LA2 multi-csc firmware - read this before flashing - Galaxy S II General

hi all,have downloaded and flashed the LA2 multi-csc firmware and completed a few battery cycles. I can report slightly increased performance from the previous versions, but signal strength is not great. Battery is way worse, I literally have to charge twice a day. Once in the morning and once in the afternoon. for some reason, battery is always drained after a nights sleep, consumed mostly (>90%) by Androis OS. Swipe doesn't work as well either.
What's your experience with LA2 so far?

This rom has the best battery life of any I've used. Its the smoothest I've used, and the best that I've used.
If you are having battery issues may I suggest a full wipe is in order, there's a lot of changes in this rom and some setting from your old firmware may be causing the high OS drain issue as my Android OS usage is around 15-25% most days.

As its a beta test rom not the finished product its not a firmware i would ever use .
For the simple fact test and beta both mean what they say .

It's official if he means XILA2.
@op: either something is wrong with your configuration or you've got some dodgy application eating your megahertz.

@kitch9: my Android OS usage is always at least 60%+ with previous firmware, 25% would be amazing!!!

@JJEgan: It's XILA2 and official.
@Intratech: is there a way to find out what app may be causing this? My phone also gets warm overnight too.

Awful Awful battery life since Darky's ROM

I have always had stock ROMS with my i9000, ending with JS7. I read the battery problems people had and I always counted myself very lucky that my phone had a pretty decent battery life.
Daily I would SMS (a lot), the odd phone call, quick blip on the internet (3g), lots of angry birds and doodle jump! I would get at least a couple of days before it went into the red.
Then I made the big mistake of installing Darky's ROM, it looks nice and feels a bit snappier, but now the battery is in the red in the evening after a full nights charge. This is even after severely curbing my phone use to try and extend the life. I have tried all the wiping tips and tricks too.
Same apps, different ROM. Darky's is an absolute nightmare for me and I will be going back to stock.
So is the ROM just another variable in the mix of battery issues, or the main offender?
Hello. I've the same battery drain, and I think it's very annoying when at evening you need to charge it again without using strongly the phone. Otherwise the Darky's rom, (I'm on 9.3) is very nice and marvellous, but this battery drain issue makes it worse.

Have you tried using spare parts to see which app is sucking baster or cpu? Did you download the rom configure tool from the market? Which gallery did you instal worth the rom?

This and:
have you let the phone drop below 10-5%?
Flashing screws up the battery indicator (how much depends) and it calibrates itself while in use. Letting the battery fall, or even the phone shut down by itself can speed up the process quite a bit. This helps only if there is no battery hungry app that's eating all your powrz though.
I haven't tried to see if there is an app sucking the life out of it because I never had any issues under the 3 or 4 stock roms and I haven't d/l any other apps. The battery deterioration started instantly I flashed with Darky's. I don't know which gallery it is, it came with the d/l. What ever it is, it doesn't work! No, didn't use the configuration tool.
I must admit I haven't let it run under 10% as I want my phone with me working. But wouldn't this manifest itself when I updated the stock firmwares?

ok mate, firstly search the market for the Darky Rom Configurator, shoudl be easy to find, you shoudl be able to reflash without wiping all your apps, run the config app first and pay special attn to the 'Lockscreen wallpaper' of the tool, there aint many options to choose. Got the gallery drain bit mixed up, sorry tired
If i was on my own PC id give a bit more detail but its pretty straight forward.
Im running 9.3 and get a full days mid-heavy use, i normally go to bed at 10-15% which is fine with me
cheers for the advice mate, I've just grabbed the app so I will do the flash in the morning.
I will report back my findings!
Just a thought but Darky's Rom uses JS5 and wondering if has something to do with the modem? Just a theory but wondering if you could replace back to JS7 and see if that helps. Just a thought. I'm used to a day's worth of battery myself these days.
The faster you make the phone go the more power you use darkest Rom are ok but messed with too much
I got really bad battery life for the first few weeks using darky. But now the battery life seems to be longer and more stable and average. I did do calibrations a few times tho.

You won't get better battery with Darky ever.
I played around quite a lot, 9.2, 9.3, calibration, fresh system, darky rom configurator, different kernels, lagfixes, no matter what, my battery drain was mad. It's a quick and smooth rom, but that's the downside of it.
I switched back to Doc's rom via kithen with same kernel, and quess what? No calibration, no playing around, nothing special I did and battery life is brilliant! Of course it lags here and there, that's Doc's drawback(no lagfix applied tho)
You will often find that if you flash a number of roms you get battery drain . Apart from the actual rom itself you need to flash to a clean firmware reset battery stats use a suitable modem charge battery once using bump charge method then wait a few weeks for it to settle down .
I am using rom kitchin since Darkys killed my battery life months ago .
JPY and JPY modem no complaints about excess battery life .
But i did flash back to clean stock before custom rom and wipe everything .

