HTC Fast charging ?

Hi,
I just stuck here, cause I found a thread about fast usb charging. But there is no answers or solutions.
I have many htc devices. It seems that some of them has a problem with 3rd party usb chargers.
My most used device is Universal. It suck a lot of power. THis one doesn't enable usb charging at all, until you put it in sleep mode before pluging the charger.
Anyway, the same issue for Kaiser too.
The problem is, that it doesn't matter how much current is the charger able to deliver. They just use some kind of recognition of original chargers.
What I already measured: Original charger and universal running => takes 1200mA. 3rd party charger or my 5A PSU => Universal/Kaiser sucks just 500mA.
This is fast/slow charge. I found here discussion about 4 and 5 pins shorted??
But WTF which 4 & 5 pin?
http://www.tracyandmatt.co.uk/blogs/index.php/2006/09/10/htc_hermes_usb_connector_pin_config
According to this pinout. It would be 2 GND of Audio side? I'm not sure that original charger use extUSB audio side to charge...? It also could be D & A pins, but I'm afraid to connect 5V to Data- pin.
Anyway, someone here have to know it.
If not, in a few days I'll try all possible combinations and post the results.
Thanks
Shef

I'd also be interested to know about this. When I charge my TYTN II via USB, it takes much longer to charge than if I charge it via the mains charger (I prefer USB since I travel a lot and it's one less charger I need to carry around).
Better still, is it possible to buy a USB cable that will charge at the same rate as the mains charger rather than messing with a USB cable with the associated risks?
Best,
Gary.

a usb port only supplies 500ma, while the wall charger does 1200ma as the OP has measured (although it says 1A at the back of the charger). changing a cable is not gonna superpower up your usb port.

unless maybe you get hold of a forked USB cable, like the one that Seagate Free Agent drives come supplied with... you know, 1 mini USB splitting halfway down to two normal USB plugs.
Worth experimenting with, do you think?

good call.......with a little googling i came up with this
http://www.universaluk.com/acatalog...2_x_Type_A_to_mini_B__USB_2_0__1m__Lindy.html
tried ebay, my brief search came up with lots of unrelated results, so i gave up

I got one of those leads, came with my portable 2.5" hard drive. Just tried the lead on my Tytn 2 and it does charge almost as fast as the mains plug

Success
Ok, so, I tried to experiment.
Here you go.
Usb simple cable 480ma charge.
The same result with Motorola charger.
Motorola charger pins A and B short circuit - 890mA.
That's much better, althrough I suppose it can suck more current then 890mA, but it's significantly better.
THere is also pins data+ and data- short circuited (I don't know if it has effect, but I can't disconnect it in this connector).
Apparently NC (not connected) pin on our pinout schematics definitely is connected.
With % of charged battery it suck less and less current....I suppose it's usual, this should be even driven by ROM.
So, update your cables
It works even with car charger, so no more charger problems...
Shef

Just to be clear - you took a Motorola USB cable and shorted pins A and B (which are which by the way?) and it provides a decent current....
How do you short the pins? I've looked in the end of cable and I can hardly see the pins, let alone short them! What's the trick here or have I missed something?
Thanks,
Gary.

Also interested in how to short the pins. I use Navizon, bluetooth HSDPA tethering, and iGuidance while on the ambulance and even my iGo 3A max rated charger can barely keep up because the tilt wont accept all of the available current.

So have anyone found a way to fast charge our ppc through usb??

Yes, that is correct. Short pins 4 & 5 (4 is normally NC) to enable fast-charging. If you do it correctly, the phone shouldn't pick up tethering, and therefore should not say "PC Connected" or the like..
The TracyAndMatt pinout is wrongly numbered. The pin assignments are correct, but the number/letter scheme they used is incorrect. True ExtUSB pinout translation to their pinout is as follows:
T & M Real ExtUSB
-------------------------------
Pins E D C B A = 1 2 3 4 5
Pins 1 2 3 4 5 6 = 6 7 8 9 10 11
The way I remember is that the corner opposite the angled one is where pin 1 starts (where E is on the T&M pinout) - and they go like most IEC-standard connectors, in a clock-like circular numbering scheme.
Here's a better pinout: http://pinouts.ru/PDA/htc_extUSB_pinout.shtml
Hope this helps!

its the milliamps that is the problem even doubling up with a y splitter does not do much Find a charger with the most milliamps for a faster charge 1.2 amps works best and as far as i know no usb port puts out that much even if they are wired in a series. Many try to sell lower amp chargers they dont even know about it at att. if the screen is off they will charge but not well these phones are energy hogs. I must have at least twenty chargers and messed around with them... the original or one of highest amperage works for me.

