Hi! Here on XDA I found few similar situations, with various phone models, but no right answer...
I have a brand new battery (but same situation was with the old one) and when I connect my Note to the PC USB connector or when I plug it in my car charger, phone is still discharging if the screen is on. If the screen is off and if I close all apps, wi-fi and GPS it is charging but very, very, very slowly. Only if I plug phone into wall charger it doesn't matter if the screen is on or off, is it wi-fi or GPS turned on or off, phone is charging normally. I try few different cables, but still the same. Computer have only USB 2.0 and 3.0 ports so it isn't a USB 1.1 case. I have also HTC HD2 and it is charging normally no matter where it is plugged - wall, PC, car (same chargers, same cables, same PC...) HD2 is charging in my car even if the GPS and navigation is turned on.
Any thoughts?
Thank you!
Laptops tend to only put out 500ma which isn't typically enough for the Note. It cod be a mixture of low amperage chargers and slow charging cables. The Note (imo) is pretty inefficient on stock roms.

Thank you! I'm not charging it over laptop, but over desktop PC and in my car. I try to charge it with Samsung original cables, with HTC original cables and with cheap china made cables, all 3 cases - same. Also I'm not using stock ROM but SOKP KITKAT ROM

When I first got the phone earlier this week, I could plug it into the charger in the wall just fine with no issues, it would just charge. Now suddenly it started telling me USB connected and goes to the MTP screen and of course locks up the phone.
I can of course bypass this by switching the phone to mass storage mode, but since I have Kies and use it occasionally, it would be nice to not have to switch that setting each time depending on my charging/syncing situation.
Why would it have not locked it up with the MTP screen originally when charging from the wall but now it does? The results are the same whether its plugged into the wall or the USB port on the computer. I have two Captivates bought brand new on a family plan, both do this now with any combination of chargers and USB cables, wall USB port, or car charger. Neither one has a common application installed since the other is my girlfriends who hasnt done much to it yet, so Im blaming the phone itself for now...

Interesting. I just checked with my BB charger and they dont do it using that charger, but they do it as soon as I connect the stock charger again.
Im wondering if its a voltage sensing circuit thats tripping due to the different voltages which should be applied - either wall charger or USB port. Maybe for some reason my wall chargers arent putting out enough voltage and its thinking its a USB port, but the BB charger is putting the right amount of voltage out?
Am I on base as to how it differentiates between wall or USB port? The number of pins obviously doesnt matter as all the cables have all the pins in them, unlike some charger cables which only have the power and ground. The only thing I can think of is that it uses the amount of voltage/current to tell the difference and create its reaction.

Sounds like a problem with the stock charger, maybe usb cable alignment. My iphone wall adapter does this with the samsung cable but the samsung wall adapter doesn't, same with my car charger from att. Also I have a $5 walmart car charger that has a cable that splits into both a mini usb and a micro usb that isn't a real usb cable, it's charge only. That cable has no problem on any wall or car adapter. I believe the phone detects if its connected by checking voltage on a data pin (just a guess really) so if a nonstock charger is used it assumes that it is a computer. But it may also be a data signal that is given off by the charger.

did you try a new charger and if so, did it work? I've had my captivate since Thursday and on Thursday it charged and everything fine, but then yesterday,
a) no computer I connect it to while recognize it, no matter what I have it set too and have latest drivers installed
b) if I charge it, after I unplug it, it locks up to black screen and I have to remove the battery to get it to work
c) I also have an in-dash touchscreen monitor in my car that has a usb port because it works with an ipod. I plugged the usb into to use it as a car charger, unplugged it, same thing
d) it did say usb connected after it was unplugged, but I switched from mass storage to ask on connection and it went away
so is an actual wall charger the solution?

and now I unplug it, and if it locks, it will not unlock, just black screen
I have to take out the battery and then only way to get it to turn back on, is to plug it back in the wall

^^^Ouch that's not right, if you can't figure it out you may need to re-flash or just bring it back under warranty, or insurance

So this is my first motorola and I had heard of the issues they have with non motorola chargers. Now I am experiencing it first hand. With the same ac charger I have charged many phones with and is capable of 1 amp output (D4 charger is only rated at 850 mA) my D4 struggles. With the device off it charged painfully slowly. While on it cannot even charge. It discharges while plugged in despite the charging indicator and reporting "charging (AC)" in status.
How does it know it is not a moto charger? Is it just about the resistance between the data pins? For most other phones shorting the data pins on the charger indicates to the phone that it is a high current charger and not a computer USB port. Is there a similar trick for motorola phones? I would rather not have to purchase an overpriced moto oem car charger. I have a perfectly fine 1.2 amp car charger soldered directly into my car's 12v system behind the dash. Can I make it work?
Thanks!
On a regular basis I successfully charge my D4 using both a charger from a Samsung Reality feature phone and from a B&N Nook Simple Touch, in addition to the one that came with it. I've also used a variety of car chargers.

