XDA II ALWAYS think it's charging

My XDA II suddenly decided to think it's always charging, EVEN when it's not in the cardle. I don't know why. The upper right corner is always yellow (not flashing). The backlight brightness can only be controlled by the 'On Power' slider. Simply, it thinks it is in the cradle. No matter how I try, be it soft or hard reset, it's the same. In this siutaution, the battery drains VERY VERY QUICKLY.
In fact, this is the 3rd time I experience this. For the previous 2 occasions, I send it back to service centre and they change a new unit for me under warranty. But it's just 5 months and it has already happened for 3 times! It's hassle and I am thinking what I can do after warranty period.
Am I being alone and anyone else has experienced the same situation? Any means I can solve it by myself? Thanks a lot.

I have same help me now

I think this is from using the cradle, for some reason it distorts the pins in the phone and causes a short between pins. I found that using a usb cable makes this less likely to happen.

hm
this is happening to me too
i had to buy a new xda 2 .... i still have the old one , if anyone knows how to fix this i would apreciate it very much. ...
it is the same story, the led is always on, it always says charning even when is not... and the battery only stays charged for 3-4 hours.

I´ve the same problem since yesterday with my T-Mobile MDA², it´s Rom Version: 1.72.01GER (6 months in use without problems), Rom Date 03/16/04, Radio 1.17.00, Protocol 1337.28, ExtRom 1.72.170
The yellow light is always on and the batterie runs very fast out of energy (1-2 hours) and it´s always says charging and think it´s connected to AC power...

Possible fix to "always charging" problem
:idea: I got the same problem yesterday but I think I fixed it. (long rant)
By coincidence I was just finishing up after an upgrade to WM5 with Ramdisk when it happened. Of cource I suspected the upgrade to be the problem.
However, I remembered that I had gotten some snow onto the PDA exiting my car some hours previously, and started to suspect that this had created a short in the system somewhere.
Looking into the charge plug hole I could see that half og the bottom of the hole was covered with some light gray stuff. I used a thoothpick to gently scrape on it and lo and behold a big (relatively) wad of pocket lint came out. It had obviously become wet from the snow and created a short.
Everything works just like normal now. Charge stays fine (especially with my new 1700mAh eBay battery, recomended)
I have not had the problem return after the "fix". Fingers crossed.
I don't think everyone has exactly the same problem but I suspect it is caused by a slight short in the plug area in most cases.
Good luck!

In relation to this, when I sync my XDA II to my PC via the cradle, the phone automatically charges (even without the power supply). Is there a way to disable this charging feature? Cause the battery life will be shortened if charging happens when the battery is not drained first.
Thanks

My 2i does this as well, from what I have read this will not damage the battery. LiOn batteries prefer to be recharged before they get fully drained, in fact they like to be topped up rather then ran flat then fully charged. This is only going by what I have read on the internet, but it was on several differnt sites so I have no reason to think the info is duff.

Tx a lot for the confortable info.

@threadstarter:
the warranty should begin again if you receive a new device!
the warranty is on the device, not on the contract you have!
if you continue that way you should have a new one every half year ;-)

[Q] Samsung Galaxy S2 - Multiple Problems

I am using Samsung Galaxy S2 unrooted (bought in India). The phone behaved properly for 2 weeks and then started giving these issues.
1. Switching Off does not really switch-off the phone. A battery symbol comes similar to the one that comes if you are charging once the phone is switched-off. However, there is also an exclamation mark (more like a thermometer) which blinks. There is no charger or USB connected.
From the above state, you cannot switch - off / on the phone unless you plug in the power adapter / USB.
2. I have noticed that while that even when USB Charger is attached, the Battery Status (Menu-> Settings-> About Phone->Status) shows "Charging(AC)".
3. A related problem to the above may be the fact that "Samsung Kies" does not start when you plug in the USB cable with the computer. The phone does not even connect to the computer via USB mode (allowing USB debugging). I have re-installed Kies / USB connectivity drivers for my PC (Win XP) a couple of times and see no change in the behaviour.
4. When charging is removed, the battery health using Z-Device Test (3rd party software) shows "Over Voltage".
I am not sure if anybody else has seen similar problems. Appreciate any help.

