Is there a fix for the USB (no)charge bug??
Are you using an xda1 usb cable?
I'm using the BoxWave miniSync, it says "xda" on it, but BoxWave who sold it to me as an adaptor for the XDA II say it's the same, they also sent me the following email today:
"We are aware of the issue, and it is not a problem with the miniSync as you
may suspect. The O2/XDA II has a software bug the prevents charging from
low current sources, such as USB. If you have a unit that has the
attribute, you should contact HTC or the brand which your XDA II is made by
and request the bug fix.
The problem does not exist in every XDA II, which is why HTC did not make a
public announcement regarding the bug. We have done in-house testing to
confirm this, as our wiring structure is identical to the stock connection,
with the only difference being the incoming power current levels."
I've got one's, wried as :
+5v -> pin22
UDC+ -> pin 14
UDC- -> pin 15
GND -> pin 18
it can sync on XDA II, but can't charge when battery less than ~60% from USB port (more battery is ok).
Do I have to change GND to another pin to force my XDA II charge?

I have tried the usb charging on 2 pc's. On the first one it started charging very slowly then basically stopped charging as I used the device.
On the second machine it charged very well regardless of whether i was using it or not. I was also activesyncing on the second machine.
I bought the Pocket PC Tech's Lil Syn, which is very similar to the BoxWave product, and the USB sync/charger drained my battery.
I read BowWaves response that only some MDA2 or XDA II have a problem with this, but what I find interesting is that I can charge via USB on the cradle regardless of how low my battery is, but I seem to have issue with the Lil Sync product.
Why would this be? Is the cradle more powerful than the PPC Tech or Boxwave products? That does not seem likely.
It seems if the cradle does charge, but these other products do not, then the problem would not lie with the PPC Phone-2003.
USB Sync & Charge cable.
Okay.. I was a little Pissed when my cable wasn't working, so I started looking into the differences and found that ground was going to Pin2 on my sync and charge cable, where my stand alone charger didn't have that. So I snipped the wire that went to pin 2 and walla, it charges now.
I still am having problems getting my battery pack to work. It's a pack that takes 4 AA's and is supposed to charge it too. It supplies more Volts than the USB, but it won't start the charging process. I'm going to try and wire it more simpler to my USB Sync/Charge cable and see what happens.
Let me know if this helps,

as ive replied saying on other posts......
XDA 2 charger kicks out 2Amp max XDA only does 1amp max
most charging assesories are XDA 1 compatible only yet people say they work on the xda 2 means they have found out they plug in simple but they dont kick out more then 1amp as usb ports can only handle 1amp max.
thats why it doesnt charge it might charge if you turn your device off and disbale activesync from waking the device up but it will take twice aslong to fuilly charge maybee longer but if the device is awake youll find that the device is using up more power then the usb charger can give out so in otherwords your device will die instead of charging itself up.
gaz
I have a standard xda1 sync/charge cable and it charges my xda2 regardless of the amount of charge left in the battery, and it does it very quickly too, I think it is a bug in some of the xda2 machines.

Hi: can you provide your pin configuration for continuous charging while idle or being used.
I have this adapter that came with my xda2, is the wiring correct for use in a car adapter charging? Thanks.

