[Q] Desire doesn't charge and won't boot up

Hey guys,
Last week I was at the bar taking a picture from some nice girls, unfortanly my Desire slipped from my hand an fell pretty hard on the floor. It was off an didn't boot. After a night without the battery, the next day it booted and worked for an week, no problems at all. Yesterday my phone shutted off again and now I can't boot it at all again, left it the whole night at the charger, but that didn't seem to help, ive searched the forums but nothing helped. The strange thing is, that it worked for an week and now it doesn't anymore. Does someone knows a proper solution for this, my phone is rooted and RCMixHD 2.0 is running on it. help?

Ok, I found out that I still have warranty at my provider! But, do they start whining if they found out my phone has an custom rom?

Hi.
I think that more than for sure there will be problems if they are able to find that you have ROOT-ed your phone since this breaks the warranty. Anyway try leaving it without battery in for a day and see if this can make the phone boot up. You could also try another battery, if you have a friend with the same phone or you are able to go to a store and ask to try out a battery to see if that is the problem.
If that is your problem you can, I think go to warranty and say that your problem is the battery.
It would be recommended that you run a RUU if you are to go to warranty. If they find out you messed with the phone I think your warranty will be gone forever.
If the battery is not the problem, then I think you can't do anything, since your phone doesn't even boot up, but go to warranty and pray that they wont examine too deep and see the root.
Still I have one curiosity: the led is still showing that you are charging the phone (the orange, green led)?

Thanx for your reply, I tried another battery but that didn't help . The led doesnt show up if I put an charger in it (tried with different chargers/cables the phone isnt doing anything. The last time it stopped working I didn't use the phone for about 8 hours, and after that I booted and worked fine for an week. So hopefully he wil work again this evening so I can make him stock again for warranty.

Hi.
As it sounds, it could be a motherboard problem, or the usb connection on the phone, or anything else, but since it isn't working with any battery then it is surely from the motherboard.
Hope it starts one more time so you can bring it to stock.
Even if this fails, there's nothing else to try but getting it to warranty and cross fingers.
Good luck.

[Q] My Note 2 has died. Help?

My Note 2 has just died It was getting surprisingly laggy at odd moments in the past week, but I didn't think anything was wrong. I was updating a lot of applications one after another tonight (music was playing but it was jumpy, i think because apps were updating so i stopped music) and people were messaging me on the facebook app so I could see the notification light flash green. I was busy on my laptop, so I ignored the phone about 10 mins.
The green light kept flashing, but the screen wouldn't turn on when i pressed home or power key. so i took the battery out from the back and reinserted it. It wouldn't switch on at all, no SGS Note 2, no Samsung logo. nothing at all except a little red light flashing where the infrared light is everytime i tried to turn it on.
I tried connecting it to my computer. nothing happened. recovery mode bootup also failed. I tried charging the phone, even though the battery wasn't empty, still wouldn't switch on during charger plugged in or pulled out. Took out SD/Sim, no effect. A new battery didn't help. The phone doesn't charge either, the charger makes a funny electrical whining noise and the infrared red light flashes every so often.
It's basically dead. What can I do? The phone is also rooted, I can't remember how (think it's original chainfire root? i got my phone last oct). Will Samsung be able to switch on my phone and discover it's rooted? Also I read somewhere that legally speaking if rooting didn't cause the failure, you're still covered by EU law?
I am in the UK, bought Note 2 off a 3rd party reseller (Buymobilephones) who provided a handset, and T-Mobile for the contract.
Thanks

How long ago did you buy the phone?
If you were rooted, were you on stock rom?
If yes, than which build were you on, do you remember?
I have heard of phones dying from sds, were you on an older rom. If that is the case, and if you have hard bricked your phone, AND if you are under warranty you need not fear...the guys at samsung wouldn't be able to open your phone either to check whether its rooted or not, you are covered. Your phone would require a motherboard rwplacement 8n that case. I hope you had backups.

I bought it at end of last october, 1st gen/batch of Note 2s to hit the UK (IMEI starts with 354.....
I was rooted. The first auto-root Chainfire method via Odin.
Stock samsung rom. Very earliest versions of software.
I basically bought the phone last year when it first came out, rooted it as soon as possible and then did nothing else except enjoying my phone and install new apps. Whatever people were rooting/flashing/roms/kernels etc at the end of last october when the note 2 first came out in the uk is what I would have been on. Never updated since.
I might sound a bit stupid, but does a motherboard change means you lose everything in internal storage? ie photos, texts, contacts etc. I have no backups of anything. my fault I know. And Samsung wont' detect root after motherboard has been changed?
When you say "hardbricked", do you just mean it wont' physically and electrically turn on? Because i didn't interrupt rooting/flashing etc.
I googled SDS for the Note 2. Seems there is an issue I can't think how else my phone would just die.

