Ok, so I just found out that I only PM'ed my response about battary life to Tengis.... here it is. Also, mind everyone that we have a quadcore processor vs the dualcore in the earlier S3 models. so think of that before you complain about battery life. same for pcs, you get bigger/better this/that/andtheother, than it will require a bigger power supply... or with cars, if you get a bigger engine, you need more gas.... great phone, but you just need to carry a charger with you or charge your phone whilst you are at work/playing games/or at the bar counter.

This is what I did to my phone to make it as clean cut as possible (I left out all the obvious steps... like factory reset etc.):

1: Flashed the MB1 ROM in my guide

2. Unlocked my phone (I didn't do this when I went back to Cali for vacation and regretted it...)

3. Flahsed CWM

4. Flashed CM 10.1 JP Remix & gapps

5. Flashed the kernal (link in my guide) to get the silly anime boot screen off

6. Installed all my apks and set my accounts up

Use this CPU manager:

https://play.google.com/store/apps/details?id=com.antutu.CpuMasterFree&hl=en

-put the governer on 'ondemand'

-put the I/O Scheduler on ROW (read over write)

Use this battery saver:

https://play.google.com/store/apps/details?id=com.antutu.powersaver&hl=en

this should run smooth!
[Galaxy S III General] JarodCB:
Yeah, that is the thing. It seemed fine in my classroom. Then the day before yesterday at night, I only got up to 58% from 12% or so, in over 5 hours. Tonight, same cable, same power outlet, I came to 100% without problems. I might miss something...

Anyway, thanks for the quick answer and letting me know about kernels!
[Galaxy S III General] IparryU:
at home my charger works like a charm but my office it doesn't... so i changed the cable and it was just fine. it is usually the micro USB connector that is the issue.

i have done that a few times now and it actually gets charged.
[Galaxy S III General] kizuki.buy:
I am not sure if this is a kernel problem or is it a h/w issue, but I have seen similar issues with 3 different sc-03e units (each having their own cables and wall chargers).

Basically all of them would charge fine (taking maximum of 2-3 hrs for full charge) when charged from a threshold of 20-30% remaining battery.

But on multiple occasions, once the battery level reached 10-15%, invariably it takes forever to charge the battery. e.g. Once I plugged in overnight with 10% remaining and next morning it had charged only up to 48%. I have tried with different cable and wall charger but same end result.

On 2-3 occasions, after observing for an hr or two that the charge was not happening properly, I yanked off the battery, waited for 5-10 mins and again tried charging, and it worked fine after that.

By the way, I faced this problem while on stock, rooted stock and CM10.1 (both anime kernel & non-anime kernel)

Thanks for testing it out. Shouldn't be too long before we have something. The kbc guys are hard at work. The standard s3 already has a working version.
[Galaxy S III General] IparryU:
I will also test the 08.07 nightly for CM 10.1 tonight when I get home. When I flashed 07.30, the sound was not working.

we'll see what happens!
[Galaxy S III General] Tengis:
I am constantly having issues with battery life and its getting ridiculous. So far four different roms give me terrible battery life.

The only rom that even barely worked for a while was a random nightly of CM but after two days my battery life went to absolute **** again. I cant figure out whats draining it so that I can attempt to fix it.
[Galaxy S III General] DroidZombie:
What does your battery stats say?

Willing to bet screen is at the top. This is one of the disadvantages of amoled screens. They look beautiful, but they are vampires. With my brightness on high I can literally watch my battery icon tick down to zero.
[Galaxy S III General] Tengis:
Screen is not at the top and its usually about half of what is at the top... Android OS. It will usually show 60% usage or so.

I maybe use my phone for all of 30 minutes in a typical day and my battery drains about 10-12% an hour with zero use while in "deep sleep". From 5am when I unplug it to 5pm when Im sitting at home on my computer it will be around 5-8%.

There have been times for an entire day I will get awesome battery life. From 5am when I unplug it to 5pm when Im sitting at home on my computer it will be around 65%.

I dont know what changes during the days that I get awesome battery life but its very rare.

