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.

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.
Had my Ameo connected to may Laptop via USB for several hours without much usage.
However, when checking battery status the battery went even worse. I had only 20% remaining battery power.
Update: Battery power went to 10% now while connected to Laptop...seems to me that USB power is insufficient to charge the Ameo. That means it is impossible to work for a longer period with connected Ameo because the battery runs out of power !!!!!!
Who has made any other experience ?
Dieter
I see the same issue, although not as severe as for you. When I'm connected through the USB cable I don't gain nor lose battery power. I have had it connected for mopre than 12 hours in a row and see no change in battery power.
Not sure how you could resolve this.
Must be the case. Mine does charge (USB 2.0 - how 'bout yours?), but, it can take 12-15 hours or more to charge from 30% to 90%. Never seems to get to 100%
Yes me too. it's such a dramatic different when comparing it with Universal. Much faster charging.
I think this is mentioned in some other posts, wonder if there was a way to sort this out?
It appears the Athena uses more power than the USB can replenish. Strange. Ive had a universal and alot of other HTC devices and they were fine like you said.
mmm! strange
May be by using a powered USB Hub would make it charged. I'm going to try it tonight and will post the outcome soon.

I was thinking that would be the solution but I don't have a hub.
If it works with yours I might need to buy one.
rating
The supplied adapter is 1A, USB nominal is, i think 500mA so half the adapter current. On the two pc's I've tried mine on they sustain but not really charge the athena or if they do its a very slow charge.
With backlight up and wireless on I don't think they even keep pace.
From wikipedia:
"The USB specification provides a 5 V (volts) supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.35 V between the +ve and -ve bus power lines. Initially, a device is only allowed to draw 100 mA. It may request more current from the upstream device in units of 100 mA up to a maximum of 500 mA."
After charging using powered USB Hub I can confirm that my device does get charged. The result is better than just using standard USB port, but worse than using the supplied adaptor.
The power consumption is because of the MD and the screen (which is much larger than on the Uni, hence the slower charging with the same amount of power).
You can't turn the MD off. However (if you don't have a powered hub), you can turn the brightness of the screen down whilst on external power and, hey presto, it will charge faster.

Yes, this sounds like a problem we had before with the universal. Turning off wifi and backlight after a few minutes of inactivity; turning brightness down to very low (next to lowest level) on external power, improves it. In fact, my ameo is now fully charged on usb. Not very fast though.
I did get a scenario using TTN 6 when it did go off in the car. The battery charger didn't seem to be doing much good. So for long distance navigation, I'd recommend fully charging your device before you leave.
I have a Veripart Car Charger mini usb that I use in my car when I use TomTom. I have the brightness at maximum, UMTS on, Push-mail on and I make phone calls. And still is has more power when I reach my destination.

May be you should use a better powered USB Hub (1 A perhaps).
Using a 6V 2100mA...
However, this may be depending on the usage of W-Lan. Seems to me that W-Lan needs a lot of power when switched on.
Wit W-Lan "On" there is nearly no charging at all.

How about charging while turning off the W-Lan? No charging at all too? Mine get charged. Only it's not as good as compared to using supplied power adaptor.

MD is MicroDrive.
But I think the Microdrive should sleep itself when unused though. I would be surprised if MD in Athena is continuously spinning.

Hi commumity,
was using my Ameo today in my car. BT and phone activated, screen maximum brightness.
I have a 12V / 230V converter installed providing 160W continously. While using phone and contacts throughout the day, battery power dropped more and mmre though my device was connected to power supply. In the afternoon it ran out of power starting with loosing the connection to vodafone.
Who has similar experiences, who has a better way of charging in car?
best regards

My old car charger which works fine with all my old WM devices does not supply enough power for my Ameo.
My Brodit powered holder does.

I second that. This has been discussed numerous times - you need to check the ampage of your charger. If it's niot supplying enough, turn the screen brightness right down.
Well i guess its time for a little electrical networks lesson.
this phone consumes, under typical use about 300mAh, so if you have the screen on bright and the phone on with bluetooth your going to be using more than that and don't forget you still need to charge the battery and to top it all off your device will start to get hot and nothing kills a battery more than heat.
Solution: you need to make sure that you get a car charger that has an output of at least 1A... remember it will work with less but it won't charge as fast. usually but not always, you can find this information somewhere on the charger.
hope this helped
Output of 1A is one thing, but it seems that HTC devices (the Athena for one) more ways for charging. The orignal car charger from HTC does power the device fast(I have the charger for a few days now and can confirm that). There is also adapter cable available that allows fast charging. See the following post and post. It looks like the original HTC connectors use different pins on the connector for fast/powerfull charging

Yes, you're right. The original car charger does charge very well my Dopod with the screen turns to maximum, phone, bluetooth and GPS all are turned on.
Would anyone please care to post a direct link to a fast 1A car charger in the UK? I tried looking at the HTC ones at expansys but wasn't sure which were official and which weren't. Thanks
Yeah, a link for a good charger in The Netherland would be apriciated as well!
Thank in advance.