Check winhlp.com/node/855 for the answer.

Is it possible to get one of the 'fast charge' enabled USB cables on eBay or elsewhere? I am not keen on doing the mod described.
What is the maximum mAh recommended for HTC devices? Is it still 1.2 A or more?

Check http://winhlp.com/node/855#qaes for the only buyable solution I know, besides compatible chargers. Your best bet is probably the original HTC charger, available for roughly $10.

There can be no recommended maximum mAh. There can only be a required current, which differs from device to device. Check Ohm's Law. The device determines how much current it draws. If the charger cannot deliver that current, then the charging process can fail in various ways, all undesirable.

USB Cable type WILL affect charging speed

Hi all
Am a 4 day old owner of a rooted/bootloader-unlocked Nexus 4 with stock 4.2.1 and franco Kernel
On the first day it took me 6 hours to fully charge my phone (I put it down to me using the phone non stop whilst charging), subsequent charge attempts took on average 4-5hours which shocked me
Reading one of the threads here which recommended using this app called Current Widget (play.google.com/store/apps/details?id=com.manor.currentwidget&hl=en) to check if my phone is detecting charging from a wall wart properly.
I did this and realised:
- I charged fastest using the supplied USB Cable (Current widget reading was Averaging 700mA which when added to 450mA-my screen on power draw, gives 1150mA, close to the charger's 1200mA output)
- Tried 3 other cables and they did not charge as fast (got and average of 300mA to 500mA)
I looked close at the cables and beside length the only differences i found were the markings on the cables.
Namely:
Original Cable: Style 20851 80degrees 30v VW-1 28AWG/2C + 24AWG/2C
Others: Style 2725 AWM 30v VW-1 28AWG/IPC + 28AWG/2C or variations of this. (I tried 3 different cables)
To be sure i also tested this with other USB adaptors, I had an adaptor with 2.1mA output and saw the same results (Note: phone still drew only max 1200mA when the adaptor could supply more)
TL : DR
- The best USB cable to use is the ones that are rated "28AWG/2C + 24AWG/2C" with the marking on the wire itself.
- This is because the power is delivered over the thicker 24AWG rated wires.
- Purchased 3 more "28AWG/2C + 24AWG/2C" micro usb cables online to verify this, will update thread once tested.
Please test and share your findings here too!

Yep, less resistance from the thicker cable.

Comes as a shock to me as these cables I owned were used originally with my old blackberry (before my iphone days, this is my first android!) and they didnt make any difference to charge time, guess they were not drawing as much current and so was not affected by cheaper quality usb cables!

Agreed the one from my nexus 7 works wonders. Another thing is, believe it or not, plug the cable into the phone first than while connected plug it into the wall.

Is the cable that came with the phone USB 3.0? I remember reading on the nexus 7 forums that the factory cables are USB 3.0. It was the same thing with the nexus 7 it would charge quite a bit faster with the factory cable than any other microusb I had.

The second code after the + sign denotes the power rate. Anything lower than 28AWG, will charge faster. Which is why 24AWG is faster than 28AWG. The lower number, the better.

USB cable that can run at 1800mA

I've managed to find some chargers (both car and wall) that will charge with 1800mA (according to Galaxy Charging Lite app).
I have not managed to find an aftermarket cable that will charge at more than 1amp. Anyone know of an aftermarket cable that actually is capable of 1800mA? I've tried nGear and monoprice, and while they are very well constructed cables, they will only charge at 1amp or less with the n7100
Thanks for the help in advance, but please only respond to this if you've actually tested the cable with with the Galaxy Charging app or a current meter of some sort. I'm not interested in cables that only work anecdotally.

I'm breaking your rules (gasp) but as far as I'm aware, it's not the cable that manages the charge, it's the power adapter that feeds the usb, right? I've used all sorts of random cables on my travels for work, but always sticking to my 2+ amp output charger, and they've always worked.

Find a very short cable and you'll see rates up to 2100 ma (as measure by battery monitor widget). I use the short usb cable that came with my jambox combined with the the phones stock charger. The charger gets so hot due to the high current that I worry if it might burn out. The cable is very short, like 6 inches. I use this one when i need a quick bump before going out.
At this low of voltage plus high current, the shielding on most cables is not enough to protect against the voltage fluctuations caused by the high magnetic field. The longer the cable the more shielding is needed. Additionally, the cable shielding gets less effective as the cable gets older due to general wear. My original usb cable can only due around 740 - 1250ma, where it used to do 1800ma when new nearly 2 years ago.
If you could find a cable where there the positive and negative wires are separated in parallel strands like traditional AC power cords, it would also help. I have a cheap charger with built in cord like this and it charges consistently fast.

