[Xperia Z Q&A, Help & Troubleshooting] tiltme:
Has anyone found a solution of new firmware (custom or stock)

that fixes this issue where you have no idea of your battery

level and your battery can be ruined because it drains too far?

Can anyone confirm if SONY is aware of this major problem?

How do you use your device with this issue? Any tricks you use

to live with it?

Can anyone confirm when they upgrade to firmware 4.2.2

ie: 10.3.1.A.0.244 or 10.3.A.0.423

they have killed their battery completely?

(ie: it won't take a charge anymore and the phone is ruined?)

> It happens when your battery is 20-35% and u do a battery reset (power+volup)

SO, as long as you don't do this, you don't get the bug?

-Why are you performing this action anyhow?

-Why not just hold the power button and restart your device that way if needed?

Can anyone confirm if a regular reboot (using either the reboot command from terminal or by using an app to reboot) also triggers the bug?

> Installing the 4.1.2 binary does NOT fix the issue;

What if you roll back to stock 4.1.2, or you are on 4.1.2?

Is the bug for sure not there?

Is the bug just on all versions so far of stock and custom 4.2.2?

Is the bug on 4.3?

Does the bug cause the device to think there is more charge than

the battery actually has, thus draining it too low and killing it?

What is the best way to fix the bug once it occurs and is

there any way to tell if the bug is occurring? Someone mentioned

charging it all night is the only way you know you are at 100%?

What devices is the Battery BUG on besides SONY XPERIA Z (ie: model C6602)?

So, to live with this bug, never reset your device, and if you do,

do it before you put it on your charger for a very long time?

Btw, how long would it need to be on the charger worst case?
[Xperia Z Q&A, Help & Troubleshooting] MinedSafe:
Battery bug is most likely due to battery stats. Once they are cleared/ reset then the bug goes away. See if u can reset them in cwm or twrp. It has nothing to do with the hardware. I always flash roms on full battery and never had that bug.
[Xperia Z Q&A, Help & Troubleshooting] kingvortex:
Wiping battery stats does nothing.

I found a solution don't reboot or turn off your phone :D
[Xperia Z Q&A, Help & Troubleshooting] MinedSafe:
Maybe I didn't got the bug because last time I had to was about a month ago, when flashing new rom. Well I did flashed some mods as well. Maybe reset stats while on 100% and flash new rom.
[Xperia Z Q&A, Help & Troubleshooting] kingvortex:
LOL. Resetting stats does nothing! It deletes the batterystats.bin file. That file is deleted every time your phone is charged anyway and doesn't have any effect on the battery percentage that is displayed.

Please read the article I linked you to earlier.
[Xperia Z Q&A, Help & Troubleshooting] emrause:
I never had the battery bug!

I've a C6602 and from the original 4.1.2 and the following updates (now the 4.2.2 [0.244]) always the battery was correct!

I've also used all the above-mentioned method of reboot...

because of some games (specially Let's make pottery) and reboot to CWM or normal Reboot with Powerwidget never made the bug!

hope that helps!

MAJOR BUG Check

Odd. Some people have this MAJOR BUG and some do not??!?!

I will upgrade my UNITED STATES phone by flashing an .FTF.

I'll see if I get this BUG or not. Anyone have a link to

C6602_10.3.1.A.0.244 .FTF for UNITED STATES that doesn't

think they have this bug?

> u shud calibrate the battery in order to get exact output.

Anyone know how to do this?

emrause- you say you don't have the bug on 0.244.

Did you flash your .ftf and which one did you flash?

Are you on stock rom? What is your region?

sebastianlow-

I have read several posts that the bug is still there in the 0.244 thread.

Is it gone for you and did you flash the .FTF? Which one?

> It seems that Spanish FW is free from this bug.

I thought if we flash the .244 .FTF there is no difference in regions!?

Can we safely flash it to our United States phone?

Anyone have a link to it? Will anything change to Spanish?

Does anyone know where to get the latest good .244 .FTF

10.3.1.A.0.244 that we can flash to our United States phone?

