[Q] Inspire 4G flashes full battery screen when plugged in, won't turn on.

I plugged my phone in last night and when I woke up today it was off. I pulled out the charging cord and held the power button with no effect. Thinking the cord may have slipped partly out and let the phone die, I plugged it back in and was greeted by the battery charging screen, showing full charge. I pressed the power button and the phone went black. On further investigation, it seems my press of the power button didn't have to do with it turning off, as whenever I plug it in it shows the full battery screen for a couple of seconds before turning off again. If I unplug it and plug it back in it just repeats this. I've reseated the battery, I've tried holding volume down and the power button, and nothing's changed the phone's behavior. The phone is completely stock, and never opened beyond the battery and card doors.
It's pretty old and I'm pretty sure I do have an upgrade available, so I'm not too upset if I have to buy a new phone, but I'd like to confirm that it is FUBAR before I go that far, and I'd like to be able to extract my data if possible. Any suggestions would be appreciated.

If you have access to another battery, you could try that, but since you're seeing the full battery symbol I'm guessing that that's not the issue. You can always recover your sdcard data by putting it in a card reader, but the phone's apps, app data, and settings may be more difficult.

Well, turns out the problem was much less serious than I thought: my charging cord has bitten the dust. I'm not sure why I've been seeing the full battery, but when I took it to the AT&T store, the person who helped me plugged it in and it started right up. I just need to get a cable that's not my years-old piece of crap that came with the phone.

Nexus 5 won't turn on or display charging icon, no bootloop

I've had my Nexus 5 since it was released in 2013. About two years ago I started getting a dreaded bootloop and determined it was the power switch failing. I had the power switch replaced and all my problems went away.
About 6 months ago I started seeing the symptoms of a failing power switch. Random reboots which would go into a bootloop which I could stop by smacking my phone or cleaning it with video cleaner.
But then I that was getting less effective so I finally had the power switch replaced again. I have tested the switch itself, and it does close the circuit when pressed. But I am still unable to turn on my phone. When its plugged in I dont see the charging battery icon either.
But if I let it sit for a while, and hold down on the power button occassionally it will turn on and I will see the google logo, but then it shuts down. I can also hold down power+vol down and somtimes turn on in recovery mode before the phone turns off.
I can only seem to keep the phone on for 1-4 seconds before it turns off.
I'm assuming that there must be some hardware damage somewhere. Perhaps its thermal related? I havent tried freezing or heating the logicboard yet, but am now considering that. I need to boot it up long enough to transfer a couple files.
Does anyone have any thoughts on what I might try?

Black Screen of Death - Back to life, now only Always-On working, any help?

So after owning my original S8+ for 3 months, the battery died one night and upon charging the next morning, I had the black screen of death. The phone would respond to my touches, it would charge, etc but the screen would never come on.
I ended up getting a replacement and putting this one in my drawer for a year. I pulled it out a week ago and plugged it in to the charger randomly and still nothing. After 2-3 hours (enough to fully charge it), I started pulling and plugging in the charge cable, along with continuous power button cycles; and BAM, the screen came on like nothing was wrong.
I unlocked it, used it for hours, backed it up just in case; and left it running on wifi. After a couple days of it running down, it was still working fine. Once it got down to ~10% battery, the screen stopped coming on.
I charged it back up to 100% and I"m now getting the always-on screen to show up. I can see the battery %, date/time and the home button on the bottom
As soon as I hit anything though, either the screen to unlock, or the power button, the screen goes off. It is responding to my inputs and I can unlock the phone via intelligent unlock/pin code/fingerprint, but something is causing it to not light up once it kicks off the always-on screen.
I've tried resetting it, as well a pwr down+bixby+power to get in to recovery mode; but even once it restarts the screen still wont turn on until it gets back to the point the always-on screen would come on.