Actually, so far I have only one charger that had any trouble charging the phone (it was a $3 charger with 2 USB ports), but the $3 charger with ONE USB port works fine, as does the Nook Color charger, Blackberry charger, and Samsung charger I have tried it with, as well as both my old car charger and Lenovo's always-on charging port on their laptops.

Not sure how it knows one way or the other. I've successfully used a few LG chargers to charge my D4. The only really hickup I've ran into is the usb cables from those lg chargers won't sync data to the phones when plugged into a computer, they'll still charge off the usb port but won't read as a usb connection to the computer.
Heh, captcha is trynply.
Every charger I've used, including an old charger for an EN-V, kindle, supplied, and various other phone chargers works just fine with this phone. Probably have a bad charger, guy.
Thanks for the replies. I guess I was wrong. My modded car charger works just fine. I guess its just time to retire the old charger that I have been using. I think it might be my old nexus one charger.
A more important question would be does the thing charge over computer-bound USB ports?
When you're without a charger, but there's a USB cable that fits your phone, sometimes a regular USB data port is the only that is around... even though it might take a really long time.
Try a computer bound USB port, then try your actual charger, again. Or do the hard reset (vol down plus power, hold until it actually does it), which is just like pulling the battery.
See how that goes.

It does in fact charge via USB port. In fact, it has a 'charge only' mode. Depending on how much juice your port puts out, and what you are doing with the phone, it will charge slowly/not at all, though.
from my experiences, the droid 4 will not accept lg microusb cables, the charging bricks work tho. i use a blackberry microusb on mine along with a Logitech and the stock moto ones. 1.2 amps is a bit high but not crazy sounding. personally, I charge at 1 amp.
after years of not issue, yesterday my note stop charging in the outlet chargers, I have several all do not charge it but have no issues charge my wifes phone.
but I can charge the phone with the same orig cable when the usb is my computer and not the outlet.
any clues why my phone will charge in my computer with same cable but not in orig outlet plug. please tell me I do have to have my $2K high end gaming desktop on just to charge my phone in its usb slot.
I cleaned everything, it is a new battery

any help is apprecaited
I guess problem is in your adapter..try different adapter and see if it helps

I have tried 4 different adapter/cords combos ( just in my house) none of them charge my phone in an outlet - all work with my wife's smaller samsung in output. so weirdly only a direct usb with the oem cord to computer works ( in both my desk and laptop). so weird. so annoying.
You have to buy a new charging port, and the board that comes with it. This is a link to the part you need. If you search "n7000 charging port flex ribbon" you should be able to find other places that have it. http://www.etradesupply.com/oem-samsung-galaxy-note-gt-n7000-charging-port-flex-cable-ribbon.html
By "directly" I mean using regular USB data cable (most likely USB->Micro USB) and NOT special charge only cable that has data pin shortened to draw higher current.
The reason for this post is that I found that my new phone (Moto X) doesn't charge when connected directly via regular data USB cable even though charging indicator is on. When idle it still loses several %/ hour, when running Google maps - much more.
After Googling I found that if the phone is connected as USB media device it draws less power from USB and it may not be sufficient to charge phones with high capacity batteries. Workarounds include using charge-only USB cables that have data pins shorted, cigarette lighter chargers or AC charger if your car is equipped with AC socket (mine is, but what a pain to have to use it for this!).
Here is my situation on '11 Jeep Grand Cherokee with 430N (2 USB ports, Android phones are recognized as media device on both):
Old phone (Droid Incredible, 1300 mAh battery) charged fine when idle via regular data cable even though it was in media player mode. I haven't really used it when running Google Maps much so can't comment on that.
New phone (Moto X, 2200 mAh battery) doesn't charge via regular data cable (even though indicator shows phone charging). When idle it still loses several %/ hour, when running Google maps - much more. I tried 500 mA cigarette lighter charger and it charges it fine in idle, haven't tried while running Google Maps yet.
The USB power in my truck is provided by one of these:
http://daqstuff.com/400116_5volt_switching_power_supply.htm
The only mod I made was to short pins 2 and 3 on the USB ports, which is required for full current charging with a Nexus 7. Dunno if the Moto X is the same, but it charges just fine when plugged into it.
My Moto X does not charge from the USB port in my Acura. I use a USB adapter in the cigarette lighter if I need to charge it.

