Hello there,
I bought Samsung's MHL to HDMI Adapter (http://www.amazon.com/Samsung-MHL-HDMI-Adapter-Packaging/dp/B005LGUDKK/ref=pd_cp_cps_1) for my at&t SGS2, video and audio worked on my HDTV without hassle, but it did not actually charge phone's battery. when it was hooked up it kept 'rising bar' on battery icon in notification area and I was under impression it's truly charging as well playing the video on my TV, but it showed 30% batter warning that's when I realized it's not charging but faking to show charging!
Is is normal or abnormal, but I read in wiki or somewhere when it's hooked on MHL to HDMI Adapter/dongle SSGS2's designed to charge the battery as well, I need to your help to determine if I have a faulty one or I should turn on/off anything on phone!
Thanks in advance!
It will only charge your phone if the TV is a MHL compliant TV. I don't think any TVs on the market are compliant yet.
There should be a spot on the adapter to plug your charger into. That is the solution for non-compliant TVs. Did you plug your charger into the adapter?

Thanks quarlow for quick reply. Yes I indeed plugged the charger into Adapter in order for it to work, that worked flawlessly, but the question is why the battery icon on my phone was showing 'charging bar' while it was not actually charging, that's mysterious.
My TV may be not MHL complaint as it's 2 yrs old already, but MHL complaint TV's don't need the MHL adapter be powered by external chargers, if I am right.
Thanks!
I too have an MHL adapter but it isn't the official "Samsung" one, but it will charge the phone overnight, but I've never left the device plugged into a tv and the adapter for an extended period of time.
I imagine that the adapter needs to draw power to send an image out to the TV, and the phone simply assumes that a charger is plugged in but rather than actually getting a charge the power is being diverted into the MHL adapter, and maybe a little bit is going to the phone but not enough to offset the drain of displaying an image on an HDTV.
I'll give it a test drive tonight and see if I get any different results, but I bet I have the same result.

Much appreciated !
From what I can tell the stock charger is only 700MA and will charge the phone slowly when not in use, however if it is inuse I am sure it will only be able to keep up with the power used.
I use an HTC charger most of the time it is a 1000MA charger and seems to be a bit faster. I have not tried this with the MHL connector tho.

I believe this is your answer as well. I did not have the opportunity to test drive the MHL adapter last night, but what I would suggest is turning off whatever you aren't using while streaming. Check out the link below, and the last review for a similar problem from another MHL adapter, although MHL allows charging I imagine if you read the spec on it (the tech spec), it probably only supports 500 mAh max. Although it costs $100 to read the draft spec (which is stupid).
I will find out if I experience the same drain as well but I imagine what is happening is the Wifi/Data connection is draining faster than the charge is going into the battery, which is probably why standard use doesn't cause a problem. However streaming coupled with whatever else is going on is probably the culprit. So I'd suggest if you are going to stream anything while connected to disable non essential services (Sync, other data connections, bluetooth) and clear RAM so only what you want is actually running.

So you mean if phone is hooked up with MHL adapter while it's not actually streaming , the battery percentage should go up (meaning charging) like 8% ->to 9% -> 10% ? I can try this.
I know the MHL adapter will charge your phone if you aren't streaming, I had mine plugged in sent text message, watched a video clip I shot, looked through pictures, and left it plugged in. I also used to charge my phone via the MHL adapter (charger into MHL into phone) regularly but the charger kept popping out of my adapter if I checked my phone.
I'll look into it more this weekend and get back with you about it.
Can confirm this is indeed a problem. Would recommend under clocking the processor
Until it's unbearable and try again.
My processor is oc'd on demand but it drained it really fast. Probably a glitch in their version of GB.
Sorry I don't have better news!

Thanks Guys!
I did kinda experiment, MHL adapter is indeed charging the battery while streaming, but battery drains faster than being charged, this is the outcome.
1. I plugged the phone while it's not streaming ..battery percentage increased from 78 ->79->80% and so on.
2. I took the phone off the MHL adapter and played the same video (flash based) it drained 10% of battery in 20 minutes.
3. I hooked the MHL adapter/charger and streamed the same video (flash based) it drained 5% of battery in 20 minutes.
I would like to conclude, MHL adapter charged the battery, but flash based video streaming drained the battery faster than the rate in which the battery was being charged.

