I know this is mostly common knowledge but I still see many questions regarding this come up, so instead of explaining this over and over I can now link to this and flame away.
anyway...
When you charge your phone using an original HTC wall charger you phone gets all the power it needs to run itself and charge (up to 1000ma).
When you charge from any (most) other devices (this includes car chargers,non HTC wall chargers or any USB port) your phone will draw up to 500ma (the USB standard) REGARDLESS of the devices output.
The reason why the phone only draws 500ma on USB is so it does not damage any equipment by drawing more power than it can output safely (by design anything with a USB port can safely output 500ma).
The trouble is pretty much all equipment can safely output more than the USB standard of 500ma and safely charge your phone at full speed.
The phone distinguishes between an original HTC charger and other devices by whether or not the data wires are shorted (connected to each other).
How to do the charger mod.
Disclaimer: I take no responsibility for anything that may happen as a result of doing this, by following these instructions you will be pushing any device you charge your phone from beyond the USB specifications, results of this may be, but not limited to your motherboard bursting into flames, you car exploding, the inventor/s of USB knocking on your door and slapping you in the face, but most probably faster charging and not a lot else.
Get yourself a short USB extender wire, male at one end, female at the other.
Cut the wire in half.
Connect the red and black wires up as they were before (or don't cut them in step 1).
On the Female side of the wire connect the green and white wires together.
On the Male side of the wire simply leave the green and white wires connected to nothing.
Insulate the ends of all of the wires with insulating tape.
Tie a knot in the wire so if the wire is pulled the knot is pulled and not the connection you made, it doesn't look pretty but the wire will last a lifetime this way.
All done, now use this wire in between your desire and whatever you want to charge from and get a full speed charge. You will lose data connectivity when using this wire.
There are other ways of doing this, for example.
Soldering together the data pins (middle 2) on the device you wish to charge from. Don't do this on your laptop...this method is intended for car chargers, wall plugs, and external USB battery packs.
Soldering together a male and female USB port and plug directly with no wire in between, this can look really good if you know what your doing.
Great guide! Just a quick question I have a 3rd party USB cable but an official htc wall plug. Will my desire still get 1000mA? Or will it only get 500 because of the 3rd party charger?

The original charger shorts the data pins so it doesn't matter what cable you use.
Hi,
just wanted to say thank you for the idea. For me this is really usefull in some situations at work, where I have no access to a socket, but a pc.
It charges not as fast as the AC charger, but MUCH faster, than the usual 500mah USB method.
And so does it look like:

And next time, use your brain first, please.
Do you have an idea why the HTC Desire does limit the current to 500mA if it's not connected to a dedicated charger which shorts the two data pins? Ever thought about it? Ever?
Umm... yes. But please feel free to enlight me.

So in other words:
Any laptop or computer can output max. 500mA by USB specifications.
So this means:
You can have luck and your computer doesn't get damaged if more current gets requested, it just limits the current to something around 500mA.
You can have luck and your computer just shuts down the USB port and Windows reports you that a malfunction device got connected.
You can have bad luck, most often the case, especially on cheap notebooks, netbooks, computers, a fuse will prevent bigger damage and the USB port remains dead until the rest of it's computer live.
So the limit got wisely chosen. So if you want to use your USB ports in the future, too, then only use this 'trick' on wall adapters which support an output current equal or larger than 1A (1000mA), or use it only in combination with USB ports which support that high currents (most often advertised as being able to charge the Apple IPad), most often found on external USB hubs.

I was that 'unfriendly' because other people will do the same, because person xy said that it works. Then they fry their mainboard or notebook and complain.
I also don't understand why anyone risks damaging intentionally its computer or parts of it, especially if there's absolutely no need for it, e.g. just let it charge in USB mode, or take a small charger with you, or at least use two USB ports to separate the load.
But well, maybe some people don't have to take care of their computer.
This is an interesting thread. I have a Pebble charger and it literally takes four hours to charge my 1400mAh from ~0% to 100%, now my question is, will this damage my Pebble charger shorting the two wires to draw a greater current from the unit?
Overheating, melting and explosions are something I am looking to avoid.
I have yet to find a device that has been damaged doing this. I have personally tried this on a ps3, Xbox wii, 4 laptops 2 desktops, car radio,car charger and a sky+ box.

