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.

So I took my charger with me to class today because my phone was almost dead. As it was charging I began to fiddle with it ex: go on reddit . Suddenly The phone began to lag and the screen shut off. I unplugged it and began to hold down the power button.... Had it held down for about a minute and still no results. The charging light is stuck green even when off the charger and the navigation buttons are stuck on. When holding down the power button the navigation buttons would also flash as it normally does but im not getting any feedback from the device. Anyone have any solutions? I need my phone to be working asap. If there isnt any hope i may as well upgrade.
Little update: I let the battery die out and plugged it into the charger. After half hour it still wouldn't turn on. Several hours after that I found it on and running. Very strange....
TL;DR, phone dropped on the floor, flat on screen, no damage except for a ratling noise in the bottomleft corner of the phone where the vibration is, which i didnt notice until after i dropped the phone. Charged a few times, but refused alot of the times, now it doesn't charge anymore.
Right now, every time I connect the phone to a charger, it starts showing the red LED, vibrates non-stop, until after 15 minutes it stops vibrating, giving fast pulses of vibration to slower pulses, and for the last 30 minutes, while connected to my laptop, it gives off a medium-soft vibration every 5 seconds, slowly degrading to every 20 to 30 seconds after half an hour.Interestingly aswell, it vibrates very strong for the first 30 seconds, than vibrates normally for the next 15 minutes before it stops vibrating. It's very consistent in this behaviour
Full story:
I bought the phone April 2013, and it was working fine until somewhere November 2013.
The percentage of the battery wasn't consistent at all. It was jumping every few seconds between e.g. 70, 73, 67. 60, 70, 71... sometimes it fell down to 23%, next thing happens, the system gives me a pop-up "Shutting down". It shuts down normally, I boot it up normally, and that's pretty much how it went. I made backups, continued with the use. Sony Customer Care tells me that I should update it/reset to factory settings.
I connected the phone for an update, and as the phone is updating, it shuts off because of the problem stated above (even with cable...).
Phone bricked, sent it April 2014 for service because I had a different phone and I was too lazy to send it back.
3 weeks ago I got my phone back, fully working (Yaay, right?). 2 weeks ago, I was sitting, doing my natural business and put the phone on a shirt I had at the window. The slippery phone pretty much slides from anything that's soft and has the slighest angle, so my phone starts sliding super slowly, and 10 seconds later it hits the floor screen down.
It fell so perfectly flat on the screen, on the perfectly flat tile, that the screen is still perfectly clean and there is no sign of damage. But, the phone was off (it was on before it fell). Shocked, I boot the phone, and it boots, with a sense of relieve I continue using it. However, I did hear a rattling noise from the bottom-left corner where the vibration is located (vibrator... hihi).
Here's where the new problems start...
Day 1, I shut down my phone on 15% so I save battery for later, for pics and such. Suddenly when I try to boot it, it tells me the battery is too low (a few red led flashes). 1 hour later, it turns on with only using the power button.
Day 2, I use the phone normally, phone drops to 2% and just waited until it would shut down by itself. It didn't, stayed like this until 1%, to where I have shut it down and plugged into the USB cable.
Day 3, The phone didn't show any LED, and when I would reconnect it to the AC charger, it would show the red led for about a minute and go off again. Phone stopped charging... Later I tried the car charger, still nothing. A few hours later I tried the car charger again and suddenly it started charging again to the full 100%.
Day 5, I had the phone in my pocket, and had to drive for about 60km. The phone was at 30%, and I found it to be turned off, showing me the battery is low through the red led. 60km was about 30 minutes, so I sensed something was wrong here. It didn't charge again, nor through PC or AC charger, not even the car charger.
Day 6, I tried the car charger, and again, it started charging, got it again to the 100%. I'm just browsing in the afternoon at 51%, and my screen turns black. I press the power button to light the screen, but it blinks 3 times red. I put the phone in the charger, nothing... Later that evening I put it again in the charger and left it for an hour, and the red LED finally showed! Well, the red LED was lit for at least 12 hours and the phone didn't respond to anything.
Day 7, It did vibrate 3 times when it tried the Power Button + Volume down, but blinked red again and no response.
Day 8, I started pressing the phone gently, and it started to vibrate on pressure. Pressing = vibration, release pressure = vibration stopped. What?? It could keep this up for about 5 minutes before it stopped.
For the last few days i try charging it occasionally, but the only progress that I got, is that the phone started vibrating non-stop when it was connected to a power-source, and the red LED was lit. First it would stop vibrating when I pressed the sides of the phone in a certain way, and just lay there silently with the red led. Now it just vibrates non-stop and there's no helping it.
Right now, every time I connect the phone to a charger, it starts showing the red LED, vibrates non-stop, until after 15 minutes it stops vibrating, giving fast pulses of vibration to slower pulses, and for the last 30 minutes, while connected to my laptop, it gives off a medium-soft vibration every 5 seconds, slowly degrading to every 20 to 30 seconds after half an hour.Interestingly aswell, it vibrates very strong for the first 30 seconds, than vibrates normally for the next 15 minutes before it stops vibrating. It's very consistent in this behaviour.
So, I found this thread:
http://forum.xda-developers.com/xperia-z/help/hardware-fix-xperia-z-charging-booting-t2760911
I contacted Sony Support, they said there are no VOID indicators in the phone, as they will be able to tell if there has been a person in the phone. There's an unauthorized service nearby who can order OEM Xperia Z parts, so I doubt it they will notice. When I asked if I would still have warranty after the unauthorized service, but they would be unable to tell because he/she used OEM parts, they simply said "You will lose your warranty", because they probably couldn't contradict it.
Judging from the symptoms, do you assume it's a dead battery, or could it be someting completely else? It dropped, something rattles and it gave me a hard time charging it, but still it worked. Note that I used the phone intensively for 6 hours before the screen went black at 51% (fairly the same as using your phone to 0% and suddenly it just turns off).
I don't feel like losing my phone for 30 days again, nor getting my data wiped (ALWAYS BACKUP, I was too stuborn not to, even though I had plenty of chances...), and i'd rather just pay a few bucks to get my battery replaced (about 50 dollars). The time and data is worth it, there is a shop servicing Sony Xperia's after warranty, so at least someone who knows how to fix these phones.
The back-cover is not water resistant anymore as the glue detached because of the excessive heat from the processor. So I might just open up the phone and see whats going on anyway?
Alright, so I was clumsy enough to drain my Xperia SEVERAL TIMES.
Honestly I blame the software or calibration, but also myself, since it didn't shut down when it should.
The following would happen, that my phone wouldn't charge. No red LED, nothing. Then when it showed, after countless tries and different power sources, it finally did. It worked like 3 times. Then it started shutting down at 30%, then once when I was using it at 50%. All of a sudden. Since then, it died. It didn't charge, even after I left it for 2 days on the charger. I tried every week, but nothing would happen. Eventually the phone would start vibrating when plugged into the charger, and just die after exactly 30 minutes, every time, giving pulses of vibration.
I opened up the phone, disconnected the battery, and pressed the connector of the vibration motor.
When the vibration is non-stop, even whent he phone is off, it's because of a faulty vibration motor itself, or its connector!! I only had to press it and it stopped.
I left the battery disconnected for 1 to 2 weeks, I don't remember. When I felt the CPU cover, it was kind of electrocuting me. I put a paper between the black strip that leads between the battery and the motherboard, to which somehow the electrocution stopped. I left it charging for 2 days, with the RED led full on all the time. I gave it little hope, but I still pressed the power button mutliple times through out the charging time. This morning, te RED led was Dark Red, very weak. I pressed PWR + VLM DOWN and it gave a little pulse.
It's alive again! I let it charge to 100%, made immediately a backup, and I'll see if it will keep working. I will have to send the phone back to Sony anyway, as I think that the vibration motor will start acting up again as soon as I pick up the phone from the table (it's that sensistive yes). Also, I cannot leave the paper there, and I just want a full functioning phone. Only need to get the silicone glue strip from a distributor that I know so I can properly close it off.
I didn't send it because I needed my data, basically.
I would say, if your phone doesn't react to anything and you're out of warranty, it's worth it to keep trying to charge it, or take the shortcut and buy a new battery, open the phone and connect the new battery. It's really that simple. Otherwise, it might be your motherboard that's dead.
I hope this could help some future troubles of XDA's. Maybe make a new sticky, as this question comes along quite often?
Can someone tell me what this flex cable is connecting?
My phone would sometimes spontanously freeze and switch off, showing the 3 red leds and just stops responding. It won't even take a charge. Usually the battery is at 60% when the phone dies, and sometimes it shows a constant RED led.
The back cover is loose (but has enough adhesive to actually stick reasonably, takes little force to open it up), so I pressed that connector with medium force. The next thing that happened, is that the phone responded to the charger, booted to the "charging state", where it shows the battery state and so on (which it shows it's approx on 60%.
Or could it be that I press something else, which causes my phone to work properly again?

