Problem with charging cable

Hi all, anyone else having problems with their charging cable? Basically mine no longer goes into my desire! I've compared my cable to my partners and it looks like the 2 locking pins on mine are stuck in the lock position, like the cable is plugged into the phone. I just can't seem to get them to release! I can't push the cable into the phone as these little pins must click into little grooves or something that possible shuts a latch that holds the cable in place. My girlfriends cable goes in fine though, so at least I can still charge it. Has anyone got an idea on how to sort my cable?

the htc charging cable is sh*t quality imo, My phone fell off my desk while it was charging and it stopped working aftestill r that. Thankfully, nokia uses the same usb cable when I was using the e71. Their's is much more sturdier. My desire has fallen from my desk a few times now and it's still good to go. I'd try and get a nokia usb cable if you're looking for a new one. Just my 2 cents. =)

Are you saying that HTC cable is bad if u drop your phone to floor a lot?
Is this USB cable only thing that keeps your phone on your desk?

MicroUSB cables are cheap to come by So a replacement isn't exactly going to cost a bomb.

Just Mobile Gum Pro - charge failed - HELP needed

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.

Why do only official HTC USB cables give full power charging?

I've read that some 3rd party cables/chargers only appear as DC due to not having shorted data wires but that doesn't explain what I'm experiencing.
I have an official HTC mains plug and car socket plug and when I use the included USB cable I get full power charging of upto about 800ma with phone on. However, with both, if I use 3rd party cables it still shows as AC but I barely get 3rd of that, say up to about 300 max.
What would be causing this and any tips on a reliable source of official cables in the UK so I can be sure of getting full power when using other chargers etc?

Are you sure the cables are shorted?

No. But the HTC ones can't be either as they are also data cables yet they still give full power unlike the 3rd party cables, - even though they are plugged into the same plug. It doesn't make any logical sense.

The official charger unit from HTC have an Hardware different. To charge with full power you need an original one!
There are a few other Provider they do the same. For example Samsung:
mobi-test.de/allgemein/aus-samsungs-trickkiste-nur-original-ladegerate-liefern-volle-leistung/

This is an easy answer. They want you to buy their cable. It's the exact same reason that laptop companies might design a proprietary shaped plug. If it breaks, they want you to buy from them to increase their profit margin.
****ty, but a fact of life.

1) there is NO difference in cabling. You can use any cable with MicroUSB, it makes no difference.
2) the official charger has the data pins shorted, but so do other chargers - for example my Nokia charger (rated up to 5V/1200mA) charges the phone exactly the same as the HTC one. I prefer the nokia charger because it has much thinner cable and doesn't heat up nearly as much as the original charger.
It is possible there are chargers with pins shorted but rated for <1A, they will either withstand it, blow some magic smoke or stop working after a while.

are there any cheap charging cables out there? in white would be perfect!

HTC modify the Cable to charge with only 500mA, if there is no original One. It doesent matter how much Power the Charger will have. With unofficial Cable it will only use 500mA.
Maybe this effect will only happen on original Kernel.

Cable

I'd like to buy a new and extra cable (not the charger) to connect my device to my computer and charge it then as well.
Apparently this kind of cable, micro data usb, seems to be universal. Is it really so as I don't want to damage it if I buy a generic cable.
Any help me would be great

I was also wondering this because I would like to buy a much longer cable since my power outlet is far from my bedside table.

The cables are universal, so any length would work for charging (data transfer not guaranteed).

Actually they are not that universal. While I dont have any technical specs there are quite large differences.
eg a PC USB slot will only deliver 500 mA UNLESS certain pins are connected that allows the connected device to tell the PC that it can take more than 500 mA. They will look the same but 1 cable will only deliver 500 mA & a different cable could deliver 1000 mA.
Another cable might be wired up for delivering power only from a USB slot or from the wall adapter, but at the same time not be able to do any data transfer.

To be sure I bought an Htc official cable.

You could always just buy a usb extender. That way you can use it for multiple things.

USB cables
Sorry to revive a dead thread, but there is some unclear info in here that I thought I could clear up:
Micro-USB cables are universal in the sense that they will all fit and to one degree or another charge your phone. The combination of the charger and the cable, however can yield wildly different charge rates. If you want fast charging:
1. Look at the small print on your wall charger and see what current level it will output. You're looking for something 1 amp or higher. Some chargers will say something like 500ma, which is 500 milliamps or half an amp, and that's slower.
2. Consider buying a special "charging" cable. These cables use the USB power that would normally be used for data to charge the battery faster, and thus they won't work as data cables when plugged into your computer. Here's an example of a charging cable from Amazon:
http://www.amazon.com/Mediabridge-U...1367955673&sr=8-2&keywords=usb+charging+cable
Basically what you want to look for on your One V is in the power settings for the phone it should say "Charging (AC)" when you plug it in and *not* "Charging (USB)". With the AC setting you know you're getting as much charging power as you can get.

