I have just found that my XDAII is charging via USB -- is this a 'designed' function ?
I took my power cable home and left it there and docked the XDA in the morning at work, to my suprise the screen brightened (as i have it set to dim on battery) and it is charging !! BONUS
Now I can leave the power cable at home (I sync via WIFI at home anyway)
---DELIGHTED----
yep that is designed, a benefit above the old ipaq
BUT be aware, it will NOT charge the additional battery slot in the craddle, you still need the charger for that

Yes. XDAII can be charged by USB - you do not need to use the "power cable", USB itself is enough. And surprisingly: USB charging is fast enough.
usb is 500mA pr powered port
a powered port is a port in the pc or a port in a hub
if the hub is not powered and you have alot of other stuff
the xda will get less power and it will take longer
500mA is ok current to charge with imho
Well is saves buying another charges. as you need definately two of them, one at home to cover the weekend, usage and one at work, to cover the dailly job :lol:
Are you really sure that it is charging if the battery is under 30%? For me with older firmware (1.52) it can charge only if over 30%! In other cases it shows "Charging" but really it only faster discharges because of brighter backlight.
Is this behaviour fixed in 1.60 firmware?
I can actually charge from compete NILL, :lol:
charge vis USB
I find my xdaII charges much more slowly by usb alone.
From my laptop it took 2 hrs to charge from 40% to 100%, with the power adapter it takes about 30mins.
USB charge but can´t sync
Hi,
Can I use XDA usb cable on XDA2 for sync and charge? Is it the same cable?
Yesterday, I suddenly stoped the sync and I cannot perform it again after that. Could you help me to solve this problem?
I am on the road a lot and don't want to be carrying the HTC charger with me. For my Treo, I had a foldable USB AC adapter (.8A and 5V) to which I plugged in a Sync and Charge cable and it did just fine.
After reading all the comments about there being two ways to charge a Tilt - fast and slow, I decided to test out a retractable USB data cable with my USB AC brick. I set the option in Power to "Not charge the battery when connected to the PC." and plugged it in. Nothing. I then unticked the box and sure enough, it started to charge. As I was at 70% of the charge, I expected this to drag on, but it didn't. It took about 1 hour and was fully charged.
I'm still a bit worried about charging this way - the description of the Lil Sync cable for the Tilt says that while it might work, under certain circumstances it won't if your battery is below 30% of a charge. Has anyone seen this happen? The last thing I want is to go away for a few days and be stuck with a dead batttery.
Do I need to pick up a special cable from ppctechs or boxwave just to charge? Should I just carry the supplied charger?
I always charge my kaiser just using the sync cable and it works fine even from a flat battery. there seems to be absolutely no need to carry an AC adapter around when you can just connect it to a computer to charge.
Thanks Spooki. Just curious - how long does a charge usually take when you charge against a computer's USB?
it seems to take roughly twice as long as a wall charger but i work with PC's all day so doesn't really bother me, much easier than carrying a charger around.
the first battery charge on the HD is supposed to be a 8 or 10 or 12 hour charge? or on its not necesary
also the time used to charge it to the pc via usb cable is same as if ud plug it in the electric socket?
how long dose it take for u to charge ur phone.....
mine had 4 lines out of 10 and after 3 hours of it beeing conected to my pc and not in use its still got 4 lines....
opinions seem to vary on how long for 1st charge - personally I left mine on (mains) overnight, but that's just because I've had mobiles since year dot, and you used to have to!
But charging via PC doesn't seem to work as well as from the mains charger - depends a lot on the PC and how much juice it kicks out, some are a lot better than others.
Modern phones/batteries do not need "overnight" charging. My Touch HD even came with a little note saying you don't need to charge for 16hrs/overnight. Just charge until it's full...
Better to charge with wall socket because not all USB ports provide enough current. Some can't charge through the USB port while some can.
I can charge through my notebook but it takes a lot longer than the wall socket.
thanks bouth of u for the fast anwsers....
When I set WiFi settings to max performance, my HTC HD will not charge at all, actually it will loose charge during night, display is off, just WiFi, GSM and GPS is active, connected to provided wall charger. Back side of phone is really hot, I measured over 54°C
Problems charging.
guys(and lady's) Just got my HD. been running it for some time to drain the battery, while on my laptop the battery starts charging. I wanted to drain the battery to give it a good charge afterwords so I turnd off the option of charging while unit is active( in batt. menu) but When I got to 5% batt.cap. an tried to charge the unit (batt. option enabled again) it doesn't charge. now my batt. is empty and can't get in the phone. while on power my battery charging led gives a couple of seconds of charge indication then it turns off.
Any suggestions or is my battery dead. (charging unit is oke, and when on power the HD does give sufficient power to the battery (measured with mulitmeter) thx guys edit - Als when on power green and amber lights blink.
Could that be that your battery is too hot ? There is some safety protection that prevent the batyery to charge when it is over a temperature level.
battery not charging properly
My touch hd not charge the battery more then 50% i change the battery but same as before.
any suggestion

