Just got a Tab but I bought it off of someone who couldn't find there charger so I had to find one locally quick and the ONLY store that had it in my area was Verizon but it wasnt a Samsung branded OEM charger, It was a Verizon charger that was suppose to be the same but It doesnt charge via USB and Im wondering if for some reason its not suppose too? It charges USB when the Tab is off but when its on it doesn't? I can only charge it via wall charger when its on? So, is That normal? Or, does the OEM USB charge it while its on and this Verizon one is just messed up? Thanks.
Yeah. I got the Samsung Charger. Charging through USB from a computer is super slow to useless.
Only plugging to a wall provides sufficiently speedy charging.
The Tab is quite greedy for power and using either the USB port on a PC or a low Amp rated Mains USB charger will result in either the phone charging very slowly or not responding whilst under charge.
Charging the Tab using the USB and a PC, well there's nothing you can do about it as the USB standard only distributes 0.5 amps (500 milliamps) of power through each port.
Mains chargers however are rated higher but most common one's only have a Max of 1.0 amp.
What you need is a charger that has the capacity to deliver 2 amps.
Check Google & Ebay, there are a number of chargers available rated at 2 amp.
So usb charging while the tab is on is impossible, right? The charger charges fine plugged into the wall, I just needed to know if it not charging via usb while the tab is on was normal, and from what I get from what your saying is that it is normal, it will not charge usb while the tab is on... thanks.

No, I didn't say it was impossible. I said charging via the USB port on a PC will either be very slow or may not respond whilst under charge, it's certainly not the best method. It's just that with only 500 milliamps of power trickling through the USB port, the second you start to use the Tab in anything that requires a decent amount of power you are not going to get any charge.
The only way I find an ability to charge the Tab under a USB connection when connected to a PC is to let the screen on the Tab turn off and not to touch it. It will still happily communicate with your PC and send/receive data but it will take a much, much longer time to charge that's all.
I gotcha, so...when my tab is on it says not charging in the status but if I let it sleep it actually will just very slow... I understand what your saying and thank u for your time, I just wanted to make sure it wasn't the usb cable I got to know to take it back or not...

I charge mine at night via USB to my computer. Starts around 20% by the time I plug it in. I don't power off the tab. Always has a full charge in the am.
I have a double usb cable that is used to power an external drive. I would need a female to female adapter, but this should provide more power to the GT.

Yes, providing the cable you have charges when using with a mains plug then yes, the cable is good.
If however the cable did not charge even when using it with a mains plug then definately you would have a sync only cable.
Thanks, I'm just gonna let it sit overnight with it on sleep n see what happens

To charge through your PC with official USB cable, you should make your own USB "bridge"as short the data wire while insert an 33K om resister between gcc and data wire, an 10K om resister between gnd and data wire.

Yep... I left it on the usb in sleep and it did charge so the cables fine, It just sucks that it doesnt when the tab screen is on but oh well... If theres any solution to fixing this that it charges well from usb then let me know, I know someone just commented about modding the cable to work but theres gotta be a better solution...
Sounds like u bought a stolen tab. No charger or box?

just used a spare double-headed cable from a portable hdd that fortunately has a full size usb plug on the other end. (Most have mini-usb at the drive end)
I use it with a female-female usb adapter and it works pretty well for the PC, particularly on USB 3.0 ports.
I also saw these on Amazon:
amazon dot com/Apricorn-Power-Adapter-Cable-AUSB-Y/dp/B000JIOHDE
I believe Blackberry do one for the Storm as a standard accessory as well
For the car I got a car charger designed for iPad with a USB socket that delivers up to 2.1A
Belkin has the car charger

(I should say, I don't actually have this one, mine is a generic brand that also has a 1A usb socket)

no need for all that, just plug it in computer USB and wait it take sometime but it charge, because pc USB are not powerful enough to feed 2A to the tab.

That is the limit of usb on a computer. If you want a fast charge you need to charge off the wall.
Wait for kernels that pump up the charge. (not recommended)

True enough; I just gave the maximum amperage you can get out of USB. Probably should have been more specific.
Something like this might solve your issue...
http://www.amazon.com/StarTech-com-USB2HAUBY1-Cable-External-Drive/dp/B0047AALW6
Not sure I would be willing to try it myself though.
Lol, yesterday I put it on charge at 20%, checked it after two and a half hours, and it was at 55%. I have USB 3.0 on my cabinet/MoBo, but just need to find out which one is it, but how do I do that?
This is a known issue on almost all Samsung phones that most people here aren't willing to acknowledge. The USB spec allows 500mA, but Samsung designs the recent phones to only pull 96mA. Apparently some of the modified kernels correct this.
Just be glad it's not like my old Samsung Focus. It would only pull 50mA which was less than the screen consumed. If the battery was totally dead, that phone was impossible to recharge via usb because it would auto-boot after you connected it, which would immediately consume the small charge it had acquired, thereby dying again.
Anything you charge off of a usb port will take forever.

Yes, that feature is included in a number of Asus devices, and it works really well. It's included in my Asus Sabretooth Z77 motherboard, and also on my Asus Diamond router (which has 2 USB sockets).

