T-mobile mhl - HTC EVO 3D

First off is your phone supposed to discharge when using the the mhl adaptor ?
Is it only discharging because I'm not using HTC's mhl?
The video quality is pretty good and it seems to drain slower maybe but I get about 3 hours or so streaming live video off of own3d.tv from full. I think I'm draining 233ma last time I checked while streaming .
Oh also why do 3rd party chargers say from amazon charge poorly compared to the original? I need 3 and can't can't justify paying $75 to get 3 originals.
Thank you

As long as they put out 1A or 1000ma you should be fine. I have like 3 HTC chargers from prior phones and they work great. But I also have a backup charger rated at 750ma and it obviously charges at a slower rate.
With all that being said, I have heard various results using the MHL adapter. Some people report a minimal discharge, others report a fair battery discharge. Chad Goodman was working on a kernel that was supposed to support positive charging, while displaying MHL.

RLS9 of my old kernel provided charging while using MHL
it had issues though
not sure why - but
people either had
a) usb working 100%, charging normal, and mhl/hdmi caused reboots/lock ups
or
b) no usb, charging normal, and mhl/hdmi worked 100%, and charging while on MHL was ok
i am working on this as we speak for RLS2 of my new kernels - hoping it works for everyone, not just some

Won't charging over MHL work with a TV that has native MHL connections? Or will that work only with your kernel?

If it's a TV with native mhl, you should be fine, no adapter needed. You would just use the required cable only and receive a charge, plus display video.

How's it work?
Do you just plug it into the phone, to the TV? Or is there also Another cable needed to plug into the TV?
Thanx...

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.

Samsung MHL to HDMI Adapter not charging the battery

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?
Sent from my Galaxy S II (i777)
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.

Car adapters? (Powered via cigarette lighter port)

I have a one amp usb charger that cant seem to charge the Note while streaming audio over LTE, HSPA, or locally with beyond pod. With the screen off, i lose a percent every five to ten minutes while streaming audio through winamp, flash via the stocm browser, or beyondpod, and the note doesnt lose power while playing local media through beyondpod or winamp...but it doesnt charge either.
And when im charging via he wall adapter and im using the devjce it charges extremely slowly...this is a slow chargibg device, but really, cant i even charge it in the car while playing local audio? Can a usb device pull over a amp from a car charger? It was hard enough even finding a one amp adapter at brick and mortar stores. Are there more powerful adapters? Can the GNote pull more than an amp? Whats does the wall adapter pull?
What adapters are you guys using? Any reccomendations?

Nav, Pandora and a 5.3" HD screen running, probably just exceed the phone's recharge rate. I have found the very best recharging combo, while the phone is under load, to be the Moto charger and....wait for it....a cheap Hyperion 2600mah replacement battery on Amazon! I have no clue why.
The oem Samsung battery barely creeps upward while running nav and mp3's at the same time at about 5-10% an hour. Still beats my previous discharging.
But inadvertently, I found my backup Hyperion batt charges at a pretty quick pace with the exact same load. I haven't measured it yet, but it is at least twice as fast. Let the geniuses figure this one out, because it makes no sense to me.
My Samsung Galaxy Note™ is smarter than your Honor Student.
Using the moto charger, I started with a full battery, watched 70 minutes of streaming video in the Plex app this morning -- with a mix of 4G/LTE -- and unplugged with a full 100% charge at the end of that 70 minutes. Good stuff!
Just drove home today streaming Pandora in the car for thirty minutes with brightness on auto and Bluetooth audio to the car radio on my OEM Samsung genuine car dock. I was at 95% and when I got home I was 100.

The car charger? Or a moto wall charger?

battery only lasts 2 hours while using mhl adapter

using an mhl adapter to run an emulator on my tv. Also using a Bluetooth Wii controller at the same time. My batt only lasts 2 hours on a full charge. that just seems fast to me. the batt is charging while plugged in to the adapter but still dies. Is the mhl adapter using enough power to kill the batt in only 2 hours even while charging? seems a little useless to me if that is the case. I haven't tried watching a movie with it. Is that any better? anyone else experience the same?
Ate you pulling power from the tv? Or do you have a separate power adapter plugged in?

