So I am currently running Carbon Rom on my phone. Whenever I lock my phone and I unlock it, in the notifications, it says that its preparing my storage everytime. But now, it says that my SD card is blank or unsupported but it works perfectly fine my computer. I've had this problem for about 2 months now. I've already tried changing the rom and clearing the cache. Also, I tried to take out my SD and put it back in but not luck. So please help on that. Also, I was just wondering, so as you already know, I'm running the Carbon Rom on my phone. It's a great rom but the battery life sucks. I would like a rom similar to Carbon that is 4.3 or 4.2 that is very smooth and also has great battery life. I tend to use my phone a lot, and I know that battery life on androids suck but some other roms had much better battery life on them, but I didn't really like them much. Thanks for all your help!
Played with Carbon and other roms, none are close to the battery life of Shostock roms (I've run 2,3, currently 4). And SS is about tops for smoothness and stability. Some of these roms are so much worse on battery life that it's pointless to use them if you actually "use" your phone throughout the day, unless you have it plugged in everywhere you go.
Far as the SD card not sure there, did it do it on stock or any other rom?

So I switched to Shostock 4.0. It's pretty smooth but my battery life isn't so hot. Maybe I just have to give it a day or two. And the problem isn't happening now. But usually, the problems comes after about a week of using a rom. Also, sometimes, there's random reboots.

I do know Sho roms are always tops for battery life of the i777 roms. Never had random reboots or anything on any of the Sho versions. There could be something else wrong with the phone, rogue apps, something killing on gps power, battery gone bad. These phones are two years old now, and a lot of people have had the battery itself go bad before that time, I just replaced mine like a month ago. Just randomly started getting worse and worse phone life over the past couple months.
I keep GPS on all the time, and sync etc, only thing I adjust is WiFi set to stay on in sleep mode only when plugged in (Android has always had that battery sapping wifi bug). You should try running stock though for maybe a week or two and see if the issues occur, if they do, it could be hardware issue.

Random reboots are usually due to a kernel issue, rather than a ROM issue.

Everyone will get different results, period. I get great battery life with Carbon, drop maybe 40-50% over the course of a day. Much of the building I work in, is a black hole when it comes to cell coverage, so I'm happy with my results.

So your not using your phone since there's no cell coverage? That's the thing I'm on my phone all day for work/personal, ton of calls, emails, text, browsing etc, used a bunch of roms but always come back to Sho on the i777. Have two employees with i777s running Sho too, same results, none of the roms they used had the standby and in use efficiency. Not to say the roms are bad, Carbon is cool, just wish they all had better life.
I will say if you notice a big difference like I did over last few months, time to replace the battery. Sammy shipped crap batteries in these phones, and it's a known issue that majority fail before two years are up. Mine did and my employees did lol

Yeah, so, I switched back to jeboo kernel but the battery life sucks! I'm going to wait a day or two and see if the problem goes away. Also, on this rom, I also sometimes when I unlock my phone, it always says preparing SD card. Its annoying.

If your having these same issues across different roms like you are, run stock for like a week at least and see what happens. Not sure what you mean by switched to Jeboo as Sho4 comes stock with Jeboo tweaked for it.
Also if battery life is sucking that bad especially on roms known for battery life, 99% sure its time to replace the battery. Samsung shipped crap batteries in this phone that frequently die between 1.5-2 years. I've replaced mine, two employees have, few other i777 friends have etc.
How long have you been owned the phone's battery? The above poster mentioned battery usage which (if you're still rocking a day 1 release S2) the battery is at the 2 year mark. Might be time to get a replacement battery.

First time poster, long time lurker...
As far as I can find, I have not seen this issue come up for anyone else. I recently jumped in with the temp root to clean up the bloat and to de-sense. Process went great and everything that I attempted to freeze is froze.
To my dismay, the last two days (since I performed the clean up) my battery life has taken a severe turn for the worse. With screen off I'm losing about 10% an hour, which is way more than before. I used to easily get a day at the office, but now a morning is a lot to ask.
I've checked the usual suspects, and have gone as far as uninstalling any new apps that I've installed since the root. All to no improvement.
I suppose my next step is to re-bloat to see if that brings me back to where I was. But before I go that far, has anyone seen or heard of this problem? If I'm the only one, I suspect my cause and effect is off. I fully expected this to help the ol' battery... But its been the opposite.
I have the exact same problem, I am going to factory reset mine as soon as I have time to set everything up again.
My battery life has literally dropped in half.
~John
Bummer, exactly what I was trying to avoid. Oh well, that's the risk we take I guess.
With all the memory and speed this phone has there is no reason to freeze anything. I can live with bloatware until I get s-off.
When you go freezing apps you alter the way the phone operates. You could have frozen something that the system needed to operate using less
Power. Now your phone works harder and uses a lot more power. This phone is faster and smoother than any rooted phone I ever owned.

