A question for my current situation but one thing first, excellent work here at the xda.

I watch now the apk 152 since two days. I have 1 hour loaded the phone, to set full battery, the neo worked 10 hours, 7 hours actively: backing up, apps download, install, testing, etc., until the shutdown with warning for shutdown, 3 hours loaded, neo is runnig, but since approximately eight hours with 1 %. It should be noted that wireless. Patch running, status success.

Just it also was completely at the beginning when I have bought it (4.0.1. A.0.283). two weeks ago updated via SEUS to 4.0.2. A.0.42, battery correctly displayed without 1% phenomenon.

is this a smart consideration for further investigations in relation to the 0% value problem? if not, simply don´t answer ;)

---------- Post added at 01:04 AM ---------- Previous post was at 12:38 AM ----------

i verified the status some minutes ago, 98% and decreasing.....what happend :confused:

Edit:

First of all have to correct: phone shut´s down "without" warning from os!

Info:

- I leaved the phone alone tonight :-)

- maybe one hour ago I unloaded the the battery by playing around

- the 98% decreased approximately two times faster as described before

- after reboot the apk shows 22%

- startet full charge right now with 2 %

i resume: I can live with my current neo very well. if it helps, I send with pleasure log files
[Xperia Arc General] peacekeeper38:
i was using using apk 1.5.3 for 2 days and always the phone shut down at 48% the first day and the second day it shut down at 42% so i stopped monitor cleared the data and unistalled the apk, and then installed again and the same happened, it shut down at 46%, so i decided to go back to the 1.5.2 ver. and now the cell its working excellent, at this moment its 36% and decreasing but the phone its working normally, probably its a bug as you said Bazoocase, maybe you can check again if you have time.

good job Bazoocase at least we can have ours arcs on the street for long time.
[Xperia Arc General] mehdi.xterra:
i have same problem with 1.5.3, and i unistall the 1.5.3 and install again 1.5.2 version and my phone work correctly
[Xperia Arc General] lungocphu:
The same problem with 1.5.3, my phone shutdown at 29% battery

I hope Bazoocaze will fix it soon
[Xperia Arc General] Bazoocaze:
:confused: I compared 1.5.2 and 1.5.3 for differences, and found nothing but the set battery to 100% at end of charge feature. I also looked for bugs or others things that can cause a charging malfuntion, and found nothing.

So, I believe it's the new feature causing the charger malfunction. :cool:

To try to solve this, I moved the new feature to the charger disconnected event, instead of the end of charge event ;) . Therefore, the battery will be set to 100% when you disconnect the charger after a reasonable charge time.

Please, test this, and report if it works. If it won't work, please report the charge time you set, and the "end of charge reason" shown on Apk fix.

Sorry for this anoyance, guys.

And please remember that the APK is an aproximation of the real capacity consumption, so it will never be that perfect like the hardware fuel gauge. Don't forget that it doesn't take in count the CPU clock/CPU usage, among others, so if you has a hard usage / music / games / etc the Apk fix will miss your usage a lot and your battery will be empty some time before getting a low capacity display.
[Xperia Arc General] DAVIDSIKH:
Hello, firt of all thank you Bazoocaze for your pachted kernel and apk. But as we know its not good as hardware fuel gauge. So, i decide to change it. I bought two of them on avnetexpress.avnet.com, they cost 4$ per chip + 8$ shipping. they arrived in 2 week. I resolder broken fuel gauge, and solder new one (you will need simple soldering station and some flux). after that i flash my phone with seus, turn it on and its working perfectly. (because of i dont have enough posts, im not able to post photos)
[Xperia Arc General] keiloff:
that lookes interesting, is it possible to do it by myself. when yes tell us please.

thx

soldering station and some flux is right behind me :-)
[Xperia Arc General] 7hr08ik:
Awesome, that handy to know
[Xperia Arc General] DAVIDSIKH:
yes of course if you have some experience with soldering :) I do it by myself. chip is very small and thats why its easy to desolder it without of risk overheating motherboard.
[Xperia Arc General] Bazoocaze:
The chip is BGA? I think the replace of the fuel gauge is the best solution, but I guess soldering with a BGA chip is way to dificult.

What tools have you used? Can you make a tutorial?
[Xperia Arc General] peacekeeper38:
Hi Bazoocase!!!!!!!!1 downloaded and testing the new apk, later ill report to you.

thks

---------- Post added at 02:49 PM ---------- Previous post was at 02:48 PM ----------

Yeah a tutorial would be so perfect, and thnks for the info
[Xperia Arc General] DAVIDSIKH:
Yes, chip is BGA, 15 ball. I desolder the chip with soldering iron, to keep motherboard as cool as possible, but install new one with hot air rework station. its possible to solder new chip with soldering iron but with hot air its much easier. Will try to make tutorial tommorow.
[Xperia Arc General] wakanars:
Hi DAVIDSIKH

thank you for sharing.

i am thinking to do the same thing.

