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!!
Hi All
When I have my universal plugged into my USB on my Laptop it dosnt chanrge the device until I switch the screen off is this normal ?
Is there a setting ?
Thanks
Steve
I have the same with USB cables and several chargers (wall and car) I think it depends on the wiring.
Mostly the MDA start charging after a few seconds even if the screen is on though.
Suspect your laptop can't supply enough power through the USB port to power the screen & charge the battery.
You might want to try reducing the screen brightness to minimum to see if that leaves enough spare power to charge the battery.
Mike
It's normal. The laptops suply 0.5A but your charger suply 1A. So you sould keep screen off, or BT and Wifi off if you want your pda increases the battery level instead of decreasing......
Well as I experience the problem it is not a problem of too much load. If I switch the screen back on after it starts charging it works fine still.
sure. Because the screen on eats much power
and it doesn't when you switch it on later?
Let's se. If you turn off the screen using some program (not the pda, only the screen) the energy consumption will be less so your pda will charge. BUT if you let the screen ON the pda will spend more energy than the received by the laptop so the battery level will decrease......
I doubt that is what he is referring too. I assume he's talking about the orange led. That does sometimes not come on when the screen is on, but if you swith it off it comes on and then you can switch the screen back on and charging works fine.
I really doubt that the MDA uses more power than USB can supply. You'd have to have a lot of other devices connected to the same port/hub and seeing how this is on a notebook ...
Probably does not check power requirements all the time so you may get into a position where it can charge & have the back light on.
So one of two things will happen depending on how well you laptop was designed.
1) It will take a very long time to charge while the display is on.
2) Damage the USB power supply as the PDA will take more than the USB port can supply without damaging it.
Mike
Of course I'm not the thread starter, but what I have experienced is that it's not about the speed of charging just that the led needs to go orange and that it will not do so when the screen is on (or with a delay)
So in the end the real problem is that charging does not start when the orange led is not on (as the device remains switched on). Not that it takes longer when the screen is on. Simply that there will be no charging at all.
I have ended up with an empty battery because of this myself a few times. If I remember to switch off the device when it's hooked up then it charges fine if I switch it back on.
I have also had the same problem from a 1A wall charger. So it's not just a matter of power being available. It has to be something with wiring or signals from the charge cable too.
I'll try to see what the difference is between chargers that do work immediately and ones that only work after you switch off the device.
Some USB ports may also be designed to supply power (or a bit more umph!) to external devices. For example, one of my laptops has two USB ports; a normal one and one with a "plus" symbol designed for powering devices like floppy, or USB hard disc drives.

Completely agreed. I have exactly te same situation, whether I use the computer's USB power or a 1A wall charger. I have tried various cables with to no avail. If I want the device to charge, I must:
1. Turn off the Universal by pushing the power button,
2. Then feed the electricity,
3. Then the orange light comes on, and it is charging,
4. Then I can do whatever I want with the device as it charges.
When my Universal was new, it did not have this issue, so I do not know if a firmware update, a reset, or some third-party software caused this to happen.
My understanding is that the display backlight uses most of the power I can get a decent charge by just closing the lid rather than using the off button.

My battery was down to about 38%, charging via USB (Lid closed) charged upto about 83% after about 3hours - Not quick but good in an emergency.

