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.

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.

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...
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!
My HD2 has just killed it's second car charger, grr! Has anyone else had this problem with generic micro USB chargers? Or genuine HTC ones?
The power light comes on in the charger but nothing happens on the phone. My car holder charger was in 2 sections, a mini USB cable to the cradle and then a converter to micro USB in the cradle. If you swap the mini USB cable the rest works, but with the broken cable, the cradle power indicator still lights up.
Thanks in advance if anyone's had the same problem or got some advice.

How hot is the phone?
If it is too hot (usually from a car charger in a hot environment), the Leo will not charge. The HD2 will blink green and orange.
Hello dizzi141,
Same problem here, already one car charger down. I have a red led burning on the car charger but nothing happens on the device ...
Grtz
My charger is working but charger is getting very hot and it charging the phone very slowly like 7-10 min one percent (%1) any way to fix this problem?
It's not a heat thing as far as I can tell, it works one minute and then next time it's dead. The phone doesn't recognise it's plugged into a charger even.
So the led is not blinking at all? (when plugged in to charger)
Shure that its your htc hd2 killing and not the car ? Cheapass chargers suks bigtime
Power consumption
Could it be that your generic charger is rated at 500mA and the HD2 can draw somewhere between 1500 and 2000mA ?
That might blow a fuse (or burn up the voltage regulator if unfused) in the "el-cheapo" car charger..
Personally, I'm using a 1000mA USB adapter from dealextreme.com
http://www.dealextreme.com/details.dx/sku.34040
and a standard USB cable.
Works perfectly for me.
(Sure, I might get the orange/green LED, but that's because of heat. I get that with original charger too, if it's too hot when I charge.)
Just my two cents...
I used to have a lower power generic car charger but it blew after a couple of months of occasional use.
For 'peace of mind' I brought the official HTC one as advised in the accessories section of their website, it's still working fine now after about 3 months of occasional use (just have to wiggle it around a bit to make a good connection in the socket sometimes).
I do have to align the screen mount to an aircon vent on the dash to keep it cool though, it overheats in no time - and that's just uk heat!
I haven't had any problems with heat or charging. I use this http://www.newegg.com/Product/Product.aspx?Item=N82E16882021129 , you can get them pretty cheap if you watch their email promos.
I'd agree with Bonzo.
I have tested few chargers (Samsung branded including ).
Everything what was not marked as 1A (1000mA) output was useless.
i use the origininale htc`s car chargers.
they work flawless.
CC-C200 for the hd2
i had a CC-C100 before.
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.
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.
Sent from my DROID4 using XDA
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.
