If I understand correctly to use this patch correctly I can only charge while the phone is on.

I was under the assumption that we shouldn't use the phone at the same time while charging. So I thought turning the phone off will prevent that greatly. I was worried about an incoming call while it's charging.

Before the 0% issue, I usually charge the phone on the plug overnight. Will it still be safe to do that now? I'm afraid of overcharging
[Xperia Arc General] errIO:
overcharging ?

when % reaches 100. it stops charging because the % is not changing periodically.

think about your laptop. you goto sleep and leave it on charger plugged in. and it after months, battery is still good.

overnight charging

Hi.

I'm am going to mod the apk to enable overnight charging.

In fact, battery stops charging if the percentage is not changing periodically.

What i'm going to do is set the battery percentage to 99% when it reaches 100%.

I know it's a bit risky but, our phones are already dead.

I need help in apk modding.

Thanks

Is my Fuel Gauge broken?

I have Neo V and I am stuck on 1% battery.

Battery Calibration app shows I have 3333 mV and around 3450 when I plug in a charger, but I still cant get above 1%.

Is this an app for my issue or is my battery is broken? (usb cable? usb slot in phone?)

Hello,

i just went to that crazy 0 battery problem and find that solution.

Even if it works, my girlfriend is unhappy :( she sais : the phone went out of power without using it in about a day :( whereas before she had 3 days power (without using it ^^ )

she has an xperia Neo.

I saw in the apk that i can change some values, but i have no idea what ?

any idea what value i can change to have a battery that works like before ?
[Xperia Arc General] errIO:
Lower the "Charger" value. Default value is 450 000 µA.

Battery stops charging if value is not chaning periodically. So, if it reaches 100% it will stop charging.

So, i set the charger value to 300 000 µA so it can charge longer without having to unplug and replug the charger.

I don't care if i'm "overcharging", I can considere my phone is already dead without a working battery gauge.

If your battery is full and continue charging. It will be full as long as it is charging.

2 months that I use this trick.
[Xperia Arc General] beiurh:
hmmm.. Srry if i wrong ...i'm new but i follow this guide, try to make some test with programs to show the usage of cpu during the charge and overcharge. u will see the processor work during the charge and overcharge so when u go to 100% fullcharge is right to see battery level decrease bcause (i think, i'm not shure) in overcharging cpu consume.!!

[Xperia Arc General] errIO:
Battery driver (in a working phone) is made so the battery level stays between 90% and 100%.

BTW, my phone is not heating when i'm overcharging.
[Xperia Arc General] lmiguelsp:
Final solution for neo 0% battery!!!

After so much research, I finally found the solution that works 100%.

Rest ... that is no hardware problem, only software.

So the solution I found was to put the version 2.3.2 build 3.0.A.2.181.

Then install on pc "ZeroPercentFixTool.exe" google it (asansam - download section).

Run the program, select the phone and put the unlock code.

With program running:

On NEO mt15i (phone tested), power off the phone, unlpug usb (phone and pc), select menu button and plug the usb cable (first pc then phone). Now the light is blue...

If you don't have yet the unlock code, simply select "Get Unlock Code"... and wait the code by e-mail.

Good Luck!
[Xperia Arc General] alain57:
does this really fix it ... i mean can the phone read the real battery indicator ?

or does it use the fake battery indicator and set it to a value like other solutions (that are not a real fix... )
[Xperia Arc General] nayanasri:
It seems that asansam team has put together a one click app using bazoocase patch. Nothing more.
[Xperia Arc General] Bazoocaze:
Asansam simple stole the solution from this thread. There is nothing new about that.
[Xperia Arc General] Bazoocaze:
Extracted from the first post:

[Q] What kind of failure is this 0% battery issue?

[A] This is an unrecoverable hardware failure on the fuel gauge controller of the Arc/Neo. On our research, we concluded that no software can correct this.

No software can correct this, so this is a WORKAROUND.
[Xperia Arc General] Bazoocaze:
Nice solution.Congratulations.

In fact, when the real charge reach 100%, the battery charger chip (don't confuse with the "dead" fuel gauge chip) stops the battery charge. If the Fuel Gauge App was configured to, it can set the software percent to 100% in this condition.
[Xperia Arc General] Bazoocaze:
The .img file is for flashing on an unlocked bootloader, using the fastboot tool. It doesnt work like an FTF, therefore renaming the file will not work.

See the first post for instructions on how to patch a locked bootloader phone. I think you need the "locked bootloader patch" (but first you need root on your phone).
[Xperia Arc General] Bazoocaze:
Updated the FAQ with this entry.

Thanks.
[Xperia Arc General] Bazoocaze:
3.450V is below the safety battery threshould opetarion range, so you must charge it a bit (I recommend 3.7V) and see if the percent goes upper from 1%.
[Xperia Arc General] errIO:
Is it possible to set "1%" battery instead of 85% on boot?

So if my phone is turned off, it will not stop charging because of "negative variation" when FuelGaugeApp starts.

It's not really working for me. And can anyone answer my question. Will I resolve the problem with a new battery? Or I should just buy a new phone? :(
[Xperia Arc General] worf_1977:
It's a problem related to a firmware downgrade who breaks the fuel gauge chip controller...

It is almost like frying your phone, and you will experience the same with a new battery.

The only option you have is to get it to Dony's nearest service center and pray for a board replacement...

BTW: this issue voids your warranty, so i think it's better to buy a new phone as i did

Thank you for replying. Now I know exactly what I did with my phone. I have unlocked bootloader using SE method so I don't have warranty anymore.

My phone gets back to 0% each time I turn it ON

Please help me, I read the whole post and (I think) followed the prescriptions of fixing my 0% battery issue on Xperia Arc.

