HI,
does the i9000 Galaxy S support the quick/fast charge from battery charging spec. 1.1?
My new pc mainboard does support this via software/driver. And allows to load with up to 1,5A
I couldn't find information on that.
The i9000 is USB 2.0 not USB 3.0, so the answer is no.
not exactly correct
as it does charge faster with a higher AMP output charger.
i use a 2 Ah or 2000 mAh charger in my car and the phone does accept the faster / quick charge
so if your PC has the option to do the higher 1.5 Ah output, it will take it just fine
just like if you have a 1200 mAh wall charger as some people here uses.
I installed the asus driver which installs a service and the aicharger.sys
I restarted.
They tray shows an icon with a plug, but it is crossed. Like disconnected.
I pluged in the i9000 via the usb2.0 port an no changes.
I then pluged the phone in to a usb3.0 port but the icon still shows disconnected (or ai-charging off)
Any ideas?

This is the bit that is not exactly correct. Regardless of how the hardware is set up it's up to the phone driver to request a powersupply from the computer. As it is the Galaxy only requests only 2 unit loads (200mA) from the computer, no where near the 500mA max of the USB2.0
So no simply plugging in a more capable computer won't change a thing.
interesting.
Are there any mods or fixes to support more usb power while connected to a pc?
None that I have seen.
ok, so the only possibility to charge faster is, to get an after market 3rd party wall plug with higher current than 700ma?

Interesting. So does the SGS actually use all of the 700mA out of the stock factory charger? If I use my 2.1 A charger could I overheat the battery?
Ok I've had it with the speculation. I've got a USB micro socket and plug on order and I'm going to make a pass through cable and measure the 4 different chargers I have here at the moment this weekend so we can put this one to rest
Stay Tunes.
Ok did a test. No the SGS does not use all 700mA. It uses 470mA. Charging is faster from the dedicated charger than the computer. I verified that the phone only draws less than 100mA from the computer socket.

Thank you.
But can I get more current from my PC with ASUS ai Charge?
I installed the driver but the icon in the tray doesn't recognize my Samsung.
That is because it doesn't have something an Apple Product has.
Apple products get more current with that driver/software thing. But the i9000 doesn't work with it.
in the past i checked if it is possible to charge the battery faster, and not Necessarily through the phone.
i asked a guy who works with electronics and he simply explained that everything is possible, even charging the battery to full in a few minutes, but it WILL kill the battery very fast...
yeah i installed to anticipate a quick charge...but all i get is icon with a big cross...
deleting it now......its useless to me...

Everything is possible when you charge the battery itself directly, but not when you charge through the phone. The phone is the charger. The computer and the wall plug only provide power to the phone. Unless you go in with a soldering iron there's nothing you can do to speed up the charge beyond what the Samsung wall adapter gives you.
My laptop recognizes my GT-P6210, and has even before downloading Kies but it won't charge the device.
I downloaded the Kies drivers here: http://www.samsung.com/us/support/owners/product/GT-P6210MAYXAR#content2
It appears that the above is the only drivers...that I could find at least. Does anyone know what the problem could be? Does the laptop just not charge the device?
Thanks
Computers cannot charge the G tab, unless you have a charging cable or an adapter. They can be obtained from eBay.

i think it might charge, just really slowly
No it definitely does not charge, since a little red X appears on the battery when I connect it.
Thank you both!

wrong.. it charges but super slow.
try esata/usb port
On my laptop it does charge very slowly. For best results lock the screen and use the esata/usb combo port if you've got one. Seems to produce more power
It's normal that a PC or a Notebook can't charge a tab unless u have special usb-port that has a higher output.

I have higher output USB ports but it's still just a trickle charge on the tablet. My cell phone charges fast using the same ports.
Usually cell phones have 1000-2000 mAh. The Samsung Galaxy tab 7.0 plus is 4000 mAh. It charges, but a a very, very low pace. The greater the battery, the longer it takes. And on top of that, the system is always draining the battery, even when the screen is off, and with more demanding processors, the greater the consumption. Just think of the new Ipad, there are already reviews that advise that charging it through usb port is not practical at all. Please, I'm not starting a flame here, just pointing out that fact. In fact, very likely the Android tablet will follow the same path, given that the future is quad-core and even more cores. May be this will be solved with usb 3 that promises greater voltage (or amps, I'm not sure).
I use USB 3.0 ports for charging, tablet is a trickle charge, phone charges fast.
actually it is charging, the x symbol/logo just to remind you that charging using usb is not effective and very slow.
Yeah. Mine too. It shows a Red "X" till I read somewhere in XDA forums (can't recall where exactly) that we can get a special cable to do the charge.

When I plug in my Infinity to start transferring stuff from my computer...it doesn't charge. I don't remember if I read if it worked or not? Anyone want to confirm? I know someone said something about the dock not being able to charge, but the tablet should.

I don't think the USB on a computer is powerful enough. My old iPad couldn't charge from a computer either.
Sent from my 3d porn machine.
Someone in the TF300 section mentioned that theirs would only charge from USB if it were completely off, and even then it charged pretty slowly. I wouldn't be surprised if the 700 were the same.
Mine charges when I hook it up on the USB port of an Ubuntu machine. But very slowly since the current is low.
I've heard a lot of different tablets don't charge via USB. That sucks...it just drains away battery while sitting there copying, slowly might I add, via MTP. I'm charging it now...I'll let it sit and transfer some more after a full charge.
Same, no charging from laptop.
I'll live though

Well unfortunately the only way to move large files to my tablet is via MTP and if my battery is getting low then I'm screwed lol.

