I'm having an issue,and seems not just me,that I can't charge the Tab via usb connected on a laptop or a Mac book (pro).
I'm wondering if its firmware related, I've tried JID and JI6 same issue.
Are you guys having the same?
If someone is not having this problem can please be so nice to tell me the firmware version?
Thanks
no, you cannot charge the tab from a PC usb slot cause of some minimum power requirements which was the same way with ipad

No is not the same than ipad, ipad is possible to recharge with new macs (that what apple says on the web site, the don't say how new though). But is true the iPad has 2A battery versus the Galaxy Tab that has 4000mAh, I was hoping that there was a way to recharge it (slowly but at least to keep it alive when is connect)

hi guys,
mine is also showing the non-charging-sign but it charges slowly - get juice plotter and try it your self

Mine is the same guys... I left my AC charger at work over the weekend and have been charging it via USB the whole time... Slow but it gets there if you leave it on over night!
Mine won't charge unless I use the power adapter from Samsung
Mine does charge but slowly from USB.... you should also know that different PC boards and laptops have different power outputs.... in most cases, your tab should charge very slowly on USB power. Mine charges and has BT and Wifi on also... but with heavy use and plugged in to my laptop, it may offset and drain ever so slightly....
Same thing goes for car chargers... if not rated for higher output, it will charge VERY slowly. The original Samsung car charger has a much higher power output. If you can find one that has the same aftermarket USB car adaptor for Ipad charging, that should work too

The contacts on mine are upside down compared to an iPad/iPod/iPhone charger. The blade on which the contacts sit is also higher in the charger slot than an iPad charger. How did you get it to fit without breaking something?
Some PC:s (motherboards) have so weak power output via USB, that they just barely provide a mouse and a keyboard but nothing more.
So anyone should not expect it to be enough for charging Tab.
Tab's own power supply gives 2 Amps out!
My experience about car-usb-adapters: one can charge Tab, other quite similar for some reason not. However, both charge Galxy S fine.
Just something to keep in mind as an option... Usb 3.0 will give more juice to usb cables than current usb ports. Apple has "cheated" and already increased the power to the regular usb ports on their newer laptops on par/better with usb 3.. So... If you get usb 3 cards installed you'll have a port with enough amps to charge the tab. Easier/cheaper to just buy a pdmi cable but if you are about to upgrade to usb 3 its more incentive to do so.

Regarding the ipad charging you can use the below link to to download an ASUS program that will boost the USB power for Windows this works for the ipad and it's showing as charging when connected to my PC this may also work for galaxy tab

Charging using usb on my mbp does take a long time. I timed it and it took at least 6 hours to charge from completely empty to full. Its ok since I plug it in when I'm about to go asleep and by the time I'm up its fully charged.

Careful with that.
Seems it has the not-uncommon tendency to screw up USB drivers to the point that mice and keyboards won't work either, especially on Win7 and Vista X64 machines. It got me, had to do a system restore to fix it. Neat idea though.

USB port should give at least 500mA. But anything more is OK. So Apple can make their USB ports to give anything over 500mA and it is well within the standard. Actually it is good for everyone because if Apple port can give 2A you can use non powered hubs and have power for lots of USB devices.
Actually the Tab charges fine (albeit slowly) from a USB, you just have to be aware of a few things. Firstly as mentioned above some USB ports provide more power than others. Try the different ports on your machine and you'll soon figure out which ones work best. Secondly, while the Tab will display the "Connect your charger" message, it is actually charging. Go into Settings, About Phone, Status and watch the battery level. It'll take a while but will creep up. Finally, it charges faster when the Tab is switched off. ie: if you're actually using it, you won't get a charge, if you have it in standby with screen off, it'll charge slowly (takes most of a day for a full charge) and if the Tab is switched off, it'll go a lot faster (though still not as fast as with the power adapter.)
This is good to know as you can plug it in to your computer and let it set on your desk at work all day and know that it is slowly trickle charging.
I also found that plugging the USB cable into an Apple adapter (from an iPhone) brought up the same "Connect your charger" message, but did charge the Tab, faster than a USb but not as well as my samsung plug.
Hi, I've been using a note for about a month and a half now, and all has been well.
Until about two weeks ago, when my phone started charging very slowly via USB. Using a 2.1amp charger, it takes about 4-6 hours to charge, and about 7-8 hours using a 1.1amp USB charger. The less said about 0.5 amp chargers the better!
However, when I'm charging using a 1.1amp charger (Standard USB output), often when at 15 or less percent of the battery, if I still use the phone while plugged in, it actually drains power faster than the USB port can provide it! It will often shut itself down and give me a "extreme low battery" screen, meaning I can't turn it back on until it has some charge in it... which can take up to 20 minutes via the same USB port/wall adaptor
Running stock 2.3.6, unrooted.
You could have a faulty or dirty micro-usb port or a faulty battery.