---------- Post added at 05:02 PM ---------- Previous post was at 05:01 PM ----------

I have battery stats pro installed but its seemingly useless. It doesnt really tell me anything that I dont already know. Ive used other battery stats programs as well and they all typically just tell me the same stuff that the stock battery stats does.
[Galaxy S III General] DroidZombie:
There is something triggering a wakelock on your phone then. Android OS shouldn't use that much. Have a look at your phones wakelock log.

I just read something on the d2ATT S3 forums about rebooting while charging. Apparently, on some phones this causes a permanent wakelock that requires a reboot while not charging to clear.
[Galaxy S III General] Tengis:
I unplugged my phone this morning about 7 hours ago. It is now at 45%.

Under Kernal Wakelock on BetterBatteryStats Ive got:

"deleted_wake_locks" at the top showing an all blue bar, 8.4%, 6h 8m 13s

"mdm_hsic_pm0" showing all blue bar, 16.8%, 51m

Under Partial Wakelocks Ive got nothing significant:

AudioOut_2 all blue with 2m 38s

Download manager with 1m 43s

Under process Ive got:

Kworder/0:1 through 0:3 all showing nothing but red. Range from 2m 38s to 1m 33s.

CPU state is all deep sleep except for the tiny bit Ive used the phone.
[Galaxy S III General] JarodCB:
Sorry for the late answer!

Thank you, kizuki.buy, for the very good explanation. It seems like something device related? I am glad that you have much experience with this problem.

The best battery life I had was with the stock rom and no root. I used it for quite some time and didn't have problems. Though since the problems appeared I didn't go back to stock. If by now debloated rooted stock are an option, maybe I will try. I can't really live without root...

I am still running the 8.07 Nightly CM and my battery life is still bad where it was okay before. It got really ridiculous yesterday where my screen was turned off and the phone plugged in to charge and the battery still drained. I took a look at the statistic. It charged normally from like 50 to 53, and then plunged back to like 43 while still charging with screen off. Then I charged it shortly using my portable charger while I was driving and unplugged it for a moment, then again and it went from 58 to 92 in an hour or so... (i wanted to upload a screenshot but it didn't work...)

I know that smartphones use power but I can't even use it however I want at home...

Well I will monitor this and if anything comes to light I will let you know.
[Galaxy S III General] DroidZombie:
Start a log for when you charge your phone.

Write in when you plug it in

What % it was at

Where you plugged it in

Then record the battery level every 20 minutes.

If it is really screwy take your phone in and get the battery replaced. When they ask why show them the log.

If the problem persists get your phone replaced.

BBS SHENDU ROMs

Are the ROMs present at BBS Shendu meant for SC-03E? I went to Samsung i9305 SC-03E JAP forum section on bbs shendu. This forum was meant for SC-03E. I downloaded the ROM mentioned on the site for International Edition Users. Its [Android 4.2] [MIUI][4.2.2]MIUI V5 3.8.23 ROM. I was previously runnning CM10.1.

Luckily i had made a nanodroid backup of my current ROM. I placed the ROM in my external sd card, wiped cache and partition, flashed the new ROM. When i tried to boot into the new ROM, the screen flickered and went blue and then black. No idea of what was happening. I rebooted to CWM and restored my backup.

Can somebody tell me whether that ROM is for SC-03E?

Since there is no procedure mentioned for flashing the ROM, did i follow the right one?

If the ROM was meant for my phone and i flashed it correctly, what was going on when i tried to boot the phone?

Sorry. I can't post links as my posts are less than 10.
[Galaxy S III General] IparryU:
I generally try to avoid any Chinese sites for Japanese phones... purely cause i dont want to brick my phone because i could not read their instructions.

I have had the same issue before when converting the i9305 roms and just reverted back to my nandroid backup. it would probably be best if you just find the xda thread for that specific rom and do everything from scratch IMO.
[Galaxy S III General] DroidZombie:
I never flash things cooked by someone I don't trust. Meaning, I flash things I cooked. Porting is not trivial, you could hard brick your phone. If you want miui cook it yourself using the files from kbc developers and my instructions.

[ROM][Unofficial][Carbon][4.2.2] for NTT Docomo SC-03E

CarbonROM is based on Android Open-Source projects. It takes it’s code mainly from CyanogenMOD and incorporates it under a graceful User Interface.

Warning

This post is meant for NTT Docomo SC-03E. I have tested this ROM on my SC-03E, but i don't take any responsibility for any damage to your phone. You will be flashing at your own risk. Please make sure that your are well informed about flashing a custom ROM. If you have any doubts, do ask before trying it.