I think we know the cause now, its sds. Only roms and kernels which have been developed after January 2013 are free of this problem. As you had rooted very early you would not have recieved stock updates from samsung. And as you had not flashed anything new, the rom/kernel you used had the sds problem. Had you recieved stock updates or had you flashed any latest rom your device would most probably be working.
Now the good news is, as I said, samsung has no way of learning whether your phone was rooted or not. A soft brick is when your phone is in a bootloop. A hardbrick means it wont't turn on, won't do anything at all. Your phone is hardbricked in a way. So a samsung engineer would be as powerless to turn your phone on in this condition as you are. And thus, you would be under warranty.
The bad news is, yes, all the data on your internal storage is gone. The phone you would be provided would be a new factory reset model altogether. That is of course, if the problem is sds, as it seems right now. Even if the problem is different, something smaller, a factory reset is what you will get in all probability, so no chance of saving the data.
I am really sorry for your data, and I know it doesn't help when I play Captain Hindsight, but you should have made a titanium and nandroid backup at the very least. Do that for your next phone regularly. It is the most useful aspect of rooting your phone if you ask me.
Of course, I could be wrong here. The problem could be something smaller. I suggest you throw this problem @dr.ketan on this thread

[Q] [Help] Phone shutting down when unplugged

Hi,
I'm experiencing some problems with my Xperia ZQ (C6503), which I bought less than a month ago, and would like to know if someone could help me, I'm getting desperate
The problem:
When turning on the phone, it displays the SONY logo (or DooMLoRD's, if I install TWRP recovery) for about 3 or 4 seconds, then shuts down (I can't even get to the boot animation, where there's the XPERIA logo and the waves).
The only way to get it to boot is turning it on while having the USB cable connected to a charger or PC. It will work just fine until I unplug it.
At this point, if I leave it alone and only access the home screen or SMS app, it will remain on until the battery is fully discharged. However, if I open any other app like WiFi networks, camera, contacts etc., it WILL shut down and I'll have to plug it again to be able to boot up...
What I did with the phone before this happened:
- Rooted using DooMLoRD Easy Rooting Toolkit and used it for a few days
- Unlocked boot loader with Flashtool
- Flashed DooMLoRD's CWM-Based Recovery 6.0.3.2
- Installed AOKP MR1 Milestone 2 (Android 4.2.2) and used it for a couple weeks
What I did trying to solve the problem:
- Wiped data/cache/dalvik cache
- Flashed various stock brazilian ROMs through Flashtool (10.3.A.1.434, 10.3.1.A.2.67 and 10.3.A.0.423) countless times
- Flashed AOKP again
- Restored to 10.3.1.A.2.67 using Sony Update Service (had to relock the bootloader with Flashtool)
- Tried updating using Sony PC Companion but it said I'm already in the latest version
- Tried to use Sony Emma but I can't get login credentials (I'm not receiving the confirmation e-mail)
I followed some instructions for similar problems in the Q&A forum but most of them end saying the owner had to send the phone to warranty, but they never say what's the outcome...
Do you think I'll have to do the same? If so, is there anything more to before sending it, other than relocking the bootloader and flashing stock firmware?
Thanks and sorry for the lengthy thread

Unfortunately, what you read is right and you need to send it to servise center for repair unless you can change the battery itself yourselves...
Otherwise their is nothing you can do but to send it to Sony...
I have similar problem and because some don't say the outcome yet is because haven't receive the phone yet...like me, I have been waiting nearly 2 month for it to repair it by sony...
Don't know wether Sony accept my warranty or not because I have unlocked the bootloader and root...but before send I already relock it and unroot it..so hope Sony didn't find that out...
Of you have warranty, what you can do is just do the same...and hoping for the best...
Press thanks if this help....