The reason why is that you have to have a mhl compatible tv. Mhl compatible tvs will charge your device while connected. They also let you use the tvs remote to control the phone while connected to mhl. This will explain a little better what I mean.

The difference bewteen MHL 2.0 and 1.0 is not at the power source. Your recommendation also have a power port. It also need power supply.
Samsung 2.0 smart adapter does require external power and is able to work with HDMI TVs(from wiki ).
I ordered this one from Amazon seller Eastwest Accessories (seems legit; many sellers sell counterfeits):
http://www.amazon.com/gp/product/B0080CXSOU/ref=oh_details_o02_s00_i01?ie=UTF8&psc=1
The port is longer than typical microUSB and must be inserted further into the phone. It needed power to work for me and power needed to be connected to it before inserting into the phone.
I also ordered a Chrome Cast and I am considering ordering the AllShare Wireless Receiver from Samsung.com using the half-off code they send for registering my phone.

I am fully aware of differences, its not the only one, but is most certainly a distinctive practical difference. The one I recommended does not Need a power supply other than the phone (compatible ones such as the N3), but does have it there incase you want to charge the phone while using it. It provides 300mah when plugged in.

This is the way to go. The one in the OP looks like there's too many components needed for it to work. This one from Amazon does not need a power supply or an 11-pin adapter. Just plug and play. I just got mine a couple of days ago and it's perfect!

You mean you weren't able to charge simultaneously? Were you using the stock 2-amp Samsung charger?
No. I don't like using MHL and charging the phone at the same time. It can't be good to battery, with all the heat and heavily discharging while charging.
MHL 1.0 without charging (and lowest brightness):
- stock video player: 20 minutes, 6% drain
- youtube, nba app, coursera app with wi-fi on: 20 minutes, 8% drain
- MX player: 20 minutes, 10% drain
What I would like to know is if MHL 2.0 adaptor (without charging) drains less battery.

If the battery controller and ppwer management are smart enough it should switch to external power once the battery is charged. Heat will also drop because the battery is neither charging nor discharging.
I'd be more concerned with the extra cycling the battery is going through without charging. Obviously, they originally expected you to charge while outputting video, so I trust the engineers who would know better.
Anyway, what MHL1.0 dongles even work without charging? It seems you've been using one.
I'm using MHL adapter from Samsung (official accessory for S3) and it works. Only adapter + HDMI cable, no power, no USB cable required. but FPS are way worse. it's only good for watching movies and not playing games.
Ok how are you guys getting this to work? I've tried it with an MHL 2 adapter (for S3, S4, Note 2 and higher) and I get nothing. I had one of the expensive MHL1 adapters with the 5 to 11 pin adapter that "kinda" worked, but the adapter made it a flaky connection, so I returned and went to the MHL 2 - 11 Pin only to HDMI - nothing...zip, zero, nada. Have tried netflix, MX, etc.
Does screen mirroring or airplane mode need to be on or something?
Baffled
Should be plug n pray, but try mirroring if that is an option

I believe I've got the same one hurdlejade has but mine didn't work unless I plugged power into the MHL adapter BEFORE inserting it into my Note 3 even though it shouldn't have needed power at all.
Does Vic Tsing MHL converter work with Receivers?
For those who have the Vic Tsing MHL converter from Amazon has anyone tested plugging this into a Receiver HDMI/MHL port. I have the genuine Samsung and that only works if you plug it into a TV.
Also for the discussion about charging. If you are using MHL output and have a power adapter connected you are not charging your battery. All of the output from the charger is being used to power the phone and the converter. This means less drain on the battery and it should run cooler. The phone itself will draw the same current whether it's coming from the battery or the adapter so it will run as hot either way. From memory mine ends up draining about 1% every 15min using an adapter and the MHL 2.0 converter from Samsung.

Wait. So even the HDMI dock with USB hub that was supposed to turn the Note II into a desktop PC had less flexibility than a battery powered notebook?! At least a laptop can be plugged in to charge during use! If the docks do it but the MHL adapters don't, it sounds like a horribke tactic for selling more expensive docks.