We (noordwyk & Me) managed to put together a Portable Charger for the Diamond. I have attached some pics:
noordwyk will soon post the diagram
Sounds cool anychance of some more info: Like what you used and a diagram to show how it's wired? Please.
When i get time I shall upload a graph
For everyone without soldering skills - there are plenty of portable external chargers for sale, even one from HTC:
HTC Battery Bank BB G300
i've bought a couple of portable chargers. Neither of them worked. In bothe cases i plugged them in and my diamond showed itself as being connected to a power source on the task bar. The light ring pulsed in the charge pattern also. However after a few minutes of "charging" once removed the battery level is lower than when i plugged it in. This is the case whether i had the diamond on or off when charging. Chargers work fine using different adaptors on other none wm phones. The thought i had was that the chargers were outputting enough to power the charging circuit but not enough to charge. This in turn is draining the battery. any thoughts ppl??

Portable chargers and HTC don't go together. You MUST switch your phone off to charge it otherwise the PMS will get confused and keep changing power sources like External > Internal > External > Internal and so on. Just like a light switch when you turn it on it takes more power than just leaving it on for 10 minutes. Portable chargers have a charge rate of ~250 mA which is 1/4 of a Official HTC Charger.
Conclusion: If you want to use a portable charger ONLY use it after turning your phone off otherwise its USeLESS

Basically what i thought then. I must be getting particularly rubbish ones because they dont even work when the phone is off. I gave up on them a few months ago and just bought a spare battery and charger. Quite cheap off ebay and a battery is a smaller item to carry than a portable charger.

Well its true in the UK
Shouldn't be too hard to build. Take one of these (high efficiency!), solder the 9V battery adapter and the mini-usb cable to it and your're done. Only thing I worry about is the capacity. You get NiMH 9V cells at approx 250 mAh. Given the battery voltage is 9V, you get a total energy of 8.1 kJ stored in it, which translates to 450 mAh at 5V (input voltage of device). Given that this back-of-the-envelope calculation does not take conversion losses in account, you can be happy if you get 20-30% charge out of it. Maybe you could wire several 9V batteries in parallel so you get more charge out of it. Which I am gonna try out right away .

No. MythBusters tried it out. Turning on an incandescent light bulb (60W I think?) uses about the same power as leaving it on for 17 seconds. Fluorescent light bulbs didn't use significantly more power to turn on.

Ok...
The only problem is that my Diamond seems to use more power than what is provided by the car charger... So the car charger limits the discharge, but that's all.
On my old prophet, I could have used GPS for days (using a bluetooth external GPS of course).
It's a pity the diamond is not as power efficient.

I agree with you. A fellow XDA member posted somewhere here that he started of with 100% for a 6 Hour journey using his diamond and when he got to his destination he said it was around 30% left!
It's not too hard to build one, as soon as I remember, it's adapter (for the battery), 5V regulator and a female USB (it's easier to find, you use your sync cable and you can charge other things, MP3 players, portable speakers etc.).
Am I right, or you have different design.
Also, you can use 4 1.5V batteries, I've got few 1900mAh of them, so they should last longer. Also, I think the regular 9V battery is bigger than 250mAh.
Well i soon will be updating my E42M website with this years invetions so visit it when you can

When the phone is charging, and i try to use touch, i notice the input is jittery- try pulling down the notification bar on the top, and holding it half way down the screen and looking closely. Scroll with lists and hold your finger in once place - does the list jump around slightly?
Is it just me or everyone?
Maybe I should not use my blackberry charger at work! I will test with the samsung charger at home (the output voltage is the same as the samsung so it shouldnt matter!)
I feel you man! Had the exact same problem with the original Galaxy (i7500) - my unofficial charger made it impossible to type anything: heavy jitter.
Ccl: find a charger with the exact same specs...or just use the official one / or usb cable.
No problems here. typing this using swype While charging and its faultless!

Well it's better than my Desire which gives you a static charge or electric leak somewhere when charging and you touch the metal bezel.
i read something about this issue in the user manual, the PDF one somewhere in this forum
look it up, and read the battery or charging section
Have the same exact problem with my Original Galaxy S when using a "not-samsung" micro USB charger, with the obvious difference that my screen became completely unusable not just "jittery", it didn't respond to any touch when charging it with that charger.
Use official charger and it'll be fine !
Yup it is mentioned in the user manual, it said the touch screen may not function well due to an unstable power supply. I guess it applies to all touch screen phones.
thanks for the input guys and hopefully this will clear it up for anyone else confused by this.
Last question - am I damaging my phone by charging it on my blackberry charger?
Only one I have at work which is why I ask,
Thanks.
While I cannot confirm whether it will damage the SGS II or not, I can certainly say that when I used to use BB Chargers to charge my Motorola Razr among others that were Mini USB, they ended up ruining the battery life and giving me false readings about the percentage left.
Personaly I would not take the risk for my beloved 600€-phone

I dont know - I just tested and the same thing happens with my old Samsung Galaxy S 1 charger . hmm.
(my phone works just fine.(only while charging via pc). it does jitter when you charge it through mains.
voltage converter?
Since I live in the US and ordered a UK model, will i need a voltage converter + plug adapter for my charger or will a simple plug adapter work just fine?
This phone has capacitative touch screen, and I believe this works on the principle of changes in electric field upon bringing a conductor(read "finger") near the charged display. I suppose during the charging process the leaked current is interfering with this electric field causing those above mentioned problems. Might be substandard charging adapters?
Same problem on my Dell Streak! A good thing to test it is Swype! The line your finger makes when typing goes all over the place!
