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.

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.

Do you know of any that are especially problematic?
I have 120 apps. Isolating the problem is going to prove to be difficult. Any ideas which ones? This has been happening with my Nexus for 3 weeks now, nobody else is seeing Android OS taking up a lot of awake time?

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 seeing some of the same issues on EoS nightly 49. I'm down to 88 percent with barely any use. 14 hours of up time. Android OS at 3hrs and 27 mins up time.

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
Bruce

Hello,
I can't post in the BlindIce topic so I hope it's fine here.
I've seen only good reviews about the battery, that's the main reason I installed this ROM, but I seem to have a problem, my battery drops like crazy. In ~2h it already went down to 86%, and all I did was send 2 SMS. On Endymion I didn't have this problem.
And I also have a problem with the stock browser, it's moving like a snail, but the main problem is the battery, firefox/chromw is working fine so I can live with that.
I'll upload the battery log after I get home, if needed.
Sent from my Desire S using XDA
i was also very happy with it despite minor bugs but eventually many things sent me back to endymion i can guarantee pretty soon you'll be back on endy, ics roms are nice but until the kernel comes out there isnt really one that can rival endy
anyway back on topic, check things like widgets? especially things like youtube widget i just took mine off, having it there means its connected to the net cycling through the subscriptions constantly, thats an example most widgets add to drain quite well, check your syncs, which app syncing for how long, can you do it manually etc, weather apps are they syncing to frequently, which apps are using location? using better battery stats i found google locations is used in many things without me even knowing, all of these things should be checked and configured on any rom, there is nothing really specific, maybe your 3g is using up the battery? try switching to gsm only.. finally have you calibrated the battery or more specifically the phone; so it reads the battery accurately.. thats all the things i can think of off head to help
Thanks for your reply.
Anyway, all the config was done and there was no widget running so I guess it was something with the kernel/ROM that my phone didn't like, considering that I'm probably among the few or the only one which had such an issue.
And like 3h ago the battery was hot as hell for no reason, only Y!M was running, it literally burned my hand, there's still a little red spot, so idk what was the reason or what happend but I went back to endy, after the 3.0 kernel will be out, I'll try again, until then thanks and keep up the good work @devs.

Any widgets (or sync's) running on your phone?
If so - how many and what kind?
The battery isn't that bad for me but on all of the ICS ROM's that I've used the battery drain issue is quite bad. Then again, I was using Virtuous Affinity for a while and the battery wasn't brilliant on that either so I've come to the conclusion that I will probably require a new battery soon.
But still, the battery on my phone on BlindICE has been better than on yours but I'm reluctant to switching from it now
Hi all, just got my 11yr old son a ChaCha. He wanted a Blackberry for the keyboard, but managed to persuade him to have the ChaCha. Anyway, it seems to have this infamous dialer bug.From reading throu the forums, am I right in thinking that if I put a custom rom on, it will get rid of the dialer bug? He curently takes it to school, at 100% power, and generally comes home with the phone on around 10-20% power!! He is only allowed to use it at break and lunchtime!! Also, as it's for my kid, I would like it to be as close to stock as possible. Any recommendations? As I already own a customised Desire, I am happy to 'play about'. I have already unlocked the bootloader, and rooted, so that I can use link2sd. Without that he could only install 3 apps on it before it got the low disk space warning!! And as he's only 11, he likes to put a lot of junk on his phone!! Any help would be most appreacited. Thanks.
Like I mentioned here, I don't think that the dialer bug really exists. It's just the battery statistics that are not very clear.
The overall battery performance of the Chacha is very bad, so if you play some games they could drown the battery within an hour. There only thing you could do is rooting the phone and using another ROM. You can win a little with this, but for playing games, Chacha has a very bad battery performance.
Best performance was with CM7 - there my battery live was 1 1/2 days (without playing games), with CM9 now it's less then a day again.
So for better battery performance and keyboard I guess the Motorola Pro is the only phone, or non-Android phones.
I agree. There is no dialer bug. Those are many processes that show as Dialer. I don't mean to offend you, but have you considered that your son is using the phone not just at break and lunchtime? It is hard to resist, especially when it comes to new things. You should test it yourself and see if battery drains that much in that specific time frame.
Regards
Custom ROM would be a good option, but as he's 11, he's probably not old enough to appreciate the faster speed of CM7 or CM9, over his front camera. I'm guessing he'd want his front camera to keep on working lol
But when I was using the stock rom, I just turned my 3G data off whenever I was not using it, and that makes the battery last miles longer
For easyness (lazyness). Create a widget on the homescreen, under Settings and Mobile Internet. And then you'll have a widget you can just tap to turn on and off the mobile data as long as your son can get the hang off turning it off when he's not using it, then that should work a treat
go for CM Roms
IMHO I do believe that there's a dialer bug in stock Chacha, I think it is caused by the dialer's continuous polling of the proximity sensor (this bug has been reported in a lot of htc stock gingerbread phones, the app dx battery helped me confirm this.) Custom ROMs helped me solved this bug but only those that are CM-based (stock-based roms still has the dialer bug). CM7 is very stable and has the best battery life for any Chacha ROM but CM9 just looks so damn good and the battery life is still way better than stock (in stock, I get battery drains even if my phone is just idle, wifi off)
Thanks for the advice guys. I think we will leave it a couple of weeks and see how it goes. May end up putting CM7 on it at some stage, as I have a CM7 based ROM on my desire. He is only allowed to use it between lessons, otherwise it's detention!! He also uses it to listen to music to and from school. And yes, I have notice that the battery goes down rather quickly, when I was setting it up for him.
Well, there sure is a bug in the stock rom that drains it within hours. IMO it's coming from the 3G connection... Sometimes, when my coworkers drive me crazy, I turn off the 3G... I live in a neighbourhood with a bad network connection, this means that it is reconnecting all the time. My battery normally went for about 15 hours, with 3G off it works for over 20 hours. But since I've installed CM9 it stays alive for over 40 hours...

Does anyone have any of the AOSP roms that run well on their phone.
As far as wakelocks and getting the phone to properly sleep. I know some people have suggested to get this experience, you have to change settings and not use certain apps, etc...
Is there a rom out there thats not sense that will allow the phone to sleep to get good battery life, etc??
I love pure android and I love this phone, but I have tried and tried and I cant find a rom / kernel combo that meets this need.
If you have success with this phone and an aosp rom, please share so I can try it out...I really want to get away from sense.
What keeps me on sense is the ability to very easily make it though a day on a charge and the camera. The new 4.2 camera is a huge upgrade that "almost" nullifies that area, but the phone constantly waking up and battery life draining 10-14% overnight while the screen is off kills me.

Download the Better Battery Stats, I'll know more info from that and will be able to help you.
Yeah i agree. Its a great app. For me this is what helped:
Disabling notifications and auto refresh on Facebook. Disabling location reporting etc in Google maps.
Battery drain is still worse than on Sense but wakelocks have been seriously minimised.
