Help please help - Xiaomi Mi 4i

Hey I have a problem but first let me tell the story
I fell asleep with only 30% battery in my phone and when I woke up it didn't want to turn on. I tried to turn if on but didn't work. I tried to charge my phone it worked but the screen and the LED only blinked and still blinks until I post this. It's been 6 hours since I've charge my phone in that condition blinking screen and led. I've tried to unplugged from charging but my phone was totally died and still. When I tried to charge it again the blinking screen and led came. I thought it worked.
I haven't done anything to my phone

[Q] Phone Died -- Won't turn on now.

I am rooted and my Verizon GS3 will not turn on. Not sure what happened. It was not due to flashing because I hadn't flashed a rom; I noticed my phone was off so I plugged it in and went back to it in about an hour and it still would not turn on.
I tried pulling the battery. When I plug the phone in with the battery in it vibrates and then the battery screen comes on but immediately disappears (the red power LED is never on either). If I pull the battery out while the phone is still plugged in the red power LED flashes on and then off.
If I plug the phone in with no battery the red power LED comes on for about 2 seconds and the phone vibrates; the LED goes off but then nothing shows on the screen.
Is this a brick? What can I do? I am going to charge the phone overnight and see if it turns on in the morning.
Thank you in advance.

[Q] HELP- did my phone die?

today i woke up like any other day, turned on my Infuse after having a fully charged battery and after doing my morning routine i went to work. on the car i did a random screen unlock, and lock (just to see the battery level), but when i get to work my phone didnt turn on; so i removed the battery thinking it froze, and when i tried to turn it back on after re-inserting the battery nothing happened. i tried plugging into the charger but nothing happens (no vibration, no bottom lights). when plugged into wall charger, after a couple of minutes, (the right side of the back camera) starts heating up for no apparent reason. plz anyone knows whats wrong or any ideas???????

[Q] Sensation not charging, LED blinking red and green

Okay so long story short, I got my phone wet and the power button stopped working, so I put it in the oven for 10 minutes at 180F and the power button worked again. I plugged it in when I went to bed to let it charge. When I woke up, the phone was dead and the LED was blinking red and green. I did my research and learned this is a problem caused by overheating. So I've tried the method where you charge the battery with the center 2 plates covered. Did not work. I've charged with the spare battery and had no problems there.
If you guys could help me out that would be appreciated!

N5 turns off with no warning or error

Hi ! Since 4-5 days, my Nexus 5 randomly turns off with no warning.
Any idea where to start troubleshooting ? I'm clueless.
The only hint i got is, that it seems that the turning off happened at roughly same time.
I cannot turn on the phone if it happens, it boots but turns off immediately.
Could this be battery related ? I noticed today that after pluggin in the phone to use 'adb logcat', the phone booted and showed only 8% battery, but before the phone turned off, the battery was at 60-70%.
After the powers itself off, connect it to a charger to see if the led flashes red. If it does flash red, the battery is completely depleted.
It sounds like a battery problem if it happens on a stock ROM.

Water damage only orange led

Hey guys,
a few days ago I accidentally dropped an HTC One E8 in water and obviously it doesn't work anymore. Before buying a new one I wanted to ask, if some of our "HTC experts" may have suggestions on what else I could try before giving up.
The situation: I dropped it in water, didn't turn it off (dumb, I know) and it worked for around 10 minutes until it powered off. I left it in rice for a day and it didn't turn on or charge. At this point I nearly gave up.
I left it for in rice (about 48 hours) and - the orange led was flashing while charging. Even the screen turned on and it showed a charging symbol first and after a few seconds it showed a red circle and a white exclamation mark. After some time I could power it on and the touchscreen worked and I could use it, but it still was around 1%/0%. The screen flickered, but it was usable. I wanted to plug it in my computer then to rescue some data, but 5 seconds after I took it off power (to switch from the wall charger to my PC) it died.
Now I tried it to power it on for like 2 days, but with no charger connected nothing happens and when I connect the charger, the orange led is on constantly. I tried power/volume- and power/volume+, but nothing happens. Not even the charging indicator comes up, the screen is completely dead.
Are there any steps to try before giving up? By the way I don't want to disassemble it
Thanks in advance
