yeah I believe. in my case even when my RT is sleeping it still provides change to any USB that I connect

Yes.

I tried charging my mobile phone with the Surface USB port and it doesn't want to.

When I try on a laptop it works fine.

So, what I am thinking is that the Surface is not supplying enough current to the mobile phone while the laptop does.

Or could it be some other reason?

It takes a while. For me it takes like 5 seconds before it starts it charges my phone

Works for me, I normally charge my phone from my Surface when using my phone as a hotspot. I've noticed a couple of times that if I plug the phone in while the Surface is off and it doesn't start charging, just turn the Surface on for a second and it gets going.

I believe only e-sata ports will do that, and I don't think we have one of those.

E Sata._. ? Um the surface rt , surface 2 or the pro and the pro 2 don't have sata ports. That said I believe that the motherboard have to support charge when sleeping and I know the surface 2 does charge when its sleeping . Though I'm not sure once it's off

I tested this today. My Samsung Focus (new, my fourth) was down to 10 percent and, after turning off and on, I connected it in to the USB port of a sleeping, unplugged RT. I got the usual chime on the phone and the charging symbol on the phone, -but, not the animated or toggling symbol. Next, I woke up the RT, and connected the phone again: same result, except that the RT also chimed upon connection. Finally, I plugged the RT into a power outlet and then connected the phone: same result. In each stage, I waited at least a few minutes and saw no change on the phone except that the "charging" symbol would disappear after a moment. By the end of the trial, my battery was down to 4 percent. So, unless there's a phone or RT setting I don't know about that is interfering, my USB port did not charge my phone.

For a follow-up check, I charged the phone to 40 percent to see if a less-drained battery would charge; alas, no differences. I have no need for USB charging, but I do like experiments. Best battery life to all. :smile:

Hmm could be a setting thing because on my rt it charges my phone fine even when my surface rt is unplugged and sleeping as you can see my rt was not connected and my 810 was charging
