Ok I think I got it...here's what's going on (I had the insane battery drain myself) - the ROM on it's own seems to work just fine...no glitches or anything like that (other than the wallpaper...and the missing things from the features list).

There is an app that causes the battery drain, and

I personally suspect it's root-related

. I've been testing mine and so far, 6 hours, 5% drain. now I'm starting to install and leave for testing one-by-one every app I usually use to see which will cause the issue, but I'll leave the SuperSU (rooting) for last.

I recommend you backup your contacts and stuff, format the USB storage, make sure your phone is unrooted (there's a permanent unroot option in SuperSU, and run the Busybox complete-removal thing someone posted here in XDA if you had busybox), factory-reset it in the recovery menu, then remove the battery while it's re-booting, then flash again the ROM with Odin. In short - return it to fully unrooted, then flash the ROM. That'll get you to the same spot I am now (no battery drain issues).

I'll report here any findings with apps causing trouble as I go along with the tests, currently testing Avast! Mobile Security.

If you want to test yourself: install something, then leave the phone for about 2 hours with WiFi/3G/GPS off, then check the battery stats and see if the phone was awake when the screen was turned off. If it wasn't, then the app in question is not causing issues.

After flashing XWLS8, then did a factory reset and restart my phone, i think XWLS8 is bug free 4.1.2 rom, compare with leak version, lagging on messaging had gone in XWLS8, battery is good enough for me, it drain 8% after 8 hours sleep with wifi, data off and power saving mode enabled.

The wallpapers problems is not a bug i think, it's a diffirent point between nature ux and touchwiz ux. For example, in galaxy s3, you don't have a scrolling wallpapers, but in Xperia arc s, you always have to use scrolling wallpapers and 5 home screen

XWLS8 is completely smooth and stable rom, i recomment all you to flash and feel the diffirent comes from android 4.1.2 Jelly Bean.
[Galaxy S II General] khaled_7:
is there any difference between the LS8 and LSJ base ??

anybody noticed anything ?
[Galaxy S II General] CrisR82:
But here it's not vertical-still, and it's not horizontal scroll (despite looking like it)...the wallpaper thing IS a bug obviously. And add the missing features to the list (also, no gap-less playback for music, which I was really looking forward to)...persona thoughts - it's pretty usable, way better than the leak, but it's not complete, it's clearly rushed (didn't expect anything better from Spain)...I hope to see Poland, Sweden or Germany's version, those are usually the best.
[Galaxy S II General] GuardianFlash:
Please can someone tell me will this update work for my i9100M from Bell Canada. Please!
[Galaxy S II General] levankd:
So do I, waiting for more offical releases with full features. But I'm not sure about fixing wallpapers features.., I think Wallpapers scrolling feature has been replaced by some effect in Nature UX like home scrolling effect. :rolleyes:
[Galaxy S II General] CrisR82:
So far after over-night testing I found these things:

- The Email account (for the Samsung Email app) doesn't not work, or at lest it doesn't work with Gmail (wrong email or password error).

- Skype has a serious issue preventing it from working (only once out of 10 tries it actually started and connected), haven't tested other IM apps yet. NOTE: Skype is actually working fine on all other JB devices, so this is still relevant to the ROM in question.

- Battery life is normal (difference between ICS would be few minutes, definitely no noticeable difference).

- No Social Hub available for some reason...despite the SNS service still being present.

- Dropbox will not give you 50GB space even if you install it separately.

- Gapless music playback not present.

- Camera video lag not present.

- Samsung Video Hub gives you a free movie coupon on first use (buy any movie, SD or HD for free, supports downloading, but no language selection).

Haven't rooted the phone yet, but so far it works as it should.

i think there is a bug in latest rom that is data cannot be wiped i tried many times...
[Galaxy S II General] CrisR82:
Worked fine on my side yesterday using the stock Recovery Mode.
[Galaxy S II General] mbevc1:
So battery is the same as latest ICS 4.0.4 Ukraine? I was thinking to give it a go tomorrow with full recharge... So as far as I read posts it looks like with vanila stock there is no known issues? Thanks !

Re: [Stock Official Firmwares] I9100XWLS8 (4.1.2) - Spain (FOP) [23-01-13]

Yup, no problems with wiping data
[Galaxy S II General] CrisR82:
I've been really busy trying to figure out what caused the huge drain I had before, but so far with "intensive" use it seems to be the same (hard to tell obviously).

With 4.0.4 I was able to get roughly 6 full days+ battery life while using only the alarm clock and checking on the weather once or twice per day...as soon as I'm done testing and installing my stuff, I'll do that test with this ROM aswell and see for sure.
[Galaxy S II General] iozzo:
Strange, both skype and the email app (I did try both the gmail and Samsung emaill apps) are working fine for me. I have been using both since yesterday and had zero issues whatsoever.

As for DropBox, I didn't create a new account as I first booted JB believing my older one would have been upgraded. Nope it didn't. Hence I went into the settings of my dropbox account to "Disconnect the device from DropBox" cause I wanted to create a new account. After few second I received a mail from DropBox telling me that my old account was upgrated to 52GB ( I had 2 giga already). Have a try

I am rooted and did a clean install wiping everything before.

Is there a fix for the WI-fi problem? That is the only problem that I found on this firmware, and is kinda annoying, because sometimes turning wi-fi on/off doesnt solve the problem.
[Galaxy S II General] Stileth:
What wifi problem?
[Galaxy S II General] lfabresm:
After a overnight experience with this JB firmware, almost everything working except a few things:

- Vimeo player just go black (I'm figure out if it's something related to restoration from Titanium Backup)

- No problems with Skype as other user reported.