I installed:

* ADB and Fastboot drivers installed and configured.

* LT15i_4.1.B.0.587_Generic Global World (by Flashtool)

* Unlocked bootloader

* Run ARC Autoroot v1 (My charge percentage jumps to 85% - my battery is fully charged)

* Download Full Gauge Fix from Play Story and run it (My battery jumps to 100%) and set it to load on startup

But!!! if I restart my phone, I get my 0% back and the phone terns off.

Is it normal, since I didn't see anyone complaining about it.

Is there a solution for this thing?

Please post it here, since I am sure there are a lot of people like me suffering...

Hi,

It would be much easier if you flash free xperia project's cyanogenmod rom.

Battery patch is integrated to their Cyanogen Mod 10 release.

https://sites.google.com/site/projectfreexperia/download/cyanogen-mod-10

After flashing their rom then you can install the fuel gauge fix from Google play store.

https://play.google.com/store/apps/details?id=br.bazoocaze.fuelgaugefix.free&hl=en

Cheers.

N.B. I myself currently using this method on my Arc for a few months. :good:
[Xperia Arc General] mirud:

I have already started to download the ROM. It will take an hour to download it and then about 15-30 minutes of work.

I will update here about the results.

Anyway, thank you very much for the advice.

Michael

It worked. This way I can go on and keep my phone.

Although it is not 100% fix, but is a decent workaround to keep using the phone.

If there would be any solution, to fix it permanently, I would be more than interested to test it :)

[Xperia Arc General] nayanasri:

To fix this problem permanently, you need to replace the fuel gauge chip;

[Xperia Arc General] mirud:
Where can it be purchased?

Thank you VERY much for your note!

I defiantly would like to re-use my phone fully, but since it is now unexpectedly can die, I try not to use it often.

I have several questions before I do this fix:

1) How much are you sure that this is the device needed to be replaced?

2) Will it fix the problem permanently?

3) Where can I buy this chip?

4) Do I need special equipment or previous knowledge to replace the chip?

Hi Bazoocaze,

any plans for making a patch for 4.1.B.1.13 ?? :)

OR

for the 4.0.2.A.0.84 :D

or anyone here with the knowledge to do so ??

---------- Post added at 03:39 AM ---------- Previous post was at 03:14 AM ----------

Hi,

1) I got the pic from this thread. Someone with the hardware knowledge posted it few months back.

2) They say so. :)

3) Apparently TI is not manufacturing it anymore. But you may check with your local phone repair center.

4) Yes. As this chip is only 2mmx2mm in size, the process is very delicate. You need a hot air gun for soldering.

My advice is, don't do it. :cowboy:

There is a risk that your phone may die on the table.

or if any phone repair center is willing to take the risk, get the job done by them. ;)
[Xperia Arc General] mirud:
Thanks again,

Your advices are very appreciated! I think that if this replacement needed to be asked from the carrier center AND the job must be performed by them, the price it will cost would be somewhere like purchasing a new device without any problems and with no "human" touch.

Thank you,

Michael

Hi, nayanasri

I am downloading the kernel source for the 2 versions.

Furthermore, I need the original firmware download for the 2 versions. Can you point me out the links for the 2 ftf files.

Nevertheless you can try to use the locked bootloader patch in these versions. You can edit the script and change the version string from .587 to 4.1.B.1.13.
[Xperia Arc General] nayanasri:
Hi,

It seems there is no ftf file of 4.1.B.1.13 out there. Maybe it's a branded rom for a service provider.

However I've flashed .587 generic global world and it's update center says phone is up to date. :confused:

PS. I just got the donate version of Fuel Gauge Fix. :good:

Hi, Bazoocaze thank you for saving the world...

It is possible you install a kernel without offline charge?

Because I'm afraid of not fully bricking it and I'm trying to make the CM7 Kernel to work by copying the bq27520 folder in sys/class/power_supply from this patch to that kernel but I still can't get set_capacity and some other files of it... Because when I try using "echo n(any number from 1 to 100) > /sys/class/power_supply/bq27520/set_capacity" it says directory doesn't exists or something like that and I think if I'll copy that folder on the CM7 kernel maybe I'll be able to set the battery percentage so I'll be able to use it without charging my phone

This would explain why replacing the bq27520 chip helps, because it's reset to a compatible firmware. So maybe resetting the i2c bus to it's previous settings could help.

By default doesnt the battery not charge to 100%? I thought with the Li-Ion batteries they are never supposed to go to 100% charge? Or am I confusing things?

may be the phone calculates the time that the battery takes to reach 100% from 85% and once this time elapsed, the phone considers he doesn't need charge anymore.

The same as mine.

Just about 5 minutes after I connected it to the charger, it stopped charging.

Please know that I charged it for 3 hrs. Use it for 2 hrs of recording video and shooting picture.

[Xperia Arc General] SireJoe:
Curious. With the 1% my charge seems to never go off. Indicating that it shouldnt be a timing issue. Yet the fact that it stops charging after x amount of time for others, would indicate that something somewhere is telling it its time to stop. Why the contradiction I wonder?

Maybe there is a difference beetween the two patches. And it seem this issue does not appear on all fones (I haven't this issue).

ok after changing the battery indicator to show 50% phone still charges the same ammount of time when it showed 85%, so i think it's not calculating the time for a full charge... that is odd, so something is still working inside, that is making a cut off. i have posted a second output report after flashing it with 50% and charging it to see if there is any difference between 85% and 50% indicator.
[Xperia Arc General] danielnghk:
hello, you said that:

Either way, avoid charging the battery and operating the phone at the same time, to minimize the heat generated during charging. Also, please charge the battery away from the sun or hot spots, and no more than three hours on the charger.
