Power on->Androidone logo-> battery depleted logo-> led blinks->reboots repeats again
Days ago I dropped my phone in wc, after disassembly it showed no water ingress only minor ingress from buttons but contained at this area. I cleaned and Dried, assembly and tried to turn on, no luck, no reaction, I plugged to the pc to see if shown in USB devices, nothing.
Someone asked me to check the battery, it maybe somehow depleted, when I checked it (on a magnifier) I saw I contaminated the connector with the phone's own thermal paste, I cleaned it with e-safe contact cleaner (forane), I checked battery voltage with an multimeter it shown barely over 4v, then I assembly the phone, and try to power it on, it vibrated and the androidone logo showed, then battery logo appears as depleted, then led blinks and the phone shutdown., then I plugged the charger, now the phone repeat that cycle (androidone logo -> then battery logo-> led blinks -> reset and repeat).
I keept it plugged for some minutes now and no progress shown in battery, reboot cycle continues

Hi guys,
My Xperia won't boot up, and vibrates non-stop.
I decided to take off the back cover, and take a look. After some investigation, I noticed than when I press the flex cable connector of the PWR, VLM UP and DOWN on the motherboard, it boots up.
Then is stopped doing it like this.
Now I noticed, when I press around the vibration motor connector, it stops vibrating, but when I press the bottom-right corner of the battery, it starts vibrating again. While pressing the vibration motor connector, the battery bottom right corner, and the flex cable connector of PWR and Volume, suddenly it booted again to charging mode, and now I turned it on again..
It charged from 2% to 10%, 2 times it noted that the battery is low, which means it somehow stopped charging in between, or, lost connection with the battery as it should.
Note that this is unreliable, as the phone tends to shut off at any given moment. It suddenly freezes for 2 seconds, goes off, and the red light blinks 3 times.
Note2: I've done this "pressure-therapy" a number of times, and most of the times the battery is always drained, even when I charged it to 100% the last time.
I'm not an electric engineer, but something is telling me that the battery gets drained through another source then it should. Can we call it a short-circuit? I'm not sure if the battery is messed up. Maybe some components are touching which shouldn't after I have dropped the phone.
I'm going through the same routine again and will see what the phone does when I turn it off.
Also, the date of the phone is always the same date, but that's probably because I don't have automatic time and date settings enabled.
Note I have replaced the battery (battery worked but the unit wasn't charging which tells me bad cable.) Today I had gotten a cable after a long dry spell of not having any money to spare. Plug it in. Unit light turns green, then orange, shows charging icon, then screen blinks and shows empty battery + wall plug Icon. Then turns off.
I suspect the battery is just so dead that it isn't registering as charged. Took the unit apart to plug the charger in with the battery unplugged which caused a red light and blank screen. Plugged battery back in. Same behavior as before.
Do i just keep flicking it on whenever it turns off to hope enough charge trickles in so the internal controller perks and goes 'oh wait I need to do something'?
Edit: Turns on now but it says it's at 11% and not charging. Do i flash cyanogenmod and hope thatdoes something?
So one morning I woke up and saw phone keeps rebooting(bootloop).I had breakfast then came back to pick it up,and i connected it to charger and phone was totaly dead.I tryed other cables but still same result.Only way to power it on is when I use original cable and connect it to charger/pc.Then red led turns on and display showing low battery,and led keeps blinking.Sometimes it can boot into system and works for few minutes and shuts off cuz 0%.I changed battery but everything is same,I also can go into TWRP.
**I TRIED EDL MODE/two pins or whatever and my PC is not showing Qualcom driver or anything else in relation with phone
i had same issue before, i simply just buy new cable and it working again!!
PS. Before i buy new cable i already had 3 type-c cable bot non of them working
I had the same issue an hour ago. My MI5 had ~25% charge left when I saw it shutting off, maybe I unknowingly did it. Then I decided to leave the phone in TWRP at night but in the morning it appeared to be dead. The red LED blinked only when I pressed the buttons, no turning on, fastboot or booting into TWRP was possible. When I plugged it into the charger an empty battery icon appeared with the red LED blinking continuously. After some time a new animated battery icon appeared, in the still turned off state, but this time showing the exact charge percentage (2%). It went to 3% and I turned it on with the power button.
Should be a faulty battery which needs to be replaced!

Hi guys my xsp has gone to sleep since 2 days ago. it had low battery percentage and it was in my bag. i just pick that and tried to turn it on. nothing happened. i thought it is out of charge and I plugged it in for many hours but i didn't see any signs of charging ( led or turning on. red led turns on after some minutes and turns off again) and when i removed the charger and tried to turn it on the red led blinked for 2 times for each power button pressing and no signs of turning on! i tried both yellow button in the back and volume up + power and also setting in charge for long hours. no changes! plz help
you can see video from this link https://files.fm/u/47qk6fxj
you can try jumpstarting your battery (requires a bit of disassembly), and if it still doesnt take a charge the battery protection IC (it should be part of the battery, it usually is) is bad, and you will need to replace battery.
good luck
Hello, two weeks ago my phone all of a sudden turned off and I can't turn it back on.
The only reaction I can get from it now is notification light turning on (instead of blinking) when charging. Also, when I use any vol + power combination when charging, the notification light blinks once and then goes back on. No vibration, no nothing. I tried charging it for a whole day with original charger (tried two xiaomi chargers).
I managed to tear down the phone, and plug off a battery from a motherboard. When I plug in a charger, with battery plugged off, the phone reacts exactly the same (no vibration, no screen activity, only notification led).
So my question is: could it be that the battery alone is faulty, or could it be something else? I will highly appreciate any help!