I recently bought a monoprice MHL adapter. Hooked everything up, works.
As we all know, you need to feed the adapter with a standard microusb power cable. I have a 1 amp (max power on a micro as far as I know)
While it DOES charge my phone (the charge indicator is on), my battery charge actually goes DOWN during energy demanding applications (like streaming a movie online or something). It goes back up when not in frivolous use.
This is a big problem, the whole point of MHL I thought was to charge at the same time as the phone is getting heavily used.
Anyone else have this issue? Could it be the monoprice adapter is crap, throttling the power that it gets from the charger? Should i be getting an HTC one?
Nothing is defective, this is normal. If I'm not mistaken, the MHL adapter is just that, an adapter. MHL is a new connection that few to no TVs include which is why the adapter is out. The usb cable is powering both the adapter and phone at the same time, so that charge is getting split.
I'm not 100% on this here: But I believe TVs with the real deal MHL built in would run a HDMI to micro-usb cable without the adapter and would then provide a full charge to the phone. The other benefit with this is the TV remote I think can also control the phone so you don't have to get up to touch it. It's just unfortunate that we don't get the full charge on the adapter too.

Just the other night I played two full length HD movies through my HTC MHL adapter. Before I began the battery was at 98% charge. At the end of the 4+ hours, the battery was still at 98%. I would say that's pretty good!
So it is an issue with the monoprice adapter... get what ya pay for

Nope. I would say its an issue with the intense apps you are using. I played a 1 hour HD tv show using Diceplayer out to a 50 inch tv. I tried using an old portable battery connected to the monoprice adapter and I was worried that it wouldn't pass current fast enough. After that hour I was surprised to note my phone gained in charge from yellow to green, and my portable battery was hardly impacted. I am pretty certain I could get at least 3 hours of playback and maybe as much as 10 from this setup. I'm really impressed.
I have the T-Mobile MHL adaptor and I have watched a couple of BLU-RAY Rips that were being displayed in 3D on my Evo's screen. My battery level didn't drop while watching the movies. Yours has to be either a faulty charger, or a faulty MHL adaptor....
Even my HTC video-out dongle that I bought for my Touch Pro or Touch Pro 2 (don't remember which) would keep the battery at a constant level when watching movies. The charger was optional with it though, it worked fine with out it.

I've noticed that getting a replacement or getting another brand appears to be your stock answer whenever anyone's having problems charging, getting a picture, or getting substandard quality. I'm concerned that you're going to make someone spend money or get a replacement unnecessarily.
If you read his e-mail - you'd note that he's not only playing blu-ray rips (like I've done) - but he's streaming them. It's possible that the excessive power loss is due to his internet connection - even a poor internet connection causes our phones to lose power quickly. I suspect that with any adapter - net intensive apps plus the requirement to power the TV output, would overwhelm the charger.

That is not necessarily true - although I'm sure a week signal would cause the radio to work harder. One of the two movies that I played back-to-back was streaming through a HD Netfix app. Streaming did not have any more impact on my battery than did playing a movie from the SD card. That streaming was done through 3G.
Yes, a poor internet connection could also be the cause although it isn't likely. I'm sorry, I just assume that every one has a wireless router in their home these days, and that may not be the case. So to those who don't have a wireless router in their home, that could be their issue. If you do have a wireless router and are still having issues, then its a faulty device (hdmi cable, MHL adaptor, micro-USB cable, or wall charger/power supply). I can stream just fine with excellent sound, picture, and not lose battery life; so it can be done with the right, properly functioning components

I have the T-Mobile one, too, and my phone charges while using it. I've used PowerAmp, Pandora, NetFlix and my SlingPlayer app with the MHL adapter and my phone charges with either one.
That's on WiFi. If I'm using the 4G, the phone will run warm and charge very slowly, but it still will not drain. Mine looks like this:

Crap, I had found a great discussion about this exact issue yesterday but now I can't find it to share here - will keep looking. It related to the Samsung SGII, but same topic...
Basically what they were saying is the kernel limits the amount of charge the phone can accept to protect the battery from getting to hot, blowing up or over charging. Not sure if the limit is universal but for the phone they were discussing had a limit of 650 mah (or whatever the unit would be). They also clarified a wall charger only puts out 500 as a maximum and a usb cable (such as charging from computer) was lower - can't remember the value, I think they said 450?
They continued to explain that that charge would be split between the adapter and phone and if the phone was working so hard, it would discharge because it was using more power than it was gaining.
I can imagine some adapters are more efficient than others. But I'll see if I can find the discussion again. They explained it a lot better than I could and I'm only going off memory right now.
EDIT: Found it! Near the bottom, 3waygeek explains it pretty well:

The explination in that link clearly has some speculation and must be flawed in some manner. Otherwise, how was my battery able to maintain the exact same % of charge after 4+ hours of playing/streaming movies to my HDTV?
I think the concept is probably sound, but the numbers must be off.

