i just bought a retractable sync and charge cable and i was dissapointed to find out that even though i get the charging staus and light when i connect it to my pc the battery doesnt charge it actually gets drained. im using logout wm5.
what do you think is the problem is there others who share my dilema?
have you tried another computer? it can be affected by the PCs USB power ability
Look if you have a red (+) shortcut at last (22) pin in connector at your cable. If so, cut it.

Hello,
I have looked at all my mini USB cables and they are all 5 pin, but only a couple charge the phone when its connected via ActiveSync usb cable, the other ones never really charge this power hungry athena..
How can I tell which cable is which other then seeing if it charges?
Also which cable is better for flashing?
Hi,
I've used a USB charger on all my phones for a few years now. Just plug phone in on my desk and no worries. However my new Defy doesn't seem to take a charge from the USB on my network device (it's not a full PC). However my HTC HD2 could get a charge from it so:
1. Is the Defy more power hungry that it won't charge from an ND (I assume NDs put out less power over USB than a PC)
2. Does it just not show on the battery on the Defy that it's charging?
3. Have I missed something simple? I've gone into USB connection and selected charge only. I can't install drivers on the ND though, could that be it? The ND hasn't said it's found new hardware either though.
Thanks in advance for advice
motorola has a notorious reputation on this, they require a usb driver to be installed for charging some of their phones...
i think there's some strange combinations at work about this but, just use a standalone charger and it should solve the problem.
Thanks. I thought it would be that.
Bit short of plug sockets at work but I'll figure something out
Another point to note is that the Defy is very fussy regarding USB cables. A lot of cheap ones will pass data but no charge.

Would you consider hacking a usb cable to make a charging lead? A standard usb lead plugged into a PC will try to enumerate with the PC before it starts to draw power from the PC. However if you hacked a usb cable and shorted the DM and DP lines on the phone side, the phone 'should' detect the cable as a mains charger rather than a PC, thus enabling charge without any drivers on the PC. It would be something like the attachment...
Thanks for all the replies. Although my USB cable wasn't cheap and was capable of charging an HD2 which must be more power hungry than a Defy, it turns out the Defy is really fussy. It's charging fine through the Motorola USB lead on my network device.
My USB loading experience
Hi,
just to share my exp:
- loading with most USB loaders: fine
- My Car loaders and my multi power adaptor with usb can load everything but the defy
- on Computer no problem (some say you will have better battery performance when loading on non Computer: I can´t see a difference)
- cable doesn´t change anything

I've bought a couple of USB cables from ebay. My Defy seems to connect and disconnect when using them, like it has a loose connection. If I use the Motorola one, of course it's fine!
I had recently purchased the C6502. At work I do not have AC power outlet to charge the phone. So I generally used to charge my old smartphone (LG Optimus 4X HD) with a blackberry USB cable. I used to charge my old phone by connecting to the monitor's USB port using the blackberry cable. Though the phone showed as "Slow charging", it served the purpose.
But now using the same Blackberry USB cable and the same USB port, if i try to charge the C6502, it just lights up the screen and does not show any charging indication or the notification LED light.
Am I missing something here or the phone charges only with the original Sony provided USB cable?
Note: The same USB cable and the USB port work perfectly fine for other smart phones my colleagues are having like Galaxy grand, Lumia 610, HTC Desire SV etc. Of course when connected to the usb port all these phones are showing as slow charging, but they do charge slowly. But my XZL does not even charge. So I am definitely sure the cable and the port are perfectly fine.
Is there a way I can charge my XZL with the USB cable using the USB port?

Let me explain it more clearly.
At my work the USB ports on the CPU are disabled. But the monitors are having USB ports which can be connected to the CPU through another cable, so that USB devices can be connected to the monitor's USB ports insteading of leaning till the CPU under the desk. But those ports are not connected to the CPU so the ports on the monitor just act as a power source but not as data source. So we use the monitor's usb ports for charging our devices like phones, ipods etc.
As i had already told that my XZL screen lights up when connected to the port using the blackberry cable, but no indication of charging as well as no LED light. Same case with another colleague's Xperia SP.

as simple as your device does not detect any pc therefore it doesnt accept charging depends from phone to phone

So sony does not support "chaging only" mode using USB cable. How pathetic !!!. Supposed to be a "Smart phone" but really do not understand why cut down basic features.
Can anybody confirm if this cut down of a basic feature is a standard for Sony phones?
No buddy usb charging works when pc is on!i checked it doesnt charge when main supply is on bt cpu is off but it charges when cpu is on

USB charging
I have observed two things -
1) Yes, it does not charge in some cases. I have a power bank cable, with this cable it charges for some time but then it just stops charging without any reason. If you reinsert the plug, it starts charging again.
Other times, it does not charge with USB ports, for example my car music player's USB port. But what I have noticed is, if USB connectivity mode is changed from MTP to MSC or vice-versa it works.
Also some cables do not have two spring notches, and fit quite loose. In such cases pushing cable vertically up or down gets it charging again. But this is very very rare case.
2) I was not able to charge it from front USB port of my PC, but when connected to back USB port, it was charging fine.
My conclusion is, it does not charge if charging rate is too low or mode is incorrect.
I would suggest, try with original Sony USB cable in your office and check if it works. If still it does not, change connectivity mode. Else its a cable issue(not exactly, but phone and cable have some mismatch).
PS - I had similar problem with my chinese tablet. Out of more than 5 cables, It charges with only one cable from Nokia(it does not even charge with original tab USB cable ). I think there are separate data pins and power pins. But data pins can double as power pins. I think there was some damage to the tab USB pins, because of which data pin no more works as power pin and hence it does not charge and requires cable having power pins. Can somebody throw more light on this?
Relax its just u need a pc on to charge it it happens in my case too n my phone works fy9 with any cable

This is really strange. I can't connect my new Tab S 10.5 to my imac with the usb cable. I've replaced the cable and power brick but to no avail. When I connect the device to the power, there's a small red "x" on the battery icon and no charge is going on. But when I use the same cable and charger on my S5 it works, charges and connects to my imac. What am I doing wrong with the tab s?
Expecting its charging needs to match your phone...
I believe that the red x on the battery indicator shows that the USB source does not meet the power requirements to charge the device (can't deliver enough current).
I get this when I plug my Tab S 8.4 into my monitor USB port (PC not Mac), but it doesn't stop my Tab S from connecting via USB. So while I have the red x I can still transfer files to and from the device and it doesn't seem to loose any charge, it won't recharge. I hope that makes sense!
I think that the connection problem that you are seeing and the red x are unrelated.
so i have two usb cables and original. 2.0 amp samsung wall charger, the samsung cable i use for wall charger at home so when i setup my s3 as a AP i need constant 2.0 amp from charger keep up with the demand and charge the battery at same time but now i cant do that i have turn off hotpot and leave the phone alone so i can charge. i brought in my car usb cable, and now i can hotpot and charge at the same time no problem, so what is the problem with other cable? i mean cable still works and i still can use it for data transfer etc...
just cant use as heavy demand cable.
I have some cables from the "box o' cables" we seem to collect that have the same issue. Some of them won't keep up with the s3 others won't keep up with my n7. I notice it more with older cables so it seems to me that its the cable breaking down or wear on the contacts inside the connector itself.
