So I recently realized that I can't wirelessly charge my phone and use a flash drive at the same time. Is there a specific reason for this or is it just a oversight?
Maybe some technicality of current running to charge the phone may backflow through the USB port? If it was a wired charging, could you use the port for otg at the same time? Maybe a glitch to be solved in some future update? Who knows.

Hey all. Wondering if it's possible to charge the phone while using the following setup.
OTG cable into the phone. Powered USB hub into the OTG cable.
Can the phone even be charged while using OTG, since OTG is meant to power other devices?
I'm trying to find a decent setup to allow me to charge the phone, use a wired controller, and possibly an MHL. I could always just use a Bluetooth controller and the Media Link HD and charge the phone, but is it possible the other way?

Has anyone gotten OTG + charging working on the Turbo 1? Meaning, having a USB peripheral connected and the Turbo charging at the same time.
I'm using a USB DAC in the car connected directly to an amp. Sound is amazing. Would be cool to charge while playing music.
TIA.
I've tried to accomplish this on my Turbo 1 using hubs and splitters and whatnot. I am pretty certain that when an otg is plugged in the phone is incapable of receiving any current alongside the flash drive, since while using otg the micro usb port is in a sort of 'out' mode, so to speak. The only way I've found I was able to use otg+charging was to wireless charge. The phone gets a bit hot but that could be because I was otg-ing a straight up HDD; with a flash drive I'm not concerned it'll get too hot, and it definitely won't overheat. Let me know if you find other solutions
Hi all,
I was wondering if anyone knew of a USB Y cable (with two male usb plugs converging into one female usb port) that could allow quick charge and data transfer so it could be used with Android auto? Both male usb plugs would need to be able to transfer data into the female usb port in order for this to work.

I guess this wouldn't work and might also damage the head unit, but I'm no engineer.
If I were adventurous enough to risk frying my head unit and/or phone, I would follow this
http://www.instructables.com/id/Add...-hub/step3/Cut-the-VCC-wire-of-the-USB-cable/
and connect the output of the quick charge car adapter instead of the external charger.
Then would cut the Vcc wire directed to the head unit.
I don't know if the main hub cable (the one which normally goes to the PC) has to go to the phone or the head unit: who's the host in Android Auto? I'm inclined to think it's the head unit, since the phone connects in mtp mode. So my first guess is main hub cable to head unit, quick charge adapter connected like in the article, then big usb to micro usb cable to phone.
Maybe voltage higher than 5V would fry the hub, and maybe Android Auto connection is so picky (and it's picky, you know) that the hub circuitry wouldn't allow it. Who knows.
Again I'm no engineer and I'm scared to try
But I would buy a safe device tested for this use case, 10/10 :laugh:

Use a usb y, but don't short the data pins to send it to high charge/current mode. You won't necessarily hurt the hu but you'll never connect to AA, the phone must detect the shorted pins to enter high charge mode. Which means the phone can't talk on the data wires. I find a 2a charger running at 1a plus the hu's usb keeps just ahead of the power usage.

Unfortunately, you can't have quick charge (2.0) and data transfer at the same time (at least with my Galaxy note 4). On a standard USB cable, you have 4 wires, two for data, two for power. On my GN4, the data pair communicate with the quick charger (I'm not sure exactly what the communication is, I remember reading somewhere it used the data pairs to communicate voltage, etc...).
Now, what I did do, was make my own data cable using 2 male type A adapters and connecting it all up to a a male microUSB end(Data pair is only connected to 1 of the type A male ends, I can't remember if I wired up the power in parallel). My AA head unit puts out less amps than my car charger, so even though I'm not getting quick charge speeds, I'm getting a bit more amps to charge with. So, one male end goes to my charger, one end goes to my head unit. I've been using it like this for over a year with no issues.
How much better is it than charging while connected to the AA head unit? Not sure. I'd rather have more amps than not enough.
Just buy a y. Cheaper and safer than self making.

Do you have a link? Can't seem to find anything that I think would work.

Hi,
I want to clarify some aspects:
1) Qualcomm's Quick Charge doesn't work when the USB is in use for data.
2) Quick Charge requires a certified adapter (as it's an active function).
3) USB power can charge the device, however very slow... in fact with AA the device consumes battery when running.
So, my question is:
- Increasing the USB power current with an Y cable the device can be charged more quickly?
- And if this is true: the Y cable needs to block the current from the dta USB port of the car?
I like to comment these topics.
Whenever I connect my Phone to my Laptop(Matebook X Pro), it quick charges my phone. (connection via usb c to usb c)
Is there a way I can stop that from happening and my phone leeching the battery from laptop so fast? OR stop charging it all together
Because usually I only connect my phone to laptop for roms and rooting and today for Android Q. I would charge my phone before doing these things hence I don't need my phone to suck out from laptop during this. I wonder if there is a way to reduce how much power the laptop is outputting. or turn it off all together
Besides, I have a powerbank for both my laptop and phone so if I am out and about, I'd charge the phone from the battery, it's less efficient to send it from battery to laptop to phone.
You'll probably need a custom kernel with special settings for that, as they usually try to speedup the charging instead, but I recall some bugged kernel/ROM versions (for another device that was; the Nexus 6P) which prevented fast-charging when not using an official QC adapter (like connecting it to the charge USB-port of your laptop; and that kinda sounds like what you're after). Many modern laptops have special charger-ports, sometimes even with QC support, so did you try another USB-port to see if perhaps charges slower ?

You see, when I'm out and about I only carry usb c to USB c cable so I can't check other ports. Both of the USB C ports are USB PD :/

Use a cheap legacy micro usb cable plus type c adapter. Since its hard to find bad quality usb c cable. It wont pass high current to your phone. Bad quality cable usually have very thin wire..
Does anyone know of a USB cable that it capable of supporting AA and has USB-C on one end (for device) and double 3.1 on the other end (to vehicle)?
I have 2 USB ports in my vehicle. The input port for AA does not charge the phone sufficiently when is running and the other port does fast charging but doesn't allow AA to run.
Thanks very much!
Welcome to the never ending problem! No, it is not possible to do what you want to do, that is, to be connected to AA and to fast charge your phone from an other usb port or car charger. I tried everything, including powered usb hubs, nothing works, unfortunately.

Do you have wireless charging on the phone? Might be able to add a wireless pad in the car.

Thought about that but I'm worried about overheating. I guess I might need to try it and find out?
Do not be worried of overheating, if the phone is connected to a usb cable and port and it detects charging, it will automatically disable the wireless charging.
The only way is to replace, if possible, car's charging circuit with a fast charging one.
