Hi
I noticed a strange thing about LG Optimus One (500h):
Even if the phone is plugged into a wall charger or PC when running power hungry
app (wi-fi hotspot) the battery initially at 100% keeps DISCHARGING! even being supplied external power all the time!
What happens in 3-4 hours it completly dies and until charged you can't turn phone on.
My guess is that the phone still uses battery power even when the external power source is present, and power from usb only goes to charging circuits, and not to the rest of the unit.
Seems that it always needs battery.
Just tested, powered up once without battery (have to hold power button for 10 secs) and then shuts down anyway upon getting home screen.
It indicate some kinda bug or indecision by engineers, firmware boots OK, but once Android has booted it's says "No, need battery to work", so it might be
software fix.
So this morning i unplugged my phone, fully charged, and used a flashlight app. Then all of the sudden my phone just went black and i have not been able to get it to do anything for over an hour and a half now. No matter what i do it will not turn on. Ive tried to power button/rockers combo to get it to turn on, nothing, Ive tried the little button in the sd card compartment, nothing.... Anyone else have this issue? I cannot find anything on the Z3 for this, only stuff for the older models... Thanks.
Hold volume up and power button until the phone vibrates. Then connect a USB cable to your computer while holding volume down on the phone. If the phone is recognised by the pc you should be able to flash your phone using flash tool and hopefully that will get you back up and running. That's the only solution I can think of. Maybe some other members might be able to help if this don't work.

Nothing... I cant get the phone to do anything at all. I really do not understand.
I can't help then mate other than suggesting taking it back to where you got it from or sending it to Sony. Hopefully somebody else can help you out to save you the hassle

Did you hold the buttons in for ages; literally 20 or 30 seconds?

Hello, my girlfriend have the same problem in his Xperia Z3. When she works his phone lying on the desk. She want call to me and the power/lock button don't work. She call to me from other mobile phone and she describe problem. After 10 seconds search in google I find a way to restart phone. She pressed little yellow switch under nano Sim/micro SD plug. Phone power down and never give up. Power button is dead, combinations : vol+ and power , vol- and power, vol+ and vol- and power also didn't work. When I plug the USB cable the charging will start normally. In screen I have a big battery icon with animation.
Maybe someone have similar problem with Z3 and know a solution??
Well if its the button, tap to wake could solve the problem till you decide to get it repaired.
It could also be a battery issue. Try charging for a few hours on a charger and then try turning on after connecting to a PC with phone drivers by holding the power button for like 10secs. That is the method used for HTC phones with similar issues.
The HTC One X had battery issues for some where it would not turn on until it was connected to thr charger for a few hours. I had, had the same issue you mentioned and tried the method mentioned above but never turned on. Repair shop tested the battery and eventually had to replace a bad mothetboard.
That is not normal and even if you could get it back from that sort of failure, you don't want this device unless it is fixed or replaced.

Still nothing. Power/unlock button is dead. Today I go to sell point (T-mobile Poland ) and leave for warranty repair. I used Xperia Z3 for 2 weeks
If you are within 14 days TMO should give you a brand new device.
I'm having the same problem too. I tried to use the flashlight app for the first time and it just completely bricked my Z3.

Hello,
Xperia Z3 back from repair few days ago. Message from service: hardware repair, updated soft, phone is 100% functionality and compatible with specification from producer.
Ive just received my z3 as replacement for g flex and its from Plus poland lol.
Sent from my Xperia Z3 using XDA Free mobile app
Just happened to me today- Xperia Z3 Compact
So last night, i left my phone to charge after reaching 5%. When I woke up, my phone won't start and it won't charge either. The LED indicator was not lighting when it is plugged.
I tried every trick:
1. Pressed down the power button in different lengths.
2. No. 1 but with the volume down key
3. Pressed down the yellow button on the sim card tray
4. Tested 5 different charger heads and different wires
5. Tried connecting to 2 different laptops to see if my phone will be recognized
I work close by a Sony Center so I was planning on passing by after work. I was already having a really bad day and my phone is not under warranty. Throughout the morning, I'd randomly check the power button if it will finally work. FORTUNATELY, during lunch, the LED indicator finally lit up! The batt was drained so I had to charge it and wait a few minutes before turning it on. Finally it's on. I don't know what the eff happened or if it is really resolved.
I'd still want to know what the hell is wrong with Xperia Z phones??
Mines 'died' twice, both times the only way I could get it to turn back on was to connect to magnetic charger dock/cable
this is really works on me.. !!! try this one.....