Which chip should i buy from TI?

do i have to do anything with the FW with the chip before i replace it?

Also, what FW or ROM should i put on ARC before i do this?

thanks again!
[Xperia Arc General] DAVIDSIKH:
You should buy BQ27520YZFT-G1. You dont have to do anything before replace the chip, but after you should reflash with seus, chip needs firmware updating. Do not turn on the phone before updating. Also be careful with soldering, don't overheat the motherboard.
[Xperia Arc General] wakanars:
Thank you again!

one question, the chip is BQ27520YZFT-G1 not BQ27520YZFR-G1?
[Xperia Arc General] rajubnt:
Hi I have neo, is BQ27520YZFT-G1 fuel gauge is same for neo? please...
[Xperia Arc General] DAVIDSIKH:
Yes, arc and neo have same fuel gauge chip. I have neo too, so BQ27520YZFT-G1 is what you need.
[Xperia Arc General] keiloff:
is it posible to paste screenshots from position of chip and difficulties for example, just to be sure.

thx for the help.
[Xperia Arc General] DAVIDSIKH:
I was asked about differences between hot air soldering and soldering with iron. In first case you are using special gun, wich blows hot air, so you did not touch the chip, its better if you have to solder BGA chip but you should be careful with overheating motherboard. In second case, you are using hot metall to solder, so its too hard to solder BGA chip (its possible becouse of very small size of fuel gauge chip).
[Xperia Arc General] steryman:
Ok then tell us how to prevent overheating the motherboard too when soldering the chip :)
[Xperia Arc General] mrverna:
First of all, thank you very very very very much.

Now I can use my Arc. :)

Fuel gauge are very very very useful. (Thanks again.)

And I'm South Korean user, please understand my poor English :(

So, no more update? I'm waing 9 days.......since 21.nov

I'm expecting new kernel5 or new fuel gauge 1.5.3.(or 1.6)....the better solution :)

I'm sorry about hardly request..sorry..

Anyway, F I G H T I N G ! !
[Xperia Arc General] Shinyweed:
Why not have the app set the battery to 99% when the charger is plugged in?
[Xperia Arc General] keiloff:
15 balls means that there are 15 pins to solder, right? how big is this chip? and is it possible or helpful to wrap the phone into an kitchen towel with gel-icepacks to cool it down a little? dangerous work....

but maybe it is possible to reunlock the boatloader and flash the phone so i can bring it to service and tey give me a new one - hope dies at last :D

thx for help
[Xperia Arc General] DAVIDSIKH:
Yes, that means there are 15 pins to solder. Chip is very small, about 2x2 mm.

[Xperia Arc General] peacekeeper38:
hi Bazoocase you are back!!!!!!! good to read from you......... i thought you let us alone after the suddenly change on the thread with this soldering the fuel gauge to fix the problem wich is excelllent for those with the opportunity of doing, but for the rest of us that we dont have the chance to do it in that way is good to know that you are still there to help us!!!!! thank you very much really appreciated for your job.

right now i am downloading the v 1.5.4 and installing on the arc.
[Xperia Arc General] SireJoe:
So I got my phone back after getting it repaired. It works again, but the battery status is all over the place. It does discharge, and it does recharge, but when it is at 100% its at 100% until its dead. Im probably going to have to bring it back to them again....

Anyone else have this issue or know of some type of fix maybe?
[Xperia Arc General] SireJoe:
In fact, my battery level is increasing while I use it! *sigh*
[Xperia Arc General] alex7532:

What is new with this update ?

I don't know if I could do it but I'm waiting for the tutorial too ! ;)
[Xperia Arc General] redstorml:
Do you think that there will be a problem if i try with G2 since the only difference between G1 and G2 is firmware version?
[Xperia Arc General] keiloff:
A question about recoveryneo.img tool please. Where does it store it's images of the phone? And when they are on system-partition, will flashing new firmware delete them?

Bazoocaze, version 1.5.4 discharging many times (after phone shutdown because of empty battery, plugin about 10 mimutes, it discharged and set 100%
[Xperia Arc General] DAVIDSIKH:
It should run as well as G1 but i can't guarant that. Anyway, i will recomend to use G1, i already try that and it's working as original one.

