I have my ls990 on BarePop, which is the only option that I know of that has a working NFC. I'm all set up for wireless charging with the wireless sticker on the inside of my cover and if course the wireless charger.
When I set it on the circle, it starts to charge, gives me the warning that charging is slower than plugging in, shows charging for another 3 or 4 seconds, and then stops charging. This has been an issue since I hooked myself up. The charging drops after about 15 seconds.
I wonder if it's a shoddy sticker (which looks to be correctly placed) or a funky charger (Ankor from Amazon). Has anyone experienced this symptom or know what the problem could be?

Did you use a power adapter that is rated 1.5A or above? I used my old Nexus 5 charger (rated 1.3A) and my Qi charging is cutting on and off. Once I changed back to the original G3 charger, the Qi charging is stable.
That might be a really good call! I thought it was a good charger by a trusted manufacturer, but I checked and it's only a 1 amp output Anker. Makes sense, especially if you had similar symptoms with a low amp device.
Thanks for responding!

Is there an app or widget that will display the charging current that is charging the battery? I have a car charger that is supposedly 1A but it seems to charge much more slowly than my 1A home charger and would like to compare them more directly.
Thanks.
Had the same issue here .. looking in to my account and check my posts the answer is there ... shipped from us to UK in a week in my case and I can see huge difference ....

If you want you can see which charging method your phone is using. Settings>battery. If it says charging(usb) the most you are drawing is .5 amps. If it says chargin(AC) then you can pull up to an amp. If you are getting usb charging from a car charger, you don't have the data pins shorted. if you short the data pins, it tells the phone that your charger is a 1a wall charger.
It did say USB. I cut open the cable I was using and shorted the white and green together. Now it says AC. Let's see if it can keep up with BT streaming and navigating.
Thanks.
Unfortunately there's no way to see charging current on this phone like many HTC phones have. But you want it to say ac not USB else its only pulling half the current its capable of.
Worked like a charm. I turned the brightness up, streamed music over BT, and left navigation on during my commute this morning. The battery actually charged instead of drained. Good stuff.
Glad I could help
Great info. Been wondering about this myself. Thanks!
When I plug in my power adapter to charge the tablet more often now I get the Slow Charging notification that says battery is charging slowly due to low electric current of TA/USB connection. Any one else seeing this? I am using the stock charger supplied with the tablet. I have tried this on several AC outlets in several different locations. It does not seen to affect the ability to charge the tablet it just charges it a little slower.

Thanks for the reply. I am starting to think my power adapter is not putting out the correct current it should be. I will try using a different 2A charger and see how it goes.

You might also try a different cord!
You may try to install "battery monitor widget", it will tell you charging in USB mode or AC mode.
I also find the stock LG charger slow charging, the widget shows I'm only charging at around 1100mA max. While the charger itself label said Output 1.8A max. I can't reach this level yet.
If I charge with a stock nexus 7 charger (which is 2A rated), it'll get worse...just reach around 800mA max.
I'm still not sure what's wrong with the charger or the tablet itself...
I can say that the cable that came with the gpad does charge faster than a thinner cable I had. Both were tested plugged into the stock LG charger.
Sent from my LG-V500 using XDA Premium HD app
When I pulled my g pad out of the box and saw the stock charger was below 2A I put it back in the box. I charge my tablet with the 2A charger that my note 2 uses.
I've seen this problem intermittently with the stock LG charger and today it seems to have become a permanent fault. Swapping to my Note 3 charger things are back to normal once more. Swapping back and forth repeatedly the LG charger triggers the warning and the Note charger is fine. It looks like the LG charger is a bit rubbish. I'll press for a warranty replacement.
I have noticed mine recharges really slowly as well. Using the stock charger, and the battery app previously mentioned, it gives me about 1.1A from the stock charger. Using my Vita charger rated at 1.5A I get about 1.4 into the G Pad. It seems their charger just stinks.
I sent them a support query to see if they will replace it without hassle, if they want me to send it back I'll just buy something else instead.
Edit: Heard back from LG, they want me to send the whole thing back to them or return it to Newegg. Not sure why they won't just ship me a replacement charger, it would be much cheaper for them in the long run.

Further investigation revealed the original cable to be at fault, as it would not make a data connection with either of my laptops. Another cable from my old Galaxy Note worked perfectly. Even so there is still a question mark about the charger as well. Today I spoke to an LG support rep who promised to send a new charger and cable. They should arrive within five working days. I had read of mixed opinions on LG's support, but so far it all seems encouraging.

