Hey Guys,
I have a query regarding charging my Hermes / 8525.
If I plug the phone into a wall unit, the orange charge light immediately comes on.
If I use the phone, or receive a call the phone continues to charge.
Once the phone has been used the phone/screen stays on.
When I plug the phone into my car adapter, the phone doesn't begin to charge until the phone goes into sleep mode. But then when I go to use the phone it stops charging. So if the battery is on it's last minutes, plugging the phone into my car adapter does NOT let me continue to use the phone. I have tried 3 different car chargers.
This week I bought an XTLINK Bluetooth Cell to Landline Converter. This is a great little box, and I love that once I walk into my house my cell phone rings through my phone system. Call Clarity is great.
But with the Bluetooth link active constantly the battery drains like crazy.
So I purchased a desktop charger unit. It arrived today. You can use it to charge the phone or with USB to synch the phone. So I plugged in the wall adapter to the cradle, and the phone only charges when not in use.
But when I hook up the cradle via mini-usb to my laptop the phone goes into constant charge mode - but it's doesn't stay on after being in use.
Can someone explain to me why the phone has these different charging modes ? Is there something I can do to change a setting to make the charging more consistent ?
Thank you,
Dave

no one else knows about this ?
I have the same problem with USB charging in the car when I was running vp3G's Rom. Now I switch to Crc's Rom and the problem is gone.
But my phone would stop charging if I use my GPS software thru bluetooth and bluetooth headset. In that case I just reset my phone and it would charge normal again.
I have seen this too. I don't know the exact details, but the phone checks the charging current when it is on, to see if it's within a certain value. If it's not, it stops the charging circuit to protect the battery. That's why it works when it is asleep. You'll need to buy a car charger specifically designed for the Hermes.
Yep, there is a long thread on car charging on the forum. Like the other uses says, either buy a HTC official charger or have a look at the other thread about soldering pins 4 & 5 together on the USB connector.
I have a generic car charger from a local electronics store that does not have a problem charging whilst talking over a bluetooth hands free and navigating using a
bluetooth gps receiver, however, I am using one of CRC's roms so that might be why.
The only thing I have found is that if I leave the charger plugged into the hermes when I start the car the hermes stops charging and will not charge again until I reboot it... disconnecting the plug before cranking the engine and then whacking it in straight after works around the problem though.
There is probably so much of a voltage drop when cranking the engine that the little DC-DC convertor can not keep the charge current up.

hi,
is there is difference between charging at charger or usb? charging speed, battery life?
whats your aprox. batt life for one charging?
What about car charger (there is lots of story that is no good for batt?) its a same jack for mda compact, jasjar and phone motorola v3! can use theese chargers safely!?
tnx!
I have a motorola BT headset with usb style plug so that users can charge headset and phone (ie V3) at the same time, I have tried it with my "spare" o2 xda exec and can confirm that it does not charge dispite the charger being the same voltage as the exec charger - I still cant see why it wouldnt work, unless its something to do with reversed polarity.
I've got a similar problem, I have a Leadtek GPS with a mini USB plug, the output is also 5v and 1amp as per the XDA's charger YET the XDA won't charge.
I presume the XDA charger is sending some kinda of data signal in addition to Voltage that tells the HTC unit to switch onto Charging mode?
I've disected a USB cable trying to get this to work, so has anyone got any ideas as to how to make a Y cable capable of charging the XDA?
I had the same issue with my old Motorola BT headset and the "two-pronged" charger. When I plugged in the car charger and connected the Exec....nothing. Until I turned OFF the phone and left the phone connected to the charger. Hey Presto! Charging light.
Now though the BT headset packed in and I've had to buy a G2 from Bluetrek.

Oh right! So you turned the Phone element off, or do you mean put the PDA on standby mode?
I'll play more with this later.
Pressed the power button.
Sorry, should have been more precise. With the phone connected, press the power button, wait a few seconds. You should see the green signal light flash a few times, then suddenly flash twice quite quickly. Finally, the charge light should appear.
Cheers
Ant
Dude, you're right!!!
I've just gone ahead, and made my Y cable by stripping two USB cables, joining, heat shrinking...
Plugged it in and IT WORKS!!
YIPPPEEE, that saved me a fortune!!
When I plug my MDA Pro into my PC it draws 460mA of current at 4.75V and the orange charging light always comes on.
I have bought a car charger - when the MDA Pro is plugged into that it also draws 460mA at 5.04V but the Pro doesn't always seem to realise it is being charged - the orange charging light doesn't come on and the backlight switches off so I cant see the SatNav! (when the light goes off the current goes down to 430mA)
The charger was bought of eBay from shop4hardware/PCglobe for £9.99 and it looks well made.
Any ideas what is going wrong? Has anyone got a 12V charger they are happy with - if so where did it come from and how much??
ceemjay the tight fisted
I bought a car charger off eBay, and while the orange light does come on and stay on, it doesn't seem to charge very effectively. If i'm using something like TomTom the charger manages to keep the battery charge level just about constant, rather than building up charge.
Is this a problem with the Universal? I had a Blue Angel before the Universal, and the car charger I had for that was very effective.