I have exactly the same problem. I will go with my SGS2 at the warranty this week.

Me too having same problem... Guyzzz please help us...
please do reply..
Please give some solution to the problem..

Same freaking problem here...
the battery doesnt even charge full.. it goes up to 70% and shows its completely charged..
then it drains fast too..
someone please find a hardware or software DIY fix for it...

Same problem here... I can't believe this is happening after less than a month of buying it.

I've been reading through different forums and some people got it fixed by cleaning the usb port:

samsung-galaxy-s2-international/377331-spurious-battery-temperature-warning-2.html
xdadevelopers won't let me post url's since I'm still too much of a n00b.
Here is a quote from the forum if the link does not work:
Anybody still having difficulties with this and finding this thread, go down the clean-it-yourself route. Worked for me. You will need: some isopropyl alcohol (disk cleaner), wooden toothpicks, some compressed air.
First things, remove the battery, sd and sim card.
Soak the tips of a couple of toothpicks in the isopropyl. then use them to carefully scrape the top 'tongue' in the port, the bit nearest the screen. you'll notice the toothpick gets quite dirty. Do this a few times with fresh toothpicks (or cut ff the dirty bit with sharp scissors).
Once the toothpicks aren't getting dirty any more, gently ease the tongue up, towards the screen a little, don't force it too much.
Use the compressed air to give it a good blow and leave it to dry for a while.
Its solved my problems, Battery Monitor Widget recognises that the usb is unplugged properly and no more warning triangles or poor battery performance. The phone, also gained an extra 20% of battery out of it.

I hope this helps someone else, mine is still not working.

Update:
I've been constantly cleaning the USB port very carefully. Behavior has changed in several ways. The port is still acting crazy, sometimes if I turn it off, the phone will boot up by itself, BUT...
I had it recognized by my laptop a couple of minutes ago and able to move files from and into it. Just as if everything was fine.
It came down again because of the crazy behavior of the port.
I would undoubtedly say that this is a hardware issue. I'll go buy some pressured air today to blow the port and make sure it's clean and dry.

Had the exact same issue
In Addition to battery drain, unexpected MTP app pop apps with USB connecting sound (that could go on and on for minutes). and not being able to connect USB mass storage (PC complains on device malfunction...)
After reading quite a lot forums I found out that this is a well known issue (at least for the users). I called samsung they didn't want to take any liability for the issue, and even worse they said my device is non-US device, thus I can't get support even if I wanted to pay for it.
I figured it is a HW issue, and did a little study on what replacement part are being sold on the market, short analysis showed display (well that is true for most devices, cause we tend to break them, ain't we?) and USB PCB. the latest matched my suspicion on USB HW defect. I bought the PCB for 7$ replaced it and tadam: that fixed my phone.
Samsung should check themselves, people pay 600$ for the device, if there is a manufacturing issue, they should recall and fix, just like big companies do, just like Intel did with Pentium and just like Toyota did with braking systems. nevertheless they should find an arrangement to give their customers service anytime everywhere! or better make their products not requiring service

and the problem is...
i have the exact same issue, and when i contacted samsung about it not only they did not took any liability on this matter, but they said that the warranty was voided because they found sodium residue on the usb port at the bottom of the phone, and for those of you who do no know sodium = salt = sweat, so according to samsung i voided the warranty on my gs2 because my hands sweat. not only is this complete nonsense because it is an exposed micro usb port but because this will be in contact with sweaty hands when you are holding the phone in landscape mode, so after i did some research about this problem i found that the issue is not only that the usb port is exposed but that the usb flexor and the port that it connects to are very lo quality cooper(which should be gold plated) and can very easily have corrosion problems, so the solution is to clean the usb port if detected early, but if you have been having the issue for a long time like me you need to change the usb port, flexor and the port that the flexor connects aka "the usb chip", as well as the battery since having over voltage on a battery for an extended period of time can ruin it.