True statement. One of the reasons I have not updated my temp root script to include de-sensing is because every time I try it it runs like crap. Seems like it just struggles looking for things the framework expects to be there.
Ah, the voice of reason! You are right, I was tottaly content until I started f'n around with the insides. Ill unfreeze it all tonight and keep my fingers crossed that I don't end up needing to reset.

Agreed... This phone is a beast with an OEM extended battery. I used %40 in 14 hours with my standard usage, which includes about 30 mins worth of calls, receiving emails and texting.

+1, i'm very satisfied with the stock battery on daily use.
When I travel, I throw in the extended battery and I'm watching an entire season of Arrested Development, no problem :x
I haven't desensed, and I only froze some of the bloatware, like the friendstream, nfl mobile...etc. that were in the app's folder, just to keep it clean, but I've learned I just crowd it up again as soon as I start downloading apps No task killers either, just use the one that shipped with it to kill some lingering apps now and then.

I was actually using your tool... appreciate your work on that, it's flawless as far as I can tell. Was going to thank you over on the development board but being an XDA noob I was not allowed!
I thawed everything out and will see tomorrow if I'm back to where I should be. If so, I may give your recommended list a try and see what that brings. I was really liking not having to see all that crapware everywhere I turned.
That is the reason I didn't use the de-sense option. I only froze some of the bloat that i really didn't use. I was afraid that if I de-sensed, it would cause more problems than it fixed.
I started a thread where I gave a long list of freezeable apps, it's linked in one of the stickies in the dev section, and I have left them all frozen. Something like 30 apps frozen. I have NOT de sensed though. I lose 1-2% an hour while idle, though the first 10% from 100 to 90 lasts much longer (complete opposite of my old Dinc which would drop the first 10% in ten mins!)
Well, I bit the bullet and factory reset tonight. We'll see how my battery fares tomorrow.
I had ADWLauncher installed before with a theme and custom icons etc. I left all that out this time.
I do like Sense quite a bit (I love the widgets) so I'm sticking with that for now.
I have two extended batteries I bought with the phone and originally my battery life was outstanding. I could stream audio all day at work (switching between iheart and Sirius) and still have battery life on my way home.
This is outstanding, no other phone I have owned could do that. Lately, my battery life is in the toilet however. I killed an extended battery in a half a day.

definitley looking forward to hearing about the results to the factory reset. i haven't had great battery life but i've also temp root and cleaned pretty soon after getting the phone, so i don't have too much to compare to.

Let us know how it goes, I'll do the same. I used my freeze script to thaw it all out... hopefully I can leave this thing on my desk for a couple hours tomorrow so I can get some good data on idle usage. Fingers crossed it goes back to the way it was.
I have actually been using Go since day one. I never really tried sense, but it drives me nuts not having a dock bar... I think we can all admit the bar at the bottom is a waste of space. Anyway, I played with it a little tonight and it seems super smooth with good looking widgets (as you mentioned). I may have to get it all set up sometime and see if I can get over my dock bar hang-up.
I had the same battery problem as you and I have yet to even temp root my phone(I run Windows 8 Dev Preview, drivers are unsupported). I don't even play games on my phone and had the same issue. It isn't a root/bloat/de-sense issue.
AtL, that battery chart looks painful. Read the issues list if you haven't already... Some folks have reported battery life like that and ended up trading in and getting one that behaved a little better.
As for my issue, after half a day it looks like thawing everything out was the ticket. This chart vs the one in the OP clearly shows a much slower idle draw. I think I'm back to only charging once a day.
So let that be a lesson to everyone... Be careful of what you think you don't want.
The factory reset seems to have helped some, but it's still not back to where it used too be. I have been streaming iheart all day on 4g using an extended battery. I got probably 6 hours out of the 1st battery & I'm down to 80% on the 2nd battery now.
I think the 4g network may be partly to blame in that I think my higher battery useage started almost exactly when the national 4g outage occured.

