MHL Adaptor Charging Issues (500MaH Max)

Morning All,
Having a problem with charging via MHL adaptor - I have my phone connected via MHL to a Pioneer AppRadio2. Getting the error message saying the phone is drawing more current than the charger can provide, so over a long journey - the charge drops significantly.
I have done some research and found when using and MHL adaptor, the phone sees it as charging via USB which has a max draw of 500MaH. I am currently using a 2amp charger but the phone cannot draw this current due to its own software limitation. It is possible to bridge (short) the 2 USB wires in the cable (data in/out) to trick the device into thinking it is a AC charger. Unfortunately this is not a suitable solution because the 2 USB wires are used to transfer data to the MHL adaptor.
I have found some kernels remove this limitation, or make the phone think all chargers are AC chargers. Does anyone know how which kernel can do this and would be compatible with Android Revolution 6.6.7 (current ROM). Important thing is that video out still works, and also that the phone actually charges!
Any help would really be appreciated!

Modified Faux kernel has this, you can find it here. I'm quite satisfied with it.
There are probably other kernels that have this, Bricked perhaps, but I'm not using them so I can't confirm

[Q] MHL Adapter - charging but still dropping battery

I bought a MHL Adapter (microUSB - HDMI) from DealExterme [1].
It works well, even without power, but when I put the original charger (2A), the S4 starts charging but can't even hold the charge. The charge will slowly dropping over time.
Is this normal?

Yeah this tends to happen when the phone is draining more battery then the charger is charging the phone.

Even with de 2A charger? This is a lot of power!
Not sure if that's what happens or the MHL adapter that doesn't pass the full 2A for the S4.
Someone who has the original Samsung MHL adapter can tell if the same thing happens?

I don't have this problem with the official oem samsung adapter.... Even in the manual it says to use a 2a charger from samsung to get power...

Great to know that!
Can you confirm that by using the official Samsung adapter + 2A charger the phone battery doesn't drop?
Other questions:
1. What's your S4? I9500 or I9505?
2. What's your firmware? Stock? Google Edition? Other?
3. What's your kernel? Stock?

Firstly, I don't have an S4, but I do have a Note 2 which also comes with a 2A charger. In my experience when using an MHL adapter the phone will only charge very slowly at best. If you are making it work hard, the battery will slowly drain. If I understand correctly, this is because of a limitation regarding how much power a normal USB port can supply.
When your phone is connected to a wall charger, go into settings and 'more' and tap 'battery'. At the top it should tell you it's charging, and that the type is A/C. Now plug in your MHL adapter, and plug the charger into the MHL adapter and go back into the same settings page - on my Note 2 (and also my HTC Sensation), this page now shows 'USB' instead of A/C. If the same is true with the S4 (and I'm pretty sure it will be), this is the source of the problem. It wouldn't matter if the charger was 1A, 2A or even more, the phone will only draw so much from what it thinks is a USB port. It's a pain, but there you go.
When you connect your phone to a TV via MHL, try lowering the screen brightness on the phone to minimum manually. If you have a quick search, there's also an app on here that should allow you to power of the S4's screen completely and still allow you to output a picture to the TV. Sorry, I don't have the link to hand.

Its the cable. The MHL cable is just a poor cable, if it says USB like Ouzo says then you would need to short the data pins on it or use a charge only cable (the charge only cable may not even work though).

I get the part that my MHL adapter might be delivering energy in "USB mode" instead of "AC mode".
My big question is: by the report of "big samm", it seems that the original Samsung MHL adapter does not suffer from this problem. Ie: it delivers energy in "AC mode". Is this true? I can trust and spend $ 40 on it?
If anyone can confirm, I appreciate!

I would just go for a real one from samsung so that way you won't have any problems with the battery charging because it's designed to charge + play

The problem is that I still don't have a confirmation whether in fact the original MHL Adapter solves this problem and the investment is very high (4x the price I paid for the alternate adapter).
I dont know if it's really "designed to charge + play."

The app is Screen Standby. It freezes and closes when the wizard asks to verify root + busybox. Ignoring this part of the wizard it works but when it make phone screen black all my touches start to have a delay of 8s. Any movement on the screen takes 8 seconds to be played on TV. Totally buggy.

Ah, ok, I control my phone with a Bluetooth keyboard with built in mouse (works very well for many things, but not games designed for touch input, though there is an app to help with this in the Play store), I didn't realise you'd still want to touch the screen.
Maybe someone with a genuine Samsung MHL adapter can tell us what the battery screen shows when theirs
is in use with the Samsung charger attached. Also, you could ask nztechfreak, he knows all about such things....

Ok i just checked the manual again and it says " Use only Samsung approved chargers (over1a) there you go...

