Dear friends...
Do i do something wrong?
My new jasjar will not charge (even if it says charging) when is open...When I close then it charges. (the indicator increases)
Do you have any idea? Is this how it is supposed to work?
It is very unproductive.
In my experience, when the device is usb connected and the screen is On, then the jasjar charges, but veeeeeeeery slowly...
mine it says charging in the 'Settings' and goes down...65%,63%...etc.
the light is orange that indicates charging as well....

The problem is that the mains adapter provides 5V at 1A. A computer's USB connection will only provide 5V at .5A, so the Jasjar only gets half as much power when it's connected to the computer. Unfortunately, this is the maximum amount of power a standard USB port can provide.
Like dherrero, my Jasjar definitely charges when it's connected to a PC, but it charges pretty slowly. If your Jasjar is using a lot of power... maybe you have bluetooth and wifi turned on and you have the backlight set to be very bright, then it's possible that the .5A just can't keep up with the power demands. When you close the screen the backlight turns off, so that gives it more power to devote to charging the battery. Maybe try to turn down your screen brightness or turn off wifi?

The other thing I just thought of is that there are two kinds of USB ports... powered and non-powered. The powered ones can provide .5A of power, but the non-powered ones can only provide .1A. Is it possible that you have your device plugged into a non-powered USB port? Normally the ones that are directly on your computer are powered, but the ones on a USB hub are not unless that hub has a seperate mains adapter. Perhaps you should try a different USB port... preferably one that's directly on your PC.

I have tried to charge MDA Pro with the mains adapter from a GPS receiver (also 5V 1A).
It doesn't work. The only explanation is that they
did something with the ID pin. I don't think
the Universal is capable of finding out how
much current you can drive from the adapter.
You are absolutely right my friend! Disabling wi-fi and the brightness...started cumulating power!!!
Thanks guys!
The situation has improved for me over the last week as the battery has become conditioned. At first mine didn't charge from USB but now it does. I've followed the recommendation of doing several full charge/discharge cycles since I got the phone.

The same should be true for Universal, but YMMV.
It's ActiveSync.. M$ changed WM5 way of connecting by modifing the USB driver with AS4, and in doing so, I think the USB is not giving the proper currents to the Universal so when it's charging using the "modded" USB port, it charges VERY VERY slow... On the other hand, if you plug it into the wall charger, it charges up in about an hr or two max...
And you DON'T have to do the charge/discharge circle with polymer batteries....

You don't have to do this once you've been using it for a while, but the manual advocates conditioning the new battery with at least one (but ideally more) full charge/discharge cycles. New batteries have to 'learn' their capacity, IIRC.
My laptop's manual said the same thing, and because the battery has a brain you need to do a full charge/discharge cycle every couple of months to re-train the battery's electronic brain with the true capacity.
Certainly my Exec now has much better battery life than it did after its first charge...
Jasjar battery
I have a different problem. I used the AC adapter to charge overnight (I had been using the USB port to excellent effect). When I attempted to powerup the jasjar it has been unresponsive.
I plugged it into the USB port, but still nothing.
Tried both soft- and hard-resets. Nothing.
Left it plugged into the USB port and took out the battery and the LED on the right side glowed red (as it would if the battery were discharged) but the unit still wouldn't respond to reset commands.
When I put the battery back in the LED went out and the unit became unresponsive again.
Any ideas?

I'm not sure that fully discharging the battery is a good thing. I saw a comment on one of the RSS feeds on Buzz Lightyears site from one of the MSDN guys who actually said that fully discharging the battery was harmful to it.

Yeah, I know what you mean. The thing my laptop manual says (which I guess applies to the Exec too) is that the device will turn off before the battery is completely flat, since the battery can't sustain the minimum voltage required to keep the basic functions alive even though there's still some charge left in it. Therefore the battery is never fully discharged, like it would be if you shorted the terminals.
I think it's the full (e.g. shorted out terminals) discharge that hurts the battery.

in the hp manuals its mentioned:
" if you charge via usb and the screen is on, the device will consume almost all the power from the usb. it will charge but at a very slow rate."
i suppose its the same with the universal

Hi.
i got a unbranded Touch Pro2 in france. the battery stand 2 days before the first recharge. but seems i got a problem of recharging.
i decide to recharge it when the phone is ON, but seems it consumes more than recharge speed. there are less and less electric in the battery, even the screen is Off, and no applications running, and all connections are disabled (WIFI, Bluetooth, Data Connection) except Phone
so i have to take the phone completely OFF, with a cable USB connected to the computer, now it is more than 6 hours, but the recharing light is always "Orange".
this is my 3rd HTC phone, and i never met this problem before. as the first recharge of TP2, is it normal to me?
thanks in advance of your help

