Wait a second I think it's still not Hardware issue as the phone still can detect somehow the battery %.. it really gone 0%, it announced me of low battery and shut down. Now if I try to turn on my phone it's not powering up, and the led is blinking red 3 times and quicker, announcing it's empty. I'm charging now the battery.

Later Edit 1: It seems I need to use the charger, because the PC doesn't recognize the phone... strange...

Later Edit 2: Nope... still no problem even after charging a little. Oh and, if you flash the battery patch (1% patch) on a WORKING phone.. I mean no problems with the fuel gauge... will it show the current percent of the battery or 1%?
[Xperia Arc Android Development] heidality:
i think your words have true...but how we can resolve this problem

yes battery normal working after patch,so hardware is not being.

we have a logs with and without patch,think we may resolve it?
[Xperia Arc Android Development] morenoro:
Maybe now there is a lot of hundred phones in SE services around the world. So, if they are not too silly, they have knowledge about this problem. I dont think they want to spend too many money if they could make a patch software to fix this. If they are changing the motherboard or just the fuelgauge chip is cause there is no software solution now. So...,we can try solutions, but I really think we'll not find anything. So we must to try to find the best solution ( patch over the last firmware) or go with warranty to SE.
[Xperia Arc Android Development] kpmkat:
Welcome in 0% battery club ... :/

Hope someone will find a solution soon.
[Xperia Arc Android Development] silentxnl:
Small chance, if you have warranty, bring it to service asap.
[Xperia Arc Android Development] kpmkat:
Did it this morning...

So what is causing problem - downgrade or Gingerbreak ?

I've done downgrade to root my phone and as far as I can remember everything was ok, until I used Gingerbreak...
[Xperia Arc Android Development] jojora:
which was the first version of firmware the arc?
[Xperia Arc Android Development] kpmkat:
Newest firmware flashed with SE Tool - downgraded to 181 and rooted, then again flashed through SE Update on pc, downgraded, rooted with Gingerbreak and booom 0%

I think SE could put something in new firmware - you can not root the phone or even download the newest through OTA so even if you manage to root it on 1% fix you are not able to get the newest firmware with keeping your phone rooted.
[Xperia Arc Android Development] centi50:
Does this 0% problem Occurs if downgrading from 2.3.4 to 2.3.3 or is it only to 2.3.2
[Xperia Arc Android Development] datagubben:
You can, but with .184 first.
[Xperia Arc Android Development] centi50:
Thank you datagubben so you can not encounter this prob if you go from 2.3.4-.184-.181-root then OTA 2.3.4
[Xperia Arc Android Development] prabuul:
only from 2.3.4 to 2.3.2 and gingerbreak may be.....

i have .184 for the first time it went well and OTA did to 2.3.4 but for ome reason i did the 2.3.2 with .181 then gingerbreak since then the light gone to red.
[Xperia Arc Android Development] heidality:
end of the story 0% battery everyone must go to Service:D:D:D
[Xperia Arc Android Development] taaviu:
Crazy!!!
[Xperia Arc Android Development] steryman:
Nope. I have a feeling it's a software issue yet... it's normal to fix it by replacing the hardware, it's like you are virusing the Windows and you repair it by replacing the HDD with another one having clean Windows... same thing here, I still think it's software issue and I won't give up.

dear friends yesterday i collected logs working arc and ours not working and working with patch

we have a problem with bq27520 and i2c files.

i other arc and neo i cant see problem with bq27520 how we can full delete phone memory ?i think if we delete all files in phone memory we may try write firmware again..maybe when we write firmware again and again the files power_supply dont written and not changes.how i do full reboot i want empty arc..

i hope you my friends understand me.

:eek: In the playing around trying to root my one week old Arc S (LT18i) without unlocking the boot loader... I've managed to get the 0% battery also :(

Time to take back to the store for an exchange.
[Xperia Arc Android Development] constantinexx:
they sent me OFF ..they gave me a sheet with "THIS PHONE IS NOT SUPPORTED"

cause as they said the 2.3.4 is not for the ARC yet iwas shocked

and gave me alog with all my tries to the flash the phone i think they did this intentionally to lock the "unsupported phones" following APPLE's steps to prevent the downgrade punishing the manipulaters :) :)

so as some one said earlier that we dont nett to change the HDD we need TO format the windows "if YOU CAN SAY"

AGAIN I INSIST THAT IS A SOFTWARE ISSUE I THINK..:mad::(
[Xperia Arc Android Development] tandem2:
0% again

the same for me. 0% error...I have to find my old Windows Mobile XDA...
[Xperia Arc Android Development] steryman:
But remember, we don't need to fully format the phone's memory, otherwise we'll lose also the primary functions like detecting the power up button to start the phone and we'll have a dead phone 4ever, because it will lose even the flash mode function.
[Xperia Arc Android Development] infernose:
i downgraded to 2.3.2, rooted with gingerbreak, had the zero battery issue, then powered down and took out the battery for a few minutes. when i put battery back on and powered back up, battery was back.

[Xperia Arc Android Development] plopingo:
Are you really sure is a hardware issue, i've fixed that with a simple flash ...

