on the charging pad, the display turns on and does not turn off. I have to it the power to turn it off, little annoying.

[Nexus 7 (2013) Q&A] imstill@g:
I've tried both, along with 1.2 on 2 orbs and 1 LGW300... ON TWO NEXUS 7... I cant believe I am having this kind of luck

As for NFC, yes it works flawlessly on the one I currently have. I have 15 days to return it, Ill be out of town for a week, Ill wait to see if Walmart gets another batch in, being that 2 out of the three they have are not working. I mean I would assume something had to be wrong with my chargers if I were not charging two other devices with all three of them...
[Nexus 7 (2013) Q&A] darkjedi:
Exchanged it at Best Buy. Brought my charger along to make sure it was working. Working just fine now. :)
[Nexus 7 (2013) Q&A] CallMeTut:
I tried using the fatboy yesterday after first getting the Nexus 7 but couldn't get it to charge (as a real newbie I didn't know it had qi abilities until after reading the specs (after purchasing)) fatboy works great on my wifes dna, but the Nexus didn't seem to see it. I may have been moving it around too much trying to find the sweet spot. The qi location on the tablet is about dead center... correct?

I have a Nokia DT-900 Wireless Charging Plate and a Nexus Charging Orb, and the N7 charges perfectly with both of them.

---------- Post added at 04:54 AM ---------- Previous post was at 04:53 AM ----------

Neither do most places, the only one I could see caring is Google, and even then it's a toss up. I would bet they wipe and reload the OS and Apps before reselling them anyway, at least they are supposed to.
[Nexus 7 (2013) Q&A] BoneXDA:
How fast is wireless charging, and BTW how fast is USB charging?
[Nexus 7 (2013) Q&A] :
There isn't really a rating of fast. It charges just as well as cabled charger cord but some energy is lost as heat in the inductive coiling. So really, the received energy is just a little less than the rated output on the Qi charger... and basically just as good as a cabled charger.
[Nexus 7 (2013) Q&A] tkdsl:
Fixed my wireless charging problem (Connectors were not clean)

Ok so I will start by saying that the fix is on the Hardware side.

I purchased the new N7 32g mode from Best Buy but wireless charging did not.

I wanted to return the device and get another one and since it just came out, you could not get it anywhere.

so after I saw how easy it is to open it I decided to open the case and check the connectors and they looked like they had something on them.

So I cleaned them with my finger and closed the case again and the wireless charging is working now.

now be very careful if you want to try this, because the guys at IFIXIT cracked the outer shell when they did it.

no damage on mine.

so if you want to take the risk you can try my fix. now I do not have to exchange it.

Hit the Thanks button if this post helped you.
[Nexus 7 (2013) Q&A] junkinmytrunk426:
damn just bought a qi charger(nokia dt-900) to test mine out and of course it doesnt charge...without anymore in stock, its gonna be a pain to exchange.

---------- Post added at 06:18 PM ---------- Previous post was at 05:23 PM ----------

Thanks for the tip! wiping the connectors fixed it for me. by any chance did yours have a bunch of finger prints inside? mine did and i think thats what gunked up the connectors.
[Nexus 7 (2013) Q&A] tkdsl:
yes it did. and it is was a simple fix, but takes nerves to open a brand new unit.

glad it worked for you.
[Nexus 7 (2013) Q&A] :
What tools did you use to open the unit? Spudger? Suction cup? Where did you apply them on the casing? Thank you in advance!!
[Nexus 7 (2013) Q&A] junkinmytrunk426:

[Nexus 7 (2013) Q&A] DanielNTX:
Yes same problem with mine. Qi Charging did not work and neither did the NFC, although it did on the first day. Opened it up and cleaned off the gunk off the four contacts and Qi and NFC started working again.
[Nexus 7 (2013) Q&A] :
Thanks. I can also confirm that this worked for me; I just opened mine up, polished the gold contacts ( I couldn't see much in terms of contaminants, so clean anyway if you ware doing the same) with very small, small amount of rubbing alcohol, then closed her up and tried again. Voila, Qi charging works.

Thanks guys!
[Nexus 7 (2013) Q&A] junkinmytrunk426:
did either of you guys notice a bunch of finger prints inside your tablets?
[Nexus 7 (2013) Q&A] :
I sure did; they were a bit blackish in color. That's nothing to be worried about (although those assemblers should be using gloves in my opinion). I used a microfiber cloth on the fingerprints and they wouldn't really be picked up. I didn't try any rubbing alcohol on them though, just the cloth.
[Nexus 7 (2013) Q&A] osetivo:
Would two N7s fit?
[Nexus 7 (2013) Q&A] littleguevara:
No unfortunately not, it's awkward enough to get one lined up. Id say one takes up just enough space so that you cannot fit another N7 on there. You could fit an N4 though ?