Cable with connector in green box is for side keys, gyro and microphone. :good:

Thanks/Hvala!
But do you know what could be faulty on this specific point, which causes my phone to not charge? Can I find somewhere a complete guide to the disassembly and identification of all parts? It would make it alot easier for me . My phone is running again, going strong at 65% and still discharging for the last 3 hours. I'm logging the microVolts, temperature and other stats from the battery to see if it's the battery causing the malfunction, which I doubt.
Anyway, there should be something. By the way, prior to the issues, my phone dropped flat on the screen on tiles, about 1 meter high. So most likely, there is something loose/messed up. But I don't know what causes the entire system to flash the LED 3 times, saying that the battery is drained, yet after pressing on this point, immediately start up while on the charger.

Please PM me. (you speak croatian?)
I swapped the battery on my F8131 and now when my phone boots up, I get to my main screen and the screen turns off. The phone still works, clearly, as my alarm was going off this morning, but the screen won't turn back on unless I re-seat the battery. Then the process repeats itself. Touch works, as I can swipe before the screen turns off.
I've re-seated all the connections, dried it out, put the old battery back in, pulled each component one by one to see if it was shorting, power drained the phone. Nothing fixed the issue. I can't get to the recovery menu as the volume buttons don't work properly.
Any thoughts?
Did it get wet?
If so take out the battery asap!!!