but this is true even if i use a kernel mod.. instead of a full flash? i think that a stock rom with custom kernel made for battery lasting is better... or not?
Have u all tried Battery Bump Charging?
Hi, I am not a Galaxy S owner but I am doing a research on this issue for a friend.
I am a Milestone user and I am a ROM slut (I flash many ROMs back and forth)
So I am very familiar with cases where after flashing a new ROM, your 100% fully charged phone is actually 60%/
Here is a posting on a few ways you can do a battery bump charge. When you perform this battery bump charging technique, u will be surprised to see that your 100% fully charged battery is actually not 100%

[Q] small newbie questions

I hate to make a thread like this, but it seems that this is kinda of those "everyone already knows this" or similar question that does not get brought up.
Anyway:
I decided to revert from genokolar's CM7 to stock Froyo firmware (functionality and hopefully battery life reasons, just one was enough of reason)
I found a update firmware in huawei's site for 2.2.2 Froyo, it was two apps in dload folder I had to boot into volume up+down+power boot mode, prior to this I had wiped EVERYTHING I could in clockworkmod, and after the update and few reboots, the system seems to be in working order. Even my recovery image is replaced with stock one now.
I know the CM7 port in question had some kernel modifications - especially ones affecting to CPU clocks, that in hand may be stuff affecting battery in negative way, and also imposing possible problems with stock system - does the stock 2.2.2 update also write in the stock kernel? If yes, thank you, I will be relieved. if not, then I need to figure some back plan.
P.s. waiting official gingerbread as is everyone else. Bug reports from many people about the official beta was one reason I went to stock froyo for now.
Thanks!
Yes it does. Or it has for me.
If I understand you correctly, you got worse battery-life with CM7 than you had with stock firmware?
I nearly doubled the battery-life going from stock f/w to oxygen, right now on MIUI and on my second day without charging

Well, It is combination of functional issues, general feel that the system may not work like intended, and to experiment will the battery life increase. Generally I looked the ROM selection for while but there seemed to be quite wide array of bug reports for each what I did not want to buy into. Unless there is some widely accepted strong recommendation for system - thanks for the input though.
Battery life can have a huge difference between phones. Also how much you use it has effect. I have better battery life in stock too i have used all rom except the new ics ones.

Yeah, from tests I hear if something, battery life in Hussein is quite great, at least in stock manner.
And my first problem basically was first night after installing CM7 and leaving phone, screen off idle, not charging, and during that 6 or so hours of idle, with wifi and connections turned off, my battery had been drained to half when I woke up and checked the clock.
Thanks tho. Not to say the ROM development are bad, opposite, they bring what people want, and already done better work at customized gingerbread builds for this device than Hussein with their betas. To me the battery life just is more crucial than the features of both 2.3 and the customized ROM.
also, thanks.

Battery Life BUG in ICS based ROMS

I've done a little research and there is a bug in the 4.0.3 AOSP release. You can see a link to this issue here: http://code.google.com/p/android/issues/detail?id=22878#makechanges
Attached is a screenshot of the problem ocuring in ICS Passion 13.1
I am curious is anyone NOT having this issue?
Yeah, mine started couple of days ago with the same problem. Android System shows 75% battery usage.
I wonder if there is a fix for this bug. I read whatever is on the link but there is all king of possible solutions.
I'm on MIUI and this is happening quite a bit too
Yeah, My battery will be 80% I reboot and it 10% or it's10% and I reboot then it's 80%...lol
I think, 84% is the culprit. Read my post here --> http://forum.xda-developers.com/showpost.php?p=23766036&postcount=2223

I used to have that issue on CM7 many moons ago. Did a bunch of searches and someone mentioned a process call GOOGLEBACKUPTRANSPORT.APK somewhere on XDA, that constantly runs even after you do not choose to backup to google (at least thats what I think its for).
I used root explorer to go into /system/apps and delete the GOOGLEBACKUPTRANSPORT.APK. I have never had any negative effect from doing it. It fixed the Android OS sucking up battery problem. Now I make it a point to delete it after flashing a rom regardless of whether batter drain is there or not. Never had that issue since.
Try it and see what happens. You can always just move it or rename it so you can put it back if it does not solve your problem.

Post to the Google Code bug
Just wondering if there have been any discoveries or new info on this problem.
I was experiencing this bug for a long time and I thought it was a bad battery. After replacing my battery it was still happening.
Battery life is the sole reason I went from ICS Passion (4.0.3) to Slim ICS (4.0.4).
I think battery life is better now, but I've also been incrementally restoring all my apps, ensuring battery drain isn't unreasonably affected with each restore.
I have this same issue! My battery lasted up to a day yesterday and today I had to charge my phone twice. Lasted only 4 hours. Pretty ridiculous I would say! I did try removing googletransport.apk and it reduced my android os to 25% or so from 60% that's about it.

