It's said in the title. Anybody know how to do that ???
don't know a way to do that cause usb is delivering power and kf will take it to charge ...

there should be a way, at least you can cut the power wire

That would be the only way, modify the usb cable to not have the power line.... Non~changing cable.
isn't that stuff mandated in build.prop or one of the items in system? find that edit it to usb mount off or something.

Hello.I was wondering if i can power a high mcd led from the usb connector on the blackstone.It would give more light for night shooting.Anyone that has some info on the connector specifications?
i need something like this too... but will the phone recognise it??

It doesn't need to recognize it just to power it.
erhm, I think that won't be possible....
the usb port is used to charge the phone, IE. to receive power.
I don't think you can draw power from that port, the data lines are certainly not made for it, and the powerlines won't output anything I think
I am sorry if this already exists.
When I installed CM10 Nightly 02-Oct I noticed that when charging (both wall charger and USB cable) the phone does not show that is charges.. but it does.. and normally, 2-3 hours is full.
Also, there is no way to get the PC to find phone. When I connect it via USB cable it does not do anything.. only quietly charging.
Download mode and ODIN.. I tried... nothing.
Is there a problem with the port? But then how come and it charges?
So so weird!!
Thank you in advance

try changing USB cable or a solution from My Android Solutions

Thank you for the reply.
I tried everything.
Different laptop.
Different cable.
Different charger.
USB drivers(Google drivers and reinstalled samsung drivers and tried KIES)
The phone does not react when I plug in the charger or cable. Only quietly charges.
Even in Odin and Download mode it is not recognised(even the sound that a PC makes when you put something in USB is not there). What is wrong?
At least thank God it is charging.

Its possible one of pins could be damaged in the Micro USB, externally or internally , try cleaning like here or this
I bought a Nexus One with the infamous broken power button issue, and I am curious what would the effect be if I short the VCC and GND line in the charging port? Has anyone tried that? I am thinking that it will either fry the board or trick the phone to think that it is charging.
The reason I want to do this is because I travel a lot and I might not have access to USB charging if I want to swap the SIM card. I am familiar with the other tricks regarding remapping the trackball_center and I am going to install a version of CWM that doesn't support charging (that way the phone boots when I plug a charging cable).
So long story short... what do you think about attempting to short the micro USB charging/data port?

Not much.
Unless the unit is in USB host mode there will be no voltage on the Vcc line.
Even in USB host mode it should be current limited and do no damage.
Still, I wouldn't do it.
I don't know why you think that shorting it will do something useful.

I actually do not know, thus I asked... just trying to think outside the box about a way to trick the phone to think it is charging short of carrying a portable battery charger with me (which can be problematic on carry-on luggage).
Another idea I am thinking about is building a small flex cable using a conductive ink pen that permanently connect to the phone's battery on one side and a cut down male micro-usb on the other side (to slim it down). Such cable would be small enough to fold under the battery cover and allow it to close.
My question is: Will the ~3.7v be enough to get the phone to start charging? and do you foresee any issues with feeding power from the battery right back into the phone's charge port?

I think 3.7 won't be enough. Coz usb giving ~5V. So phone won't charge at smaller voltage.
I got in a really nice and sleek Impression I10A Tablet.
The Connector for the USB/Power has broke and, unfortunately, it's the only connector available for power..
http://sjfm.us/temp/i10aConnector.jpg
Now, my first thought was to replace the motherboard. No such luck. Finding ANY kind of Impression parts is difficult... Second choice was to replace the power connector itself. Tedious and a pain in the arse, but doable. But I have had bad luck IDing power connectors for tablets (most notably Kindle Fires and the MicroUSB) so if anyone can help identify the above connector...

Anyways, so then I got creative and, just to confirm "Proof Of Life" (so to speak), I hooked up a 12v 2a power adapter directly to the battery connector (Red Box) to bypass the damaged power port (Blue Box).....
http://sjfm.us/temp/i10aPower.jpg
.....on the PCB and viola'..
We have a heartbeat!!
OK.. So now I am thinking that, if I am lucky, the 12v power will power that tablet AND charge the battery.. But then I am thinking that there is likely more to charging a battery than simply applying a power adapter directly to a battery and getting a charge..
Sure enough... When the battery AND the 12v power is hooked up, the tablet boots up under the battery and then dies before it can get to the dashboard..
When the 12v power alone is hooked in, the tablet boots up fine and shows a full "charge"..
So, here's my question..
Is there a way to kludge a power connector to bypass the damaged port and power the tablet and charge the battery..
In the alternative, can anyone point me to a knowledgeable source that might be able to ID that type of power connector??
Thanx in advance..

Never connect a power supply directly to a battery.
That's a recipe for fire and explosion.
12V? Why do you think that anything is 12V?
Does the stock AC adapter say that?
If you want to get this thing working properly you'll have to figure out on the circuit board where the AC adapter hooked in.
If you are sure of what the total battery voltage is (how many cells) then you could also hook a power supply in with the battery disconnected.
Thanx for the reply. Apologies for the delay in responding. Was out of the country for a week... In the middle of the Atlantic Ocean. No web access!!!

Yea, as I soon found out. I was tinkering with it longer than normal and a small little component near the power connector released the blue smoke.. So, I think that MB is borked..

Yea, the stock power adapter for the unit is a 12v/1.5A power pack.

I do plan on repairing that component. Eventually. Once I do, I'll put your advice into practice..

Hi all, I own a Note 3, got the idea from the following link:
http://www.oneclickroot.com/how-to/how-to-quickly-charge-your-androids-battery/#readsoruce_bottom
Here's a quote from the page:
DOUBLE USB CORDS
I use a mechanical keyboard that has two USB ports. Why? The keyboard – for whatever reason – requires more power than is provided by a traditional USB port. It plugs into two USB ports simultaneously and provides additional power. Some third-party micro USB cables also feature two USB ports, in which case you can access twice the charging power from your PC

Has anyone tried that out? Using double usb cords?
Thanks

I can't see it working if you are using USB 3 port as that pumps out 2A. Maybe if you were using USB 2's it could crank up the amps and make it work.

I'd rather have it charge <500mAh to prolong battery life.
And i wouldnt use/recommend those 2USB connector cables. As it may short out you computers USB busses.
And its also very likely that with those cables (with the 2 connectors on 1 side) have just one of them connectors for power and the other just for data. So you can put the extra plug into a wallcharger.
Dont try to fast-charge lithium battery's they still dont really like it. It shortens life drasticly.
Just keep it charging overnight when asleep, the comment about having lithium battery's at 100% and being bad for the battery is not valid anymore. That was only for the 1st two generations.
Now with these 6th or 7th generation lithium battery's its not a problem.