Most USB cables will work with the charger, but some cables (usually longer or smaller gauge wires) will restrict the charge to a lower amperage. I still haven't quite figured out how the phone knows what cable is being used, because, realistically, in a simple DC circuit, the consequence of using a cable that is too small is heating up or burning out. A cable that is too small alone will not prevent too much amperage from going through itself. This is why they invented fuses. Somehow the phone detects the gauge/length of cable being used and restricts the amperage being pulled from the charger by changing its own resistance on the circuit.

I suspect you're right. The impedance of a cable is the only thing that would change over a period of time that would result in a cable that could once pull 2A to start pulling less than that. Still, it would be nice to have a list of chargers/cables that consistently pull 2A before dropping $15-$30 on one of them. There exists such a list on this forum, but it is filled with comments like "It's good enough for me", without any real data as to what performance they are getting. Hence my rules above.

The charge rate depends on your kernal not the cable. I use Agni and get over 2 amp charges from a USB cable I paid 12 cents shipped for on eBay.

I purchased this cable about two weeks ago and it delivers!! I can charge my 9300mah Zero Lemon battery from 0-100 in just under 4 hours. Stock battery in about 1.5-2hrs. Of course I'm using a 2.1 amp charger, but NONE of my other cables come close. I'm averaging 1800-1900mah charge rate with it. Next highest rate cord only gets about 1200 max. I plan on ordering 2-3 more. $5 and change with PRIME.

Check this out. http://voyager8.blogspot.com/2013/04/how-to-choose-good-usb-data-and.htmlI found it while looking for the 6ft cable I used to use until it shorted from heavy use (bending a lot) and I got a pack of 10 short flat wire style 3ft cables. My 6ft one has a ferrite end and printed on it: 28agw/1p and 26awg/2c. It could handle 2A just fine, but this requires any wall outlet adapter that can output that amperage. The oem outlet adapter that comes with the phone says 2.0A output, but you can fine any 'reliable' one that has 2.0A output.

if the original cable is not 1800mA, there must be a reason

Got similar problems as the OP. I wanted to charge my phone in my car and using the phone as a navigation device without depleting the battery (which occured a few time).
Tried several usb cables, even did some mods like shorting the white and green data wire in the cabel at the phone side, but that all didn't help.
Then i came to Kopi who sells usb cables which can deliver a full current.

HTC Rapid Charger

Anyone bought it yet? Does it come with a special USB cable?
It is my understanding that usb 2.0 cables only provide a maximum current of 1.5 amp amp (charging only, no data transmission - see here http://en.m.wikipedia.org/wiki/USB ) , while the Quick-charge 2.0 tech pulls up to 3 amps so I don't understand how it's possible to provide such current.
Can someone please explain?
Cheers

It is the port that limits the current not the cable.

They also do. But not only.
Check here http://lifehacker.com/cables-can-significantly-impact-the-charging-speed-of-y-1532784722

I don't think you have anything to worry about as long as you're not using really long cables where you could see voltage and current drop over distance. Also only using original or at least avoiding the cheap eBay / Amazon ones.
Wire is wire at the end of the day, and for the low current we're talking about here it's not likely to burn up.

Just tried with the Incipio quick charge 2.0 car charger and the small micro usb cable for charging only that came with a anker Bluetooth speaker I bought a month ago and, while quicker than cheap car charger I had, the the amperage was a steady 1,3 amp, which dosent match with the "up to 3 amp" Qualcomm advertised

This could be a great reference tool to make sure you get a properly working, up to spec cable.
I got a value priced USB-C <-> USB A cable, but fortunately I'm just using it for quick data syncs to a laptop. I think I'll hold off on getting another one that I'd use with a charger until more of his reviews come out.

Good info in there, spotted this doing the rounds earlier.
Also worth noting that he is essentially saying that USB A to C cables should never charge at 3A, but only from 0.5A to 2.4A via "Default USB Power".
So, people looking for A->C cables specifically for 3A could be risking the health of their charger&/device.

Its not the device thats in any danger just to clear this up, its only the charger and a ton of other fail safes would have to fail as well. The likely hood of anything happening is practically nill! You can also pretty much thank OnePlus for this as all the cables that aren't in compliance basically copied the OnePlus 2's USB-C cable as it was the first one out and unfortunately the OP cable doesn't meet the standard lol I have been using the Orzly multipack with my OnePlus 2 for months and since last week on my Nexus 6P no issues. Personally i think its all been blown out of the water!