My unit is still in the service and awaiting battery. The same problem, which as far as I know is only present to the ZL model, and the root cause is the malfunctioning battery. I did not do anything with my C6502, its completely stock, but the dealer wants me to present a receipt for them to acknowledge the warrantry of my unit. I politely told them that the unit is several months old and it has not been opened and in pure stock condition. What then will be my protection when the unit was a gift from my daughter I argued.
In short I did not prevail and yes it is bummer considering that the phone is about 3 months old in pure stock condition. I am beginning to doubt the brand and how they stand behind their product. First time to use Sony, Am currently using my old reliable Samsung Galaxy S2 while waiting for the ZL battery. Yes I will pay for everything. parts and labor. [email protected]#$ accept my apologies for releasing. . .

its happening to the Z as well.
I went through this September, it took 5 weeks and they sent me an Xperia Z as replacement which was great because the ZL development stalled.

some info
The problem is with the BMS (battery management system) inside the battery pack (--> http://en.wikipedia.org/wiki/Battery_management_system).
If an unsafe state is detected, the BMS shuts down the battery to prevent it from severe damage (fire, etc.).
Some people manage to "repair" the BMS by going through several charge and discharge cycles but this doesn't always work.
A few years back we've played around with some cheap lithium polymer battery packs without BMS.
On heavy discharg load around 50% of the cells caught fire.. (Well, we were building an electronic car for the formula student, but the concept is the same )
If you send your phone in to Sony, in most cases they don't change the battery, they just reset the BMS.
This problem can occur with all modern lithium batteries, depending on the BMS thats used inside.
I'll post here if I find a way to reset the BMS for the ZL battery, but I don't think it's that easy..
And still, you would have to open your device and connect the battery to a small microcontroller (if someone has programming skills, it might work with the Arduino board..?!?)
Depending on where you live, it can take very long (2 months plus) until you get your phone back.
You might think about replacing the battery yourself.. You can find them on ebay and several battery suppliers online for around 35$.
Here you can find the service documents: http://forum.xda-developers.com/showthread.php?t=2516874

my ZL too had this strange auto shutdown thingy, mine was fully stock, no root no unlocking.
i sent it to sony for repair. they sent me a new ZL within a week saying it had some problems with the battery.
i live in India.

Thanks for the information, I knew it was something with the battery. Some people said their phone came back to life after reconnecting the battery.
EDIT: I don't know anything about this battery management system, but Z/ZL seems to have a pretty dumb one.
Since I just got the phone and wouldn't open it, i tried discharging the battery but things got worse, the phone got stuck on a boot loop with the red LED blinking 3 times and was not charging again.
Thankfully it charged back when I tried with the original charger and cable (they were at work).
I just dropped the phone at an authorized repair center, they'll sent it to Sony and I will (or should) receive it back in up to 20 days.
Will let you guys know when I get any news.

OK, got my phone back (a new one, actually) this saturday, after 22 days.
They confirmed the problem was something with the battery.
Thanks for all the help!

That's good to hear that you got it back. I just sent my ZL in for this same issue.

Sony Repair Service is awful.
Onsi~ did it take 22 business days or 22 calendar days? Mine phone has been at Sony's repair center for 31 calendar days 20 business days and the repair center just seems to be sitting on their hands. Sony's tech support doesn't seem like they can push it along either.

Hello dr2005k,
It took 22 days (16 business days).
The deadline given by the attendant was initially in days, but when I called them near the end of the deadline they claimed it was in business days .
It all depends on your agreement with the repair center. If it has already expired and they are sitting in their hands, like you said, you can complain to them (if you didn't already) and maybe say you would sue them if they don't give your phone back. (Even if you don't intend to, they will get scared and try to solve your problem a little faster ).
Also try contacting Sony directly, that's what I was about to do.
I had a last resort option, in my contry (Brazil) there's a law that states if the product spends more than 30 days in the repair center, the manufacturer has to give you another one (brand new, not refurbished) or your money back.

My Xperia ZL started shutting down when unplugged
My ZL is also shutting down when unplugged. Will changing the battery help?

Most likely but you'll most likely have to send it to a Sony repair facility for warranty work. I hope you have better luck than I do getting your phone repaired and sent back.