Don't break your phone :/
[Xperia Arc Android Development] shahzaib.khan:
its not the hardware issue im sure..hardware change is just a another solution because no one detect the solution through software.every body knows its possible to solve this issue throug softwares but nobody can create a solution for this even SE dosnt have the solution throug software...
[Xperia Arc Android Development] steryman:
If you said you didn't downgraded, and you had directly the 1% battery issue, all you had to do is to remove your battery for 30 seconds.
[Xperia Arc Android Development] plopingo:
I've tried this method but not working on my phone

But all working good now so .... :)
[Xperia Arc Android Development] ToMmY_hun:
Its not a hardware problem, but the CPU cant communicate with the FG IC. I think, the replacing is the only way to solve this problem. By the way: How did you flash it?

[Xperia Arc Android Development] yunle:
A developer from SE China has started looking into this problem.

He has posted two threads on a Chinese android device forum in Chinese.

Here are the links to the threads in case anyone here is interested and able to read Chinese.

http://sebbs.it168.com/thread-340325906-1-1.html

http://sebbs.it168.com/thread-340325949-1-1.html

He claimed that he has figured out what happened. He is trying to find a solution right now.

From what I can understand from his posts, the problem he found was similar to what Bin4ry said.

Wish him good luck:)
[Xperia Arc Android Development] :
If you already have .181 ftf just use the previously posted 1% battery patch. Much smaller download.
[Xperia Arc Android Development] damogran:
Thanks for letting us know! Would you be so kind and inform us about further topic updates?

Good to hear that we have another (small) hope. :)

Thanks again!
[Xperia Arc Android Development] uyo_kun:
If he can solve this problem, I think I'll give him a beer for his work:D
[Xperia Arc Android Development] Bin4ry:
Quick question, has anyone of you tried to fake some battery status via properties ?

Example:

# setprop status.battery.level 90

and after that see if the status is still there ?

Will the phone work, but always stay at 1% ..?

Exactly, stays at 1% ...
[Xperia Arc Android Development] heidality:
No.You can't update to higher firmware.always 181 or 184
[Xperia Arc Android Development] Bazoocaze:
Interesting. Maybe you can try this (extracted from /init.goldfish.rc):

# setprop status.battery.state Slow

# setprop status.battery.level 5

# setprop status.battery.level_raw 50

# setprop status.battery.level_scale 9

Play with the values to see if the bat level increase.

Could you be more specific? what ROM did you use? (link?)

I've allready tryed flashing LT15i_3.0.A.2.181_Global_Customized , which I assume is the "old" one, and it apparently didn't change the situtuation for me, still 0% battery

Here are some updates by the end of today.

1) It is able to set the battery level to stick at 100% (similar to the 1% patch I think). Trying other possible solutions.

2) The process of downgrading and rooting damages the fuel gauge chip (as we already known).

3) He thinks that damaging the fuel gauge chip by using flashtool and gingerbreak has actually violated the warranty agreement.

4) Tying to develop a temporary kernal.sin to solve this problem.

5) It seemed like this is a very complicated problem. He will discuss this problem with his Sweden colleagues tonight (Beijing Time)

6) A report regarding to this issue has been filed.

7) He is not able to solve this problem by himself alone. And he is trying to get help from other departments ...

Alright, so I think if you still have your warranty and you are waiting for solution from XDA, I suggest you to send your phone to service now, before SE might claim you have voided the warranty.

The link to his thread is here.

My phone got bugged actually when I used gingerbreak, because when I downgraded I also rebooted before rooting, and it was still working fine, then after the root, all screwed up
[Xperia Arc Android Development] galati:
False . Like i said before , i flashed and reflashed my arc and this bug never appears.just after root the device with gingerbreak this problem apears for the first time , and i solved getting out the battery , after this i reflash the device again with 181 ,cause i update via seus and lost root and again no problem after reflash ,the battery at 100 % ,but and i make again the root with gingerbreak and the 0% appears again the difference is this time the problem not dessapiers with a simple putting out a battery.Sorry for my bad english

He found a solution that use software to report battery level instead of fuel guage chip.

A rumor says he is the director of testing, not a developer...

Very good news, thanks yunle

even thought I already received my phone ( they replaced the mobo on warranty )... but its very good move for those who could not get the warranty...

but I'm wondering about ICS root also :D
[Xperia Arc Android Development] silentxnl:
Should have really done it with SEUS.

Cause SEUS also checks if you still have warranty on your phone.

If yours didnt have warranty it will be registered, and next time when u fix warranty it wont be accepted.

I have an update from my phone today.

They wont replace the mobo, they are sending a brand new phone.
[Xperia Arc Android Development] yunle:
GREAT NEWS!!!

Official solution to 0% battery problem will be released along with next major upgrade, probably the android 4.0 firmware. There might be another firmware before 4.0.

The developer (or director of testing, whoever he is), cannot release the official patch himself. However, thanks to the open source of android, he can hand over this work unofficially to a third party dev to develop an unofficial patch. This patch is gonna arrive probably on this weekend. So please be patient.

The patch is gonna be based on 4.0.1.A.0.283, probably 4.0.2.xxx as well.

This patch is unofficial, and volunteer work, so he will not be responsible to any consequence. Use it at your own risk!

The patch is unofficial. There is no official patch. SE will not release any patch for it. The next firmware will fix this problem. You can use the unofficial patch to fix you phone, or you can wait for the next upgrade if you dont trust the unofficialpatch.