Did you try this? I too have a Pebble and would be interested to know if I have just 30 minutes to plug it in, can I charge quicker.
Also, did the guys PC blow up? He said he would come back!?!? Maybe it did and he's in hospital still Dangerous things USB ports...
thanks for this ! I go to try this
MM i have an interesting one (which i still dont get)
i have a pebble charger
with OEM HTC Micro USB charger cable
and Pebble charger
plug phone into OEM micro USB charger to phone (phone says Power AC) yeh thats right
OEM Micro USB to computer (chargin USB)
So far so good
Pebble charger OEM USB to phone (chargin USB)
Pebble Cable charger to phone ( Power AC)
why are the OEM and Pebble charger cables different?
Sorry if i am posting in the wrong area but the topics seem pretty similar to me =P
to put my 2pence in, i've just done this but slightly different than the OP method..
i bought the belkin car charger, gives 1amp, but is detected as 'USB', not 'AC' charging mode, so my phone only charges upto 500ma which isnt enough (in reality it doesnt charge when i have GPS & max screen brightness).
instead of modding a USB cable (unable to use for data) or buying extra kit (money/ordering/going out) i pulled a strand of wire from a spare mains cable i had, threaded it through the 2 center pins on the belkin charger and then twisted the wire together.
USB cable is slightly tighter in the socket now, but still removable and keeps everything nice and tidy.... and more to the point; cheap!
poor shown from belkin; 'USB charger' mode in a car! like it would ever have data connection to the 12v socket.
hope that helps someone!
USB cable to quick-charge an HTC smartphone
Check http://winhlp.com/node/855 for some more details and photos of a USB cable modification.
Does this mod change the detection of car mode
Hi,
I have just started flashing a couple of roms and noticed that when using my desire with my car charger (1amp rated) it does not charge when doing navigation. looking on battery widget I get a max 289mw on car charge and it is showing as a USB charge. Flashed back to stock and now the car charger shows up as ac connected rather than USB. This does solve the discharging on navigation issue but I would like to run Gingerbread.
my question is...
Will this mod stop the Desire detecting and automatically entering car mode when it is plugged in? Anyone done it to their car charger?
Ta
Yes
The cable modification (shorting the data lines 2 and 3, instructions at http://winhlp.com/node/855 ) will switch any HTC smartphone into AC charging mode.
But I am totally stumped as to why you can achieve AC charging mode without this mod. I know of no other way the HTC phone could detect a car USB charger. I'm tempted to ask you to repeat the test.
If anybody here has any idea, please respond. To the best of my knowledge no USB device is allowed to pull more than 0.5 A from USB power, lest the power source switch off according to the USB specification. The only exception is that the device gets positive information that it is connected to a charger that can deliver a higher current, and for HTC devices that is signalled by a shortcut between the two data lines.
Thank you. I would rather not check again I did look for a while. Reverted back to stock for now.
It is a Huawei curly lead car charger with a 1a rating. The strangest thing is that with my stock Vodafone rom it detects as AC power on battery widget but on both leedroid and RCMix it shows up as a USB charge and I get the power issue. On all three roms it detects car mode correctly (Which is good!).
I was just wondering if the mod would also break the car mode detection?
I can't find anything on how car mode is detected!
Hi guys, I have this VERY STRANGE issue with my Gum Pro and my SGSII. If you don't know what I'm talking about the Gum Pro is basically a larger battery (4400 mAh) that you can use on the go to charge the battery of your device as it was charging with its own charger.
Ok..I always used it with any device I had. Cellphone, MP3 or whatever else neede to be charged when I wasn't home or hadn't any plug available....
Today I got the SGSII in exchange for my HTC Sensation and a while ago I neede to charge it while moving from one room to the other, so I connected it to the Gum Pro and.......nothing....I tried to unplug it and re-plug it in...nothing....I tried to plug it to its charger and it's working fine....I tried to plug it to my PC and again it's charging just fine....I also tried the Gum Pro with an old HTC I have for emergency and even the Gum Pro it's working fine...but if I connect the SGSII to it nothing happens: like it doesn't exist!!
Can anybody tell me WTF is happening??? I don't get it: both the devices work fine, but the can't get along....
Any electrical engineer or technician can give me any advice?? I can run as many test you need...but I really need to get it to work cause I'm often in a situation where the battery is dying and I need to charge it but I don't have any plug around me!!
i use something similar - new trent and it works fine.
Ok ...I searched over the net the product you suggested just to get some info and ran into these 2 usefull reviews which give some hints on the issue:
1-
"This product does not work out of the box with a Nokia N900 as, like many external battery packs, it does not conform to the USB dumb charger specification (the data pins of a USB dumb charger must be shorted before a compliant device will assume that it can draw current in excess of 500mA without causing damage).
Therefore, out of the box, this product does not work with the Nokia N900 or any device that complies with the USB dumb charger standards. This can be resolved by using a dedicated charge cable with the USB data pins shorted, such as the one available from Proporta, but it's a shame it didn't come with one, or with the pins properly shorted such that conventional USB data cables would also work.... [cut]"
2-
"The USB port is not wired correctly!
If you use a normal micro USB cable (rather than those horrible tip adaptors), your phone will only charge at 500mA - the rate of a 'data' USB port. My HTC Desire HD will show that it is connected to a 'USB Charger'.
The New Trent is wired incorrectly; To be a 'charge' port, pins 2 and 3 should be grounded. This tells the phone that it can pull 1000mA from the charger - the HTC Desire HD will say it is connected to an 'AC charger'. ie. it charges in half the time.
So check what cables you're using -- you might be taking twice as long to charge your phone than is neccessary!
2 ways around this - use the flimsy supplied cable and bulky tip adaptor, or use a cable that has itself been incorrectly wired like the one that comes with the genuine HTC car charger. (This cable has pins 2 and 3 grounded -- but remember that it should be the port that 'announces' whether it can deliver 500mA or 1000mA not the cable -- in theory if you used the HTC charger cable in a data USB port on your PC, you could blow the USB port because the phone will be 'told' it can pull 1000mA but the computer's USB port can only guarentee 500mA).....[cut]"
Ok..now would be really nice if anybody with some knowledge could tell us a work around when this situations come up: should I start researching a USB/MicroUSB cable JUST for charging purpose? I doubt I'll find anything similar on the net.... :-/ any other suggestion??
Nobody has any technical knowledge about this issue??
If you have a friend who might have electrical and elettronic knowledge could you please link him this thread??
Just get a cable and short d+ to d- inside the connector towards the phone, problem solved.

