My defy is barely 2 months old, i am running CM7.1 since it was released and its quite smooth with no problems till now.
But recently i went to a remote place (i made another post somewhere) and switched SIM cards, i switched back SIM again now. Since then, my defy randomly dies sometimes while holding it and most times while in my pocket. My battery percent looks fine (i wiped it just in case).
This happened to me several times, i suspected the battery was loose, so at the beginning i reinserted my battery 2-3 times and it would start again. But now even after reinserting the battery it refuses to turn on, i usually need to connect it to a charger (or USB) and after the LED light turns on, i can switch it back on, disconnect it and use it again.. until it dies again randomly.
I tried inserting a piece of paper as padding to prevent the battery from moving, but didnt help much. When i shake it a bit, it dies too, so it might be a loose battery or some hardware problem, but the reason im baffled is why i cant turn it on again without connecting it to a charger, and also why it dies randomly when i leave it alone and didnt even touch it. Also, i never dropped it even once or mishandle it at all to make the battery be loose, when i insert tha battery, it still snaps/click into place just like when it was new.
ANy help suggestions will be appreciated. Sorry for the long post, just wanted to provide a detailed account.
I found an almost similar problem but no answer here http://forum.xda-developers.com/showthread.php?t=1109429
Firstly, check if your setVsel settings is all ok and not too low down specially the voltages settings. If you're not using SetVsel, then check your 2nd-ini in system - overclock settings, see if it enable and check those individual settings which might be too low that caused the phone under power/voltage and triggered self shut down.
Another option to narrow down your issue is trying another battery. Buy or borrow from a friend. If the case of random shut down still occur, then it might be hardware issue in your Defy mainboard. BUT.. I would flash it to another rom to make 100% sure before sending it back to the shop.
Thanks a lot for the reply, im not sure if its an overclock or vsel issue because it even dies sometime while booting up if i move it around, so im guessing battery or mainboard issue?? Ill have to check with another battery first then... hoping its not a mainboard issue coz the nearest service centre is miles away from where i live
Couple of weeks ago my gnex fail to start a boot after my battery used up to %0. I used a wall charger but it did not help, I mean there were no charging screen, no boot animation, no vibration that indicate start boot. I assumed battery was so low, it would not boot enough to charge, so I used an cheap battery charger to charge the battery, then everything worked as expected. this happened one more time, that made me think there was a issue about the rom or some software, but I did not act on it. Then a few days ago my phone rejected to try to boot even with full battery.
I search the forums, and find out connecting to wall charger then inserting battery will trigger a boot, and it really did. Then I flashed official google image to see if it fixes the issue but no luck, then I tried odin flash with repartitioning, still no luck.
Currently I am on full stock on my gnex. If I shut it down, no matter which button/combination I try, it won't trigger a boot. If I connect to a wall charger while battery is in, screen does not turn on and charging does not start. If I remove the battery, connect to wall charger, then insert the battery, charging screen came up, then if I press power button for ~5 second it boots to android like everything is okey, and after boot starts, I can disconnect the charger, no issues about battery.
I have no clue what might be causing this. Power button works, battery works, rom/software works, are there anyone with some ideas what might be causing this?
it is very interesting. may it be battery problem?

I tried a friends battery on my device, and my battery on his, mine did not boot, but his one did, I don't think there are anything wrong with battery.
It boots now but unstable
Hi again. Not booting issue seems to be fixed (without doing anything) but now it reboots when I try to download anything. I used stability test to check if cpu or gpu has any issue, the test did not found any issue.
I am suspecting my internal storage causing this issues, but I could not find any tool to check/fix it. Are there anyone that knows a way to do so?
I wanted to report back my last status. The phone is working normally know. I tried out flashing different kernels, and at some point, random reboots stopped. To verify, I downloaded several GB of files, tested with antutu and 3dmark, everything looks normal.
Long story short, I have no idea how it got fixed, but it did. I suggest anybody with my situation to keep trying, I bought a g2 thinking it would not be usable, I regret that decision now.
Hi guys, I'm experiencing some power issue with my ZL. I have recently updated via Seus to .283 firmware....once I reboot, it gets to the Sony screen and then it shuts down. If the phone is plugged in it boots fine and remains on. The battery charge shows 80%. Afterwards I unlocked the bootloader and flashed the KK advanced kernel to see the battery percentage in recovery and it also shows 80%. Is there anyway to check if its the battery without replacing it?

