My issue with Samsung 4,3 based roms is this:
Badass battery monitor always shows kernel on top of my battery usage charts. Normally on 4.1.2 based roms the kernel would run for about 12-15 minutes over the course of battery being used form 100 to about 10 % but on 4.3 on the same usage kernel is runnning for close to an hour. Also Android OS always tops my battery drainage charts irrespective of what kernel plus rom I use.
With the same set of apps I had pretty good battery life on 4.1.2 but not so good on 4.3.
BBS also does not show any weird behavior.
Any pointers as to how I can prevent kernel usage from being so high?

First of all- what build versions / kernels did you use? I'm running Neatrom's NA5 version with stock kernel and it seems to have the best battery life i've ever seen (even compared to 4.1.2 roms) (it can be better using Boeffla kernel, but for me its more than enough)
Second- try to set off 'Scanning always available' in wifi settings, and look for 'location settings' in Google Settings app- they cause a huge battery usage

I used omega v54/55 as well as the last 2 versions of neat rom. Currently using the NA5 one. On Stock kernel. Tried boeffla as well.
Wifi Scanning off. and no location services as well.

This may look like a silly question, but you have playing around with ROMs istalling few daily, or you've let them settle. I used to change them few times/hour, but now I am really happy with SmartDroid Lite v5 (ex ZDroid). It really is a difference compared to when I instlled it 3 days ago. First, it was like 7-10% dropped in the first night. Last night I got to bet with 43% (23PM) and woke up with 43% (8AM). I never believed the others when they said that. BTW, I am using latest AGNi Stock 3.5.1 kernel.

Should the battery drain in ICS version be so bigger than in gingerbread stock version?
I use MiniCMSandwich Lite AOSP but even with gouvernor and io scheduler set, the battery is gone in less than a day...
Do you have any ideas? I disable all unnecessary functions when not used.. :/
Likely yes because ICS is more demanding.

So in general, with the same usage behaviour, ICS will have greater power consumption than Gingerbread? I also have Huawei U8800 with Aurora ICS installed and didn't see such a difference compared to stock 2.3 firmware :/

ICS is bigger, more powerful, which means it will require more power from the phone and also more juice.
i used active n lww. both are using ics. but, the active the battery drain is so much more than lww. even when i try to use stock rom n kernel (my lww bootloader can't be unlocked) my lww stil can survive 1d 14h (even more) , but my active can survive max only 1 day..
i use both with the same usage of call , internet , messaging
My active lasts almost two days with data/wifi always on and normal usage, a few days ago, without any gaming i had 56hrs running before i had to recharge...I use JD plus and performance boosting scripts (and anonmous' excellent kernel) and also i use miui (but i think any rom can use it) which has lbe guard which allows to prevent any app from autostarting
yup, I've noticed this too. ICS drains battery way too fast. I'm using Active and have tried both stock rom/kernel and custom rom/kernel based on ICS. Now I'm back to GB, Spartan ROM / Rage kernel, battery lasts a little bit longer, half a day more I think. What's the practical advantage of ICS anyway? I really didn't notice any, hehe.

could you give me a link for performsnce boosting script ? and what kernel you use ? i use mesa v1.8 ... at least the battery drain is not so fast like krsh or rage kernel
I also use mesa

Hello all,
I have a question for you all:
I have flashed a new rom today and have decided to NOT activate Google Now, and (after a few hours only), I seem to see a much better battery use?
Is it possible that this app, being monitoring so much all the time hoggs the battery quite a lot?
So, placebo effect or not?
Certainly possible I suppose, but I haven't noticed it drawing a significant amount of juice on my S3 or my Note 2.
I've had Now running in the background on my Note 2 for over 9 hours and the battery is still at 92% (minimal usage, just on WiFi), and while I'm getting tired of being notified about the ManU match, it doesn't seem to be drawing an inordinate about of power to run.
Is the new ROM you flashed using a different kernel or a newer revision of your previous kernel? In my experience, that's been the biggest factor in terms of power consumption.

Well, I am using temasek's CM10 Kang (70 I believe, latest anyway)
and with the kernel that came with it.
I ve tried other AOSP kernel, but no boot at all, so...
What I think is that XXDLIB modem does has a noticeable effect on good reception over here, so maybe that s the factor here?
Self explanatory really, I much prefer having stock android on my s3 but the battery is much worse compared to roms running on a Samsung base.
I would like to know if this happens to everyone and the reason behind it since I've read the "nexus edition" S4 actually has better battery results than the Samsung variant.
Many thanks

Samsung includes a lot of battery saving technology in their roms but it is closed source so developers cannot access it.
I run a custom Samsung ROM and an AOSP - battery isn't noticeably different. I also use Greenify and I turn off auto brightness (run it about 50%) & blocki9ng mode. Overnight I see my battery drop by between 3% & 5%. 15 hours of normal use sees maybe 30 - 45% battery depending on how much game versus phone/SMS.
Best battery so far is 54 hours and at 28% - I was in Melbourne via train and forgot my charger. I know it is the TYPE of use that matters but I was making/receiving calls and spent about 45 mins as hotspot to the wife's laptop.
I run GoogyMax, v6.1 Purelook HD ROM and SlimBean ROM v 7. Haven't found anything not working, haven't got FC's.
Both ROM's installed on full wipe.
All Cyanogenmod roms over 10.1, aosp, aokp roms make my battery drain so fast that I can't even get a half day. 1 to 2 hours of screen time only. I don't have this issue with sammy roms. I did a full wipe (even the internal sd) with some scripts i found before then flashed the roms normally also tried different kernels but nothing worked.
Same problem here but I think it has more to do with exynos sources. No sources, no CM love.

First of all, in my experience, Samsung TW roms got a better battery life than AOSP/AOKP, whereas for instance SlimBean + GoogyMax now gets me around 24h with around 2h screen on time (on average).
What you could you is, if you did not do already, use BetterBatteryStats to identify the part that is draining your battery.
Yes. Aosp roms do drain battery faster. You can do nothing about it, it depends on the rom, even though some people do report they get good battery life on specific aosp roms as well (these are almost never CM or PA though, especially PA).
So, it's rom dependant for the most part. Try flashing a different rom...

Any suggestions how to keep battery life longer with roms higher then 4.1.2? Every time i flash rom like cm kitkat, paranoid 3+ or higher my battery life sucks (battery life to 5 hours). And with 4.1.2 roms battery life is just awesome (about a day).
Sorry for bad english.

The reason why battery life is noticeably worse on kitkat is because of the lack of drivers available for or device. It isn't well optimised for our device and as a consequence, battery life is lost. If you absolutely want the best features (in kitkat) and want reasonable battery life, look for roms that have been built to be as close to aosp sources. That is look at rom like slimkat or neatrom aosp as they seem to have the least bloat ware and are running on the latest version of kitkat.

And how about kernels? Do they have any impact on battery life?

Kernels can provide driver updates to the graphics therefore there may be better performance in games. Most custom kernels allow the user to undervolt their cpu (and sometimes gpu) therefore accounting to battery savings. So yes, if tuned properly (sometimes if custom kernel settings are left to the defaults), there may be a slight improvement to battery life. As I said before, I can only recommend to you aosp roms such as neatrom or slim saber rom if you want minimal battery drain.
