Hello guys,
Lately I have been using the MHL/HDMI cable for gaming on my Galaxy nexus to play Modern combat 3. Since i'v tethered my dual shock controller through bluetooth, Wifi is on for online playing, and the screen is on while playing, always run out of juice!! Even though my phone is plugged to the charger.
so i have been wondering if any of you guys could help me put my screen off while plugged into MHL/HDMI. Or help me under volt. thank you
Are you sure your using the correct charger?
Try a 10watt USB iPad charger.
am using the apple 10W USB Power adapter. input: 100-240v ~0.45A.... 50-60Hz Output: 5.1V 2.1A
the white block one
I think the nexus is limited to 1A. Not sure if the limit is changed when using mhl. Also, heat is a factor. It might be possible to get longer play times if you have air flow all around your nexus to keep it cooler. Meaning elevate it without a cover on. And maybe a fan blowing on it.

When you charge go to phone status in the settings does it say charging Ac or charging usb ? if it says charging usb there's your problem.

MHL is limited to 500ma per spec.

Q. 4
Pogo pin charging seems like our only hope.
Came here to ask the same question as no matter what adapter I used it showed charging USB which for gaming isn't enough by a long shot. Good to know i'm not the only one.
Is there a way to get the kernel to ignore the type of connection and draw as much power as is possible? Similar to how many of the tablet kernels were modded to allow charging over USB and not just the adapter that was packaged with the device.

Has anyone tried a charge only cable? These are the cables which have a short across the data pins. I know it's a long shot since the AC charger should cross the same data pair.
I hope there is some XDA magic that can be applied to draw more current. I have a feeling it will require a hardware tweak of the MHL adapter and driver level hacking of the silicon image chip.
I have tried a few different AC adapters including the blackberry, HTC, and a random LG charger and they all showed as charging as USB and not AC. I would imagine it is in all MHL adapters and/or the phone.
Hi bringing one charger around would be much convenient. Can i use ipad charger, with 2A output to charge galaxy note?
Tq.
Yes. I've charged mine with it many times.
Hey thanks...
Apple out of norms
Hi
Using a standard USB cable will get you a slow charge, even if the Ipad charger is very powerfull. This is because apple doesn't follow the rules.
Charging your Note may take 6 hours then.
To get fast charge, you need to modify your cable or charger, as stated in this thread : http://forum.xda-developers.com/showthread.php?t=1497864&page=2

The increased charge in this mod seems to work for charging via usb port, power from a pc. Charge from main ac lead still higher.
So does charging my Note with an ipad adapter + Note usb cable help increase charge since the ipad adapter has an 2A output??
I'll try to make it clear.
Using a common adapter or any pc USB II or ANY apple adapter will give give you a slow charge with a standard USB to micro-USB 4 wire cable.
This is simply because they can't usually deliver more than 0.5A. For apple, they have a specific standard out of the USB norm.
To go into fast charge mode, the gnote scans pin 2 and 3 of the USB link. If they are short circuited, the gnote tries to go into fast charge mode, and draws up to 1A.
The short circuit of data pins (2 and 3) is specified in the USB norm to state "this adapter can provide 1A"
Some adapters, such as the Samsung one I got with my gnote, already have these pin short circuited inside them and make your phone go into fast charge mode.
If you have an adapter able to supply 1A or more, such as your Ipad's, the simplest way to fast charge your gnote is to have a modified cable. No risk to harm your phone nor your adapter if you respect the wiring.

what i want to know is:
if the ipad charger is 2A, will the phone draw all that 2A or just 1A?
im asking because if it designed to work with a 1A charger - is the draw capped at 1A?
Hi
The draw of any phone is limited to its maximum power consumption ie phone consumption + battery charging.
I believe this draw is limited to 1A within the gnote.
Having a 2A charger only means it can provide up to 2A. It's the "pipe" size, in a way.
If there were a way to increase the gnote draw to more than 1A, by example in order to charge the battery faster while using the GPS, this could be :
Either telling the gnote, using a resistor on the 5th pin of the micro-USB plug.
Or using a specific app.
(or both)
I'm not aware of this possibility at the moment.

Jabab, thanks for ur valuable expert info. I've notice that charging my gnote with the ipad charger isnt much faster. But charging iphone with ipad charger does gives a great boost. What makes it possible with iphone?
Apple uses a not so different system to tell the iphone or the Ipad that it is connected to a powerful charger: the data pins are connected to the power pins through a ladder of resistances.
I see one main advantage to this: apple could change the resistances values inside the charger to indicate to the device if it is an 1A, 2A or any other current charger.
The main drawback is that this system is compatible with nothing but... Apple devices. This why you get a slow 0.5A charge with a 2A capable Ipad charger.

I believe though that you need a 1A (1000mA) at least charger to do the indicated mod on the charger for use with a Galaxy Note.

I just got the Galaxy S 4 the other day. It didn't come with a USB cable so I used an old HTC micro-USB cable. Even though the cable worked with my HTC phone, it doesn't exactly work with my Galaxy S 4. I have to move the cable in a certain way to get it to charge or connect, otherwise it doesn't work.
I was able to charge my phone using a micro-USB charger for a bluetooth device (trickle charge, took 12 hours to charge), but obviously this isn't ideal. So is there something wrong with my phone, or just my cable? And what type of micro-USB cable should I get that might work?
It doesnt come with usb ??
Charger works as USB too.
Htc cable doesnt work on samsung phone. Motorola does.