There is a battery testing app for Sony devices (you can find it here), but, obviously, it requires your phone to be able to stay on battery power for the time of the testing...
What happens with your phone if you unplug the charger once fully booted? Does it immediately shut down, or is only happening during startup?
The phone shuts down immediately after I remove the usb cord. Offline charging looks as though it's working. I'll see what the app says, thank you.
* btw the phone stays on when in recovery which is odd
* the battery app requires you to remove power which I cannot do
* help me!..using a Z Ultra at the moment...things huge!

Well, yeah, that's what I meant saying the phone has to be able to stay on battery...
I think (just an uneducated guess ) that the recovery doesn't have a mechanism to analyze battery health/status, but the Android OS does (and so does the bootloader). That's why it stays on in recovery, but when booted (or in the process of booting) into the OS, the system somehow thinks that the battery level is too low, and shuts down as a safety measure. I have seen multiple times that the battery levels shown in recovery and in Android are drastically different, which kinda confirms my thoughts...
All in all, it looks to me like your battery is acting up. Just to save you an effort and expense of getting a new battery, at least until you know for sure the battery is the problem, I can suggest something to you... I am expecting a replacement for my battery in a day or two. My old (current) battery still works, it's just old and doesn't last very long, that's why I am replacing it. I could send the old one to you (Vancouver to Winnipeg is not a big deal), so you can try it out to pinpoint the problem. If it works, then you know it's the battery, and you can either buy a new one, or keep my old one for the time being. If you are OK with the idea, just send me a PM with the address to send it to.
I think I'm just going to buy a battery of ebay. I really appreciate your offer to send me your old battery, but its probably best I go new since I don't want this issue arising again. Thanks again for all your help.

No problem! I was just thinking you could use my battery to confirm the problem before buying the new one, not to keep it for the long term, of course (that would be silly). But I am pretty sure it's the battery, anyway... Good luck!
I was wondering if the battery ever fixed the problem, I am having the same issue
really mad, I'm going on a business trip and this started happening. this week I updated the firmware to 293.
I didn't know you could replace the ZL battery.
After 2 years of use, my phone suddenly just died when I was playing a game. It won't boot without the charger ever since. I'm so sad because I expected this phone to last longer
Hi all,
I have been running my Z1 Compact on 4.4.4 for the longest time, mainly due to sound issues after updating to Lollipop.
Recently, the battery has been dropping randomly from 60 odd percent to 3 or 4 and then shutting down all within a few seconds. The last time it did this, I tried charging it when I got home but the charging light would not stay on, thus it was not charging. All typical signs of battery failure due to age.
Having already replaced the battery successfully on my Z1, I bought a replacement original Sony battery and replaced it. The problem persisted. On first boot, the phone got to the blue waves then black screen, and power off. Charging screen just showed the battery at about 40%.
I risked it and flashed the latest software with Flashtool, having done a complete wipe. The result of this proved no better, but I did get a different message on the charging screen, a message saying the phone had shut down due to overheating. Picture is attached.
The phone is in no way overheating and I've even booted it while sat on a shelf in the fridge to help dissipate any heat generated but with no luck.
So, the old battery maybe did overheat and caused the phone to shut down, I'll accept that as a probability. It may have even damaged something, but I don't think that's likely.
After changing the battery, I would have expected the problem to resolve itself, but it seems like some kind of hardware 'flag' has been raised that is now not allowing the phone to boot in case it overheats again.
Does anyone know of any way to resolve this, reset the 'flag' per se, other than going to Sony? The phone is definitely out of warranty due to its age, never mind me taking the back off lol
It is a shame because it has been a great phone over the years, and I would like to fix it if possible, even if to give it to one of the grandkids. I have my Z3 still (which I won't part with for anything) and I have an XZ too and both are great phones. I would just like to save the XZ1c if I can.
The phone is not, and has never been modified in any way, no rooting, no bootloader unlocking. Only stock roms have ever been flashed, and then only once or twice, to put it back on 4.4.4.
I have tried reflashing just the kernel, or just the system too, to no avail.
In desperation I even left it in the fridge for a few hours in case the temperature sensor was on the fritz, but that did nothing at all.
I just feel like there's nothing actually wrong with the phone, apart from this trigger that won't reset.
Any help greatly appreciated of course.
Thanks,
Mick
Maybe theres lot of consideration:
1. Rom Bugs
2. The Kernel not supported well
3. Battery Issues (But you already change it right)
There are two temperature sensors afaikin our phone. One in the SOC and another one in the battery (hence three pins).
The battery is probably the one giving the high temp report. Try yet another battery.
A bad battery normally heats up very fast inside and the battery temp sensor stops the battery from charging and/or working to protect the phone and the battery.
I changed my battery before when it had symptoms like yours 100-90-0 drop and after replacing with a battery from eBay it was OK. I gave it a full charge then complete discharge and then complete charge to full cycle the battery once and let the phone Guage its full capacity. one year later now my battery is acting funny again (not charging past 30%) and getting so hot when charging it triggers overheat control service in Android.
Any luck?
Apologies for the necro. But did you ever fix this issue, having the same problem