Wow, this worked beautifully, thanks a mil illego.
Installed ICS Passion v13.1 a few days ago and had severe battery drainage, from 100% to 0% in 8 hours after calibration.
Looking at the battery stats I realized that the phone was always in AWAKE mode, with ANDROID SYSTEM sapping like 80%.
After renaming GOOGLEBACKUPTRANSPORT.APK the phone finally went into much needed sleep mode.
In hindsight, I enabled Google "Backup this Phone" during first ICS setup, and this must've tried to connect to the internet the whole time or had a process keeping the phone awake.
Brilliant fix, you made my day, thx.
I was using ICSSGS's 4.0.3 and noticing that my battery was draining pretty quick with little or no use.
I decided to try the Dark Knight 4.0.4 rom and my battery life has pretty much doubled.
No lock screen issues now either!
SlimICS!
I have been using SlimICS and have never had any batt drain issues. Googlebackup.apk is removed by default from this ROM.
I never get good battery life on a ics rom, tried on 3 different phones with 6 different roms. It looks nice but isn't battery friendly from my experience.

You must have one or more apps draining your battery.
User betterbatteryStats or "BadAss battery monitor" to check where battery is being used and whether any app is keeping the phone awake.
I agree
I have to agree. When I use a Froyo Rom my phone loses .5% per hour in idle. At times it loses a max of 1% per hour. However, with ICS ROMs I lose around 1.7% per hour. I have tried just about all ICS Roms, and all Kernels. While some are better than others, 1.7% per hour is pretty standard with any ICS. Trust me, I have no deep sleep issues, and no abnormal wakelocks. I've read all the post of saving battery life, and done them all. Roughly 1.7% per hour is what I get with any ICS Rom.
Personally, I like the look and feel of ICS so I just take the good with the bad. Can anyone shed some light on this. Why does ICS drain battery so quickly in idle vs older android versions. Or, is it just the Vibrant? Im stumped.

Curious observation in battery life on ICS LQ3

I have noticed accidentally yesterday that after I had my stock headphones pluggeed in the Note, the typical curve of the battery drain became much flatter and the different wakes during screen off have almost disappeared. The moment I unplugged the headphones, the battery drain went back to the usual 2-3% per hour on standby.
I am running stock LQ3 and stock kernel. I am rooted, as I have flashed it through Mobile ODIN, over stock, rooted LPY.
I have quite a lot sync-accounts - twitter, facebook, gmail, email, weather widget etc. so I am quite used to relatively short battery life but the trick with the headphones came as quite a surprise.
Before writing this post I decided to test it today as well and it is the same.
So, could someone test this and report? I think that if this proves to be true and common, the devs could easily track what's happening exactly and sort things out, so that battery can live longer without the headphones plugged in.

Ugh...I am terribly sorry, this was meant for the General Discussion. Please, admin, move it there.
I've noticed that same if the SAR of the last samsung mobile is very low, the reception is quite good compared to other phones.
Do you notice also an improvement of the signal reception? Because if it is the case, it is that your headphones are used as a secondary antenna, giving the phone a stronger reception and less power consumption (better signal = less need of power usage for processing the signal)
This is just a theory...
After some ICS ROMs I went back to Gingerbread, mainly due to poor battery life.
When Litening ROM 2.0 was published I flashed that one. I liked the GB version a lot. The battery life was remarkable, a lot better than previous ICS ROMs. Because Litening is not much supported I tried Alba, also LQ3. A surprise because battery life was the same. I think I'll stick to ICS this time.

Alba often uses LB2 modem (from GB) in his ROMs - maybe it is the reason. I myself observed huge batterey drain on latest ICS ROMs while connected to Wi-Fi at my workplace. Fixed it by flashing ZCLP5 modem (from early "LP5 leak" ROM).

Hm, that is an interesting theory. I am not sure, however, that the headphones' cable really improves GSM radio reception. I think it is only for FM reception. Of course I have no knowledge behind that, just thinking.
I have frozen lots or apps in Titanuim Backup like:
- the whole range of SNS's
- Social Hub
- Wi-fi sharing manager
- the infamous wssyncmlnps
- software update service, etc
Also I have stopped a bunch of receivers, using Autorun Manager Pro, and disabled a lot of processes from Autostarts.
This should mean that I have opted out the most common battery drainers. I have tried to disable auto-sync for the time being, but that does not seem to be much of a drainer, so maybe the real problem comes somewhere from the modem.

