Dead

I let my phone battery die, and now I can't turn it on.
Usually I get a red light which goes when the battery is in if its charging.
Sometimes I get a red light even when the battery is in and its charging.
If I do a soft reset, sometimes I get a flashing red light on the sides but then nothing.
I managed to get it back briefly by doing all manner of hard resets and soft resets, and taking the battery out and putting it back in over and over again for about half an hour...
Then I left it charging for half an hour or so and carelessly allowed the battery to die again because I needed to take it with me somewhere - so the same thing has happened again.
I left it charging overnight but I'm not having any luck with it this morning... any help would be much appreciated.

yeah similar problem here. my phone warned me the battery was low... i ignored the warning and used it until it died completely. then it wouldn't turn on. it was late so i just plugged it into the wall charger that came with the phone. i dont think it charged cause in the morning it was still flat. if anything i think having it connected to the charger while not charging drained the last a few drops of juice out of it. had a number of confusing red lights coming up in different spots at different times.
i read on here some guy managed to charge it by getting 3 AA batteries and connecting them directly to the battery for a couple of minuets. i did this and managed to turn the phone on! hoooray!
it had 1% and died in less than a couple of minuets even though i had it on the charger. tried the 3 AA battery trick again but to no avail. i think my battery is dead.
i'm pretty certain i will need to get a new one. i hope you are able to get yours working without buying a new battery.
im really annoyed the Sony Erricson batteries work out to be close to $100 AU. i would prefer to get a legit one... but does anyone have any experience with unofficial batteries? are they any good?

Sorry you're in the same boat... Ericsson really should have made this phone so that it can run out of battery.
Interesting - tell me more about the 3 AA battery trick!

sounds like the cells in your battery isnt balancing hence its dying...think you'll need to buy another one / or at least try another one to make sure it is and not the phone...

Hmmm... I fiddled and pressed buttons and took out the charger and put it in, and then kept pressing the on button while I was doing something else...
Suddenly it made the click noise, but it's not back yet.
It seems to have crashed on the 'Sony Ericsson' start up screen with the green logo.
I don't know if it's charging or not, so I'm not sure whether to turn it off to try again (at the risk of losing the battery), or leave it to charge as it is before I turn it off and can't start it again....
At least it's progress

There are a couple vof threads with many solutions. Look for them, they are very useful.

Yeah I've found a few - Thanks... just nothing they mentioned has worked yet
I think the problem I have may be a slightly different now anyway...
Now, if I unplug it I can't turn it on, but if it's plugged into my computer cable I can get it (every time - after about 3 minutes) to go to the Sony Ericsson loading screen but no further (as if there is no hard reset file for it to load). I can do that by plugging it in, then doing a soft reset (which produces flashing lights on the side) then holding on until it clicks (usually trying that a few times). When it clicks the lights on the side flash and it looks like it charges for a second before the lights go off and its just hte loading screen. I left it for 5 minutes and it turned off completely. Nothing happens if it's plugged into the wall cable at all.
Have you any idea how I might be able be get something to load after the loading screen?... Or any thoughts as to whether you think it's likely to be charging when its on that screen?
Thanks

Hmm... It seems you have a software problem as well.
Here is what I would do: get another battery (fully charged) and try one of these hard reset methods:

Something should work...

Sweet - I managed to get the hard reset screen to ask me the question about going back to factory defaults... after that the lights on the side are coming on to show its charging....
I guess there's a chance that when the battery is charged it'll have the juice to get past the loading screen... I hope anyway.

Wow this title gave me a heart attack almost
i thought someone is dead

plz i need help
hello good day plz i neesd to flash my htc p3600 and sony ericcson cybershot i need a software i can use to flash them plz help me any body that has an idea

Xperia Wont Turn On

Ok.I seem to be having a problem that is relatively common. My Xperia battery died and wouldnt charge.
Getting the constant red light on power button when charging.
I read other peoples experiences on various forums and tried both hard and soft resets. Tried holding the volume down and power button. Tried taking the battery in and out whilst charging multiple times.
Nothing worked
Phoned vodafone and got them to send a new battery out & the exact same thing happens with that. Nothing
So on reading there isnt enough voltage through the fone to charge i bought a wall charger that the battery sits in on ebay. which has a 4.2v or 8.4v output.
It has went green indicating the battery is now charged. Yet the phone will still not turn on, enter bootmode or hard reset
I can send it back to Voda for repair but i would lose all my photos & numbers. I know its not completely dead as when i plug it into the pc via usb even though it doesnt turn the handset on widows does agknowledge that something has been plugged in
HELP PLEASE !!!!!

if your battery power lvl is too low ur xperia wont start just let it charge for 5-10 min and try again

Hello,
There is someone else here who posted about this problem about two days ago, maybe you could find his thread and see if he solved his problem.
I had some problems with my phone going dead aswell. Now I have a custom ROM and it does not happen anymore...but you will loose all your data with that method aswell (oh and your phone needs to be able to go too bootscreen in order to flash a ROM)
Good luck!

battery acting weird

hey everyone my sister has a milestone and she is having trouble with the phone battery. she says that she fully changes the phone and then at any point, the phone shows the sign that the battery is discharged and then reboots... then the battery shows the charge again, I tried moving from stock to cyanogen which took the problem away for some days but today it happened again. what can it be help!

hmm. i dunno. anyone?

the weird thing is that she just got it back from warranty... the screen was not working

Sounds like a battery problem. I once had my phone show 1% battery-level for like 7 hours (!) before it shut down. Some other time it would show 100% even though it just had been charged for minutes (starting at 5%). I fixed both issues by recalibrating the battery (search the forum, there's lots of info, most OR even have a script for that). I also leave the phone connected to the charger a couple of hours longer even after it says it's fully charged.
But if the phone actually reboots even though the battery has been fully charged, it really sounds like a hardware problem.

try a new battery

Before buying new batteries, just try calibration.
For me, the mentioned case of shutting down with a so-called empty battery was happening only with a stock 2.1.
Since then this issue never occurred again. So a faulty battery is not necessarily the first answer.

