CAUTION

I request users to please check the screens closely of their Xperia ZL. Disable the "auto-brightness", keep the brightness to maximum and set the screen time out a little higher say 5 minutes. My Software version is 4.2.2. The screen FLICKERS. I had my previous Xperia ZL exchanged because of this problem and the "new" phone has the same issue. I am currently having a miserable experience with Sony and their service centers here in India. My previous ZL had a motherboard problem and I am not totally sure if the "new" one is really new or the old wine in a new bottle. If things persist like this I'll probably head to the consumer court.
Any inputs will be greatly appreciated.

Then surely it's a case of me being conned.

No problem on mine either. Please do note that there have been some reports from Z/ZL users having screen flickering experience after upgrading to 4.2.2.

Hmmm the problem seems to come and go. But my previous ZL had a motherboard issue as confirmed by SONY. As I'm typing this message, there's no flickering at all. I am confused. I want to get things right within the warranty period.

Yes, it is very frustrating. Some just restart their phone and the problem is just gone. Some experience the problem again after a few days. And not many people have this problem. So, we can't tell right now if the problem comes from the new firmware or from the hardware itself.

When I keep brightness full n that brightness slider is on screen it flickers once while rotating the screen.. When I remove that brightness slider n go to main settings menu no flickering occurs also when auto rotate off no flicker...i thing but I never use full brightness n moreover it flickers just once before rotating so I guess nothing much to worry.

Thanks everyone..
Hmm btw another question, the replacement unit I got comes loaded with those wallpapers one usually sees in demo units. Here, the ones in the last few rows. Please check this link :
http://forum.xda-developers.com/showthread.php?t=2152482
And is it true that it's not possible to get a SIM running in demo units? I am able to make and receive calls but, for some reason I'm getting a feeling that the replacement I got is a demo unit. The IMEI number on the box and that of the phone are the same but the box does not contain the charger, earphones and the USB cable.

BTW, what I mean by flickering is CONTINUOUS faint flickering of the screen. On the entire screen. The screen shivers!

Yes only the phone was replaced by them. But, the flickering comes and goes. I am having a horrible time here. Is there any chance of a refund? Worst case, I will ask them to give me an XZ as I have lost all faith in ZL anymore.

Every xperia has a demo installed in the phone..it has a demo folder somewhere inside the internal memory which contains the video demo file I foud out when I was exploring the internal memory n there is some code to activate demo on the phone all phones so no need to worry abt that n regarding only getting phone...its policy that company will exchabge obly things that u have problems with...since you had problem in phone and not in accessories so they sent you only phone nothing much I myself got replacement for faulty led indicator n they replaced only phone...

I have done all possible things from my end. My first ZL had a motherboard problem and after much argument, I got the replacement which isn't any better. They initially wanted to replace the motherboard only but I rejected it. I had asked for a completely new phone.
I usually keep the display at "auto". But now, I have kept it at "max" to check if the flickering occurs. It comes and goes. I last saw the flickering today morning. I will ask for a refund since I cannot keep a faulty product. And, I agree with you about ZL>Z in many aspects. This phone fits my requirements perfectly but what I have been going through over the past few days...a real nightmare.

i understand your problem like you i am too a little touchy about my devices faults..then its better you directly demand talking to one of the executive manager. bt sad to say ,i dont think they will refund.and this time if they exchange ask a sealed box.

It's 100% related to the 4.2.2 update, so be comforted it's not in anyway hardware related. This was one of the primary reasons I downgraded back to 4.1.2.

The problem is temporarily solved with a fresh install of the 4.2.2 update and then randomly comes again. I do not know what to do. I am forced to run to the service centers time and again. Is there any way to downgrade to 4.1.2 without losing the warranty?

Yes, you can downgrade back to stock 4.1.2 firmware, many of us have done it (flickering was one of biggest reasons). It will keep your warranty 100% intact since the bootloader isn't touched. Remember, only unlocking your bootloader voids your warranty, and you're not doing that here. You're simply using a 3rd party tool (Flashtool) in place of Sony's PCC/SUS tool to flash a 100% stock Sony ROM.
Just follow these instructions I posted last week: http://forum.xda-developers.com/showthread.php?t=2342680

[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...

