USB OTG while charging? - Samsung Galaxy S9+ Questions & Answers

Apologies in advance if this has already been asked and answered.
I'm interested in using my USB-powered DAC to send an optical audio signal into my digital signal processor in my Jeep. The obvious problem I face in doing this is HEAVY battery drain.
I used to run a 2nd generation Nexus 7 tablet as my head unit in a previous vehicle, which could power by USB DAC while charging with the use of a Y-cable. This doesn't seem to be the case with my S9+.
Do any of you know of a way that I can achieve this with the S9+?
Thanks in advance for your help!

Just thought of something...
I'm guessing I could use the DeX dock to charge while using the DeX's USB port to power the DAC. That SHOULD work. Alternatively, perhaps I could wirelessly charge the S9+ while powering the DAC via OTG. Either application (if they work) would only prolong battery life, as I imagine the drain would be greater than the charge.
Anyway, still wondering if there's a way to get an old-fashioned charge while using OTG with a Y-cable or similar (powered USB hub?).

Bump. Curious if anyone has had any luck with this. Thanks in advance!

i dont think youre going to have much, if any, luck on this man. USB type C is kinda weird like that. There isnt even a jig for type c like there was with micro. Im following this one too.

There are aftermarket devices available that provide you the capability of using a USB along with a charging port and a HDMI output. I have tried it myself using a mouse and charger while connected together with the phone..... You could give it a try. That should work and is inexpensive too. I bought one and still use it sometimes for my Dex needs.

[Q] USB OTG works well with ICS, HOWEVER...

However, is there any way possible to charge your phone WHILE using the OTG adapter? They both use the 1 micro port on my phone, but I need to find a way to charge the phone while using the OTG adapter.....perhaps a micro USB splitter-type adapter?????
I was actually wondering about this myself, though I don't think a splitter-type cable would work. I'm wondering if the power connection is on separate pins than the data, though...if they don't share space then I'd think it would be possible in some fashion.

A similar problem is showing up regarding using the mhl port to output to hdmi. Though the original information indicated that the power cable was supposed to charge the phone it seems it does not on the first version (super DUMB).
I have read though that the newer version of the mhl port is 10 (I think) pins rather than the 5 of the original. The newer port DOES allow charging while output is in operation.
I suspect this will also allow an OTG cable that charges while in use.
I am not so sure about the mhl idea anymore. Only one port for everything is ok if it has enough pins/bandwidth to have a breakout box that would allow an external usb drive to be read while hdmi is being output to a screen and power is supplied to the phone. As it is now with only one-at-a-time it isn't very inspiring as the phones get closer to the power of laptops.
What would be really neat would be a box with wi-fi, and the output to hdmi and usb ports as well. A wireless breakout box. Then the charger could be over by the phone which is near the user.

500 gb hard drive connection

Hello everyone, Im not sure if this topic has been discuss in detail or not, but I have managed to connect a spare 500gb hard drive to my note 3. Here is everything I used.
I upgraded my laptop to a Samsung 250gb SSD, which provided me with a spare HDD:
http://www.amazon.com/Samsung-MZ-7T...=1387366438&sr=8-2&keywords=samsung+250gb+ssd
It comes with a cable already in it (USB 2.0) so this next item is optional, A Apricorn USB 3.0 Transger cable:
http://www.amazon.com/Apricorn-Note...qid=1387366498&sr=8-1&keywords=apricorn+clone
And lastly, it needs to connect to the phone, so I picked up this USB 3.0 OTG cable:
http://www.amazon.com/White-Color-M...7366411&sr=8-3&keywords=galaxy+note+3+usb+otg
Now here is the steps I took.
Since my HDD still had stuff on it, and it was partitioned, I had to wipe it clean. I formatted the HDD on my computer first. I formatted it to exfat. Maybe another way will work but I'm not testing it. I then hooked up all the wires accordingly and plugged it into my phone. The N3 did not recognize the file format of the HDD so I re-formatted it to the N3 standard. After that, it is as simple as plug and play. I was even able to use the stock My Files app.
Note*** obviously the SSD is not a requirement, unfortunately, I am unable to test it as it has been in my computer for several months and I dont want to risk corrupting anything. It may work with the SSD as well, although I doubt it will reach the speeds it can on a computer.
I am not rooted and did not have to download anything extra for it.

