usb cable defy+ different than normale ones

My defy+ cable has on the mirco side two metal pins on each side. Normale cables got only two metal pins on the wider side of the mirco side.

Sorry, I don't understand you, but you can use standard microusb wires for data and charge with your Defy+ (I usually use a Samsung usb wire)

The cables i used on my htc Desire wont charge or are only use full for date transfer. When i trie to charge true my charger or car charger. It start charging and within a second i got a message that it is unconnectend and then connected again. And it loops.

Those aren't "pins" in the sense of providing data signals or charging current. They are more like small springs designed to improve the mechanical retention of the micro USB plug in the socket. They don't make any difference to the electrical or electronic function of the USB cable, beyond reducing the risk of a poor physical connection, or a loss of physical connection if the handset is moved which charging/transferring data.
My Blackberry charger's micro USB plug doesn't have them , but the short USB to micro USB cable which came with my noise-cancelling headphones does - and the only function of that cable is to charge the battery in the headphones. I think you will find that there are a number of subtle mechanical variations of this kind between micro USB plugs from different manufacturers.

I used with my Defy+ usb chargers and usb cables from Samsung Wave and Blackberry 8990 and all of these works property for charging and for data transfers.

Other possibilities are that the charger is faulty or providing a charge current which is slightly outside spec, or that there is a problem with the battery. I have seen problems caused by both of these kinds of fault (with third-party chargers and batteries) when using my Motorola USB cable.

Make non-motorola charger work?

So this is my first motorola and I had heard of the issues they have with non motorola chargers. Now I am experiencing it first hand. With the same ac charger I have charged many phones with and is capable of 1 amp output (D4 charger is only rated at 850 mA) my D4 struggles. With the device off it charged painfully slowly. While on it cannot even charge. It discharges while plugged in despite the charging indicator and reporting "charging (AC)" in status.
How does it know it is not a moto charger? Is it just about the resistance between the data pins? For most other phones shorting the data pins on the charger indicates to the phone that it is a high current charger and not a computer USB port. Is there a similar trick for motorola phones? I would rather not have to purchase an overpriced moto oem car charger. I have a perfectly fine 1.2 amp car charger soldered directly into my car's 12v system behind the dash. Can I make it work?
Thanks!

On a regular basis I successfully charge my D4 using both a charger from a Samsung Reality feature phone and from a B&N Nook Simple Touch, in addition to the one that came with it. I've also used a variety of car chargers.

Actually, so far I have only one charger that had any trouble charging the phone (it was a $3 charger with 2 USB ports), but the $3 charger with ONE USB port works fine, as does the Nook Color charger, Blackberry charger, and Samsung charger I have tried it with, as well as both my old car charger and Lenovo's always-on charging port on their laptops.

Not sure how it knows one way or the other. I've successfully used a few LG chargers to charge my D4. The only really hickup I've ran into is the usb cables from those lg chargers won't sync data to the phones when plugged into a computer, they'll still charge off the usb port but won't read as a usb connection to the computer.

Heh, captcha is trynply.
Every charger I've used, including an old charger for an EN-V, kindle, supplied, and various other phone chargers works just fine with this phone. Probably have a bad charger, guy.

Thanks for the replies. I guess I was wrong. My modded car charger works just fine. I guess its just time to retire the old charger that I have been using. I think it might be my old nexus one charger.

A more important question would be does the thing charge over computer-bound USB ports?
When you're without a charger, but there's a USB cable that fits your phone, sometimes a regular USB data port is the only that is around... even though it might take a really long time.
Try a computer bound USB port, then try your actual charger, again. Or do the hard reset (vol down plus power, hold until it actually does it), which is just like pulling the battery.
See how that goes.

It does in fact charge via USB port. In fact, it has a 'charge only' mode. Depending on how much juice your port puts out, and what you are doing with the phone, it will charge slowly/not at all, though.

from my experiences, the droid 4 will not accept lg microusb cables, the charging bricks work tho. i use a blackberry microusb on mine along with a Logitech and the stock moto ones. 1.2 amps is a bit high but not crazy sounding. personally, I charge at 1 amp.

[Q] Need a better charger cable when plugged into my work computer

So to my understanding the 2a that is supplied to our phones when plugged into the wall is due to the wall part and not the cable. Is there any difference in the cables that could provide me a better charge? I leave my phone plugged into my work computer most of the day and it doesnt seem to give it much of a charge. Is this something wrong with the USB port itself (can you systematically change the output provided on your computer? I wonder if t would make a difference in the front vs back usb ports.
Also I am not against getting a nice dock for it while its here at work but I like to keep it in landscape mode. If anyone knows of one available to keep it on with a clock or something and still eb able to charge it I would be appreciative.
Thanks in advance.

