When I connect my Honor 10 to anything it makes the device connected sound once.
In my car, it makes it over and over again and I can't find a way to switch it off.
The USB power adapter can supply 2.1A or 3.1A and it charges really quick as expected but the device connected sound on repeat is really annoying.
Any suggestions?

I purchased a new vent holder with a car charger, and it charges the phone up OK when it is off, but if it is on it says charging but does not actually charge. This is especially annoying with Satnav and after an hour or two the phone dies and I don't know where I am going!
Anyone know what causes this? I guess it can't provide enough power for the device, especially when using the internal GPS, but I think it doesn't even keep up with the device is just turned on.
I am getting another charger just in case, but never had the problem on my old Touch....
..
try -> start/settings/system tab/power/battery tab - uncheck the box "when the device is turned on...."
It isn't ticked...
..
try ticking it..
That will have the opposite effect, it charges fine when plugged into the wall, the problem is something to do with the car.
Does anyone use satnav on a touch HD and have it charge at the same time?
Well there could be one or two issues.
On the USB port there are four connections, a positive and a negative and two data pins. When you plug your Touch HD into a PC power is supplied down the power pins and after negotiating with the USB controller chip over the two data pins the phone will pull up-to 500mA from the power supply to run and charge the phone. This is so the USB port on the PC is not damaged by the phone overloading the power supply to the port.
Without the negotiation with the USB controller chip the device will only charge at 100mA.
But 500mA is not enough to charge the phone with everything running, you will need at least 1000mA to do that (1 Ampere). So that is what your wall charger pushes out. But how does the phone know it can charge at a higher rate? Well inside the charger the data pins on the USB connector are wired in a way that the phone 'sees' that a higher current is available, and pulls a higher charging current.
So what you need is a minimum current 1 Amp car charger. If you already have a 1 Amp then the chances are that is does not have the data pins connected properly and the phone will not draw the higher current, meaning it will only charge at 100mA.
Thanks, I am going to try another one and see if that helps, perhaps it is just faulty, otherwise I will check if it is 1Amp.
Cheers.
I contacted the seller and they sent me a new one, which works. So it turns it my charger was just faulty.
What's the rating of the new one? and where did you get it from. I bought a 2amp (supposedly) but it doesn't give me more than 500mA.
I've had this problem and it sucks! As I'm always out on the road. But I have found a few solutions. I purchased a mini usb charger from asda for £6. After adjusting the backlight to medium this charger seems to keep the power level the same as it was before you plugged it in, so It doesn't let the battery go flat. I've now learnt to keep a spare charged battery in the car just in case it fails.
Hi,
In my 2 different make vehicles if I plug the HD2 into the Aux Input of the stereo and then into the car charger the phone instantly restarts (in one of the vehicles) or gets an instant red, blue, green, white screen which takes a couple of battery removals and restarts to cure in the other vehicle.
Does anybody have any idea why this happens?
All is fine if I only plug into the Aux Input but any attempt to charge the phone as well kills it instantly?
Tried a genuine car charger and a cheap Chinese knock off, both do the same thing.
Appreciate any suggestions as to why this may be so, would a diode in the charger line help?
Thanks.
Wow thats kinda wild. The only thing I would say is never start the vehicle with the phone plugged in. Most Chargers are supposed to regulate the volt/amps but if the charger is messed up even a little it could fry your phone. On a side note I had a car EQ in a PC one time and if you cut the EQ on while the PC was on it would restart the PC. So we always cut the EQ on First. With that said perhaps your problem is the order of operations.
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.
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?
When I connect my LG L90 D410 phone with Android 5.0.1 to charging with the travel power adapter (output: 5.0V) that came with the phone, it charges fine most of the time, sometimes it heats up the phone. Also when I connect the phone to my car charger, the phone heats up quickly every time.
However, the heating does not happen when it is connected to my laptop high or low powered USB 2.0 ports.
So, I want to check the power output of the chargers that I use with my phone.
Please suggest if there is any app that can measure the power input the phone is getting from the charger that is connected to it.
Try out Ampere in the play store.