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.
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 I less than 1 month after they received my defective products, 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.

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.

Sudden power off solved with new battery !!!

Finally tested it today and it really works!. The real fact is on web you always find that "it should" be the battery, and a battery change "whould" solve it, well I have to try it and it really does, so you should get a battery somewhere ( check out I found 2 places on www, dunno if I can put the links please say If I can do so ) and get your phone alive again! ( I'm so happy :laugh: )
Here are 2 dissasemble videos; one from our friend "danieldp1990" and one in russian HD. Whould reccomend use both of them since as nice as the russian video looks, they're missing some parts.
The most hard part is to remove the battery since it's glued and you don't wanna do much strenght since you have the display right below it, so make it slowly.

My Xperia ZL just started doing this sudden shutoff thing but it seams to be getting worse, it's gotten so bad that when you boot up the phone it shows the SONY logo then immediately shuts off. When I plug it into the wall charger the LED lights up RED and then the SONY logo then reboot over and over(Bootloop). But yet i'm able to get it into fastboot and flashmode fine and can flash ftf through Flashtools with no problems i'm wondering if this could be a simple battery problem or if it's a software error. If anyone could help it would be greatly appreciated.

There are loads of posts about this issue on Sony's official forum. Looks like you either have to send it to Sony or put a new battery in.

I finally replaced the battery in my zl, and it fixed the issues of not powering on. But the new battery appears to be having issues. Sometimes it went charge. It will fluctuate percentages, for ex it would go from 58 to 56 to 60 to 55 etc.. It's been acting crazy. Even on various roms. I restored an old backup of miui I had, and it seems more stable, but still won't charge full. The replacement battery was a Sony oem one so I'm not Sue what's up.

It WILL fix it.
Sudden power off, Not powering on unless charger attached, missing signal/signal problems, ultimately not even powering on with charger is the whole same issue = Crappy Sony battery ( programmed obsolescence )
Now it's happening again to me. Will NEVER buy a Sony product again in life.

But yet i'm able to get it into fastboot and flashmode fine and can flash ftf through Flashtools with no problems i'm wondering if this could be a simple battery problem or if it's a software error. If anyone could help it would be greatly appreciated.

Xperia M5 Auto Shutdown Fix (temporary until official fix)

(alternate fix)
hi, guys!!
This is my first post where I will show you how to fix the
Auto shutdown problem until we get an official fix from
Sony.
Let's start:
Go to the Dial pad and type*#*#3646633#*#*
This will take you to engineer mode
Now go to Bandmode>SIM1 and unthick EGSM900, GSM850, WCDMA-GLR-850, WCDMA-GSM-900.
Now click set and that's it.
You may experience worse reception in places with bad reception but atheist you will be able to use your phone, that's why it's a temporary fix. I have been using this method for one month and it has worked.
I'm not an expert so if I am wrong in something please correct me ?

I forgot to mention that if you have 2 SIM card repeat the process on the second one

Just FYI, there's already an official fix, it's going to a Service Center to get your faulty battery replaced by a newer one without the issue. If you unit was manufactured in 2016 then you already have the new battery and are exempt from the issue, if you got your unit in 2015 and are experiencing random shutdowns, the warranty should cover you...

Yeah, I know but some people just don't have time to leave their phone in costumer service for minimum a week besides this method works pretty well.

Besides I bought my phone in January and I got this problem. I have taken it to the service center 3 times where they changed the battery 3 times.

I said units manufactured in 2016, not units bought in 2016 (e.g. there's still a small chance of getting an unit from an old stock manufactured in 2015 even if you buy it nowadays, depending of the store/seller/etc). Taking into consideration that you got your unit in January and also have the issue, it's pretty likely to be from an old stock of units manufactured in 2015. You can check the exact manufacturing date by looking at the sticker present inside the SIM/SD card compartment, mine for example marks 16W04 (aka "manufactured in the fourth week of 2016") and doesn't have the issue, I never experienced a single shutdown, not even when doing the testing procedure to check if the unit was affected by Battery Lock issue.

