So, one thing I've noticed when running through the various ICS ROMs and kernels is that regardless of rom or kernel, Android OS eats up battery at an alarming rate.
In my experience, it usually is eating more power than the screen, which just aint right. Now, I know these ROMs are at an early stage, but this is a common thing between all of them. I've noticed a few others noting it, but I think most are too excited about the new OS to notice the batt life.
Has anyone narrowed down what's going on? I'm curious....
**NOTICE TO FLAMERS**: This is not a post passing judgment on ICS. I'm simply asking if anyone's figured out what the issue is currently, or if anyone has solved it.

Don't form an opinion of ICS until you actually run an official rom, and not something someone hacked together from AOSP release from a different phone, and leaked dev binaries.
I see this happen too, on the rom i am running. but won't form an opinion until there are proper roms out.
my battery life is great. I get 15+ hours on mine with no issues at all.

Jesus christ, I didnt form an opinion of ICS. You need to chill dude. Re-read my post. My post was an inquisitive one, because I recognize that it is some sort of bug or anomaly in EARLY CUSTOM BUILDS, as can be seen when I said "Has anyone narrowed down what's going on? I'm curious...."
There was no need for that....
it doesnt necessarily mean that the android os is using more battery. you can also look at it a different way.. maybe the screen is taking less battery. if the android os uses the same amount of power as always, but the screen uses less, the % battery used is going to go up for android os.
Yeah, but the likelihood of a hardware item suddenly using less power than it used to is certainly way less likely than an OS, software-level item.
I understand your theory on percentages, but as I'm sure you've noticed simms, something's draining the batt quickly, even on UV kernels, and I'm willing to bet it's OS related, and probably related to Android OS (in batt usage). I doubt this is the type of batt life we can expect with the official OTA, so I'm thinking something's running amuck.
My screen used 26%, while Android OS used 39%. In the past w/GB roms, it would have been more like screen 45%, Android OS 11-15%.

im just playing devils advocate, to try and see it from a different point of view. right now my screen is at 43% and android os is at 35%. normally my screen is around 51-57% and android os is around 7-11%. mind you, i am tethering at the moment also. but, the screen % is below what it normally is and the android os is much higher than it usually is. so something is definitely going on.
btw, in on the seuv kernel, and its doing alright on battery for me.
i am usingkoush v11 with Franco 26/11 kernel. Off charge at 9.30 am at 98%...5.30 pm 89%...very little usage today..just a couple of emails..but easily getting 15+ hours of battery life with WiFi my main usage including phone calls over WiFi.
My phone is turned on for 17 hours 38 minutes and still has 24% battery with brainmaster v5 + franco kernel
I've noticed this, too.
Last BM version drained my battery massively over night while being in flight mode.
Android OS took 87% of the battery in 8 hours.
So it's definitely a bug.
CM9 Alpha 11 is way better. In 18h 36m Android os 25%, android system 17% Display 15%.
Even though i appreciate the work the devs who are coming up with these ICS roms are doing, i can't use any of them as daily drivers (no flash/Google calender sync issues/performance is noticeably slow e.t.c). Played with Koush's version the other day and was mighty impressed, very. I'm still not sold on the whole ICS look in general, might take a while to get used to it. Seems too fluffy to me, too much eye candy. Battery life wasn't the best, but manageable.
Right now i'm on Oxygen+Carbon rom mix with Franco kernel, and OMG this combo is phenomenal regarding performance and battery life..
my battery life is the same, if not a tad better.. using kwiboos v2.

Same here. No custom kernel, no tweaks, no trickery - running Koush's V10 out of the box. Runs smooth, quick, and I go from dawn to dusk on one charge with lots of browsing, app installs, etc.

With all due respect, "Don't form an opinion of ICS until you actually run an official rom " is not a statement of fact, it is your opinion/emotional response based upon you misunderstanding of my post. I clearly acknowledged that we were working with early builds, so this is obviously not what the final product should be.
The purpose of this general forum is to have general discussions, and troubleshooting posts. I made a troubleshooting post, seeking out others experiencing the same thing, in an attempt to solve the issue, or see if the culprit has been found.
I will admit that I overreacted a bit, but I think you did the same.
I'm gonna leave it at that, otherwise this'll turn into a flame war.

I'm curious: check your batt usage. Do you see Android OS almost equal, if not higher in batt usage than the screen?
Now remember, on phones, the screen is the biggest power drain for anyone other than a light user (never turns on screen, makes 1 call a day, etc). Typically, in my usage (usually 25-30% brightness), the screen takes anywhere from 40-50% of my batt life thru the day, with Android OS way down the list. That was Gingerbread.
Android OS 38%
Display 29% (brightness at 12%)
Miren Browser 17%
Cell Standby 9%
74% remaining
8hrs 44min on battery
Sorry, my native screen cap won't save to disk, otherwise I'd upload it.

