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.

This isn't the usual "won't charge to full" issue i have been reading about. The tablet is not seeing power connected. Settings>Battery does not show charging. Tasker does not see power connected. HD Widgets does not show charging. Battery bar does not show charging. Ampere (app) shows discharging.
So I did a shutdown and connected power. The tablet does a thing where it shows the battery on the screen and the red & yellow kernel stuff. Then it shows the other "flat" battery icon. Then the display blanks and does all that again and again.
I did try several reboots, hot reboots, soft reboots, long pressing power reboots.
I see an increase in battery level after it is plugged in while completely shut down. Ten minutes got me 4%.
And yes, two known good power cords on two known good outlets. Verified by connecting my phone.

Sounds like a strange issue, if the battery is dead but you are using the tablet then perhaps it is getting power since usually it will shutdown when battery level is past a certain percent (unless it is plugged in), so if that is the case there might be a few things to try
first try to hook it up to your pc see if it detects the tablet (just to make sure the usb port on the tablet is working properly) if so then that's a good sign.
if the usb port is working correctly it could be the wire connector on the actual battery inside the tablet it might have just come loose since it's just a simple press down clip that holds it inplace and a drop or other hard hit could cause it to dislodge, see the thread on how to open the tablet if you want to check, or if it is still under warranty it might be better to send it to samsung if you are uncomfortable opening the tablet yourself

Now if the usb port is not working or it's not even keeping the tablet powered on it could be anything from a failed charging mechanism, broken usb port, ...etc and probably only Samsung service center can fix it.
The battery is about 75% now… powered off until I can get more info. I am using genuine Sammy chargers and they still connect snugly. Note that it does charge when powered off.
So after an extended power off period I rebooted and charging is normal again. Still considering checking the battery connection. It has always charged slower than I would expect.
Hi everyone,
Replaced the screen on my LG G3, and now it won't turn on. Before I removed the screen, the battery was completely dead and I let it sit for a week and a half completely dead. I tested the battery with a multimeter and it shows about 2.7V across the + and -. But, the other terminals, it shows between 2.2V and 2.5V. When I plug the phone in now, there are no LED lit or anything. I tried just plugging the motherboard into a wall charger and even still, no LED lights. Oddly enough, though, I plugged the old screen back in(As well as the phone charger) and the backlight came on randomly for a second when I pressed the power button. The backlight wouldn't come back on again until i removed the power from the wall and the battery. It also helped if i unplugged and replugged the screen. It was very random. I am thinking that the motherboard grounds to the frame or something and I missed something on the install. Any thoughts? Thanks
HI All,
I recently did an unlock and ROM install and phone went great for a week or so, but now the phone suddenly shut down while on, and apparently with battery (my daughter says!) and now wont turn on at all.
If i plug it into a charger the battery filling icon turns on and the power LED lights up but then it seems to cycle off again very quickly and then stays in this cycle.
I have tried power + volume up and down combos but so far no luck. Any suggestions?
Leave the phone on wall charger for several hours. Then try holding power for a minute or so (it takes that long in certain "stuck" conditions). Also try holding power+vol up for a minute or so.
But what you describe (charge LED appears, then goes out) makes me think you may have a bad battery.
My LG G7 seems to have died over night. I left it on a Qi pad to charge and after I woke up this morning, it was completely dead. I could not turn it on with the power button ow Vol- and power button. The phone shows no reaction.
I thought that I might have misplaced it on the charger (The phone is quite picky with the right spot) and plugged in my USB charger for about 10 Minutes until i tried to start it up again. No reaction. Tried Vol+ and Power and also Vol- and Power with no luck.
Then I started to investigate and plugged a USB power meter in between phone and charger.
My first try was a cabled USB connection, the power meter shows 5,1V with about 100mA (varying between 90mA and 110mA) and I left it charging for about an hour. Still no luck with any method of turning it on.
Then just to try it out, i placed it on my Qi pad with the power meter attached, which got me 9V with about 200mA, so the Qi hardware apparently is transmitting power. Also left it there for about an hour, still no luck.
I noticed some kind of buzzing sound coming from the phone while charging, if I place my ear directly on the phone. A similar but different noise is emitted by the phone when it is not charging and I hold the power button.
Does anyone here have an idea which might return the phone to life?
As I still have warranty, I consider sending it in. I have backups of the important stuff, but I would really like to avoid sending it in with all the private stuff sill on the internal memory...
What happens when ypu plug it into your pc?
+1 same problem.
Nothing show up when connecting to pc. (no mtp,adb,9008 and etc)
Long press vol- abd power button together