Touch HD Battery Charging Problem
The rom i am using is Energy 3 Rom
and try to use both sources wall socket and pc usb both are same.
if i charge the battery on usb cradle and put the phone it shoes 100% but after some use of the phone the charging start again and never show's full even left it over night.
Best regards
Not sure what's going on there,but try draining the battery to almost empty each time and then turn your phone off before charging it. Do this a few times and see if it helps. Mine took about a month beforeit came good.
Dear samlives
Thanks for helping
I will try it

HTC Touch Battery Charging Problem
I got a solution its not 100% but for time being its working for me.
Long press the power button and put the device in sleep mode.
All Done now charging 80 to 90% quite better then before.
Thanks a lot
This morning I almost got a shock because my X1 stayed black and seemed to be totally dead. Luckily I soon figured out that the Battery was empty, no currrent left on it to let the device even blink. But what happened? When I went to bed yesterday I connected it to the USB cable and left it charging! Everything seemed the same as all the times before. What may have caused this?
Only things that were diffrent from my usual charging procedure:
The Cable were connected to the PC USB Slot.
I shut the PC (laptop in this case) down but the USB Slots had still power. The charging lights of my X1 followed their normal pattern.
Normally I unplug the power cable from PC to prevent the USB Slots to have power. Because my USB harddisk keeps rotating while having power from the USB.
Normally I charge the X1 directly from the power outlet. X1 turned off.
So this time PC was off. X1 was off. USB Slots still got power. X1 connected with USB Slot. X1 seemed to charge normally.
Well, the result was that my X1's Battery was totally empty the next morning. Obviously instead of charging the USB slot drained of the whole battery power! But note that the charging lights were active as normal and the Battery was still warm in the morning.
Perhaps this helps others to prevent such issues.
you are crazy if you:
1. charges from laptop
2. from powered OFF device
you can repeat this case endless - xperia will be drained

Don't charge it in standby mode, how stupid is that?
What? I don't see any reason not to charge it from a laptop. Even if it's powered off, as long as the USB ports have power (mine has a BIOS setting for this) there is nothing wrong with that.
Also, what does it matter if you're charging the phone powered off or powered on?
On an interesting note, however, the same thing actually happened to me last night.
I plugged the phone into the wall socket to charge it (battery was at about 20%) and I actually saw the battery percentage rise as I was still using the phone. I turned it on in the morning (from standby, not powered off), and as soon as I pulled the power cable it went dead as the battery was completely empty.
I have no idea what might have caused this, and it hasn't happened to me before.
Next time dont power off ur X1,
if same happends then your battery is suffed.

1) This was accidently
2) Why? I dont like it when mobile phones are on standby while I'm asleep. Charging the device when powerd off should make absolute no difference? Worked everytime but the one where it was connected to a powered of laptop.
Why will the Xperia been drained?

What does this BIOS setting say? I assume that my USB slots had too less power when laptop is off. But its very strange that your Device got drained while connected to the wall socket and in Standby mode. Maybe my USB slots were not the cause? Weird ...

