I bought 2 of the Nokia Wireless Charging Plate DT-900s and all was well and good Thursday night. I left my nexus 4 on over night and it charged fine. Friday night, however, different story. I woke up to a dead phone. Thinking it slipped or something, I thought nothing of it. Saturday night I heard the connect notification followed by the 14% notification for about 3 mins and Sunday I woke up to a mostly dead phone. Last night and today I have tried placing my nexus 4 on there in different orientations and swapped both chargers out to no luck. I put my nexus 7 (2013) and it stayed connected for 10 mins without issue. Is there anything I can do to my nexus 4, outside of a factory reset, that would be a good troubleshooting step? As always, any and all help and information is greatly appreciated. Thank you.

i would also like some information on this subject. i have a DT-900 from my 920 and it disconnects and reconnects constantly. i thought about returning my n4 back to complete stock but i was wanting to see if this would help before trying it.
You have to fine a sweet spot . I had mine nexus 4 charge and stop but I played around with the position and found on that works great. Maybe a weak QI receiver BC I had no issuse using my lumia 920

Apparently only revision 12 and higher Nexus 4 devices work well with all Qi chargers. Unforrunately, I have an r11 device and bought three of these Nokia chargers. One worked for an evening, another worked off and on, and the third one hasn't been opened yet.
Guess I'll keep it plugged in. Maybe the N5's wireless charging will allow use of these chargers.
I'm having the same issue with the same Nokia wireless qi charger - sometimes it works great, mostly not.
The N4 registers a connection with the audio tone, the white charger LED lights, the charging icon on the N4 shows it is taking a charge, but nothing (much) happens - maybe a slight charge but nothing significant. The battery usage screen shows the phone has been connected and has received a continuous charge.
The fix seems to be to reboot the phone. Then everything works as expected. But that defeats the purpose of having a wireless charger on my desk - I just want to be able to pick up the phone, use it and put it back without worrying if it is going to charge or not.
This is so frustrating. I charge my phone by USB at night so it's not a deal breaker but wondering if this is a recent issue (I have only had my N4 for 3 weeks).
EDIT: just confirmed I have a Rev 11 N4. So is this a known issue? Reason to RMA?

I bought the DT-900 earlier on this week assuming it would work as it's QI compatible but have heard stories on here of people getting issues.
Should I just send it back without bothering to open the package?

From what i heard is that Nokia wireless chargers cannot be used by android devices and in some cases may even be hazardous to your phone.
I wouldn`t try it myself.
-Edit- It seems the 4.2.2 update made it compatible, look here http://forum.xda-developers.com/showthread.php?p=38019440#post38019440.
Thanks I'll test it tonight then and report back if I have any issues.
I have one and it works okay. The charging light on the charger stays constantly lit with the phone on it but the charging text on the phone will cut on and off for about a minute then eventually become steady. I also found that the position of the phone on the charger is critical, I place mine so that about an inch of the bottom of the charger is still visible. It doesn't work so well if the phone is directly centered on the device. It would give me a 30% boost in about an hour so its working okay. I was using it everyday for two months so I don't know where people come off saying it will damage your phone especially when they don't even own it. I had to stop using it as I put a Ringke case on it and you can't charge thru it.
Edit; I took the case off and it seems to be charging better since I update to 4.2.2. It will now lock onto charging almost immediately even centered.
That's good to know. I'm quite looking forward to using it now.
Will report my findings tomorrow.
Right just to confirm, it's working fine for me. Yes the charging text flickers on and off a few times but the phone eventually settled down nicely.
Got the charger on my desk. Really loving this phone even more now!

I have a nexus 4 that i just gave to my gf because i got a nexus 5. First i ordered a cheap qi charger on ebay that worked for awhile but after i returned the n4 to stock it wouldn't work...it would recognize the charger but would give a blinking light "error" on the charger. So I then bought a nice Nokia dt900 charger off ebay for the both of us thinking that the cheap ebay one from china was junk. Well its the same problem. My nexus 5 works great on the charger but the N4 wont charge. Like I said it recognizes the charger and the symbol on the battery (bolt) will go on and off every 5 or 10 seconds.
Anyone else have this issue?
It's finicky. The sweet spot is below center. I leave 1/4 inch of my dt900 exposed below the phone and it's always charged by morning. It does do some blinking but it gets the job done.

its def something wrong, cuz neither one will charge it right. But i have no idea how i would fix it. I dont see how it could be software especially being on stock 4.3
Update: Now its charging fine on the cheap ebay one but keeps going back and forth between charging and not charging on the nokia dt900. The nexus 5 charges perfectly on the nokia...i dont get it
The past two days, I awoke to find my N10, on the pogo charger overnight, at significantly less than 100% charge. First time, I had left it on while it charged and it was in the 70% range. Today, having been off all night and on the charger for 7 hours, the charge only went from 50% to 86%.
The really disturbing thing is the discharge rate. I've only had it on for 25 minutes or so this morning and it's down to 78%. The battery system settings area shows 57% screen followed by Dolphin at 7%. That plus the fact that it won't charge fully overnight, even when powered off, seems to eliminate a misbehaving app as the cause.
Since this behavior matches what I saw when my iPhone 3GS battery was about to fail, I'm guessing that's what I'm seeing here. And, of course, I'm 10 days past the 1 year warranty (purchased at launch), so I'm probably on the hook to fix this myself.
I'll try turning it off and charging it via USB during the day today, just to eliminate the pogo charger as the cause.
Just thought I'd see if anyone else had seen this behavior and if it's definitely the battery/charging HW or if there might be some sort of Android SW glitch involved.

