Galaxy S II Won't Turn On or Charge!!! - T-Mobile Samsung Galaxy S II SGH-T989

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.

I might have killed my Battery (FIXED...for now)

Hey Guys,
I am running the Cell Pro 9.5 ROM and since yesterday my phone doesnt turn on.
So this is what happened, I never got a chance to recharge my phone yesterday and so I used it to the very last bit of juice. The phone kept switching itself off with the critical level battery warning and I kept turning it back on. So it got to a point where it wasn't switching on at all. So I pluged in the phone to the computer to charge and left it there for approximately an hour (the orange charging light was on), came back and tried to switch the phone back on and it didnt respond at all. Took out the battery, tried the soft reset button etc and everything else I thought of with no luck. So I plugged it back on and suddently it turned back on, did the boot up, loaded the touchflo and I saw the battery level was at "0" and then suddenly it turned of with a "tuck" sound (similar to a PC when you hold down the power button or turn the power off without shutting down). This has been repeating since then, I have left it plugged in and every 5-10 minutes or so the phone switches on by itself and shows the boot screen, go all the way till HTC animation and powers off suddenly. I have had no luck in turning the phone back on, I dont what is causing the issue - wether its the battery or the phone.
Please give me your thoughts....I am completely lost without my phone...
- issue was that the phone kept restarting as soon as the battery stored enough charge for a reboot. I pulled out the battery at one of the restart cycle as advised below and stopped it from repeating it. After that the phone let the battery charge without a restart, did not mess with it for a long while.
Never let the battery drain all the way down to 0%. Not sure if it affects the battery, but it sure will give you enough hassle that you wont repeat it.

The same thing happened to me last night... but mine works now. what I thought it was is that it kept turning on as soon as it had enough battery to do so then it would die and repeat... So every time it would turn on
I would take the battery out and let it charge some more and then when it quit turning back on I left it overnight and now its on...

Ok....I will try that and report back....
Sorry you pull the battery then the cord then put the battery back in then cord. Also it will take a lot longer if you charge it on the computer.
Never mind mine quit working again...

I managed to get it charging after pulling out the battery and putting it back again. Charged it through a computer cause i dont have my charger with me.
I turned it on and the battery said 40% and now every second or so it is dropping by 1%. I can literally watch it dropping down sitting here. The phone doesnt want to charge when it is on. I plug in the usb and the LED turns orange and then turns off. Now the battery is at 25%, This is litterally in about a minute or less. I dont know whats wrong, is it the Battery?
I had this exact same thing happen to me twice on previous HTC hardware (wizard). The first time I couldn't save it and just had to buy a new battery. However, the second time it happened I was able to resurrect it once I got it plugged into a higher-current charging source, like the wall charger it came with, or even most car chargers (that's how I saved it when I couldn't get to my wall charger). I had to let it sit on there for about an hour before it held enough charge to stay on, and another 2 hours before it was fully charged, but it worked just fine after that.
You battery may indeed be toast from what you describe. I have had the experience of totally discharging the battery and the device not coming on at all. I recommend that if you do this, you should fully charge it using the wall charger NOT the computer (if the computer works at all. it didnt in my case). I have done this a few times now and the battery turned out fine each time.

Thanks.....
My issue seamed to be fixed. I had to rely on a computer as I didnt have access to my charger and by the time I did my phone was at approximately 65% charge. I plugged it in and charged it all the way to 100%. Replugged it and left it for a little more while to make sure it got charged completely. I have been using it since today morning 9am and now it is 2pm at 73% after couple of calls, messages and emails.
Few more charging cycles with the wall charger and I am hoping it will be back to normal.

[Q] Screen dims, won't respond

Having a strange problem. I've had my EVO since launch day, been running Tommy T's Classic .06 for weeks. A couple days ago I walked by my phone on the charger and the screen looked odd, it was very dimly lit and the charge light wasn't on any more. Unplugged it, LED was blinking that I had unread mail, so it wasn't completely dead or anything.
It had been on the charger since the previous day and I'd used it several times that morning to check e-mails, text, etc with no issue. I don't think the screen was on when it happened. I tried tapping the screen, the home button, then pressing the power button.
Pressing the power button made it light up a little brighter, then pressing it again made it dimmer but not go off.
Tried holding down the power button, nothing. Finally pulled the battery and turned it back on, worked fine.
Today, same thing happened. After a battery pull it's back to normal again. I haven't installed any new programs lately, no changes, and I'm running the stock kernel from the ROM. No task killers or anything like that. It's never done this until the past couple days.
Hoping it's not dying on me, anyone have any suggestions?
Are you on your original stock battery? Sounds like the voltage regulator in the battery maybe going bad and not letting the phone get the right amout of power or letting the phone know it is getting the power
We are legion, for we are many
Possibly still using the original, I have a couple others I can try. Would that affect it while it was on the charger and fully charged?
Yeah the voltage regulator does a few things, while charging it limits the input from wall to 3.7v or less so the battery doesnt burst while off charger it communicates between phone and battery to use more or less power while in use or idle etc, when it goes bad it fails to communicate properly and may not let the battery get enough power while charging. My stock crapped out on me about a month ago and all of a sudden, woke up one day and it would die within an hr of being unplugged plug it in and it would say it was at 78% then full in 10 mins
We are legion, for we are many

[Q] What happened?