It is weird. Since your phone was off I don't think it would use any of its battery power.
I have a ThinkPad, and IIRC the BIOS setting is something like "Always On USB", in the USB settings. With this turned on the laptop will power its USB ports even when turned off, as long as the laptop itself has the power cable connected.

from powered off PC, when power on usb enough to wakeup PC or feed LEDs,
but not to charge another device. in that case power go into the weaker side, means from x1 -> pc
I had this problem too... seems after hard resetting my phone one time, one option was different to normal after I hard reset,
Click on the battery icon at the top of the screen
Theres a tick box, that says:
"When device is turned on, do not charge the battery when connected to the PC."
this was ticked for some reason. Unticked it, and all was fine.
Try it
I noticed this happened to me too for the first time, after i put in the wall charger and the the phone seemed to charge, i found it completely dead after 3 hours and the battery was warm, running a vanilla R1A

Also I think for the X1 to charge- it requires activesync. from my experience, when connected to the pc- without activesync, the X1 would indicate charging- but never actually gets charges. Hence when your notebook is off, activesync obviously wouldn't be running-> no charge either.

I assume a turned off PC would only power its USB port power pins and wouldn't respond to any transmissions on the data pins. So to the phone it should look just the same as if it were connected to the wall charger (just probably with a bit less power).
Also, when I have my phone connected to my laptop through USB Internet Sharing it does actually charge (it doesn't connect to ActiveSync when using Internet Sharing).
The device should charge in any USB mode as the USB port's power pins supply power regardless of the protocol used on the data interface.
Does the X1 have no safety feature that does prevent the battery from being drained?
In my case I assumed it happened because of the USB Port had too less power. But when you turn off your PC (+USB power) and let the X1 connected it would still mean a movement of current from the X1 Battery --> inside the PC as long as they are not on the same potential. If the PC is earthed somewhere (for example connected to the wall socket) the Battery would be drained out totally! They never get to the same potential as long the Battery has power.
As jjm34 mentioned, if the PC is on and USB slots powered normally the X1 should charge in any case.
Maybe this is not the real cause of the problem. People are reporting that the X1 got drained while connected to the wall charger! That's really weird. How can the battery being drained by this? Any suggestions @Ethermind ?

It could be:
It's drawing power FROM your x1 to provide power for laptop internal components.

Mine has. Put it on the wall charger and the charging symbol is there. It reaches 100%, the charging symbol disappears and it shows 100. Then in the morning it's at 90% even though it was still on the wall charger.
I've not left it plugged into a 'running' pc or laptop long enough to see if the phone runs off the battery after it's reached 100%, but it shows the same symptoms. Charging symbol until 100%, then it changes to 100%, no more charging symbol.
Even MSVC stops reporting '% & charging', just reports the % level once it's reached 100%.
I made 2 observations :
It seems the X1 need usb data pins active to charge the battery. The wall plug has something enabled to give power to the data pins (by the way, the wall plug can charge an iPod or an iPhone, it works perfectly). I tried using a cheap wall plug bought in china, no way to charge the X1 or my iPod as there was no power on the data pins. So when connected to an off PC, I'm not sure what's happening. If someone can give a try to analyze this with a multimeter, that would be nice.
It seems also the X1 stop charging after going to 100 %, and won't charge anymore unless you unplug - replug it.
Thanks for your contribution.
Maybe there exists a real hardware failure.
Normally the X1 should charge until the Battery reaches the 100% level. Then there has to be a switch that prevents the Battery from getting overloaded which is good. So charging stops.
The switch blocks charging until you unplug the device once it has reached the full battery level. Thats ok, too. You should not loose much Battery after a full charge and with a device on standby or powered off. And it prevents the Battery getting reloaded at high percentages. Otherwise it would start charging at 99% and stop again at 100 and so on, all the time.
But now assume the switch has sometimes, somehow a failure.
Instead of preventing current to get inside the battery it enables that current can flow into the wall charger.
I do not expect that the current flows into the power outlet. Maybe it gets "lost" in the current transformer that you've plugged into the power outlet (Thats the one you plugged the USB cable in.). Lost means it simply gets warm / hot.
Measuring the current with a Multimeter would be a nice proof. If someone has the technical knowledge and qualification to disassemble the current transformer and the USB cable, you have the go .
I haven't tested it, but I doubt the current flows back into the charger, or back into the USB port on a laptop / pc.
But how does the Battery discharge then? When there is no current flowing out it will stay loaded. (it goes like d(q)/dt+div(j)=0 )
Did you all charge your phone while it is on (standby)? I noticed the same problem when I charged my x1 while it is standby. When I pull the plug from my laptop (I used my laptop for charging, laptop powered on), I get 90% battery life. It seems like there is a switch to cut out the power input if the battery reaches 100% and power the phone from the battery.
Try to charge your phone while it is off. I did it yesterday, and it had stopped charging even before I unplug it from wall output, and I got 100% battery life.
Btw, this is not confirmed yet... it is just based on my experience...
I always suspected that when the Diamond2 is plugged into USB, that the phone continues to run off battery and is simply re-charged. This means that if you have programs running that are consuming the battery faster than it trickle charges, it was possible that it would never fully re-charge.
This situtation was made worse by ActiveSync which keeps the phone alive when in the cradle. If my phone was pretty discharged in the morning when I put it in the cradle, it often never re-charged. I had got into the habit of turning it off so that it re-charged.
WM6.5 has sort of confirmed this. Firstly, it now does re-charge when in the cradle when still on - I assume this is because power management is improved in 6.5 so that it doesn't consume as much power in idle.
But the original suspicion (i.e. doesn't run off USB power then in cradle but still uses battery) was confirmed today when a message popped up saying "Battery is discharging faster than it's charging, please close down some applications".
Nice
Cheers, Rob.