Why are you guys in such a hurry? I thought that it was best to charge the battery at the lowest possible amps - and the maximum should be 2amp/hour with the wall charger... so, as often as you can, charge the battery from usb, so that the battery lasts longer...?
- Bobo
Or just get a spare USB cable that you dont use to often. Short out pins 2 & 3 to force the phone into AC charge mode. You just wont be able to use that cable for data any more.
http://forum.xda-developers.com/showthread.php?t=767961
I was thinking about doing this or at least purchasing one online, but not sure what needs to be done, do I short out the CABLE or do I short out a USB port on a car charge? I read on a different thread that a guy who drives for 30 minutes, increased his charge from 15% (unmodded) to 30-31% (modded) and I think he did this to the USB port in his car charger, but not sure

I won't charge mine via the USB port..takes too long. Top off, is ok. Complete charge...no way. The N7 has a big battery, so I use the AC charger. 5 hours via USB (dead battery ???) doesn't sound too long to me. Most USB devices only charge at some low rate...like 500 milliamps. You should be using, at least, twice that.

Correct. Laptop ports are around 0.5 amps, the stock wall charger is 2 amps
Of course it will charge slow over USB. Plug it into a wall if you can.

If you look at your Asus supplied Nexus charger you'll see that it's rated at 2A the N7 will happily draw all of that to charge. A pc or laptop usb2 port can supply a maximum of 500mA, that's only a quarter of what the N7 needs to charge at decent rate and you can damage the usb port by putting too high a load on it. My advice is to charge your N7 via the mains charger and forget trying to use the usb port, get a second charger or a portable battery pack if you need to charge while away from home (see the thread on battery packs in this forum for details)
For reference a usb3 port can output 1A if it's set up to do it.
According to Tom's hardware you are still quick. Their graph says 0-100% on usb, screen off 10 hours.
Is there a setting I need to enter to get the fast charge rate to turn on? I am charging the Note5 and its rate is at 425 mA with the screen off. My Note 3 Charges at 1800 mA with the screen off. I've switched outlets to see if it would help, but no.
How's everyone else's charge rate?
It's automatically as long as you using the Samsung original fast charger... Also check how long the full charge take.. Should be maximum 90 minutes

Try switching the charging cable with another. When I got my Note 4 I had a similar issue due to the cable.
Try turning your charger around in the wall. With my s6, it won't fast charge if the polarity is backwards.
Very true. I had some aftermarket much longer white cables, and they are SLOW. I just changed by Tab S to a shorter black cable that probably came with a charger I got, and it is charging normally. Odd that a cable can be slow, but it can.
I did not use it yet. How can i understand its charging first ?
I have tried 'A1 SD Bench' to test my Note 8 with a 512GB Samsung T3 SSD.
The best results I can get is:
Read: 33.42MB/s
Write: 35.57MB/s
I have tried the following connections:
- Direct USB-C to USB-C
- Note 8 <-> USB-C all-in-one hub <-> USB-A to USB-C cable <-> Samsung T3 SSD
- Note 8 <-> Original Samsung USB-C to USB-A female <-> USB-A to USB-C cable <-> Samsung T3 SSD
Any ideas how to get full USB 3.1 transfer speeds?

It charges slow but it's very consistent at temperature management. The device does not heat up like the ones using other fast charge technologies. I just read a comparison article and Samsung's version is definitely not the fastest, but it's definitely one of the cooler ones.

The OP isn't asking about charging speed, he's asking about data transfer over USB.
I have USB 3.0 and 3.1 type A ports on my desktop PC and using a 3.1 Type C to Type A cable it's very clearly much faster than using the cable in the box, which does appear to be usb 2.0 wired.

Yeah I rarely use my phone when it is charging. I use pushbullet on my computers so I wont miss a text or call. I compare the charging speeds of Note 8 to the Note 4 in the morning charging. The Note 8 will not be charged in an hour whereas the Note 4 easily did it. Sorry OP. I'm done.
That brings the question: how do you tell which cable is really wired for USB 3? And what's the difference? Wires have to be the same, is it just shielding? I would imagine due to higher frequency, if signal is not clear it would negotiate lower transfer rate?
I have couple USB wires from Note 7, maybe those are better made?
And is the phone really capable of accepting data anywhere near full USB 3 speeds?

I found an article that states USB-C hubs downgrading speeds to USB 2.0 so I guess thats one of the main reasons the DEX is also limited to 2.0 speeds.

I however cannot get USB 3.1 speeds even when using a direct USB-C to USB-C link.
If the Note 8 is not capable of utilizing the full speed of USB 3.1 speeds then I'm quite disappointed.

It turns out the USB-C to USB-C cable I got is not usb-3.1 spec:
https://www.amazon.co.uk/d/B06Y4N4K9Z
The USB-C to USB-A cable I got that came with the Samsung T3 SSD is definitely USB3.1 spec so Samsung USB-C to USB-A female adapter is probably USB2.0 speeds.
And according to the article going through a hub also limits the connection to USB2.0 so I'll either need a new USB-C to USB-C 3.0 cable or USB-C to USB-A 3.0 female adapter to do further testing.