Got a bit of a weird update here...
Normally, my unit does the same as above...wont charge if display is on, removing cable, closing lid/turning off then applying charge resolves issue.
Now, I used to try the charge cable first, if it didnt work, unplug, close lid, apply charge again.
Past few days, I have been inserting the charge cable in and pressing power (lid still up)...at this point it doesnt charge (does if you close lid instead of pressing power), but if i now close lid and re-open lid, the screen comes on and so does the charge..at the same time ?!?!?! :shock: :shock:
I have tried this process and left lid closed for few mins before opening it, but the charge starts when the lid is opened not closed.
And also, if you get unit charging, then remove charge, you can apply charge again in any power state (within 3 mins) and unit will charge instantly?!?!? After 3 mins you have to mess about with power and lid...
So, is the charge linked to the lid closing, or linked to a change of status of the units power??? :roll:
EDIT: ahh haaaa...the 3 min thing was cos my power down timeout was 3 mins :wink: so I did some testing;
1. lid up, screen on, backlight on - insert cable (no charge), press power (no charge), close lid (no charge), open lid (charge)
2. lid up, screen on, backlight off - insert cable (no charge), press power (no charge), close lid (charge)
3. lid up, screen off (from timeout, not power button) - insert cable (no charge), close lid (charge)
4. lid up, screen off (from power button) - insert cable (no charge), press power (no charge), close lid (charge)
......helpppppppppppppppppppppppp :shock:
Ha, ha, I guess these machines are becoming so complex that they start to become really "alive"

how many secs elapse before you close lid in these experiments? it is normal to wait a couple of seconds before the charge led comes on.. sorry if this was too obvious!
other ideas: the contact is not good, and when you move the unit it could get better.
do you use the usb sync cable to charge or wall charger? i use the latter. supposed to be much better.

I have tried these test with USB from laptop, USB from PC, USB from powered HUB, Wall charger and Car Charger...all same results. And I did wait for several seconds before closing the lid, in the vain hope that it would start charging...sighhhhhhhhh.
Only difference I have noted...and this may point to a possible app to fix it...if you use USB cable from PC/Laptop with ActivSync installed, it starts charging more reliably ?!?!? Kinda points to this being a polling problem within the units software ie: activsync connection sends a request which prompts device to check port status, sees power and starts charging...whereas a connection with only power doesnt force a poll. Problem here is, laptop/PC direct connect (as opposed to a hub connection which can cause some problems) is only 500mA power...wall charger is 1A...so charging time on a USB connection is VERY slow.
Anyone know of an application (or can write one) to change polling frequency on device??? Or maybe there is a registry setting that covers this?
*prays on knees* :lol:
You have the problem with the standard MDA Pro charger too? Or do you have another wall charger?
Between the different chargers that I have I see great variation in the time they take to start charging. Some start immediately, some will take a few seconds and some will never start if the device is on (or screen is open) Each charger behaves quite similar every time though.
In my case I doubt software would help much. I actually have 2 MDA pros ( (it fell and the screen broke so I got a new one) They each have a different rom and I think the behavior between them is similar. Although I don't recall ever having the MDA pro mot charge in my car as it did with my old machine.
I'm still guessing there is a difference in a signal line somewhere that the MDA pro detects the charge quicker.
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.
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,
I have a navigation software on my x10. everything works fine but it seems that this programm needs so much battery that the charger can´t charger the battery.
With navigation turned on and charging the battery is still getting lower and lower.
I have a self build car charger in my car with 1000mA but it seems, that it´s not enough.
Have you any suggestions, how to solve the problem? Is there an app to change the cpu usage for the navigation to e.g. 60% instead of 100%? Or is this only possible with rooted phones?
Thanks.
Same Problem over here.
My only solution --> 2G instead of 3G and turning off W-Lan.
In that way (with GPS and Bluetooth active), the phone at least charges very slowly and doesn't drain the battery.
I had turned WLAN, BT, 3G off. But my battery was still not loading... Maybe I have to switch from 100% Screen brightness to automatic. I will try it the next time...

But the charging symbol shows up?
Did you shorten the Data+ and Data- Lines on your selfmade car charger?
I guess, you build it, like i did:
I took a 12V cigarette lighter to USB adapter.
Then I broke that thing apart and soldered a (micro) USB cable directly do the USB jack.
To make it working, I had to shorten the inner two lines.
Otherwise, the phone didn't charge at all.
Then I glued / taped / bubblegummed the whole thing an threw it behind my radio
Or did you build an other solution?
I build it myself, not broken a charger, and yes, it´s working (data is shorten), but it´s not enough to load the battery during navigation. If I turn navigation off, my battery is charging as usual.

