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.

Today, when i was charging my phone when it was around 20%, it didnt charge well and gave a message that the phone was draining more than it was charging. I shut my phone at let it charge, but the orange light started to blink on and off so it wasnt charging right. I tried different plugs and chargers but same deal.
Now the light doesnt come on at all, so im assuming all the battery is dead. I checked online a bit for solutions like pressing the power button and up/down button for a while, doing so under a light, leaving it charging for a while, trying to charge with my laptop usb. But nothing seems to be working.
When I try the power and up/down combo and then charge it, the light comes back for a few seconds but then vanishes. I dont know if this means anything, but in any case, I cant get my phone on so i need help. Is there anything I havent tried?
Sounds like a hardware problem, but I'm no expert. I'd take it to a repair place.

I had a similar issue months back with my m8. The micro usb port contacts had weakened and I had to put pressure on top of the area where the cable connects to the phone just to get it to charge. I was still under warranty, so I ended up taking mine back to ATT and getting it replaced for free, with them calling it a defect.
Try putting pressure on different parts of the cable when you charge it, and use a program like gsam battery monitor, to make sure it's drawing power. This will only be a temporary fix, though.
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,
I just installed a new battery into my OnePlus 3, because the old one was starting to bulge and push against the screen.
After installing the new battery and attempting to boot with the charger plugged in, the phone won't boot past the 1+ screen.
It buzzes, shows the 1+ screen for a while and then goes dark and buzzes again etc. If I pull out the charger cable it goes dark instantly.
If I hold down the volume down button and the power button for 30sec it boots and shows a warning screen saying "Battery too low. Charge for a while before powering on". However, this screen only shows for a split second before going dark again.
I added a photo of the same screen on a different phone that I found online as the screen really disappears within a few milliseconds on my phone:

Does anyone know what this means? Is the new battery faulty and should I return it? Is there something I should do to reset something? Can it be that it is simply not properly connected?
Any help is welcome! Thanks
you should leave the phone and let it charge until 100%

I let it charge all night, but obviously it is not charging...
is there anything important on the device
Just opened up my phone to put the old battery back in and that's when I saw that the connector had gotten loose. :silly:
There were some small pieces of tape on the original battery's connector that are supposed to hold it in place, so I fabricated my own out of Scotch. Hopefully that will hold the connector in place.
ok get back to me because i want to know if you have solved this
I put my phone down on the table and left. I came back and pressed the power button and it did nothing. I thought that was weird and held the power button and it didn’t turn back on. I then plugged in the device and still nothing happened. No charging LED or charge screen or anything. It is just black. I took the battery out and held the button for 30 seconds and put it back and plugged it in and nothing. I got out my USB volt meter and noticed that it is drawing power from the charger but the screen isn’t lighting up and the charge LED isn’t lighting up for whatever reason. I put in another battery I had laying around and nothing changed. Is this phone just dead or is there still hope in recovering it. I have no idea why it killed itself for no reason. Any ideas to try that can fix this?

Connect it to your pc and watch the device manager while doing so. You will likely notice a new device QHSUSB_BULK beneath other devices . If that's the case (99% chance it is) then you got catched by the ilapo ( see my signature for bootloop fix thread for workarounds which MAY work)
