I first bought a monoprice MHL adapter when they became available at around $11. I was very happy with it, but started looking for another to throw in the car for when I visited my girlfriend, or otherwise wanted to share video on the go. So I went on EBAY and bought a $6 cheapie adapter - that surprisingly worked at least as well. Later, I decided to buy a bluetooth joystick for gaming and bought a kit which included yet another MHL adapter, this one with an HDMI cable built in which made it convenient. This one cost roughly $12 in the kit.
You'd think I'd be done buying MHL adapters, but a thread which I now believe had false data - cited that the official Samsung MHL adapter output 60 FPS from the evo 3D. When I noted that all of my adapters output at 30 FPS - and the thread maker did not respond, I decided that it might be worth buying the Samsung Adapter as a test. To be sure - I bought the adapter directly from Amazon (not a vendor) at a premium price of $25.
I will note that to date I've seen no difference in Video Quality. I'll follow up this thread with a post reviewing video and gaming - but for now, all 4 adapters report 30 FPS from a stock EVO 3D, and I can see no difference in video quality. Where they do differ is in charge rate, and compatibility with the HTC dock - because some have bulkier micro USB plugs than the others.
One note - my original EVO 3D gradually lost HDMI output. Though presumably the output was digital, I got snow which varied by jiggling the port - and on some TV's I could get no output or strange colors and lines. I figured the port was shot and got a refurb insurance replacement - that fixed the problem. Since then - I've tried to use the HTC dock wherever possible to prevent further damage to my USB port. The HTC dock works great - with push button HDMI output and costs $15 at Radio Shack. The drawback is that you can use NO cases.
The following charging tests were done with Battery Monitor Widget. Having tested A LOT of battery monitors from the market - this is the only one that consistently works well. To set up this test - I connected each adapter to the dock (where possible) and only left wifi, phone and 4G on. All used the same USB charger (2.1A - though we max out at 1) and since a portion of the charge goes to the adapter, I wanted to see how much actually went to charge the phone. I didn't actively run programs - I stayed on Battery Monitor Widget's screen and monitored charge rates for about a half hour each. I can tell you that charge rates playing videos have been pretty consistent with the results - some MHL adapters drain the phone playing videos, others don't.
First - the monoprice adapter ($11):
http://www.monoprice.com/products/p...=10833&cs_id=1083314&p_id=8805&seq=1&format=2
This one works well - though it is NOT compatible with the HTC dock.
The best charge rate I got in a half hour: +179 MA
This result is better than on any of my previous tests, I'm a little surprised the result was so good for the monoprice. Using movies on my card through dice player - I believe I could play for at least 10 hours straight without running out of phone battery (stock). There's a little drain, though streaming would burn battery much faster.
Next - the EBAY adapter ($6):
http://www.ebay.com/itm/Micro-USB-M...&otn=3&po=LVI&ps=63&clkid=7852517687946872680
It appears the price has gone up since I bought it - but this one works great and DOES fit the HTC dock perfectly well.
The Best Charge Rate was +209 MA
Which is great. I was first shocked to play movies on it - and see that my phone got fully charged.
Next - The Phonejoy Video Game adapter ($12.90):
http://www.phonejoy.us/shop/mhl-male-cable-microusb-to-hdmi/#tab-description
This one is a tight fit with the HTC dock, it makes me nervous to use it long term this way - because I think the dock port or the cable will fail.
However - it includes a full HDMI port (no cable needed) -and is designed such that the long micro USB cable puts little strain on your phone while gaming. It's a good design, but the only drawback is that at 3FT the cable is really too short to game on a big TV.
The best charge rate in a half hour: -9 MA
You read that right. It drains the phone while using it - I couldn't get it to charge for some reason. A definite negative.
Finally - the Samsung adapter ($25):
http://www.amazon.com/Samsung-MHL-H...UDKK/ref=sr_1_1?ie=UTF8&qid=1334923643&sr=8-1
It fits the HTC dock. It's certainly the prettiest, it's smaller than the others, glossy and feels expensive. Which at double the price (at least) - it is. But who buys electronics for the looks? Not I.
The best charge rate in a half hour: 219 MA
So the Samsung did charge the best overall. But are the extra 10 MA worth paying $25 instead of my $6 eBAY special? I don't think so.
I'll try to be detailed with a post later in the weekend, but right now - I see no video output difference using the EVO 3D. If any of these adapters has 60FPS capability - it's not with a stock device. I've been playing 720P videos and 1080P videos at 30FPS using Diceplayer - and noticed no quality differences. I've tested 3D videos on almost all of them - and they work great on my passive 3D TV.
In short - right now, my $6 EBAY special is proving to be the best bang for the buck and unless I see better video quality in gaming or other content this weekend, the Amazon adapter is probably going back. It's possible that other adapters have lower quality - but the 4 above that I've personally tested seem to work equally well at video output, with the only differences being fit and charge rate.
Due to the lack of replies, I thought no one was interested in this thread, so I didn't return to it. I only just realized that some users thanked me for it.
I just spent about 3 hours going back and forth between the Samsung MHL adapter and the EBAY cheapie. I'd watch 2 minutes of 720P MKV on one, then repeat the process with the other adapter. I then played a level or portion of a level on Shadowgun and then switch cables.
The end result is that I still don't see a reason to pay extra for the Samsung adapter. Every time I thought I saw a defect with one cable, I'd swap cables and catch the same video defect or game artifact. I was watching 3 FT away from a 1080P 32" LED - and could spot no definite differences after a few hours of testing.
That's proof enough for me - though it's possible with another device that we might see a difference in these adapters, I see none with a stock EVO 3D. I'm going to be returning the Samsung MHL adapter to Amazon.
Thanks for the post! ...on another note, Maybe you should try a video player that utilizes hardware acceleration? Mx player?? Maybe the player is capping your fps? Just a guess

Perhaps this has been asked before, but I've been looking at some cheapies on eBay. The ones that plug into the mhl port, have an HDMI adapter, and an additional adapter to plug your charger into. Will this charge the phone while it outputs to the TV? If not, what's the best solution to output and charge at the same time?