I bought this item and IT WONT WORK properly with Nexus 5 Phones.
To sumarize:
- It's behaviour is erratic. Sometimes it charges the phone, sometimes it doesn't. Sometimes it charges for a few minutes then it stops with no apparent reason. Sometimes the green light (means the device is charging) is still lit but the device is not charging anymore...
- if you try to charge the phone overnight you can wake up with a bad surprise (as I did) and the phone powered off because it stoped charging.
- During night, I use gentle alarm and it keeps my screen on (dark, just showing the time). It seems this QI charger is not even able to deal with it because it stops charguing the phone after a few minutes. If you pick the phone ant put it in the QI charger surface it will start charging again but, once again, it will stop somewhere later. USELESS!
- It is not able to hold the phone. Not at all. I thougt my phone would stick to the charger but it wont (maybe this charger can hold lighter phones, but not the N5). The only way I could make it tho hold my phone was keeping the protection plastic film that came with the charger (and is suposed to be removed and thrown away) as it seems to increase the adherence between the charger and the phone.
In short: I'm disappointed and have to advice you all not to buy it.

What are you using to power your Qi charger? From the sounds of it turning on and off and having sporadic performance, it seems like it is not being given enough juice. Are you just plugging the Qi charger/included cable into a PC USB port or something?
The best way to make sure a Qi charger works properly is to plug it into a wall outlet using an AC adapter/cable that provides equal, or more current than the required input. Your Qi charger says Input DC 5V 1.5A. So you should have an AC adapter that provides that, as well as a USB cable that supports high speed charging (like the stock Nexus 5 cable).
Have you tried using the stock Nexus 5 AC adapter and stock Nexus 5 USB cable? Most included USB cables that ship with Qi chargers are quite crap. I know that the stock Nexus 5 AC adapter is 1.2A, but it is still a good block and should power your Qi charger well enough until you get a higher output AC adapter. If you haven't, try testing your Qi charger using that block and cable and see if there is an improvement.
Yes, I tried all that. I used several ac adapters, including N5 charger and 2 Samsung adapters

I guess if that's the case then try contacting the seller and asking for a refund or replacement. You probably got a lemon.
Tell them it doesn't perform properly or show them with pictures and/or video of the slow charging/disconnects.

Just put CM11 M8 on my kindle fire hd 8.9, love it, but have one question. I notice while it's charging, the lock screen will switch between saying charging/discharging. Meaning when the screen is off, as soon as I turn it on it says charging, then 1 second later it changes to discharging and stays that way...this is all done while the screen is locked. It looks like it is charging albeit extremely slow based on the percentage increasing...but is this normal behavior?
I've already tried two different usb cables.
What are you plugging the KFHD into? I have charged mine from 1A, 1.8A, and 2.1A ports, and while I don't remember ever seeing it switch back and forth between charging/discharging. As a side note, charging from a 1.8A or 2.1A port leads to fairly swift charging (I've used the original KFHD USB cable as well as AmazonBasics 1m and 2m cables with no change in charge time).
As a side note, I am also on CM11 M8
I'm running nightly builds with the Amazon 2.1 amp charger and have not seen this problem. Perhaps try a different charger to see if it still happens, it may be the charger itself.

Yes, I'm having the same issue. In my case, the unit reports 'not charging' even when it clearly is. I have no idea what the problem is, but as long as it charges, it's something to ignore.
It's no issue of CM - this is normal when you use low-power charger (effect is the same when charging from PC or Notebook USB ~ 500mA).
When you turn the screen on, power consumption is increasing and charger has not enough power to deal with it.
I recommend you to buy more powerful charger.
>1,8A chargers should charge easily even when the screen is on.
as an update; it seems that as of recently (I've switched from CM11 M8 to Liquid Smooth v3.2) the charging has slowed significantly. I don't use it all that often, so as of lately I've gone >1wk between charges. Two nights ago I plugged it into a 2A charger (intended for a Galaxy Tab) at 24% at 10pm, at 5am it had only increased to 77%. Last night, while plugged into my Galaxy S5's 2A charger it took almost all night to charge about 50%, and this morning it stated "99% Discharging" while still plugged in.
This is an interesting thing...
My Pixel C tablet does not start to charge immediately when I plug it in to any charger. It registers that it is plugged in straight away, the battery icon changes straight away to the icon with a lightning bolt and the Ampere app registers as being plugged in, but it does not start charging. The battery information screen says 'Not charging' and ampere says the battery is still discharging. After about a minute this usually changes and the tablet does start charging, but a couple of times it has not charged at all while registering that it has been plugged in for half an hour.
This happened with my brand new tablet, so I returned it and the second and third replacements have been exactly the same. This happens using different chargers and in different locations (I have tried different sockets around my house and at work).
Has anyone else experienced this? I am about to return my third tablet for a refund as I don't want such an expensive device that I can't trust is going to charge.

