How does the smart dock behave when only the charging cable is connected? Does it still displays tv-like UI preventing display to shut down or does it know whether the hdmi is connected or not? I plan to use it only as a charging stand.

I believe that there is an issue with charging performance in the Atrix car dock. I'm using the OEM Motorola ECOMOTO Rapid Rate vehicle power adapter (850 mAH) with dual USB ports. You can tell this USB charger is a good product just by the weight of the thing! A test charge in the Atrix car dock began at 7:45 AM and the phone's charge was 20%. At 9 AM 30% and 10:30 AM 40%. This is obviously nothing like the wall charger so it made me believe that the phone was powered by the charger while docked but only receiving a trickle charge. Connecting the phone directly to the USB car charger (without the car dock) using a stock USB to micro USB charging cable, at 8:00 AM the phone was at 20%, 8:20 AM 40%, 9:00 AM 70% and 10:00 AM 100%. What a contrast!! So it appears that there is an issue with charging performance while in the car dock. I've reported this to Motorola and hope that they can reproduce and address. How about the rest of you, what say you all?
Mine charges fine. I have the moto - 2usb port charger and it powers the phone in the dock just fine (mine is Y shaped and ships with the MotoBranded car dock, not AT&T).
Mine charges just like the wall charger - both put out 850mA. If I am running Nav in the car dock, and screen is on, it charges slower - but this is to be expected.

I find when driving around during the day with the screen always on, taking the occasional call and GPS/Navigation running most of the time (not sure, just love seeing my KM/H sitting up there helps keep my heavy right foot off the go pedal) that my battery slowly slinks up in % almost like it's not charging due to the load I have on it.
old thread but..
Hello
I know its old thread and no one is interested anymore but I found out that Atrix is giving power back to the vehicle when connected to the car dock.
I have a Cigar lighter slot hub with an LED indicator. The LED remains glowing when I turn off my car and leave Atrix in the Car Dock. I found out that ACC are having power until Atrix battery is empty.
Even if I unplug the HUB from the car, LED remains glowing, but battery drain seems not that high than connected to the car.
Once I remove the Atrix and put it back, LED is not glowing again, so I think it has something to do with the Car Dock and the Atrix software. (not sure)
I'm trying to make a work around with relay...
When I plug into the wall or use a power inverter in my car, it says "charging AC" and charges quicker. Although if I use a car USB dongle charger, it goes into "charging USB" mode and unfortunately, charges much slower. This really ticks me off as I just picked up a rapid charging 2.1amp(2100mA) USB car dongle.
Is there a way to tell the phone to charge as AC instead of USB? Or at least an app/widget that will change it?

max current in the USB spec is between 500 and 900 mA depending on version. Congrats, you got scammed. Take it back.
Edit: Correction, there has been a modification to the spec to allow, ostensibly, mobile devices to draw greater power when charging. The device may draw up to 1800mA when connected as a Dedicated Charging Port which disallows data transfer in this mode. Two things to note about this. First, the HTC supplied AC-to-USB adapter lists a 1000mA (1A) current output, and your users manual (you did read the manual, right?) specifies you should only use this charger with your phone. Second, despite the fact that I am not even sure you would want the phone to take 1800mA, when it's designed to charge with 1000mA, your "rapid charging" device is STILL over-specced by ~14%. Not a gamble I personally would be willing to take.
Good luck.
Edit 2: To answer your original question, no, you cannot fix this in software. The dedicated charging mode is triggered by shorting the d+ and d- data contacts. If your USB dongle doesn't do this, then the phone will never, ever be able to recognize it as a dedicated charging port and you will only get 900mA charging current at 5V per the standard USB spec.

Yeah, this seemed to be the final answer for giving the Desire enough juice to charge in a car while running nav. I don't plan on using nav a lot in my daily routine, but it would be nice to have a safe, effective answer to getting an "AC Charge" in a car. I saw the picture of voxigen's 12v port -> inverter -> AC USB adapter setup, but I don't have that much room around my 12v port in my car lol.

i wouldn't mind continuing to use that inverter(aside from occasionally hitting my knee on it), just the downside to it is that whenever i'm playing music from my phone -> stereo, there'll be this weird buzzing/hissing sound in between tracks/when a song is paused, but while a song is playing it goes away... and it does not do that when i plug in through that usb charging dongle.
I've set up my Z2 as a Sat Nav in my car and using a magnetic USB lead plugged into a 3A charger. I've noticed that the phone doesn't really charge with Google maps running and playing music. It slowly loses the charge. Has anyone come across this?
Have the same issue with mine. I've got a magnetic adapter that I use with my ordinary USB cable and it can't charge the battery when I use waze and Spotify. At night I use a magnetic charger cable and then it's charging fast but not with my adapter.

Mine also charges very slowly or even discharges depending on the usage through magnetic port. My guess its due to cable being ****ty
I'm wondering maybe the cable is not delivering enough current despite my charger can output 3A.

i think this might be a Problem of the magnetic Ports!
Pretty sure screen on, gps and active sat navigation type app on nearly all android phones will lead to this.
Fact is the device is using lots of power, so much that the charger can't keep up. You also will likely find the phone will struggle with heat issues while doing this.
Running into a problem... While charging the Tab2 from the wall outlet, it is fine, works great. While trying to charge from a USB cable and my car, it says it is charging but there is a RED X on the battery... Research says this is from a charger with insufficient amperage to charge the tablet. Since this is going in a car as an in-dash install, I will not be able to access the power button. What I need is this: A way to make the USB port in my car more powerful... I want to use this because a key turning on powers the port which in turn wakes the tablet up, then the dev option for 'STAY AWAKE WHILE CHARGING' would apply and the tab would stay on... now, this works however with that Red X, the tablet charges but not enough to make the tablet stay awake... Any work around on this? I can not find much out there on this. Even if I have to tie a new 3A USB female plug in down there, that's fine... but what I need to know is, the factory OEM Samsung car charger claims to charge the tablet fine and it is only 2 Amps... I have a 2.4A charger and it does not work.
Or... is there maybe a setting someplace that I can make the tablet not go into a data mode when plugged in so it forces a charge or something? Or a way to modify the USB port itself to charge instead of data... thinking maybe the port is telling the tablet it is a data mode and not charge mode...
have you tried a power inverter plugged into the cigarette lighter (or hard-wired)? Or a more powerful USB Car charger?
Has anyone else found that if you plug in the charger when connected to the Samsung keyboard the tablet will only slow charge? Even when the advanced battery setting is set to fast cable charging, my tablet changes automatically to slow charging when connected to the keyboard. If you disconnect the tablet from the keyboard, plug in the charger, and then connect it to the keyboard it will fast charge. Anyone experience this?