I have been here a while bud. I was just posting to show that I had the same issue while NOT using Temp Root or anything you had used in your experience of the problem. This has only happened to me 1 time.
Debloated with no issues
If you know what your doing and have exp with this debloating / desensing will have only positives on your battery. Im pretty sure that horrid battery life had nothing to do with debloating. And as the OP stated it only proved mild imrpovements aftyer hard reset. Unlikely debloat caused that.
Took phone off charger this AM
would explain why when I had the rezound, the battery life started out great, then get beyond terrible.
I installed the Resurrection 1.0 rom yesterday, but 30 mins web browsing this morning dropped the battery to 80%!
Which ICS SGS2 rom gets the best battery life?
It's best you try them for yourself, Just keep testing until you find one that is suitable. I personally, keep changing between CM9, WanamLite, Foxhound, Resurrection (Maybe you didn't install it correctly? Worked fine for me).
So far WanamLite is just right for me (Different ROMs have different advantages ) It's also Quite good on Battery Life.
Definitely installed ok, not much you can do wrong installing it tbh
Never heard of Wanamlite or Foxhound. Had been using Checkrom 2.3.6, but fancied trying out ICS to see what it was like.
After flashing a new ROM quite often you need to drain the battery completely and charge it a couple of times before you really get the best battery life from it.
I'd drained it last night and charged it fully, maybe I'll try it a couple more times before changing again.
Mind you shouldn't be hard draining it at this rate

80% Battery consumption after browsing for 30min doesn't sound right, out of curiosity, did you notice a sudden drop in battery life all at once or was it gradual throughout when browsing, Just asking coz I know some ROMs have an ICS bug where the battery would register wrong % values all of a sudden esp after taking it off charge, the quick fix for this is to take out the battery for about 10sec + then reinsert it.
It was gradual throughout the 30 minutes, but between stopping browsing and putting the phone away and getting into work it dropped another 8% or so down to 72% with no activity.
Might just be calibration errors. Hope so, it's a nice rom, very smooth and stable (the qualities I look for most tbh).

Btw you can find a list of SGS 2 ROMs over here http://www.galaxys2roms.com/

Just try them until you find one that meets your needs.

What exactly is the process kworker, and what does it do?
On two different custom roms (Shostock and Phone Bricker - multiple versions, even with latest v2.7), this process is KILLING my battery, to the point of 25-30% overnight with ZERO usage.... sending 1-2 text msgs in a row, I could watch the percentage drop 1-2% in that short time.
On STOCK rom with stock kernel, or Cherry Picker or Siyah kernels, I do NOT have this problem and I can get 24-36 hours of unplugged time with at least 12 of those hours being heavy to moderate usage... I can sit and post in Facebook for a solid hour and only go through 2-3%... but if I go custom, I'd lose 3-4x that amount of power.
I'm just wondering what I'm missing....
I know its with the kernel. It used to be a problem with Linux, but updates fixed it. I have a few kworker process that I to would like to get rid of on my phone... though, they dont wear down my battery like yours! Mine keep my phone awake for a while... thats about it. I am going to watch this thread closely to see what people have to say about FIXING this issue...
I'd appreciate that... I don't like being restricted to a stock rom just to get decent battery life.
Today I installed Phone Bricker v2.7 after a complete reset... simply loaded the rom, didn't sign in with Google, simply loaded an app to monitor usage and took a nap... in not even 90 mins, it'd already dropped to 92% from a full charge with no usage.
I'm seeing this type of behavior from both Phone Bricker and ShoSTOCK.
Am I doing something wrong?
Gotta give it a couple days to settle. Battery percentages will never report correctly for the first couple days after flashing a new kernel (and both of those ROMs include a kernel, I believe). It's been posted a couple times throughout this forum, but I know it's a little hard to find sometimes, so I'll cut you a break. See here for a recent example.
After a few days, then you can check to see if kworker is still killing your battery, and you'll have a much better idea.
Well, I'd run Phone Bricker for roughly 2 weeks, dating back to v2.5, and tried sticking it out through the "settle" time on v2.7 as well, but performance never improved.
Also worked with ShoSTOCK, also well over 2 weeks with no negligible improvement... my battery just kept being drained and it's taken me the better part of a month to narrow down this one process that is the culprit.

Live wallpapers, even if screen is off, will drain your battery like crazy.
Checked Facebook on 100% charge, was on for maybe 10minutes. Turned off screen for a little over an hour. When I checked my phone I had 90% battery. 1%/min drain? Hmm... I turned off tgeclive wallpaper and my battery is now at 83% after 4 more hours and some mild/moderate use of the phone.
Might not be news, but a great tip. Didn't have this issue as bad on stock GB, but I still refuse to run live wallpapers after seeing that happen.