Mine does this. I just chalked it up to new USB C charging standard and it calculating what to pump in to the battery before it begins.

Has yours ever not started charging eventually? That's what made me call Google support and the four people I have spoken to there all say it not charging immediately sounds like a fault.

It has always begun charging. Hell, maybe mines faulty too, but I never thought of that.

Mine does this, I wondered if it was a USB C thing too. when I plug it in the charging icon appears immediately but Ampere shows plugged in/discharging, the discharge rate starts low at approx 300mAh and over about 30 seconds rises (drops?) to, for example 1750mAh before flipping to displaying charge at 1750mAh. The final plugged in/discharge rate always matches the initial charge rate measured.
I usually charge using an Anker multi port charger and USB A to C cable. it behaves the same but with higher numbers with the Google supplied charger.
I am curious to know if USB C negotiating its best charge rate somehow fools Ampere?
I just bought a Pixel C and I am using it with a generic 5V /2A charger and a Dash usb C cable. It does the exact same thing that the OP described. I have to plug the USB end of the cable into the charger once or twice, before it starts charging. If I just plug the tablet in normally the lightning symbol appears and it does not start charging.
USC Type c takes 10 secs to negotiate. I would not use other chargers or cables. Stick with stock or known tested working ones. Refer to this spreadsheet
https://docs.google.com/spreadsheets/d/1vnpEXfo2HCGADdd9G2x9dMDWqENiY2kgBJUu29f_TX8/pubhtml
Remember ampere is not accurate and is only a best guesstimate. I recommend using current monitor in conjunction.
Becareful using generic cables and chargers risking frying your devices. If the cable is not made programmed correctly missing emarker or same for charger, USB Ttype C Power Delivery cannot not negotiate correctly. If it's missing altogether it may overcharge..
I've found the Pixel C to be a little picky with its chargers but the only really big disappointment was with the Pixel phone charger. That charger is supposed to support Power Delivery and can charge faster than the Pixel C charger can so I naturally plugged it into the tablet and it is useless! It connects and disconnects continuously so it never accomplishes any charging and the screen will not stay off. You'd think a charger and a device designed by the same company, advertising the same USB charging standard, sharing a marketing name, would work together!

You might have a defective Pixel charger or cable, it has been known to happen. That is why people have gotten replacements.
On that note consider that the Pixel comes with the same charger as the XL, but it doesn't charge at any faster rate than 15W with it's own charger..

Yes, I have heard that the Pixel-xs doesn't make use of the higher voltage (9v, I think?) charging option, but I was hoping the Pixel C would. It is known to work with other higher power chargers. Maybe I'll call up the old Google and see if my charger is bunk. Even if it is no faster it shouldn't cyclically fail to auto negotiate like it does.

The Pixel C is 5V/3A 9V/2.67 12V/2A. I use both the Xentris/verizon USB-C/QC ($9-40) and Targus 45W ($30-55) chargers, both charge my Pixel C at 24W 12V/2A. It's great.
I have just purchased the Belkin charger cable that is on the Google list. The tablet's behavior is still hit and miss on the 10V/2A chargers that I have. I am using the Samsung S2 charger (should be plenty good quality). I am not even looking for fast charging or anything, just consistent behavior. If I plug in the usb C end of the cable ampere starts to show a discharge rate of like -500 mA and it does not start charging. The built in battery indicator says USB Charger = not charging. This happens about 7 times out of ten. In the other 3 cases it starts charging when the USB C end is plugged into the tablet. If I look at Ampere and see that is does not charge for like a minute, then I unplug the USB 2.0 end of the cable from the charger, re-insert it and voila it starts drawing 2000 mA immediately. I have tried 3 different chargers so far and the behavior has always been the same.

The Pixel C uses USB Type C Power Delivery 5V/3A 9V/2.67A 12/2A. 24W max
Ampere app is rather useless and just for reference. (note I use it often) Try Current Monitor. Regardless both rather useless, since the Pixel C doesn't negotiate faster charger until after the screen turns off. So while you have the screen on looking at Ampere/Current Monitor, you're gonna get a fluctuating reading that doesn't make sense. I use a kill-a-watt to see the wattage being pulled.
I am able to get a solid consistent 15W charge out of the stock OEM charger. I can get anywhere from 15W (screen on) with my Xentris/verizon and Targus 45W chargers and 24W (screen off).
Also note USB-c is not consistent, it negotiates different levels and it always changing depending on several conditions, like battery level, temperature and if screen is on at the time.
I've attached some results using LG V10 OEM Charger, Samsung Fast Adaptive Charger and Asus Nexus 7 charger with USB A to C with 56k ohm pullup resistor connected to the Kill-A-Watt for reference.