Umm, I'm already using Mx Player. But on our phones it's not as good as Diceplayer. My FPS is not being capped by the software, at all times - connected to my TV it reports 30FPS. That's whether you're on the main screen or actively playing a video.

Yes, it'll charge - but like I pointed out in my extensive review, not all adapters charge at the same rate. If you get an adapter that I didn't review - it'll be a matter of luck how fast it charges.
Also - if you're running intensive software, like streaming video - you may not charge at all, and may instead drain the device.
I'm using the stock Samsung MHL adapter, and I get a negative battery drain every time I output video via HDMI using MX Player... pretty disappointing. Using the stock power adapter. Have you been using an aftermarket power adapter that has a higher output to get the positive charge?

That's really odd. Even if I used a more powerful charger, our phones max out at charging with a 1A rate. In general, I can confirm that the stock charger would give you the same results as above.
The only way I can explain your poor charging, would be if you are streaming via WiFi, your phone is trying failed data connections repeatedly, or perhaps most likely - you bought a bootleg Samsung MHL adapter.

Thank you for this info. I took your advice and bought two from Ebay for under $5 bucks each and no problems with playback or charging. Though i must confess I don't know how long it takes to completely charge the phone. The USB charger plus in the side of the adapter.
Just a fyi...
The length and quality of the cable between the charger and your phone will dramatically change the charge rate.
The longer the cable the less charge rate
The thinner the wires the less charge rate.
And as you can imagine a combination of length and crapy wire =
A lot of the cables on eBay are terrible as they are made as cheap as possible.
I have found that the coiled (spring looking) ones are almost always good as you can't make a decent 'coil' with crapy wire.
Hope this helps.

Just a question to those that tried: How is gaming with such a Cable? Can the Evo 3D handle games on the big screen, or is it a sluggish mess? Also, how well do them cables cope when you put the phone under the strain of gaming? It runs through my battery pretty quickly when playing Dead Trigger or the like (and pretty much doesn't charge with the charger connected); how well do them MHL-Cables do at keeping the phone running? 219mA in 30 minutes seems rather poor.

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.

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.
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 received this from Amazon yesterday ...

This is a passive cable, different from the MHL->HDMI adapters that Samsung sells in that it has no electronics and as such requires connection to an MHL certified input such as those found on the latest TVs and receivers. It also has a 5 pin micro-usb 2.0 connector so requires the 11->5 pin adapter to be used with the N3.
The picture came up as soon as I plugged it in at 1080p/30Hz. The 30Hz limitation is from the Yamaha RX-A1030 I was testing with which supports 1080i/60 or 1080p/30 but not 1080p/60 through MHL. I'm also seeing around 300mA charging current with the screen on which means around 900mA total coming back from the MHL input on the receiver.
All of the videos I played went without a hitch (even those with Cinavia protection), with full 5.1 surround sound. In about 15mins of testing I drained about 3% from the battery so it's losing ground but slow enough that you could get through several long movies before needing to reconnect the N3 to a charger. The cable is a little stiffer and thicker than I'd like, comparable to high quality USB 3.0 cables but at ten feet long it's pretty reasonable given the bandwidth it's delivering (and the charging current).
Would just like to share with everyone a good quality and very useful tool I've recently got hold of.
I've had and used a few different Choetech products and the quality is always amazing, the presentation when the products are delivered gives them a premium feel even though they are quite a reasonable priced product. I would say the quality rivals that of anker and aukey.
The cable itself works with any USB A charger and any device with a micro USB port, a USB A-C cable is also available for those who have a USB C device. The cable is just plug and play, once u connect to a charger the display lights up and when the device is connected you get readings.
I tried this cable with a few different devices and chargers but I found it especially useful for testing how good the fast charge chargers we're when using a galaxy s7, even though the s7 shows fast charging I found different chargers would give me more current at 9v.
For anyone interested in a good quality charging cable that is also interested in seeing just how good there chargers are this is a perfect product. I've also used the cable to transfer data to and from my phone as I wondered if this would be effected and I'm happy to say it wasn't.
For anyone in the UK interested I've got discount codes that are valid till the 31st of jan that make these or the USB C version £6 each. Hope someone finds these useful.
Code 5M9WY7AX

They do now!~
I just ordered and received one of these things to finally have one for monitoring. This thing was great and has actually taught me a few things i didn't already know. For one, I didn't realize that fast charging stopped the second I turned on the screen of the phone! That's right these phones jump back to regular 5volt charging when the screen is on. The second the screen goes off it's back to 9 volts.. Good to know when you are trying to maximize the charge rate. Anyways.. i digress.
So far this puppy has been accurate. I have used it on my S7 Edge as well as my htc 10 with a choetech micro to C adaptor. I am able to monitor and track the various stages of quick charging without disturbing the phone's charging. This cable seems to be well made and doesn't seem to be cheap. The display is solid and bright.
I attached some extra pics showing the display toggling between charging current and voltage. If you are looking for a simple USB current monitor with some forward capability I would recommend taking a look at this one.
For $16.99 shipped on Amazon Prime it's not a bad deal
