[Q] Phone stopped charging after a a few odd beeps

A few hours ago my phone started emitting beeps as if some notification was turned on (I have all such off). I have not paid much attention, as the beeps eventually stopped (!!), except for when noticing, a while later, that the phone - albeit plugged in and with the battery indicator showing "charging" - the percentage was decreasing. I watched it for a while, and the batter was discharging while plugged in. Did the followings:
- replaced the battery with a new/charged one (my spare) - same behavior
- replaced the cable with the original samsung - still the same problem
- tried wall outlet charge, laptop charge (via USB), etc - same problem
The questions for those having experienced such:
- would the beeps be indicative of a problem, or just coincidental???
- the phone is definitely the culprit here - the question is if there is something that could be done for some sort of cleanup of the port, or improving the connection (seem to recall some such from a site - maybe this, maybe another forum - could not find the article by searching), or further tests I could carry out, before I take the phone into the repair shop (which I am not sure if there is such in my area)
TIA,
Stefan

can your phone charge with the phone off? Turn off the phone and then plug it in, do you see a big battery icon charging? Also is your phone rooted?

Upon turning the phone off and first plugging it in, it depicts a grey battery with a non-spinning wheel in the center. After approx. 10sec the screens starts showing a semi-filled with green battery, with a scrolling bar of dots underneath it (active this time, unlike the wheel described before).
I am sure that everyone knows what I am talking about, having seen it many times before, even if my description is not that good. The issue is that I have never paid attention to this part - mostly because I almost never had the phone plugged into power and not immediately turned on.
Observation after doing the above: after having left the phone off for almost an hour, the battery charge decreased (84% -> 80%) while the phone was plugged in.
NOTE: When the charge was 100%, by using a battery I charged with an external samsung charger, I also re-calibrated the battery using the app (phone is rooted, but always using the stock ROM). Just FYI - if that matters.
Thanks for any [ongoing] assistance.

ok if your phone was off and plugged in, and was still losing charge then I'm not sure what to do, sorry, hopefully someone else who has experienced and solved this can help you out.
my issue was similar to you where i couldn't charge my phone while it was on, i could only do it while it was off...it was a software issue, so i flashed the stock ROM, started from scratch and everything was fine from then on.
if you havent already, make a back up of all your important data (msgs, apps, etc.) download a stock rom (http://forum.xda-developers.com/showthread.php?t=2276645) and flash it, maybe that might solve the issue

The beeps may have been the phone detecting the charger on then off multiple times. Check the charge port on the phone for any breaks or debris.
Otherwise I dont know what to tell you aside from try another cable and charger. Sorry.

Damn ! I had this error too but it would charge but so SLOW! It was on a ROM/KERNEL that i've flashed , I cant remember wich one. Try charge your battery in Recovery ( this was my solution )

Galaxy S II Won't Turn On or Charge!!!

BACKGROUND:
At first, it just started turning off for no reason (probably a month and a half ago).
Then this week, it would start to randomly turn off, and start vibrating constantly when charging. After fiddling with the buttons, it would eventually find itself into download mode and then later turn itself on.
NOW:
Monday morning, after several days of draining the battery to 0% (due to me solely charging it for an hour a day), the phone went dead. Then, that night, upon trying to charge it and turn it on, it remained stuck on a black screen. After taking out the battery, it would continuously beep while still connected to the charger. As soon as I put in the battery, it would become COMPLETELY unresponsive, with and without the charger. After fiddling with it for over an hour, I put it down and slept, leaving the battery and charge in the phone.
Tuesday morning, I clicked the power button, and the phone flashed to the lock screen. It displayed it was at 0% battery, but I think it showed a charging sign. I used the phone for almost 2 minutes, checking my texts, before it again went completely black. The phone became completely unresponsive (no beeping or anything, regardless of anything I did). I connected it to a wall charger again, and left it there for the entire afternoon.
Then when I picked it up at around 6 o clock, I discovered that the continuous beeping stopped, and it would only beep after holding the power button for around 5 seconds. It could beep regardless of whether the battery was out or not.
After charging it all that night, I found I could make it flash the Samsung logo for a fraction of a second after holding down both volume buttons and the power button. I looked it up, and supposedly it brings you to recovery mode, but I believe my phone is switching off immediately after bringing up the logo.
At around 12, Tuesday night, I again decided to hold down the power button (just to reassure myself of it still somewhat functioning), and it powered on for around ten seconds (!!!) . It got all the way to the end of the pink loading bar screen, but then beeped and restarted. The second time, it lasted only around three seconds, without even getting to the loading bar screen, before powering off. It became completely unresponsive afterwards, no beeping, regardless of where it was charging and whether the battery was in or not.
Wednesday morning (today), after having left it charge all night, the phone still was completely unresponsive. I then left it to charge the entire afternoon (until now), and it was still completely unresponsive. I took it apart and played around with the power button, but it didn't seem to be stuck. I've now put it back together and leaving it connected to the wall charger once again.
What I've Tried:
Tried connecting it to Kies (computer doesn't even recognize it)
Tried putting into Recovery Mode (unresponsive)
Tried putting into Download Mode (unresponsive)
Switched chargers (unresponsive)
Held power button (beeps, now doesn't do anything)
Held both volume buttons and power button (beeps then quickly flashes samsung logo)
Cleaned off some of the micro usb lint with a tooth pick (coincided with the stopping of continuous beeping, not sure if it caused it)
What I think it could be:
Faulty power button (this is what I thought it was, but now it's not vibrating)
Faulty battery (I kept draining to 0%, but if this is the problem, it doesn't explain the phone not displaying anything when it's connected to a charger w/o battery inside)
Faulty usb charging port (I've heard it sometimes causes vibration problems. wouldnt explain the restarting).
Fried motherboard (phone has had some water damage, but I'm not sure if it's the MOBO, considering its symptoms)
HELP WOULD BE GREATLY APPRECIATED.

