I bought the SlingPlayer app as a way to listen to news at work while I do my work. What I have noticed is that plugging it into my USB port slows down the battery drain of the app, but the power draw caused by the app is more than the USB port can provide, so after enough time, I have to shut down SlingPlayer to let the battery recharge.
Are there any settings that I can do (under clock?) to reduce the power draw?
Would finding a two male USB to micro USB cable from somewhere(?) do the trick, or is that dangerous doubling the amperage?
I am hoping there is an option that does not involve a power adapter, because all the plugs are already taken.
Usually computer usb ports are only 500mA. The wall charger that came with the phone is 700mA and the phone itself it's 1000mA.
So the phone is using 1000mA while you're providing it only 1/2 of the power it needs.
I would recommend getting a usb wall charger that supplies 1000mA or if you can find the Y usb cable for your computer that would work too.
Reduce brightness by 50% see if that helps , screen is biggest power consumer on cell phones. Or just power it from wall charger not computer USB port.
I have just bought up my transformer ( Love it ) but it's at about 10% battery right now... I take the cable that came with it (the usb one) and plugged it into my computer but it is not charging ? Any idea what's wrong with it ? when i plug it into the charging unit it works fine though
i've heard it has to be turned off for the USB charging to work....
Like off as in screen off or off as in complete off ?
It will not charge in your computer. You have to charge it in the wall.
Sent from my Desire HD using XDA Premium App
One of the pamphlets that came with it said the screen has to be off in order to charge it using a computer's USB port, cause the screen uses too much power and a USB port doesn't output as much, its best just to charge with the ac adapter. Nothing is wrong with your unit, thats just how it works.

Turn off the screen and it will charge. (you don't need to turn it off; you just need a black screen) It is very, very slow though.
My wall charger never charged my tablet so I am awaiting a replacement. The USB charge is MUCH slower than the wall charge. We are talking about maybe 4-5% an hour -- max with the USB cable alone.
Connecting this thing to a computer will NOT charge it. Even a normal 5V 1.2A-2A charger won't charge it fast enough. I used a 2A charger and it trickle-charged for over half a day and managed to clock in @ 50pc. I think the unit uses hardware info from the ASUS charger to detect the charger. Any other charger wont do.
Isn't the cable and charger USB 3 and charging is at non USB 2 values (voltage and current).
Good amount of mis-info in this thread...
The unit *will* charge from computer USB, assuming the USB port provides enough amperage (not voltage). I have not yet measured out the amps used, but it's on my list of things to do...
In order to charge from computer USB, the display on the Transformer needs to be off. The unit can be on, but it must be asleep.
The adapter that comes with the transformer provides 15VDC via extra pins which loosely resemble USB 3.0. These are *not* USB 3.0 data/power specs, however a USB 3.0 extension cord could be used to lengthen the existing adapter.
Any USB car adapter should work to charge this in sleep mode, similar to a computer USB port. In order to "fast charge" in a car, however, you'd basically need to use an AC inverter with an ASUS Transformer adapter.

Tried a 2.1A 5V charger. Took about 8 hours to charge @ 50pc. The ASUS charger is rated at 1.2A.
is the only way to plug the device into your PC or laptop via USB on the dock?
you cant use the proprietary charger cable to do USB data transfer with the charging cable USB component?
ie....to do data transfers via USB (not the memory card), the only way is via the dock?

No, one end of the charging cable is regular USB and the other end (tablet-end) is proprietary. You can transfer files over by connecting to your computer's USB.
awesome, thanks.
do you think that if you get a male/female USB converter, you could plug in a USB memory stick device or a mini hard drive device and have it work fine in the charging cable just like you would if you were to plug in a mini hard drive into one of the usb ports on the dock?
I made an video/audio out cable with power connections. I bridged the USB data connections (white & green) so the phone allows full AC charge current.
However, when I connect the charger while outputting audio/video, it does not charge. Tbattery app shows that it is recognizing the charger type as AC, and the LED "breather" light on the hardware buttons indicates it's charging.
When I do not use the A/V output cable, I get about +200mA charge current USB, and when I plug it in regular AC charger, I get about +700mA charge current.
But when using my custom cable, I am getting about 100mA charge current, but the phone discharges faster when its connected.
Can anyone help me with this? I would really appreciate the help!
Is it possible to obtain a USB cable for fast charging, i.e. more than 500mAh without modding?
See for example:
S107 S105 USB Charger Charging Cable For Mini RC Helicopter Syma S105/S107 2A
I'm asking because a lot of USB chargers in the range of 1000-2000mAh come with either no USB cable or a standard USB data cable that limits charging to 500mAh.
Hello,
if I use the USB Power adapter and the USB cable from Google, I get a charging speed of about 6-7 % per 10 minutes.
When I use USB Power adapter from google and the USB cable from my kindle, the charging speed is half.
How can this be ?