Thanks, nearly 6.5 hours with usb cable. the light turns green, so i can start it now.
but i still not understand why it consumes more quickly than recharge. i will see if it happens only in first charge.
I saw somthing somehwhere about turning on quick charge or full charge via activesync usb, dont know what its about but its worth investegating if this is a problem for you.
I have another charging or connection problem, with all my other htc phones (5) i could use any regular usb cabel, with the pro 2 they all seem to have poor connection, have to hold the cabel in a sertan angel for it to work. The supplied cabel and the org cabel for my pro 1 works fine though. Anybody else having this issue?

same here - but applies to all my htc phone. they can not connect stability with the mini-usb of my SLR camera. in fact, there are a little different with HTC ext-usb and mini USB -- the port is a Right-angle trapezoidal, while the standard mini-usb is Symmetric trapezoidal. so that's why we should use the ext-usb cable.
same here with the usb cable ...well is not the usb cables problem but the usb plug in the phone .
concerning charging from a pc laptop.....
if i leave my phone overnight charging from the laptop and the laptop goes into standby ,even if the battery is 100% it gets totally discharged with in hours!!!! this while plugged into the laptop!!!
what a hell is this , i mean, m i charging the laptop from the pda or what!?
this is a serious bug that htc needs addressing.
please note that there is laptops that do not power down usb ports while in standby, i got one that does just that.
now my eee-pc1000h doe power down the usbs ports when going into standby.

Well i know that but that is becous they also have the headset on the same port. As far as i know you should be able to use a normal usb cabel with the device.
USB ports on a computer can only supply 500Mah of current. it seems really odd that the phone would be discharging at such a rate to deplete itself even with that current available. that would seem to indicate the 1500Mah battery in the Tp2 would only last 2, maybe 3 hours before dying if left unplugged.
when connected through a Wall outlet the phone should be being charged at 1000Mah. although the maximum safe charge rate of the battery is 1.5Amps (1500Mah.)

I have noticed that my TP2 can complain with a popup warning that there is insufficient power to charge when connected to my Dell laptop. I think it just stops charging at this point. After that it is downhill all the way!
I agree that there is something strange going on with the TP2 recharging from a USB port. I got my TP2 as a replacement for my HTC Universal. I am using the TP2 on the same port with the same cable. The Universal was very straightforward - plug it in and it charged regardless of whether it or the PC was on or off. The TP2 is very different - leave this connected to a powered off PC overnight and I routinely find that the TP2 has reached critical battery low the next morning. This means that not only does it seem not to have been charging, but it must have been "on" overnight (where the power management settings should have turned it off) in order to deplete the battery to this extent, regardless of whether it was charging or not. The battery charging light (amber to the left of the ear speaker) is on throughout.
The power management information is also odd. This AM it reports last full charge at 23:12 last night and since last full charge a standby time of 6h39m, talk time of 0 and device usage of 2h55m. However, it wasnt used at all after about 20:00 last night and power management should have turned it off after 30 mins.
It charges normally from the USB port when the PC is on.
Any ideas?
This problem happens with standard USB cables and the official HTC cable. You must have an active ActiveSync connection or the phone won't charge.
Last night I plugged my phone in while my computer was still booting. The charging light came on, but this morning I was left with 10% battery.
If you plug it into a computer without ActiveSync installed the phone won't charge.
If you plug it in and the ActiveSync icon turns green the phone is happy and will charge.
If you turn off the phone and plug it in to just about any USB power source, the phone doesen't know better, and it will charge.
I got the power error in my car last weekend. Running with the splitter, with 3.5mm into car sterio and car charger plugged in. Was running slide2play and the pop up showed up. Come to find out, later on the charging light wasnt on the phone anymore. Tried the wifes tilt 2 and it wouldnt charger hers either. The car charger died.
BUT, at the time the error came up, the charging light was up and running.

Problem with TP2 and Mini USB sync/charge cable
I have an unbranded GSM TP2. It charges normally using the HTC wall charger and the HTC supplied ExtUSB cable.
I have read that Mini USB cables should be compatible with the HTC ExtUSB port for normal operations like charge and sync so I bought a generic Mini USB sync/charge cable on e-Bay. The supplier stated it was compatible with TP2, but when I plug it in to USB port, the device charging light comes on for 1 sec then goes off and the PC shows a message saying "a USB device has malfunctioned".
The supplier sent me a replacement cable but it has exactly the same problem so I don't think the cable is faulty. I think maybe the problem is with my device.
Does anyone out there have more detailed knowledge of the compatibility of Mini USB and ExtUSB?

