    I noticed a red x on battery on main screen while using same power strip as normal. Plugged into house outlet directly and x went away.

    I get the same red X trying to charge from a computer or the wall plug. If the tablet is not fully powered down it charges extremely slow even plugged into the wall. Even fully powered down from 20% plugged into the wall after 12 hours charging it's only at 80%. When plugged in and being used it looses power slowly. Battery life from a full charge seemed good I watched 4 movies in a row off a full charge but recharging seems impossible it's brand new.

    I bought my Samsung Galaxy Note 10.1 yesterday morning (Friday 8-31-13), I got it home and plugged it in with the supplied charger turned it on, did the setup and played with it half the day. It was charging fine, as soon as it hit 100% I handed it over to my wife and she watched netflix and hulu all evening. This morning she played a game on it for a few hours and all was fine. I finally got it back from her and I indicated that it needed up dates, I let it take all the updates and now after the updates it charges VERY slowly while its turned on and it also charges slow while turned off. I'm sure its due to the updates, I really like the tablet but I may return it, this issue makes me nervous.

    Glad I found this forum.

    I also get the red x over the battery symbol when using pc usb, any external charger as long as the note is on. I purchased a mycharge 6800mah charger just for the purpose of charging my note on the go, instead of running around like a chicken with its head cut off looking for outlet to plug my note into! I would love to know if there are any external charger that you can use with the note while still on. So far, I haven't found any data or forum with anything to the contrary.

    If you use the charger that came with your Note 10.1, does it still charge slowly? I think folks are a bit confused thanks to some poorly informed Samsung person. The chargers for the 10.1 are 2.0 A., or in milliamps - 2100 mA. Most usb ports whether in a power strip or else where are much lower current and will be a trickle charge which causes the red x over the battery icon. Even if I accidentally put the usb cord into my original Note's AC adapter's usb port, I get the red x because it's only 1 A. If you need extra adapters, Radio shack has some that are 2.0 or 2.1 A. Just be careful of some adapters that have two ports and say total is 2.1, each usb port is only 1.0 or so power. Or sometimes they'll say 3.0 and it means one port is 2.0 and the other is 1.0. Ports off your computer that are 2.0 usb are only 500mA, that's a quarter of what the OEM charger is. That's why it slow to charge.

    The charger you use MUST be 5V / 2amps to get the lightning bolt. Anything less than 2amps and you will get the red X. I had experimented with about ten different chargers with amperage outputs from 0.5, 0.7, 1.0, 1.2, 1.5 and 2.0. The only one that worked was the one with 2.0amps. Use the wall plug you got with the Note.

    Well I got my note 10.1 on Christmas and since they I have always charged it via the supplied cable and wall plug. I recently bought a 10000mah battery pack to use to charge cellphones, ipods, my note 10.1, and other devices when I'm away from a wall plug. What I found out today.

    The battery pack will not charge a galaxy note 10.1 while the tablet is on. A red x appears over the battery icon on the note when you plug it in while device is on. I turned the note off and the battery charge icon started moving so i left it plugged into the battery pack for awhile to see if it charged it all. After about 30 minutes hooked up to the battery pack while powered off the note 10.1 did indicate that it had recieved a charge (it was at 57% when i plugged it in, and 63% when i checked it later on). Another funny thing is I have a belkin surge protector that has usb plugs on it so I tested it on that. Again with note on you get a red x over the battery icon. Humbled by this I plugged my note 10.1 into the plug that came with my s3 and I get the same red x while note is on. So what is it with the actual plug piece that goes into the wall outlet for the note 10.1 that it is the only way to charge while the note is on? Same thing happens when I plug my note into my laptop get the red X over the battery icon while the note is on, but if i turn it off it charges. Has anyone else noticed this as well and has the same findings as me or is something wrong here? The only way i get a charge status on the battery icon in the notification tray while my note is powered on is if it is plugged in to the wall plug that came with it, any other charging methods I have tried require the note to be powered off.

    I WAS having the same issue, even using 2.0 Amp chargers that weren't Samsung brand. I found a very simple and cheap solution. Rather than trashing your good chargers or spending all that money on a Samsung compatible, use one of the following with a standard USB micro cable. I guess it tricks the tablet in to thinking it is plugged in to a Samsung charger, so it then doesn't slow itself down from charging.

    My Samsung Galaxy Tab (bought in Oct 2013) always allowed me to read books or play games in an app while plugged into the USB on my laptop and it would continue to charge up. In the last couple of weeks I noticed that it is no longer charging while in use when plugged into the USB. I have continued to use it for a while to see if it just kept the battery at the same level or increased a little and no, it just keeps discharging. The only thing I've done differently with the tablet in those weeks was add some other apps. It will charge overnight on the USB if I turn off the tablet completely. It charges just fine when using the wall plug too.

    I know this is old, but:

    I work in China, so this was all of 1.50! :-)

    A similar device at Amazon.

    Now any USB charger will work.

    I wouldn't use this on a computers USB port as it probably draws too much power. think it draws 2.1 amps. Perhaps somebody more technical can chime in here.