Yeah, I figured it'd be way up there. Now, I'm not saying batt life is BAD. I still can get a good 15-20h out of it if I dont use it much. But I'm used to going 24-36 hrs without having to charge, all with medium usage. I've tried various UV kernels to achieve this again, but Android OS is dominating the battery.
My battery is actually good. I am on cm9 alpha 11 on franciscofranco's kernel. It lasted more than 24 hours on medium use.
more than 24 hours is already good for a smartphone.

yep. My first impressions for it were the same, too much eye candy and too much things going on the screen. Maybe I was just used to the very simple and minimalistic UI of the stock gingerbread. But after using it for a day.I am beginning to realize how amazing and beautiful ICS is.
Yes Android OS is top for me at 45% and on GB ROM it was 4-5%. Batt life ain't too bad but I think the Android OS usage is just something that will get sorted as the development moves forward, especially after the official update drops.

Well I am going back to stock for good (atleast for now). I have been with android for about two months coming from 3 years of iphone. I didnt mind the iphone, but wanted to be able to do some customization to it.
I have played the ROM swapping game since day 4 of having the android. Tried several versions from 4.04 to superlite gingerbreads. The thing is, people always say they get better battery life etc etc... but I have yet to see it.
I keep data, wifi, GPS off when not in use and all notifications off. I love the android dont get me wrong, but when it comes to battery life, the iphone kills this phone. But, in defense of the skyrocket, it has a much bigger screen which I am sure contributes to large battery uses. I have found that the stock version tends to give me better battery life.. so stock it is for me.
I don't really see the additional benefits that custom roms offer over stock for the battery life, despite how often the developers update their custom roms and peddle that they save battery. But the additional features that come with custom roms are indeed nice.
Still, should outlast the iPhone 4S any day. I get over a day's worth sometimes if I'm not doing heavy usage.
If you haven't tried MHX's Superlite 3.1, I recommend it. Using it on GB, I got fantastic battery life.
But understand this, ROMs do have only minimal effects on battery life, the level of debloating being the big thing. Kernels will have a bigger effect when used correctly with good CPU management.
But the biggest effect on battery life is you and the apps you install. You need to watch like a hawk with BetteryBatteryStats and CPU Spy to see what's really going on. See what apps are killing your battery and why. Eliminate the problems and you will be set.

Yea... it's like im sorry you couldnt figure out whats eating your battery... but do you really think everyone on here just uses custom roms regardless of horrible battery?
OP, your aruguments might apply for the iphone 4, but no way it does for the 4S. This would be like comparing the original galaxy s. The 727 is a powerful phone and lte is a *****. When i'm on Wifi, i can easily have a 30h battery life, but as soon as i'm on 4G or Lte, battery life is a *****. Its life and until they make some kind of super capacity compact battery, it will be the reality of a decent smartphone.
On the other side, i also reverted from ICS leaked roms to stock GB, unfortunately, stock has always been the best choice for me, much stabler than any rom

Yo try faux kernel with stock gingerbread and if you don't get better battery life then somethings wrong with your phone. I've gotten up to 4 hours screen time on with it. I also froze a bunch of bloatware.

Hi, so I recently got an Infuse from someone that is still on Froyo and I figure I might as well upgrade to a custom rom.
Since I care about battery life the most, I figure I would ask which version of Android provides the best battery life for the Samsung Infuse: Gingerbread or Ice Cream Sandwich.
I probably won't be running apps that fetch/push for data a whole lot, which obviously helps the battery life. But I thought I'd ask to get someone's opinion on this specific phone and a comparison between Gingerbread vs ICS before picking a rom.
And the winner is... Gingerbread!

Gingerbread is a better battery saver. Although i get decent battery on ics and jellybean. I know i perfer all that ics/jb has to offer in features over having battery life. But for what your asking id suggest AEON or the stock gb. Aeon is very stable and has some cool extras without much battery drain

I have never payed that much attention to battery life..

Sent from my sweet & buttery Infuse
the more recent ics and jelly bean kernels get great battery life due to fixed bt and wifi drivers (the wifi driver and binary were taken from another device from what i understand) and more stable cpu clock code than it had initially. not too much more than stock but i have to say it is better for me. but i guess it all depends on usage. one may have better standby vs awake battery life or something. the available kernels have been this way for atleast a month. when we start to see more kernels with undervolt it should get better yet.
I'm using CM10 8/23 and my battery life is good.
One of the best I even made a snapshot (can't upload right now): 51% left after 12 hours 46 minutes.
That's why I'm in a dilemma between jelly bean and gingerbread. I do appreciate JB a lot, way better functions. But still the battery life and compatibility are big issues. I can get 2 days under gb but only less than 12 hours in JB, that's a big issue.
I have been getting great battery life with the latest JB ROMs I have been using. Pretty much on par with the GB ROMs I used.

