My HTC Diamond has developed an interesting problem
It will not charge from a mains supply but it DOES charge when connected to a USB port of a computer
Does the mains electricity pass through the same USB pins as the USB juice?
I am thinking a pin on the Mini USB socket on the Diamond might be broken?
Any other ideas? - is there anything software related that could be causing this?
I have stock ROM
Fanks
Bit of an (embarrassing) update
My mains powered docking station was not working (and still isn't)
To verify the problem I tried charging the device from the supplied mains charger in my kitchen - which also didn't work so I concluded the issue was with the HTC Diamond itself, especially as it charged from my laptop's USB port
HOWEVER - I just went to make a cup of tea and the kettle didn't work - the mains in the kitchen had tripped out - now reset the mains charger is working fine (PHEW!)
The issue is therefore my docking station and NOT the HTC Diamond
For info I did manage to find out the mains chargers DO use a different method to charge than USB connection
Mains is referred to as "Fast Charging" and shorts some pins to supply max power (and faster charging) of 1,000mA
USB power uses the standard 500mA from the USB supply so takes longer to charge and delivers it through the power pin on the USB pinout
Irrelevant now but it may help somebody else searching for a similar issue
I am now going to enjoy that cup of tea and hide my embarrassment!

I have a tilt that now will charge from the USB to computer connection, but does not charge when plugged into the wall with my wall charger (an after-market charger that worked fine until today). The phone says "charging" but actually loses battery power .. and after a while the orange charging light goes off.
Any thoughts -- sure is a drag to have to charge my phone through the laptop.
What after market wall charger do you have? Does it use the USB cord to charge? I'm assuming that you plug the USB cord into the wall charger and then into your phone. If so this will not work. The USB cable is only capable of trickle charging. If you are doing anything while it is charging over USB you will use power faster than the trickle charger can provide. You have to charge it with a wall charger that does NOT use the USB cable.
Yes I realize that the standard wall charger uses a mini-USB plug but the internals of the cable are not the same as a data USB cable. The difference in juice it can provide is like comparing a PVC pipe to straw.
I was just using a radio shack iGo charger with a usb tip ... it worked fine until my latest ROM upgrade.
Ahh I see. Yep the charger is most likely bad.
Before i got HTC Tytn2 i had qtek9000. I had also Brodit car holder and instalation in car with cool hidden cable for charging qtek. After i bought Kaiser i also bought Brodit holder for Kaiser. I thought that this miniUSB should charge battery but it is very strange. Kaiser shows "charging" but battery is not charging. On normal 220v original Kaiser charger it works like charm. Are pin combinationfor these two smartphones different?
As far as I know the pinouts are the same.
There is a blog here which describes the HTC ExtUSB socket and also mentions that there are 2 charging modes. The faster charging, higher curent, needs 2 pins to be jumpered. Without this fast charge the current is limited and may not be sufficient to actually charge the device if you are actively using it. eg. GPS, 3g, Music etc. Try using the charger with the Kaiser in GPRS only mode, or Radio off, and with no apps running, this will enable you to see if in fact it is charging but at the slower rate. The Kaiser may need more power than your Qtek needed.
do you maybe know which two pins?

Quoting from the blog...
As for the power pins question this is simple a case of juice.
If I plug the USB cable into a HTC device, then plug that usb cable into a usb port and just wire that up to a bench power supply... the device draws a few hundred milliamps. (As much as USB spec allows).
This device, much like other mobile devices I have used which USB charge, can barely draw enough power of the USB to run itself let alone charge the battery.
However, if you close the A/B pins you are telling the phone "This is not a USB port, its a 1A power brick" so the phone charges the battery at its maximum safe rate.
This behaviour is stop the phone frying your usb ports.

