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
I've search through all battery faults in the forum but haven't found a fault similar to mine.
My Diamond2 charges fine, battery lasts ok 2-3 days with normal usage. But when the low battery alert signals, I put it on charge on either mains charger or car charger and it won't charge. I can turn the phone off and it will charge fine up to 100%. I can even turn it back on once it's above 20% and it will charge fine.
It's been the same for os's 6.1, 6.5 and the energy rom i have at the moment.
I am going to flatten the battery, turn the unit off, take the battery out for 30 secs and then charge it fully while powered off. Just to see what happens.
Any Help/Advice would be gratefully received Ju
Maybe you got a bad battery. If its still under warranty, replace it.
I've been experiencing problems(like most) with battery life on the Epic, so I found a thread here from the EVO forums about "recalibrating" the battery. It involves steps of fully charging with it on, removing cable, powering down, plugging back in, etc...
Well I've actually come to realize that a blue LED should turn on when the battery is fully charged & the phone should stop charging(duh). Well i've tried for the last two days for the blue LED to come on after countless hours of charging, resetting the phone, etc. I've now had my phone on the charger for 8+ hours & my battery widget states 100% yet it continues to charge!
Has anyone else experienced anything like this?
No, but my wife's battery would drop immediately from 100% to 75% as soon as it was removed from the charger. This occurred no matter what charging regime I tried. I know that the battery may start to discharge after its peak charge has been obtained, and that it is possible to remove the charger and see only 90% on the battery, but 75%?
I returned that battery last night and now today I see that this battery never gets past 98%. I'll give it a day or so to see if the battery life degrades again, in which case I'll know it is the phone and not the battery.

Are you getting the blue light and what app are you using to tell what percent? There are other thread that say some of the battery apps are off a bit. What kind of battery life are you getting?
Success!
I used a few different apps to tell the battery charge so it wasn't the apps.
I found a fix that not only allows my battery to charge to 100% but also seems to give a better charge. Since doing this my battery shows 100% when fully charged, doesn't drop significantly when I unplug the phone, and so far has caused the battery to go down very slowly. In the three and a half hours since coming off charge the battery has gone down to 93%, while holding up to my wife using it for calls and ShopSavvy. I intend on doing the instructions below every few months.
In the Evo space there are two sets of directions on how to prep your batteries for a good charge. One involves plugging and unplugging your phone while at full charge, and the other involves briefly turning your phone on and off between charges. Because I'm impatient I've amalgamated the two with success.
Fully charge the battery with the phone on (several hours)
Once the charging light is blue, unplug the charger
Turn the phone off, then plug the charger back in, for 30-60 minutes
Unplug the charger, turn the phone on for two minutes, then turn it off.
Plug the charger back in for 30-60 minutes
Then repeat this cycle about ten times: unplug the phone for five seconds, then plug it back in until it says it is at 100% (about two minutes)
For the record, I think this has little to do with the battery and a lot to do with how the phone recognizes the battery as full.
I haven't had any of these problems. My battery charges %100 with blue light and it doesn't drop after I unplug it either. Guess I'm lucky

I don't run a battery app. When the blue light comes on it's done. I get about 11-12hours before I get the low battery warning.
Ha! It really worked. She's at 17% and its been 1 day and 11 hours. Not as good as my Evo.
I guess I'll re-try calibrating the battery again, first time I tried it my battery ended up at 95% instead of the regular 98%, really odd.

That seems a little crazy. All you should really need to do is drain it until it won't power on anymore (not even for a second) then charge to 100%.
Still, the epic's sensor just isn't very accurate at the top-end (most aren't), so you're gonna get some strange behavior near the 100%.
All the older WM phones were weird like that too in the 90% range; the sensor just can't detect it very accurately near full charge. The difference was that they showed battery in 10% increments, instead of 1% (unless you use a hacked driver).
too crazy for me.
I think I'm going to just buy some spare batteries for this phone. Immediate unplugging leads to 100% battery.

I have the same problem, I'm using battery life and juiceplotter and they give me the same %

Thanks for this. I was having trouble getting my device to recognize the top 3% of the battery, and one iteration of your plan above did the trick.
^After I noticed these steps in the Evo thread last week, following them did the trick for 1 iteration.
My phone rarely has stayed long @ 100% after coming off a full charge since then, though.
I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
So, I'm using the OEM charger that came with the phone. For the past 2 months the phone wasn't charging properly. It says it's rapidly charging, but the estimated time left was showing anything between 3 and 6 hours. In reality the phone charged to a 100% in about 3 hours. At first I thought my power outlet was the problem because it didn't behave this way every time. For that past 2 weeks it always charges slowly and sometimes even drains my battery. Last night I plugged it in and the phone had 40% battery, when I woke up the notification light was blinking red and the phone was off.
I think my charger is the culprit because the battery life is fine. Should I buy a new charger and if yes, what charger do I get because I can't find an original one anywhere ?
Thanks in advance.