I agree, there must be some speculation in it. But at the same time, I wouldn't doubt some adapters use more/less power than others too and I'm sure phone's cpu speed and signal strength and other performance governing factors make a difference too.
I've heard that samsung's have very poor charges. I don't think that should apply for HTC stuff.
So I now tried to stream some music via wifi. Started at 63% or so battery life. Looked back at my phone after an hour, its around 50 something percent. Streamed via mhl to my reciever
im using an htc charger (its 1 Amp), also have a 1 Amp monoprice charger. I don't think they are defective.
Perhaps the culprit is the battery? My standard charges have been slow since I bought the thing on launch day (though I rarely notice cause I usually just plug it in before sleep and its full when i wake up). Any way to really test this? Without having to pull out my multimeter... I mean, theres got to be an app out there that can at least estimate mAh ussage and charge based on whats going on, nothing that i've found. I'm usually conscientious about these things

I'm getting similar results streaming music via Pandora on a wifi signal. After 40 minutes, my phone went from 30% to about 25%. This was using the HTC charger.
I then switched to a portable battery instead of the charger and played about 40 minutes again. I got similar results, the phone battery went to about 20%. The portable battery was just about untouched - leading me to believe that the adapter doesn't pull much from the external power source.
In short - my monoprice MHL adapter charges my phone while playing HD movies on my SD card, but not when I stream. This is not enough to bother me - but at some point in the future when prices come down, I may decide to buy a second adapter if it's true they charge better.
It'd be nice if those with adapters that claim they can stream and still charge - would actually run the test above and confirm. Because otherwise - it's just anecdotal evidence.
To be specific, I streamed Pandora through wifi with auto backlighting, the screen set to stay on, and all radios enabled.
I did one more test. I aquired a 2.1 amp charger meant for the IPAD to see if it would allow this phone to charge while using the MHL adapter and streaming pandora.
Nope. After a half hour of streaming Pandora, my battery's capacity dropped 7%.
I also have a MHL adapter from MP and have the same "issue" My phone's battery will slowly go down when I stream from netflix.

Not quite, the adapter requires power so you also need to plug a standard charger into it, plus you need an HDMI cable to go from the adapter to the TV. Frankly for now it's a more cumbersome solution than micro-HDMI as in the previous EVO (& Moto phones), since that was a 1 cable/adapter solution (unless you also wanted to charge the phone)...
In the future TVs will have MHL ports tho and you'll be able to output from phone to TV AND charge off the same MHL/USB-to-MHL/HDMI cable. For now tho, we have to live with the MHL to HDMI adapter with a charger plugged into it. Personally I think HTC & Samsung jumped the gun with this, by the time people have TVs that make MHL a better option than microHDMI we'll already be looking at the next generation of phones (if not the one after that).
P.S. I don't think it's necessary to bump three old threads on the same topic to get an answer to a question that has in fact already been answered on these boards. Just sayin'... Search button works.

That... Doesn't exist. The EVO 3D doesn't even have a microHDMI port, and standard HDMI of any kind doesn't transfer power (that's what MHL is for, to eventually allow a single cable power/video solution, duh).

The Evo 4G uses Micro HDMI. The Evo 3D uses MHL.
They are down to $14.02 on Monoprice now.
ONLY USB power
Is it just me - or using this monoprice adapter makes the phone charge in USB mode and not AC mode (50-90% reduction in charging current?).
I've tried several of my chargers that always report "AC charging" under settings, about phone, battery use (1000mA?)
but as soon as I plug in the monoprice MHL, it drops to "USB charging" (100mA - 500mA)?
I bought two of these Monoprice MHL adapters and both seem to do this. I've tried with four or five different micro-usb AC chargers and one DC cigarette lighter charger... all to the same result.
The result, for me, is that the phone charges at 1/10 the speed of normal - indeed depleting my battery even though it's plugged in to the charger (via the MHL adapter). Even turning my screen brightness all the way down and turning off all non-essential radios... still results in me not being able to watch a full movie before battery dies.
Is it just me or does MHL suck compared to the easy microHDMI of the evo4g?
Yeah it's kinda more cumbersome, eventually when TVs actually support MHL and we don't need these pass thru adapters then it'll be great as it'll be a single cable solution... It was implemented way too early on phones tho.