I think the odds are you just got a bum USB cable...the failure rate among the generic ones on e-bay is considerably higher as a rule. Do you or any of your friends have any other mini-USB equipped devices you can test it with?

That was my first thought but I have now tried three different cables, from two different e-bay sources, with the same effect. However, I haven't yet tried any of them with any other device - I'll try that at the weekend and see what happens.
so the option to not charge it is not ticked under power settings, and its set to charge via usb from advanced config and still no dice.
tried different usb ports and nothing
the led is orange, says its charging in power options
any thoughts?
Try a diffrent usb cable, some cables do not provide enough power to charge the phone. (guessing maybe they are old 1.1 cabels). But I know I have a few cables around that dont charge my phone and they also will not work with my portable external usb hard drive because they wont provide enough power for it. But they work just fine with my digital camera.
I´ve read somewhere that disabling USB charging is better for the battery life, so I have it disabled.
You've tried different USB ports, but were they on the different computers?
so i've tried different cables, different ports and 2 different PC's and 2 different laptops.
I know its not the cable i'm currently using because i plugged it into one of those A/C to USB adapters and charged fine.
I'm starting to think its my batter,
If you have tbattery installed, do u get values for all the boxes?
All mine except 3 or 4 are 0 :/
Well, you are not the only one having this problem. Mine is brand new. I started setting it up last night and had it hooked to the computer via usb. I installed a few .cabs such as google maps, myphone, and a few tweaks such as tether, disable sent notification, enable all camera modes, and manila start menu unlocker. While it was connected it said it was charging. When I went to bed I turned it off and connected it to another usb cable on another computer which is an a/c hub. I went to turn it on this morning and thought it was strange it was not fully charged. I continued to set it up a bit and take it for a spin. After a while I turned it off again and hooked it to the usb a/c charger again. I just tried turning it on and nothing was happening. I connected it to the usb again and it finally turned on, but I checked the battery level and it was at 0% and turned off. I have it connected to the a/c charger and giving it a little bit to see what will happen. One thing that seems strange is that the battery discharged more while it was off and attached to the usb a/c hub during the afternoon causing it to refuse to turn on at all. Any thoughts?

I think the odds are pretty good it's your battery. The orange light means power is going through the charging circuit, so you obviously have your settings correct.
I'm guessing you're in Austin or near? If you want to try popping my battery in it for a few minutes and see if it charges fine then, PM me and we can set something up.
the same thing is happening with mine. Sometimes it will charge, sometimes it wont. weird thing is that it only started doing this a few days ago... i know nothing has changed ROM wise, so only things i can think now is maybe the actual USB connector on the phone or the battery, but since I am getting a charge via wall chargers im not sure what to think lol
Just an update.
If i have the USB cable plugged in (and car charger to which doesn't charge as well ) after 15 min or so a warning appears saying that the current is too low to charge the device. Either closed unused apps or switch to a/c power.
I've ordered a 1800mah Mugen Power Battery. Gonna see if it resolves the issue, if it does then i'm gonna call at&t and see if they'll swap my battery for me.
I have found as have others here after reading some posts that if the phone is almost dead or battery is very low then it will not charge via the USB anymore. The orange light goes on and it says that its charging but the charging circuit seems to be protecting the phone and not letting the battery charge.
The only solution I have found, and it has only happened twice so far is to plug it into a wall charger and fully charge the battery. It will then charge via USB again and all is good. I normally only charge my phone with usb while connected to Activesync but once in a while you seem to need to top it up with a wall charger.
It is also highly recomended not to run Lithium Ion batteries right out.
How do you know it is not charging?
There is a difference in the wiring from a wall charger and a USB charger. There is a signal line in the wall charger telling it to charge at near 1000ma. In the USB cable that line tells it to limit the charge current to 500ma. That is the limit for current that you should pull from a USB port. If you are using the unit heavily, you may actually need more then the 500ma., those running the battery down possibly.
If the unit is idle, it will still take much longer to charger from USB then off of a wall charger.