It isn't your usb cable. You need a charge that output 2A at 5V to charge the S4 at decent speed. Computer's USB or typical 5V USB chargers will not do.
Just FYI when I use an older usb cable other than the samsung one, my charging time increases. So using the right USB cable matters. I use an app called Galaxy Charging Current Lite to determine my charging amp with other cables and other wall and car chargers. Very useful app. When using the samsung usb cable with the wall adapter I get 1900 and I can see the battery percentage go up faster. Using an older usb cable with the samsung wall adapter I get about 460 and battery percent goes up slowly. Try the app out and see what you get.
First thing I'd be doing is complain to T-mobile or Samsung. Both GS4s I've received (one on launch, one from insurance) came with the USB cable and charger ready to go.
Next, you need 2A @ 5V, but ya need the right power brick to supply that.
and most likely using older/newer/non-Sammy cables and charge time increasing is because the cables use a smaller gauge wire (like 28 or 30 AWG IIRC) rather than say, 24 or 20 AWG (keep in mind that the smaller the number the bigger the conductor, and larger numbers have smaller conductors). Even with the right power brick, the USB cord still matters; I remember on my Nexus 7 that unless you used its cable charging was either sluggish or non-existant. (FYI the Nexus 7 cable should work with the GS4, I use it for file transfers o my computer and when I did all my rooting.)
also I personally use the battery monitor widget on my Nexus 7 to monitor voltage/current input/output. I may consider putting it on my GS4.
Specs aren't listed and I've already wasted money on 2 car chargers that don't charge my note 2, despite being touted to do so.

Well..they charge him, but in slow mode. Connect your phone and go to Settings->Battery..and you will see one of this "Charging (USB)" or "Charging (AC)". If it says USB, then you only have 500 mA, and AC gives you max from your charger. Original charger for Note 2 is 2A. So, I doubt that any car charger will give you that amount of electric charge. It can help, but it is a really slow process.

Does your cigarettlighter-outlet in your car working?
I'm using a SonyEricsson MicroUSB car charger bought and used with the SE Xperia X10 Mini in 2010. It does easily charge the Note1 while using Google Navigate+GPS and the Spotify (Via Bluetooth with the car stereo).
this subforum for N7000, I suppose?

I purchased a splitter from Amazon that came with 2 cigarette and 2 USB connections. I used the cable that came with my N7000 originally and plugged that in and it works fine. You can go on eBay and search for 2ah USB cigarette charger and just use the cable that came with the note to charge it up.
I wouldn't buy any longer cables as it seems to slow down the charging process by quite a bit.

Just wanted to know what are specs for the charger/cable. I can get tons of aftermarket chargers for my ip4 at a buck or two at the most from asian sellers from asia. am I right that I simply need a 2a charger, with a mini usb cable at the end? just looking into getting extra for when they decide to release it to the public.

Anyone tried to trace pinout yet? IIRC, I read somewhere 2 of the pins in the cable were shorted, signaling to the OP that it was to take quick charge. I'll try to find that. The same article / post discussed temp sensor limiting amount of charge since the OP would get hot. Not as quick as true fast charge, but faster than standard.

I have a question. If you use the OPO charger, but plug a usb extender into it(and the OPO cable goes into a usb female at the end of the extender cable), does does having that non-OPO cable in the chain slow things down? Mine does seem to charge slow, but I've honestly never connected the OPO cable directly from the charger to the phone to compare. I honestly don't understand how anyone could use it like that (or any other cable coming with a phone). Not even long enough to stretch from an outlet to a table top if the outlet is right next to the table. My Dell Venue 8 Pro cable is amazing(ly ridiculous). It's maybe a foot long. I guess they expect us to charge our devices on the floor? With the DV8P case the cable would barely even reach the floor!
i can confirm that using the OPO wall charger with a 3rd party usb cable does result in a slower charge time. I tried 2 different cables-- both were of different gauges and lengths-- both resulted in different charge times and were all at least 2-3x slower then the OPO cable. anybody with knowledge as to what kind of cable OPO is using and where we can buy longer versions?

I can also confirm slower charging using the stock charger with aftermarket cable. But most of my cables are cheaper, is it possible that the gauge of the wire inside the cable is higher on opo cable? Allowing more amps through?
Also, @effluent , if using an aftermarket cable slows things down, I'm assuming putting an extension in the middle will have very similar negative impacts.

You want a charger cable that won't fail.... Stop buying them online. I've bought them everywhere online and they just can't compete with the usb/charger cable from tmobile.... Maybe be the same for other service providers. Plus you get 30 days to refund or exchange.... So you know after a month if it's worth it which it is.... Those teeth won't sit down and ruin the quality of the charge like 90 percent of the cables online.

You just have to find the right cable. I went through this same thing with my galaxy s5. I got the application "galaxy charging current" and compared the milliamps of all my cables. Some would only do 4-500 ma. Some would do 1800ma. It just depends on the cable. I'm using the cable I got with a ps4 right now, and it will do 1800, and it's 4 feet long.

Try a fast-charge cable, it has the correct pinout (shorted pins) for fast charging.

And you can't overcharge, it's the phone that demands the current, not the charger that pushes the current through the phone. The phone's charging circuit protects the phone for overcharging and handshakes the right charging current with the connected charger. Charging Android is quiet a complex thing...