Hi. Its Dk.
I am the one originaly posted those soltution on xda and gsm arena.
In real, if you get the battery replaced, you will suffer from permanent overheating and slow charging. Also, it takes 3 weeks to replace the battery by freaking noob sony service centers.
It also aplies on the phone manufactured newly
Now i am tryng the new way and its been working 6hours without shutdown and turning off frequency.
Be patient, after organizing, I will post the new way

It can't be the software my phone never turned off not even once,no random reboots,nothing.Only thing is that it heats up when playing some online games but nothing so much after i'm done playing and leave it for cuple of minutes without using it and it cools down to the normal temperature...

I guess you are in good network condition, full of signal strength , even wifi.
Then you wont feel anything from this problem... and the shutoff problem is not only on m5,
almost every sony xperia series. even z5.
and basically, the phone turns off because of supply voltage. its rare to happen on battery as worldwidly.

Not really,everytime i get inside of a store my signal drops and the phone still doesn't reboot or "die".I even tried the test and it passed.

When your signal completely drops, you wont have overheat and shutdown. Because the phone wont even try to get the good signal.
But when you have subtle signal strength, the story changes.
CuZ the phone stays in the idle state for better signal strength.
Im testing with fast dormancy disabling. But not sure yet.

As a person who personally owned a Xperia M and is now owning a Xperia M5 and that also had close contact with Xperia S, Xperia U, Xperia C, Xperia ZL, Xperia E3, Xperia Z3 and Xperia Z3+ I can safely say that what you're claiming here is bullsh*t. There's one operator in my neighborhood that always have very poor signal (never more than one or two bars in network indicator) and those models I mentioned earlier NEVER shut off at those conditions, at maximum they got a little warm during huge data transfers (e.g. downloading/uploading a big file over mobile data) and nothing more.
Particularly with Xperia M5, there's the now known battery lock issue (even Sony officially acknowledged this). If your unit was from an earlier batch (generally manufactured in 2015), it may randomly shut off, not because of supply voltage, but because of RF interference: the battery on those models has poor shielding, which triggers the issue (you can get a free battery replacement just by going into service center, which will completely fix this issue on affected units). However, if your unit was from the new batch, manufactured in 2016, you're totally exempt from this issue. My unit, for example, was manufactured in 2016 and it never shut off randomly, nor it triggered battery lock issue (I can do the official testing procedure thousands of time and it always pass without issues). To be honest, until now I've never encountered any user with a Xperia M5 unit manufactured in 2016 having this issue.
And if it this "shut off due poor signal" issue you're claiming REALLY happens on "almost every Xperia series" why I can't find not only a single complaint when going into the forums of other Xperia devices, here at XDA?

GSM Arena isn't the world either. But since you've mentioned GSM Arena, let's talk about GSM Arena, going into User Opinions about Xperia M5 you can see lot's of posts complaining about random shutdown (the known battery lock issue) but all of them made in 2015 (in other words, users from the first batch, which had the RF interference problem). You can't find a single post from 2016 about battery lock issue. And continuing on GSM Arena, I also visited User Opinions from the phones I mentioned earlier and didn't find anyone complaining about random shutdowns like you've claimed.
So, yes, what you've said before still makes no sense, like I said before, bullsh*t...

Hey mate. Then you think battery lock issue is separated from autoshutting down?
So 2016 manufactured phone has got something different other than battery.
But i think battery gets locked because of autoshutting down. Since my phone does show different battery percentage when autoshutdown happens.
And if 2016 manufactured phones have replaced battery, why would i see somebody still gets the problem after they have replaced their battery?
Its may of 2016 already.
So to finalize it, we can guess few situations.
1. Replacing phone battery only works in certain region. Which means sony hasnt fixed the problem.
Or
2. Its not battery issue. Sony put something else in new manufacturing.
3. Those comments are lying to disturb sony's income.
So its the why i cant trust your opinion that 2016 phones dont have the problem.
Thanks.

Change the Battery

This fix work for me, but the problem is the signial, i none.
So i change the battery and is working pretty well, i have two weeks without auto shutdown problem.
PD: My terminal was bring from China.

I upgraded to build 30.2.B.1.21, and I realised that Engineering Mode is gone! Now I can no longer apply the fix.
Shame on Sony for doing this!
