[Xperia Arc General] nayanasri:
Anyway thanks to you guys I am happily using my arc with this workaround for few months.

I am thinking about replacing the fuel gauge chip by an experienced tech (a friend of mine).

However in some forums fuel gauge chip is stated as : Maxim MAX17040

In this thread : Texas Instruments bq27520

Do both are same ?

or is there are several clones out there from different chip manufactures ?

The attached picture is correct right ?

Please enlighten us :)

Thanks in advance.
[Xperia Arc General] :
Hi Nayanasri, Maxim max17040 is still fuel gauge chip, but "fuel gauge" is just a functions name and yes 'maxim max 17040' is chip from entirely other manufacturer, so we can't use it on arc.
[Xperia Arc General] nayanasri:
Ah, right.

Sorry, I was not clear in my previous post. I was talking about the xperia arc's fuel gauge too.

In this > theelectronicfreak.blogspot.com/2011/08/sony-ericsson-xperia-arc-teardown-and.html < web site, it is said xperia arc's fuel gauge chip is "Maxim MAX17040" . Also I've seen it in some other forums too. O.o

That's why I confused :confused:

Thank you for the reply.

P.S. The chip marked in the attached picture is correct, right ? (# 965)
[Xperia Arc General] :
:-D You just confused me... I'll open my arc and I will take a look on that chip with magnifier glass to try find some product code

---------- Post added at 08:36 PM ---------- Previous post was at 08:07 PM ----------

I checked that chip (from above picture) and yes it is fuel gauge, on it is Serial Number some other number and TI initials. I could not read all serial nr cause my glass is not that good, I think for something like that microscope should be used.

BTW I think that it is UNREAL to solder that kind a chip, my mate from university looked at it and told that it is impossible to do something like that!
[Xperia Arc General] nayanasri:
Oops ... :D

That's a good idea. I've seen some one posted earlier, his arc's fuel gauge chip imprint as "TI 13A0VEI, SN 1002036".

Anyway take ya time and post here your findings. No rush :)

Cheers !!!

---------- Post added at 01:34 AM ---------- Previous post was at 01:16 AM ----------

Just see this update. :)

Thank you very much. I'll ask my technician friend and post here what he said. He is in the mobile phone repairing field more than 15 years by the way. But who knows :rolleyes: The chip has 15 pins and around 2mm x 2mm sized. Very delicate.

Since recently there's an Official ICS ROM for ARC S , has anyone had tried to use the ICS beta kernel on the official ICS ROM on a Xperia Arc? or is there a kernel specifically for the official ICS ROM?

Does anyone know if it can work? I will try to use it on my Xperia Arc tomorrow and see what happens :D , but i wanted to ask first if anyone already did that and what was the result.

Excuse me for my english.

I tried the ICS beta for Arc S on my Arc, and it ran smoothly.

Even PCCompanion detected it as an S!!!

So go on and try for yourself :D

[Xperia Arc General] Bazoocaze:
Guys, if your are using the 100% patch (v3), please flash as fast as possible the v3.1 (85%), because I think the 100% version doesnt allow the charger to work correctly when android is on. Leave the phone charging for a while shuted off, and then try to flash the new version.
[Xperia Arc General] Bazoocaze:
Please, what version of patch are you using?

-v3 100%

-v3.1 85%
[Xperia Arc General] shahzaib.khan:
dude u r awesum.....thnx alot for the patch but im still waiting so desperetly for the official solution
[Xperia Arc General] srebar:
currently using v3.0, as of now i cannot patch it with v3.1 (not enough skills).

and for the other question, no i haven't fixed the 0% problem so far, just managed to partly fix my ARC when it was not powering on after the patch.

sry if i missled you, i'm still looking for a solution and thinking of it 24/7. Even tried a trick i used on my PSP when i got the same problem with 0% battery (to short circuit it) but it didn't work...

EDIT: Just saw that you (Bazoocaze) posted the v3.1 patch, i'll patch it now and write here ASAP.

tnx for everything

Flashed with v3.1 so far powers up with no problem and shows 85% charged, i'll write again when my batterie is drained to let you know if the problem with the 100% patch is appearing in this version.
[Xperia Arc General] fcb13:
Anyone tried flashing one of the MIUI roms? Since they have 2.3.7 firmware maybe it will fix this issue on it? I don't know im simply wondering
[Xperia Arc General] paiwhonan:
For everyone who has no idea .I think you can do it with my step

1.you must unlockbootloader (but destroy your warranty)

http://www.theandroidsoul.com/how-to-unlock-bootloader-xperia-arc-play-neo-pro/

then you should know how to fast boot

2.download the lastest firmware

Neo http://xdaforums.com/showthread.php?t=1258723

Arc: Sorry I used Neo and I do not sure the lastest version of Arc

3.flash the lastest firmware with flashtool

http://xdaforums.com/showthread.php?t=920746

4.fast boot with version 3.1

http://xdaforums.com/showthread.php?t=1312398

if you downloaded you must rename this file

For Arc boot.img.arc to boot.img

For Neo boot.img.neo to boot.img

And fast boot with command “fastboot flash boot boot.img”

Thank you Bazoocaze you are the great:)
[Xperia Arc General] masray:
Dear Friend：

Really appreciate your modded kernel，it's amazing！！！ Dozens of our

people are using their ARC/NEOs again with your solution，we finally get rid of the power cable.

