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.

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:

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.
Has anyone noticed that the tablet will drain the battery under use even on the charger?
I was quite surprised by this. Light use yields a charge but native gaming (not streaming) produces a power deficit. Something such as the Face demo will drain the battery in under a hour even on charge. Games such as Half Life 2 I have noticed will yield 5-6 hours of use from 100% to dead.
I have ordered a good 18 awg charge cable and solid 4.8 amp plug I am going to test with it. I have a usb voltage/amp meter coming as well to see what it is pulling during charge and use.
To this extent, I wish they had included an actual charge port to negate the over draw.
This happens to me but only if I'm plugged in via PC usb slot, wall charger is the only thing that seems to not drain battery while plugged in for me.

Noticed this already myself. It's kind of depressing how slowly this thing charges and it's REALLY bad if you can't even positively charge while gaming!

That way those of us affected can get our chargers rma'd.

No. I'm an idiot anyway. Playing a game with shadowplay is going to draw more battery, der!
Not happy to know this tablet will be useless after the battery reaches a certain cycle count. I won't even be able to use it as a wall tethered device via the charger. With it depleting the battery constantly, the charge cycles are going to add up quick.
Im on v1.1 and for me just streaming netflix in console mode hooked up to my tv using the included charger and cable and starting from a full charge will cause significant battery drain. I almost made it through streaming season 1 of SOA and it died in the middle of the last episode. And it doesnt seem to charge in console mode even when its just idleing. I have to pull the HDMI cable to get it to charge back up. The stock charger is putting out 5.2 volts and 2.1 amps I wonder how much power you could push through the micro USB port before it fries something. Im going to try ordering a 3 amp charger off amazon and see if it still does that. I found a 5 amp one but I dont want to mess anything up. I couldn't see gaming on this thing for very long like this witch is pretty disappointing. If I try to play trine in console mode it kills the battery much quicker and it gets pretty warm. I was hoping to use this thing more like a android TV device than a tablet and just leave it hooked up to my TV streaming video most of the time. I bought the shield controller and a Bluetooth keyboard for it and it works out really well except for the battery drain. Hopefully the new charger will solve this.
Edit:
After doing a bit of research into the "usb fast chargers" it turns out they are all fakes. Some ads are just a little confusing because they do put out more power but its just spread across multiple ports while others just tell you lies to get you to buy their product. Truth is they all charge at either 1 or 2.1 amps per usb port max. The only real fast charger is for the oppo find 7a witch has 7 pins in its usb port. So this might be kinda hopeless.

This is old news. If the current would be higher, the plug wouldn't be safe. I don't understand how Nvidia could be so "foolish" and forget a seperate charging solution, especially considering their computer GPUs can take up to 2x8 Pin 12V.
Just another reason why I will wait until there are more news about the second batch and the next Nexus.

It's not all that bad I'm still really satisfied ..After about an hour and a half of playing it only drops from 100% to 94 percent while connected to charger...and that's only on a heavy game like DDE..it does look great!
Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?
My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.
The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

If i were you, i'll check with another charger doing normal stuff, if you still get negative charger maybe it could be your battery itself.

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.
First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.
I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.
Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

Get in touch with the retailer you got it from and ask for them to provide you with a proper charger, as a compensation

A bit hard to do since i got it from amazon.com when i was in the US (back in EU now) and there's no point in returning the tablet just for a semi faulty charger.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try
Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.
I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.
Hello guys,
I have a 1~2 yr old 5V 1A charger that I would like to use to charge my Pixel (non XL) overnight. The included 3A charger heats up the phone a lot, and I really don't need the speed at night.
The thing is that this charger comes with a micro usb (charge only, no data) cable that I'd like to use. For this of course, I am using a TechMatte micro usb to Usb C adapter that I bought a few months ago.
Is there any problem with this? Will the adapter cause the phone to draw power differently, or to behave differently when it comes to stopping the charge once it reaches 100%?
Sorry if this is an absurd question, I just don't want anything bad to happen to my brand new Pixel.
Thank you in advance
I've been using my existing micro USB cables with a converter head from Anker without any issues for more than a month now!
I think as long as the adapter have the 56kΩ resistor you should be safe, but really I highly doubt there are any benefits to slow charging (even if fast charging is making the phone warmer).

I'm with you on this one generally, I personally don't hang on to a phone for too long before upgrading so longevity only needs to be 1-2 years. For someone looking to get the absolute most out of a device, I could see why heat would be a concern. More heat typically translates to more wear and tear of the innards. Even if it's by a negligible amount... lol
Also, Samsung might have people paranoid that their phones are going to blow up... just sayin :laugh:
