Do it for your own risk

I´m afraid that this thing is the right work to fix that problem, first nobody has this schematic, and has someone that knows what are happening with temperature, current and voltage mesurements? I have seen for years some sounds about cells that can explod and other that has exploded, It´s too risk. Pay for this in a authorized service repair. You should be carefull with some miraculous news.

Yes. I am also concerned about the safety and might try this approach(or get a new battery, unfortunately, it seems that sony does not sell official xperia ZL battery, and no name batteries seem as risky as this approach) as my phone is showing similar symptoms.

However, going through the original solution given by rivera_696(post #6) seems safe enough because -

1. Its difficult to come up with random solution. Somebody must have thought about the actual problem and then decided to try this out. This does not seem like an ad hoc fix out of nowhere.

2. As rivera_696 said, problem seems like - flex cable is not connected correctly to negative terminal of the battery. If you look with attention, its clear that battery is connected to the black strip at 2 locations - 1st is on the left(silver one), 2nd on the right(black one). OTOH, there are 3 distinct blocks on the cable towards left(refer the original photo on page 1) Now, I am willing to believe that these three blocks are for +ve, -ve and ground. Ground would be provided by phone hence it is NOT connected to battery. So out of this, -ve connection of flex cable with actual battery -ve terminal seems to be messed up. This cable is just making sure that this connection is working. Now if flex is faulty, phone should not start at all, but that does not seem to be the case as SONY logo still appears on screen.

However, when on charger, battery is bypassed and hence all things work ok.

Also, if this is so easy and possible then why SONY is not doing this, by charging small amount? But then on the similar lines, if this is battery related issue, then why dont SONY just replace the battery with new one many people have solved it this way too? So, I feel that SONY is just lazy and irresponsible here and actual solution to the problem is simple.

This does seem logical to me, but I myself have not opened the battery yet. If anybody has, can they confirm this? Can somebody see the small lines on the battery flex cable/visually inspect connections and see if it supports the above logic? Simple multimeter should be able verify this too.

I think rivera_696 can explain this(or check on the original source) but not sure if he is active.

Thanks guys for sharing your thoughts/experiences/solutions :good:
[Sony Xperia ZL] katananja:
It disables the battery thermal sensor that avoids the battery from exploding. There's no software or firmware that will fix this, is necessary to send the device for service, there a real technician, will replace the battery.
[Sony Xperia ZL] TechnoFreak750:
the problem is caused by overheating and the negative terminal of battery got defused.. you need to eighther replace the battery or to bypass the negative terminal through a jumper wire.
[Sony Xperia ZL] cemgramas:
Thanks!

Thank you Israel, was already up looking for a new phone. I made two weeks ago and so far no problems.

Muito obrigado Israel, já estava até procurando um celular novo. Fiz há duas semanas e até agora sem problemas.(inglês do google tradutor, sou brasileiro)
[Sony Xperia ZL] givemered:
Was able to resolve my battery issue. I had ordered battery from China, but was able to replace it locally.

Sony refused to repair and instead offered me refurbished Z1 for 13000 rs without accessories. If they would have given box pack I would have gone with replacement, but I rejected it. Also Z1 seems to have many complaints regarding screen self cracking.

I tried to repair it at home but there was one screw which was not opening even with lot of force. 0 number Philips screwdriver slipped and made the screw head + into O so was not able to open it at home.

Was skeptical while giving phone to local store as I feared they might mess up something. But in local XOLO repair store, they replaced the battery for 1550 rs. Also gave me the older battery. Like I feared, they were not very careful and forgot to fix all the screws and lost the USB latch, but I was vigilant, so found that out and got screws and USB latch fixed.

Now phone works great! Happy that was it revived with little money. But I hate Sony for refusing it for repair.
[Sony Xperia ZL] rohan.xda:
Thanks bhai i also have the same problem and i do the same thing connect negative terminal of battery with wire and my phone and battery this time work perfectly.
[Sony Xperia ZL] cooldude94:
My battery is giving me this trouble. Is this procedure safe?
[Sony Xperia ZL] CokeJunkee:
Well, if you bypass any kind of security electronics that was built to keep a battery from physical damage (like thermal sensor, charge monitor, etc) the system won't be safe anymore !

Yes, it will probably work on most devices with that special battery problem.

I tried it myself and it worked. _ But IT IS NOT safe. _ I didn't really like walking around with a potential time bomb in my pocket..