Mine was not working with the n4 charger, soon as I cleaned off the tabs on the back cover it worked like a charm.
[Nexus 7 (2013) Q&A] Jayrod1980:
Wish I would have read this before I returned my first tablet. It was great other than the wireless charging not working. The second one is fine. I was more concerned though that the device would get creaky or something after breaking it open. Ifixit cracked their case opening it... Did you have any problems opening it?
[Nexus 7 (2013) Q&A] DanielNTX:
The case is brittle. I put a hairline crack in at the headphone port.
[Nexus 7 (2013) Q&A] darb:
Yea I stressed the back where the headphone jack was as well

I ordered the Samsung wireless charger.. I'm getting it next week but hopefully it will work.. Fingers crossed
[Nexus 7 (2013) Q&A] LGSilva:
My NFC and wireless charging were not working, so I opened the n7 and the contacts looked clean. I lifted the other contacts on the circuit board and now it's working fine.
[Nexus 7 (2013) Q&A] :
The case is indeed brittle. Its a lot thinner and malleable than you would expect. The innards of the case and the excellent build tolerances keep it from feeling negative in any way. And that's a good thing. However, to open it, I suggest you use a spudger like ifixit did and check out their photos so you know where to separate the casing from the rest. Also be sure to go all the way around to disconnect the mini retaining clips. You're more liable to bend or break or warp the casing if you do just two or thee sides and pry the last one off. Easier to loosen all four and lift the display assembly out.

I was lucky and got no breaks fractures or creaks afterward.

Software solution to the Qi Charging Woes?

It kinda runs contrary to what people are saying on this thread (that it's a hardware issue) but I was able to solve my Qi charging problem on my new nexus 7 via a software fix that google support recommended. My NFC worked prior to this, but the Qi charging didn't work at all.

I don't really understand why this would work unless the units that can't do Qi Charging properly for some reason aren't flashing the new bootloader which supports Qi charging after upgrading to android 4.3, or perhaps I never tried rebooting after I applied the last android update? Not sure, but here are the steps that worked for me:

1. Plug the unit into USB power; wait for the unit to start charging

2. Power down the unit

3. Hold down Power + Down Arrow

4. Wait for the surgery android screen to appear

5. Use the arrow keys to select 'Restart bootloader'

6. Hit the power button to select

7. System will restart back to the surgery android screen

8. Select 'Start' and hit the power button to select

9. System boots, and qi charging seems to work

Ofcourse it's also possible the gunk on the pins that everybody says is making the Qi charging not work evaporated over the last 24 hours. But I figure it's worth a try for anybody else who finds this thread and is tempted to throw their nexus through a window.
[Nexus 7 (2013) Q&A] sfhub:
I tried this but it didn't make a difference. NFC always worked on this unit also.

Was there a point where I was supposed to remove the USB cable? I didn't until after the last step.

I'll find out morrow when I get mine in from UPS. Going to give one of these a try after I read a reviewer on AZ who said his worked perfect on his in landscape mode. I got it for 28$ w/ my AT&T discount. If it works gold,if not I have a expensive nightstand stand.

Thank you for posting this. I bought an LG Qi charger at vzw today since I get 25% with my plan so it was only $30. I was all excited to try this out. Got home, put the nexus 7 on the pad and it didn't do anything. I thought I was going to have to go exchange the tablet at best buy, which I didn't really want to do because other than the odd GPS behavior it seems to be working flawlessly. Well, I gave your "fix" a try and sure enough it works now.

I tried the procedure multiple times removing the USB cable at various points but couldn't get the Qi charging working. I'm guessing there are potentially more than one issue affecting Qi charging, with the software issue being resolved through your procedure but not the gunk on the leads issue, which requires physical cleanup.