[Xperia Arc General] memoHDCV:
Thank you very much Bazoocaze!!!

Im using this workaround to solve the problem in my Arc and it is useful, I'm actually having problems that it turns off at 70% of the battery with the v1.5.2 and v1.5.3 of the .apk but I will use the v1.5.4 and see what happens. :D

Regards
[Xperia Arc General] itachi naruto:
Bazoocaze have stopped developing software
[Xperia Arc General] Bazoocaze:
Hi

Install v1.5.4, and don't forget to select "Start full charge" on APK menu to force a full charge starting from 1% battery (select the menu option before connecting the charger).
[Xperia Arc General] Duvel999:
If I were you, buy the chip & go to a Mobile Phone Repair Shop.

Let them replace the chip for you..
[Xperia Arc General] keiloff:
A really good idea! Thank you. But I hope, i can use the warranty and hope for goodwill. As said before: hope dies at last.

However, Thank you, this will be the last option when warranty fails.

Have a good time.
[Xperia Arc General] memoHDCV:
Thanks for the tip, I installed the v1.5.4 and used the "start full charge", connected the cable and everything is fine at the moment, 36% and still working.

Let's see if it can reach tha 10% mark without shuting down.

Thanks again!!!

P.D. And sorry for my english :P
[Xperia Arc General] peacekeeper38:
is it true? Bazoocase stopped developing solutions? bad news for us!!!!!!
[Xperia Arc General] Bazoocaze:

Hi Bazoocase good to read from you friend, hope everthing is alrright with you.

just to inform you the the ver1.5.4 is working like a charm on the arc and see what news do you have with this issue?:D
[Xperia Arc General] heidality:
Hi)

Hi.Do you think ICS fix ours problem?Or no?
[Xperia Arc General] Bazoocaze:
My objective on this issue is that one install patch+FuelGaugeFix and forget about it, using his/her phone like (almost) before the 0% issue. I wish one can charge his/her phone and use it during 1 or more days before battery is empty.

This way, I´m focusing on the charge process, not on the % charge indication. The apk % display will never be perfect, because it is impossible to determine real current usage during gaming, music, and other intensive tasks, but for normal usage it will be ok.

About ICS, it will not solve this issue, because it's a hardware failure, so your best effort is to replace the deffective fuel gauge chip with a good one.
[Xperia Arc General] Bazoocaze:
I update the first post:

- Updated patched MIUI kernel, from Jason.

- Updated apk version v1.5.4

- Updated APK issues.
[Xperia Arc General] memoHDCV:
I have been using the v1.5.4 and i haven't had problems, is there gonna be a patch for ICS too? :)
[Xperia Arc General] mehdi.xterra:
dear bazoocaze thanks again for your work, i have a question, can u create patch for ICS after release this update for xperia arc?
[Xperia Arc General] Bazoocaze:
Yes, for sure. We will have a patched ICS kernel if Sony continue to publish the xperia phone source code.
[Xperia Arc General] nigeta_gr:
Dear bazoocaze, I cannot clear in my mind the steps I have to follow.

After appearance of battery 0% problem the only rom which keeps my Arc alive is the japanese Domoco 3.0.D.2.79 (Android 2.3.2 version) which I flashed to it and which allowed me to root phone.

Now, I wonder if there is a way to install a clockwork recovery to my phone as i suppose that probably a restore of my previouw ROM could solve problem.

I have a lot of doubts that it can work, as everybody on this forum supposes that this is a hardware failure but I would like to try it as a last chance. You think that there is a way to install clockwork recovery without loosing my phone's functionality?

Otherwise what could be my next steps to install a newer Android version keeping my phone rooted and obtaining your patch working?

Please, excuse my questions but I'm not familiar to the Android environment.
[Xperia Arc General] Bazoocaze:
You may get 0% battery issue after a downgrade of firmware. If it is the case for you, follow the steps on FAQ "[Q] I need this patch?" (on first post) to see if your phone comes back to work.

If your phone doesn't come back to work, then you have the infamous unrecoverable hardware fault on the fuel gauge - no software can correct this.

To use the workaround we made, follow these steps (it's on the FAQ, too). Don't forget to read the full first post, and the full thread, too.

[Q] What are the steps to apply fix on my phone?

[A]

1. Read the full post, especially the FAQ. In case of doubt, you can use this guide to know how to do things:

http://xdaforums.com/show....php?t=1133650

2. Unlock booloader

http://xdaforums.com/show....php?t=1034087

3. Grab the most recent kernel patch from this thread. The file is boot.img.xxx.7z for your phone (ARC / NEO). We call this the kernel patch, or only the patch.