If you are asking me, I know it was not charging because I also had the "not enough power to charge message" and the phone went from about 15% when I plugged it in to stone cold dead by the morning. The whole time it was pluged into a computer I have used repeatedly to charge it with. I then put it on a AC charger and it went to full charger in about an hour and a half or so.
I've just driven over 400 miles...
I was using my Desire with Co Pilot to navigate me from Scotland to Bristol...
The phone was in my phone holder which is placed in the cigarette lighter so the phone can apparently be charged at the same time as being held...
The phone showed that it was "charging" and yet it still ran out of power....
That's right.. the CHARGING phone RAN OUT of power and switched off!!!!!!! TWICE!!!!!!!!
Has anyone else experienced this? I can't imagine that this phone uses more power than the charge being applied?!
I used my Desire as GPS (with Copilot) the phone had 70% - 80% battery and after sometime it actually charged to 100%. Maybe there is some malfunction in your car charger or just not making a good contact in cigarette lighter plug. Check if charger's led lights all the time.
car chargers trickle charge so they prob couldn't keep up with the demands of CoPilot on the phone

You need to ensure that the car charger is rated at 1AMP at 5V otherwise it will as stated only trickle charge. I've heard this story on other devices. Do you have a genuine HTC charger?
Also if the device gets to warm, it will stop charging in order to avoid damage.
Thanks for the reply guys!
No, it's not a geniune one... I tried 2 different ones, both the universal holder/chargers from Mobile Fun..
So far they've both been fantastic until this little phone came along...!
Connections have been fine, which is the strange thing..
It did get hot though, so you may be right Ardsar... Any way of keeping it cooled?

Same as what others say as well. Your car charger doesn't supply enough amps to keep up.
Ofcourse it gets really hot, navigation is one of the most heavy thing you can do on the phone. And while doing that you charge it at the same time in perhaps a warm car as well.
But, get a 1A charger, not a 500mah like most are.
Same goes for hooking it on the computer, the usb port might not give enough power so the phone can drain itself when doing real heavy stuff.
Plugging something in does not guarantee it will work, you have to know what you plug in

Of course you will - USB ports can only supply upto 500mA if you have nothing else connected to the USB HOst.
Same story for me.
I got a 550 mA car charger, and battery wasn't charging but slowly discharging (about 5-10% per hour) with navi+HDSPA.
Thought, well, 550 mA is not enough, let's see the plug charger from Desire box: that's 1000 mA. Let's go get a 1A car charger.
Got this www . p4c.philips. com/cgi-bin/dcbint/cpindex.pl?ctn=DLM2206/10&slg=it&scy=IT (saw off spaces) which is rated 5V-1A.
Plugged in, started navigating+HDSPA for satellite layer, and still wasn't charging but discharging at a rate of about 4% per hour.
I'm really annoyed 'bout this, I spent 20+15€ for both chargers, I do not want to spend another 25€ for OEM charger....it's unbelivable that I'd finish to buy 60€ of chargers to find out one that do not let battery deplete.
As a final test, I'll try a different cable from original HTC sync cable included in the box...let's see.

Can anyone who has used this confirm it will manage to charge fully even while the Desire is running a satnav program?
Why don't you plug in your normal charger and start running a navigation demo or something.
Not sure if that uses as much energy, but I think it most probably will. The original charger outputs 1A.
If the socket charger does the job, but not the car charger (read: you can also run a navigation demo in the car using that charger) your car charger might not be supplying enough energy as it should.
Or you can use a multimeter and see how many amps it outputs. But the pins are a bit smallish
Tried with another cable (not the original sync one) with just power wires connected, same story: I'll try with the original wall plug charger and see if it does the same or not, as both the Philips charger and the original HTC wall charger are rated 5V-1A
It does get very hot. I used my gps for 9 hours in a row and at the end it got too hot or something and the phone just rebooted.
Still It wasn't because the battery had run out of juice it was still good.
Also it was streaming music over bluetooth at the same time.
Used Nav for 1 hour this morning on the way to work while charging from the official HTC car charger. Phone now sat on my desk, battery reporting 100%.
The phone did get pretty hot though...

FYI, not all chargers are equal. I believe that HTC devices need a combination of pins to be connected on the USB port to "tell" the phone that it's connected to a real charger and not a USB port, otherwise the phone will only pull 0.5A, regardless of the output capacity of the charger.
This always used to apply to older HTC phones, and I can't see why they'd change it, so it's quite possible that your 1A Philips charger will not charge the same as my 1A HTC charger...
If in doubt, OEM

That's what I thought, as I imagined that: I hoped that another cable I have, which has USB on one side and a 2 poles connector on the other side on which you connect various connectors, would be recognized by Desire as being a pure power cable. I wasn't lucky.
Since OEM is out for 25€, I tried with non OEM before to save some, but till now I buyed 35€ worth chargers, I'd have to stick with OEM
But now I'm really reluctant on getting OEM, since I do not want to end with spending 60€ in order to have my phone charged while navigating....I'll try to tinker some, and if I'll find out how, I'll report
I had the same problem by using a 1.5A car charger which is working great with iPhone.
As for the PC USB charge... are you sure it can't output 1A to charge the device??