Exactly the same problem here buddy...
Here's a little email I've sent Sony Tech Support and their Press people:
"I've purchased my Xperia ZL in the United States (online at the end of March 2013 at ATGSM.com) and started using it mid April, 2013. I currently live in Sao Paulo, Brazil.
After using this phone normally for about 9 months, there was this one day back on the first week of January 2014, where I was taking lots of photos at the world famous "Serra da Capivara National Park" and could just feel the phone heating up like never before. Next thing I know, the screen went blank and phone would not respond when I pressed the power button.
I had to pres the reset button in the back of the phone in order to make it work again. But once I tried to load the camera app, the phone would automatically shut itself off. I thought it could be related to a faulty or corrupted External SD Card, so I went ahead and removed that as well before I attempted to turn my phone back on. After the system loaded up again I tried to oped the camera app and the phone turned itself off again. Any app that would require a significant amount of processing power would cause the phone to freeze and shut off.
So I decided to charge the phone all the way up until 100% (while powered off). When it reached 100% I turned it back on and used it normally (while it was still plugged to the wall charger), so I thought... Great, the phone is "OK again"! Then I went ahead and unplugged the phone off the charger, expecting it to function normally... In just a matter of minutes, with just a little bit of usage (checking emails or browsing the web) the phone simply shuts itself off on its own, yet again. I tried to turn the phone back on again and just as before, I was greeted by the Sony logo and - without any warnings or alerts - the screen simply goes blank again and that's it. This is all it does on the battery.
I've searched online for a solution for this problem and I got nowhere. My phone is all stock, bootloader locked, not rooted. I've formatted and updated it with the latest Firmware (10.4.B.0.569) a couple of times using Sony's Update Service application for Windows to no avail. Nothing seems to fix this battery/shut down on its own problem. There's tons of other Sony users complaining about similar issues with their Xperias. Just look up "xperia zl shuts off" on Google and you'll see what I mean.
My phone is one big dud...
So there you have it - one big useless US$650 piece of hardware. That only functions normally when it's plugged into a wall charger or your average computer USB port.
Not much of a "mobile" phone if you ask me.
I'm extremely unhappy with Sony's hardware and their inflexible technical support.
I've purchased this device in the United States and they can only grant me tech support under my 1 year manufacturer's warranty if I ship it over to their facility in Texas for repairs. That's no big deal for me. The one big problem is: They want me to have a US shipping address so they can ship if over to that address after they finish repairing/replacing/refurbishing my phone. And I've got a big problem with that.
I do not live in the United States. How am I supposed to pick my phone up over there?
After doing some digging through my phone's IMEI, Sony's tech support representatives brought to my attention that my device is a "Grey Market" phone (meant to be used in Singapore?) and that they don't even know how long it will take for them to service my phone. According to their supervisor, it could take anywhere from 1 month up to 4 months, maybe even more for them to repair and send it back to me.
See what I'm going through here?!?!?!
What good is it for a company as big as Sony to print and place a cute little warranty pamphlet inside the box of your brand new phone, containing the numbers of several different technical support worldwide if the 1 year warranty is not going to be covered in all of those different countries??????????????
I took the initiative to call Sony's specialized Xperia Mobile support telephone number from that pamphlet that came with my phone (not a free call, by the way) here in Brazil and shared with them my frustration regarding my Xperia ZL. They were sympathetic with me, and readily provided me with 3 different authorized service centers near my home, with their respective addresses and telephone numbers.
I managed to reach a couple of those authorized repair centers here in Brazil (over the phone) only to find out that they DO NOT have any of these Xperia ZL / ZQ batteries in stock. They also mentioned that several other customers called them and shared their bad experiences with their Xperia ZQ's battery life (defective batteries) and were greeted the same way: "I'm sorry, we can't help you. We do not carry that replacement battery in stock. We have already placed the order for those with Sony, but there's no estimate of when or even if these will ever arrive in our store anytime soon... I'm sorry about that..."
Yeah, I'm sorry about that too Sony.
I'm really sorry I bought a Sony smartphone.
I wish I could go back in time and buy a Samsung Galaxy S4 Google Play Edition instead.
But it's too late... I've already spent 650 bucks on your crappy smartphone, Sony.
Looking back, I can tell you that I've had problems with lots of other computer components that I've purchased in the States, from several different manufacturers. And I've RMA'd lots of these defective memory modules (RAM), defective SD Cards, etc. I've shipped it from Brazil straight to them in the States and in less than 1 month after they received my RMA, they went ahead and shipped a replacement back to me (in Brazil) FREE OF CHARGE! Most importantly, with NO HASSLE! That's right, NONE of these companies refused to ship it back to me at my Brazilian address like Sony is doing to me at this time.
This is the worst customer support from such a big and Global company that I've ever dealt with in my entire life.
Shame on you Sony!
After this horrible experience, here's a few things that I CAN and WILL DO for sure:
- I will NEVER buy another Sony device (camera, smartphone or laptop) ever again.
- I will never recommend a Sony product to any of my friends and family.
- I will never buy another phone with a built in, internal battery.
Sony has been continuously releasing and flooding the market with new phones that doesn't add a whole lot of improvements over their previous gen devices (ZR - Z - ZL - Z1 - Z1 Ultra - Z1S and so on). All they do is depreciate the value of what they have already released just a few months for just a little more, sometimes even less money than what you paid for your current "last gen" Sony phone just 2 or 3 months ago.
The Xperia ZL was released with last gen Snapdragon S4 Pro and in just a couple of months after I purchased my ZL they released a new, better spec'd smartphone, the Xperia Z1. And now, Sony has just announced the Xperia Z1S...
I understand that in today's mobile market / segment it's "the norm" to have this ever evolving and improving trend of new technology on mobile devices, but this seems to be getting kind of out of hand. You buy something today for US$650, sometimes even more depending on where on earth you live, only to see it become seemingly obsolete in just a matter of 3 months.
Sighs...
I'm through with Sony."
Sorry for making it lengthy as well!