No, I never did figure it out. I've been loathe to spend more money on another battery when I've got other much newer phones. I really have no idea why it would not reset once the battery was replaced, maybe it's the replacement battery.
Have you tried changing the battery?
I've tried flashing different stock roms, Kit Kat, Lollipop, and it doesn't help.
Short of going to Sony, I'm not sure what else to do.
Z5 Premium not turning on
hello everyone,
PLEASE HELP ME!
My z5 premium was working fine.. battery was charged too, and suddenly it turned off, and it didn't turn on back again. I've tried all the different ways and solutions that should turn it back on:
hard reset didn't work
2 minutes hard reset didn't work
hard reset button didn't work
plugged it in using it's OEM charger and usb cable didn't work either and LED didn't lit up
plugged it in to the computer nothing happened, wasn't detected with no sign of life
I had to take off it's battery cover (using professional tools) unplugged the battery, connected the phone to the charger while the battery is unplugged, and nothing happened reconnected the battery back, and plugged the phone again to it's wall charger, and no sign of life.
i left it there all night long since the afternoon. and when i came back in the next morning to check if the phone is charging and the LED is lit up, but again NO SIGN OF LIFE!
(BTW, the phone is in mint condition and it was never been disassembled or repaired)
Please if anyone have an idea what this could be?
if anyone has encountered the same problem and went through the same of what I've been, and was able to repair it or find a solution PLEASE LET ME KNOW!
Now, I'm thinking of 2 things: either the battery is completely dead(damaged) or it's the mainboard which I don't hope to be.
PLEASE LET ME KNOW YOUR THOUGHTS ABOUT THIS!
Now, forget about any sort of software repair, as I explained above, the phone didn't succeed in that.
So, any help or suggestion would be so much appreciated.
Thank you all for taking time in reading and participating in this topic.
Have a good day.

Not happy reading this thread. Why so many issues with Sony Android... Anyway;;
- I recently had the same issue - or an issue in the same ball park. Phone Just died and refused to charge, but would show a red LED and try to boot when plugged in.
- Sent it to Sony, Hoping it is only a dead battery
The OP sounds like a they have a USB port issue or a board issue, also OP phone will no longer waterproof after removal of cover.
Unclear as to whether you have tried the following;
- Turn on whist holding camera button instead of Volume up/down. it is worth a try
- Try to grab an official sony charging cable- basically impossible to buy nowadays, maybe a PS4 controller cable? try it
My stock unrooted Z5p died like this in April. Have the same issue as the OP and tried all the same solutions. My Z5p had only been used indoors for months with WiFi before sudden death. Replacing the charging port did nothing. Using the OEM cable and charger with a new battery gets a 2 sec red light when connected to power and starts booting up until the swirls (gets past Sony Xperia and powered by android screens). Then the screen goes dark and shows the big battery for a couple of seconds.
I didn't realize there was a sudden death problem with Sony phones until I started trying to fix this. What's even crazier is that I had (have) the Xperia Z, Z Ultra, and the Z2. The Z2 was used in the rain constantly and even survived an ejection from a handlebar mount at 15mph onto asphalt. (All these phones were rooted and using custom ROMs/kernels.) Seems like Sony has a serious QC issue they're not taking about.