The computer usb ports are normally limited to 500mA. The oem wall charger is 2000mA. So you get 4x the current when plugged into the wall. On top of that some chargers have basic circuits in them that the phone recognizes so it knows to pull more current. If you want a fast charge use the supplied wall charger.

i do wonder about this too, as my iphone will charge (sufficiently) thru pc, but the note 2 takes forever

Do they sell or could you make a cable that has two usb plugs on the end, one that will plug into the computer for syncing and one that could plug into the oem wall charger for fast charging.
I would think you could use the two data wires in the usb to connect to the computer and the two power wires to go to the wall charger. Would be really easy to do and only require an old usb cable for the second male USB A end.
Does anybody have any experience with this or know if its possible. The dock seems to have this ability but I would prefer not to purchase an expensive dock.

Some of the more advanced PC motherboards out there have one or two high-current USB ports that can be set for dedicated smartphone/tablet charging. Most of these are Intel Sandy boards as far as I know.
FWIW the Perseus kernel charges far faster IME than the stock kernel.

The iPhone charges "more" than the Note 2 because the iPhone's battery has a smaller capacity. (1440 mAh vs 3100 mAh) so basically every 1% of battery on the Note 2 is over 2% on the iPhone.

Before I bought the note, I had a sgs with cm10 and a kernel that supports fast charge. It neglects the pins used for data signal on the usb and makes it a power source only, and I'm pretty sure I got around 1mah with this method though I didn't measure it.
Should be no reason for it not to work on our phones if a kernel supports the method.

Ok so this is my understanding. If it's a laptop they usually only have one usb port inside. its then run to a hub and from there split to all the other laptop usb ports that you see on the outside. so the power is usually lower than the 500ma. I thought the cable from cableforge.com was bad but it was just the low power from the laptop port.
This said USB 3.0 runs on its own line so it usually works better. now this is where i may be wrong isnt the usb 3.0 more than 500ma?

The iphone and most other phones charge "more" because they pulls the entire 500mA that the usb spec allows. For some reason, Samsung phones only pull 96mA over usb. A new cable won't make a difference.

[Q] Droid 4 charging standards

I'm trying to make a fast charging cable for use in the car. The current charger I use seems to work fine, but the coiled cable annoys me. When I use a standard USB cable the charging reverts to slow mode which means the GPS and screen drain the battery faster than the cable can charge it.
The charging cable that works has a resistor between ground and the unused pin 4, but what I want to know, is this the only USB charging standard that the Droid4 supports, for example does it support the one where you put a resistor between the two data pins, or the one where you just join the data pins together?
If it supports either of those, then this project just got a lot easier as I can just chop the Type A connector off my USB cable and do all the work without having to solder a Micro USB connector.

Could you de-solder the coiled cord and solder in a micro USB cord or even a female USB cord for removal of OEM usb... or is that what you mean in the last paragraph... If you want I could give it a try as I have three rapid car chargers and several USB cables...

I'm not sure if this has anything to do with your question but try an ipad or tablet charger (2.1 Amp) which i use on my droid 4 and charges it fast.
Regular chargers use 0.7 to 1.0 Amp. I know tablet chargers are bulky but they tend to charge your device faster.
Also maybe this thread will work for you: http://forum.xda-developers.com/showthread.php?t=1984838

I'm using a 2amp car charger with a USB socket at the moment and I assure you it isn't charging at that speed. The other charger with the coiled cord does charge at the higher speed, but it also has the odd wiring.
That thread is interesting, is exactly the kind of thing I was talking about, but I'm looking for confirmation that it will actually work with the Droid 4 before I start hacking up cables. The Droid 4 seems to be fussy about which chargers it will work with, my 2amp charger worked fine with the HTC Desire Z, for example.
Another part of my reason for doing this is I want to use the right-angled USB plug that is on my USB lead, but that Micro USB connector is sealed and unmodifiable.

I'm not sure but there is a radio called ihome ic50 (Google it) i own it and it has a special switch which the manual says if the device has a proprietary charging protocol flip the switch. I made a quick test and it charges in both ways. I'm pretty sure your idea will work as long you know what you are doing. BTW the ihome ic50 is pretty cool for any android device.

