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.

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.

So from a GR-12 standpoint I must say gingerbread handles just about everything better. with the random odd bugs here and there... so far gingerbread is already showing some awesome stability and speed. much kudos out to the devs here! You guys do a great job and from what I've seen here so far... you put up with maybe one too many ignorant rude individuals. BUT! I would like to extend my thanks to all you devs and helpful members here... and for making my switch to android not only an informative one but a great experience all together.
So... anyway. loving gingerbread (GR-12 mainly). After loading up launcher pro almost every single bug or issue has vanished. seems the twlauncher has some deep seated issues lol.
Looking forward to the new releases!
I totally agree, Ive been running GR-12 for a couple of weeks now and its silky smooth. Oh and im also using launcher pro for the same reasons. lol
A different launchere makes all the difference doesn't it!? After I realized that every time I had a snag or crash it was "twlauncher"... I figured I'd try replacing it. and sure nuff... Awesomeness came spilling forth. Honestly haven't had a issue since. (well I flashed the kc1 modem which gives me the gps performance I need... ).
Outside of my own retarded moment bricking my phone while flashing it... Tearing through 3 old power supplies to get the right combo of resistors to build my own jig.... lol! But all is well that ends well.
What's everyone else's setup / experience with ginger on their cappy's?

significantly better than froyo (at least for me). There are some people with a battery drain issue but I'm thinking its an app thats not optimized for GB. I dont think its a ROM or KERNEL issue - but I'm not a dev so I can't back my statements up.
Both battery and gps are better on GB. Gps is wayyy better...

Are you able to give me like how many hours on average you are getting? I appreciate all the solid feedback.
Gingerbread has been horribly buggy. The battery life is just plain awful, it's laggier than 2.1, and it killed my dog.
Someone was bound to say something negative, so I just got that out of the way. Lol
Actually, GR-12 makes my Captivate run as smooth as my Inspire. I got about 12 hours heavy usage with the screen almost max.

that's a loaded question because it depends on MANY factors:
-signal strength in your area
-3g vs wifi connection
-general phone use (phone calls, sms, games, etc...)
For me, the phone lasts MUCH longer. I can go about 20-24 hours until I need to charge again. Thats with medium use and wifi connection 80% of the day. On standby, my phone usually drains 1% - 2% an hour.

That is good to know. I will keep that in mind.
So far on continuum its been rather smooth, using go launcher btw.
Battery life is bad though. Less than 8hrs with moderate to heavy usage. I need to fully recharge two to three times a day now.
On froyo I'd get 12-15 hours with similar usage.
Gps works fine, but then mine did on froyo before.

I'm experiencing battery drain, GR, Continuum and Mosaic, I leave wifi on and after 9 hours (fully charged, battery stats reset, standby mode [literally 0 use, I was asleep]), cell standby had used 33%, wifi 30%, .... I had 52% battery left.
GB is smoother, for sure, once kernel development ramps up for GB (JVB, JVH and JVO, ... JV#) i'd expect to see more tweaks include power and performance.
If you need battery life and don't want to risk flashing GB, wait.
battery life *IS* going to depends heavily on how much you use your phone. It's hard to compare battery life amongst people that cannot stand next to each other and compare phones because describing "heavy" use is different for everyone. My version of heavy is not the same as the next person.
the only real determinant of battery life that we can all use as a comparison is to see how much battery drain you have on standby or to run some sort of application that runs videos (ie. benchmark apps) because we can all do that. If your phone drains 2x as fast as mine on standby, then we have a problem with a rogue app or something else.
(clarification: I dont mean to use a benchmark app to see the results of the app itself. I just mean to run something on the phone to drain the battery quicker and view the battery life at the end of the test).
I've always experienced better battery life with Froyo, and I use my phone every single day for reading PDF's, listening to music, texting, calling and surfing the web. Maybe Gingerbread has better standby battery life, but when getting a "full" use out of my phone I've always lasted longer on Froyo builds.
Is it just me or do i get better battery life on sense froyo roms then i do on aosp gingerbread roms. On aosp i lose anywhere from 7-10% battery per hour, standard use, and on sense i lose 3-7% per hour, standard use. I am on Bamf Remix 1.8.6 with the desense script, and the aosp roms i tried were cm7 and omfgb. I really wish i got good battery life on aosp, it is so much smoother and quicker, but I need my battery to last as ling as possible. Am i alone here or what?

