Hi Guys,
I'm just wondering if my unit is defective or it's really the case for Galaxy Note 8's. My tablet charges just fine when using the wall charger, but when I connect it to my PC, it won't charge at all. I've tried different cables that I use for my phone and other gadgets, but none of them will work.
Is there a way for me to make it charge via USB?

Mine also says not charging when its plugged to the PC, its because the USB ports supposedly don't give enought current to charge the tablet, but i once left it connected overnight while transfering my MP3 collection and in the morning the tablet was 100% charged, so i think even if it says is not charging, it charges but ultra slow, even slower than a cell phone.
USB ports on a PC does not put out enough voltage to charge the tab. Like said above, if it does, it will take forever. Look on the back of your wall charger. It should say 10v. USB ports typically put out only 5v. If you look on the back of a phone charger, it should be 5v.

It's not the volts, it's the amps. Your charger provides 2A. A typical USB port provides 0.5A. But in any case, you'll not be able to charge this device from a computer USB port. It's not a fault in the device.
That explains it then. Thanks guys :laugh:
Hmmm... I alway charge my note 8.0 thru my pc usb.
It charges on my pc and lap top.
If you want to be sure just let is sit for an hour and see if the % went up.
Doesnt charge fast but charges in an evening from 60 to 100%
Perhaps it doesn't charge while the screen is on, because the power drain exceeds the charge rate? There would be no way to see it change to "charging" because the screen must be off for that to happen... Just some speculation

I have a HP Envy M6 laptop that I use to charge my Note 8. It only charges on the port closest to the battery. The only USB 2.0 port out of 3 other USB 3.0 ports which is odd because they say USB 3.0 ports give out more power.
I have tried charging it with another HP laptop that has the same USB setup but it doesnt charge in any one of the ports, 2.0 or 3.0.
I guess it just depends on the PC you're charging it with.
Can charge.
hi,
We can charge note 8, if the note is switched off and connected to a PCvia USB
Normally Note 8.0 can not charge with pc usb port or car usb port because AC current of them too low only 0.5A (minimum AC current of charging require should be 1A)
Samsung Tablet stock charger is 2.1A (Note 8.0 device allows 1.8A)

I am considering buying this usb charging adapter cable to help speed up my charging rate at work where I don't have an AC adapter and my work computer's usb ports are conveniently placed. From what I have read, normal usb charging maxes out at 500ma, but can be increased if your usb port has more juice if you short the data wires, which will tell the phone to grab more power because it thinks it is plugged into an AC adapter.
I have found this adapter http://www.dealextreme.com/p/usb-data-charging-extension-cable-for-samsung-p1000-black-91141
it is meant for a galaxy tab, but From what I see is that it has a switch that either allows data / slow charge or allows quick charging. I have purchased a few of these already because I'm assuming it will still work with my galaxy s2.
I'll let everyone know how it goes, but does anybody see a problem with this or think I'm going to fry my phone for any reason?
Thanks.
very interesting, heck it's only $3 bucks, might as well just buy it and find out
yes, charging via USB port sucks, it's too slow at 500 mAh
if that does the magic trick, by shorting it and making it believe it's an AC then it'll be nice, and it can pull around 1000 mAh off the USB port (depending on your computer mainboard)
Id be curious to see if this actually works but i see no fault in trying it

Only the Galaxy Tablets have this limitation (they cannot be charged at all via computer usb only via their "special" wall adapter) so the adapter won't do anything for a phone. The adapter works on the tablet because what the adapter is doing is shorting 2 pins on the USB cable to fool the TABLET into thinking it is on the AC adapter "specially made" for it.
As long as you plug the phone it into a self-powered usb port (ie: a hub with a power brick) you will get max current the phone allows. The adapter will make no difference on the phone because the phone CAN charge off the PC port while the tablet cannot. It won't hurt the phone but it won't help it either.

Thanks for the info on the galaxy tab, however I disagree with you in your opinion that an adapter that shorts the data wires will not help the phone to charge quicker.
It seems either the devices or android system itself limits charging to 500ma so it does not damage the computer, the phone itself knows that it is connected via usb, and will state "Charging: USB Plugged"
If you let the phone think it is connected to an AC adapter, it will allow the battery to accept whatever amperage you throw at it, and you will see that the system states "Charging: AC Plugged"
Obviously there are two modes of charging going on here.