I was going to use C6602_10.3.1.A.0.244_Generic India.

Is this one not good and Spanish one is?! Will it change

our keyboard or language or radio stuff incorrectly?
[Xperia Z Q&A, Help & Troubleshooting] tiltme:
kingvortex- Do you have the bug? Which firmware are you using and did you flash a .FTF?

Did you roll back to 4.1.2 or are you living with the bug?

As long as we don't reset the phone around 20-35% with a battery reset (power+volup)

are we ok? Also if we do reset, just put it on the charger for a long time?

Anyone know how long it takes to fully charge a SONY XPERIA Z roughly before it

switches to trickle charge on the standard US plug adapter?
[Xperia Z Q&A, Help & Troubleshooting] tiltme:
Anyone have quick answers to any of these or any input on this battery bug?

I'd like to flash the latest to my phone. I have a United States Phone.

Is flashing an FTF a good way to update? What method and

which .FTF should I use? Does the region matter? Anybody have any ideas or links?

Anyone know if the New firmware: 10.3.1.A.1.10 addresses this BATTERY BUG

or is this MAJOR BUG still there?

TIA

My xz has battery level bug with 4.2.2 423 and 244 versions. it had not any bug when 253.
[Xperia Z Q&A, Help & Troubleshooting] tiltme:
Does 10.3.1.A.1.10 fix it possibly?

Do they list frmwares and what is in them anywhere? (ie what fixed)

Also, how do you live with this bug? ie- what do you do so your battery doesn't get ruined and so

you know when your phone is running low if the battery indication is not reliable?

Is the trick to this bug to never reboot your phone during the day and if you do, always charge it

for a long time (ie 100% plus trickle charge) and then the battery is always correct?

This is a pretty major bug. Does SONY know about it?
[Xperia Z Q&A, Help & Troubleshooting] tiltme:
kkd28- Are you going to roll back to another firmware which does not have the bug?

Do you never reset your device so the bug isn't much of a problem for you?

Anyone else roll back because this battery bug is so bad?
[Xperia Z Q&A, Help & Troubleshooting] asrail:
Anyone suffering from this bug can kindly post here a few debug info about the battery?

Those relevant files are on this folder: /sys/devices/platform/msm_ssbi.0/pm8921-core/pm8921-charger/power_supply/battery

The charge_full, charge_now, voltage_now and capacity are the relevant ones. The the last one should be the same number as the capacity listed on the Android user interface, but it wouldn't be true if it is a ROM issue rather than a kernel one.

It is possible to analyze the health of the battery with those numbers. There is also a health file on that folder, whose content should be "Good" otherwise you are on a bad shape.

It should be noted that Android will use the current voltage, not the current charge, to decide when to turn off or stop charging a battery. Also it should be noted that as long as the battery is healthy, there is no risk ruining it even with a bug on Android. Those batteries have a swicth which will be activated in case of low voltage and it will suspend the power supply.

There is no risk in ruining your battery except you are draining it too quickly.

It would be even better if one could post the content of those files right before and after the bug happening.

[Thinkpad Tablet General] sammymaddog:
have you chmod-ed the busybox (or is the chmod successful without error)? Try chmod-ing the /cache before attempting step 13. It seems that you still don't have access to the NAND device (mmcblk0). Have you updated firmware via OTA?

Do you encounter the same error message like ulisez had? Could you post the screenshot of the partition list (the lines after you execute dumchar_info)?

I personally use Link2SD by Bulent Akpinar to link apps to 2nd partition on my SDcard.

The original developer who posted the method (entonjackson) plans to integrate the method in the next release his toolkit, the Acer Iconia Toolkit. I think you should check his thread : http://xdaforums.com/showthread.php?t=2240029

[Thinkpad Tablet General] sammymaddog:
I'm not sure whether the stock kernel of our devices supports init.d, thus supports CronMod/Data2SD. Lenovo locked our bootloader, and currently there's no way around it. So I personally think, Link2SD method are the best option for now.

Let's give it several months until our dev gurus bring their miracles upon this device :D