USB2 spec is nominal 5V and 500Mah.
But if you use other USB slots then the available current will be reduced.
If the battery charge has been drained below a certain level then the charge circuit will struggle to recharge as well as power the phone.
Attempt to charge as often and for as long as possible, whenever you can preferably with a dedicated wall charger or in car while mobile.
I had a similar problem with one of my old phones. I had alot of devices plugged into the mainboard, so there simply wasn't enough power left to charge the phone battery.
I solved the problem by getting a USB hub with external power supply. Didn't charge quite as fast as with the wall charger, but still enough to keep the battery at full charge.
I'm not sure you got the same problem, but it could be worth a try. Perhaps you should unplug all other USB devices and see if it gets any better first.
>USB2 spec is nominal 5V and 500Mah.
This isn't USB charging - when in a cradle, it's like charging from the mains charger. The cradle has it's own power supply.
I haven't got a problem My post was just to confirm that a) the Diamond2 always runs off the battery even when plugged in to the mains and therefore if you are running programs that drain faster than it's charging, your battery will never fully recharge and b) WM6.5 now monitors this situation and warns you that it's happening so that you don't wonder why your battery isn't fully charging or takes ages to charge.
The reason it's an issue in the cradle is because ActiveSync prevents the screen for turning off and therefore one is at risk of the above, i.e. discharging almost as fast as it charges. Turn the device off in the cradle and it charges as fast as when using the mains charger. Best charge speed overall is with the device completely powered down.
But WM6.5 has also reduced the power drain when in the cradle, turned on and when ActiveSync is running. In WM6.1, it just about recharged when in the cradle for 8 hours. With WM6.5, it charges in a morning.

You didn't say anything about a powered cradle!
That setup should have no trouble charging and powering the battery and phone. If it doesn't then suspect the power supply especialy if it's third party. There should be no need to charge when off.
My laptop will quite happily charge and power.
I have problem with charging with this Error:
the charging is not enough for device power consuption. Please shut down unused applications or switch to AC adapter

When synchronizing or only by conecting to PC or notebook
It's not an error as such - all it means is that your Diamond2 is discharging faster than it can charge. The reason it tends to occur more when connected via USB/Sync is that a) the charge power via USB from your laptop is lower than using a dedicated charger and b) ActiveSync keeps the screen on thus drawing more power.
So hence the suggestion you should close some applications to stop them running thus drawing more power. Of course, the biggest draw is probably ActiveSync and the only way to stop that running is to turn off the phone when in the cradle.
That said, I've found that WM6.5 is much better when it comes to power drain when in this mode and I've only had that message once.