You're going to get better battery life on Froyo over Gingerbread.
What are your setting though, I go all day with pretty good usage (browser/text/facebook/youtube/Music) and I'm always good to go.
I'm running CM7 stock kernel. Display at 40%, 4g disabled when not needed, Wifi disabled when not home and I can't really say I have any complaints.

just curious did you wipe batt stats do a full drain and recharge and see what you got after that?
No, I'm guilty of not doing that. I guess I should try that shouldn't I?

Although that's an obvious solution. There's more he can try before he goes to spend the money for an extra battery. I honestly don't see a need for an extended battery and I play around on my phone all day. When I get in the car charge it. When Im at home on the pc charge it.
I definitely get better battery life on Froyo sense than aosp gb. I, personal, think I get the best battery life on a stock version. I'm currently running the rooted OTA and the OTA MR2 radio and am getting great battery life (4g off, don't have it in my area till the end of the month).
I wish CM7 got good battery life. I like it better than any ROM I've tried, but can't get over the battery drain. It's ok though, I like Sense a lot too.
But you know what they say: To each his own.
to each his own is right
But on the same platform (froyo vs gb) i just dont think you are going to get tremndous variations in battery life. There may be an outlier rom that uses it quickly by most of the roms are in the same ballpark. i think we are talking about squeaking out an extra 20-30 mins which is not nothing but 8+ hours of a battery charge i would be more inclined to go with whatever rom i like best. When GB is released for real, then we may see some improvements across the board.

I have to agree. CM7 has been way better than any other rom i've tried.
CM7 with Kang Bang does best on mine, but you can't compare sense froyo to aosp GB. That's too many different factors. That's a different framework, different kernel structure, different ROM. How do you know what the culprit is?
I'm running BAMF 1.8.6 as well on standard battery.
I just charge at night, take the phone to the car or motorcycle for commute and place on charger. When at work, I have another USB charger with micro USB cable. Charge when at desk. Reverse procedure for drive home.
Battery is great when only off the charger for ~4 hours per day. :-|
It seems that sense battery life is better. I've been on cm7 for a couple weeks now and my battery will be nearly dead by this time every day. So I'm getting 5 to 6 hourz max with cm7. I'm on gingertheory now with dream kernel and setcpu running a few profiles, battery life is at 70%. May have been using it a little less today but still that's a big difference.

Getting the 2750mah extended was the best investment you can make into this phone, hands down. If your phone goes naked, then the difference in thickness is not that bad. In fact I love the new added thickness. It keeps my camera lens off the surface when I put it down flat. Not to mention it adds a certain heftyness that just exudes quality.
Sadly though I got an unlucky battery cover which creeks if you squeeze just a smidge on the sides
Other than that, man is it great. I can go about 48 hours without charging on CM7.1. At the end of the 48 hours, my screen would have been on for roughly 5-6 hours. That means nearly 3 hours of screen on time a day. If you sleep for 8 hours a day, that leaves 16 hours of awake time. 3/16 means nearly 20% of my time awake was spent looking at my phone. Hardly minimum usage, and if its not considered heavy then I fear for future generations. Screw these kids today 12 years old with a smartphone lol. I didn't get my first cellphone till I was a senior in highschool (2004) and even then, it was a crumby flipphone just for the sake of making calls and in case I was in trouble.
Hey all
I am loving ICS on my Xoom. However, I have noticed that "Android OS" is taking up tons of battery, with high awake times. I have had it unplugged for about 3 days, and the screen has only been on for like 2 hours. However, "Android OS" is the highest battery eater on the list and has kept the device awake for over 10 hours. Anyone else seeing this? I am having the same problem on my Galaxy Nexus. Thanks for any input.
Have you tried CPU Spy? Mine shows deep sleep when the screen is off. Also screen is the biggest battery user, by far.
Yeah. I used it and it said that it spent 2 hours at 1000mhz (amount of time the screen was on) and 12 hours at 216mhz and 76 hours in deep sleep. That 12 hours is taken by Android OS, and I don't know why. It is killing my battery. Does anyone know why Android OS is staying awake so much?
It is probably apps that are trying to sync. See what you have that might be trying to update/sync.
You also may want to try uninstalling some older applications. I think I read somewhere that some older non-ICS optimized apps can prevent the OS from sleeping.