What he mean - if you look at a usb-connector, you could see 4 lines inside. The two outer ones, left and right, are used for 5v plus and minus, the two inner one's are data plus and minus!
To tell the phone that it can suck more than the usb-standard 500mv, the two data-lines have to be shortened! So the phone knows, that it isn't connected to a normal usb-port (pc, laptop or so) and it could get more than the normal 500mv from this port.
Sadly, this is a common problem with most after market power supplies and also with this external-battery-loaders like the mobile Gum - the data-lines are not shortened -> phone thinks, it's connected to a laptop or pc -> load'S with a max of 500mV!
If you're brave enough, you could try to manipulate the connector of the Mobile Gum Pro or a usb-cable to have the data-lines shortened out and your phone will load with the max. mv, whatever your phone accepts!
But if yoou manipulate the cable, be sure that you don't use it anymore for a normal usb-connection - doesn't know, if shortened data-lines will destroy anything, but surely it will not work anymore for transferring data!
i bought myself something like this too...V-Tank..have u tried unticking the usb debugging mode in settings>applications>Development?

Allright, I could give it a shot, what I can't get about all this it's that the same cable didn't work if connected to the Gum Pro but worked flawlessly if connected to the car charger (the one you plug into the "lighter" hole)..!!
I mean, surely from the car charger it would have carried much more than 500mV ...so why with the Gum Pro it didn't work out??

Yep, already checked and it's not ticked!
It is really quite simple, the car USB charger obviously internally shorts d+ to d-, so will work with an ordinary USB cable and the phone will indicate "charging (AC)" in settings, about, status. you can achieve the same thing by modding the cable instead of internally in the charger or micro USB connector (with a standard USB cable).
I don't know what this debug suggestion had to do with charging, it had nothing to do with it.

I apologize if this is a dumb question, but I'm not exactly an electrical engineer. I was looking at buying one of these for my room: http://www.thinkgeek.com/gadgets/travelpower/e81a/ and it says it outputs at 2 amps. i notice the stock Samsung charger is 1 amp. Will I be doing any harm to my phone by using the wall outlet vs. my stock charger? Or will it detect it as a USB charger, charging it at a slower rate?
Ya it'll be fine, it says UP TO 2.1amps.
Also it says it charges all mobile phones that accept USB power.
yes it will work. I have a few of these installed in my house. Your device will only pull the amount of amps that it needs. The voltage is what you have to look out for...
it will work, but it is not up to the 2011 nec code as it doesn't have tamper resistant shutters, I would recommend this instead.
http://www.amazon.com/Cooper-Wiring-Devices-TR7740W-K-Combination/dp/B007NC5GI4
It works the same, is up to the latest electrical code, is cheaper and will work with a standard wallplate.
Thanks for the input everyone, I think i'm gonna spring for one (may not be the Thinkgeek one though, as the one cade80 posted and a few other's I've found are cheaper) at some point, just to cut some clutter from my bedroom a bit.