USB2 specs do say that ports shall provide max 500 mA, ehnce motherboards have this limit.
BTW, here's a discussion I've found about the "cable" problem
forum.xda-developers. com/archive/index.php/t-643808.html
For HD2 (which is actually the model to which HTC CC C200 is dedicated)
I'll try to tinker with some cheap cable and see if this works.
Just been on a long run and used the satnav ( google ), and the whole time it was plugged into the cigarette lighter charger.
Despite this, the battery level was running down
Is this normal - that the battery drain using the satnav/gps is greater than the charging rate?
I used mine yesterday for about a 1/2 hr journey, was not plugged in, but batterey was down to about 30%, also seemd to use about 20mb for 15 miles, so watch your usage.

Its been discussed already, your charger is not powerful enough to charge it when using satnav, so the end result is that your charger is just slowing down the discharge. Happens when you are using 3rd party accessories.
Ah - That makes sense -- where can I get a decent one - at a decent price
I'm using the factory supplied lead and still get the same, also used to be a problem with my Touch Diamond 2 WinMo Phone, was hoping Desire would be better and it is... just... If I make sure it is fully charged before I set off I can do about 3 hours with it plugged in before it goes flat, I just keep switching it off while I know where I'm going and only switching it on when I don't! That way you can make it last until it is needed.
Another thing to check is that it is kept cool enough to charge, again, in common with my older HTC winmo phone, the Desire gets very hot while being used for GPS and this can be worse if it is in sunlight on your windscreen, sometimes this can stop it charging at all, (you can tell its in this state because the indicator light blinks alternately orange and green) I angle a vent so its blowing cold air on the phone and that seems to do the trick.
Weird thing with the Desire is that for me it shows the green charge light and battery full indicator right up till it is nearly dead... rather than showing that it is draining
I've also noticed with the Desire that even If I'm just browsing the web it drains quicker than it can charge, even using mains charger, I often get a message "the current is insufficient, please connect to AC" or something like that (when it is already plugged in)
I don't think the in car charger you use would make a big difference, the current/voltage for your cigarette lighter socket is limited by the vehicle electrics (I know mine is fused at 15 amps)

You need a charger which supplies 1A. Most 12v cigarette lighter chargers only supply 500mA
I use this one, and plug the USB cable into the "quick charge 1A" socket

Are you using Bruts worldwide maps mod? I just installed it. I ran it for literally only 5 minutes, but my phone got really hot and the battery monitor shows the app used 10% of the charge (the phone has been unplugged for 24 hours). I have a strong suspicion that this app is faulty.

Basically most usb car chargers (even 1a rated ones) are recognised by your phone as a data connection and to protet delicate computer usb circuits will only draw 500mAh where your phone requires 950mAh.
An easy mod of either the charger or a data cable will solve the problem. Your charger MUST be able to supply up to 1a.

Thats why I use the Belkin one, it detects it as a charger only and charges at full rate when plugged into the 1A socket.
Anyone else notice that our Nitro is rather fickle about the power source it receives?
If my battery is completely drained, it MUST be plugged into a higher power source than USB (so far a wall charger that ouputs 750ma works) until it gets an initial charge (usually needs at least a couple of %)...Then it will accept charging from USB (USB provides 500ma).
I can tell when it's in this "state" because it remains dead if I plug it into USB and then if I plug it into a wall charger the touch buttons at the bottom flash for a few times and then the LG logo pops up and finally a charging battery icon comes on. Considering this sequence, this seems like a functionality of the phone. I wonder if this is common, my Nexus One certainly didn't have a higher-initial charge rate requirement when the battery was dead.
I've experienceed the same scenario.

I only have chargers that operate 1.8amps and higher.
As the battery is an issue the higher the amps the faster it will charge

Well I did notice that if it was on usb...and I had bluetooth...gps, and wifi...plus running some apps and stuff...the battery actually continued to drain I think they have the usb thing as a safety measure...for some reason...I think it's odd...but meh
try a usb cable that has 2 jacks plugs to connect to tyhe computer. These cables are often supplied with external hard drives as they they require more power than can be supplied by just one usb connection.
I was also having the problem of my p-930 discharging while plugged into compute usb jack - even when screen off nad only in charge mode. I have since bought a dual plugged usb cable and it charges now. Although I haven't tried it from a completely discharged state.
my spectrum is the same way.. i can charge it with usb.. but it takes about 15-20 minutes to get enough charge to turn on

This! I only charge with a wall adapter now. I had a hard time charging it until someone here recommended this to me.