Just wipe your system clean and reinstall your apps. That will fix all your ICS upgrade issues.
Are you syncing email via activesync? If so, turn it off for a while and check if it makes a difference. This is what makes android os go through the roof for me on the tablet and the phone!

Is that 120 downloaded apps or 120 altogether (including system apps)? Either way, disabling auto-sync and background data before putting your Xoom down could/should help curb the excess battery drain. The only issue with that is certain apps, like Market, won't function without background data enabled but that shouldn't be an issue if you won't be using your Xoom for a while. You could search the forums or Google on how to create scripts to disable/enable background data and auto-sync for you when you put the device to sleep and wake it back up, respectively. Or just search the Market for an app that does that for you.
Do you leave your wireless radios on (wifi, bluetooth, etc.) while not using your Xoom? Setting wifi to disconnect while sleep may also help.
Thank you all for your input, however I think many people do not understand what I am saying...
I understand how to reduce battery drain IN GENERAL, what I am asking is, are people seeing battery drain faster overall on ICS compared to HC? I am, and I think that Android OS is the culprit. Is anyone else experiencing this?
Thanks!
You know, I had the same exact problem when I installed the first fully functional EOS ICS rom for my Verizon Xoom. The Android OS kept draining the hell out of my battery. I went from having about 5 days of battery life to 1 or two tops.
I decided to try a different rom. Since I don't have Mobile Internet, I decided to experiment and installed the Wingray Version of the CM9 ICS Leak(Kang) and I haven't had this issue since.
So I'm not sure what fixed it, was it because I tried a different type of rom, or was it because I downloaded the Wingray version? Not sure, but either way the problem stopped.
Perhaps try a different rom if you're rooted?
I am experience this issue on my Nexus. Try using easy batter saver. It extends my battery life very well.

I'm not, if anything ICS is giving me better battery life than HC. Even considering I'm now overclocked and using my Xoom a lot more.
I think a lot of people misinterpret the battery % used though. Just because something is using a higher percent of battery does not mean its sucking your battery down, there will always be something at top of that % list, it doesn't mean there's a problem. It's a relative list. It's entirely possible (and reasonable IMO) to have Android OS at the top of your list if you've used your device for only 2 hours over 3 days! You barely used it, what would you expect to be at the top?
that's a known problem,
Android OS is also taking up a lot in the stats for e.g. the Galaxy S on its ICS port
a related question though:
I'm mainly using my Xoom for ebook reading (PDFs via ezPDF and/or repligo reader) - which ROM in your opinion offers the better battery runtime
Team Eos ICS ROM
or
the Team Tiamat Moray ROM
?
Many thanks in advance !
Android OS battery bug 4.0.3
If your android device has been off for a considerable amount of time, Android os should not be at the top of battery usage list; phone idle would be in that spot under normal situation. However, there is a battery bug in 4.0.3. After installing 4.0.4 on my Gnex it fixed the problem (from my understanding 4.0.4 was only for the Gnex as its a newer device and the Xoom wifi is slowly becoming obsolete). I'm guessing this will be fixed in 4.0.5 that will be released sooner or later... my guess is later with aging devices.
My Wifi only Xoom with Team EOS is getting 4+ days of battery life and my screen is whats taking most of the battery. I am using the latest nightly as well as the latest GAPPs. There is something running on your Tablet that is casing the problem you are having. I am having no probles with ICS at all and having great battery life. Have you tryed using maybe setcpu to setup a screen off profle. I would maybe think about doing a full wipe and starting over with the latest of everything.
My android OS was at the top of my battery usage (74%) even when in sleep mode. I used to get 5-6 days, now I get only 2 at best.
I disabled wireless and the drain goes away, android os goes back down to 2-3%.
Any ideas?
ICS 4.04 Xoom WiFi only.
Thanks