Recommendation

It is recommended that you make a nandroid backup of your existing ROM and all data before flashing this ROM. If something goes wrong, you can revert back to your existing setup using your nandroid backup.

Note

The original Carbon ROM for GT-i9305 was available here. I converted it for SC-03E using Japanised ROM Tool.

Carbon ROM Features and Details

Here is a quick Carbon 4.2.2 Review - Youtube.

Requirements

Its flash method is same as that for CM10.1 JP Remix for SC-03E posted here. If you are on stock firmware or recovery, follow steps 1 to 3, 4( if you want Osaifu Keitai/Felica), and 5 (to flash CWM,) on the CM10.1 post to get your phone rooted and CWM installed.

Procedure

1. Download CARBON-JB-v1.8-i9305-for-sc03e ROM and gapps and put them on your SD card.

CARBON-JB-v1.8-i9305-for-sc03e

gapps-jb-20130301-signed

Also download the following file to remove the Japanese girl picture which appears on boot screen.

SC03E-JB-KBC-20130519#8-AOSP-boot-signed

2. Reboot into CWM (hold volume up + power button + home) and install the ROM:

-Wipe cache and dalvik

-Wipe Data/Factory Reset/System

-Install CARBON-JB-v1.8-i9305-for-sc03e

-Install gapps-jb-20130301-signed

-Flash C03E-JB-KBC-20130519#8-AOSP-boot-signed

-Reboot

3. You are now running Carbon ROM 4.2.2. Enjoy.

4. Apollo Music Player is missing in the carbon ROM. Download the apk and install it.

Apollo Music Player
[Galaxy S III General] DroidZombie:
Thanks for the splash anim zip. Always ment to go hunting for it just never got to it.

A note about apps. You can add any apps you want to in the cooker. Just browse through the directories to find where the other apk files are and paste the one you want in. I don't remember the location off the top of my head.

And carbon is an awesome rom. I put v1.8 on my wife's alpha and I have the latest 4.3 nightly on my sc-06d.
[Galaxy S III General] majidkhan:
Thank you for the guidance. It was my first ROM. I didn't know about the inclusion of gapps or any other apps in a custom ROM. I had once read about the licensing issues of gapps and didn't bother about them later on. I will give it a try next time.
[Galaxy S III General] DroidZombie:
Don't bother putting gapps into it. I'm talking about apps that you don't have a batch install package for. Or things you want installed in /system not /data

Thanks for keeping my phone entertaining for me! I am fairly new to the custom rom thing and have an issue on this Carbon rom. The volume is extremely low. How do I go about fixing it?

The tethering problem with the stock rom is kinda normal since the apk used for the tehering mode is programmed only to work with docomo rom.

But there is a solution listed in this forum which link to another one with an app to download... sorry i'm busy for know to link the post about it but i will as soon as i have time.
[Galaxy S III General] davidcsv:
This video demonstrates how the toggle works.

The video shows the toggle on the Korean variant of the S3 (SHV-E210K), and in this video, the device has the latest version of the mechanism (animation is different compared to what's in the SC-03E version).

I am wondering, when you guys hit the three button combo, is it the (filler/temp) boot animation you see which the toggle mechanism uses as a visual indicator, or does your phone actually reboot instantly?
[Galaxy S III General] JarodCB:
Alright, thank you! I checked it out, and its exactly what I have been doing. I noticed that in the video you force close the Apps that need root, so I thought maybe that was the problem. I closed all the Apps and tried again, still no good! But at least I know I am not doing anything wrong as far as the three button combo is concerned.

In my case, as soon as I hit the three button combo, it instantly reboots. The screen goes black, the docomo logo, xi and Samsung logo appear and then I have to input my SIM card pin code.

Also I forgot to mention before, but yes I had USB Debugging checked. I will try to flash again and if anything happens I will report back.

I don't know if its just me or if more people experience the same problems. But thanks anyway, I'm glad you guys don't leave is hanging!

If you have any other suggestions, I will happily try it out! I want to be king of my castle (phone) again.

I will prepare a new image with the latest script and components of the toggle switch. I'll post an update here as soon as it is ready for download.
