0% battery on SE Neo

Hi guys,

I had the same problem with my SE NEO. I did the phone back to the store for repair and after 5 weeks I got the following statement:

"Dear customer, Your device isn't repairable, please come back to the shop where we give you full refund so you can choose another phone. Thanks for your patience and understanding"

This means that SE also has problems fixing the issue. So for all the guys who want a new phone, go back to the shop and claim your warranty :-) but make sure you flash back the ! original ! bootloader

and

rom before you head back :-).

If you ask me, I find this a really good service! Thumbs up :-D
[Xperia Arc Android Development] steryman:
lol um... actually the single fixes are hardware... so changing the fuel gauge, the MB or the phone will fix this... that would be cool because when I bought my Arc it cost more than Arc S in present xD So maybe they'll refund me and I'll get Arc S xD
[Xperia Arc Android Development] grizzlyspid86:
Well lucky you! Mine got back from service center with the same phone, same motherboard (same imei number). I think they just replace mine with the new fuel gauge hardware. Anyway I'm happy now that my phone's alive! :D
[Xperia Arc Android Development] sebasgl1:
ok, so the main problem for our comunnity trying to repair this, is that we cannot communicate with the fuel cauge, but... SE maybe can. i'm right? in my contry a problem like this is meaning of change phone by warranty but i dont want that... and i lose my charger so... that is another problem with the warranty... if i wait, maybe in 2.3.5 or ICS sony would get this prooblem fixed?¿
[Xperia Arc Android Development] pandaball:
That is not possible, it is already established that this is a hardware problem and it cannot be fixed via software, the only software measure possible is a stopgap measure to fake the readings of the fuel gauge if you have this 0% battery problem.
[Xperia Arc Android Development] sebasgl1:
aahhhhh ok thanks... warranty here i come
[Xperia Arc Android Development] JMSpurs:
The problem is that the firmware on the fuel gauge chip is corrupt. Therefore I was wondering if there was a way to see if the i2c bus could see an unknown device and if so maybe the chip could be recoverable. Any suggestions?
[Xperia Arc Android Development] galati:
I solved the problem of 0 battery sending my phone to SE service and there change my mb . All ok. But after 2 weeks after i have again my phone in my hands surprise : my fu....... SE ARC is dead again . I see two self rebooting and after half hour my beautifoul phone no charge , no respond , no nothing. So monday again to service.
[Xperia Arc Android Development] sebasgl1:
damn it... my carrier dind't what to repair my phone... ¬¬ this looks like i need to unlock the Bootloader
[Xperia Arc Android Development] cesar7:
Replacing the fuel gauge? fix the problem?
[Xperia Arc Android Development] sebasgl1:
yeah, because the new chip would'nt have a corrupted firmware
[Xperia Arc Android Development] cesar7:
Ok, thx. Anyone know any tutorial to replace the fuel gauge. I want try this.
[Xperia Arc Android Development] JMSpurs:
Well if you search around on these forums you'll find people who've done it. Though it will be difficult as I believe it's a 15 pin connection between the chip and mobo. So it'll take a lot of time and desoldering, if you attempt, I wish you good luck.
[Xperia Arc Android Development] cesar7:
Yes, the only way is do this with a hot air solder. My warranty is off, need to try...
[Xperia Arc Android Development] JMSpurs:
Can you post your results please for the benefits of others, thanks.
[Xperia Arc Android Development] fistanfilan:
I had a loop issue with a red light. I have relocked the Bootloader, and tried to install the latest update by SEUS. Now everything is ok.
[Xperia Arc Android Development] Ninoh-FOX:
WHATS!!!!?
[Xperia Arc Android Development] PAVNEET101:
will replacing battery will fix this issue ??? as my phone is under warrant and i called SE they told me that they will send in a new battery, please let me now

Thanks
[Xperia Arc Android Development] iridaki:
No, this doesn't have to do with the battery, it has to do with how the phone "reads" the battery percentage. You need to have your motherboard replaced.
[Xperia Arc Android Development] PAVNEET101:
Ok thanks for replying, I applied the patch to fix it and now is working with out the charger but always show 85% why is that and grow can I fix it ???

Thank you

Download the last bazoocaze apk available on this page :

This apk will estimate the power consumption and return a estimated purcentage of the current battery capacity.

But if your phone is under guarantee, try to replace it.

Replace your phone if you have warranty. If you dont', then unlock the bootloader and start using the fix on link above.
[Xperia Arc Android Development] hellocng:
Has anyone used the *#*#7378423#*#* in phone dialer to access the service tests/info built in? It gives a battery test and battery health info as well as the fuel gauge firmware. Can we compare the fuel gauge firmware? If something in the update/downgrade can access the firmware to corrupt it, perhaps there is a way to access the firmware and fix it. Although there is a fix via software, it requires an unlocked bootloader. Secondly, this makes it largely inconvenient in changing ROMs. I know this issue has been studied for a few months but may be we can brainstorm some other angles we might not have looked at?
[Xperia Arc Android Development] Bazoocaze:
All brainstorm is worthy!

We allready tried to access the failed chip to rewrite it's firmware (first thing done), but the firmware curruption did it inacessible for firmware rewrite. It's not responding on the I2C bus, that is the only way you can flash a new firmware, so we stablished that this is an unrecoverable hardware failure, unless the chip gets back to responds on the I2C communication. Think of it as a black box: you can only interact with it via I2C bus, and if you can't communicate via I2C, the chip is virtualy dead.
[Xperia Arc Android Development] bolochan:
Crap!!!! After numerous flashes with flashtool and SEUS, my phone now has a permenant 0% battery issue... regardless of firmware. No!!! I didn't think flashing a firmware would do this!
[Xperia Arc Android Development] prance666:
please check this too: (arc s)
[Xperia Arc Android Development] Jinx13:
As already stated it seems the issue arised when a user had a gap between firmwares

IE. 2.2 to 2.4

or 2.4 to 2.2

Not 2.2 to 2.3 to 2.4

or 2.4 to 2.3 to 2.2

Etc etc etc

So are you sure that in your "numerous flashes with flashtool and SEUS" You did not jump firmwares like that?

Could someone please fill me in with whats up with mine or check if there is anything unusual according to the 0% battery problem? (Arc)

Im using Arconium 5.6 with patched doomkernel.
[Xperia Arc Android Development] Bazoocaze:
This is not the official thread to ask for support. You must ask on the correct thread, so me and Steryman can give support about the patch and the custom kernel version.

About your log file, it shows to be all normal: you have the battery issue, and the patch show a charging procedure from 78 to 96%.

Has anybody tried contacting with sony erisson yet?
[Xperia Arc Android Development] :
I have but still no reply. I believe others in a different thread have also.
[Xperia Arc Android Development] Xperianeo:
i think if we can clear everything in the ROM then reflash with another rom. it will be ok.
[Xperia Arc Android Development] Flo95:
I think SE won't answer the people with the problem.

They did something that's not wanted by se...

But I wish the people who have this problem good luck with fixing it.
[Xperia Arc Android Development] tonyb15re:
All good until the battery runs out because its not been charging. Then what do you do?
[Xperia Arc Android Development] :
Do anybody know all partitions for arc?? Cause in fastboot we can erase specific partitions, i think if i will erase some of partitions and then re install them it defiantly should help!

I erased partitions system and boot, re installed, but still 0%..........
[Xperia Arc Android Development] :
Tried that on 2.3.4 unrooted and it proceeded to shut down immediately after removing the usb cable.
[Xperia Arc Android Development] hakhater:
I think there is an option in recovery to wipe battery status or something ... did you try that ???

I hope you guys find a solution for your phones
[Xperia Arc Android Development] :
Yes there is option to wipe battery stats and yes i tried it, didn't help.
[Xperia Arc Android Development] jeRrRKKKK:
tried that on 2.3.2, the phone says pls connect charger, stuck at that window

able to turn off the screen and when turned on again the device is in lockscreen but it says no sim card installed

after turning to potrait mode and landscape mode again i'm now able to access the menus, but the phone is extremely slow and it still says no sim card connected

i guess if somebody can write a script to restart several services, perhaps this problem might be partially solved
[Xperia Arc Android Development] :
Just adding that for me it actually hanged when trying to shut down. Had to remove the battery for it to turn off. I also noticed User Agent Provider or whatever kept on restarting itself after a force close.

Though even though we may find a temporary solution, it would be nice to find out how to permanently fix this.
[Xperia Arc Android Development] Elessar76:
My last post wasn't a solution. Of course that closing services the phone doesn't works properly. But maybe it's a clue of what service is corrupted.
[Xperia Arc Android Development] Jinx13:

[Xperia Arc Android Development] icet925:

[Xperia Arc Android Development] visarya:

[Xperia Arc Android Development] :
I've attempted it from 2.3.2 because root is required but have run into errors. I posted in the other forum detailing it.

