Hi,
i needed another microusb cable, so i bought ca-101(nokia cable).
And data transfer works fine, but charging doesn't work.
What is funny, phone indicates charging ,but in fact it doesn't charge...
So, i compared two cables and it seems that, they are almost identical.
The only difference is that from one end of cable to another is 7ohms (this cable charging properly) and on cable that isn't charging, there is 26ohms.
So, conclusion is, that poor quality cable have too high resistance and this cause problem with charging.
has anyone experienced similar problem ? Anyone uses ca-101 cable ?
Regards
i've got the ca-101 and it charges without problems.
thanks for info, it means that i bought crapy cable...

Hi,
I'm getting some problems charging my Hero. As of last night, it's stopped taking any charge when connected to the mains (with the supplied USB cable and 3pin plug usb adaptors).... although when I connect it to my laptop, it seems to charge?!
It worked with both without issue until last night... although I do typically charge it at work via usb (except weekend, hence why I only noticed it last night).
Has anyone experienced a similar issue and know of any way to fix this?
Thanks,
Brian.
I've also tried both charging methods while the fone is switched off.... and it behaves the same way.
:-(
have you tried another charger? maybe an older style HTC MiniUSB charger (if you have one), cos it sounds like your charger's died.
Did you use the same cable for both methods (the supplied one with mains adaptor) if you did and it worked via pc/laptop then you would guess the mains adaptor has died.
I would say that your charger is dead. Power supplies on them blow sometimes, maybe from power surges, maybe they're just made poorly.
Try another charger.
Try unclipping and reclipping the pin plate. The interchangeable pins sometimes come loose.
Hi everyone, hope someone can advise.
I have a UK TG01 and it works ok but overnight it wont charge from the mains charger but it charges via usb.
I have tried different chargers and an old HTC mini usb charger with a mini to micro adapter fitted but its still the same.
I have the Mugen 1300Mha battery but its the same with the standard battery on all chargers.
I have cleaned out both the charger plug and the socket on my TG01 just in case of dust but no good it only charges via usb.
I have hard reset and flashed the standard UK Orange rom but this makes no difference.
Does anyone know whats going on? it was fine, no changes or software loaded and one day its fine and the next day it wont charge??
Any advice would be gratefully received, thanks for reading.
Faulty USB sockets i think try send it back to Toshiba for warranty repair.
Not sure about that as my TG01 does charge if I plug it into my laptop, this would suggest the socket is ok?
I believe that the charger is faulty, try a new micro usb charger, or try another socket

Agreed. As the TG01 is charging via USB, then there is most unlikely to be an issue with the uUSB socket on the phone.
To tell the TG01 to go into charging mode, the uUSB connector on the charger must have the two data pins shorted out. This is the equivalent effect to connecting to a host laptop or PC when connected via a USB sync and charge cable.
If you have a non-standard charger or are using an adapter from eg. mini-USB to uUSB it is very likely that this will not be implemented.
A few questions...
- Are you trying with the supplied Toshiba charger ?
- If so did it work OK with this before but not now ? [likely duff charger]
- If a 3rd part charger, again has it ever worked ? [if not then probably missing the required pin config]
Hope that is of some help.
Hi Kevin, its a genuine Toshiba charger and I have been using it since day one.
I took my charger into work today and tried a friends Nokia micro usb charger and that worked first time so duff charger.
No, I asked him to try my Toshiba charger and that also worked
So I assume my original charger possibly may not be 'shorting' correctly or presenting exactly the right resistance to the TG01 or possibly my TG01 is getting a little fussy about how it charges.
Anyway I have ordered a genuine Nokia charger from ebay and fingers crossed all should be well and thanks for all the advice everyone.
I have a Samsung SGS2. This charges fine off the original charger (650mA) , a new trent usb power pack (450mA), computer USB port (450mA) etc using a variety of cables.
I purchased a USB charger from a major retailer (B&Q) and found that when charging the phone a) had a totally unresponsive/dodgy touchscreen b) actually barely charged. Swapping the usb cable I was using for some cables seemed to fix the problem, but most didn't work.
However using the "failing" cable in a amazon kindle usb charger, and again the phone charged fine.
My conclusion is that the replacement usb chargers are faulty in some way - or at least not compatible with the SGS2. Possibly down to perhaps data pins not being shorted or similar.
Interestingly the exact same issue is observed on an HTC Sensation further suggesting it's the charger to blame (we have 2 of them - behave the same)
Can anyone explain/elaborate?