Hey dimcus, i've been having this WiFi vs battery issues with some routers(including the one at home), weird enough it doesn't happen on some of them. I did read somewhere about flashing te Modem file, what leads me to a couple of questions ir you don't mind. Are you on ICS? Do i need to be root to flash the Modem file? If not, any risks involved? I'm on stock ICS LPY DBT.
Thanks in advance,

I flashed the ZCLP6 modem earlier today, guessing that it would be better than ZCLP5.
It is too early to judge but first impressions are that maybe there is a slight improvement in battery on 3G but not something worth it over the stock XXLPT that I used to have and generally battery drain on wifi seems as bad as it has been ever since I flashed ICS.
I have read that some people dared to wipe their Notes and after that most of the problems had disappeared but I don't want to risk getting some brick.
I will try several other popular modems and will report back.

Unfortunately after several different ICS Roms (From Stock LPY to Cleanote 2.20) with several different Kernels (Stock, SpeedMod, Goku and more) and few modems (XXLPT, ZCLP5) I had to go back to Ginger due to extremely poor battery life. With all roms /kernels/modems combination the behavior was very similar. The phone was going into deep sleep pretty easily when idle with very low battery drain. On the other hand when using the phone I was getting about 10% drain each 20 minutes (A little less with data wifi and all sync off). I was also getting overheating with temp most of the times over 40 deg C. This drain was almost the same even with system energy savings on. I could not understand the reason for this strange behavior considering that many other users are having great battery life on ICS with their devices. Anyone is experiencing this situation ? NB now with Ginger the battery life is ok.

Battery drain with cm10 paranoid android

Need to continuously watch the battery as it drops about 10-20% on idle. Checked the wakelocks and mainly wifi related, the phone is going into deep sleep just fine. HELP PLEASE!!!
lol continuously watching means you're the wake lock.
btw phone only has 3-3.5 hour screen on time. When playing games its usually less.

New Battery Drain Information - stock unrooted firmwares

Hello, let me cut to the point. Testing a few nights while sleeping from around midnight to 7:30am on different firmware versions, i can confirm.
- Stock, unrooted, firmware verison Taiwan, 253: BetterBatteryStats drain overnight : 0.7% per hour
- Stock, unrooted, firmware version Hong Kong, 253: BetterBatteryStats drain overnight 0.3% per hour (Update, last night was 0.1% per hour, woke up in the morning with 100%)
In conclusion, not all firmwares are created equal. If you have the dreaded battery drain problem - try another regions firmware. The HK version definitly does not has the drain problem, and its quite a generic firmware, so you can customize it to your region no problem.
In Both firmwars I had WhatsNew, and all smallapps hidden/disabled via the adb "debloater" app.
PS: Taiwan is original firmware of my phone, I am expat living in Taiwan.
Why HK firmware has more battery? lol

how do you disable whatsnew without root?
I think the firmware 253 is the same for battery management for all versions.
I think a good thing to do sometimes is clearing cache in recovery. For me it help when performance become slower.
But few parameters can really change your battery drain like the Temperature in your house, usage during the day, network level, running process, humidity....
Maybe that's because some differences of LTE bands support?

I thought the same thing but shouldn't that be more hardware related?

LTE is disable on my phone on all tests. All my testing with done with 3.5G and wifi off.
VoLTE is something i noticed taiwan firmware had, but HK didnt. however I had it turned off in both cases.

I know most people most people would like buttery is the same for all version. That why I am posting. Caches etc all cleared, phone got full wipe when switching firmware.
This test is verifiable and repeatable. I tested both firmware at east 2 times each before posting, and the results were the same every time. Same phone, exact same apps installed, same firmware version - different region = different battery drain.
Can someone upload .253 stock kernel with SU and DRM fix for me? I want to do some further testing but I'm not able to extract it myself for the next week.
the Wifi-allways on bug
did somebody changed already the default:
Settings->Wi-Fi->Settings->Keep Wi-Fi on during sleep
(the good old bug - if you look at the other threads)
one solution I had for battery drain even in marshmallow is to remove the sd card. Yes, I do know it defeats the purpose but I'd prefer not having to worry that my battery will drain by 30% overnight.
SDcard?... did you try another one...
How can I know which firmware do I have? The number is 32.0.A.4.11
32.2.A.0.253 here and I'm seeing Android System keep awake for over 11 hours.
Google Services mobile radio active for 27mins.
No other mentionable apps.
Any luck with the battery drain?
Some good news for me and maybe for others may be helpful.
I flash clean new 305 FW and modified stock kernel from here
http://forum.xda-developers.com/z5-compact/general/customized-stock-kernel-32-2-0-305-6-0-1-t3477464
With root i delete some system apps (mail,gmail,gdrive,maps,whats new, all about small apps and etc.)
Now 3% at first night(9h) after flashing FW in standby mode and all data off without stamina.Its first good result for me.On all others 253 custom kernels was ~7-10% at night sometimes more...
I stay on this FW and kernel.