do you have a pin config for your second m/c. Thanks.
Further to my earlier post, my xda2 now no longer charges from the usb sync/charge when the xda2 is low on battery, this only happened since I got my first "low battery" warning, I put it on charge, looked a few minutes later and it had gone from 10% to 7% battery power.
Hi all, pls look at this post... the non-charge issue can be addressed... http://forum.xda-developers.com/viewtopic.php?t=5438
Best regards,
Very strange problem , can not charge my Atom with the AC charger, the stupid charger charges my Imate JAMin, and JAMin charger wont charge my Atom,
The funny thing is it charges fine through pc usb :shock:
any ideas.
i have exactly the same problem, did u end up figuring it out?? its driving me nuts
I had this issue also, this time with a ghetto charger (that comes with a port for plugging in your USB cables). The ghetto charger works on my Mini, but the Atom stops after 5 seconds. Only the charger that came with the Atom works on it.
Unfortunately, there's no solution for this. Quanta apparently had this safety-locked just like Motorola did their RAZR series.
found out that motorola v3 razor charger could actually charge your atom, thx for your help
LOL... I KNEW IT, I KNEW IT. THE EXACT SAME CHARGER LOCK MECHANISM. >_>
Really? Does it charge as fast as the original charger? Can the original charger be used on a MotoRAZR? This is a very nice hack, tho not quite as useful as some might hope. <_<
im not sure if it would work the other way around, i cant see why not.
charging speed is about the same, but don't quote me on that one
cheers
to cause a short circuit on the plug pins,haha,it will be ok
hi all,
i am encountering another problem... opposite from wats happening to u all. my usb is not charging my atom exec when the battery is 35% or lower...
does anyone encounter the same problem?
I have a tytn and had the same problem, can charge and sync thru usb but no luck with the ac-charger. Thou yesterday i noticed if i leave it on in the ac-charger long enough it actually starts charging. Weird but i've tried and it really worked the cpl of times i tried. It takes about a minute or two before the led turn orange.
Same problem here. It charges on USB but not on my original AC charger. Has anyone already found the reason for this?
We have generic and "öther brand" branded chargers here in the Philippines. I've experienced the same problems both with the AC and Car Chargers here until I used a voltage regulator for the AC charger and a motorola car charger. Those that worked with my xda2 doesn't work with my atom. My advise to those with the same problem is to either buy a motorola AC or Car Charger whichever you need or use a voltage regulator in tandem with your original AC charger. If your PC USB doesn't charge while syncing with your PC, format your PC. Chances are, it's too cluttered already.
Hope this helps
how come it says in the manual that while charging the atom, it will display an amber/orange light?mine is displaying a red light?and i am encountering the same problem when charging. it charges for 5seconds and it will stop. the battery indicator displays a full bar.but it is not actually charged.can someone post the specification of the original charger that came with the package?i just bought a new charger here in singapore since i left my charger in the philippines.and the original charger that i got is for atom stealth. will it be okay?
My battery discharged while I was travelling - it went to <10% and shut off by itself. I left the original HTC microusb over seas and so I used my old Motorola microusb to try to charge the phone. After leaving it overnight a number of times I thought the battery was dead. I ordered a new battery (from Mugen) and tried to charge that.
All I get is a flashing orange/red light. The phone does not turn on.
I have tried charging on both the AC charger and via PC usb port.
Are all MicroUSB cables universal? I can't get a straight answer about this from HTC's customer support. Every time I call someone gives me a different answer which leads me to believe that they have no clue what they are talking about.
Is there anything I can do to remedy this?
The HTC AC charger is rated at 5V 1A, while my old Moto charger is rated at 5.1V 850mA. Could I get a charge by using slightly higher voltage with lower amperes?
I really would like to avoid sending it back to manufacturer warranty so if there is any other alternate route I can take please let me know.
I have some cheap MicroUSB cables and they seem to charge very slowly compared to the HTC one. There may be a difference, but I suspect the cheap cables are just plain cheap.
No the Motorola charger wont have done it any harm, 0.1volt wont make a difference, and charging at a lower current is less likely to cause damage.
Could I have damaged the phone by using a different companies' cable?
Is there a chance that the phone is FUBAR? Should I be able to turn it on if its plugged into a power source even if the battery is dead?
please excuse the bump
need to know
*bump*
I've actually tried all the different combinations of charging and they all seem to work fine
I've tried a cheap microUSB cable with the official charger, official microUSB cable with iPhone charger, cheap microUSB cable with PC, another cheap microUSB cable in my friend's car, and even a Nokia microUSB cable in all the mentioned combinations
They all just gave different current readings (from CurrentWidget) but in the end they all worked well. I'm not sure if a Motorola microUSB would have modifications that cause incompatibilities though
I also tried different Micro-USB Cables and my DHD still works normally.
me too have the same problem. I got a total of 3 diff USB cable. One give me 330mA, one give me 120mA and one gave me only 50mA. i do not mind spending the money if i know how to choose a USB cable which can give me 330mA everytime i charge. Anyone knows how to spot the correct ones?