Has anyone tried this yet?
I have found that using the Galaxy Tab chargers works the same way. They have a 2amp output vs the .5 amps that most blackberry chargers and USB use... It shortens the charge time significantly.

Charger considerations
Hi,
I need advise for the following:
Charger A (Li-polymer battery) output : 5V, 1A
Charger B (Li-polymer battery) output : 5V, 500mA
Device input: 5V, 750mAH (Li-ion / Li-polymer)
When using Charger A, some people comment that it will limit the current of 750mAH for the device and the device's battery should be fine since both the charger and device are at 5V. However, some people comment that this will shorten the battery life of the device since it will perform a 'quick charge' using 1A.
When using Charger B, some people comment that the device will draw more current than it can deliver and causes it to heat up and reduces the charger's life. However, some people comment that Charger B will extend the battery life of the device since it performs a 'slow charge'.
I also read that USB pins on the charger denotes if the charger is a PC or a dedicated charger. If it is a PC, the device will limit the drawing current. If it is a dedicated charger, the device will draw more current to charge itself.
I am confused as to who is right and which charger should i be using.
Can someone enlighten me ?
Thank you very much.
Guys, I have my normal charger at home which works fine. Here at work I have a fairly new (but cheap) USB cable. At work the charge never goes up, it stays at the same percentage all day. It charged my Optimus 3D fine.
If I swap it for a colleagues USB cable (came with his Windows Phone) it charges fine (same USB port or USB ac adapter).
Is there a certain type of Micro USB cable I should be looking for that's not stupidly priced? (in the UK)
Coming from an Iphone I didn't have any spare micro USB cables so I went to a computer store and bought 3 store brand (cheap) microUSB cables and they all work fine.
The only thing to take note of is some wall charges are seen by the phone as "USB" and not "AC Charger" and thus will only pull in 500mah which is pretty slow. If you install battery monitor widget by 3C it will tell you the amperage coming in and if the phone sees your connection as USB or AC.
I discovered my 1amp apple USB brick does not charge higher than 500mah only my samsung one does that came with the phone.

yeah, but if I use the same USB port or the same AC plug I don't understand why 1 cable will charge fine, the other gives just enough to keep it at the same percentage all day?
Hey all. I finally got my Note 3. I have been using it for a couple of days and, of course, it is awesome. But one thing is troubling me. I charge my phone via my desktop PC, which has several USB 3.0 ports. I first plugged it into the ones on the front, and it wasn't charging very quickly, so I plugged it into one of the back ports, and i'm still having the same problem.
For example, last night, I plugged it in around 1am at about 30%. It's now 7:30am and its at 96%. I would have figured it would be at 100 a while ago. I am using the original Samsung USB 3.0 cable that came with the phone.
I'll have to do a more scientific charging test to see what's going on, but has anyone else seen this?
The supplied charger puts out 2 amps. Which is much higher than any USB port on a PC will ever provide. That's why you're seeing such large disparities with charging rates.

A computer's USB 3.0 port is only spec'd to put out up to 0.9amps, compared to 0.5amps for the older USB 2.0, but the A/C charger puts out 2amps, so use that when charging time matters. I never use a computer's usb port for anything anymore except adb sideloading in recovery (where adb over wireless won't work). Note that SOME computers do have non-standard higher amp usb ports, but it's not that common.
ah I was also wondering why the charger itself charges the phone much faster than my desktop. Good info, thanks guys!
I have bought this item from ebay, it work great and charge the phone very fast

Thanks for the responses people. I will use the plug from now on.
The charging speed will definitely slower than..?
It is the normal case that the speed will be much slower when you charge a device such as your Note3 via USB than via DC Power Supply. USB is mainly designed for the communication. The standard charging current of many mobile phones is 1 A or higher. But the highest output current of USB cable is only 0.5 A which could not reach the source demand of a phone. Except for this, we do not recommend charging via USB because the unstable current output can easily reduce the battery life of your Note 3.:laugh:
I've had some trouble charging my new tablet.
When I first received the tablet, I plugged it in to the supplied cable and allowed it to charge to 100%.
I used it for a day to run the battery down.
I then left it plugged in to the computer with a standard cable for 11 hrs.
It appears that it didnt charge at all.
Now I drove all the way back to my office to test it again with the factory supplied cable and it does appear to be charging slowly but it is totally discharged.
I've experienced intermittent issues with charging. Seems like it prefers but doesnt require the samsung charger/cable. Are the voltages and everything the same?
Yeah, seems like it wont charge on a usb port. Only seems to rocognize the supplied samsumg charger...