Not Alone
hey, this isnt really an answer, but maybe something to bump this up. Mine went last night.... won't boot, won't charge... goes into download mode but no matter how many times i switch cables, install Samsung drivers, install Keis, or anything imaginable- i cannot get it to communicate with my PC. if i could i would be able to fix this problem.
i really hope that someone will take a look at these issues and give some input. my call to Samsung was useless, i wasted hours with redundancy. I bought the phone used off Ebay in mint condition... have taken it apart and cleaned it with no avail. i fear that soon the battery will be dead and there's no way to charge it. sucks. Samsung really should recall/replace this because so many people have similar issues. whether it's the USB Flex or the battery or the motherboard they should be responsible. looks like ill be getting a nexus 4 afterall.
please let me know if you figure anything out.

It may be your battery, u need to remember why they tell u not to run the phone that way, the batteries our phones run need to maintain a certain charge in order to work correctly, if like u said u only charged it an hr or so a fah for over a week and drained completely more than once u may have rendered ur battery unable to hold a charge, in effect not allowing the phone to run its boot process, I would try a new battery, because beyond that the only other logical explanation is a hardware failure, stuck power button wouldn't render the device unresponsive only when the battery was put in like that, it would bootloop, have u ever just held ur power button in? The phone vib an shuts down a. Vib again n shut down, not become unresponsive, I would try a new battery, and if it works, respect the charge lol

I would agree, seems to be the battery. I bought 2 batteries and a 110V charger on eBay for $30. They don't have the NFC antenna in them but I've never missed it. Not only that but charging that way saves the wear and tear on the USB port.

Note 2 only shows Battery screen?

My phone died overnight yesterday, and when I got home today I found it to be dead, so I plugged it in and turned it on.
The menu where it shows an empty battery which fills up as you charge it was there, but the screen was frozen.
I tried plugging in and out the charger, tried booting with and without the battery, and each and every time, the screen with the empty battery and a frozen loading circle just comes up.
It might be my cable, so I plugged it into my HTC One X.
It worked fine, it charges but only if I bend the micro-usb side of the cable.
The reason for this is because I ran over the cable's front end with my computer chair, and somehow it only works when you angle it some way now. But, if I do angle it correctly, it will charge and if remained in that position it will charge.
I plugged the USB into my computer to see if it would read the Note 2, nothing.
Tried it with the One X, and it worked.
The very dim red LED light did come up though, when I was holding the power button.
Any ideas on what I should do?
Should I replace the USB cable? This may be a factor, but the frozen empty battery screen and the fact that the charger still works baffles me.
Some other notes:
The Note 2 is running a custom 4.4.2. ROM: W03 SLIM V9 or something.
It has also been recently hard resetted, and everything was working fine until it died last night.
What should I do!!

Swap the cable...
And not sure what you mean about the charger ???

I've managed to get the right angle of my charge and bot into recovery, and from there I booted into system.
Now it isn't stuck on the zero battery screen and is charging now

Sounds to me like the battery was drained enough that it needed some time to charge before it would even turn on. I know my old iPhone behaved like that if I let the phone die.
Glad it sorted itself out.

KF wont boot, screen flickers and shows boot logo for a split second then goes black

I was playing around with it, trying to set it up as a makeshift diy control center with an app and then suddenly the screen went black. It had been working perfectly for many years previously although the charging port was always finicky so I'd occasionally have to jiggle the cord to get it to charge (but I think that was due to the cords being too loose).
After extensive troubleshooting I concluded that it won't boot fully. The boot screen shows but in a flash it's gone, like a flicker. The device seems to refuse to allow me to turn it on when external power is connected to it, but if I sneak the charger cord in right as it is booting sometimes it will show me the battery charging animation for when the device is off (not sure what it's called but I've seen it on many devices as a standard feature) and it appears to actually be charging as it went from 84% to 87%. I also tried opening the device up and physically unplugging and then plugging the battery back in but that did the same thing as when holding the button without external power connected.
Is there any way to recover it or is it dead (it's been since 2011 that I have had this bad boy and I don't wanna lose him)?

Phone turns off suddenly for a long time

Hello,
I have a really strange problem with my A50FN/DS.
The phone turns off by itself and I can't turn it on for a minimum of two days!
Recently I had the phone plugged into the charger and it had 3% and I was watching a movie on it, all of a sudden android freezed, made a high pitched sound and a thin green line showed on the screen - the phone turned off after maybe 10 seconds. I unplugged the phone from the charger for 15 minutes and plugged it back in for the rest of the night but in the morning and for the rest of the day, the phone would not turn on. In the evening I plugged the phone into the charger and accidentally hid it under a thick cover - after an hour I came back to see if the phone would turn on, I noticed it was warm bcs of cover, I held down the power button and the phone turned on but despite charging all night it had 0% battery.... And so it worked for three days but today when I had the phone connected to my computer (I'm testing applications I'm writing) the phone turned off again and won't turn on, and on the computer I get a message that the computer can't recognize the USB device.
What could be wrong? This is terribly strange to me!
If u need any information - let me know.
What I know:
- During this time, the phone turned off twice and only when it was plugged in or connected to a computer
- I'm not sure but it turns on when I plug the phone in and hide it under, for example, a pillow to get warm. Edit: Confirmed - i plugged him in and cover him with pillow for like 40 minuts and after that time he turns on...

Failed battery, start there.