Wow 2 amps. At home my iPhone is good for something! Its 2 amp wort charges the x fast!
Yes all phones charge in my Hyundai but very slowly since its only a regular USB port not a charging port. I use a Griffin dual USB charger instead.

Moto X does not charge in my Honda or Volkswagen via car's USB port. All my previous phones including nexus 5 did. For Moto X I have to use car charger.
From my Moto X, in your face!
My wife's X does not charge via her aftermarket stereo in her Subaru. I have not tried it in my F-150 though.
Standard USB ports in a PC supply 5V and 550mA which is not enough to charge current smart phones. If you are using apps, 550mA is not enough to maintain the charge level (i..e if you have 90% charge, plug into a standard USB port, and use Google Maps or stream a movie from the internet, your battery's charge will slowly drain. Not as fast as when unplugged, but it will drain).
The X ships with a 1150A adapter. I've used 850mA to slowly charge the phone.
I've not metered the voltage and current coming out of my car's USB port.
I use a dual port USB charger that outputs 2.1A per port. (its either Griffin or Kensington)
I stumbled across this issue when I tried to charge my X in the car. I have an old nokia car charger (had nice thick writes and curly cord) that I cut the plug off and soldered a micro usb plug and a resistor between pin 5 and ground for activating car mode on my SGS2 (i9100). I plugged in the X, nothing. I did some research and found that shorting D+ and D- puts it into AC fast charge mode. Charges fine with the screen on. Luckily the old nokia charger has enough grunt to cope.

Yep
Interesting. Mine does charge via the USB cable on my aftermarket head unit, but it is fairly slow. All I care is that it doesn't drain the battery at all for 4 hours car trips while streaming music and running Google Maps with the screen on the entire time.
mine slowly/medium charges with MyLog and CarHome Ultra or Nav.
I have a magnet and SkipDot in my car dock to auto unlock and trigger car mode which launches CarHome Ultra. I use Llama to further trigger and enable bluetooth and gps as well as disable WiFi. bluetooth connecting to my JVC head unit triggers My Log and automatically logs journeys for tax. Llama cleans up and turns of gps/bt which causes MyLog to finish too.

Just got my new 4a5G mostly set up last night and plugged it into my multi-port charger for the night, and found that it won't charge at all. Tried another high-power charging brick from an old samsung tablet of mine and the same issue. My 3XL used to have issues sometimes charging too slowly on these bricks, but at least it charged. I was expecting the newer phone to fix this issue, not make it worse by not charging at all. The included charging brick works, as does the charger from my Samsung chromebook.
Why not use the included charger? Well I have 3 devices that I like to charge next to my bed at night (phone, chromebook, smartwatch) and only two free outlets. Chromebook, needs its own dedicated charger to fully charge overnight, so I typically have the phone and smartwatch plugged into a 4-port charging brick. This thing supports QuickCharge 2.0 on one port and the other ports cap out at 2.0 A, so it should easily be able to deliver a full charge overnight, but the 4a5G refuses to recognize it at all. Doesn't matter if I plug it into the QC port or one of the other ports. What the hell is up with Pixel phones being so picky about what you charge them with?
Update:
So it wasn't the charging bricks, it was the cable. Tried two of the same brand of cable, and they didn't work at all. Tried another USB A to C cable I was using for a different device, and it works! These cables work just fine for every other USB-C device I own. No flaky connections where you have to wiggle the plug in the port to get it to connect. They connect and stay firmly connected consistently on every other device, but the 4a5G just refuses to recognize them at all. So its picky about cables, not charging bricks. That's not nearly as bad, but still annoying.
Indeed! Also to note that I also learned that this phone needs a charger that has Power Delivery technology. I tried using the adapter from my previous phone that had quick charge 3.0 technology but it was not charging rapidly.
