I have already submitted a similar thread, but this one I am going to keep shorter and simpler. I purchased an LG WCP-300 wireless charging pad from Verizon to use with my Nexus 4.
Sometimes the phone completes its charge, but it usually get to around 60-80% (depending on how low the battery is when I start charging) before randomly stopping charging. How do I fix this?
tl;dr wireless charging stops at random sometime in the middle of the night, but not all the time.
Optional details:
Pad is on a level surface and I have affixed some rubber grips to the top to hold the phone. The pad hasn't fully charged the phone for about a week now, but it does do some charging. I can get BBS logs if those will help anyone.
Maybe it stops because of overheating?

I also thought that could be the case, but my phone never gets hot while charging. :/
I had similar issue with my aTab 4, the problem was the USB charging cable. I never seen such thing before.
But i replaced it and it works just fine now.

Hi!
I've just received the Q9 Wireless Charger from a manufacturer in china.
It's Qi-compatible and have been seen working with the Nexus 4.
Mine does not seem to work.
The manual says a led should be shining green when it's ready to charge or when it's charging. It's hard to read the chinese translated manual.
Mine just shines red and blue constantly and nothing is happening with the phone.
Am i doing something wrong? Do i have to activate it in my phone? I've tried putting it in any direction in any place on the pad.
Someone have a clue?

I have the Energizer Qi charger and when I place the phone on the charging plate, a light over the plate shines a steady blue until charging is complete. Flashing multiple colors (especially if one of them is red) probably means there is a problem with the charging system or the power.

That's what i'm afraid of. The thing is that the leads shows blue and red all the time, even when the phone's of the pad. Updating with a picture.
try position it with the centre?
Done that too...

Is the power cord connected securely? Maybe it's not pushed in completely (or shouldn't be pushed in so far).
For what it's worth that's not the Qi symbol on the charge plate.
If possible, send it back for replacement. It seems to me that those two LEDs should light up for no more hen a few seconds after the device is plugged in and then turn off until they nerd to indicate some condition like charge complete or error.

I have the Q9 charger for couple of days.
It's takes many tries of locating Nexus 4 on chargers surface to make it work.
Many times (most of my tries) I unable to make it work at all.
I am wary disappointed with this charger. It was waist of many.
I shouldn't have to be such cheapskate.
Q9 Qi-charger broken
I had mine for about a week now. Used it with my Nexus 4. Charges the Nexus quickly, but when at 100% it stops charging. Only when unplugging charger and re-plugging it, it will charge again. One morning Nexus was at 77% while laying on charger. After a few times unplugging, the connector was pushed into the charger leaving it useless. Do not buy!
Just got one too
I have to place my Nexus towards the top of the charger for it to activate and start charging.
Took me a while to find the correct placement.
My pad is supposed to flash blue when its charging - It starts charging and then seems to stop, then start again, then stop - not sure if this is normal or not.
So far i'm pretty disappointed with it, I assume because I got a cheapy from china that this isn't the normal experience with QI chargers, but I doubt I will be buying another until I see someone else with a much better model.

IF IVE HELPED PLEASE HIT THANKS
This may be the noobiest of questions, but is there anything special that needs to be done to chage the unit or is anyone aware of units with bad charging ports. I just unboxed my Nexus last night and as my usual new device ritual put it on the charger for a few minutes. Noticed the battery icon came on for about 5-10 seconds and then disappeared. Figured it was normal but when I powered it on we only at 43%. Shut it off and let it "charge" overnight but when I powered it back up still at 43%. Tried a different cable with same results. Calling store today but wondering if I might have missed something.

A common problem seems to be that the battery connector is not properly seated during assembly. Pop off the back cover and visually inspect the connector. Also, there are a handful of threads regarding the issue you're having. You may want to search for them and check them out for some pertinent info.

Thanks. Does the back just pop off? Was running out the door to work so didn't get to search. Will check when I get home.

Ok, so got the back popped off and all look connected. Power the unit back on and somehow it's at 49% and my wife said when she picked it up earlier today it was at 55%. Checked the battery stats and it's been online for 9 hrs. If I plug it in while powered on the charging icon displays as if it's charging. Just tried leaving it powered on and connecting the charger and just leaving it. If I hit the power button the charging icon comes on, so maybe it is charging, just incredibly slowly?

My cable went bad within a month. Luckily, every other item we own seems to have the same micro-usb slot, so we had a ton of other cables to try, so that fixed it. But two bad cables - I wouldn't guess that.
Try to unplug the battery and replication it again. Open the back cover and do that. You need to be carefully and not to break the pins.