Do you see that the battery icon has a red X over it when you have it plugged into the computers USB port. The tablet needs the power that the supplied Samsung charger puts out to charge that big battery.
On page 9 of the users manual it says "Note: You cannot charge the battery using the USB cable and
your PC"
.
so is it just a 2A usb charger?
When it's got the red cross over the battery symbol (when it's plugged into a computer USB or car charger etc) it does still charge, but very slowly. Probably only with the screen off.

It charges with any standard charger. I use non-samsung charger and it charges fine, in fact I have not removed the original charger from the box.
As with USB it does charge but really slowly, while it shows not charging.
I believe that a standard USB is 1A and the note 2014 is 2A. Can anyone confirm?

Yes, this is correct, my standard Galaxy S4 is 1A, however a computer may put out even less than this.

No. Standard USB 2 port supplies 0.5A. USB 3 port will supply like 1.5A or less. As for USB 2, you may install (if motherboard supports it) ASUS Ai Charger so that it supplies 1A.
I have gigabyte mb and it has its own driver to over supply usb 2 current. With that I have about %6/hour charging rate if screen is off. Using Samsung own charge, I got about %24/hour.
PS: Look like my desk usb 2 port supplies .5A only (%6x4=%24).

Not to be rude, but what you wrote here makes no sense to me .
i got the charging issue also, with original charger 2A, original USB cable
checking with galaxy current, value at 900mA
my tablet charges perfectly with original charger and cable but using every standard usb charger (2A and 700mA) it charges but the "connection" is unstable: it's like usb is connecting and disconnecting repeatedly.
I've checked every connection, using the same charger and cable with another phone the connection is stable.
Anyone with the same issue?

My 6 day old Verizon Note 4 stopped USB charging last night.
Went to bed plugged it in. Woke up this morning only at 50%. USB not working. Plug into supplied charger via wall socket, charges fine. Plug into computer charges just fine. Does not charge via USB in my car. Still need to check my cig lighter charger. Any insight? Should I go to Verizon and swap it out?
Thanks,
Bill

I would think that is the best way. Your computer and your car charger should be the same and your pc is working but not the car charger. I would get the 2 amp car charger at the least, not the 1 amp one. Also remember that if you charge with PC or car, you can't use your phone while charging or it would rather drain your battery instead of charging due to too low amperage.
All the same stuff still works on my note 2. My note 4 just stopped usb charging...is it the phone?

Is your car charger is the old car charger with 1 amp? try to power off your phone then plug in and see if that works.
Yes it is the old charger. Need to get it out of my wife's car. Will check in the am.

Did you get the red X in the battery icon? To verify if it's slow charge, you need to go into settings->battery and it should indicate that if it slow charge, if it said no charge then you need to get a new one and make sure get the 2 amp one for none Samsung charger or get the original Samsung made.
My car charger is a 2.4 amp dual charger. It still works with my Note 3, but has never worked with my Note 4. I tried plugging the phone into my radio which pumps out 600 MAH, and that does work. I tried turning off fast charge and my 2.4 charger refuses to work.
First I just want to say I'm no expert, but I have been around the block regarding car chargers and chargers in general.
1. The amperage is important, however there is also voltage that needs to be considered.
2. I've seen chargers that say on the device that it is 5v and 2a, but when you actually take a multimeter to it, it's not outputting the proper volts or amps.
The note 4 has 2 charging modes.
Regular - 5v and 2a
Fast - 9v and 1.67a
You will want the charger you're using to match one of these volt and amp combinations to properly charge your phone.
I have had no problems using all my note 2 chargers (5v and 2a) for my note 4.
I hope this helps.