Any Blackberry USB cable should work..
used Motorola cable many times. No issues.
Might be a fluke that u busted ur phones charging system.
The USB cables are all the same and have no effect on charging current. The charging current is determined by how the two data lines within the cable are terminated in the charging device. If the data lines are left open ciruit, the phone interprets this as being a USB charger and will therefore only draw a maximum of 500mA to prevent damage to a PC's USB port. Chargers that are capable of delivering more current (such as a wall charger) connect the two data lines together. The phone then interprets this as being a charging device which is capable of delivering a higher current and will draw greater than 500mA. If you look at "Menu - Settings - About phone - Battery" it will state either "Charging (USB)" or "Charging (AC)" depending on what you are charging from.
Hi all, just came 3 days ago from an htc hd2, and so far I am more than happy with it.
I have only one complaint and maybe you guys will help me sharing your experience : I can't charge this phone in my car while using gps.
It seems that the power adapter is not powerful enough to charge the phone screen on.
The car charger has a 5v 1000ma output, more than the regular wall charger provided by Samsung and it was working well before with my HD2 so I have no clue about this problem.
Did you experience that issue too, else can you share what car charger do you use?
try to buy new standard car charger with micro plug.. 13 eur and you will be saved..

Charger doesn't matter unless the phone is dropping into USB charging mode - phone limits to around 600-650 mA by default.
Custom kernels can bump this limit up for I9100 users. I777 users are screwed - we've got a crippled charger chip.
I had the same problem, I used the samsung one, useless, so I used my iPad charger, which is 2A, and charges the iPad quick, still useless. We drove from Bathurst NSW, down to Melbourne, about 10 hour drive, plugged in all the way using GPS, and about an hour from home, the connect to charger warning came on!! So once I stopped GPS, it started taking charge. Looks like when the phone is in use, it draws more then it takes charge, plus I read somewhere on here the phone is limited on the charge it takes, so using the 2A does nothing different then the stock 500mA charger.
I always had this problem with my Nexus One, although they are different phones, the problem is the same, uses more power then it can recharge in USB mode.
After trying 3 or 4 different charges I remember that I found one ultra-cheap 'made in taiwan' from a street seller that worked very well.... so it's kind of a lucky shot!
good luck!
Im using a genuine Samsung SGS2 charger and I can charge and run Sygic just fine. I started my journey with 80% and 40mins later I was up to 91% when I stopped and got out. (not in aeroplane mode..)
Very interesting feedbacks... So that confirm that is clearly not a matter of output amperage power.
It is now the same problem on the galaxy tab 10.1, for quickly charge this tab you need the Samsung compatible usb adapter.
It can be likely with a tab bringing a proprietary plug, but I didn't thought it will be the same with a Samsung phone bringing a regular micro usb plug. Quite frustrating and disappointing!
I will search around a micro plug car charger as suggested by redzion, but actually I don't clearly see the difference with my usb charger + a micro usb cable.
Double post, sorry.
If I use the usb cable from my cd player I have the same problem but if I use the official Samsung car charger Ithe only problem I have is the phone getting stupid hot