My ZL is also shutting down when unplugged. Will changing the battery help?

I suggest you to first try restoring your device with Sony Update Service (it's in Sony website, just Google for it). If the problem persists, you now have a charger-dependant smartphone.....
Not sure if replacing the battery will help... I've read that someone fixed the problem just by detaching the battery cable, waiting a few minutes and then plugging it back, but I can't verify that.
Keep in mind that opening you device will void the warranty.
You can send it to repair center if it's still in warranty (or if you're willing to pay), but remove any customisation before that (eg. lock bootloader, restore TA partition etc.).

Those are my feelings, exactly.
I really fail to understand why Sony did nothing to correct this problem since it's clearly visible that ALL Xperia Z(insert letter/number here) models have this issue. Some start to show the symptoms on the first week and others after 1 year.
I love my Xperia ZQ/ZL, it's an awesome phone, but I have this feeling that this problem will occur again (bad luck if it's after the warranty...) and I should just have bought another model/brand (not the S4 though )...
That being said, whenever someone asks me for advice to buy a new phone, I tell them to get away from the new Xperias. They are great phones, but you may be granted in the battery issue lotto

Yes and it's being sent back again.

Well I got my phone back from Sony Tuesday Night. And it's going back today... Sigh. They sent me back my old phone after offering me a new one which kinda annoyed me. Then when I tried to actually call someone with it they couldn't hear me and I found out that the main microphone is now broken. Hopefully it doesn't take another 6 weeks to get a fixed or replacement. I'm a very patient person but this is starting to wear that down really quick. I never had warranty work be this useless.

Agr! this is the exact problem with my phone. Just started this week, i start the camera app and the phone crashes! I had to keep it on charge for the most part to get it to work, so.. its a wired phone now.
Can someone document a quick way to get it fixed or replacement, where did you start? sony chat, email or visiting a repair store?

Hi,
I'm experiencing some problems with my Xperia ZQ (C6503), which I bought less than a month ago, and would like to know if someone could help me, I'm getting desperate
The problem:
When turning on the phone, it displays the SONY logo (or DooMLoRD's, if I install TWRP recovery) for about 3 or 4 seconds, then shuts down (I can't even get to the boot animation, where there's the XPERIA logo and the waves).
The only way to get it to boot is turning it on while having the USB cable connected to a charger or PC. It will work just fine until I unplug it.
At this point, if I leave it alone and only access the home screen or SMS app, it will remain on until the battery is fully discharged. However, if I open any other app like WiFi networks, camera, contacts etc., it WILL shut down and I'll have to plug it again to be able to boot up...
What I did with the phone before this happened:
- Rooted using DooMLoRD Easy Rooting Toolkit and used it for a few days
- Unlocked boot loader with Flashtool
- Flashed DooMLoRD's CWM-Based Recovery 6.0.3.2
- Installed AOKP MR1 Milestone 2 (Android 4.2.2) and used it for a couple weeks
What I did trying to solve the problem:
- Wiped data/cache/dalvik cache
- Flashed various stock brazilian ROMs through Flashtool (10.3.A.1.434, 10.3.1.A.2.67 and 10.3.A.0.423) countless times
- Flashed AOKP again
- Restored to 10.3.1.A.2.67 using Sony Update Service (had to relock the bootloader with Flashtool)
- Tried updating using Sony PC Companion but it said I'm already in the latest version
- Tried to use Sony Emma but I can't get login credentials (I'm not receiving the confirmation e-mail)
I followed some instructions for similar problems in the Q&A forum but most of them end saying the owner had to send the phone to warranty, but they never say what's the outcome...
Do you think I'll have to do the same? If so, is there anything more to before sending it, other than relocking the bootloader and flashing stock firmware?
Thanks and sorry for the lengthy thread

Is that right? Whe should start a new thread with symptoms like Upgrades, model version of the device AND chargers used lastly ( still thinking that's not the problem )
PD: Luckily I'm getting a new battery( used actually, torn apart from a totally destroyed device ) in 2 days from now and check if that's the real problem.