Good eye on that, depending on your needs this may outweigh the being up to current electrical codes.
most third party charger will not charge you samsung smartphone at full power.
to charge at full power you must shortcut middle pins.
"will not charge" - not correct, your phone reduce it
So I went ahead and decided to not spring for the ThinkGeek Charger, and instead bought one of these: http://www.lowes.com/pd_369050-6337...&pl=1¤tURL=/pl__0__s?Ntt=usb&facetInfo= and just put it in a standard plug to test it to make sure it worked. Well I plugged it in and the first thing I noticed was the GNex was taking a while to recognize the plug. Finally it started Charging (USB Though) which was OK with me. Well last night I plugged it in via my Samsung Charger to a standard power strip because I hadn't gotten around to installing the RCA plate yet. Well I woke up this morning and it was on like 50% power and wasn't charging. So I was like WTF. So I brought it into work with me this morning, and now when I plug the stock Samsung charger with the stock samsung cable into the wall, no charge. I tried plugging it in to my computer, and it eventually makes connection with the computer (it's not instant like It used to be) and Android File Transfer starts, but says it can't connect to the phone. Then it charges for a few minutes, up about 1%, then stops charging. So my question is, when I plugged in my phone to the RCA charger last night, did it fry my phone? Or is my charge cable maybe bad now? I haven't tried another cable yet (everyone at work is an iPhone user and doesn't have a Micro-USB cable lying around) but I'm going to try that and hope it works. If it's not the cable, is it possible that the phone itself got damaged? If so, how could I go about removing root and wiping it to take it into the VZW store for replacement without USB to the computer?
Another new development. I plugged it into a Windows Box (I was using a Mac) and when I plug it in, it says "This Device can perform faster" and talks about plugging it into a USB 2.0 port. I'm using a 2009 Macbook Pro, it has USB 2.0. It won't mount the disk either. So i'm really beginning to wonder if the USB cable is fried.
Turns out it was a bad USB cable. Went to Best Buy and bought a generic cable and it now charges and hooks up to the computer just fine. My ADB doesn't seem to be working though for some reason, on Mac or PC...
Ok, everything is working now. ADB wasn't working because of a conflict with EasyTether on my Mac. Thanks everyone for the suggestions but I've decided to just stick with what I have now (power strip) and not deal with it.

May I recommend you return the Best Buy cable and go to monoprice.com?
I bought five cables from them that are 6 foot long. They work terrific and are higher quality looking than what you get from Best Buy.
Hello xda members, i have been experiencing a problem on my tablet Samsung Galaxy Note 10.1 (2014 Edition) Android version 4.3 since the past month. It does not charge as usual and a red cross pops up on my battery icon indicating slow charge. I don't know if it's the adapter or usb cable which is causing this, but I tried a set of new charger and cable ( Sony brand ) and still I get the red cross.
What do you advise me to do?
Do i install an app from the store to check if my battery is causing this or do I need to try charging it with a new original adapter and usb cable?
Thank you and awaiting your reply.
The red cross only indicates that the tab is not recieving enough power and even if energy is coming in, it is not enough to charge while using. Understanding this, anything can be cause for the current not being enough:
The adapter could be damaged.
The adapter you are using is not the samsung one and thus is giving less Amperes(Out tab needs 2A and most adapters give 850A-1A).
The cable is damaged.
The cable you are using is not prepared to transport 2A.(This happens to me with the chromecast ones)
The microUSB port on the tablet is damaged. An indicator may be the tablet overheating like crazy when charging but this is not probably because when this happens the device, in most cases, takes energy or not.
I personally find that the cable, if you are using samsung's adapter, is most commonly the problem. Using a cheap cable or a damage cable causes this for most of the tabs I have known.
Hope this helps.

Thanks for replying mate, actually I'm using both original samsung adapter and cable which came in the box.. I will be heading to some shops looking for a Samsung cable and see whether it resolves the problem or not.. What is weird is that sometimes it has the red cross and sometimes it doesn't. Yesterday evening it was slow charging and this evening it was normal charging.