Thank you all for your input, however I think many people do not understand what I am saying...
I understand how to reduce battery drain IN GENERAL, what I am asking is, are people seeing battery drain faster overall on ICS compared to HC? I am, and I think that Android OS is the culprit. Is anyone else experiencing this?
Thanks!

mine is draining somewhat fast when i use wireless, but as soon as thats disabled im good to go
so I've been bouncing back and forth between 2.3.3 roms and CM7 based roms lately and one thing I've noticed is that on all the cm roms I've used the battery seems to drain really fast while using the phone (web browsing, texting, anything basically with the screen on) compared to stock based roms. I can litteraly watch my battery % drop while I use it. I've tried various kernels, oc/UV, keeping screen brightness low, none shows too much improvement.is this a known issue or is it just my phone?
It could be just your phone. I'd say completely wipe your phone, and reinstall everything. If it doesn't help, then it might be the battery. But I would usually (with CM7 and Faux's DS kernel) average around 12 hours.
I'd also say give an ICS rom a try, I average around fifteen hours moderate to heavy use.

Freeze all apps you don't use or need... But I always got horrible battery life regardless.

I did that too. I actually uninstalled pretty much every app I didn't use regularly and any stock replacement apps like yahoo mail app, swiftkey x, and a few others... but it didn't make a difference. my drain isn't too bad in standby, about 1% per hour, its when I'm using the phone. for example, say my phones fully charged, if I unplug it and surf the web, go on xda app, Facebook, and play a couple rounds of Scramble w/ Friends for lets say an hour straight, ill be at probably 40% left or less when done. on a stock based rom I'd say I'd probably be around 60% or more left. I'd stick with 2.3.3 if the camera wasn't so crappy but I take a lot of pics so no go.

yea I almost always do clean installs so maybe my battery's shot, probably gonna order an anker battery here soon. been holding off on ics till the bugs get ironed out but looks like a lot of progress is being made so gonna be giving that a shot too

Ive noticed this too. i have great battery life on any 2.3.3 any other roms seem to drain pretty fast. However i was able to tinker with some custom kernals (faux and morfics) and get the battery life to be noticably better on 2.3.7 roms like Singh,EB,CM7 etc. Bigger battery helped alot too. i use the Gorilla Gadgets 3500 mah. at least 2x more battery life than before easy.
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

Really? I got faaar better battery life on Scott's Paranoid Android ICS build than I EVER did for any Gingerbread rom...
Honestly, I don't even remember by now
I have never payed that much attention to battery life..
usually lasts all day for me on JB, that's all I need
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.

Yup, it's all been the same since ICS, I absolutely cannot get acceptable battery life, no matter what i do.

are you getting AOS drain while on wifi?
you may consider a factory reset and sdcard format
when you reinstall, decline all google locations and backup services.

I have done a factory reset, i formatted my sd card not too long ago (I also suspected this)
I also make sure google locations is disabled, never keep backup enabled (i did once by mistake and the auto restore nearly killed all my monthly data)
I am going to toggle wifi tonight and set a marker in BBS, i'll check the drain overnight (I did this a while ago and it did improve standby drain somewhat, but I am going to try it again)

i do notice battery drain in some areas. but not others. some people seem to think certain modems are effecting the cell standby drain, not sure myself. but there are many compatible modem.bins to try from att and t-mobile(t959v)
Just an update: wifi didn't help much.

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.
There are a few battery thread that may be helpful if you havent looked:

This is true, and you can save battery life w/ customization and now Scott is up to JB being one of the best battery life roms I've run
or just turn down your screen brightness
