So I left my tab on the multimedia charging dock overnight only to wake up this morning to the battery still at 4%! I did not turn it off though. Has this happened to anyone? The tablet is 10 days old.

The fact that it didn't completely drain to 0% makes me think that perhaps you didn't use the Samsung supplied wall plug?
The tab does not need to be powered off to charge, however you need to use a 5v 2a wall plug to charge the tablet. It sounds like your tablet was getting a small amount of juice that kept it from going to zero so perhaps the wall unit you used was 1a or .7a?
If not, I'm not sure what the problem was, but I never power my tab off and it has no problem charging with the supplied equipment.
I was using the Samsung wall adapter, but there is a USB cable extender (cable is too short) in between the adapter and the tab USB cable. I will try again later without the extender and see what happens...

I am on the road a lot and don't want to be carrying the HTC charger with me. For my Treo, I had a foldable USB AC adapter (.8A and 5V) to which I plugged in a Sync and Charge cable and it did just fine.
After reading all the comments about there being two ways to charge a Tilt - fast and slow, I decided to test out a retractable USB data cable with my USB AC brick. I set the option in Power to "Not charge the battery when connected to the PC." and plugged it in. Nothing. I then unticked the box and sure enough, it started to charge. As I was at 70% of the charge, I expected this to drag on, but it didn't. It took about 1 hour and was fully charged.
I'm still a bit worried about charging this way - the description of the Lil Sync cable for the Tilt says that while it might work, under certain circumstances it won't if your battery is below 30% of a charge. Has anyone seen this happen? The last thing I want is to go away for a few days and be stuck with a dead batttery.
Do I need to pick up a special cable from ppctechs or boxwave just to charge? Should I just carry the supplied charger?
I always charge my kaiser just using the sync cable and it works fine even from a flat battery. there seems to be absolutely no need to carry an AC adapter around when you can just connect it to a computer to charge.
Thanks Spooki. Just curious - how long does a charge usually take when you charge against a computer's USB?
it seems to take roughly twice as long as a wall charger but i work with PC's all day so doesn't really bother me, much easier than carrying a charger around.
I went out of town this week and made sure to grab my USB cable, but left the AC adapter at home figuring I'd just charge off my laptop via usb. Apparently not... I also tried plugging the USB cord into my iPhone AC/usb adapter with no luck. The only thing I've found is that when you turn off the Tab and connect to one of these devices, a green battery indicator will pop up showing that it is charging. Well, after about 16 hours, it made it from 15% all the way up to 48%. Does anyone know any way around turning it off to charge or why it is barely charging when it is off?

Well seeing as it has a 7000mAh battery, just about any run-of-the-mill USB charger isn't going to cut it. The amperage would have higher as well. Now i would hazard that an iPad charger (10 watts) would probably work just fine vs an iPod charger.
Your laptop's USB port isn't providing enough juice to charge fully. With the screen off it will only trickle charge and very slowly at that.
You'll need at least 5 Volt 2 Amp chargers.

I've ordered both last week but neither have arrived yet. I'll report back.
You need a 5vdc supply that will provide 2A. 10W, not 5w as the previous post said. That adapter on ebay won't help the charge, it just disconnects the data line so it does not change its mode when connected to a computer. There are a lot of power supplies that will work and even more that won't, just made sure it supplies 2a. If you want to charge off your laptop then you will want a Y adapter similar to what is on usb powered hard drives but even then you will need to use 2 usb 2.0 or 3.0 ports and will provably only get 1a out.