N7 Inductive charging fix (for me at least)

Have a 32GB N7 and here's my story. Have been through 3 16GB units that had the "Freeze & reboot" issue but inductive charging worked fine on them. Since I had so many issues, Staples swapped me for a 32GB unit that has not exhibited "Freeze & reboot" for 4 days now (keeping fingers & toes crossed) but the wireless (inductive) charging was non functional on any charger. Took my N7 back to Staples and the Easy Tech associate let me try it on my charger, not charging, their charger, not charging & he even got another new 32GB N7 to try... not charging. He also brought a 16GB N7 along (one of my returns no doubt) and it charges. Since that was the only other 32GB unit they had I said that I would keep my current 32GB N7 for now. Decide that the only way that this will be fixed is if I take matters into my own hands. Off with the back cover of my new N7 :eek: no damage if you do it right. Checked all of the contacts for "Gunk", none seen. Cleaned contacts with isopropyl alcohol just to be on the safe side. Put back on the N7 and... still no wireless charging. Removed back again (Second time back comes off easier than first) Noticed that there is quite a bit of padding around the contacts presumably to alleviate the chance of noise from the back. I also noticed that the 4 contacts did not extend above the level of the foam padding. Using a 2.0mm slotted screwdriver I gently extended the 4 contacts just above the level of the foam padding. Snap back on again and... voilà inductive charging is up and running. :D YMMV and there is substantial risk involved with this procedure but it worked for me. Hope this helps!!

Update: Added photos of the rear cover contacts and the contact pins. The 4 pins on the board are at the arrows.

My device was working for awhile, and suddenly today, it stopped working. I didn't drop it, so I don't think anything dislodged.

[Nexus 7 (2013) Q&A] nickfuzz:
Thanks for the awesome post! My first N7-2 wouldn't charge wirelessly with any charger, so I had it swapped out at Best Buy for another. After two weeks of successful wireless charging, the second N7-2 stopped charging. Rebooting the bootloader did not help.

After reading this thread I decided to open the casing and check the contacts for debris, gunk, or fingerprints. I successfully removed the back with using only my thumbnail. I made sure to first loosen all 4 sides of the casing and successfully removed with no cracks.

Upon examination of the 4 contacts, there was no gunk or fingerprints. I cleaned the contacts anyway with rubbing alcohol and used a small flathead screwdriver to lift the 4 contacts off the circuit board. The 4 contacts are a bit "springy," which makes it easy to lift them so they have better contact with the electrodes on the casing.

After snapping the casing back the N7-2 wireless charging works perfectly.

Thanks again!

Asus has poor quality and servicr. You even need to open the case and repair yourself.

I changed at bestbuy, charged with Nokia dt-900, it's very slow, 10 hours for 70%. After full, it will not stop charging, will this damage the battery?
[Nexus 7 (2013) Q&A] indianajonze:
when the battery reaches full charge, the dt-900 switches to a trickle charge to keep it topped off. that's by design so that it doesn't damage the battery and you're always at 100%

If dt-900 at trickle charge, the light should be long blink, bit it doesn't for nexus 7. After full charged, the light still on.

[Nexus 7 (2013) Q&A] stvmac11:
Thank you for this! I did this on my second device (after 1st return).

The only problem I had was that half the tabs that hold it closed broke off, although I did have to remove the back cover twice.
[Nexus 7 (2013) Q&A] random_n:
I had the unclean contacts issue on mine, but everything else is working perfectly (admittedly, I haven't tried GPS yet, but I don't need it). NFC worked, but wireless charging didn't. I used a nice, soft guitar pick to open the case with no damage, fractures or creaking after reassembly. I did as others in this thread have said and worked gently around the entire case (started on the long edges, ended at the USB port) and pulled up from the side opposite the USB port. Isopropyl alcohol and q-tips cleaned it up well and charging worked immediately after reassembly. I went very slowly, and the whole process took about 10 minutes total.

I'm using a knockoff orb charger (link if you're interested) since the official one is double the price where I am. Note that while it does actually say LG Electronics on the bottom, the internal circuitry only bears a passing resemblance to the official charger (I took mine apart to add more weight and also found some photos of an official charger teardown). It's awful with my Nexus 4 as it stops charging at 100%, goes into some sort of standby mode where LED on the charger changes from green to blue, and then proceeds to keep the Nexus 4 awake causing rapid battery drain and it never charges again without remounting it. The dmesg logs are full of log entries from the wlc driver waking the device every second while this is happening and suspend_backoff is blamed in BetterBatteryStats. Also, the phone slides off fairly easily both with and without my dbrand vinyl.

However, on the Nexus 7, the knockoff orb works perfectly, holds the tablet securely and is pretty forgiving in positioning. The charger never goes to the blue LED status, the battery stays topped up, and there is minimal heat dissipation both while charging and while idling at 100% battery. It would work very well if you want to use the N7 with a daydream, but otherwise I would still recommend using a flat charger for the best reliability.