I had this problem too and solved it by purchasing an "orange" (UK mobile phone operator) branded charger for 10 quid from one of their shops. I have no issues now.
What i did notice when I had the problem was by ensuring the xda was off prior to plugging in the old charger, it would continue to stay orange when turned on. I think this problem is a common one with the usb cable & car charger adaptors combo.
i bought one from expansys, what i noticed:
1. It takes a lot of jiggling, pushing, pulling and twisting to get it recognised by the device (organge light on)
2. When it charges, it does so slowly, i think about 1% per 10 minutes or so, or about 10% per hour.
My two bobs worth anyway.
Many of the mini USB car chargers are simply not powerful enough to charge these devices. They all have the same voltage but the amps are different. I read somewhere that good M5000 car chargers should be rated at 1amp, I'm not sure about this but I've certainly had trouble with ones at around 600mah.
With the under powered chargers you often have to plug them in while the device is switched off. Even then it's not going to charge as well or as quickly. Getting them to start charging without turning you device off is just down to luck and patience.
My advice is to look for chargers that are specific for the M5000 etc. If it also mentions Motorola phones etc, then it's not going to have the required power output.
I hope this helps...
I bought an ORA one from a service station (phone bitz type shop), it was a bit expensive but I needed one in a hurry and you can test them in the store.
as per my earlier post - m5000 is orange branded htc universal, aka o2 xda exec. I believe mine stated it was for the spv500 and it still worked fine...
The universal wants a 2 amp charger really. the 0.5 amp from most chargers including USB ports just is not enough to do much more than stop your battery draining whilst your universal is in use !! other useful alternatives include the charger meant for the newish blackberry
Thanks for all the comments.
The charger that comes with the Pro is rated at 1A however I believe the USB spec only allows up to 500mA to be drawn (as I orginally posted it draws just below that) and I have never had a problem with charging via USB. Hence my confusion!
Is the charging software controlled and might there may be a bug which manifests itself under circumstances?

The Brodit active holder charges the universal first time everytime, and is a very good place to store the phone on the move. I've got a 3.5mm input on my car stereo and use my phone as my in car music source. If I could get a 3.5mm 4 pole to 3.5mm stereo plug and breakout mic it would be perfect since I could use it as decent handsfree solution, voice command can still use the built in mic when the stereo connection is inserted but the phone app doesn't.
The Brodit holders are nice. I prefer the unpowered version, so I use a separate charger cable. But I agree good holders.
My new M3100 is great, apart from one thing. I seem unable to charge it using any of the three in-car adapters I have that worked a treat with my Prophet.
Anyone know if this is an issue, or just specific to my M3100 (which appears to not be charging properly even when on USB or mains adapter)?
Cheers,
Sam
i have tried 2 different USB car chargers and neither have worked. Last one was 1A but still no joy.
Did you drain up the batt? I mean, was it full discharged when you attemped to recharge it? I have the same problem, no way to recharge it, at least the orange light doesn't show up.
If i try it at home, no prob. But what with a usb? no way
There are issues with some car charger USB connections.
I do not suffer this problem because I find it very useful to have an "inverter" permanently in the car. For those that have not seen these, it is a device that converts the battery voltage to mains supply voltage. This allows you to plug in as if you were at home. Handy for your hermes, laptop, phone etc etc without the hassle of special in car setups - just plug in with your normal mains plug. Most of these devices just plug into your cigarette lighter socket, although I have mine permanently wired in - so I also have the socket still available.
here is a UK example but I imagine they are available for all countries:

There is a known issue on car charging where the device will only charge when switched off. If this is your problem see the wiki here or my link below.