Oh Samsung, when you will understand?!
Samsung DOES follow the USB charging standard - it goes to its highest current setting when a charger that follows the standard is connected.
Note that iPad/iPhone chargers do NOT follow the standard - Samsungs will treat these as USB hosts and limit to 450 mA instead of 600-650.
Modified kernels can increase both of these values on I9100s.
The only thing Samsung really did **** up is counting screen/CPU current usage against the charge current limits - that's just stupid.
So the charger has smarts. On the i9000 factory chargers, the data pins were bridged. Bridging these pins manually on a USB cable when connecting to a USB source (such as a PC) enabled full current charging. You can see this in Settings -> About; it will say either USB or AC charging.
Do you think this is the case with the i9100?
I don't condone testing this theory on your i9100. Increasing the max current via custom ROM may be a safer solution.
I had the same problem. Two things fixed it for me:
1) I bought this charger: Sony Ericsson AN300 Micro USB 10€
2) I am using a custom kernel now
Any charger that is rated at 1000mA or more (per port) will do just fine. The problem is the cable - you need a quality microUSB cable, or it won't provide all the juice you need. I had the same issue, and I swapped three chargers until I found the real culprit.
Try with the charger you have now and the mUSB cable that was in the phone box - it should work well with that one.
I just press the power button to turn the screen off. when i need the sat nav i press the power and it still tracks you so there is no delay. With the screen off it does charge.
same problem

You are right, but even if it is better than nothing the charging time is still a big problem.
Yesterday I drove for at least 40mn phone off. Arrived to destination, I turn the device on: it charged only from 0 to 5%
I would like to test the mariusi theory concerning the Samsung micro usb cable, unfortunately on my SgsII box I just have a wall charger, no a microusb-usb cable.

Is there a way to know before buying if the charger respect this charging standard?
I have some cheap usb chargers here and no one is a fast as the one provided by Samsung.

Maybe for safety purpose? Gps phones can become very hot behind the car glass.
Samsung are trying to "encourage" you to buy only their official accessories. To do this they've wired something differently in their chargers and cables. This "problem" exists on the Galaxy Tab too and can be solved with this adapter...

It's cheap and turns a trickle charge into a full charge. I don't know the specifics of what they've done, but their USB charging just isn't the same as most others manufacturers.

Great find.
Pretty sure it just bridges the data pins.
Hey guys
First, I hope I'm asking at the right forum. I searched at xda and it seems to be closest that fits. If there is a need to transfer it to different forum please do or let me know there to.
Than, I have a big problem and I do hope you can help me with- my Cube-i7-Book don't charge not by the Wall charger nor by the Usb-c charger.
I read a lot about the coube-I7-book and just before they started talking about the new one I bought it (+original keyboard). It arrived and I start using it about 3 moons ago.
1. Last moons I bought a Aukey fast USB desk charger (charge other devises ) and try to charge my cube-I7-book with the USB-c cable I got with my LG smartphone. It looks like the charger is connected but it doesn't charge (I try again and again).
2. Last night my cube-I7-book buttery was very low. I connected it to the wall charger as I always do and went to sleep. In the morning I took a look at the cubeI7-book. I was surprise to see it was still charging. I let it to continue charging. At the evening I checked again. It got 61% and stop charging. I re connect it to the charger and to a different wall socket - there was no reaction. I restart the cubeI7 book -nothing.
3. Could the problem is in the wall charger? If so what different charger l have to look for in order to check?
4. If it's not the charger, what can it be and what can I do to make it work? It is a new device and I really want it to work.
5. What about the USB-c charging? Why isn't it working? Can I do something about it?
Thank you for your help,
Did you manage to fix your problem. I have the same issue. Did you try to use a macbook usb-c charger, instead of a phone usb-c charger?
Only just seeing this, sounds odd. USB charging works well for me (although sometimes I need to unplug and replug the cable if charging doesn't start right away). You need to make sure that your USB c charger provides "power delivery " and in particular, I think, 12v charging, maybe 9v is also OK, but the standard 5v that some USB chargers provide is definitely not enough.
You may have a look at the forum on techtablets.com, there's a subforum for the i7 book with wire a few people active.