That was the biggest takeaway for me as well. I didn't know 3A wasn't possible with Type A to C. Good to know.

This one was given to me to test and review. It has a stated max of 2.1A which falls under the correct spec as described for type-C to type-A.
http://www.amazon.com/TechMatte%C2%AE-Charging-Google-OnePlus-Zenpad/dp/B01706YAXY/ref=cm_cr_pr_product_top?ie=UTF8
I was able to get it to report up to a max of 2.2A with a 2.4A charger in the Ampere app which goes over its rated max spec. Not sure if that is perfectly accurate though.

I have the one plus cable. Is my device at risk? I couldn't care less about the crappy old 1.5v Samsung wall adapter it is attached to.
Is the only thing at risk is my old, useless wall adapter? If that's the case I will probably keep using the one plus cable.

It sounds as if the charger, hub, USB ports, etc are what's at risk. Not the phone. Apparently the phone tries to pull 3 amps and if the device on the other end isn't rated to do so, then it can get damaged.

Hmm. I thought the usb type A connection couldn't do 3 amps. Even if the charger were rated for three amps, would the cable be able to transmit that much?
Also, can anyone else confirm if the phone is at risk, or just the cable and wall adapter/pc port?

From an electrical standpoint the phone is not at risk. Everything else in the chain is potentially at risk of failure or even fire.

This one was given to me to test and review. It has a stated max of 2.1A which falls under the correct spec as described for type-C to type-A.

I was able to get it to report up to a max of 2.2A with a 2.4A charger in the Ampere app which goes over its rated max spec. Not sure if that is perfectly accurate though.

Considering the techmatte usb converter failed the test, I'd expect the cables do as well.

IF you look at the specs, they state the cable max is 2.1A not 3A... so for whatever reason, my advanced smart charger had some sort of pullup and wasnt tricked with its connection into a 3A draw. Would be nice if it were tested though. From all my tests, I could never get it to go as high as 2.4A with a 2.4A chrager... Ampere only reported 2.2A which is within range of its stated max of 2.1a give or take for Ampere reporting error.
All that said, Benson stated that this is only likely an issue for anyone using these cables to charge from an older source, like a PC or old charger and that newer chargers all likely have brownout safety that simply shuts the charger down until it cools off, in which case you should see Ampere report the charger starting and stopping continually during the charge cycle.

Does this mean I should stop using my techmatte adapters?

Ugh, got the OnePlus cable and power adapter (wall charger). Any recommendations for a proper power adapter or would it not matter?

Its not the device thats in any danger just to clear this up, its only the charger and a ton of other fail safes would have to fail as well. The likely hood of anything happening is practically nill! You can also pretty much thank OnePlus for this as all the cables that aren't in compliance basically copied the OnePlus 2's USB-C cable as it was the first one out and unfortunately the OP cable doesn't meet the standard lol I have been using the Orzly multipack with my OnePlus 2 for months and since last week on my Nexus 6P no issues. Personally i think its all been blown out of the water!

There's nothing being blown out of the water here. Non SPEC cables should not be used in non quick charge USB hubs. And the likelihood of something happening is way above nil. There are already people reporting that their charging hubs are failing from using out of spec cables to charge their devices.
If you have an out of spec cable, its safe to use in a quick charge hub. It's not wise to use it in an old galaxy S3 charger..

Depends on the charger and what sort of performance you are experiencing, but for sure DO NOT use with a standard USB port on a PC or any older chargers.
IF I were you, I would get the Ampere app running and see if the charging cycle drops off and then restarts frequently and then also check to see how hot the charger is getting. IF you have a smart(er) charger, it will likely sense the amp overage and shut itself down until cooling off.

Your fine with that combo OnePlus designed them to go together!

I have the spigen C to A cables. They're hit or miss when plugged into my 2.1 A car charger, Sometimes it works sometimes nothing.

I would assume no matter what adapter you use and as long as you don't care charge time, as long as phone is showing "charging slowly", we should be safe from issues right?
Since the current would be so low and should stay within most chargers' range.
It's only when phone shows "charging rapidly", we should be concerned if phone is drawing more current than adapter was designed to do.

I can't confirm if the messaging reliably tells you what is happening with your charger. IF your charger is in process of melting and catching fire, I suppose it could report as "charging slowly" at the same time for a while. I guess it is also possible that messaging means it has negotiated a default basic low amp USB handshake. An app like Ampere might be abkle to show you if it is steady and low vs overheating and shutting down, cooling and then trying to start again.