I've had that problem too. Strangely enough, restarting my 8525 gets the car charger to start working
try powering off your unit, it will get the orange light. Turn it back on after 5 mins and the charging will hold. not sure why.
I was having the same problem as mentioned above with a usb car charger that came with my GPS, however I just received my car charger from HTC FINALLY! With the HTC car charger and home charger, I have no issues charging the Hermes where I sometimes run into problems with say a generic motorola or igo power adapter - these sometimes require me to restart my device before charging begins.
By the way, I am going on a trip where I'll be away from power for 4 days ... can anyone recommed a portable cell phone charger that runs either off of AA batteries or solar power?
I think there is another thread about this somewhere, but I don't have time to look it up. I've had this same problem with several chargers that worked fine on my Cingular 8125 (HTC Wizard). History is that there is a firmware issue on the TyTN that checks for a data pin in the USB interface coming from the charger, and if it doesn't have the right voltage on it, the phone doesn't charge. When you totally power down the device (holding down power button for a while and then hitting yes to the power down question), then the charger works. It's when the device is in standby that it doesn't work right, because the firmware checks for the pin to be correct, doesn't find it, and disables the charging circuitry.
I was reading some posts a while ago about some car chargers not charging the Tilt. Back then I didn't pay much attention. But now I do have 3 car chargers and neither one is doing what is supposed to do.
I did some search but I can't find the threads. Can somebody help me trying to figure it why my Tilt won't charge? For the record, the battery icon recognizes the charger, I do see the yellow light at the top but after some time, I have less battery instead of more. This happens only to my car charger.
I have a brodit car holder (for the universal ...) and this charges the kaiser without any problem.
I also have a charger for a GPS, and if i connect this one it does not charge...!
sollution: in the energy-advanced settings you can specify if the charger should charge while syncing. If this option is turned of, it does not charge with the gps charger. and you guessed it, if turned of, it charges!!
ie: it says it is charging did not test if it actually does....
the box you mentioned is not checked. So I do allow my Kaiser to be charged while synking. I kind of remember has to do something with some roms updated but nothing else. By the way I am using Dutty's...
Q: Suddenly my car charger (cigarette lighter plugged) is not working anymore. After 5 mins. my device stops charging..... is there anybody having the same problem and knows how to solve it?
If it's after a period of time maybe a battery contact issue?

If you've already read the sticky posts relating to car chargers and your (mystery brand) charger isn't one of those, then maybe your phones battery terminals and connectors need careful cleaning with a cotton bud moistened with contact cleaner or IPA. I had a problem with my mains charger ceasing to charge my TyTN II after a minute or two a long time ago and after cleaning as described, the problem went away. Be sure not to spray the contact cleaner or IPA onto the phone or battery, only the cotton bud/Q-tip and then gently rub that on the spring contacts and battery terminals. How does charging via mains adapter or PC USB port go?

It still could be a battery contact issue as voltages may differ slightly when using the car charger compared to the other forms of charging. As an example if the Kaiser is set to stop charging when the supply voltage drops below a certain value and the car chargers voltage is lower to start with (and fluctuates with normal driving/electrical usage) then that may explain things. It's well worth doing this cleaning every so often anyway as a matter of course so give it a try and see what happens.
Additionally, could heat be a factor eg if it's sitting on a hot dash or near heater vents (the device is designed to not recharge above certain temperatures)?

Thanks for the advice, i will give it a try
if you have any adapters that allow for another usb input, nice a headphone adapter, or the HTC Multifunction Audio Cable YC A300, a ycable or anything with a USB in, try that first.
if that doesn't work, take the unit into your retailer and they will give you a new (or refurbed) unit, as your USB port may have a pin or two out of whack.
This may be weird, but my tilt used to charge just fine from most USB chargers(car, AC, usb cords). One fine day it quit charging off most chargers except the official AC charger from AT&T. I tried to fiddle with the USB pins inside as one looked like it might be a bit bent/damaged. No luck.
However, yesterday I noticed that My Settings->System->Power->Advanced settings page had following option checked:
'When device is turned on, do not charge the battery when connected to the PC'.
Once I unchecked it, it started charging of PC USB cables (obviously), but strangely enough also charging from my car charger(s). Hope this works out for you or someone else...

It is probably because your normal USB pin 4 and 5 in the cable of your other chargers are not shorted to signal that there is no data connection. So your phone thinks it is connected to a PC (or a device which might send it data), hence not charging the battery according to that setting
I have a similar infuriating problem, i have had a MDA VArio III for over a year now, had an issue with my last one and had a replacement issued in October. Now i have used the Brodit active holder (ciggy lighter version) since day one over a year ago and wit the new MDA as well. now all of a sudden phone will not charge in the holder, borrowed a friends active cradle still no charge, used a no brand usb ciggy ligther charger and charges fine!!!!
When phoe n is placed in the holder orange charging light comes on but phone does not charge and the light goes out 5 mins later!!!
any ideas anyone???
thanks
Matt

Problem solved - Pin 5 on my phone was ever so slightly out of alignment, bent back into place and all is now well! strange it only affected the brodit holders, nothing else!
Car charger failure explained
I also experienced this same problem and actually broke my phones mini usb plug in frustration at lack of charging. Got it fixed again though
The reason for this problem has become apparent since my phone was repaired. In your car, like my car when the heater is switched on it will gradually heat up the cigarette lighter socket. My charger cable like yours has a thermal safety circuit built into it. So when the ciggy socket heats up the heat is transferred to the charger plug and breaks the elec charging circuit. You might see me driving around London with my charger plug hanging out of my window (to cool it down) on a Winter's day!!! Honk if you do.
The solution would be a cheaper charger without the thermal circuit built in. Go into Maplins or PC World and ask them for that..... They dont know what your talking about, because I have already tried.......! Good luck
You just need to make sure to enable your phone to charge when connected to PC.
Start->Setting->System->Power->
UN-CHECK the box that said "When device is turned on, DO NOT CHARGE the battery when connected to PC"