4. You must be same firmware and patch version, so if you aren't firmware xxx, use flashtools to flash the correct firmware. and wipe the data if downgrading firmware version. You can find some recent stock firmwares in the [Firmwares (.FTF)] section.

http://xdaforums.com/show....php?t=1304634

5. Use fastboot to flash boot.img contained in file boot.img.xxx.arc.7z (or boot.img.xxx.neo.7z for NEO users). Flash the .img file, not the .7z file .

http://xdaforums.com/show....php?t=1116970

6. Now you have a phone showing allways 85% battery capacity

7. Install most recent FuelGaugeFixV??.apk from this thread (Bazoocaze version).

8. For the first time, make sure the charger is plugged, and select "Start full charge" from the apk fix menu (use the menu button to show options). A full charge takes 3h00 ~ 3h40.

9. Now you have a fully charged phone, and apk fix updates battery % acordingly to phone usage.

10. See "Kernel issues" and "APK issues".

11. Press the tanks button on this thread, and optionally make me a donation.

http://xdaforums.com/dona....php?u=4215483

12. Finish

After you finish the steps, you can root your phone with the Zergrush exploit.
[Xperia Arc General] nigeta_gr:
Perfect job!!!

Hi..

Im noob here..i want to ask im already had 2.3.4. on xperia neo but the firmware seems too many problem.if i reflash to same 2.3.4 firmware is that i will facing 0% battery problem on my phone?i saw the problem happened if we downgrade it back after upgrade to 2.3.4..
[Xperia Arc General] Dark Stranger:
Nope. The problem occurs if you downgrade to 2.3.2 after you have already flashed your phone with fw 2.3.4.
[Xperia Arc General] SireJoe:
Does anyone know if its possible to install the fuel gauge chip upside down?

It CHARGES when its not plugged in at all. I can actually watch the percentage go up as I use it. At which point it will suddenly die on me as the battery charge is actually 0%, not 100%.

I also need to remove the battery, put it back in and then charge it, as it will not charge at all when it claims it is at 100%.

The battery removal and replacement resets the gauge back to its correct setting.

Fun stuff.

I was told by my store here that they need to send it back 3 times before they consider replacing it. So this should be a fun ride.... :S

[Xperia Arc General] impr0vision:
I very much appreciate all the work everyone involved has done to assist helpless people, such as myself, with this issue.

The workaround worked great for my Neo in the first couple weeks or so, though sadly all of a sudden, my device shuts down within a couple hours of being on.

I've upgraded the battery fix apk to the latest, tried reflashing it, and have tried the custom kernals but for some reason I cannot get past the boot screen.

Any ideas?
[Xperia Arc General] Ninoh-FOX:
Try flashing a kernel that has fix battery first whit fastboot, in the foro you can find kernals from doomlord with this fix.
[Xperia Arc General] Bazoocaze:
Hi,

This update is to calm down those blaming for end of charge before 100%. At kernel level the charging process stops early if battery becomes full charged before the pre-configured time.

And you can connect/disconnect at any time, let's say for usb data transmition, and the stats will only update to 100% if you leave the phone connected for a long time (more than 90 minutes, I think) and the APK detects end of charge before charger disconnection.

About the icon, I did it this way for 2 reasons:

1) To Android not kill the Apk, so it can allways monitor the battery consumption.

2) To the xperia owner not scam someone else selling a deffective phone without warning.
[Xperia Arc General] impr0vision:
Unsure if the doomlord kernal has worked. Yesterday when I got home from work, my phone died, though interestingly it had a green flashing light (or was it blue) instead of red when you try to turn it on.

But then I restarted it through the usb, charged it and set it to 100%, and as of now it's still on.

Hopefully it stays on.
[Xperia Arc General] steryman:
Huh I have some problems compiling DooMKernel for Stock Arc... I receive some errors about net whatever (make net-blah-blah error 2) and it stops compiling and no kernel image... strange... and I used doom_arc_defconfig when creating the make config file
[Xperia Arc General] Bazoocaze:
Yes, the patch should work without changes. Simply overwrite the bq27520 driver (the .c file) and compile your kernel version.
[Xperia Arc General] tanny25:
Hi guys, the problem with 0% resolved, but another came close to itself and to 80% and 30%. You can solve this problem?

Still dies, though maybe lasted a couple hours longer.

Sorry for my ignorance...

But would posting these logs reveal more about my issue:

Do I enter them in the command prompt during fastboot? I tried them but they were incorrect commands...

And am I meant to be using the "bq27520" file? If I am, how do I actually use it? I don't recall it in the steps.