MANY MANY THANKS,MAN!!!

from CHINA
[Xperia Arc General] aifish:
Thank you for your help. In China, I know people, about 300 people(NEO&ARC), by the way you have to temporarily solve the problem of 0% battery. I thank you on their behalf. We look forward to v4 version can help solve the problem. Thank you very much.
[Xperia Arc General] lastword112:
There will never be any official solution,you void your warranty by unlocking the bootloader, if your bootloader is still locked, i suggest you to flash the official firmware of your region and send it for replacement to SE, because as stated by the OP this is a hardware failure.

Btw OP awesome job :)
[Xperia Arc General] itachi naruto:
oh my god 3 hours running youtube , 2 hours running game , 1 hours running browser no battery , I asked when the battery
[Xperia Arc General] peacekeeper38:
lucky all of you guys who can recuperate the arc from the 100% patch issue and put the 85% patch. in my case i can not do it.

i left my cell connected to the computer via usb cable the whole afternoon, i came back at night and try to do as soon as possible how it says in one of the previous post the flashing and the booting of the image but still the same didn't let me do it, the cell keeps turning on and after 2 or 3 minutes shut down, really don't know what else to do, i think is because this cycle "on and off " that battery don't receive to much charge well is what i think
[Xperia Arc General] JMSpurs:
OK guys, later I'm going to try and find out more info about the bq27520 chip to try and solve this problem once and for all.

Got to wait until 9:00 then I'll post my results.
[Xperia Arc General] SoraHaru:
First,thank to Bazoocaze for revive our Arc ^^......!!!!!! Hey peacekeeper38 ,I'm had stuck with this problem like you all night.You no need to charge so long. Let try my method , if you connect the phone in fastboot mode and show just Red LED blinking. You must pull the USB cable out and connect it again until it reach into the fastboot mode.I don't know the frequency that I try to connect but it's work for me.Just try that ^^......!!
[Xperia Arc General] peacekeeper38:
OOOOOHHHHH sounds good the method SoraHaru i am going to try just right now actually i put the phone to charge about 20 minutes ago but right now i will try hopefully this help me thnks a lot fr the tip:o

I hope you can post too JMSpurs

SoraHaru thank you very much thank u a lot friend u rescue my day, right now here in my country its 3:50 am and finally i could solve the issue thanks to u very appreciated ur help :D:D:D:D:D:rolleyes:
[Xperia Arc General] Bazoocaze:
Good. You can start here:

BQ27520 datasheets from TI:

http://www.ti.com/product/bq27520-g2

Xperia Android Kernel source code from SE (include driver for bq27520):

http://developer.sonyericsson.com/wportal/devworld/search-downloads/android?cc=gb&lc=en

The driver for fuel gauge is /kernel/drivers/power/bq27520_battery.c

Good luck.
[Xperia Arc General] JMSpurs:
Well i saw on another thread where someone had replaced the chip and there phone was working fine. So I'm going to try and come up with a way to do some kind of a hard reset on the chip, which is difficult as my Neo is fine and i don't really want to lose warranty or break it.

http://www.ti.com/lit/an/slua453a/slua453a.pdf

mentions a program, if I can find the program might be able to install new firmware for chip.

Someone with problem try messing around with this program http://www.ti.com/litv/zip/sluc252

Can someone post their results because I would do it but I don't want to break my Neo again.
[Xperia Arc General] Bazoocaze:
bq27520 stopped communicating on i2c bus. You cant "hard reset" (allready tried), nor install new firmware (needs i2c communication).
[Xperia Arc General] JMSpurs:
could you try and reset the i2c bus

Also could removing it from device and then reattaching reset the bq27520, it would if it had memory similar to ram.
[Xperia Arc General] Madfysh:
More detailed/complete than in first post? Are you joking? :)
[Xperia Arc General] armadasaxon:

THANKS to the developer :)

---------- Post added at 05:06 AM ---------- Previous post was at 04:51 AM ----------

Does CM9 FXP116 fix the 0% battery issue?

Anyone can comfirm?
[Xperia Arc General] ST4YSTR0NG:
@armadasaxon you're the one who posted that the CM rom works damn perfectly fixing 0% battery issue but I don't think there is a fix for that one.
[Xperia Arc General] armadasaxon:
Hmmph..the 0% issue is the PCB board problem..It cannot be fixed and they will sent back to SE..they will warranty you a new board...