Nice one
Uhm.. what about rising mA a little further?
I've no clue what max. should be.
Probably you know?
I've also seen USB Chargers with 1500mA.
But I dunno, if its a good idea.
Phone + Battery would also heat up a little further...
Another Idea:
Maybe there is a couple of Apps running at full load in the background?
Take a look around in this forum.
Especially at the "helix launcher" and the "battery life issues" threads.
You can also download the App "SystemPanelLite".
With that one you can search and monitor the running Apps and their CPU consumption and so on.
With "Task Manger" (the one made by Rhythm Software) you can set up a auto kill rule.
Hope, that helps...
I have also tried to charge my phone with my car charger left from Omnia HD and the phone is not charging ??? HTC Desire is charging but X10 is not. Can someone tell me what could be the problem ??
Tnx
@damirbusic
The Problem is, that the two Data Pins (2 & 3 - the two middle ones)) must be shorten. Then the X10 is loading...
@McKebapp
I´m tried it with helix launcher and have some applications auto killed and all tasks closed. But it's still not enough.
It´s possible to charge the Li-Ion Batteries with 1500 mA. That will be my last solution. Don´t want to charge it with 1500mA due to overheating, specially in the summertime...
I don't have this issue at all, weird

@UserX10:
Uhm... that is strange after all...
Which Navi-SW do u use?
I use "Sygic" for onboard navigation.
Normaly I use Sygic, too.
I tried Navigon, too, but the same result.
Both Apps draining the battery more then the charger is loading...

Really Strange...
Which temperatures do you have to deal with?
My last Idea: Maybe some overheat protection, that limits the charging rate?
By my one is the problem defently the temparatur... when i hold me phone in to the airstream from the aircooling then does the phone charging works. If i let the phone just on the right side of me on seat the it doesnt charged. But the symbol on the phone say the is currently charging... with the tool batterygraph can i see, thats isnt true...
aso i can reconized that the phone is hot.. realy hot.. extremly when the sun does shine on the phone.. the only solution is for me, to hold the phone from time to time at the airstream or i let the phone down in to the footweel, where does the sun not shine and a airstream flow around...
The akku is the warmest thing. without the cover, it works better.. i thnk the akku has around 45°... when is hot..
tested with navigon..
Hm... that´s possible. I will try it the next time with holding it in the airstream... Maybe that´s the solution.
I've got an windshield holder (dunno the correct English word).
While I'm driving open with my convertible, I set the airstream to the windshield (demister setting, but without heat), to cool the Phone a little down.
(If the Car is closed, I usually drive with activated A/C at 19°C - 23°C depending on my mood and the frozen girl on my side )
My Phone never exceeded 40°C.
So, this really may be the solution.
BY shorten the middle 2 pins... do you mean "short circuit" by joining the pins together in some way.
I have the same issue - I have the car charger from my old samsung omnia but it doesn't charge the phone and using any navigation software drains the battery very quickly
Jepp, short circuit the both two middle pins, then it will work.
For information: I tested today the charging with power supply.
780 mA is the maximum what the X10 takes. Tested with empty Battery (in Idle Mode and Apps running + WLAN + BT + GPS). Same result.
So a 1000 mA charger is fully sufficient.

Thanks for sharing your knowledge.
Great work!
What's your opinion about your battery drainage?
Do you really think that the phone, running at full load, will suck more than 780mA to prevent charging?
Or is it really an overheating prevention?
Something I realized today:
I drove around for about an hour today.
We had 31,5°C today.
The phone was placed in its windscreen holder directly facing with its backside to the sun.
I drove with closed top A/C at 23°C.
At the end, when I was at home, the App "TempMonitor" showed me 56°C at the battery, that still was charging.
On weekend I'll try pushing the limits a little higher.
Empty battery + Navigation + open top without any A/C.
I hope my phone doesn't melt away