I have the same problem. My Note is new and I don't think the battery is faulty
With stock ICS in comparison to GB, it consumes more juice thus takes longer time recharging.
This is normal, but sad.

Same here
I have the exactly same problem and ended up here, while searching on google if there are othere with similar observations. I can as well comfirm that during playing certain games the phone looses charger faster than it can be recharged.
Beside that my phone overally looses battery much faster than it used to be.
I found out that you can recharge the phone considerably faster when it is completely turned off.
[edit:] The problem started after the update to Android 4.0.
Now I have no way out but to root my SGN running stock ICS that allows me to do more customization.
I am using SetCPU to limit CPU clock at 1200 MHz (from 1400 max). Only certain apps really requiring CPU power, I specifically allow them to run at max MHz.
This helps reducing recharging time a lot...a lot (even much faster than charging when on GB) and allows more time in outdoor uses. And there is no lag.
Sent from my GT-N7000
I've found the total opposite, I find charging in ICS (Stock not a custom as I've not tried one) to be loads faster at charging than in Gingerbread.
What programs do you have constantly running? The more that's running, the more juice it's gonna use and therefore the slower the charging will be.
How long does it take to charge with the phone off?

Same problem with charging as well.I an using ics 4.0.3 cpw version and it draws more than it gets from the usb charger.
I also experienced slow charging before.
What I do is to close all the applications and see if that works.
Same thing happened wid me... Its Kernel fault.. Try changing kernel.. It will help
Noted by the BEAST!!
Look for runaway tasks consuming high CPU and maxing out the CPU clock rate. You can use a CPU monitor like System Panel Lite, and also simply feel the phone at the rear near the camera. If it is hot you have a problem of some process going nuts.
This is a classic problem I've faced on ICS and I've given up with it and gone back to GB. No problems since.

Just to clarify, a standard USB port on a pc/laptop can only provide 500mA not 1.1amp. Not sure where you got this value from. Therefore it will not provide anywhere near the required current, especially if you are actively using the phone. Most cheapo car chargers are also innadequate at 500mA. The standard sumsung wall charger only provides 1000mA.
What 2.1Amp charger are you using? Its not recommended to use more than the standard samsung charger outputs !
You need 1000 mA (1 A) charger for proper recharge even on GB.

1A is the standard Samsung charger.
So is it okay to force the note to use the 1 A ? standard it is set on 700mA
You can adjust the charging control with Voltage Control
I too started having this problem yesterday after updating to a recent version of Visual Voicemail Plus. Even charging from the wall outlet could barely keep up. Turns out the problem was VVMP continually polling NON-STOP for voicemail. Reverted back to older version and problem ceased immediately.
My point....your problem might be software and not hardware. I'm still on rooted and overclocked GB with franco.kernel.

I'm using non-data cable to charge via usb port, it's way faster. Only cons is that u won't be able to transfer any data.

I have been using HTC & Samsung wall chargers, Belkin 1A in car. All chargers provide fast recharge. However, the quality & length of USB cables are crucial.