Cool. But curious as to why you would need a 500G HDD attached to the N3

This. We were using a variant setup, pushing the content via DLNA to our Xbox 360 (connected to a good ole 'dumb' tube TV). Quite enjoyable.
Damn I didnt even know you could do this
Has anyone found a way to pass through power with a splitter or something so while connecting the USB OTG cable you could still run the phone off of power without depleting the battery? I asked this same question in the Note 8 forum but no one found a way.

what format was the hdd in exFAT or NTFS ?
I use the OTG dongle to hook up my 1TB drive and play movies and TV shows directly from the drive.
(Also works with the tablet)
I formatted it to exfat. I have a 1tb external also. But it's already formatted to ntfs. And it's full so I'm not going to risk losing a thing on it.

Because it's not supposed to work that way... The OTG cable puts your device in "host" mode... so it will use the phones power to run your HDD and kill the ability to charge... there are ways to get power to the HDD so you don't drain your device battery as much but the charging thing is a native function of OTG switching.
This is what i've been using... it has HDMI out ... microUSB 5v input to run the HDD... USB port for HDD or any other USB device... (using a wireless keyboard on it right now)... and card reader ports...
You can fake this thing into trying to charge the phone by plugging in the micro USB connection first and THEN plugging the hub into the phone with the microUSB power already on... then you see the charge notification in the status bar but it still doesn't charge the device... even with the samsung 2amp charger as a power supply... the battery still drains
What about wireless charging? I Don't have a wireless charger or battery cover to test this. But this may work

That actually is a good idea to try. I'm less optimistic about that as my previous experience with wireless charging has shown that it is less efficient t getting current to the phone as a wired connection and there are some things done on your phone that even when plugged to a 2A wired connection will still drain the battery.
What about the Smart dock? With 2 USB ports an HDMI and power in?

That's the problem I'm running into... I'm running the HDMI/MHL/OTG hub... I got the HDMI out to my flat screen... OTG to a wireless keyboard... bluetooth mouse... When it all hooks up properly (you have to plug everything in the right order) the Note 3 screen shuts off and it runs as a proper CPU with output to the flat screen...but even with the samsung 2 amp charger plugged in I still lose about 1% battery every 5 minutes... better than running without the charger but that s$#t can't be good for the battery running that hard and charging at the same time AND losing the battle.

MHL cable that will also charge?

Is there an MHL cable or converter out there that will also provide power to the Note 3? I've searched a bit on amazon and there are hundreds to choose from. Most of them don't indicate whether or not they do or don't.
I picked this one up. Its only a little more than a trickle charge though. http://www.amazon.com/gp/product/B00DZJSAVY/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
I don't often recommend official accessories, given how overpriced they tend to be, but for MHL I do think you're better off with the Samsung MHL adapter which does a full 2A charge when connected to a Samsung charger. You'll pay more, but you'll sidestep all the BS sellers selling subpar gear.
If you were talking about the MHL cable/adapter itself charging the phone without an external charging input, then the only way you can get that is if you are connecting to a TV that supports the MHL standard (relatively unlikely still).

Thanks for the advice. That's the kind of info I was looking for. I'm OK with spending more of it does what I want. I see a few different Samsung ones. Is there a specific one you have?
Also I do have a new onkyo receiver that has an mhl USB port. With this could I then bypass the extra charging cable?

Thanks I just picked one up from Amazon.
There is a thread out where someone mentions one on ebay for $11. It's more of an all-in-one solution. It's called HDMI connection kit. Of the person's suggestion I bought it and it works. It is hdmi, usb, & has an SD card slot. I just happened to be looking for the thread again when I ran into your post. Will post when I find it.

There are a couple of threads that mention this, one of them is mine. That accessory puts a fairly minimal charge into the phone, it will gradually discharge when connected to that even despite the charging input.
Haven't used it alot yet but it only works with the cable it came with when using the galaxy mega... I'll look into it on my note 3.

Otg and power same time

I thought I'd throw this out here to whoever is interested in a similar install.
It's been a long while trying to figure out how to get my nexus 10 working otg without draining the battery. So, what I did was eliminate the battery all together and run it with a regulated power supply soldered to the positive and negative pins inside where the battery clip would normally go. Everything ran smooth without any errors whatsoever, then came time to test it all out by plugging the otg cable. what do you know, it worked flawlessly.
I'm able to run a usb hub with 3 flash sticks and 1 ssd hd. Hub must be powered separate with the power plug. This is a perfect setup for my situation since the tablet is installed in my truck and I wasn't too happy with the idea of having a lithium battery inside on hot summer days.
I'm pretty sure this method could even work while keeping the battery installed inside connecting the leads to a double throw relay along with a separate plug that would separate the two power sources.
Testing also passed while plugging it to the pc foe file access and debugging mode.
Hope this helps some people. Don't be shy if you need to ask any questions on this project.
Later
A pc usb port puts out 5v 500ma wich barely keeps the Nexus10 battery level
The ac charger puts out 5v 2amps
I hope your power supply is putting out same amps..