same here. I am using LG wireless charging pad
Sent from my Nexus 4 using xda premium
that's normal unless the phone overheats and shuts down charging. Wireless charging will heat up your phone faster than usb. i wouldnt worry unless your phone overheats and stops charging, this happens at 40-41 degrees Celsius.
BTW questions belong in the Q&A forum.
Has anyone with the verizon model used the wireless charging? I'm just curious how well it works. I have never had a phone that was able to do that so I have no gauge on how well the technology works.
Thanks
I got the official LG WCP-300 Qi wireless charger along with my Verizon G2 on release and it works well. The charging coils are located under the camera towards the lower half of the phone and you don't need you to find the 'sweet spot' for it to detect the charging pad. It obviously doesn't charge as quickly as plugging into the wall charger but it charges my phone from about 20% to full within 5 hours. I have the charging pad always plugged in on my nightstand next to my bed and it doesn't go anywhere. Hope this answers your question!
Edit: There's an LED on the front of the pad that glows a soft amber when not charging and turns to a bright blinking green during use. I just turn the LED away from my head at night and it doesn't bother me at all.
Yeah that helps. Does it work with a case on it? I'm thinking about just getting one that I can use at work. Leave it on my desk and just charge it as needed. It may may make things easier than having to worry about plugging it in off and on throughout the day. I probably don't need one really because the battery does last me all day, but I tend to get anxiety once the battery hits the 50% mark.
It works just fine with my LG QuickWindow case. I initially bought the charging pad for the same purpose that you want to do with it but after using it, I didn't think it would be worth it to leave at my desk at work simply due to the slower charging vs USB. If I left my phone on the pad every now and then it would only charge a few percent each time.
I'm using the anker one and it works very well with cases on. Doesn't get hot either
I'm using it with the stock gel case with no issues.

I got the Tylt Vu. It works great. It sits by my bedside. Every morning my phone is at 100%.
I have the Incipio Feather case, although I'm not using it currently, but I tried it on, and put it on the Tylt Vu, and it started charging with the case on.
I have a Nokia charger with the Diztronic case.. works fine.
I had the Samsung charger tray for the Galaxy S4, they mostly worked, but you had to scoot them up pretty high in the tray to get the thing aligned.. sent them back.
Nokia has 3 coils so it kinda self aligns.
So has anyone used the wireless charging with a thicker case? I'm going to be getting a G2, but the only thing that worries me is the lack of bezel. I'm paranoid that I'm going to drop it and want to get a thicker case.
I use it daily. Nokia fatboy. charge it over night every night through my incipio feather case. charged through the Verizon TPU as well.

I have been using my nexus 7 2012 for a year now .. it worked brilliant .. but now this horrible issues has sprung in from nowhere .. the battery wont charge up, or rarely it does,, but very slowly. i am running stock 4.4 unrooted . i have checked my ports for dust, swapped several cables and chargers (also used the original charger and cable). but with no luck. Surprisingly the problem appeared suddenly, one day it charged normally , the next day i left it on charge at 60% and returned to find it on 59%.. help me .. this is driving me crazy
Install the Battery Monitor Widget - should give you an idea of charging/power consumption. I'm assuming you've tried using the stock charger and cable?

I think your battery connector is messed up. U might have to open your tablet and disconnect then reconnect the cables.

]I too have this same issue....
I have the official dock and never had any charge issues until yesterday....
While it's in the dock, it clearly shows it charging and yet the battery meter appears to be losing charge...
I have tried with the original cable and plug among other cables and yet nothing...
The only way for me to get charged is to turn the unit off and yet it still charges painfully slow...
Anyone with a solution other than opening the thing up and hoping it's the plug?
I am running 4.4.2
Mine's having the same problem. It seems to be a hardware problem.. It's charging very slowly or can't be fully charged.
* I have other devices running 4.4 without charging problems.
Mine started with the 4.4.2 update....
It's very strange... If I turn it off and charge... it charges (again) very slowly.... 3 hours and I went from a 2% charge to 59%...
Doesn't matter if I use the dock or plug it in direct.....
So, to me... I would say a software problem... I just don't want to do a full reset and re-install if I don't have too...
my wife's was all the way dead today after not being used and wouldn't turn on. left it plugged in for 30 min and it powered on with only 2% battery. i t is stock unrooted and everything was all good until 4.4.2 is now charging very slowly. I switched to a non oem usb wire with the asus charger to see if it helps. it is the only stock android in my home (out of 7 devices) and I plan to keep it that way for now.

N7 is very easy to open and close back.
I had the EXACT same issue 2-3 times this year and disconnecting the cable and reconnecting it back fixes it EVERY TIME.
The battery cable is short and the battery is loose so movement pulls the cable out. Not all pins are touching so it results in poor contacts or no contact at all.
Its a design flaw that can also be fixed by sticking a folded paper under the battery.
Voilà!

They originally looked pretty secure though... pretty tight....
Here's hoping that unplugging and plugging the battery back is solves the issue...

Tried unplugging and replugging but it's still the same. I think it's my charging connector though. It randomly disconnects when I plug it into the PC. Tried with 3 different cables even the stock one. But I'm not sure if it's the port or the battery. It charges up to < 60 slowly but it doesn't go beyond that and starts draining. Thinking of selling it and getting a flo instead

Just a thought, but another possibility is that the ribbon cable to the USB/headphone jack flex assembly has worked loose to the point of intermittent connections. See "step 10" of iFixit's N7 teardown
Or, if the connector itself is mechanically damaged, maybe there is some way to buy just that Asus sub-assembly. Anyone have a source?

Edit - wow, folks are selling them on eBay for US $50. yikes.
I have the same problem, I purchased a nexus 7 charging dock from Amazon and it charges flawlessly. The dock charges using the 4 pins on the side of the tablet. BTW...The charging dock is under 24.00+ Shipping.