Just to clarify things, the 2.1amp charger is a USB battery pack, and the 1.1 amp charger is a USB wall adaptor. I'm running 2.3.6 GINGERBREAD, unrooted.
There are two charging rates, slow via the USB data cable, and faster via the charger (where the D- and D+ pins of the USB are shorted). If it thinks that you are using a computer USB when you are in fact using a charger, your charging will be at the lower rate.
I had this problem of slow charging and the cause was a dirty connector, get some electronic connection cleaner from an electronics store and spray the USB connection and cables - that fixed my slow charging problem.

I'll give that a try, thanks

I don't know , but I think even if you were able to charge via usb it will took very long time in order to full charge it because capacity of battery is big
Need to make your self a universal usb charging adapter,look it up on here.
Works and been tested with 7.7 aswell!
You need to solder resisters 33k and 10K To the data and power lines...

Do you mean D+ and D- lines of USB need to be pulled up ? and which D line should have 33k or 10k ?
Link please .
yes thats the one..
(make sure you join the resistors to each other at the middle aswell.)
Look at the resisters you use and make sure they are both facing the same direction.My first attempt to do it failed and at first i thought it didnt work on 7.7
Then i noticed one resister was back to front.not 100 percent sure if this was the problem but after i changed this from looking at pictures online and comparing the pics to my resisters i noticed what end the 2 colored bands are at.the 33k one with the gold bands and the 10k one with dual black bands.
The end of the restister with the gold bands(33k) and Black bands(10k)
is the end that the power joins to.
The other end of the resister should have matching bands on 10k and 33k.
this is the end that joins to the data line.

once i left my turned-off 7.7 connected to my running PC for few hours, to my surprise the battery seems to be charged-up during that time
yup... its still charging... but slowly...
Actually you could get faster charging with that USB data cable when the PC has been installed with the proper drivers. The standard downstream port could deliver up to 500mA ONLY after the USB hub has negotiated power draws with the host interface. Otherwise the port might just deliver less that 100mA power.
Kies provides the suitable driver. You may uninstall Kies afterward and keep the driver installed.
In addition, PCs have two kinds of USB port — standard downstream port and charging downstream port. Some older PC would label them 'SDP' and 'CDP', but I found that most modern PCs don't distinguish them at all. As you might imagine, you could get faster charging plugging into a CDP than into a SDP.
FYI., those ports used in wall charger is the third kind of USB port, CP - Charging Port.
Hi!
After installed the Battery HD soft, when link with PC, That programe showing the charging time and progress charge. but still not sure.
I am charging via USB as we speak.
I am doing it using a standard mincroUSB cable (that I use to charge my GNote and SGS2) and added an adapter I got on eBay for my SGT10.1
You can pick one up here: http://goo.gl/EMzpJ
It's not as efficient as the AC charger but it's doing a good job and will get you by if you haven't got access to a power point.
Can use this hub to charge as well
This SIIG INC - SYNC/CHARGING HUB AND READER FOR GALAXY TABLETS - CE-H21112-S1 gives you the capability to charge your Tab through a computer USB port. Seems to work pretty good used it last night. Checked the net prices vary per vendor.