It happened to my brother, he changed cables and changed from light socket and he said he had no more problems; he also may have cleaned the usb that goes into the adapter; ol' "blowing nes carthige" style. I would recommend getting a Q-Tip with alcohol and cleaning every metal part you see in your cables, speacially the 4 metal bands inside the male and female usb port from the adapter and the cable(remember to let it dry before pluggin it again).
BTW, it must be a good cable but it is not necessary for it to be a samsung one. If you have a good phone around and can use that cable, it should be fine(I use a motorola defy one which had a 850mA adapter and it works marvelously; "meh" cellphone but the accesories are darn good), just dont use other adapters because of the Amperage difference.
Also, if you are using any kind of extensions, specially usb port extensions, don't. They are a sure culprit of the problem you are experiencing. I dont know why but these cheap electronics really affect the energy passing through; maybe its the cheap copper or bad solder.

I've had my G4 since almost launch day and within weeks the supplied USB cable stopped charging the phone. I thought it was a cable problem, but it worked fine with other devices.
I tried other cables with the G4 and these still charged it so I thought nothing more of it until charging degraded with every USB cable I own to where the phone would only charge 20-30% during an overnight charge and the phone would frequently not recognise it was plugged in at all. I contacted LG who did a repair under warranty and all was fine.
I've now had the repaired phone back for about 3 weeks and the same problems are starting up again and it's only a matter of time until I am forced to return again for a repair.
Is anyone else having similar problems? I thought I may have just had an unlucky manufacturing problem, and the LG reps confirmed that to repair my phone they basically replace all the internal circuit boards and components rather than just replacing the individual component that is faulty (in this case the USB/charging port)
Basic debugging includes asking stupid questions, so please forgive but still answer any of those
Are you using a different charger? If so, check if that one is within specifications and if you do send in for repair again, use a different charger.
Are you propping up the device at an odd/weird angle or in a dock of some sort with the cable attached?
(As they replaced the entire print, it's probably not this, just the USB-micro port bent or broken.)
You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

You could double check the wall outlets being used, there might be some kind of electrical problem there.
Either using all kinds of fancy electical testing gadgets, or stick a USB light into the hub or charger, does it flicker?
When sending it back for repairs, did they check the stock charger as well?
Hopefully these questions help you find any logical or plausible cause.

Hi FreezyExp,
1. I am using the standard charger that came with the phone, but this has not been repaired/replaced. I have tried other chargers too, but all the same issue.
2. No weird propping up or anything like that. If I hold my phone while it is plugged in it is constantly vibrating as the charger connects and disconnects, and if I place it on the desk to charge I have to ensure that I have at least 3-4" of cabe "on the desk" to give it enough support to make the connection.
3. Wall connection is fine and I have tried it with a range of outlets around the home, both with extension sockets used and plugged directly into the wall and there is no different. No flickering light when using a USB light either.
4. When I sent it back all they asked me to return was the main section of the handset - so no battery or rear cover, no cables or chargers etc
It does seem to be the same issue as last time, a USB connection becoming loose from the main motherboard, but it seems weird that I have had the same issue twice in the space of 4-5 months.
I've been having some sort of problem with my G4 usb port. If I plug it in to a computer, it will lose connection and get a connection again if I barely touch the end of the cord at the phone end. I've tried many different cords and different usb ports on my computer, but it still has problems.
I can't fast charge, either. When I plug it in to fast charge, it actually starts discharging even faster. I've had some extreme battery life problems, too. It drained from 100-36 the other night with everything disabled, and it's been doing that kind of thing a lot lately. I'm guessing that the charging port is what's messing up my battery life because it won't charge correctly.
Never dropped it or anything.
I got my G4 on January 24 and my USB port has also failed. I am getting a replacement from Verizon, but am concerned that a six month old phone has this issue.
I also own a G4 H815. A while ago the phone started not receiving any charge from the cable and I would have to prop it up from right under the cable's micro usb end. Thought it was because it was bent inside the port and not making connection with the cable so I had the port replaced. Now I'm experiencing the same problem and I think it might be the cable that's already gone kaput and is effing up the port itself. I took the phone to the same place to get the port replaced again and bought new cables (I lost both the original adapter and the cable, which were charging slow anyway. Now using a 2A Asus adapter which works great) and when I asked the guy at the repair shop, he says it's a chronic issue with G4 devices. I don't really understand how it would happen twice in just a few months even with a new charger port. What should I make of this? Did they replace my port with an already faulty one, cahrged me full price and now trying to sell this bogus or am I really doomed with this phone?