:eek: :silly:

Edit: Have you ever seen a burning LiPo.. ? :D

.
[Sony Xperia ZL] cooldude94:
so what did you do did you buy a replacement battery or another phone?
[Sony Xperia ZL] CokeJunkee:
I bought a new battery after a few days.

It's easy to replace it. Just some patience and the right tools.. ;)
[Sony Xperia ZL] hexabytecampinas:
And the new battery solve the problem?? :confused:
[Sony Xperia ZL] CokeJunkee:
Yes, replacing the damaged component solves the problem..
[Sony Xperia ZL] OllypopZA:
I had the same problem. I purchased a new battery and replaced it. But the new battery didn't last long before i started having the same problem again. So I sent it back and got a refund. I used the method posted earlier on my original battery in February. It's been months and I've had no problems since. My battery capacity isn't what it used to be the past few days, but it is 2 and half years old. So I'll need a new battery in the future, but if you're reading this and you're skeptical. Don't be, it really does work. And it hasn't exploded.
[Sony Xperia ZL] chherr:
I had the same problem - phone shuts down. I replaced the battery but that did not solve the problem. Another issue - I installed XZDual Recovery and booted into recovery. All fine but after the next crash recovery was lost... :mad:

Do you think I should give this soldering trick a try ? How fast will that phone burn ??? :confused:

Best, Christian
[Sony Xperia ZL] chherr:
Great work

[MENTION=5450408]rivera_696[/MENTION]

Great work you did ! I had the same problem and was not sure if bridging some circuits with a cabel would be healthy for the battery, the phone an me :confused:

That's why I bought a new one. After install the new battery behaved as bad as the old one. Finally I did what you suggested but wiht my old battery - and voilá... I'm back on my Sony again. It works flawless. I even stressed it a bit and installed all my apps again while on charger after system upgrade to 10.7.A.0.222 which gave me 45°C of battery temperature. It seemed the device then stopped charging for a while and got slower until temperature dropped to about 40°C.

Concerning the general behaviour - I'm not sure if it is the battery flex, because it happened with new battery, too. But in the end my sony is working again - with build 10.7.A.0.222 :D

This is really good news.

Thanks again.

How repair a board that stops to charge after that proceredure , doesn't works with me, times ago it's charging and power ups sometimes, now it's heating whem put to charge and it has just 0.08V on battery terminal, curiously on the tabs are 4.0v , Does someone can help us?
[Sony Xperia ZL] nandhul30:
Its worked.....:D

its worked perfectly for me....thanks brother..u r awesome
[Sony Xperia ZL] Govienda:
Thanks a lot

Had same problem, bought new battery, Still same issue. Then I found this and went immediately for this solution. Now working fine. Thanks

Can you explain me what was the problem exactly? and how you found this solution?
[Sony Xperia ZL] anagramgenius:
Thanks man. Working fine so far.
[Sony Xperia ZL] JetOoi:
Thanks . This additional wire method worked for my phone. Just fixed it 10 mins ago and will keep monitoring. Hopefully wont explode..:p
[Sony Xperia ZL] tomchim:
try to answer

guys this method can explain very simple,sory i can't make a pic of it,,in other words our battery have 3 conectors +,neutral,- (plus, neutral, negative) in this case our flex cable because of heat problem or move has loss its cappability to connect it,,this jumper just connect this Neutral with negative side of battery, in case why this phone should be connected in charger our sony Phone can by pass battery from outside power external,,in old sony device if we connected to charger and you pull up the battery it can still allive without battery but from power external just like laptop or notebook so nothing to worry

just smal piece of me CMIIW
[Sony Xperia ZL] random_n00b:
Thanks for the tip to solder the battery. Just did that, and my phone is working again. :) :good:

But I have a question: What is different now compared to a "normal" phone?

From what I understand, the soldering bridges (=disables) some electronics that protects the battery from under-/overcharging.

Can I still leave the phone plugged in the charger and it will stop at 100%. Or will it just continue to charge >100% and damage the battery?

P.S. You can find a very good tutorial here.
[Sony Xperia ZL] random_n00b:
After the battery repair, my WIFI connections are all very weak (only 1-2 bars) even when standing directly at the router. :(

Something with the WIFI must be broken.

Can anyone tell me which component is the WIFI antenna?
[Sony Xperia ZL] chherr:
Hi,

my son uses the phone now and we encounter no problems with the modified battery. WIFI is still ok with our phone.