[Q] Problem Nexus S - Recharges itself

I have this problem, if I turn off the phone, it appears the logo of the battery charge alone, of course, the charger is not connected.
What could be causing this?

I hear wriggling a small part of the usb tab might sort this out.

problem hardware ?

I'm too tired to do so now, but have a look over the last couple of pages in the Q&A and General forums. There have been others who had the same problem and detailed what they did to fix it. If yours is the same issue, it shouldn't be hard to fix at all. If it is not that simple, speak to Samsung for warranty purposes.

If you are tired you could not even answer
Needless to respond to accumulate posts

[Q] ASUS TF300T stuck on boot. Can anyone help?

Hello,
I have searched the threads but cannot find a situation similar to mine so am posting, but apologise in advance if this has been solved before. It's a bit of a long story. About a year ago I was foolish enough to have stood on my TF300T, cracking the screen. The tablet was still working, but it would not register touch. I put it to one side and left the battery to drain. For various reasons I have just got around to replacing the screen.
I found a screen and digitiser of the correct version for my UK TF300T (version G01) and I'd thought the replacement went without any problems, although I was slightly unsure of one digitiser connection. On pressing the power button (I had pre-charged the battery) the screen came to life just as I'd left it as if coming out of sleep rather than being off for a year. It was short lived though and soon the tablet went to black and would not turn on. I thought maybe it was the digitiser connection so went back in to re-fit it. It was only then that I noticed the power switch on the logic board itself under the plastic shell. I hadn't switched it to off before (duh) so did so then, refitted the digitiser cable much more securely,switched the power back on and tried to boot, but nothing happened at all, apart from the power LED flashing orange. After some experimenting (trying to charge the tablet again etc) I found I could only boot by charging the dock and plugging the tab in the dock, but the tablet would only get as far the ASUS screen (not the 3D one, just the flat lettering), with the 'device is unlocked' message in the top left corner and stops there. I can turn it off, but can't boot into recovery at all. And that's where I am now.
Things I have tried - a different logic board from a TF300T's scrounged from eBay which also had a cracked screen (this, weirdly, seemed to have the same problem as mine), swapping various parts out from some other TF300T's (without logic boards) from eBay and contacting the device through Sandix's ADB GUI (after downloading and extracting the SDK), which registered no device.
My best guess at what's happened is that the battery on the tab itself is totally gone (as are the three other batteries I have accumulated) after a last valiant effort and either that going or me messing with the on off switch has some how corrupted the boot process. Is that possible? What do people think? I could buy a brand new logic board, but the only ones I seem to be able to find have some different brand chips on them and appear to be different versions - versions probably not compatible with my digitiser. :S
I am quite a novice here (and maybe poking around the inside of my tab wasn't a great idea, but then neither is wearing boots in the house) so any help would be greatly appreciated! Sorry for the long post, but I wanted to give a detailed report. Let me know if you have any questions. Although unlocked, it is running the stock ROM.

I would make sure drivers are reinstalled properly, by removing the drivers, reboot the computer, reinstall the drivers and then reboot again.
See if that works.

I had something similar happen on a different tablet. That was one from Box.co.uk, but after trying to get it fixed under warranty (and missing the end date by 1 day), I opened it myself. When the charger was plugged in, it showed the charging LED, but it didn't actually charge it.
I don't suppose you've checked the terminals for the battery to the mainboard? On this other tablet, one had broken off. I re-soldered it on, charged it fully and it worked fine.

Samsung Note 7 Battery - Replacement ideas

Hello,
I'm still trying to maintain an old Note 7 N930S. Issue is that many of the posts related to battery replacement are years ago, and battery supplies have changed since then.
I also don't want to bump these old topics either.
I've tried a few "chinesium" batteries, two actually. The quality of them is dismal. The leads aren't even welded to the controller, just holding contact with tape. And I'm certainly sure it should not take only 20 minutes to go from flat to 74% on a "regular" charger either.
Even then, they cause the phone to bootloop and periodically crash in anything but Odin mode.
So the question is, what's a good source or idea to "make" a replacement battery? I do happen to have an OG controller for a Note FE battery if that's needed to "rig together" one.