Hello Asylum,
I'm indeed interested in your setup, since OTG+charging is not possible with traditional methods (even pogo cable doesn't work along with OTG).
If I clearly understood, you opened your nexus, removed the battery and directly soldered cables + and - ?
Is it a complex operation ? (in particular to open the nexus and close it without tearing it down).
Do you have a photo of your installation ?
Thank you for your help :cyclops:
LeDuke
I'm also interested in this setup and would love to see pics!
Not to sound like a d1ck or anything, but I have a alternative. Just make a otg cable with a male and female USB ends and just hook up the male end to power lines. Them you can just use a regular USB wallwart to profile power to your drive.
I used this method to run a 1tb external HDD.

USB C type adapter cable that allows charge the phone and listen to music at once?

I was looking for the type of cable that allow to charge and use cable headphones( C type) . There are solutions for Iphone 7 but I have not come across any for Android. What's the situation in regards HTC U11?
I did the same search for about an hour one night, I didn't find anything either. I expected many options out of China. I was a bit surprised. Maybe the plug cannot put out and accept power at the same time on Android?
I seen a thread last night that someone bought something like https://www.amazon.com/Goliton-Fema...qid=1496202880&sr=8-44&keywords=usb+c+adapter and https://www.amazon.com/multiport-US...qid=1496203314&sr=8-14&keywords=USB-c+PD+Port

I found this where the blogger talks a out possible schematics for usb c that enables both charge and music listening at the same time. Article is written in 2016.
Because I saw such adapters for iphone 7 maybe apple worked it out how to do it on lighting cable. Anyway here is a link : http://pocketnow.com/2016/09/08/the-impending-horror-of-usb-type-c-audio-adapters
I read something about type C that claims that splitting the port for simultaneous use and charging may be technically challenging for some reason. I tried looking for that article, but couldn't find it again. Regardless, if I need to charge while listening to my earphones, I temporarily use Bluetooth and one of these adapters: (https://www.amazon.com/gp/aw/d/B00MJMV0GU/ref=psdcmw_1293687011_t1_B01NCSFAAO)
to continue using my normal earphones until my phone fully charges. I really like my normal earphones and don't want to use Bluetooth ones, so I use this adapter till the phone's charged.

Isn't that a rushed decision by android manufacturers to replace 3.5 jack without exploring give situation ?! I have already two decent pair of earbuds and will have the third bundled with handset.
Did you buy that Bluetooth adaptor and using by any chance? If so are you fully satisfied?

It is a rushed decision. What I'm curious about is if they used the anonymous usage data to make this decision. If so, it's possible that people who used both the headphone jack and charged their phone at the same time under-represented themselves by opting out of anonymous usage data.
Companies like Samsung and LG are "throw as many features into the phone as possible!" companies; making them more likely to be the last major manufacturers to get rid of the headphone jack.
3.5 jack on phones is dying off just like removable batteries. It's that simple.
You get a free included adaptor - so this is really not an issue as I see it.

Could be they used wrong audience for that purpose. For instance apple by getting rid of 3.5 jack and patenting lighting port makes a lot of money. And that makes a sense because every company that wants to make lighting cable they pay apple. I don't know what is the situation with 3.5 jack and USB C type but that could also be related to Bluetooth earbuds/head[hone market. Just guessing.
I use my G5 connected to USB Type C for charging, while also using the 3.5mm headset jack connected to the car's AUX Audio input for playing Music, Navigation, Waze. I was hoping there would be an adapter somewhere (for phones like the U11) that would allow it to charge while also being able to connect to 3.5mm audio.
Hi got redirected here by @Lock and Load. Seems it is possible to do manual cable, but have to use data + - for charging (from what i read). That means 500mA charging only. I will try a cable when i get some time. Can a usb-c hub be used? Has anyone tried? Would save a lot of messing around.

Investigated the same option you did. And mailed some sellers about it.
The Y+cables won't charge your phone, only the peripheral which you plugged in the other USB Port. And a power bank or. Charger in the other port.
