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?
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.
Hi,
My Z3c recently suffers this problem that the phone may turns off itself all of a sudden,
I have rooted it few months ago and it's still running 4.4.4 until now.
It first happened a day before, I charged it for a while (not for long perhaps half hour) and then unplugged it from the charger to browse some websites before sleep, but then it turned off automatically without any notice, I tried to turn it on again but it just showed me the 'Sony' and then gone black screen again, I thought it was battery running out so I plugged it back to charger, it showed that 48% battery left, then I tried to turn it on (both volume button+power on button or pressing power on button only) again but still nothing just blackness, so i just simply charged it and went to bed. I checked it the morning after, still couldn't turn on, so i unplugged it, waited for like couple hours then finally I can turn it on but the phone only got 16% battery left.
It happened twice today, blackout during charging, unplug it from charger, wait for like 30 mins ish then it'd be okay to power on.
when I try to turn it on or force power on it, it'll still vibrant as usual but just nothing to show on screen when the problem occurs
does anyone know if it's hardware or software problem? would that be solved if I just factory reset it or I must take it to sony care centre?
Hi guys, I have a huge problem.
Currently I'm on vacation in Croatia, where it's around 38-40 C every day. One day I had to log into an unsecured wi-fi. I know, i shouldn't have done that but it was urgent. Well, the same night (while charging) my phone turned off itself and I had to turn it back on on the next day. It worked the whole day until I opened the camera. Suddenly the phone went off and I wasn't able to turn it on. At first I thought the battery has drained so I plugged it into the original OP charger (dash). It gets warm while charging, but the LED is not turning on. After an hour of charging I still can't turn the phone on. Not even after a charging over night. There's also no vibration after holding the power button, neither holding the power-button for 20 (or more) seconds . I can't even get into recovery mode by holding volume-down and power.
I'm on original Resurrection Rom.
Is there anything else I could try? Could it be that some hardware is damaged (overheated)?
Since I'm on vacation there's currently no way for me to do any kind of unbricking until I find some phone-repair service.
I'm not a pro, but Im pretty sure the problem occur on the hardware side since the phone is not taking the charge and no vibration
I once had an Android phone (not 3t), the same thing occured, the phone I had had some hardware damage near the battery so I experienced the same problems you listed, ended up getting a new phone
Overheating is probably not the issue, at least not the 40C air temps you mentioned. These devices can probably something like 60C (internal temp at CPU or battery) before seeing any damage. Lot of folks live where it's just as hot as where you are, if not hotter. So I have to think the device is designed to work under such conditions.
Try holding the power button longer (a minute or more). I don't know about this device. But on my old HTC M8, there were instances where the phone powered off by itself. And the power button needed to be held over a minute, to make it boot. Although no charge LED is concerning.
Mine did the same a few days ago, was tethering and the phone just shut off. Buttons didn't work, no vibration, no charge LED, no anything. Thought it died but after plugging it into a PC it was detected as QHSUSB_BULK (hardbrick).
But it turned on normally after a minute lol.
Hallo. Mine also crashed. I was in the sunset playing game and taking pictures. Then phone suddenly got so warm and lagged, It turned off itself. No reaction. I connected into charger and then turned on hopefully. I think you must take care, because it has metal body and easy heating, and when heating it's lagging and not works good
My opinion is that it's overheat problem

You will see Qualcomm download mode message (QHSUSB_BULK) whenever the device is powered off. It needs to be powered on, at least to bootloader (or recovery or OS) for the PC to connect in any other way.
Update
After 3 days, it finally turns on and charges as expected. Don't know if it has to do anything with it, but i let it in the charger for 1 day.
but now another problem occured.
every time I press the homebutton the phone crashes and goes off. this only happenes if the fingerprintscanner is not requested.
i.e. unlocking phone with fingerprint, does not crash, but... pressimg homebutton to go back to home screen crashes.
I'm getting some strange activity on the watch:
When it runs out of battery and shuts down, I place the watch on the charging cradle while it is off, and it starts to charge as normal. It slowly charges up to 25% as usual, and then suddenly it's at 100%!!
When I boot up the watch it is at 100%, but then starts to lose charge very quickly. It's almost like the battery has become uncalibrated. I have tried running it down and then fully charging it while off and leaving it on the charging cradle for hours etc, but no help.
Anyone else with this problem, and any suggestions? (Can't send it in for warranty repair etc... cos I live in UK where they don't sell it, so had to buy it off eBay, it's a W280A which had an AT&T sim in it)
I think I may have fixed this, I'll have to wait and see how long a full charge lasts, but for the first time while powered off, it charged from 1% to 100% by 1% each time, I know because I watched it - it's been driving me crazy! So something had screwed the calibration of the battery it seems!
The fix was to keep the watch on until it powered itself off with no battery. Then try holding down the centre crown and turning it back on again - mine would get to the Google Circles on the boot animation, and then black out again - and I did this repeatedly, with the LG logo flashing up, then Google, then the circles, then it turned itself off again - so I knew there was more battery there (yes, I know these batteries keep a reserve so they are never fully discharged, and it's not good to take them all the way down, but I was only getting the thing to charge 20% or so before it showed 100). So I thought, how to keep the screen on, I can't keep turning it on again and again.
So I put it in fastboot mode, hold down the centre button and the lower button and it will bring up the fastboot screen - and I left it with the screen on, which seemed for like hours. When the screen finally went off, I tried turning it on, no LG logo screen, tried booting into fastboot, nothing - the watch was truly dead! So I held my breath and placed it on the charger. After a few moments, the white flashing ring appeared and 1% appeared in the centre, yaay!! I then watched it, repeatedly every few minutes pressing the centre crown to check the battery while it cycled through every percent until it reached 100! Now the watch is on and I am monitoring the discharge. I will let you know how it goes (before I couldn't get more than 4 or 5 hours out of it with all sensors off!)
So for all those that are getting exceptionally poor battery life out there, your watch may be lying to you - when it runs out of juice and powers off, before charging it again, turn it on again and again until nothing appears on the screen, or enter fastboot/recovery and the let the screen drain the rest of the battery. Obviously I take no responsibility if it messes up your watch.
I can confirm that this has fixed the problem. I'm getting easily one day out of the watch now, even after going out for a 2 hour half marathon mid day. This watch rocks now!

I tired your procedure but no luck
Also can confirm the fastboot drain worked - took 3+ hours (I went to bed) on high brightness but then recharged in about 2 hours and has 60% left after 8 hours use (battery saver and I turn screen off manually).
Thank you Admisi I might try this for other devices forgetting where the bottom of the battery is. Good stuff.