- I still can't found the "auto-replace words" function for predictive text on samsung keyboard.

- The battery seems to be OK, but the "Media" process take a significant amount of charge after every restart :( (my actual statics after power up this morning >> 1h 24m of run, Battery 82%, Media 46%, Display 36%)

- I feel this firmware takes more RAM than 4.0.4, average use is at 632MB of 826MB :eek:

- At the beginnig, Apex Launcher shows some lags during screen swipe, total used RAM was over 730MB. I go to Titanium Backup and freeze some Samsung apps and gets a little bit better, as I mentioned before.

Let's see how will be during this day.

Cheers!

Maybe it's because what amount of media files we have on sdcard. I got this battery issue, but I have a lot of pictures, videos and music on internal and external (16gb) sd card.
[Galaxy S II General] vibecatalin:
If you are connected to a Wi-fi hotspot when you come out of the range of that, then come back in (not necessarily immediately ) the Wi-fi speed drops very much, I''ve done some testing.
[Galaxy S II General] lfabresm:
Just install Apex launcher or something similar. You will got scrolling wallpapers and rotation.

Re: [Stock Official Firmwares] I9100XWLS8 (4.1.2) - Spain (FOP) [23-01-13]

I flashed xwls8 with pc odin and rooted with siyah 6b4 with full wipe.Three programs had problems for me. titanium backup, super backup which were in ext SD card were read only so I can't done any backup for it. Also i can't deleted away the titaniunn and super backup folder in the ext SD card. But I can backup in the internal SD card. Super manager was not able to save favorite folder. Beside the above problems xwls8 was very smooth and fast.

Not happen to me on xxlsj. Very weir to me and this happened after I upgraded from xxlsj to xwls8.

I will reflashed xwls8 as soon as possible and reported back.

there are 2 new firmware update (CHZ-CHN) from samsung update
[Galaxy S II General] Re-FleX_NL:
Please everybody that have battery problems with this firmware...

Its Stock firmware so if you have battery issues it has nothing to do with this firmware! I installed it 2 days ago and it has really good battery life... the only thing that sucks the power out of my battery is the fact that i cant stop touching my screen now!

plz if you have problems try to re-callibrate the battery by downloading battery callibration out of play store (you need root!)

You dont have root?

download this file (with thx 2 chainfire) (i upload it with this post):

Root_SuperSU.0.96-Busybox.1.20.2-S2-signed

put in on ure device sd_card

and just flash it with stock revovery

steps to do with callibration:

1. Charge ure phone till it has 100% full charge of battery! make sure it has 100%!!! Turn your device off and turn it on again to check it is really 100%.

2. Delete batterystats.bin by using this app.

3. Make sure you fully unload the device to 0% battery!!!!! important step!

4. Fully charge it to 100% without interrupt!!! touching important step to!

5.If this doenst work i really think you have to reflash the rom (i did it from stock 4.0.4)

6. Enjoy! and dont forget to say Thanks!

[Galaxy S II General] Re-FleX_NL:
4 hours on screen time... i dont think thats bad... how is ure screen settings....
[Galaxy S II General] mpjoe2000:
No matter what you do you will not get good battery life with the screen on compare to Jelly Bam or others good roms based on CM10.x with auto brightness enabled, sorry but that is a true fact. But, we have to be conscious that WLS8 rom have a higher values on auto brightness, so the screen will drain battery faster.

Deep sleep is working good.
[Galaxy S II General] Re-FleX_NL:
This is for users with HIGH battery drain... i know this what u say just turn auto adjust off and select a low screen brightness to save batt....
[Galaxy S II General] Tungstwenty:
I would make yet another suggestion, even though I haven't installed JB yet:

Any of you with battery drain, please check if MediaScanner is not the reason for it. I have had several occurrences of this issue in the past and after checking the reason for heat + drain I finally noticed that it was usually the media scanner. Stopping it on the task manager usually solved it, i.e. after rebooting it didn't hang.

Since even with a wipe the contents of the internal sdcard will be different for each of us, this might be an explanation why some of the users have battery issues while others don't.

Of course, properly using BBS would pinpoint this if it was indeed the reason (low deep sleep % + either PWL related with media or high CPU usage from that process)

Clean install...

I've looked around, but I can't find the answer to this.

What is the process for flashing this ROM as a clean install - ending up as though it just came out of the box.

I've flashed so many ROMs and Kernels over time that my install is a real mishmash of things. I wouldn't mind dumping everything and starting "Fresh", re-rooting, and going from there. How do I do that safely?

[Galaxy S II General] CrisR82:
You're wrong actually, that won't put it in "stock mode", that'll just put the settings, data from the previous ROM is left behind.

The full procedure:

- backup your data (Kies should be enough...or GO Backup)

- format the USB storage (from settings - memory)

- [OPTIONAL, for rooted only] if you're using SuperSU - open it and use the "full unroot" option...for other root apps/methods, no clue...but there's a full-Busybox removal script somewhere here on XDA

- turn off the phone and enter Recovery Mode (up-volume+power+home keys)

- whipe Data and Cache

- restart the phone and take out the battery before it turns back on

- go in Download Mode (down-volume+power+home keys)

- connect to the PC via USB and flash the ROM with Odin

That's how you get complete stock without left-over settings/files.

I had XXLSJ ROM before and I flashed XWLS8 non-wipe.

When you wipe data / do a factory reset, then you will have to choose your language as first selection in setup wizard.