I had charged my G pad (LG version - 2 months old - stock)last night, used it briefly in the morning and put it to sleep -knock, knock, put it in its case (my knitted case) and put it away.
Tonight I take it out and it's warm at the top. It won't respond to the knock knock to turn on. I tried the power button - no response. I tried the power button numerous times - nothing. I plug it in and try the power button again - nothing. Finally the power button works and it boots up. The battery is at 90% charge.
So what the hell happened here? Any ideas???
No idea. Sounds like some app that was running hung it up. I know not everybody does this, but I always shut mine down completely while charging overnight. I think that charging while it's shut down will make the battery last longer. Plus, it stops any processes which are running, so you start out clean the next day.
Does sound like an app stayed on. I clear the RAM every time before i put it away, i don't turn it off though
I did not turn it off before I put it away -just let it sleep. In fact, I think I have turned it off maybe once since I've had it (2months). The strange thing is it was very warm yet it was off when I retrieved it from it's case .
I've read concerning my other tablet (Toshiba Thrive) that you should not charge it when it's off. I never do. I charged it when it was sleeping.
Did you charge it through your PC or in a wall electrical-plug? Did you install a new app before that or that day? Check your USB wire-cable if there is a snap on it by putting it in your tab and slowly stretching it inch by inch through your fingers if it will give a plugin or plug-out sign. And last, try your power supply plug on another device to see if its default and needs changing. To me all this is electrical related as you refer to extend temperature on the tab after power supply. There is a slight possibility of a false battery and then you take it back for service or replace.

Charged from wall electrical plug. No new apps added that day. After charging I used it for maybe 30 min in the morning and it was fine before putting it away for the day. The problem happened when I took it out of the case (my knitted case) at night and it (the top specifically) was warm yet it was off (not just sleeping) and I had trouble booting it up.
Since then it has been fine. Have charged it several times - no problem. Have put it away and taken it out several times and everything is normal.

[Q] Phone powers on for 1-5 seconds then off, won't show charging icon

So the other night I updated to cm-12.1-20150614-NIGHTLY-d2tmo, I wasn't exactly fond of lolipop, and planned on downgrading back to kitkat the next day.
However, this morning I noticed my phone was powering off, not even rebooting... and when I turned it back on, the "optimizing apps" would occur 85% of the time. I had to do some work and had it charging (low battery), and it stayed on during an hour's worth of charging... However once I stepped out, I noticed it had gone off again, so I turned it on.... and then when I wanted to turn the screen off, a short press on the power button brought up the power menu...with a slight screen flicker. Short or long, the power menu came up, and then the phone went off.
Every attempt to turn it on afterwards has resulted in the phone vibrating, and showing the S3 splash logo for about 1-2 seconds... Pressing the button combo to get into recovery mode lasts just as long, and download mode lasts about 5-6 seconds if I can hit the volume up button quickly enough. Plugging it into charge shows the battery icon for a second, and since I had disabled the LED while charging...can't tell if it's doing anything when the icon no longer shows up.
I was using an Anker extended battery since last October, so I thought that might be it. I pulled out the original battery and hoped for the best... same deal.
When I place either battery back in, it vibrates and the Samsung splash shows up for a second and then it powers off.
Plugging it in to the computer or charger without the battery in, will cause it a red LED to show followed by a vibrate, and then the LED flickers quickly 3 times before going off.
I did some Googling and it may be sudden death syndrome? Power button's gone faulty (could the battery case housing the larger Anker battery pressing against the power button be to blame?)?
Is there anything I can do?
Son of a..... I saw a few suggestions to tap (with some force) the power button, and with not much to lose, I took my original battery and gave it a couple of good taps (not with extreme force, I don't need a dented battery!). Put the battery back in, and ....... powered through fully (though still did the annoying "optimizing apps"). For the time being I won't use the Anker battery and will just use the home button to activate the screen.
I assume there are replacement power buttons/ribbons/etc?

Note 2 Will Not Power On Or Charge [SGH-T889/Rooted]

Last night I was using my phone while it was charging, but the battery was being depleted by the apps I was running faster then it was being charged. When it got down to around 3% I decided to call it a night, tapped the power button to turn off the screen, and put my phone on my nightstand so it could charge overnight like I usually do. Shortly after that I heard the phone vibrate where it shut itself off due to the battery dying which I've had happen before while trying to charge my battery when it gets to a very low charge percentage, so I didn't think anything of it and went to sleep.
This morning when I woke up I saw that my phone was stuck on the "Samsung Note II" black bootup screen and tried holding the power button to turn it off. That didn't work so I took out the battery and reinserted it. When I tried to power it back on nothing happened and even though the charger was plugged in there was no red or green charging indicator LED showing.
Since then I've tried taking out the battery and leaving it out while holding the power button for 30 seconds which I read is supposed to clear the RAM in case that is causing an issue. I've also tried connecting my Note 2 to my computer using another charging cable and it still doesn't show as charging or as being connected to my PC. I've had it plugged in for about 3 hours now in case my battery had been completely drained since it may have been stuck on the bootup screen all night long but so far after around 3 hours I'm still not getting any response from my phone.
Now I'm completely at a loss of what to do so I was hoping someone here who had a similar issue could help or if there are any other remedies for troubleshooting I could try go through. I've ordered a replacement battery from amazon which comes with an external charger but I won't be receiving it until Monday. The only other remedy I've found online is removing a capacitor but I'm going to be holding off on doing that until I've exhausted every other option available.