N6 won't charge via vehicle usb

It only shows up as a USB connection for media instead of charging. Is there anything I have to change on my N6 settings? My old iPhone charged fine.

Maybe it requires a higher ampere charger?

I have never had an Android phone that would charge from car's USB. Never knew whether it was the phone or the car. I can play music from USB thumb drives or some phones through the car's USB port. Always have to use the 12v charger. If your i Phone did, you might see if a "Charge Only " cable would work. That cable is a good thing to have, regardless.

Can you send a link ? I wouldn't mind buying one.

All android phones determine whether a charger is a wall charger or a computer by whether or not the two center USB pins are shorted. If they are, then it's a wall charger, and will show "Charging (AC)" in the battery screen. Wall chargers designed for iOS devices work differently, and as such most of them will only charge Android devices at 500mA, which is the the same as a computer's USB ports, regardless of the marked amperage. In other words, a 2A charger designed for iOS will still charge Android devices at 500mA.
"Charge Only" cables are also an issue. Many of them don't actually have center pins at all. Android considers this an "open." In a "short," the resistance is zero Ohms. In an "open," the resistance is infinity Ohms. (Infinity, being the exact opposite of zero.) So, a lot of charge only cables will cause your android device to charge at 500mA.
The solution is to ensure that your charger is designed for Android. Or, buy a charge only cable designed for android. Or, buy an adapter that turns any cable into a charge only cable designed for android.
Yes, I know that's all really confusing. Here's the real deal. Find a charger and cable that works for sure (oh, I don't know... like, the one that came with the device!). Plug it in, and go to the battery screen. Ensure it says "Charging (AC)". Once that's a given, replace the cable with any other cable that you want to use. If it still says "Charging (AC)," then it's a good charging cable. If it says "Charging (USB)," then it's not a good charging cable. If you ever plug a known good charging cable into a charger, and get the dreaded "Charging (USB)," then you know your charger isn't Android compatible, making it a bad charger.
So, the TL;DR of it all: Use the original charger to test cables. Use the cables that pass that test to test chargers. Other than that, it's a crapshoot.

Most "built in" car USB ports are 500mA, so will show as USB chargers (not AC chargers). Those that are higher (1A or 2A), tend to be designed for iOS devices (so will STILL show as USB chargers, unless you get a cable or adapter that has the two center pins shorted). I've yet to see a built-in car USB slot that will charge an Android device in AC mode.

That's a very hard question to answer. Chargers tend to advertise iOS compatibility, but do NOT tend to advertise Android compatibility. However, they often do advertise a specific android device. So, for example, you might find a car charger that advertises compatibility with the Samsung S5. As long as it's advertising compatibility with any Android device, it should work with YOUR Android device. Just be aware that most manufacturers don't understand the whole AC vs USB thing, so even if they advertise compatibility, it's not ensured. Just be sure to buy chargers where you can take them back for a refund if they end up not showing up as working in AC mode for your device.

Sounds like I need to search for chargers for my N6 to plug in my 12v.

Someone just posted this in another thread. It's a car charger that supposedly supports Qualcomm Quick Charge 2.0, so it'd be the equivalent of the Moto Turbo Charger for a car. http://www.amazon.com/dp/B00P9UILUM/ref=cm_sw_r_udp_awd_0fvAub0VPYE9B
Since that's an Android thing, it'd almost be certain to work for all Android devices.

Another hard question. There are two types of "charge only" cables. One that has the middle two (data) pins shorted together, and one where they're just missing (even though the pins themselves may be there... they're not connected). The former would work fine. The latter wouldn't (or more specifically, it would work, but only show up as "Charging (USB)" in the battery monitor).
Determining which is which before purchase is virtually impossible. The only way to really tell is to try it with a known good (1A or higher) charger.

Nope. They're designed to use that type of charger. Technically, rapid charging may decrease battery life, but you'll probably long since have moved on to a new phone by the time you'd have to worry about that. The only caveat is that you should NEVER start your car while the phone is plugged in (on ANY car charger). When you're starting your car, the 12V electrical system in your car can experience quite a large power surge, and that can transmit through the adapter and hurt your phone. The electrical system in your car is built to withstand that. Your phone isn't. Most (quality) car chargers will have a similar warning somewhere, since it's a pretty standard warning.

Personally would you go with the charger you listed above? Amazon also lists USB cables that my N6 came with which is model skn5004a. Should I stick with that type of USB cables for extra cables I carry while traveling, work and auto?