This is simply beyond ridiculous.
First, let me clarify for couple people that barged in here. This problem has nothing to do with official/unofficial stuff.
I have genuine Samsung Galaxy S4, I have genuine samsung mhl 2.0 adapter, and I have genuine wall charger (2000 mA) as well as the usb cable. You can't go more official than that.
And EVEN with all that, the battery is being drained quickly, despite the mhl adapter being connected with the wall charger. This is simply beyond belief. OBVIOUSLY the phone will be on high usage when the mhl adapter is being connected, because it's the whole point, so did Samsung actually took care of the bigger battery drainage at this point, in connection with charging current? Nope.
You cannot go couple hours before the phone is dead, despite being "in charge mode". The customer uses official samsung stuff, it connects the charging cable, and yet the phone is not charging (just the drainage is slower).
If I met this Samsung CEO that is the first one on the stage to present the cashing cow everytime new galaxy is being presented (well if that's the case he is the first one to ask about his product ain't that correct?), I would ask him about this and would keep nagging this problem to him until his ears would bleed, and he would promise it will be fixed in the next update of mhl 2.0 adapter.
And just to make it clear, the problem is not with the battery drainage, but with the current being suplied from the mhl adapter. If it was 2000 mA, as it is when you connect the phone directly to the wall charger, there would be no problem. Instead it is 500 mA, as it is when you connect the phone to USB port, and because of that, the phone is dead in the manner of hours, despite "charging" (pun intended).
Amazing.

i tested i9505 with his original wall charger.
Original charger with original usb cable consumption is 1200mah
Original charger with other usb cable consumption is 460 mah
So first is important to use original usb cable.
Then i tested compatible mhl cable with original charger, its consumption is 300mah.
So the problem is the slow charging even with kernel with fast charging.
I ordered original mhl adapter, i will test it when come and post result

I'm late to the show, but will report my experience as well.
Last month on stock TW MDK using all genuine Samsung including a MHL 2.0 adapter, I also experienced battery depletion and a hot phone. I failed to check the Status to see whether it was charging at APC or USB rate.
I attributed it to the screen being on and the phone streaming movie data across the cell network.
Just now, I plugged the MHL 2.0 adapter in, then the charger, but not into HDMI. It shows USB for two seconds then it says AC on the phone Status. Same thing a couple times in a row. Plugging the charger directly into the phone goes immediately to AC charging.

[Q] OTG and Charging

I recently got a Nexus 5 to replace my old Nexus S and really like it. I am having one challenge that I was hoping for help on:
I have got OTG working with stickmount fine, but I am trying to use this Y-cable to charge while using it and I can't get the phone to charge from the cable at all (with or without a USB drive connected). I have been able to get other, non-Nexus's to charge from the cable so it isn't the cable that is the problem.
I am rooted but running a stock kernel and rom - any ideas why it might not be working or if there is a custom kernel that has enabled the capability otherwise disabled in the phone?

Probably you need a modified Kernel like Nexus 7

I had OTG charging on my Galaxy Nexus as well as the N7. I just tried it too on my N5 with Elemental X kernel, no go. That's odd no one has come out with this feature yet if that's the case as I'm sure it's very sought after especially with people who have the 16gb model like myself that hook up to external hard drives to save space on the phone but they need external power.

Otg + Charging is also very useful when you are playing games using GamePad

If you are using a USB Connection Game Pad via OTG, graphics heavy games use too much battery and usually you can not play for long. This also increases the importance of such kernel for Nexus 5 as well. Nexus 5 have smaller battery but it can play decent Graphics.
I do not like Game Pads with Bluetooth connectivity as they have control latency or lag and your moves are not as quick as even the touch screen, where as you use Game Pads to improve your control moves and probably make them better than touch screen.

I think that Nexus 5 USB Port is 5 Pin and not 11 pin like Galaxy S4 or Galaxy S3. Can someone please confirm this?
If this is the case will be still be able to Charger Phone and do OTG concurrently or simultaneously ?

Yes but I believe it's something that has to be addressed at the kernel level.
I use a powered USB hub and even though the phone doesn't show any charging animations, going into the battery info screen shows it is charging (though it doesn't say usb or ac, just charging)
from what I have seen it's even less than trickle charge.
USB flash drive mounted.
Screen off
Battery goes up about 1% every 10-15 minutes.
So clearly current is being passed from the hub to the phone. Just not a lot

I am not sure but can we use QI Wireless charging along OTG. I have read somewhere that it charges but there is a bug in Kernel due to which it does not know that battery is being charged there is no animation or text to show that battery is being charged. Another concern is that if OS does not know about charging and battery is being charged is it not dangerous can it not overcharge and below the battery etc.?