Wow you hyped me up at 4 am I woke up and started to unplug and plug the phone while pressing the power butto

Now by chance have you guys tried to order a battery just to see. Samsung's are noted to do really weird stuff if the batteries are failing

So not to get you excited again at 4am but... I was able to get it back to life after plugging it in and letting it charge fully then repeating the steps in my original post.
It is definitely an error relating to the waking of the phone from the always on screen. I discovered this after toggling the always on settings then using the plugging/unplugging, home button press on the screen, power button harassment on the phone, causing it to finally spazz out completely and then out of nowhere the AOD blasts on.
i know this, it seems to be perfectly ok again until the battery does start to die. once it gets down to 15-20%, it will eventually go dark again until i get lucky and it gets enough juice aid/or tired of me touching everything at once.

Duraforce E6560 boot loop

I've had this phone 3 years and it worked well. It's an unlocked ATT phone so no OTA updates other than the standard app updates. It's on Lollipop 5.1. Been working perfectly fine until yesterday, I was watching the CBS app, when the phone rebooted. Now it's stuck on a boot loop and initally went to optimizing apps which it rarely finishes but the times it does, the phone just powers off. It then got into another loop later last night where it'd get to the Kyocera logo then reboot over and over. I let it do that until the battery died 2.5 hours later. Then I kept attempting to boot until the batter was entirely drained to the point it wouldn't attempt to power up any more.(battery is not removable on this model). I've now charged it up, trying to enter recovery mode with power+volume down. That doesn't seem to register. Tried volume up+volume down+power with no effect. Now after charging, it will do the reboot loop mentioned earlier to the Kyocera logo. If I plug it into a charger, it will go to the optimizing apps portion and repeat the above. At the optimizing apps screen, if I unplug the charger, the phone powers off immediately. It appears to be holding a charge according to the charge indicator and the fact that I can try to boot over and over unplugged. Any suggestions? Phone wasn't dropped or damaged in anyway. Very weird what could have happened.

An update: Phone finally got past the "optimizing app" phase last night sitting on the charger. Out of no where the phone booted completely. However, it only works while plugged in. If I remove the charging cord, the phone shuts down after about 2 seconds. Booting without charging cord results in the same boot loop. I've considered the battery has failed however when plugging in the charger, battery shows 100% and it will decrease appropriately over time. I'm thinking there must be a hardware issues at this point. Somewhwere in the charging/power circuit. Any other suggestions?

Last update I guess. I was able to keep the phone up and booted as long as it was plugged into a wall charger. PC USB was not enough. I managed to grab my photos etc. thankfully. Factory reset the phone from the settings menu. Unplugged from charger, ran for about 2 minutes. Still said 99% charged, then went into boot loop again. Phone still shows near full charge if you let it run for awhile and decrements the charge state appropriately as time goes on. However, i guess this 3 year old phone is toast. No known reason for it to fail unfortunately. Thought I'd share the experience if anyone else has this issue.

I have the same exact problem. It started the crazy booting process in my pocket, and I did all the same things you did. Factory reset didn't correct the problem, so I'm think the battery has had a stroke. Sine your problem and my problem are very close to the same time frame, our phones are also probably about the same age, and its a quality control issue. Not bad quality control, just that these batteries were designed to last X number of months or cycles, and probably they died. Too bad, because my E6560 is the very best cell phone I have ever owned. Built like a tank and thank God for that.

mi mix 2s sudden death, need help troubleshooting

Phone was working fine, charged before sleep, left turned on in idle.
Woke up to find it stuck on MIUI boot logo, must have rebooted itself sometime during night and stuck in a reboot loop (or stuck on logo without looping)
Pressed power button and screen went black.
Wont turn back on either by plugging in charger or pressing power button.
It charges though as I measured the current, it would have been at around 70% (so drained 30% during whatever happened in the night) as took another 1000mah before charging stopped.
Never had any issue before besides an incident a few weeks ago where I swore the phone was on but it was actually off and pressing power button wouldn't turn it on. Plugged it in and after a few mintues started up as normal (with charge still present) No other issue ever experienced like random shutdowns or reboots.
