usb power tether

Greetings! I tether my celly for use as a modem but it uses battery power. I want it to use the PC power thus not draining the battery thus happy celly thus happy me Any thoughts??

You talking about Wifi tether? Because what I do is I USB tether and no power issues.

If I understand you correctly and Ive not tried it but can you not connect the phone via USB and and then wifi "tether" simultaneously?

Remember the thread about IntShrUI ? Just run this file located on the windows folder while synced and done!

"I think" I now understand the issue...
I got curious and tether my Phone over USB for a few hours while downloading a big file, the phone eventually died, apparently it uses more power during tether than the PC USB can charge "500ma". The only thing that comes to mind is that you could use a double USB cable that would provide 1000ma or wait for USB 3.0 cable and hardware which provide such already by default. Or a AC to 5v powered USB cable? That's all that comes to mind, unless you can hardware hack a PC's USB port to provide more power lol

Makes sense to me since a recharge via the wall plug or my car (vs. a USB port on my PC) is much faster.

tethering
I use the assasins lament WiFi router while using the AC usb adapter. I understand exactly what your are referring to. I have tried to use the dual usb cable that comes with the Imagio, one side for connection and the other for power, didn't work to well.
One major concern is while using the USB tether mode the active sync needs to be disabled, thats a bugger when you want to download and then perform an install.

Android Auto sometimes disconnects when I move the phone or cable

Android Auto sometimes disconnects when I move the phone or cable. Even aggressive breaking or turns can sometimes move the cable/phone and cause this. However, during other times, even when I intentionally aggressively move thephone/cable, the connection remains intact.
After the disconnection, sometimes it reconnects automatically . During other times, I have to unplug and plug the usb cable to the phone to reconnect. In either case, I have to manually restart my music and navigation - it does not resume automatically and it is frustrating.
I do not think there is an issue with the phone port or USB cable because it works flawless when I connect it to a computer and use it as a storage device.
I tried changing cables but the issue persists. I use CM 12.1 on a GS4. - Is anyone else experiencing this frustration - Any suggestions?

Yeah it can happen if the cable can be wiggled. In my case, it came up through a rubber grommet in my console, and connected to my phone in an X-Grip. Once I changed that routing so the cable could be physically connected to the X-Grip (so it moved in unison with the phone/mount), there were no more issues.
One of my major beefs with Android is the near worthless micro USB connector. Hopefully the rumors are true and new phones soon start rolling out with USB-C.

i want it to be wireless.. there is no reason that it can't operate over wifi direct.. thats what CarPlay will be doing also, why not AA.

WiFi code is in AA.
Google hasn't enabled it yet, same as Apple pretty much.

I've had my Android Auto 2016 Buick for 2 months, and for the entire time my Samsung Galaxy Core Prime "cheapo" phone will loose connection with my car. 15 minutes was the longest it would go without having to unplug my phone and plug it back in, where it connected again with AA. What a pain! I tried 4 different cables including the original cable, and ALL would disconnect in 15 mintues or less. TODAY I fixed it. I purchased an 18 inch cable (more than long enough for my hookup) with gold connectors on Amazon for $4.99. My previous cables were 3 or 4 ft. In an hour of driving today AA worked perfectly, the first time since I bought the car. I don't know if it was the gold plated ends, or the shorter cable, but it worked flawlessly and never once disconnected. Here is what I purchased:
Ugreen Micro USB Cable, USB 2.0 A Male to Micro B Charging Cord and Sync Data Cable 1.5 Ft Gold

Thank you very much.
I had the same problem: I disconnected my Samsung S7 Android Auto from the Volkswagen Jetta Sporwagen.
I bought the cable on Amazon and solved the problem. I've tried it twice and it worked perfectly.
Thank you very much.

Shorter cable works better. I also test this.
Also it depents of the phone. I have test note 4, lg g2, nexus 5x.
The first 2 connect/disconect often. Max 30 min without disconect.
The nexus 5x (which i bought from second hand for 50€) will never loose connection. It always connect 1st time. Rock stable.