Can't say i've had good luck with battery life, I used to average 3 hours of screen on time in Gingerbread, but since moving to ics/jb that has dropped to anywhere from 30 mins (if i leave the phone and standby drain eats it) to 1 hour 45 mins on a single charge...not good.
No rogue apps, no media scanner (i constantly check these things with betterbatterystats, i don't install anything i didn't install on gingerbread). Just the cell phone standby drain eating my battery alive (BBS reports it as GTALK_ASYNC and RILJ wakelocks).
I've been researching it for months now and get various answers (the wakelocks are caused by bad APN settings for example), tried all the fixes, still no luck. I suspect that it's probably a Rogers thing but who knows.

I've been playing around a bit with different gb kernels, odex and deodex.
I found the drain issue much less on stock uclb3 kernel and rfs file system.
Almost all drain were associated with being on wifi...wakelocks and something else kills the battery.
If I have wifi off, there is usually not any issue.
You may have to play around a bit to see. My experience on cm9 and cm10 has been limited. I have noted several users noticing drain on cm9 and cm10 as well.
To avoid drain:
1. Use it to the max and constantly.
2. Leave the phone on airplane mode when not in use.
3. Turn off data (wifi and mobile data) and background data when not in use. I use this last mode.
Thanks for the tips man :good:
Airplane mode of course makes batt life better (disabling data doesn't), but when I start having to make sacrifices I didn't have to on GB it becomes a problem for me. Why should I jump through hoops and gimp my convenience for battery life that still isn't even as good as GB?
Instead of that i'd rather try to find the root cause of the problem. Doing so then allows us to help others that may have the same problem.
It definitely is an issue with the radio (or rather CM code overlooking something concerning the radio). What exactly, i'm not too sure. I've tried different modems as well, UCLB3 on JB was awful for battery life, UCKL2 and UXKG3 are slightly better but still not that great.
I don't want to complain about these things, I always try to research first, but damn....i'm stumped.

Yeah, I agree with you there. The techniques I use is pretty simple. Pose the hypothesis. Start with a full deck and slowly eliminate or start minimal and add.
ex: flash jb without gapps; without microSd. try different modem; try a different kernel. different kernel from different build.
have to use it for a few days to find out.
do the same for cm9.
add gapps...
add microsd
etc..
at some point, you will find out contributing factors.

I don't want this to turn into a "my ROM is better" thread by any means... but as a newer ROM flasher, I was wondering how much difference a different ROM would have on battery life? I'm lucky to make it 8 hours on my Skyrocket right now even idling... and while I like the ROM I'm on now (Embryo), it's almost unusable as a device this way for me.
Thoughts?
ROMs definitely have an effect on your battery life, as they govern what's running in the background and how the system operates. Some ROMs are optimized for battery life, and some are optimized for performance. The OP and ROM thread will usually tell you which is which.
That said, if you're only getting 8 hours of battery life on Embryo 5, there's something else going on. Check the link in my signature for information on hunting down and wiping out wakelocks, and consider underclocking/undervolting and changing the governor.

you should check out the battery life help thread as it has almost every possible detail of enhance your phone battery performance. when im running embryo i always get around 22 hr with 2 hrs on screen so there something your missing. and every rom with have different battery performance not all because of the tweaks and rom enhancers but because of the user. a person who is surfing the web all day with little phone and text will easily drain battery. but a person who mainly running music social browsing talk text can easily get longer battery life.
No offense man but if embryo's rom is considered "unusable" then use another rom
Hey im looking for a rom that is great on battery. I just got up an hour ago and my battery is already at 90%. I feel like its going down too fast. Im using Purity rom with greenify.
Hi,
Better is to try by yourself, battery life is mainly based on your own settings and usage. If you have some rogue apps, bad network reception and your brightness at 100% (it's an example but I think you see what I mean).... Whatever the rom it will be the same thing.
1 hour... 90%... all depends of what kind of wackelocks you have, synchro, etc...
There is a ton of thread about battery life, take a look in them for help.
And: http://forum.xda-developers.com/showthread.php?t=2477889.
And also purity is awesome on battery life when I was using it... There are way too many factors to consider when talking battery life.

Stock Rom works very well. But it really does depend on the processes you run and the apps you install. Thus "best" becomes a relative term. If you have very bad network reception I'd recommend installing a kernel like Franco kernel. It stopped draining my battery even in areas of bad reception.
As it has been mentioned, battery life depends just as much on you and your usage / location / etc / etc.
Something tells me though that the roms that have in their title: Battery Saver Script might be something that focuses on what you are looking for. Just a shot in the dark...

One of those was literally on the front page of roms listed in Development.
I use omni rom with franco kernel r31 and I get 3 hours screen time with about 13 hours battery life most days. I use the internet a lot and text all day.
There are too many factors that affect battery life but also these threads are not allowed on XDA, as pointed out above. Try some out yourself and see which best suits your needs.