[Q] Xperia Z, Hard Brick after battery drained

Hello, just about to pull the trigger on a new xperia ZU, but i wanted to see if anyone had any tricks for me to try on my Xperia Z. I was running near the latest CM 10.2 without issues for awhile now. Last night while i was bowling the battery died( nothing new happens all the time to me ). When i returned home i hooked it up to the wall charger for about 30 minutes, came back and still no life. I have tried multiple chargers and multiple cables with no luck. Device has been plugged into power all night and all day so far. When i attempt to power on with it unplugged i get the 3 pulse red led. When i hit the power button with it plugged in all i get is a solid red LED. Nothing more, nothing less. Cant get into recovery or anything. Most of the time a hard brick involves a mis flash or something along those lines....any idea what could have happened to mine?

It might be the battery...
Its not advisable to full discharge the battery but it seems that u did it a few times..
The battery might not take any charge as the red indicator means low battery...
Tried a new battery,i know after removing the rear panel n say good bye to water resistance but is worth a try...
Or u can send it to me for free if u wanted to throw it away...
hope this helps...

Had the same thing happen
I had the same thing happen to me. From what I read trying to troubleshoot it seems like the Xperia phones in general can take 30 minutes + after a full battery drain to even register that a charger is connected. I would try just connecting it to the Sony charger for a few hours and see if that works.
There is also a tip about holding down the power button when plugging in the USB charger and continuing to hold the power button until the phone turns on. Unfortunately, can not find the original post right now. EDIT: Found it. http://talk.sonymobile.com/t5/Xperia-T-TX/Xperia-T-Wont-Charge-Turn-On/td-p/252686/page/4
In my case the red light would not even come on when the charger was connected but would come on if I held the power button down while connecting the charger. After I did this for a couple minutes the phone booted and has charged normally ever since.
So its a mixed bag. Try just charging it for a while on the Sony charger or wall charger (not USB). Or try the power button trick.
Lesson I learned is I will not let the battery completely drain again.

Ahhahha it came back alive! I had tried pretty much every trick that has been suggested and it just wouldn't charge or start to boot. Left it on the main charger again last night and still no luck this morning. Again I decided to plug it into my computer's usb port( I did this multiple times already ) and I hit the power button, a backlight came on!!! and then sure enough there was the free xperia logo! I have no idea why it finally decided to power on, but its showing 1% battery so it was truly not charging any of the times it was left on a charger, computer or mains. Thanks for the responses guys, I appreciate it!

I know this thread is pretty old. But I'm having the same trouble. Xperia Z got bricked after battery drain. It wont recognize charging, i kept it on charge two nights in a row now. It did show a red LED while charging for some time and nothing else, but now its back to being stone dead. tried holding down the power button trick, didnt budge. I thought you can only hardbrick it by doing a wrong flash/update. dont know what happened in this case. is there anything else I should try or just take it to a shop and ask to change the battery?

man, try with a new battery, here in my country cost 14 euro . Or go in a service or buy a multimeter and measure the current of ur battery. Normal they from service will give u electrosock to bring it to life. And if will dont work i think u must sell it on piece and buy another

Same problem with my Z3 Compact: one day phone became hot and started to discharge rapidly and when battery became empty, cannot charge and cannot boot, only red LED is ON. I changed the battery and phone booted again. BUT when battery was discharged completely, phone cannot boot again, only red LED is on when trying to charge.
Looks like something wrong with motherboard is happening...

Xperia ZL battery completely drained, not starting up
I know this thread is old one, but I am having issue with my Xperia ZL. Its battery drained to zero and then whenever I plug in my charger, screen starts, Xperia Logo pops up, red light also starts and suddenly everything goes off. This goes on and on infinite number of times. Phone heats up but it doesn't turn on. I had issue with my battery, a couple of months back, so I replaced it with new one. If anybody has any solution about this, please let me know.

xperia z bootloop
im stuck on bootloop and apps keep on optimising through the cycle. phone overheats too .. how do i sort this one out? ..might it be a bad battery? any help on this

[Q] battery issue. please help :)

hi everyone.
ai bought a second hand gear 1 from ebay and the seller said she obly used it twice when she got it a year ago and its been sat unused since then.
my issue is that i charge the watch up and it seems to go down normally and then when its about halfway down it just dies and wont turn on for at least 20mins then when it starts up it shows 0% battery and shuts down. then i power up again later and its back to halfway?
i have tryed resetting many times and nothing seems to work. I have also tryed putting the Null custom rom on and makes no differance. the watch is perfect apart from that. my thought is that the battery inside is stuffed from not being used for so long but not sure
thanks for ur input guys!
Matt

Does it get hot?
It may be shutting down due to excess heat, partic since you say it restarts later.
How long did you charge it for, I've read that a PC USB charge of 16 hours+ may be needed if the watch has been left sometime without charge.
Other than that it may mean that you need a new battery - sorry.

thanks very much for the advice. it was the battery. i replaced it and all seems ok now