    IF you charging device does not put out 2100ma (2.1 amp) at a solid 5 volts you will get red "X".... Period.... Most phone chargers and USB ports on PC or laptops are limited to what their miliamp out put is.... Recently bought a Rocketfish 2.4 amp output (2,400ma) for mobile use and all my red "X" problems went away (for auto use) .... Its very important there is enough voltage (solid 5 -5.3 volt ) and enough amperage (2.1 amp) that "note" will be satisfied when charging... Most USB ports are limited to a 200ma output (PC or laptop) so they will never sufficiently keep up the charge, they barely will maintain device in running mode and may no even produce enough power to charge unit when it is on...Some people have also complained when using USB extension cord on charging they get red "X" ... Well its the quality of the cord and wire gauge inside of cord that is problem....If its not a "heavy duty" USB cord there is sufficient voltage drop (below 5 volts) to make unit unhappy with power its getting for a good charge.... So dump the $10 chargers and throw away all the flimsy USB cables.... Good quality (expensive ) charger that meets tablets specifications is only solution.....

    To small of charging device and cables are like trying to draw a really thick milkshake through a very tiny soda straw..... Getting a bigger straw is probably the solution...

    I have the same thing. I left my charger somewhere on holiday so had to buy another one and its slightly different. Ever since I have this new charger I get the red arrow and it says "discharging" in the battery info in settings. It also take forever to charge and I have to have my note switched off. Apparently you cannot buy the original chargers so have to make do with generic ones and these don't work as well. Very unsatisfactory.

    There are aftermarket chargers for the note 10.1 available, and Samsung can supply an original, if expensive, one. I'm not sure where you are, but:

    I bought a "rapid charger" by belkin at Walmart that specifically says compatible with galaxy note 10.1. It does charge it when the tablet is off but I get the red x if it is on.

    I thought I couldn't charge my Note 10.1 in the car. I didn't try to turn it off and charge it. I just turned it off until I could get to a wall socket. I love my Note 10.1, but I want to use it when I travel and I get the red X when I try to charge it with the USB, that was meant for Tablets. I am glad I am not the only one.

    I'm a computer scientist. Because of all the interest in the charging problem on tab 2, I selected it for examination. I bought 10 tab2 machines with the charging problem and destructively analyzed each one and compared results. here is what I found. in all cases the wall unit was good. in 9 cases the tablet port was good. the one bad case was a "fine stainless wire" was found in the tablet port. I disassembled the tablet to the port and the charging cable port.. No damage to the tablet port. On the cable, on the tablet end I dissolved the shell with solvent and found where the "fine stainless wire" belonged. The wires from the cable come into the shell and are connected to the pins with "fine stainless wires" straight in the middle and bent slightly toward the outside on both sides until the last one is approximately 45 degrees. that's the one that had broken. I believe it broke partially at the connector end first causing intermittent charging with or without an error message (icon). It would be possible at the current available that the pin could reweld upon insertion making a temporary good connection. (until the next insertion).when it finally broke at the other end the machines battery could not receive a charge because the broken wire causes "power good" signal not to appear to the tablet. I reconnected that pin and it worked fine. I also believe that the wire broke because of insertion errors. Samsung says CAREFULLY insert it squarely into the port. If you tilt or press it in hard at an angle to the left, you will stress the wire inside. Be advised the repair requires equipment the average person wont have and it will look pretty bad even if done by professionals. another cable will have a 90% chance of fixing the problem. buy Samsung. Please forward this to anyone you feel will benefit . I wish good on you, have a fun life.

    I did not have this problem with the Note 10.1 that was purchased in September of 2012 until I replaced the battery very recently. I specifically ordered the Samsung battery and expected it to behave as it always had, but now am experiencing the difference between a hardwired 2.0 amp charger (it works) and even the Samsung charger, adapter with USB, that is supposed to be the standard (does not charge while in use and is very slow to charge when powered off). May have been a coincidence, but I have to wonder.

    that's really a big effort to come to a conclusion..
    the point is clear "INSERT YOUR CABLE CAREFULLY WHEN CHARGING" or else..

    I purchased two 10.1's GT-N8010 in 2010. They have both been great untill the last few months when the batteries ran out quickly and started charging very slowly. They were using ICS 4.0.4 but I realised the problems started after the update to Jellybean. I have even purchased and installed new batteries but the problem is still there. Obviously something internal does not go well with Jellybean. I am searching for the old ICS stock rom which is impossible to find but I will keep trying and let you know what happens if I manage to find and flash it.

    If anyone else has tried this or has the ICS stock rom please let me know.

    After much testing of a variety of AC and 12VDC adapters, it appears that some Samsung tablets require a proprietary charger or adapter similar to Apple.
    All AC adapters I tested gave the red crossed charge icon unless they were Samsung of 2A output capacity.
    All 12VDC adapters I tested gave the red crossed charge icon regardless off output capacity (2A & 3A included.
    Adding USB extensions did not cause the red cross in any combination, including extra thin cables, with 5 different cables strung together in series. Total length of over 3m still works fine with the correct 2A adapters.
    BUT, adding a dongle supplied by Targus gets rid if the red cross for all scenarios!
    This came in the "Laptop Car Charger + Phone/Tablet Charge", model # APD046AU
    The Targus website actually mentions "iPad or tablet", so should be good for all.
    Edit: as I do not own any Apple gear nor plan to, no Apple adapters could be tested