I know the Tab 10.1 says it's not charging when you connect it to PC but then so does the iPad 2.
Something I noticed with my friends' iPads is that they actually DO charge from USB even though it says they are not. Now, I thought to try that on my 10.1 and guess what?
Plugged it in at 67% and 15 minutes later it's 70% and still says not charging.
What's up with that?
It'll trickle charge if you don't use it, but it'll actually drain (or at best remain steady) if you use it while hooked into a USB port rather than mains power. That's not charging in Samsung's book. Same thing if you hook it up to a 1A USB wall or car charger.
Same thing with the iPad, the Galaxy Tab 7", and just about any other "big battery" tablet on the market.
Now, you can "trick" it into thinking it's charging with the use of a special cable, but it's not actually going to charge any faster on USB than it would without the cable.
The tab needs 2A to charge and if you plug it into anything other than 2A it will say it is not sufficient enough to charge. It will charge it, but it will take 10x as long to charge.
samething on the nook color
if you keep the screen off. It actually charges at an ok pace
Hello,
i've got a big problem...
I've bougt a used EEE Pad with Prime 1.7 and it doesn't charge.
I tried USB-PC, the original AC Adapter and one from artwizz.
The Pad has 13% power, wenn i put it off and plug it in it reboots like it's charging but it says: 13% remaining please plug in...
What should i do?
Thanks in advance!
Try leaving it charging for a while with screen off. If when you turn it on after several hours the battery has charged a little, then the charger is only delivering 5V and not the 15v needed for fast charging. The 15V is triggered by an gnd connection on pin 7 of the USB connector from the TF. Are you using any kind of USB extension? Std USB 2.0 extensions will not work. If all else fails get a Dynex DX-UA universal camera charger ( most electronics big box stores) and set output for 11-12 V.
I had the same issue couple of weeks ago (I posted here as well) and even got an RMA from Asus to send it in; but I didn't have to. In my case the battery was empty and when I plug in the adapter it would work but would not charge - the battery had an exclamation point on it and would not change to the "lightning bolt" indicating that it is charging. Since it works from adapter, that most likely means that adapter is ok. I also have a dock and when I plugged the adapter into the dock, the dock was charging so I knew that adapter is good. However, TF was not charging regardless if it was docked or not so I thought my battery died. The day before I sent it in for RMA I had it completely off and plugged in for a day or so. After that when I turned it on the battery showed full charge and it has been charging fine since then with no issues. So as Rumbleweed suggested below, as long as your adapter is good, turn your TF off completely and leave it plugged in overnight or longer. See what happens.
Good luck.
Will the Transformer show charging with 12V and 1500 Ampere?
At the moment it charges with a 5V 1 Ampere wenn its off.
The original adapter seems to be defect, but it works two days ago...
I've orderd a cheap 5V 2A to charge it over night. I found on amazon an adapter with 12V and 1,5 Ampere. Will it charge with it wenn i use it?
The original adapter costs 39€ and with a RMA i've to send the whole tab.
edit: An adapter with 12V and 1,5 Ampere should be working?
Mine has stopped charging today while the TF in on. It's only charging when the TF is off.
It will be soon three months I have it and it's the first time it does that.
When I touch the adapter, it's hot as it used to be before today.
I've tried to power it off and on many times.
hi all
i change my charger today ... same stuff, seems recurent problem.
I own a Galaxy S2. I have tried it using for navigation many times only to find that the battery discharges fully within 2 hours even if the phone is connected to a car charger. I used to think may be its because my car charger doesn't provide enough current to maintain the charge. But recently I found out the culprit. After around 20 minutes of use, the phone battery starts heating up, and it stops charging. I verified this with CPU-Z. It clearly shows battery overheated, power supply connected and not charging.
I was wondering if S4 also has similar issue. Has anybody used it for more than 2 hours with Google Navigation continuously while connected to car charger?

The most I have used it for is about an hour and half, and while the phone did heat up, it did continue to keep charging while connected to my in-car charger (just a cheap one). I can't remember whether the charger was able to keep up with the discharge though, I think it did. I was driving in bright sunlight, so I had screen brightness on max throughout that time.

I've found that the USB cable can have a big impact on the charging current. I had the same problem with my car charger not keeping the phone charged, even though I was using a 2A charger. When I changed the USB cable I managed to quadruple the charging current (from 300ma to 1200ma) and solved the problem (I measured the charging current using the Galaxy Charging Current Lite app).

In my case, I believe it was not because of the charging current or cable. I was trying with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. When the mobile stopped charging, I checked in CPU-Z app. The app was clearly showing status as "power supply connected, not charging and battery overheated". If I unplug the USB cable and connect it back, it will start charging again!
To make sure that I didn't miss anything, I will try with the app you suggested.
Just to update: The Galaxy Charging Current Lite doesn't seem to work with my Galaxy S2. It doesn't show any value.