The connector on the 7.7 tab is exactly the same as on P1000. There is no trouble in charging.
My original cable came with the tab allows me to charge via USB @ my laptop, but the charging speed is very slow. So I prefer to use an external portable charger over this most of the time. Not sure if there are any apps or software that allows fast charge kinda stuff?
So i love my nexus 6 because i can fully charge it in less than 2 hours with factory charger.
i also use a 28aw usb port and it makes it even faster with the factory adapter.
with all these new phones that are coming out (n5 2015) and supposedly they'd be using USB.C, does that mean that charge time will improve even more than quick charge 2.0 or would it stay the same? Is USB.C mostly faster data transfer or will it be "quick charge 3.0"?
Would someone explain it to me as i'm dying to find out how much faster phones will charge with USB.C, if any.
Thanks coming your way!
Far as I know USB-C is only the connection. Reversible. Don't have to figure out which end of cable to connect. To change charging rate is internal to device hardware and software.
that is one of the benefits. but from USB's website, it also increases speed from 3.0 to 3.1 drastically so i'm hoping to see some numbers!
It's going to depend on the power management chip that is in whatever the device is.
From my understanding it should also make charging and transferring data faster but not sure how much faster. It will probably be determined by the other hardware built into said device.
can't wait to see what it's going to be like.
universal is the way of the future.
I think how fast you can charge a battery depends on how much current the battery can effectively handle. I don't think it has much to do with the type of connector (usb-c) or the USB spec (3.1)
...except that we're already at the limit of micro-USB with tablets. It's why you have some manufacturers using proprietary charging connectors on their android tablets in order to get reasonable charge times for such massive batteries. The connector is very much a limiting factor after a point.
Whether we reach that point with current battery tech in phone-sized application is another issue.
As far as usb fast charge from a computer usb port it should make no difference. That is controlled by the kernel. For wall and QI charge need the upcoming Qualcom Fast Charge 3.0 that is in the new chips.
Yesterday I've received my Tab S2 8.0". After the first charge I connected the tablet to my computer to upload some files and I get a red "X" on the battery and the message: "Slow charger connected"
In the notification area I get a constant red "Device charging slowly. To charge faster, use the original charger".
Is this normal? Cause I'm using the USB cable that came with the device and tried with USB3.0 and USB2.0 with the same results.
Oh, extra info! The tablet was bought in France, I'm from Argentina.

Yes it's normal.
USB ports cannot put out as much current as a decent charger (like the one the tablet came with). Hence it charges more slowly using USB (or indeed some inferior or lower powered plug-in chargers), and it's warning you that it is doing so. I think the maximum a USB2 port can provide is about 500mA, with USB3 about 900mA or so.
Compare that to the proper plug-in charger, which is 2A (if I remember correctly).
Some motherboards etc do have higher current USB ports for charging etc, but that's non-standard and they are usually specially labelled as such.
Oh, thanks for the help. I got a little scare with the warning.
I got the same tablet, and also noticed this warning about battery charing slowly, and asking me to use original charger.
It's working resonably ok with original charger, though it charges slow with other chargers with the same AMP rating. E.g. it charges slowly with the larger iPad charger, which is also 2 AMP rated ...
Charing with iPad charger is so slow, that when I use the device with during charging, it drains faster than it charges! Quick unusual ...
Anyone? Any comments?
Theres an excellent app called Ampere which gives you info on the tablets charging and power consumption - useful and interesting.
Cant post links yet so just search for it on Play
Also don't forget that (when not built-into the charger) the cable is also important to the amount of current reaching the tablet.
The best charger in the world may well struggle if a long cable with hair-thin high resistance wiring is used to transfer the power into the tablet.
Lastly even though many chargers are labelled as 5v 2A, they may not actually be able to provide that under load, and if things drop when a hungry device like a tablet is connected then things will slow up.
I have a few 5v 2A chargers which come up as slow charging, whereas others which were more purposefully designed (e.g. the 5v 2A charger from my old Nexus 7) work just as well as the supplied Samsung one.

this is such onfortunate ongoing issue
i got my Tab S2 - SM-T715Y in Thailand as i am backpacking Asia ..
I know the warranty is per country .. so I can not use it where I am now - in Vietnam .. or back home in USA
I realized that this was a major factor before buying .. so I can go through my credit cards extended warranty ..
in the future I will buy Acer or Asus or alike that have international warranty ..
yesterday I was on a road trip
and I was using my 12V car charger
and then a battery bank .. and I think it rigered this problem or fact that I drained my S2 to 0%
fact is that now it is showing "slow charger connected" .. I am using the original charger and cable
now it is slowly *discharging* when connected to AC!!
also will try to whipe the cache..
this is so terrible
I am losing faith in Samsung :/ (had charging issues with my Note 3 .. 8 months in .. motherboard issue)
I can not find a solution to this problem
I am thinking of putting it in a refrigirator? maybe it will do something to the battery?