Yea, I had about 24% battery when I rooted and it was worrying me to since it wasn't charging at the same time. Then I realized that 24% on a tablet is a lot more than 24% on a phone. Whew!
I hope it was not a dream but i plugged my tablet on my laptop and, while it was in halt mode (thus not power off per say), it charged itself up to 100%. So basically, my answer would be that it does charge itself on a computer, but it is far from being enough to cover both the use of a tablet and the charging process. And btw, since mtp is awful-as-hell slow, shouldn't we use like ftp servers or through-ssh transfers ?

There are a couple of mentions in the manual regarding the USB charging.
The first one being "Ensure that your ASUS Transformer Pad is turned off before charging it via your computer's USB port."
And the second, "The ASUS Transformer Pad cannot be charged via the USB Dock cable when it is connected to the mobile dock."
So, I guess it proves that USB current is just not enough to sustain tablet's use and charge the battery at the same time.

I know what you meant, but can't help noticing it should be about the speed of light anyway...
Some of the newer tablets are using usb3 charging plugs for the wall outlets. If you know some or have a usb3 port on a computer, you could try that and see if it charges faster than the us2 ports. The t300/prime/t700 all use usb3 plugs.
I transfer stuff by the micro sd card, adapter, and my computers card reader. It's not as convenient as plug and go but I'm usually transferring video files to watch at work and they are large.

I thought that MTP was already bad, but adding the slow I/O on top of it is painful. What's the best way to transfer stuff?

You hit the nail on the head. I think I saw someone here mention theirs would wall charge if they had used a usb extension with the wall charger - and it turned out that the extension was only usb 2 which prevented charging.
I posted a thread about this in the Q&A section.
Basically, from my own experiments and some other people's observations in that thread:-
If you are using the tablet while it is plugged into a USB port, the power will drain very slowly or maintain the same level.
If you plug it into a USB port and walk away, it will power up.
I left it plugged into a high power USB 3 port at 78% and left it for about 4 hours, when I returned it was at 97%. and it continued to read as "Not charging"
For some reason, when the tablet is plugged into a USB port, the battery info says that it's "Not charging" but it is.

-------------------
There is a small trickle effect of power which is why the manual says to have the tablet off. That trickle effect is what you are seeing. It could be a computer doesn't supply enough power to its usb ports regardless if it's usb2 or usb3. The wall adapter could be pulling more power in it's design. If you search amazon you can find non Asus data cables. I've used one on my prime after my cat chewed the original. I think it is like 6 bucks for the cable. I don't know there is an off brand product for the actual wall plug. But it's something to look into if your interested in having more than one recharging locations.
I'm not so sure that makes sense to me. 30% increase in power in 4 hours, seems like more than a small trickle effect of power, and doesn't the infinity manual says you can charge via USB.

USB is 5 volts. Asus Transformer uses like a 12 Volt Charger. On my TF300T, the pad would actually still lose battery life if I put it on performance mode (rooted 1.6 ghz overclock). On balanced it would depend on what I was doing. I imagine the TF700 is the same. On the plus side, because the charger is 12 volts, it also charges the battery a lot faster. Plugging in my ipad 2 into my iphone charger seemed to recharge so slowly.
I dont know about the tf700, but I downloaded the Asus Ai charger and i can charge the ipad2/3 and the ipad shows that its charging. It a different case when I tried plugging in the Asus transformer prime... nothing.. Its wierd and Asus charging program lets the ipad charge but not the prime.

This!
As much as I love this machine, its software is terrible.
When I connect the cable for my N8005.1, it immidiately goes for storage as external device. At this moment, there's a "X" sign on the battery icon; the device is not charged via the cable. When you click the icon on the bottom right for more storage options, there's only two options; one "as MTP device" and second as "camera" (BTW, the detailed storage options doesn't exist on settings menu)
What's to be done to maintain only cable charge and not do any storage? What do I miss?
Thanks

Note 10.1 needs a 2Amp usb charger to charge battery .. the usual PC-USB port does just 0,5Amp => your Note will not charge at a PC ... or any charger with less than 2Amp

Hmm, so the battery will drain when you connect the device as 'ext drive' and BT audio at the same time. This means we'll have to carry chargers around :-|
Thanks.

Should be true, but doesn't.
Note will show de red X in Battery, but will charge. Very very very Slow, but will charge.
I did the test.
I connected note10.1 on usb 2.0 at 9:24 with 83% of battery. At 10:26 has now 88% of battery.
So, Will charge very slow. 5% per hour in my case.

As soon the red X is showing charging cant be guaranteed .. if you are using lot of apps od Wifi/3G the battery will drain .. if the note is more or less in standby mode .. it may charge!!
The operation with the red X is not recommended as this is not a stable mode for the battery (swapping between charging and draining!!) and may reduce the lifetime of your battery!
yes .. you may have to carry the charger all time with u
This is one of the annoying things with this tablet, is you always have to charge it using the wall charger. I always thought the X mean that it wasn't charging, will try to connect it my laptop and see what happens.
Is there a way to charge the note 10.1 while using the usb connector? I would like to use a usb flash drive and charging the same time.

I don't think that is possible, still you can try a usb multiplier with separate power and see . I know that it can support multiple usb flash drivers connected same time but i'm not sure if it will charge
And be careful, you could end up frying your tab... I was using a powered HDD and something went wrong. Long story short, Dead tab and dead HDD...:crying:
So I went out and got the 32gb 3G version...
i connect my tablet yesterday to my PC and left it 32% then i slept after like 8 hours sleeping i waked up and find that my tablet 100%
The tablet will trickle charge when connected to usb. It's mainly that it takes a whole heap longer to charge...