I use my old Blackberry charge/USB cable with my One V without issue.

Yeah, I don't even use my HTC cable anymore. I originally stopped using it because I dropped my phone while it was plugged into it and it bent the connector. However, I HATED how short it was!! Then, I noticed that my Blackberry cable had the same end on it, and I've been using that for USB tethering, and I use my Samsung bluetooth earpiece charger to just charge my One V. lol
Oh, and I use the HTC USB to wall socket adapter to plug in my ecig. XD

ah nicee!

I unintentionally bought some blackberry ones to have in my car, at my PC, at work, etc and they work great for me. I am just really careful about the wall adapter output because using my dad's tablet charger with micro usb killed my wife's optimus t.

USB wires, right and wrong ones?

I have a 2meter USB to MicroUSB cable(EBAY) plugged into mains which does Not charge the phone when screen is on. In fact it Loses charge when watching films .
But when l plug in the one that came with the phone (1 meter) it charges the phone no problem, regardless of what you are doing.
Anybody have any ideas for why this is happening?
Length of wire? or just bad quality of wire? But l have tried a few different 2m ones. Same drain.
(Also same results with different roms)
Cheers me dears
(Was getting no traction in accessories)

You might have noticed that smaller the phone, the larger the charging cable comes with it.
and the larger phone, and tablets have decreasing charger cable lengths. Also, the charging cable become thicker as the device becomes more power hungry.
This all comes down to a simple explaination that longer and thinner cables have more impedance, and thicker and shorted cables have less resistance...
This is to cover up for the amount of power the device will consume in order to get charged, and hence, result in a different "quality" of charge.
Also, some cable, like that of Nokia, do not run on touchscreen samsung phones. This may also be because of the difference in power output, as they may not fulfill the requirements which the latter needs.

Ok, so how about getting a beefier longer wire? I've seen a brand one for 10 £ claiming to be grippier blah blah. Obviously no claim for what it's able to charge and how fast.
Will this change anything?
I'm guessing im doomed to be always leaning in to the wall if wanting to use the phone and getting it charged.
And thanks for explaining things, sadly that is what I feared.

It is not definitely that beefier and shorter wires will charge quickly/better. They need to have correct power ratings and other j7mbo mumbo, which is most definitely best in the stock charger you get

Just buy a usb extension cable with plug and socket on each end. You have to use the Samsung charger AND the Samsung USB> MiroUSB cable. Beetween you place the extension cable.
The reason is, in the Micro-USB-Plug of the Samsung-Cable, i think there is a Resistor between pin 4 and 5 that makes the Phone change into high-charging Mode (AC-charging).
Otherwise on USB-Charging you have only 500 mA. That is not enough for the Note 2, if the Screen is on. The Phone will not charge.

Thanks. .. should of tried that. Forgot I've loads of them.

Same here, with random internet cables it just doesn't charge fast, but yes with the original.
I was looking for some good cables to use it but I didn't see any info to know what are the faster ones for charging.

Right, some bad news regarding USB extenders, I used a 2 meter extender with the white stock Samsung cable.. screen on, torrent app downloading, did NOT charge at all. But did not lose anything either.
I then found a 0.3 meter USB extender with stock Samsung. And it is charging, but I would say it isn't as fast(very close to normal), but the main thing it is slowly charging. Make what you will of this.
My USB extenders are from ebay crap

I have a s2 original charger
Output 0.79 takes 7 hrs to charge note2
Original note 2 charger is fast charger
Output 2.00 tkes 4 hrs to charge the phone
So it depends upon the uotput of the charger as i use the s2 usb to charge wt note 2 charger and again used the note 2 usb to charge 5he phonr at both time the chargin time was same
So i think the length or thilness of the cable dosent matter only thing matters is the charger output
Secondly if u use nonoem cables or chargers the usb port may give off or ur phone freezes while chargin so pls avoid nonoem cables
U can use oem cables of sony , htc, blackberry, even micromax and spice in india which r runnin androud but dont use first copy of chargers ir cables as they would harm ur phone