just do the no .3 ... and it works to me... thank u for posting this .. it helps me a lot.......
It's called the 'sudden death' bug and a small number of sony xperia phones die from it., including the Z3. It is more common in the Z3 Compact (I suffered from it and had to get it replaced). Just google sony Z3 sudden death.
Did the OP use a quick charger on his Z3? The reason I ask is that the repairer I sent my Z3C to originally said the motherboard was gone and needed to be replaced, possibly cased by current. I used to use a quick charger on my Z3C and wonder if it caused it as the phone worked perfectly for 6 weeks before dying.
There are several so called fixes and workarounds that work for some people, not all. Only a motherboard replacement fixes it properly.
Fix for Z3 not powering up / no charge LED
My Z3 would not power up and no charge LED when cable plugged in. Finally found this solution on Sonymobile support website which fixed my phone!
To force the device to restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") until the device has emitted three vibrations, and then release the OFF button. The device turns off automatically.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
If a forced restart procedure as described above doesn't succeed in turning on your device, you should try another kind of forced restart - the 2-minute restart procedure.
To force a 2-minute restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") for 120 seconds (ignoring any vibrations), and then release the OFF button.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
I had to hold the 'off' button for about 60 seconds before the phone vibrated and sprung into life - phew!
I bought mine with the broken screen so I don't know for sure what happened. Bid won for $37
The led light came on when plugged in, but no vibrations. The computer recognized it and installed as the D6633. Properties show the battery had charged to 29%, 60%, 99%.
But clicking into it just shows a blank page. No folders, drive volumes, or anything.
However if it is not hooked up to a charger or computer then as well as no vibration there is no lights either. Does get a little warm though.
Bought the new display and powerflex. Still wont turn on, no vibrations, and only shows led when plugged in.
Tried the volume up, down, power, all three, reset button in sim tray.
PC Companion can't work with it. It almost worked once but said if there was a google account and I did not have the info I would be facing the whole account lock fiasco....No thank you. Can't even get it to recognize it for that option properly anymore anyway.
Could easily connect it into fastboot mode, but getting it into flash mode took much much much more effort. But eventually I did and flashed an image with flash tool. Went fine. Flashed everything......NO CHANGE......
I'm guessing at this point maybe the board was more damaged than seems....Though it's weird how the computer recognizes it and can flash everything.
Or there is a damaged power IC, transistor, capacitor, or something.
I really hope Sony took care of this in the Z5 and it is no longer an issue in future devices. It was said in a few comments above that only a few people are affected....Yet there are endless searches and pages with a dramatic number of users facing it.
Hey everyone, I am facing a very unusual problem. My phone few days back turned off on its own in spite of having enough charge in the battery. When I pressed the power button to start the phone, it won't start!!! I plug in the charger but nothing happens. No charging symbol nothing.
I take the phone to service center. Representative over there tells me it's the charging IC problem and it needs to be replaced. I said OK and he replaced it. Phone turns on and it's charging and everything is fine.
I go home and I am using it and suddenly it reboots on its own. This happens multiple times at irregular intervals of time. After a few hours phone shuts down again and won't start. Again back to ground zero.
Anyone who can help? What do you think, is it hardware or software issue?.
Running Android 5.1 and not rooted.
Is the battery physically damaged?
One of my S4's suffered the grey battery bug today, so the symptoms were:
Device would not switch on (Samsung logo appeared, but switched off within a second)
Device would not charge (grey battery with a circle, but no actual charging seemingly took place)
Device would switch on with a different battery.
I could not get the device to charge or switch on, but through a strange set of steps, I was able to make it charge and it eventually started working. These may work for you, or they may not, so just bear that in mind.
1. Plug phone into charger, leave on the grey battery for a few seconds.
2. Pull the cable and hold the power button.
3. When the Samsung logo appears, immediately plug the cable back in.
When I did this, the phone seemed to get stuck at the Samsung logo. So it did not boot, and it did not go off either. I left it for about 2 or 3 minutes.
4. Pull the cable and the battery after 2 or 3 minutes. Put the battery back in.
5. Plug the USB connector.
After doing this, my grey battery (which seemed completely unable to charge before) went to a green (almost entirely depleted) and slowly started to charge. I left it for half an hour before switching on the phone. Voila, it's now working and up to 58%.
I can't say what causes this issue, I've heard that it can be caused by defective USB charge boards, but I'm not convinced because unless the socket itself is damaged the board itself really shouldn't fail. It's possibly being caused by low powered chargers (like my USB cable which I used). I observed a similar issue on the N4 (red light of death), after using a similar low power charger.
Anyway, this might be useful, or might be useless, but if it saves you a few quid then it's worth it
you save my life thanks
I recently dropped my phone on the ground and the glass is now broken. But it worked normally for about 14 days. Then suddenly one day at work it shut down on its own. After that I wasn't able to start it. No reaction for any of the buttons, nor their combinations. Even when I plugged the charger in, no sign of life. I thought it's over.
Then the next day, I plugged the charger in and the screen with 0% battery appeared. So I left it charging, but when I came back to it (20 minutes) it was dead again. Not even the diode indicating it is charging. Again no response for the buttons, nothing. So I tried to disassemble it, disconnected everything. Put it together and viola! The screen indicating 0% battery was there again. I left it like that for a while, and when it was charged a little, I tried to start it. It started and normally worked. At least it seemed to, but after a while (1 - 3 minutes) while I was using it, it went to the dead phone again.
So I discovered, that when I disconnect the battery for a while and then connect it again, I am able to boot the phone. I was even able to do factory reset. I thought I got it and that it was some software fault. However after like 5 minutes (it downloaded all apps, logged to my google account, looked all ok) the screen shut down again and again the phone played dead.
Now I have the phone booted, and charging (almost 100% now). But I guess when I start using it again, it will again go to the dead mode (since it did it everytime after I used it a little, no specific action done, totally random).
I guess it has to be related to the broken glass. Maybe some water or humidity got through it and the phone is trying to save itself from damage by going to the dead mode. It's weird because sometimes (like now) the phone is OK when not used, normally chraging and not shutting down (now it's ON for about 40 minutes), but if it shuts down, it takes about 3 or 4 battery disconnect and connect again, before it boots to the main screen. Sometimes it just dies before the screen, sometimes it dies when I try to plug the charger in, really no idea what causes it.
How should I diagnose it? USB debugging and check the log when using it and when it dies? Or has anyone experienced this too? Or could the battery be damaged? Or can I somewhere set the phone to prevent from selfkilling actions? Today I will try my main board in my friends G Flex 2, to see if it's the board, or something else.

Adding the error log from console
OK so it was probably mother board fault, so I had to buy a new phone It is like 3 months, and I just yesterday accidentally poured some water on it, so i destroyed another one. It is still in warranty but I guess with water damage there is no warranty. Anyone knows where to find all the water damage indicators? Or is it even possible to make it look like there was no water damage?