Razer phone 2 not detecting earphones nor Android auto

I recently got my USB-C port replaced by Razer because it was charging right and it out of nowhere stop syncing to Android auto. Now it charges fine but my car still won't recognize the phone, it will for a sec and then it disconnects. Also when I plug my earphones in, the audio still plays through the speakers, in option pops up to change the USB preference but it won't do it.

One thing is that some USB-C headphones don't have a AMP/DAC built-in. This is a common problem with Razer Phone 2 users, as it doesn't have one inside. So, if your headphone adapter or USB-C headphones don't have one built-in it won't work. 2, seems like Android Auto doesn't like some USB cables. Try some troubleshooting from at the "My Android Auto app isn't working" page on the Android Auto help page.

I was experiencing relatively the same thing. I tried cleaning and tightening the usb-c port on my phone. Didn't help. So I tried cleaning out the usb-c charging cable, the end that plugs into the phone. Problem solved. It works fine now, for the most part. Still will disconnect from Android Auto if I move the phone around to bunch. Or put the cable in a bind near the end that plugs into the phone.

Android auto and the adapter for the earphones used to work fine, it just happened out of nowhere before way before I sent the phone to get fixed like 2 weeks ago, the problems started last year but i think there was an update of some sort. It still won't connect, even when using the original adapter and my pc doesn't even pick up that the phone is even connected, it will just charge. I've already check the device manager to see if it was a bad driver but nothing. no matter what device i connect, it will just say "Charging connected device via USB". ive Already tried USB debugging, disable USB audio routing, cleaning it, and apps to manually control it.

P30 Pro: Disable charging when using Android Auto

Hi there!
My life does not match any pattern, that's probably why the new Smart Charge feature does not really work. I manually stop charging around 80% whenever possible. However, I frequently travel by car using Android Auto which requires me to connect the phone to the car using USB. It will ALWAYS charge to 100% when connected. Are there any options to disable charging at all? Are there USB cables which do not charge but rather provide a data only connection? Do you have any other suggestions?

You can't do it.
Usb data transfer needs +5v.
You can make a usb cable charge only, but not a usb cable data transfer only.

Question Cannot See Phone on Computer

Hi
Just plugged my Android 12 Samsung S21U into my Windows 11 PC but nothing showed on the PC. I woke the phone and tapped on the "charging" notification but nothing happened.
Went to developer settings and set the Default USB Config (which was off) to "Transfer Files"
Set USB debugging to be on too.
Still no avail.
Any help?

Is dex working? Or maybe a driver issue?

I've just installed Dex.
Samsung said I should make sure the phone is in the correct MTP when using the dialpad to type in *#0808# - which it is.
Tried installing the drivers from the Samsung website (although the UK version of the site doesn't offer any drivers) - not working.
I can connect the phone using the "link to Windows" but this won't let me connect normally.
Both Windows and the phone are fully up to date with all the latest.
Just restarted the phone and can connect to Dex, although I think it's doing it wirelessly rather than through the cable.
Yes, have tried another PC (another W11 PC).
Yes, have tried another cable (both high speed purple and low speed).
Yes, have tried another phone on both PCs and that shows fine.
What worries me a little is that Device Manager doesn't show anything connected to the PC when I connect the phone.

Turns out you need the official Samsung cable, which is USB-C to USB-C only.
My PC doesn't have a USB-C connector so looks like I'm gonna have to purchase one.
Shame they've gone the Apple route - my old Huawei P30 Pro will connect for data transfer using any old cable, of which we have loads around these days.

Pretty sure this is false. My S21U gets recognized on my PC with a normal USB A to USB C cable.

Agreed. That is just not true, I've used a USB A to C worked fine

Hmm, maybe my three cables I tried are too old?
They're from Amazon and don't particularly state they work with Samsung phones.
The plot thickens.
