When the battery of my Universal is more then 50% full it will recharge.
If it falls below 50% it doesn't recharge anymore when I plug in the adapter or PC-USB.
Luckily my father has an Universal too. So I can occasionally recharge my battery in his Universal when I forget to recharge mine. But ofcourse that's not the sollution.
Anybody knows this problem and how to fix it?
Sound like a software problem....
Thanx in advance.
Never heard of that problem, did you try to charge your father's battery in your Universal?
I'll try that this weekend. Than I'll be more certain if it is the battery or the Universel it self.
But in the meanwhile I hope that someone recognizes this and had an answer.

Hi everybody.
To get the most out of my battery I always wait until my device shuts down due to lacking battery. The I chargt it until it the end and the battery displays 6+ houres.
When I recharge the battery before its empty I only get 4+ houres when its full.
I also read that the battery's lifetime is increased by only charging it that way.
My problem is the cradle that charges it everytime I sync.
Is there a way or tool to switch charging on/off for the cradel?
Thanks alot
Alex
The way I understand it, modern batteries do better when charged regularly in small increments. They do very badly with multiple deep discharges, which can actually damage them.
So I would actually disagree with you that what you are doing is a good idea.
If you still decide to do this, the simplest way is probably a manual activesync via bluetooth, using a dongle, as it actually charges via USB too.
Surur
Right the bluetooth thing would be a good idea.
And you might also be right that you should not charge it in such an extreme way...
I read this an a PC Magazin.
I don't know if its wrong or right. the only thing I know is that the battery lasts longer when I charge it thta way.
Thanks

The battery in the xda2 is designed for constant charging, I dont see how you would get more battery life because if you acheive your desired aim the xda2 will be discharging during sync and will give less battery time than if you let it top up the charge.
I read that Ion battaries have only a limited number of complete chargings bevor the are broken...

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
Is there someone els who hast got this problem?
The battery level reaches 28% and my XDA Neo switchs itself off. The only way to power it on again, is to connect it with the charger, the USB-cable does not work.
Is it an ROM-Bug or does my battery has got a defect?
I hope someone can help me
Ciao
A sudden drain?
Try checking what % you see just after plugging to mains.
If you see 3-5%, this is the battery draining very fast. So, time to replace it?.
If not, hmmm well, i have to think about that...
After plug in the charger, the battery level is still at 28%.
The battery is new, i bought my device just 4 weeks ago.
Try with another battery
I check in my registry but don't see anything special to modify. Looks like there no key to define a shut-down threshold.
Unfortunately, i've got nothing miracleous to tell:
Try reproducing the same shutoff with another battery. If happens again, then device to repair. If not reproduced, that's the battery.
LiIon batteries have internal controllers to check their charge level. When he device sees 28%, this may be reported wrong bythe controll and real charge may be 1%. That's just a guess but that kind of error should not happen with a new battery.
I'm going to send my battery to the service...
Yes, there are no problems, if I use another battery.
BTW: I heared about, that some other people had nearly the same problem with there battery... maybe it's a failure in a series of batteries?
I've left my JAMin for a month and now I can not turn it on.Any ideas? Why the battery is not charging? I think I'm going insane Do I have to buy a new battery? PLEASE HELP ME
If you are trying to charge using usb from computer or other source it probably won't revive a really discharged phone.
Instead you need to use the wall charger, leave it plugged in overnight then check the phone out.

Batt Charging is controlled by the OS/ROM, so if the batt is completely dead the phone in all probability not charge it.
You may not need to buy a new Batt if you can find a seperate batt. charging unit....
Else, a new batterry.
10x guys.I hope I will charge it today Hope dies last
happen to me before, if you can't charge it up, you either have buy a standalone battery charger from ebay or just postive & negative to boose a charge into the battery (for pros only)
Hi Folks,
I have quite a big problem and hope that somebody here can maybe help me
Some weeks ago, my HTC Prophet fell into Water.
Now, when I try to charge my Prophet, the Battery DISCHARGES quite fast...
I tried the normal Charging device, as well as charging it with my USB cable and with the charging device in my car...its always the same
I also tried several different batteries (even the ones that didnt fall into water), but no success...
Do you know any solution for my problem besides charging my battery with an external device and not inside my phone?
Maybe a hint, what inside of my phone may be broken? And if it could be repaired?
Thanks alot,
Greetings,
Armitage