[Q] Xperia ZL Only Boot Up While Charging

Hi all!
I have ZL (ZQ in Brazil) and about two days ago it simply shut off while I was taking a picture. The phone stuck in the first screen showing the Free Xperia logo and didn't come up until I plug in the power (from wall or pc usb).
Today I've dowloaded the last oficial firmware from sony and put it up via Flashtool but now, as soon as I take the cable out the phone dies.
I noticed that with the oficial ROM, when it finishes booting up, I receive the message: "com.android.phone has stopped.".
The phone also looses the signal in places it use to have full bars, like my room...
Before that my phone was ok.
*All off above happens with battery full charged!*
Also, I did a snapshot update a few weeks ago and several features went off (I thought it was a stable version since it showed up on cyanogen menu). So I tried to recover the last version via Cyanogem menu. The phone stuck in boot loop. Then I downloaded the version again and installed via CWM.
The thing is that I never notice nothing uncommon since that day. I don't know if it's related.
Does anybody knows if it's software/firmware related or does it have something to do with hardware issues?
Any help is appreciated!

This problem is now spread in most of ZL user and many thread is addressing this issues ass well...
This is probably a battery or battery management issue...you need to send to Sony servise center for replacement or repair...
Or you can do it on your own by changing the battery...no software can solve this problem...
Hope for the best...
Press THANKS if this help...

Stuck with the same issue here !
Hi all,
Everything was fine until yesterday my phone switched off during a call and never switched on.
Now it switches on only when connected to a wall charger ! Please let me know if someone fixes this issue

I'm also thinking it's hardware related
Since mine is only 6 mo I'll take it to an authorized repair shop tomorrow morning.
I let you guys know if they find something out.

Just back from service center
The Sony service guys could not make it work after a software overhaul.. They are gonna replace the entire chipset to fix the issue ! and in warranty :victory: !! Though Still no idea what caused the problem in the first place!

Exactly the same problem over here buddy...
Here's a little something I wrote to Sony and their Press people.
"I've purchased my Xperia ZL in the United States (online at the end of March 2013 at ATGSM.com) and started using it mid April, 2013. I currently live in Brazil.
After using this phone normally for about 9 months, there was this one day back on the first week of January 2014, where I was taking lots of photos at the world famous "Serra da Capivara National Park" and could just feel the phone heating up like never before. Next thing I know, the screen went blank and phone would not respond when I pressed the power button.
I had to pres the reset button in the back of the phone in order to make it work again. But once I tried to load the camera app, the phone would automatically shut itself off. I thought it could be related to a faulty or corrupted External SD Card, so I went ahead and removed that as well before I attempted to turn my phone back on. After the system loaded up again I tried to oped the camera app and the phone turned itself off again. Any app that would require a significant amount of processing power would cause the phone to freeze and shut off.
So I decided to charge the phone all the way up until 100% (while powered off). When it reached 100% I turned it back on and used it normally (while it was still plugged to the wall charger), so I thought... Great, the phone is "OK again"! Then I went ahead and unplugged the phone off the charger, expecting it to function normally... In just a matter of minutes, with just a little bit of usage (checking emails or browsing the web) the phone simply shuts itself off on its own, yet again. I tried to turn the phone back on again and just as before, I was greeted by the Sony logo and - without any warnings or alerts - the screen simply goes blank again and that's it. This is all it does on the battery.
I've searched online for a solution for this problem and I got nowhere. My phone is all stock, bootloader locked, not rooted. I've formatted and updated it with the latest Firmware (10.4.B.0.569) a couple of times using Sony's Update Service application for Windows to no avail. Nothing seems to fix this battery/shut down on its own problem. There's tons of other Sony users complaining about similar issues with their Xperias. Just look up "xperia zl shuts off" on Google and you'll see what I mean.
My phone is one big dud...
So there you have it - one big useless US$650 piece of hardware. That only functions normally when it's plugged into a wall charger or your average computer USB port.
Not much of a "mobile" phone if you ask me.
I'm extremely unhappy with Sony's hardware and their inflexible technical support.
I've purchased this device in the United States and they can only grant me tech support under my 1 year manufacturer's warranty if I ship it over to their facility in Texas for repairs. That's no big deal for me. The one big problem is: They want me to have a US shipping address so they can ship if over to that address after they finish repairing/replacing/refurbishing my phone. And I've got a big problem with that.
I do not live in the United States. How am I supposed to pick my phone up over there?
After doing some digging through my phone's IMEI, Sony's tech support representatives brought to my attention that my device is a "Grey Market" phone (meant to be used in Singapore?) and that they don't even know how long it will take for them to service my phone. According to their supervisor, it could take anywhere from 1 month up to 4 months, maybe even more for them to repair and send it back to me.