Not all LWPs do this...only the badly coded ones.
I've never used LWP because I'd always heard/assumed it was a battery kill - can you recommend some that you know to be solid?
Thanks for all the feedback so far gang.... as for this stock rom, as we sit, it's at 16 hours off charge and I'm still at 66% with moderate usage, and that's just beautiful, I just wish I could achieve the same with aftermarket roms as well.
Anyone???
I'd went back to stock, and it was working AWESOME for about 2 weeks as far as battery life goes, but suddenly the phone would lose it's data connection, requiring a reboot. After the reboot the phone had no signal bars, just a 0 with a line through it.... 3-4 restarts later, 3G + data would eventually come back, but data would last sometimes 5 minutes, or 5 hours before stopping.
I was out of town for 3 days, just got back, and while on the road I lost signal so much that I had no choice but to pull over, fire up the laptop and download a new rom... I did a full wipe, factory reset/data, wipe cache and dalvik and was using Shostock v3.0. I had horrid battery time due to this and I feel after 3 days of moderate usage, it's had time to "settle" with no changes. Had ZERO data problems, but horrid battery time due to kworker.
Last night (roughly 12 hours ago) I installed Serindipity 9, and already right out of the gate, showing kworker just blasting the battery... this process is haunting me with the roms I'm installing...
I installed a new SD card for troubleshooting purposes... no affect.

don't worry you are not alone. seems like this kworker issue is going around and making lot of people crazy including me.
I tried removing all application which use some kind of timer. Still no go, the kworker comes back to haunt me too all roms - aokp, phone bricker, serendipity, even hell raised one
This issue has just about killed my ability to use any custom rom on this phone.... surely I can't be the only one affected???
I see in another post that this seems to be a hot topic, but then again there are so many others that seem to be flying with no problem....

At this point - I'd LOVE to know. Some are getting great usage with custom roms, and I'm still stuck on stock because ANY other rom kills my battery in less than a day... drops 25-30% overnight unused.

I apologize in advance, but could you provide more specifics on Watchdog? What version, author, etc? I'm reluctantly am gonna reinstall shostock2 v3.0.4, monitor and report back - any help you could provide on watchdog would be great! Thanks!
I tried Vigor360, and though I hate Sense, it was.. okay...except battery life was worse than on my Thunderbolt. I've tried flashing different kernels but more problems usually arrise out of the blue and I have NO CLUE which kernels are actually good , good as in they actually male an effort to improve the battery life. I'm currently on a CM9 ROM and holy hell! The keyboard lags and battery life is ATROCIOUS ! I haven't even hardly installed any apps!
I tried Newt's One XXX, v5.1.1 but couldn't stand the minor bugs, but I assume battery life on that ROM is way worse than on Vigor360 (since usually, the higher the version of Sense, the worse it is on the battery) when I had a galaxy Nexus, the picture quality was a joke, but I made it well through the day with it! I'm not getting an extended battery. The phone is thick enough -.-
My current usage is about 7 hours,an hour and a half of screen time, battery is at 7%. I can sort of stand sense 3.6 so long as it isn't theme. What ROM/kernel combo do you guys use to get through the day, or did I make a mistake getting this phone? (No offense)

going to need some things from you:
1. are you s-on or off
2. what firmware are you on
3. do you like sense or aosp more
edit: 7 and 1/2 hours screen time. that is awesome for the REZ. the HD screen is what kills the battery the most. if you can get 7 hours then bravo.
He said he is averaging 7hrs of use with 1.5hrs screen time which is pretty bad. Believe it or not, newts one xxx has probably the best battery life for the rez. I can easily get 14hrs with 3hrs screen time with stock battery. Yesterday I got 17 hrs with 5.5hrs screen time on extended battery. That is probably the best Rom atm and sense 4+ is much more appealing to the eye. All I can say is if you don't like sense, you bought the wrong phone. People will forget about this phone before aosp/aokp is perfected, even though they are making great progress. I can never get any kernels to work right either. Leaving stock kernels is usually best. As with any android phone, you have to work for battery life

Wow!! The big reason I have this phone is.. well..
Had a Nexus, broke it and sold it for $75, relative let me use an iPhone 4... I lasted a week before caving and bought a Thunderbolt for $90.
I couldn't stand the ancient android OS and the phone was having random data drops, so I got Verizon to replace it with another thunderbolt. The replacement had the same issue + the vibrate motor decided when and when not to work. The guy on the phone was like "well, since you've had several replacements of this phone, we're gonna see about sending g you a different phone to resolve your issues once and for all, but the phone you receive won't come with a battery cover or battery." I told him I had a battery cover and battery for a Rezound and asked if that could be sent to me, he said "sure, we should be able to do that."
This phone killed my 32GB microSD card :'(
I have S-OFF. I prefer AOSP, but they seem get get home horrendous battery life.