Anyone on 2.3.4 rooted want to try?
[Xperia Arc Android Development] abhisheak.bansal:
can u tell me how this 0% battery problem is caused?what are its ill effects?
[Xperia Arc Android Development] :
The 0% problem is cause from downgrading from 2.3.4 to .181 UK. And its ill effects are the battery being shown as 0% so the phone does not work without the charger and cannot do OTA upgrade.
[Xperia Arc Android Development] abhisheak.bansal:
so if i downgrade from

.283

WORLD GENERIC to

.368

WORLD GENERIC then this problem will not be caused?
[Xperia Arc Android Development] Elessar76:
Just a note... I downgraded to .181 german in my Neo and had same issue. So not exclusive .181 UK problem.
[Xperia Arc Android Development] taaviu:
You are right!
[Xperia Arc Android Development] tonyb15re:
I think its more than that, I think its a combination of the downgrade and gingerbreak.. I didnt have the issue until I ran GB..

Note you can upgrade again using the Desktop Suite, BUT that doesnt fix it..

I used Flashtool to put my device back to the correct ROM and sent it off to the service centre..
[Xperia Arc Android Development] icet925:
Some people have the issue with out using gingerbreak.

The service center would probably replace your mobo as usual.

Apparently, it could be a driver function error.
[Xperia Arc Android Development] tonyb15re:
It clearly is a Driver or missing component, Im suprised one of the devs with a working intimate knowledge of the ROM can't assist by doing a diff between a broken install/extracted rom and a known working install/extracted rom..

What's frustrating is that even a re-flash back to standard doesnt fix it so its something that a simple FLASH doesnt sort out, would be useful if we could do something like a complete format of the system then flash but I guess there are areas that we shouldnt be touching

[Xperia Arc Android Development] FiDra:
Hi guys,

These are some information I think it will help:

- I flashed this firmware: http://www.mediafire.com/?68r93ddskychhoa

(This is a Docomo firmware which has been modified, so you can flash it to an un-Docomo Arc)

- Flashed successfully. Info:

+++ Android: 2.3.2

+++ PIN: 1%

(PIN shown 1% but you can use it as normal. The phone does not shut down any more.)

+++ Charging: Yes, as normal. But always said 1%.

- Then, I flashed the Custom KERNEL of DoomLord and Blend:

+++ PIN: 0% --> Phone shut down.

- Then, I re-flashed the Stock KERNEL from Docomo's firmware:

+++ PIN: 1% --> Phone DOES NOT shut down. And you can use it as normal.

----- Another tests -----

- Flashed Docomo - then UK firmware build 181 --> No help. PIN 0%, phone shut down.

- Flashed Docomo - then Global 2.3.4 build 283 --> PIN 0%, phone shut down.

- Flashed Docomo - then UK firmware build 181 - then Global 2.3.4 build 283 --> PIN 0%, phone shut down.

- Flashed Docomo - Installed custom ROM Blend@ARC --> PIN 0%, phone shut down.

That's all what I've tested on my Arc.

Through all my tests, I think this issue is some kind related to the kernel of the 2.3.4.

Now I'm using the modified Docomo's firmware and the phone runs fine (PIN said 1%).

This is a temporary solution until the permanent solution is out.

Hope this help!
[Xperia Arc Android Development] datagubben:
Nice finding.
[Xperia Arc Android Development] jeRrRKKKK:
have you tried removing the battery after flashing the docomo firmware?

removing the battery is supposed to solve the 1% issue

could this also be because of a l15i or l15a issue?

perhaps flashing a l15a firmware on a l15i caused the problem in the 1st place?
[Xperia Arc Android Development] slowadi:
Nice job:) ... now the question is "how safe is to run the arc under these ?!"...:confused:
[Xperia Arc Android Development] shahzaib.khan:
same prob here :S its soo annoyying :@
[Xperia Arc Android Development] visarya:
good news , it looks like it is a kernal related issue , i created a new ftf using kernel from docomo ftf and it can be applied as a patch after installing any 2.3.2 firmware. however you will be stuck with 1% battery issue.

this is just a temp fix till we get a real fix for the issue
[Xperia Arc Android Development] FiDra:
No, I did not dude :).