You need to provide more info in order to properly troubleshoot. What version of Android are you running? Stock or custom ROM? Custom Kernel? Have you made any significant changes to your Nexus 10 since you've noticed the problem, ie. Did the problem begin since a recent update?
Sorry, forgot to add those details.
I'm on 4.3 stock. Boot loader has been unlocked, but the tablet isn't currently rooted. It was about a year ago, but an OTA unrooted it and I never got around to re-rooting.
No significant changes preceded this issue.
It looks like the 4.4 OTA just downloaded, but I'll hold off on installing it until I get this figured out.

It may be worth your while to try the update to 4.4. Some users have reported faster charging times and if it is a hardware issue there wouldn't be much you can do anyway.
I actually had a strange charging issue a couple of months ago which I thought was hardware related but after a full wipe and a clean ROM flash the problem resolved itself.
Last night, I tried using my Galaxy Nexus AC adapter & USB cable in place of the N10 adapter and Magnector and...it worked. The battery showed 100% charge when I booted the tablet this morning. The battery still seems to discharge more rapidly than I'd like, but at least it got to 100%.
I'll try the Magnector on the GNex adapter tonight and, if necessary, a USB cable on the N10 adapter tomorrow night to try to isolate the cause.

Bummer. Looks like the problem is either the Magnector or the Pogo pins and/or associated circuitry inside the N10. Magnector using my GNex AC adapter fails to charge while a USB cable in the N10 adapter works just fine.
I'm going to try cleaning the N10 pogo pins and Magnector contacts with rubbing alcohol and see if that helps. If not, I guess I'll have to buy a new Magnector. Hopefully, one of those two options pans out. I really prefer using the magnetized connectors on the N10.

Cleaning the pins on the connector using rubbing alcohol and a q-tip & lint cloth appears to have had some positive effect. The tablet charged overnight, while powered off, from 35% to 76%.
I have a feeling that a more thorough cleaning might restore the unit to full capacity. Anyone know of something better than alcohol to clean oxidized connectors?

So, my nexus has been good to me since I've owned it (2 years and counting), however recently (about two weeks ago) my nexus randomly died in the morning, while I was using it. At first I thought it was a simple crash as I was running Hells Doctor with TARDIS Mod, yet when I plugged my phone back in, I was greeted by a solid red light!
Fast forward a week I received a battery to serve as a replacement, as I thought it was the red light of death, yet after I finished installing the battery I hurried to go charge my phone back up, only to be greeted by the same solid red light.
Move up about three days, I asked my friend for his Qi Charger, as I then thought the charging port was damaged, left it overnight charging on the Qi Charger only to be greeted by once again the same solid red light in the morning.
Now I'm at present time of posting this, I'm starting to worry that my phone has had a hard brick, so I planned on going into download mode and doing a hard reset, but both my computers were not able to recognize my phone in download mode, nor did I ever get the download screen on the nexus itself.
I'm beginning to lose hope! I've tried all button combinations, tried 'jump starting' my battery, now I'm resorting to this.
Any other ideas? Or is it time to part ways with my beloved nexus?
What if it's a problem with your display connector ?

I've not thought of that, but if it is, then the price would be too steep for me
Ordered a second P2XL since they were $200 off. It was suppose to arrive Thursday but got delayed till today. Opened it up and attempted to turn it on, NOTHING. Put it on charge using my other OE charger, 10m later, NOTHING, 1hr later still NOTHING. I cant get it into bootloader. No LED or charging screen, basically no signs of life at ll. It does nothing when plugged into the PC either.
Anyone have any other ideas to revive this unit before I have to advance RMA another one? It won't ship out until Monday anyway, so I'd like to try my best.
I had a similar problem with a Nexus 7. I put my charger on a power strip that had an on/off rocker and toggled it a bunch of times until I jumped the battery back to life. It might be worth a try. I got the same deal this week and mine arrived at half charge. No issues for me. Sorry for your bad luck.

I did attach it to mu other P2XL and it does recognize that it's plugged into another device and I can choose supply power to device. I don't think it is though because battery is not dropping on the donor device. Sucks because I NEED the device now.
If your battery is totally flat it can be really hard to jump start it, which is why my Nexus wouldn't even take a charge after being totally run flat and shelved. Sending pulses of voltage in repeated bursts charged the battery enough to restore it's ability to charge. This may not be the case for you but it helped me. I found this method on xda.