When asking for help you usually shouldn't trash every kernel/rom made available to us by our hard working devs. Also, your theory on the sense number being higher = higher battery usage is way false. Sense 4 & sense 4.1 were actually designed to decrease battery usage and lag so I would stick with one of those. Also, try underclocking your cpu and changing governors.

People need to stop judging battery life based on screen-on time and hours of use. It varies per person depending on how many accs/apps are syncing. I am tired of all this "better battery" and comparing usage time. If you want more battery, stop syncing on all apps/account. I wish people would stop posting screenshots of their usage. It just means they don't use their phone as much in terms of accs and apps running. Stock rom/kernel best for stability.

It might vary somewhat, but screen-on time and total time are still good yardstick level indicators of battery charge longevity. It's not like when you sync your google account your battery only lasts 1/3 as long - it's maybe a 10% difference, depending on your signal strength, if you're on wifi, etc.

Try reformatting the sd card on your computer via a card reader.
Rage ROM 1.9.1 is a good ROM, nice and smooth. I got about 2 and a half hours of screen on time with that ROM and Snuzzos Funky Kernel. Very nice combination.
If you want to be real fancy you can build a CM10 ROM. There's a guide for it in the Dev section. (Well, the guide is to make CM9, but it's easy to modify the commands to make it build CM10 instead). I get about 3 hours and 15 mins of screen on time on average with the stock battery, no kernel modifications or anything fancy. Brightness is at 25%. I ran it with brightness on 100% for a day and got about 2 hrs and 15 mins of screen on time.

As much as you dislike this method of determining battery life, it is really the only way to gauge battery life on a forum. You are right that it also depends on apps syncing and such but a Rom that can get 12hrs with 3hrs screen time is more battery friendly than a Rom that can do that same12hrs but with 1.5hrs screen on time with the same setup and usage.

How much battery account sync uses is dependent on just how popular you are we have push sync. This isn't Android 1.5 wen're talking about. Push sync uses very little battery.
And sure, I could build a CM10 ROM, but won't it basically be useless cause most things will be broken or barely working?
I've been running it as a daily driver since the 12th. It's surprisingly stable. No random FCs or anything. There are some graphical artifacts while watching streaming video like on YouTube and Project Butter isn't working, but it's still pretty smooth. Bluetooth calling isn't working either, but nor is it on AOSP ICS either. That's pretty much it for problems.

how the heck are you guys getting these ridiculous screen on times with the stock battery?? the best ive ever gotten WITH AND EXTENDED BATTERY is like 3hr screen on time and ~13 hours unplugged with countershrikes AOSP and Funky Kernel
and no where near that with my stock battery

I've been wondering that myself lol. I haven't done anything different; same apps, same sync settings, same display brightness, just the ROM + kernel is different. I'm not even undervolted like I was and I'm doing better than before lol... Must be the ROM/stock CM10 kernel I guess.

I have been trying out various 4.4.x ROMs (CM, Resurrection Remix, SlimROM) and had varying levels of success but the one issue that I have had consistently with all of them on my SGS2 is battery. 4.4.x seems to devour my battery no matter which ROM I am using (and the different ROMS are using different kernels usual). CM11 has far and away been the most stable so I have stayed with that but it too as failed to resolve my battery issue. I have never had much luck with battery life before but half a day is ridiculous. I thought about trying a different kernel but not sure that would help as #1 I would think the CM team would know better than I what would be the optimal kernel and #2 I have been trying different kernels anyway when I have been trying different ROMS as I believe the different ROMS have all had different kernels. Has anyone else had this issue? More importantly has anyone had any luck resolving this?
I suggest you to replace your battery. Beaware from cheap ones!!! I have I9100 too, i also try many methods to increase my battery life but i reach maximum 10 hours. Then i buy new batteries. It is not original galaxy s2 batteries but i think better than the original one.(1800mAh buy from ebay) Now i use RR kit kat rom with stock kernel my mobile data is always on and I go to bed at %35 percent of batteries.
1. If your battery is quite old, replace it.
2. Check whether you are having any wakelocks. Does it go to deep sleep?
3. When you say battery life as half a day, what is your actual usage? Screen on time, Wi-Fi, 3g, calls etc?
4. Betterbatterystats and greenify are your friends.