Solved (by myself)
As I said before, I lost my warranty the moment I unlocked my bootloader and they were charging me almost the price for a new phone.
The only place I found the batery was on ebay.it and took more than one month to arrive.
As you all suspected, changing the battery solve the problem.
The only problem is that now my camera doesn't work...

Thanks anyway. I hope it helps if someone else have the same problem!

I am going through the same excruciating process with my girlfriend's Xperia ZL right now. This phone has not been rooted and just kept running the official updates from Sony. I just updated it to their official version of 4.4.2 and am having the exact same issues. The phone crashes, freezes and won't stay on and can't be kept powered on unless it is kept plugged into the wall or computer USB. Just got off the phone with a higher-level manager at Sony who was "sorry" and "couldn't do anything" unless I pay for the repairs myself. They were actually blaming Google for releasing a "bad" update which he said was "affecting ALL android phones". That's a pretty bold statement- especially knowing that's false, reading all the threads online about this issue with Sony devices specifically. This was until he found out that they screwed up and realized the phone was still under warranty, expiring TODAY. After an hour of back-and-forth, I got him to agree to paying for shipping and fixing the phone as if it were under warranty status still.
I will never buy a Sony piece of hardware again and will highly discourage and demote their hardware to anyone.

[Q] LG G3 Turning Off Problem

I have randomly started experiencing a problem where my device would turn off randomly which has gradually gotten worse to the point where it's stuck in a boot loop sort thing and will shut off randomly during boot then restart.
The problem started by every now and then (sometimes not happening for a day at a time) the phone would turn off then turn back on again gradually getting worse. The problem started when I installed the latest update during the update the screen froze (no it was not interrupted in anyway and done officially through the phone) so after leaving it overnight and it not progressing I took the chance and removed the battery. it then turned on and finished the update without an issue. The phone has since as I explained got into a 'boot loop' sort scenario where it will work if the charger is plugged in but couldn't be a battery issue as doesn't turn off if I put it into download mode. Things I've tried: Doing a complete reset- Still no fix. and now today I entered download mode and re-installed the firmware which was successful but still no prevail?! What the hell could this be?! Thanks

hi, where did you get the firmware? it could be corrupted. if I were you I would download again the firmware and reflash it.
after that I'll do a hard reset.

Well i guess im not alone as i have the same exact problem as you do! WHich version do you have? I have the White T-Mobile version and i bought it the same week it was on sale i felt that i got a phone that was part of a bad batch because of some problems ive had with it but i didnt buy insurance for it. i was on LG's OS and it started to get worse and worse so i restored it and went to a lollipop rom. its still happening but it only reboots once. however, as soon as i start using apps it reboots on me. i want to unroot it but at the same time i dont want to go through the trouble of rooting it again. Any ideas of what it could be?
My problem just randomly started happening and i noticed this started happening strangely after my phone completely died on me and didnt want to turn on so i connected it to the charger and it started charging but had a yellow warning triangle somewhere on the screen.

Hey, nice to hear someone has the same issue, I however hvent had the yellow warning triangle come up yet, as an update all of a sudden it keeps turning off as soon as it boots even on charge!!!??? It just keeps getting gradually worse?! However I have noticed the battery % it shows when turned off is 100% and very randomly it displays 70% then when the phone boots it will show 2% for the 2 seconds it stays on before it dies?!

Wait now it reboots on you even if its charging? I too started noticing that with my battery . if I turn it off and charge it it and lets say it says its at 75% well I turn it on and its like at 40%? I really don't want to buy another battery but I actually hope the battery is the culprit. There's a guy with a G3 in my school I'm going to see if he let's me try his battery out on my phone I'll keep you posted

Hey sorry for taking so damn long on replying i've been busy studying for some exams.
I've got good news for you though, i took my phone in to T-Mobile and showed them my problem. Without me putting much effort into persuading them, they shipped me a new phone, and no i didn't pay for insurance on T-Mobile, this was covered by LG's 1 year Manufacturers warranty!
Anyways, I received the device but did not receive a battery. So i tried my battery on the new one and what do you know? SAME PROBLEM!
So yea you should either try to unroot the phone and take it to the store but don't mention that you think its the battery, they'll send you a new phone! Then just buy a battery online or call them after a few days and say your problem is still occurring with the new phone and see if they send you a replacement battery, im a little skeptical on this second option as id rather keep this new phone haha

Hi, even i am having this problem, my phone is a D855 and in my country (Mozambique) i am not using a contract so its different than US, we have a LG store here but in the LG website our country is not stated. So only way is to go to a trusted Store that repairs phone here. My question is that, when its not connected in the charger it just keeps reboting (the notification LED doesnt even blink) infinite times. At first i thought it was a software but after going from Stock to Cloudy to CandyRom the problem was still there. Then after i plugged in a charger the phone would succesfully boot up and i could use it normally but had to stay connected on a charger. So what have you done to fix this? Did you replace the battery with a new one and then it stopped rebooting?? Please help me as i want to buy a new battery but first want to confirm if its the battery at fault....