What i meant now was that the cm7 fxp047 fixed my problem faking 85% battery.

I thoughth my prhone was dead forever.

Now im using zdidhu ICS beta..really superb and the fuel gauge thingy helped me monitor the battery.

The problem can only be fixed permanently by taking it for warranty..but if u r pro,u can fix the battery chip behind where other ts was talking about.

cheers.

[Xperia Arc General] phantnang:
dear bazoocaze! The APK V1.6 works well on ICS , but usually FC error appears.

You can remove the features "set battery to 100% on charger disconnected"? Because sometimes the battery is not full charges but APK still set 100%.

Well... I tried zergrush's root and battery patch method for locked bootloaders on fw .42 but it doesn't work with ics. So, there is no way at the moment to patch ics without unlocking the bootloader.
[Xperia Arc General] samirborelli:
I Have a question,

little time behind mine arc showed 0% one day after I flashed firmware .42, later making root, and upgrade OTA for .62

And when this problem happen i couldn't charge the battery through the phone, because it showed a red light beside the charger sock and the screen showed like it was charging, but 1 hour later, i tried to turn on the phone and it started normally until the lock screen apears and the battery icon show up empty and rounded with a red line and showing 0%. So I took off the battery and put it to charge in a external charger.

Put back in the phone and now it is charging since my phone is turned on, but when it turns off due the low charge of the battery, i need to take off the battery and charge with the external charger again.

May this problem be the same fuel gauge problem?

I'm asking, because i'm having 0% everytime my phone turns off due to low charge.
[Xperia Arc General] uchan_flash:
Hi Bazoocaze

this is log of my lt15i 0% battery please help me
[Xperia Arc General] steryman:
Yes it is. Anything you try to do(except patching the battery driver), the battery still shows 0%, so the only way to "fix" it(it's not really a fix, just an emulation) is to patch your battery driver either by unlocking your bootloader and flash a patched kernel or by following Z's patching method for locked bootloaders .42 based on zergrush rooting exploit.
[Xperia Arc General] Morrru:
Hello everybody,

Recently I've got some battery troubles wit my Sony Xperia Arc. I've loaded the 62 firmware and the boot.img so that it works now. Anyway, there is still an issue with my battery, it seems that it does not charge properly. Apart from that, it shows 85% all the time and it looks like it can't charge over, roughly saying, 30/40% and therefore it turns off faster, as the result of the lower battery level.

I've downloaded FuelGaugeFixV16, but i don't know how to install it.

Can anybody plz give me some advice on how to manage with this problem?

Thanks in advance,

Mor
[Xperia Arc General] jasousa:

[Xperia Arc General] Morrru:
Thx for ur help. I'm using 2.3.4 so I've loaded the fuelgauge apk only. Even though it does not show the true status of my battery, the apk allows the battery to be charge properly.

The modules u have provided in this package are for 4.0 android, so i'm afraid i cant use them on my arc :/. Anyway the apk is ok, still better than nothing :).

[Xperia Arc General] Bazoocaze:
Hello there, I'm back. I'm currently suffering from an anoying health issue, so you will see low activitie from me on the forum for now on.

Anyway, I will be monitoring the Sony servers for the ICS 4.1.B.0.431 Kernel source, so I can make an official kernel 0% issue patch.

Until Sony deliver the 4.1.B.0.431 kernel source, I can´t make a reliable official patch, so you must stick with other ROMs (DoomKernel, ...) if you want to use ICS.

Also, you can try to use the latest patched kernel from first post and try to use ICS with that kernel. There is a chance it works, because Sony choose to use the older GB Kernel with the ICS update to speed things up.

Isn't the the CM9 supposed to be patched for this bug? Because I downloaded the latest release I found from here:

http://download.cyanogenmod.com/?device=hallon&type=nightly (update-cm-9-20120404-NIGHTLY-hallon-signed.zip)

but it still had the bug.

I had to download a new kernel separatly (took that one:http://xdaforums.com/showthread.php?t=1566871) to make it work.
[Xperia Arc General] nayanasri:
As far as we know this is not a bug. At first a design architecture bug may caused this problem. But that bug damaged the "fuel gauge chip" (hardware) permanently. That's why a firmware update cannot fix this. You need to replace the damaged chip from phone's motherboard for a permanent solution.

See the attached pic.
[Xperia Arc General] honj90:
Thanks for your reply, it clarifies some things, but unfortunatly doesn't really answer my question. To rephrase it, doesn't the kernel coming with CM9 have the workaround already implemented? According to the original post it should, but the 2012-04-04 release from this link didn't do the job for me: http://download.cyanogenmod.com/?device=hallon&type=nightly

Is there any other place with more recent versions of CM9?
[Xperia Arc General] Bazoocaze:
If you want, please ask CM9 developers to include the workaround patch. If enough people asks for path inclusion they should do the job.