Thanks. My battery is about 2.5 years old, its an Anker battery, 1900mAh that I bought on amazon (I honestly don't know what constitutes "old" for batteries, is 2 1/2 years old?). As for ROMS I was actually running an older version of RR but had serious stability issues (related to sdcard, never was able to resolve it) and battery wasn't great (better than now though) when I upgraded to the newest RR I had some lingering stability issues and battery issues too so just settled on CM11 this time.

I am not totally clear on wakelocks and deep sleep, I have "Battery Stats" installed (guess its not the same as the betterbatteryapp but seems to give some similar info) but its not clear to me how to read it all. In this case it sayd the stat period is 3 hours 8 minutes and out of that it has been in deep sleep 1h 51m and running time 1h 17m and wifi time 1h 25m and my batter is down to 74%, I am assuming that is not normal? In terms of applications the hogs are defintely the two audio apps poweramp and dogcatcher (they are just at the top of the list, the numbers it gives don't really make sense to me)

Well I have a 3 hour idea of my usage above, I don't use 3 g, I have wifi on about a third of the day perhaps, and actualy screen time probably just an hour or two, I do use it quite a bit for podcasts and music though. But I had tried it with my audio apps uninstalled for a few days and it still drained fairly quickly.

If your battery is 2.5 yrs old, that's almost certainly the cause of your issues. Good advice to stick to original Samsung batteries; though there's nothing wrong with the 2000mAh genuine Samsung battery Vs the 1650mAh one - I used one of these for almost two years.

Doh, was hoping I wouldn't have to replace the battery. Actually... that said. Should a 2.5 year old mostly unused 1650mah samsung battery still be good? I think I still have the factory battery around somewhere now that I think about it. When I purchased the Anker battery I seemed to remember it was mainly for price and reputation reasons, not that the Samsung battery had such a bad reputation but the Anker had such a good reputation and a pretty good price.
I will give another battery a try if you say 2.5 years is old, but I do have to admit that the battery drain was not nearly as much of an issue with the older ROM I was using (RR 4.2.x) before, it wasn't stellar but not like this so it seems to me its more than just the batter thats giving me problems here.
Anyway, my phone is still golden other than the battery issues so if i can squeeze another year and a half out of it I'd be a happy camper. Any other thoughts would be welcome (and appreciated!)
Batteries discharge over time if they're stored/not used, ideally you should charge it up to/keep it at around 60-65% every few mths if you're going to store it for that long. If you've not touched it at all in that time, it might not be able to take/hold a charge anymore because that wasn't done.
Only way you're going to find out is if you charge it & use it.
Yeah, if you ended up getting 4 yrs out of a smartphone you'd be rather happy indeed.
If you really want to satisfy yourself as to whether it is indeed the age of the battery you're currently using causing your problems, do a clean install of stock & test that for a week. If it does the same thing with stock, you'll know for definite it is the battery. I'd be very surprised if it isn't though; they're not designed to last much longer than what you've had yours if you're charging/discharging constantly.

Thats a good idea, given what you've said i don't doubt that a large part of my problem is the battery (like I said before, with the older rom it was better but not stellar) do you know where I can find a stock rom nowadays? (sorry on the ROMS page they all seem to be custom roms, or perhaps i missed something?)
Thanks!
Stock roms @ Samfirmware, get one for your carrier/country (not 4.0.4 though, anything else is fine), if there's only 4.0.4 for your carrier/country, any other stock rom will do really -I just tell people to stick to carrier/country in the first instance as these have modems bundled with them that should have been tested by the carrier to give most people on their network good connectivity most of the time.
Or, Wanam has a thread in one of the development sections (I forget which; do a search or have a rummage around) that has CWM flashable stock roms if you'd prefer to do it that way; haven't had a look at the thread for a while so not sure if links are still live, but Wanam is a very active dev & I'd be surprised if he doesn't still have them hosted somewhere.
Does it drain more at a locationw where you use a certain Wifi?
I'm asking cause wlan-rx drains are know Android phones in big open Wifis as the phones get bombarded with signals from other computers/phones and are not filtered and keeps the phone awake.
Easiest way to find out is using Betterbatterystats.