Hope this helps
I had problems with some cables and some car chargers. It turns out that when I use a cable for sync that is fully USB 2.0 compatible everything works. For charging in my car I bought a universal car 12v to USB converter. Then I am usinging the same USB 2.0 sync cable with it. It works.
When i first got my kaiser, i used the car-charger from my old MiO A701. For a period of 1,5 month, it worked just fine. After that, for some reason, kaiser shows that is charging but it really does not!
I thought it would be a charger malfunction, but after reading the posts above i have my doubts...
One of my Tilts suddenly won't charge on some chargers:
HTC AC charger - OK
USB to PC - charge and sync OK
HTC compatible car charger - no charge
Blackberry AC charger - no charge
My second Tilt is OK on all four chargers (as expected).
I am suspecting a problem with the usb connector but looking for a reason why some chargers work and others don't.
Any insights would be appreciated.
Thanks
I saw a few weeks back a thread on this very forum that examines this problem in detail -- keep searching
Problem Charging
I think I 've read everything relevant. I am looking for someone who has h/w insight into the Kaiser charging scenarios. I suspect mini-usb damage.
I am somewhat familiar with HTC's pin 4-5 implementation to detect a true charger as opposed to a usb connection that can also apply power.
I want to eliminate software possibilities.
How can a Kaiser charge from an HTC AC charger and also charge from a USB connection to a PC....but not recognize a car charger or a third party AC charger that does not implememt the pin 4-5 grounding technique to identify a charger (and not a generic USB connection).
That is where I am lost.
Looking for "inside-out" knowledge...not "outside-in", if you catch my drift.
charging problems
If the car charger worked before, you can do an easy test. Just put in the car charger and do a soft reset. If it starts charging than, its only a software issue. I did a modification on a charger myself. Because I have different chargers using a normal USB cable, my device didn't charge alway as well. I modified a standard miniUSB cable by connecting the 5th pin to ground. When I use this cable for charging I never have a problem anymore. Succes.

I had exactly the same problem after I tried to re-set my device by poking the stylus in the mini-usb port instead of the re-set hole (tryng to do three things at once!). The port was mangled, and once i'd pushed it all back it wouldn't take a charge from the genric car charger. I bought an HTC branded car charger and it charges as good as a wall adapter.
I imagine that your suspicion of USB port damage is correct.
Can i use a non sony cable for charging my X1 or USB transfer? It looks the same as a USB mini connector that i have but i'm not game to test it without your advice?
Yes you can. The only comment to make is the number of connectors in the cable. Almost all cables will charge & allow you to connect with your PC, a minority may just allow charging.
(I once bought one of those roll-up cables from Boxwave, where the cable is collected in a disc: it was sold as a charging cable, and yes, it only charged! In the same box there was a synch cable of the same design, and that both charged and sync'ed)
And re the charger, you can use any. Charging from the PC is slower, as will be some wall chargers with a low rating (amperage).
But you will not damage the phone, however much power (amps) the charger promises to provide: the phone will only draw the current it needs.
Thanks for the reply. I'll test my cable.
x1 is miniUSB a universal std like a normal AC connector
even other htc devices with extUSB rather then normal miniUSB is direct compatible with
all miniUSB cables for charging and syncing with computers
Hi, Ive been experiencing problems charging my X1. Its 18months old, it will charge from a usb port however will not charge from the original SE mains adapter (or any other Ive used). Any suggestions?
Wasn't it obvious? The main charger is broken?
But if you really want 2b sure. Maybe you can try this, (I tried this before on my ex-phone) Try to plug your USB Flash Disk to that charger. If you have USB flash disk with LED, you can see the blinking LED, vice versa.
Ive tried 3 different mains chargers! all with seperate cables, all which charge through the laptop.

3 mains chargers from sony ericcsson or appropriate charger for X1? I really have no idea.
It seems weird to me too. Technically it's nearly impossible that the charging process only works in connection with a laptop/ PC. I recommend trying a charger from whom you are sure it works (from a friend, from a store...). Maybe all of your chargers are defective (coincidences happen) or inappropriate (heed the output voltage and the maximum current provided by the charger).
X1 charges only from USB - broken phone hardware?
This thread is getting on a bit but just experienced same problem with my X1. WON'T charge from charger, WILL charge from computer USB or other USB. Bought new battery and new charger, tried various charger leads, no joy.
Finally tried making up USB charger lead from old bits connecting ONLY 0V and +5V lines, NOT data lines D+ and D-. Now WILL charge from both old and new chargers and better half's HTC desire charger, but presumably at USB modest charging rate rather than high speed mains charger rate.
I think it must be broken phone hardware which is happy with USB but when it detects a dedicated charger via the data line shorting in the charger now fails to switch over to high charging rate. Breaking the data lines tricks it.
Hope this helps. If anyone can point to a software fault rather than broken hardware feel free to make my day.
Cheers
This leads me to the question what roms you guys are using. Stock? Custom? 6.1? 6.5?
My ROM is stock R3AA010 1.05.931.10 dated 04/23/09. I flashed this over original Vodafone ROM in October 2009 and it has behaved itself when charging until now.