Hello buddy, sorry for taking so long to reply. Im usually not on XDA too much. Yes i solved my issue with a new battery. I tried my bad battery on 2 lg g3s and it rebooted both. I also unrooted my phone and flashed a completely stock update and was still having that issue.
I hope my response isnt too late for you!

No problem bro! Got a new battery and do far my phone doesnt reboot, but the only problem i am having is that my phone shutsdown at 30% battery and when trying to turn on it says it has 0%

Im having the same problem gotba new battery and no different so annoying

Best thing just happened. I had the G3 for a while and my first one had an issue and had to get a warranty replacement. Long story short... I got two more G3s from T-Mobile that were defective and most carries have a policy where if you get 3 warranty replacements you can chose a different phone. To wrap it up, you can ask for a phone of equal or lesser value when purchased from the carrier (I bought mine off eBay and they didn't even notice, I spoke to several reps and no one caught on.) So they can either send you a whole new phone, a new battery, or in my case: I received a new LG G4 since I had gone through three which pretty much anyone can do with a bad battery.

Guys. Im having this same exact problem on my LGG3!!!

Expired Battery or Faulty Power Button could be the culprit
This issue just started happening to my LG G3 over the last 2 weeks. I've had my LG G3 for exactly 15 months and all of a sudden it started cycling endlessly and if it did get to my locked screen and i tried to unlock it it would just restart again.
I found that when I plugged in the device to a wall charger or high power power brick, it would halt the reboots but otherwise it would get stuck in an endless cycle of partial reboots (when it did stop after plugging in, I would find all my apps still open and waiting for me, so they weren't real power cycles).
One of my coworkers has a newer LG G3, so we swapped batteries and immediately he had the cycling issue on his phone and with his battery in my phone the issue vanished.
On closer inspection, my battery was a few months past its expiration (FYI to anyone with a LG G3 - your battery will expire more or less exactly as its warranty protection does!), so went and bought a new battery and everything is fine now.
For those of you who have tried replacing the battery and find it still occurs, another coworker said his wife had a similar issue on a different device and it was resolved by having the power button replaced, so it is possible that this could be a factor also and you should have your phone sent in for inspection/repair.
Hope this is helpful for some of you.

I've had the same issue since February, when my phone was about 17 months old. It kept turning off saying SIM card not detected. I tried replacing the SIM card and washing that area with alcohol with no luck. Then I replaced the battery with a second one that came with the phone which I'd never used, but I noticed no difference. It also has no phone service for several hours without my knowledge. LG just told me to reset the phone, but it looks like that doesn't work from what I've read. T-Mobile said they'd give me a new phone but there are no G3s in stock and offered me a Samsung 3, which is three years old, so I am worried that it won't be able to handle the software updates. It's ridiculous that a phone that costs this much won't even last long enough for me to pay it off. My last phone was an Iphone, which I had for more than four years.

I had the exact same problem a few weeks ago, posted a detailed explanation of the problem and got 0 replies and a few hundred views (thanks guys!)
Easy answer:
Replace your battery
Thats what I did, and the problem is now gone. When you do get a new battery make sure you drain it completely first, then charge it for 4 hours without exceptions.
I tried factory resetting, installing a new firmware, going to stock and going to custom but nothing worked.
The girl in the shop where i bought the battery surprised me, i just asked her if they had one available and her immediate reply way "why, is your g3 stuck in a boot loop?", apparently EVERY SINGLE PERSON that bought a g3 battery from them had the exact same issue.
Now the problem is gone, and my phone actually lasts longer than before.

Hey, I am having the EXACT same issue. LG G3 was stuck in an endless loop, replaced the battery, now it works down to about 30% and shuts off. When I try to restart it says 0%. I even tried a third different battery, and still getting that 30% shutdown. Did you ever figure out what it was? I am wondering is it something to do with how the phone reads the battery charge i.e. does it think the battery is dead when it gets to 30%? It has e stumped!! Any advice would be most welcome. Thanks.

wtf,actually same with my LG G3,after when I bought a new battery. Shutsdown at 30% and it says has 0%.

same problem