Best, Christian
[Sony Xperia ZL] tsynik:
Have partial success with this method: after soldering wire phone boot normally (it wasn't before mod) but it will turn off itself on final phase with this dialog:

E/BatteryService( 1257): silent_reboot shutdownIfOverTempLocked

...

I/ShutdownThread( 1257): Performing low-level shutdown...

so firmware think battery is overheated and turn off itself. Probably I need new one ;)
[Sony Xperia ZL] umhhmm:

Please Help

I have a brand new SPV M5000 from work. Set up to get email with exchange server for emails diary etc. This works fine. In the Comms Manager wifi will not turn on, to be clear this is not about connecting to a wireless network, wifi will not ven turn on. 3G etc all fine, but wireless will not activate.

Orange seems stumped, previuosly it did work ,according to my IT manager before the sim was activated. Since then no joy. I have hard and soft reset to no avail.

Can any of you throw a light on this?

I have lookd through the other messages on this forum and cant find any mention of it

Thanks in advance.

I have a similar problem on my universal. Any ideas from any one on how to fix it ?
[JASJAR, XDA Exec, MDA Pro General] Krazy2005:
I've been having the same problem. sent it back to O2 they fixed it twice and it is still being gay!

Please please please somebody help me!
[JASJAR, XDA Exec, MDA Pro General] ighorsey:
My XDA Exec started off fine, and then over time it took more and more attempts to connect to a wifi service. I recently sent it away to have the USB port re-attached, and since then it won't connect at all.

I have upgraded the ROM and it hasn't made any difference.

Does anyone know if there is an aerial for the wifi electronics? Could it be broken? Is this more likely to be a firmware / software issue?

Any clues would be gratefully appreciated.

Thanks

Ian

[LG G Watch] Derekwolfee:
Looked at my watch and noticed the time was about an hour off.. The watch is completely frozen. I've tried placing it on the charging dock, also pressing the reset button for up to 30 seconds. And looking within the android wear app for a restart option all to no avail. Anyone know how to restart it?
[LG G Watch] ckarrow2:
Is the display still on? Maybe once the battery dies you can get it to reboot on the charger. Keep us posted!
[LG G Watch] dersie:
I also frozen my GWatch 2 days ago and I restarted it after push the reset button for 10s.
[LG G Watch] Derekwolfee:
Yes the display is still on. I was hoping to not have to wait for it to die.. Ugh but thanks!
[LG G Watch] Derekwolfee:
Solved (well kinda): letting the device drain the battery over night and when I woke up the screen was black.. Placed it on the charger and all seems good now. I just wish there was a way to restart it without having to let it die.. Luckily I was home all day yesterday.. But if it would have froze while I was at work I would have been without it all day. That's kinda scary because I need a watch at work in my profession.
[LG G Watch] dude1981:
Look on the back. There is a hole where u can stick a paperclip or something same in to reset
[LG G Watch] Radagast82:
my watch seems died. Left it on the charging cradle all night long, this morning i found it off with no way to turn it on. Placing on the cradle again shows the full battery icon, but the screen is totally black. Tried to use the little button on the back of the watch for about 10 sec with no results... any suggest but rma?
[LG G Watch] Derekwolfee:
I tried the reset button. Its in the op but thanks.
[LG G Watch] Derekwolfee:
Maybe try letting the battery run dead? That is what I had to do in order to get mine to reset
[LG G Watch] Radagast82:
the thing is, seems like the watch is off, so i guess it won't go out of battery...
[LG G Watch] Derekwolfee:
Can you take it in a dark room? Is the backlight on?.. If not then yeah I would try returning it where you purchased it. :(
[LG G Watch] Radagast82:
backlight seems off. i'll try again with the cradle once i'll be back home, but i do think that rma is the only way :(
[LG G Watch] Radagast82:
update: seems like the charger i use no longer charge my gwatch. I connected the watch to my pc with another usb cable, and after some seconds it boots up :)

battery was completely drained (0%) so that's the cause of the problem. now, i tried to charge my phone with the same charger i use for the watch and it seems ok, so i'll probably have to discover why it didn't charge my watch until battery gone 0%...
[Galaxy Note 3 Q&A, Help & Troubleshooting] jw2153:
Hello guys! I purchased a dual sim Galaxy Note 3 (Chinese Unicom version) from China, an SM-N9002 running 4.4.2 KitKat. I want to root it to flash gapps and Cyanogenmod. However, after countless attempts at rooting the phone, none of them seem to work. They all seemed to throw my phone into an endless boot loop, that could be fixed by going into download mode and hitting cancel. Even after the boot loop, I do not have root access (I checked with a terminal emulator apk). No root seems to work, not even towelroot. This obviously means that the phone has a locked bootloader. I am not sure what to do now. My goal is to get root, flash gaaps and Cyanogenmod. Any help would be appreciated! Thanks!