I can definitely confirm you're limited to USB power using the Monoprice adapter. BUT I'm definitely not losing battery power that fast. In fact, if I'm playing movies off the memory card - I'm still charging the phone. If I stream something while connected, my battery will drain - but nowhere near as bad as you're reporting.
I guess your ability to charge while playing from SD card is to be expected. Radios/streaming take a lot of power.
My normal use-case is 4G streaming netflix, hulu, youtube, hbo go via the MHL/HDMI to a pico projector. And it kills the battery REAL quick even with screen backlight to lowest, bluetooth and wifi off. I'll start experimenting with underclocking undervolting... to find the sweet spot of acceptable fps playback but little enough power to get under that threshold of charge from the adapter.
Anyone recommend a good program to see mA currently being used vs. mA drawn from charger?
Yeah, MHL seems like a great idea - except that not a single TV or device provides it. To me, seems a bad / annoying decision like providing USB5 in 2011... sure it's a cool technology - but isn't the point to be able to interface with EXISTING infrastructure? Annoying also that we NEED to plug in charger to use it.
I have the HDMI out hooked to a 7" monitor screen in my truck using the HTC MHL adaptor & the stock 1 amp A/C charger. I have A/C power in my truck & the charger is plugged into that, but my battery widget is reporting it is USB charging for some reason.
I have my screen at 25% brightness & NOTHING else running except Act1 to show a movie. I am using the HTC 2750 extended battery/cover.
Even though it shows it is charging, it discharges a LOT while playing a movie. I have had two Rezounds and both did the same thing.
I was dropping off my Wife this morning and she was watching a movie for close to 1/2 hour & my battery dropped almost 10% during that time. I started at 99% charged & by the time I dropped her off it was at 90% in less than 1/2 hour.
Is there a more powerful charger I can buy that will fix this problem??

The charging is actually controlled by the phone. It drip feeds the battery. I'm looking for the tool I saw the other day to change that setting. As soon as I find it again, I'll post it.

That would be awesome, thankyou for your help -I really appreciate it.

sounds like the mhl adapter doesn't have the wiring setup right to trigger the 1A draw by the phone... maybe figure out which wires needs to be crossed? We've had this problem with similar non-oem wall charger/ car charger setups where people would go in and solder the middle two pins of the usb port together to trigger the charging mode. While the AC adapter you're using is working right, the MHL piece might not be setup right.
Where did you get your MHL adapter with hdmi out and charger in plugs?
Thanks.

I got mine off Verizon Wireless website
I am using this adaptor:

Will this work with the stock kernel??

Probably not. I'm guessing at the very least you'd need to use the unsecured stock kernel.
I just got my microUSB to HDMI adapter from Monoprice and it works well. However, is it supposed to maintain current to the phone? I have it all plugged in and I get an orange light on the phone but I lost 10% battery power using it for 15 minutes. Doesn't seem right?
P.S. Monoprice customer service is excellent. I can't speak to the longevity of the products but the service is excellent.

I had the same issue with the same Monoprice MHL adapter, even when 'charging' the system with a 1A wall plug.

What is a 1A wall plug?
For the record, I am using the OEM plug connected to a microUSB cable I bought from Monoprice.
Uh oh. Did we get screwed?

I used an AC outlet 1 amp USB charging plug to power the system with a standard micro-USB cable.
People have observed problems with charging the Rezound through a car dock, so maybe it's related to that problem as well.
I tried charging using the Monoprice cable and it charged fine. If we were unsure before, I can say for sure now that it is the adapter. I don't know if it's the one sold by monoprice or, like you said, a bug in the system. Guess I can only watch 60 min. of video (tops and end up with a dead phone) or I'm out $7... kind of think I'm out the money... and no need for the cables I bought with it. Hope others read this.
The other Monoprice cables are fine. No beef with them.

I asked Monoprice about it. Here's what they said....