I use exactly the same Y-cable from amazon as avalpert. I connect my USB 2.5" harddisk first at the Nexus charger and let it spin up. Then i connect the OTG cable to my Nexus 5 (rooted stock ROM & stock kernel). The battery icon in the status bar has no charging animation but in settings it says its charging. Around 1% in 5-10min. Even if the screen is on.
@ avalpert: U could check the current of your usb drive in the manufacturer's datasheet and subtract this from the current, your charger is able to provide. My Nexus 5 charger can output max. 1.2A at 5V. Maybe you're using another model and there is just little current left to charge as Alex remarked.

But the difference is I was only powering a flash drive which uses next to no power. And still only 1% every 10-15 minutes.
My best guess is that because otg is enabled. The kernel is not able to tell what type of charging type (ac or USB) is connected so it just enables trickle charge as not to cause any problems

I can confirm this, I use a powered 7 port USB 2.0 hub, and with the original PS: no charging.
Now I took another PS that puts out 2.14-1.7A @ 6-7.5 VDC, and hey presto, charging the phone!
No indicator in the status bar (top screen), but when checking the battery status it clearly states "CHARGING" (see picture OPLADEN 95%)!!
And it charges pretty fast too.....
The mouse is working, as wel as the USB stick is recognized and working!!
The ONLY worry is about the charge....... is 6-7.5 V a battery killer? :fingers-crossed:
Anyone?

May be we can use fixed output voltage and amp adapter just like the following
http://www.amazon.co.uk/2000mah-Ada...ds=5V+2A+2000ma+AC+Power+Adapter+Wall+Charger
I know it is up to the device (Nexus 5) that how much load it will put on the adapter to consumer out of 2000ma or 2A. On the other hand I have read somewhere that even most 2000mA USB Chargers just give 500mA in the beginning and due to some data pins activity they start generating 2000mA. If this is the case then Nexus 5 will force only 500mA or so from the charger that it is not compatible with. If we use some adapter that generates constant 5V 2000mA irrelevant of communication on data pins like the ones with 3.5mm pin which does not have any data pins, at least we are guaranteed that, at least full power is coming out of the adapter at all times.

I am given to understand that it has nothing to do with the "intelligence" of the charger, but with basic electrical principles.
That would imlpicate that if a device requires 500 mA, the charger will supply 500 mA, if the device would require 3000mA, then it would supply 2000 mA, being it's maximum current (flow).
As far as I know, a powersource ONLY generates a flow (Amps) up to it's maximum limit, if it is connected to a consumer (device). No connected device / consumer leaves no flow to be generated.
Please correct me if I'm wrong.
Added to my little test earlier today: The phone didn't get hot, at most it would be slightly less cool..... for the PS the same.

[Q] USB charging of WiFi model

I tried the cord that came with the tablet, and my other USB cables - same results with all. My Note Pro won't charge via USB at all - when I plug it in battery status says "not charging" and it keeps discharging, while idling with screen off. Only AC adapter works and battery status changes to "charging". Any ideas?

You can't charge the tablet off s usb port. Draws too much current. Some motherboards have an option to turn on a special charging function for a usb port, but if you had that you would probably know.
Your stuck with the wall charger.

Stock kernel on the Xperia Tab Z must have USB charging enabled. This is an exception rather than a norm I would think, with OEMs probably choosing to disable this as a safety measure (or so i've read).
Until a custom kernel is developed for the Note Pro we'll probably not see charging over USB.

The problem is still the max output from the USB port, which is 5V 0.5A , you'll notice that the charger for the this tablet is 5.3V 2A.
I'm an electrical engineer not a computer engineer, so I'm not sure how a kernel would change the max output current supplied by the PC. This has actually piqued my interest, I'm going to do some tests and see how much current the port can push. I'm betting the data lines on the plug send some information about what's being charged.
Maybe I'll build an adapter that that let's the tab pull a full 2A from the port.

Does it make a difference if it's USB 2.0 or USB 3.0 port?

Normal USB 2.0 is 500mv, USB 3.0 is 900mv. Some motherboards can push this up to 2000mv, usually a red usb port

The nature of my kernel comment stems from my Nexus 4 experience with a custom kernel which has a setting to enable usb fast charge (Franco kernel with his FKU application).

This review says Note Pro 12.2 can be charged via USB - it's just slow. As I mentioned in the OP - when I plug it in via USB cable the battery status says "not charging" - could it be it's actually charging, but due to low current the device itself doesn't recognize it's being charged?

Just plug it in for a few hours and see if it increased your battery level... done.

It kinda works - with tablet completely idle and screen off it charged about 4% in 1.5 hours via USB 3.0....don't think that's helpful to anybody. Hopefully, someone finds a way to push more current through USB 3.0 port. Would be nice to eliminate the need to use AC charger.

