Hi,
I've had my XDAII for just over a year and I think the battery is starting to die!
I seem to be having a number of problems:
- When I put it in the cradle it doesn't seem to charge unless the PC is switched on, even though I have the AC Power Adaptor connected - it didn't used to do this.
- When the PC is on, it says it's charging but seems to be losing charge very slowly. It's been on 87% for a while now and just dropped to 86%.
- The backup battery seems to die very quickly. It only goes up to 50% and if I take out the main battery for even just a few minutes it goes down to 25%.
- Also, the PC doesn't recognise the XDAII 9 times out of 10. If I keep taking it out of the cradle and putting it back in it will eventually recognise it - but most of the time it just tells me a device connected to the PC has malfunctioned.
Can anyone help? Is it a problem with the battery or perhaps it's just the cradle??
Problem is, I've lost the adaptor that enables you to charge the XDAII without using the cradle, so I can't test it.
Please help!!
Thanks
you can try taking the batt itself out and charge it for 24hours in the cradle and put it back in to see if it'll help
otherwise you may have to buy a new batt
Hello,
I bought a second hand Qtek 2020. The seller didn't have a cradle, but he gave me a USB sync/charge cable and a AC plug with USB slot. So I insert the one end of the cable to the PDA, one end to the plug and I recharge.
The device came with 90% charge and I could easily charge it to 100%. Today, I ran it down to 0% and now I can't recharge it!! Every time I turn the device off and plug everything in, it starts to recharge. The led on top shows red. It charges for about a minute and the device wakes up. The red light turns yellow. It says on the screen that the device is still charging but the meter is stuck at 0%!!!
I've been trying for hours but I can't even get to 1%. Maybe it would be better if I had a cradle but that's not an option now. Besides, it recharged beatifully yesterday.
I have a feeling that if I can stop the device from waking up automatically when charging, I can recharge fully, but I don't know how.
Any help will be very appreciated.
Update
Here's a quick update. It's gone from bad to worse. Now I only have a blinking red light and the device doesn't come on at all!!
Any advice please?
Have you made sure that the plug is connected tightly to the PPC? If the charge isn't being held, then the battery might be the culprit.
li-ion batts have a limited number of times it can be recharged before it's lifespan is over
maybe your batt's time is up ?
Follow-up
OK. I bought a new battery and everything works fine now. So if you're having a similar situation, a new battery may solve your problem too.
same problem
I had the same problem as you. When the battery was on 30% to 90% it could be easily charged via USB from PC or via usb adapter. Once the battery fall under appr. 20% I was unable to charge it. I wanted to throw to the garbage. I have done many upgrades many resets. While the qtek was without any software (nothing was installed on it) tha battery successfully charged. So used the qtek as ussual and tried to charge it before 20%. BUt now it fall again under 20% and it's happening the same, I can't charge it. The other strange think is, that I have tried 5 computers with USB.1 and USB.2 but is didn't help. Only one computer can charget from 0% to 100% and this one is in my work.. very strange and don't know what couse this... Normaly the battery holds power for two and half days, so don't wan't to buy new one now. If anyone has any explanation why it can be charge only with "one computer" or what can that couse, I really appreciate it.
Thank you
My atom is not getting charged.When i put it on ac adaptor it shows charging but even after 10 hoiurs the battery is empty and after removing from the power the phone shows main battery very low.
I tried charging thru laptop and same problem.
i have changed the battery also still the issue remains.
advice.

Yeah.. Atom behaves strangely sometimes.. In my case, some times when I switch on the bluetooth and try to charge it, It does not charge. But it seems to use the power coming from the charger to stay alive and operate normally (even if the battery is completely exhausted).
any suggestion how to make my atom charge
my xda atom started doing the same thing, I would plug it in and it would say that it's charging for about 5 seconds then the battery indicator would say full. Then I would unplug it and it would die out. I tried both charger & usb and the usb wouldn't work at all. So what I did is, I removed the battery let it sit for a minute. Put the battery back on and plugged the charger back in (without turning it on) and it's working. I was actually doing a search on this issue for the past couple of hours since this is the first time I've encountered this problem, but the phone seems to be charging now. I'll give everybody a update tomorrow to see if I have to keep taking out the battery everytime I want to charge it.
My problem is a bit different.
My Atom Exec charges with the USB cable synced to PC, and with one specific wall charger (specs: Input: 100-250V, Output: DC 5.5-12V, Max 1000mA, Min 150mA)
But it won't work with any other charger I try it with, even Universal charger I used to use with my HP iPaq. Is there some kind of trick to charging the Atom?
I as well have had this annoying problem happen a few times. I have a second battery and it happens with that battery as well so it has to be the Atom not 'reading the batteries' properly. As posted I have also found taking the battery our for a short time them putting it back seems to fix the problem untill it happens again
Try WM5torage. It will make your phone appear as a card reader in windows. Now pc will supply power to your device. Nice software trick.
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?

Do you mean standby or powered off? Why should it make any difference? And why does the battery getting 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...
Help
seemed to have killed the battery on my HP614c ->
battery was at lowest point ( ie last bar) but had check my email for something urgent so i hooked the HP614c up to my laptop and used internet sharing,
the power from the usb was keeping the fone alive - phone tried to switch off about 5 times but usb power was keeping it from doing so, eventually the phone auto powered off but by that time the battery was left with no charge in it what so ever !!
If i start in sd loader the charging light comes on (ie it seems to be charging the battery then), but when phone is off or if phone is switched on in normal mode, the battery does not charge at all - i think I have killed the battery totally. If i switch the phone on the charging light would come on but there is not enough power in the battery to be on for more than one second .
Is there any other mode like bootloader that will enable me to only charge the battery up ?
or does it look like I have to buy another one
have you tried leaving it charging all night with the AC adapter?
I had same problem with a blueangel...
Solution? Buy a new one battery.
ok , strange one ...
got another hp 614c handset, but both batteries charge on the new fone
(so it wasnt the battery)
basically on the old phone what happened is that when the battery was at its lowest , i connected it to internet sharing via usb port
( it kept trying to turn off but stayed on - which i though was due to usb power keeping it alive ) - that was the last time the phone was able to ''charge''... it was charging perfectly before that.
so i 2nd presumed i had damaged the usb part of the old phone
however when i connect it to usb the phone connects via active sync perfectly and as a storage device ! it is fully operational apart from charging of the battery ?
surely if the usb port was damaged it would not connect via active sync etc ?
I am confused ..
anyone shed any light on this?
FOUND THE PROBLEM
MY 64 GB USB STICK (WHICH WAS PLUGGED INTO THE SAME PORT ) IS DEAD ALSO !!
LOOKS LIKE A PROBLEM WITH THE DESKTOP COMPUTER - MAYBE A POWER SURGE
..... ARRRRRGGGGHHH ( APOLOGIES FOR ANY WASTED TIME )
STILL SEEMS STRANGE THAT THE USB TO PC PART OF IT WORKS FINE STILL BUT NO CHARGING? WHY IS THIS?
Solution (for me anyway) for battery problems
Hi!
I had this problem some time ago.
If you use 220v charger connected to the phone, the red light will probably be on.
Try to take out the battery. Connect the phone to your charger (without battery in it) and wait for the light to go green. Then put back your battery and wait.
If this doesn't work, you can use an external charger.
I had this problem 3 times. This fixed it every time for me.
