Did a quick search but not seeing any threads. HUGE issue .. can the S7 be charged via USB?
I installed the Nero software Dell sync and stil not working.... about to call Dell and get this sorted but wanted to ask here first.
UPDATE:
Called Dell support and USB charging is not supported on this mobile short battery life device. Back to Dell it goes. Pathetic.
it is via the dock.
Is he serious ....i guess so

It only does not charge when usb is plugged into a computer.
It charges fine when I plug the USB cable into the wall adapter plug or into my car aux socket.

Like all tablets must have 5 volts 2 amps not 1 amp like a standard USB port. Will charge on USB when turned off.

Works fine here and has since it was released.
Yeah worked here too. Have to power it completely off though not just shut off the screen. Still fail IMO. Sending back for now, maybe get a revision down the road.
Thanks!

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
belkin dot com/IWCatProductPage.process?Product_Id=525940
(I should say, I don't actually have this one, mine is a generic brand that also has a 1A usb socket)
cheap chargers....

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.

Hey just a notice. I just had my DS7 charging while I was downloading the 400 mb game Monster madness. I was using the USB adapter for AC that my Zune uses. Seems to charge on and off and after I checked after awhile, the USB adapter got hot. Same thing happens with a couple other USB adapters to AC I tried. So it seems you may have to use the adapter that comes with the DS7.
Anyone else notice this?
Any 5 volt 2 amp USB charger will work. 1 amp chargers will run it but not charge it.
Sent from my Dell Streak 7 using XDA App
Ok that is indeed the issue. The OTHER usb adapters I have (The ones I have at work) are all 1000mA which then my warning continues. It DOES charge it by, but it does so in what seems to be a bad way. It charges and goes off back and forth, so its like a trickle charge. But it does make the adapter very hot. Either way, not good to use a 1000mA adapter then it seems.
If you use a 1 amp charger, just power the streak down completely.
Sent from my Dell Streak 7 using XDA App
Yea thats what I do when I need to charge it at work, just dont leave it on while charging. Unless you wanna smell the burning of it after awhile from the plastic adapter.
I have a question for the xda community hopefully you guys can help me out: ok so i have been charging my tab in my car using both the cigarete lighter and ac outlet, but i have noticed that it discharges faster than it charges, for example if i am using the gps while charging the tab the tabs battery will drain. On the other hand if i am charging the tab at home on a regular wall outlet it charges fine. In comparison my samsung galaxy s charges fine in the car via the cigarete lighter. I am using the original charger that came with the tab. Any ideas as to why it drains faster than it charges? Thanks.

The Galaxy Tab USB port is wired slightly differently to other USB ports, which results in only getting a trickle-charge from regular USB cables. You need something like this...
http://cgi.ebay.in/USB-car-wall-charger-adapter-plug-Samsung-Galaxy-TAB-/190522553195
I can't vouch for that particular seller, but I have one of those adaptors and it makes all the difference when plugging into anything USB.
Incidentally, when you say you're using the charger that came with the tablet, are you saying that it came with a car charger? I've not heard of that before.
Check the output of the charger. It should put out 2000mA. It should be written somewhere on the charger.

I had read that the port was wired differently. Thanks for the link into ebay for the charger adapter. For the price, it's worth checking out.

Charging my Nexus 7 is taking over 5 hours via USB.
How long does it take for everyone else, and if this is broken, what is the process to get it replaced ?
Also will Google replace the battery/hardware, if i've changed my ROM ?

What kind of usb? wall charger, usb 2 on computer, usb3 on computer?

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.

You will get 3 times the current from the stock charger/cable than from a computer's USB port.

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.

Not really its just standard USB charge rates they don't charge as quick as originally are only need a little bit of power for flash drives and so forth. Nothing will charge quick via USB.

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.
Would prefer a dual usb but what is the best in ur opinion? (Sprint 7.0)

Yes, it should, as long as the vehicle power outlets and usb chargers are operational and provide the correct voltage.

Hmm. Maybe there's something up with my tablet then. I found a YouTube video for the tab 10.1 that showed to plug the USB cord in just slightly to where it makes a connection to charge, but isn't fully inserted to make the data connection. This trick is working for me with the USB PC connection and car charger. It makes me think there should be a way to change a setting or something to always make it charge when plugged in.

Same here. Mine won't charge either
Sammy has been guilty of moving around power lines on their devices so that only there chargers and usb cords will work. Galaxy 2 phones and a few tablets won't charge on OEM or other manufactures cables.

I don't have the problem. I use a belkin dual port car charger... one is 2.0A ... the second is 1.1A. Charge my note 3 and tab off the 2A plug. I can tell you the tab wont charge on the 1.1A... but the Note 3 will just super slow.
I have a Lenmar dual USB car charger that is 2.1A per port. That "should" charge it, but apparently Sammy blocks it. I wish there was a workaround in the firmware.