[Verizon LG G3] tu3218:
Anyone know of a good way to do this? Basically I only want knock code on when I'm not connected to my home wifi or in car bluetooth. I've seen an called Skip Lock but reviews aren't that great.
[Verizon LG G3] firewhank:
Use Tasker, you can program it to do everything
[Verizon LG G3] allan1313:
I used delayed lock from the play store. I use it for known WiFi abd trusted Bluetooth. Works awesome.

[Verizon LG G3] tu3218:
That looks awesome! However, it seems I can't use knock code with it which is what I was hoping to use.
[Verizon LG G3] allan1313:
Oh I see. I think you can only use pin or pattern with it. I don't know of one that can use lock code.

I'm using Automateit. Works perfect and I can use knock code.

Huawei MediaPad 10 Link is less known tablet with good specs. General specs are:

Huawei HiSilicon K3V2 1.2 GHz quad-core processor based on ARM Cortex-A9

1 GB RAM

1280x800 (1280x752 actual res.)

160 DPi

8 GB Internal Storage

S10-201U (WiFi+3G Only)

Vivante GC4000 GPU (Huawei said its "gaming" tablet i think not its lags and gives max 20 fps on basic games)

Android specs;

Version: 4.1.2 Jelly Bean API Level 18

6000 mAh battery.

Low to mid end range tablet but have no custom roms or recovery. Stock firmware is total bulls***. Lags way too much and makes tablet sometimes unusable. I wonder why anyone not intrested in with this tablet i see many people waits for it. Is there any developer works on this? If no sadly i have to sell this tablet because i cannot use due to over lagging software. (Full stock only rooted and bloatware removed without any tweaks)

IMPORTANT!

There is no Q&A forum so i have to post it here sorry for it!

[Shield Tablet Q&A, Help & Troubleshooting] android_nashville:
Hi Team,

I am on about week three with my shield tab and it has been up and down. The up is that gaming is AMAZING. I don't even have a controller yet, on order from Newegg where they are in stock.

Now for the bad. I am on my second tablet. The first one I got from Newegg and had problems almost out of the gate. The best way to explain it is problems going to sleep and waking. I would push the power button and nothing would happen, push it again and it would freeze. When trying to wake up it just wouldn't do anything at all. I would reboot and it would work fine for a while. Talked to Nvidia customer service and after uploading videos to youtube and such they filed an RMA and sent me a brand new tablet in about two days!!

Now having the same problem to a MUCH less degree. After gaming, doing searches, browsing it has trouble going to sleep and waking. Once an app starts, no problem at all. No lag at all with gaming. JUST going to sleep and waking from sleep. Whenever there is a problem I restart the tablet and it moves smooth as silk for several hours until it does it again. I've tried closing apps all the time, doing RAM optimization with third party apps, nada. Seems to happen when I quickly go from running an app to sleep then awake again. I would blame in myself but I did the same exact actions with my Nexus 7 with no issues at all.

Help!
[Shield Tablet Q&A, Help & Troubleshooting] Gnurou:
You don't happen to have enabled ART instead of Dalvik in the Developer Settings, do you? I remember having similar issues when I did.
[Shield Tablet Q&A, Help & Troubleshooting] android_nashville:
No I don't but that is a great point. I switched over to ART to see if it would help and it got worse + a bunch of apps wouldn't work.

Thinking a very light custom rom would help but not sure I want to void my warranty by unlocking bootloader.
[Shield Tablet Q&A, Help & Troubleshooting] Gnurou:
After I reverted to Dalvik I found the tablet to be very stable, so I am out of clues here. Power saving settings maybe?
[Shield Tablet Q&A, Help & Troubleshooting] android_nashville:
I am running on max performance and noted its way better than battery optimized. I will keep trucking, its not that bad. Like I said, there is no app lag whatsoever, just sleep/wake issues. I just don't like rebooting 5x per day... even considered changing over to a Galaxy Tab S but am holding out.