Hello Mr. Paul,
I understand that there may be an issue with your MHL adapter you had purchased. One thing to keep in mind is that our phones are really powerful now and draw a huge amount of power. So one thing to first consider is your power draw, secondly remember most androids can tell whether it’s connected to a computer usb port or AC power supply by checking if the data pins are shorted together. Since the data pins will be in use with the MHL adapter it will never register as an AC power supply and will not draw more than 500ma of power available to a computer usb port. This is not a limitation of the MHL adapter, but rather a design flaw in the implementation of MHL itself on the phone and perhaps design flaw is a little harsh but with the implementation of the MHL on the phone, not the adapter itself. Hopefully this clears up some things for you and if the adapter isn’t going to quite work out for you I can still issue an RMA for a return for you if you like I would just need an order number to get the process started.
Thank you
-----------
Again, good customer service. Unfortunate about the phone limitations.

Based on the information from tech support above, it sound like a hardware issue.

It is a hardware issue, the official HTC MHL adaptor does the exact same thing. (I have two of them)
~John
Yeah, I thought it might be something like that. People were able to fix the car dock charging issue by shorting the data pins, but obviously that won't work for the MHL adapter.
I ordered one from monoprice too, I'll test it when I get home from vacation.

I wonder if a Y adapter out of the phone to split the adapter and a charging cable would work? If there is such a thing for micro usb.
Don't think so. The phone won't draw the higher 'AC' charging current unless it sees that the data pins are shorted. If the data pins are shorted, you won't be able to get data out for the HDMI connection.
Basically, while it's nice to have only one port to keep things simple, a separate HDMI port and USB port for charging would have worked better in this case.
Well then I'm returning for a GNex.
If it's tethered via usb to a computer with an HDMI out to TV/receiver can you stream from the Rezound? And would the charge via usb be enough to keep it alive for a movie?
If not then I'm definitely dropping mhs. Connection problems and this issue... Bah.

Maybe depends on what else was drawing power on your phone. If you turned off everything else, maybe you would have enough charge to stream a movie. My battery was dropping pretty fast, but I didn't try to optimize by turning off mobile data, wireless, etc...

That would be exactly the same for the same reason, while connected to your wall charger the phone can receive 1000mA and will be in "AC" mode, when connected to your computer or another device which uses the data pins your phone will be in "USB" mode and can only receive 500mA, since your phone is capable of using as much as 1000mA this will not be enough to charge your phone if you are doing anything power intensive like say playing a movie etc. It will only supplement the battery power and keep it from draining so fast.
It should make it through a movie though. I have not tried mhl so I don't know what it draws from the phone. If you instal "battery monitor widget" from the market it will tell you what your draw is and will keep a history log of it with posts every 5 min, try playing a movie then go and check the log and see what it drains on average.
My phone easily makes it through a movie if I start with a fully charged battery, although it does steadily drain it.
As far as the nexus, if anything it is probably even worse with the bigger screen.

does the screen need to be on for MHL output to a monitor or TV?

On mine, the screen turns off as soon as it shows on the TV. If you unplug the connection, phone screen comes back on.

Are you using the phone to watch? Meaning is your screen on? It would seem that's the only way the screen size would matter. If you brought up the nexus due to my comment it was just a joke because of all the warring threads. I'm in love with the Rezound.
Hello everyone,
I was wondering if there is a way to increase the charge rate while connected to an MHL adapter.
I have a 2014 Civic Si that literally has an HDMI input for the head unit.
I bought an MHL adapter and it works very well other than a safety limitation that stops screen mirroring while driving, and the fact that even if I am just using it to get the best quality audio into my head unit with the screen turned off, the MHL adapter uses more current than it returns to the phone, resulting in battery loss.
I have the usb power connected to a 2 amp 12v charger that works fantastic when it is just connected with a regular micro usb cable so I know its not the charger.
I have found some evidence that there is a mod that can basically tell the phone that it is connected via AC to take more current.
Would be awesome if someone could provide this, or another solution to this problem. I imagine there are a lot of people like me out there who like to use MHL adapters but don't want their battery to die.
Thanks
Check the quality of the cord. If it's some cheapo one from like eBay or something that may be the problem.
I've found that some of my older degraded cords won't charge the phone while I'm using it.
Also if you roll/folded the cord up sometimes it can pinch it just right to not supply the right charging power.

To be clear it does show that it is charging (via USB) but its using more current than its getting thus end result is the drain.
It could very well be the cable - hence why I am asking if anyone can recommend a tried and tested solution of MHL + charge that actually charges it quickly.
Thanks,
BDS