The unresponsive touchscreen you experience when using the charger is the result of the charger creating too much noise (ripple) which disturbs the electric field of the capacitive touch screen. Hence the digitizer is not able to work reliable anymore.

Shorting the data pins will allow the phone to identify the charger as such, compared to a standard USB port. The phone will then draw more current then it does if it detects a 'regular' USB data port. From that point of view shorting the data pins should not have any influence. However if more current is drawn from the charger the ripple will increase and therefore the disturbance of the touch screen could aggravate.
In the end the problems you are experiencing are due to a charger of poor quality.
None of my micro USB cables will charge my E970 without a "slow charging" notification except for the cable that came with the phone. Even the venerable 6' monoprice cable isn't up to the task. HTC cords aren't cutting it, either. Does anybody have any 6'+ (ideally a 10') micro B cables that will charge the phone without slow charging? My monoprice 6' cables (i have a bunch) barely keep the phone from losing charge when serving up LTE hotspot, where as the LG cable charges it whilst doing whatever I can to suck down as much current as possible.
Also, I really don't want to short data cables. Somehow the stock LG cable does full current while maintaining data capability, and that's what I'm looking for.

OEM LG cables can be found almost anywhere used so that shouldn't be a problem. Otherwise, you may be looking at the wrong end of the cable. I have a spare tablet plug charger that puts out up to 2 amps and that seems to be what works best for me no matter what the cable. You might want to look for one of those instead of just buying more cables.
FWIW....I had the opposite result. The cable and adapter which has been near my bedside for the last year (for my HTC EVO 4G) kept giving me the slow charging notification on my me LGOG. If I used the LG adapter and cable all was well, but it was shorter than I wanted. I changed out the adapter and kept the older long cable and still got the slow charging notification. It seems most of my existing cables have this issue...even when using the new LG adapter.
I have not looked into power capacities on the usb cables since I charge each night and don't need to recharge during the day. Didn't expect there to be a throughput difference, but the new LG cable does seem to be different.

What is the part number for the oem charger and USB cable?
I use a Samsung charging cable with my LG plug and it charges regularly. I love the Samsung cable because the mirco-usb plug is asymmetric so I always plug it in correctly the first time, every time. Even in the dark. The cable is pretty long too. I don't use the Samsung plug because it only outputs 0.7A though.

I also use a cheapo USB male to female extender that I got off eBay at my gf's place and it charges just fine too.
I'm having the opposite problem, I have had my phone for a month, out of no where the original charger is throwing up slow charging icon. Wierd

Same problem here, just started about a week ago. It doesn't matter what cable I use it keeps switching between slow charge and regular charge.It charges without problems when the phone is off though. Also when I plug my phone into my pc it keeps disconnecting every few minutes. I'm starting to think its a problem with the phone itself and not the charger or cord as they work fine with all my other devices just not the Optimus G

I use all sorts of cables and so far the only time I see "Slow charging" is when it's plugged into my laptop or one of my USB hub. Those are the only times I could narrow mine down to.
In the car I use cheapo monoprice cable and charger, in the bedroom it's using the charger and cable from my HTC inspire. By my PC I have a Belkin 6 plug 2 usb wall charger installed with the stock cable, and at the office an iPhone 1G wall plug. I don't think I have even plugged in the oem charger that came with it.
Hello everyone,
I was wondering if there is a way to increase the charge rate while connected to an MHL adapter.
I have a 2014 Civic Si that literally has an HDMI input for the head unit.
I bought an MHL adapter and it works very well other than a safety limitation that stops screen mirroring while driving, and the fact that even if I am just using it to get the best quality audio into my head unit with the screen turned off, the MHL adapter uses more current than it returns to the phone, resulting in battery loss.
I have the usb power connected to a 2 amp 12v charger that works fantastic when it is just connected with a regular micro usb cable so I know its not the charger.
I have found some evidence that there is a mod that can basically tell the phone that it is connected via AC to take more current.
Would be awesome if someone could provide this, or another solution to this problem. I imagine there are a lot of people like me out there who like to use MHL adapters but don't want their battery to die.
Thanks
Check the quality of the cord. If it's some cheapo one from like eBay or something that may be the problem.
I've found that some of my older degraded cords won't charge the phone while I'm using it.
Also if you roll/folded the cord up sometimes it can pinch it just right to not supply the right charging power.

To be clear it does show that it is charging (via USB) but its using more current than its getting thus end result is the drain.
It could very well be the cable - hence why I am asking if anyone can recommend a tried and tested solution of MHL + charge that actually charges it quickly.
Thanks,