But I think that will not solve the problem in this case.

Thanks visarya! I'm flashing the 2.3.2 UK now. The performance of the Docomo firmware is too slow and laggy :)
[Xperia Arc Android Development] icet925:
Nice finding.

I've installed this patch on my xperia arc and working.

i dont have docomo jp 181 firmware from neo , i would need access to docomo neo firmware first. FiDra got hold of docomo firmware for arc , please ping him if he can get hold of same firmware for neo.

guys please thank FiDra as he was the one who identified that docomo firmware solves the issue . i just extracted the kernel sin from the ftf and created a patch
[Xperia Arc Android Development] morenoro:
Thank you FiDra for that discover and thank you Visarya for the patch. This is a good start to fix our Arcs. Thank you again.
[Xperia Arc Android Development] FiDra:
You are all welcome, guys!

I've also searched around and found that firmware in a Vietnamese forum (http://www.tinhte.vn/thay-doi-nang-...oot-loader-cho-xperia-arc-854709/index48.html).

Because that is the Vietnamese forum (I'm Vietnamese), so if there is anything new, I will update here a.s.a.p.

Hope that this issue will be fixed soon :)

By the way, morenoro, can you post a reply to the setool forum to tell the_laser that the re-compiled of the kernel that included his patch did not work. I flashed the kernel but the phone did not start:

-- I pressed power button, it's just vibrated then nothing happens. The Sony Ericsson logo was not shown.

-- I pressed the power button again, no vibration, no logo, nothing else.

Thanks!
[Xperia Arc Android Development] morenoro:
Send it to the_laser.

By the way, we must to think the thread in setool began with NEO problem. Here we are talking about ARC. Maybe we are trying to install kernel for Neo with our Arc.
[Xperia Arc Android Development] FiDra:
Oops, I forgot about that :D

Oh man, that's why my phone did not start after I've flashed that kernel :D

(The LED is blinking like a Blackberry :D)
[Xperia Arc Android Development] datagubben:
Just some brainstorming ideas:

Could it have something to do with different flashtool versions?

Cause when I use the .184 method it works everytime. I am using Sony Ericsson X10 Flasher, version 0.2.9.1

Maybe it helps? :)
[Xperia Arc Android Development] uyo_kun:
well some weird thing happen. After I flash .146 with battery patch, I tried OTA, but it say my phone got latest version... weird isn't it? :D
[Xperia Arc Android Development] Ghost_kh_07:
Yes this rom no new firmware update ota. But with 1% battery you can not update over ota
[Xperia Arc Android Development] uyo_kun:
But it says that your phone version is up to date. If you got low battery, it says that your battery is low. My phone can OTA but say up to date.
[Xperia Arc Android Development] morenoro:
Yes, but phone won´t let you update if you have low battery (that´s for security), you know if the update interrupt, you´ll have a nice brick in your pocket.

I want ask a question. Is .184 battery if you patch update with PC Companion will still got 1% battery?
[Xperia Arc Android Development] FiDra:
If you flash a 184 with PC Companion, the you will need to flash the patch with flashtool. Otherwise, the battery will shown 0% and phone keeps shutting down.
[Xperia Arc Android Development] uyo_kun:
its sad then... I want the .368 with battery patch...
[Xperia Arc Android Development] morenoro:
So, is there any way to get 2.3.4 version with patch battery or at least 2.3.3 version with themes, xloud, zoom, etc?

Any way to get root with the patched versions?
[Xperia Arc Android Development] shahzaib.khan:
Any one monitering on this issue?...
[Xperia Arc Android Development] hellocng:
The patch has stopped working for me as I flashed a few more ROMs to test. So my advice, if you need to use your device daily, dont mess with ROMs.
[Xperia Arc Android Development] morenoro:
Ok. We have been desperately looking for a solution for our phones. I think now we are not in the right way. I don´t know how to compilate firmwares or modify kernel; but Doomlord here, the_laser from setool and others can help us to do it.

First, we know it´s a software problem cause some firmwares and patch can give us a temporary solution, so, let´s go to try to solve with a permanent solution.

We must to know that Neo and Arc have the same issue, but if we mix kernel from Neo with Arc´s software probably we won´t find any solution.

We must compile our ideas (ones for Neo and ones for Arc) and try to follow separated ways to find the permanent solution for both phones.

Thank you to everybody, to every developer here and there for try to solve our battery´s problem.