I had mine hooked up to my laptop (Asus N76VB), it didn't charge according to the indicators (neither do my TabPro 8.4, Tab 3 and Tab 2, nor my TF700T), but the battery didn't drain either while I was using it. It stayed at 56% for 5 hours whilst browsing, which it really wouldn't do normally. USB 3.0, no additional settings enabled on the laptop, all Sync and GPS turned off on the tablet.
My TF700T literally said in the manual: "Charging from USB can only be done with the device turned off." I'm sure that applies to these tablets as well.
On the upside, my 15600mAh aSolar powerpack charges the device! :victory: (It can't charge my Tab 2 or TF700). I'm really, really pleased about that!

Regardless, for $9 bux, its worth checking out for anyone who is interested.

If what you're saying is true then this is a Pixel stand for a fraction of the cost. That's pretty awesome.

for 10 bucks I'll give it a try. Worse comes to worse I can use it to charge other phones in the house.

I have one on the way from China. Will report back when it arrives.

Dumb question: does the generic AC USB plug being used with this stand still need to be USB-PD capable?

I think it only needs to be quick charge 2.0/3.0 capable. Didn't the OP say he had trouble using the original pixel charger that came with his phone? I actually ran into issues using my original pixel wall charger with some wireless car charger mounts. They worked fine with QC chargers.

I ordered one too for 10 bucks it's worth a try.

They sent two of these to me. Both show max 8.4 watts no matter what cable/plug I use and I have many. It also does not present itself as a Pixel Stand - those features are not available.
To add, I noticed the stands get in a state that bounces power on/off very quickly and doesn't stop. I would avoid these.

What do you mean it bounces on and off? Like it says charging and then says it's not charging at the bottom?

Yes, bouncing like a bad port on a router/switch. It goes from charging/not charging very quickly over and over after about 3-5 minutes of charging.

mine arrived today, I can also confirm slow charging and no pixel stand functionality no matter what adapter or cable I use

Sorry for any delayed responses here (holiday) though I have just caught these testing results.
I just received an additional (2) of the same chargers and all seem to charge fine here. (Pixel 4 XL)
All being used with Samsung AC Fast Charging AC adapter.
Check to see if the AC adapter you are using has both 5v & 9v output. (Must have 9v for the FAST to charge)
-
Can you post a photo of the AC adapter that you are using ? (all photos could be of assistance here.)
The stand itself is 20w so fast charging would more or less come down to the AC plug.
** Keep in mind that the OG cable and AC charger plug that came with the PIXEL phone is not compatible
with this charger that will hit at SLOW. (mentioned in OG post)

I tried several, from the OEM to choetech to aukey to zte. I used the cable it came with, OEM a to c, OEM c, third party c; i tried both type c and qc3 chargers...all with no success. I wouldn't think the pixel stand feature shouldn't have anything to do with charging speed, though I can't say for sure

I believe the PIXEL stand software features only become enabled when detecting a FAST CHARGE at 13.5w.
(which is capable when using AC adapters of 9v & more)
The only AC adapter I personally have found to be non working was THE OG stuff & USB C to USB C
Most USB C to USB A seemed to work with no hitch.
USB C adapters, had no issues with them either. worked fine.
Can you snap of picture of the AC adapter labels. ?
See if we could narrow down the issues.
also one last .... check the actual charging wattage using the app Inware. (Battery Tab)
The lock screen charging message will ONLY show Charging Wireless - not rapid charging (which is easily misleading) though is running at FAST WIRELESS CHARGING speeds.

Using with LG stylo 5 fast adapter and the chargingspeed is fast. between 1 1/2 hours - 2 hours total. Using with Usb C to Usb A cable 3 ft.
My only issue really was trying to get the extra software up and running. I couldn't figure out why or how to do it. strange as I moved my pixel phone upwards while resting on the dock all of a sudden it just appeared out of nowhere to activate all the extras. weird device for sure but works.

---- II personally didnt even know there was such software initially for as it only showed up about an hour later sitting on the charger. Please let us know how it all goes and if you have any trouble along the way.
Knowing they are knock offs, I am kind of curious to see what the long run holds. Thanks for the info.

forgot to ask, can you share the specs of your LG charger for us ? All the info helps build the list of do's and donts. Thanks..

I am using the original lg fast adapter plug.
9.0v 1.8amps and 5.0v 1.8 amps. working well with stand.

I ordered a pair of these stands as well and am still waiting for them.
But I did order this one before that from amazon https://www.amazon.ca/gp/product/B07Y9J68TC
and it also gets recognized as a pixel stand. (only when using samsung or QC3 adapters though)
