Unhappy with your battery life? Fix is here!

Hi everyone,
I have had my Galaxy S for a month now, I have been very unhappy with my battery life, so I thought, I gotta to fix without compromising perfomance.
I found it!
My battery life during this 1 month period was utter crap, battery used drained from 100% in about 10-12 hours on average.
At the time I was running the latest FWs (I kept updating as the FWs came out) with Mimocans EXT4 fix.
I was with lowest brightness setting, running on 2G without any screen animations.
So heres the fix:
Install SetCPU 2.02, make sure to apply on boot, make the minimum speed 100mhz and the top 800mhz.
This ensures the phone doesn't ever go to 1ghz but that the performance is never compromised (even when playing games, videos, apps).
Because I have the Mimocans fix, everything is smooth and battery life goes down very slowly!
Heres the stats of my battery right now:
Battery Level 70%
21h 40m 25s secs since unplugged
Display 37%
Phone Idle 27%
Cell standby 21%
Voice calls 7%
Android System 4%
Internet 2%
Android OS 2%
You can give this guide a go, sorry if it doesn't work, just trying to help.
Regards,
Azazin!

Please update with display time, phone idle time, standby time and voice call time. Without it these are a bit useless, these don't seem far from my stats when I use the display for +/- 1 hour.

I have the percentages up in the OP.
This guide isn't just for turning crap battery life to good, it's also for people to extend their battery life if they already have a decent one.
Following the underclock to 800mhz my phone can last this long, compared to before when it used to last 10-12 hours with same usage!

The percentages stand out, thanks, I saw them. Again, they are a bit meaningless without the time used. If you don't use your phone for 24 hours you should lose maybe 5% with sync off.
So, please, click on "display" and report the time that the display has been on, repeat for the other usage categories, other people will ask for this same information. I don't know if you didn't know how to do that or if you are witholding the information, hopefully it's just the former. I understand that, perhaps, you are doubling your battery life, but depending on the way we use our phones, relative to the way you use your phone we can see better or worse results. Doing this will allow us to know how much you use your phone and for what purpose, so we can make personal judgments about its merits to our usage.
TIA

This may fix the issue but it's merely a patch to cover up the wound. From my experiments I've found that in most cases the problems are related to the phone never entering sleep-mode. If you have bad battery life, please do the following:
0. Make sure you phone has been running on battery power for a while, usually a day with only 20% battery left is a good place.
1. Type *#*#4636#*#*
2. Go to Battery History
3. Other usage and "Since last unplugged"
4. Check the "Running" bar. Generally, if this is over 60% something is wrong.
5. Go to partial wake
6. Check if there's some application (e.g. Facebook) that has a high partial wake percentage. This is bad. System should be on top on most systems.
So, do you have the signs of something being wrong? Fear not! Usually this is due to a program or service misbehaving. I had bismal battery life (about 15 hours, just check the other thread for several of my posts), and then I uninstalled "Weather from Yr". I also let my phone discharge completely, then charge TURNED OFF over night. I then disabled auto brightness and "power saving" in the display. Yes, I disabled the power saving feature, and my battery life went sky high. Now I have about 2 days of moderate use (1h 30 min on) and about 1 day with heavy use. Letting any application run while the screen is off using partial wake KILLS my battery.
Unfortunatley, I didn't follow proper scientific approach when conducting my experiments, so I can't say which of the three things (uninstall weather from yr, complete discharge/charge cycle or turning off power saving) that did it for me, but it's worth a shot if you haven't rooted your phone. Post back with results.

Hi,
Oh okay lol, no problem.
Display: 1h 22m 8s.
Phone idle: 20h 51m 22s
Cell standby: 12h 12m 52s
It doesn't look like I have used it much but during the time the display has been on, I have either been:
Playing games,
Texting,
Twitter,
Or Internet.
It doesn't look like much, but I recommend you try this and post results before and after

2 things:
1) the phone number thing is pretty cool, in the past I've used "Spare Parts" for identical and a bit more information. I encourage people to use one or the other.
2) You can still fix the unscientific nature of your experiment by a factor of 1/3. You can turn power saving back on, and I'll try it. Also, I'll assume that 1 charge wouldn't make a world of difference, so I think that could've added a few minutes to your phone life (more than charging with the phone on) but maybe someone with actual technical knowledge can chime in.
As for any program running in the background, I had a similar situation where I was going from losing about 30% in a day, similar to the OP, while using the phone, and hence the display, for about an hour at work. I also, always preferred to leave the phone off the charger overnight, so I'd have been unplugged for 16+ hours. One day I allowed 3 things to run to check both battery and 3G usage (I have 500mb per month until I decide to change my plan, probably waiting for the new deal thats been announced for unlimited data for an extra 10 bucks sometime this month). So, I ran:
Sync
3G data monitor (To test if I would go over what I'd use too much data from my allotment, refresh every 30 mins IIRC)
ATK (to kill tasks, hoping they'd use less of my precious bandwidth)
This 2 tasks plus sync just CRUSHED my battery, by the first time I turned on the screen I saw more than 50% drain from my battery, probably around lunchtime (probably 3.5 hours from the start of work). I turned off all 3 and, like you, I haven't conducted a scientific experiment since.

I tried something similar with overclock widget, but I had the impression that underclocking made the SGS really unstable. It freezed completely like 3-4 times a day. After uninstalling overclockwidget the device didn't crash anymore.
So how are the longterm effects (say, 1 week) of setcpu?

If anything I'd OC my phone, not the other way around.

The software probably isn't optimized for your usage scenario, I don't think an underclock, if done right, should be that bad, OC on the other hand...

I'm in the same boat, screen uses 80%+ of battery when the screen is on, as long as I'm not wasting battery when the screen is off and processes aren't running I have excess battery life, not to mention a spare battery, which I'd like to get more use out of if I could better my experience.

Battery Life: desperate for help

Hey,
I know there are a lot of threads about this topic, and I've read a lot of them on my quest to improve my batterylife. I've come from 4-5% usage in sleep down to 2%, but i still think its to much, and could use some assistance.
Like I said, I read a lot of threads discussing this matter but I would like for someone with a little more experience to take a look at the data and tell me what you think.
so here are some screenshots which I dont understand completely.
So what I dont understand is, cpuspy says, 84% of the time my phone was in deep sleep, but the batteryuseage shows something completly different. it shows the phone has been awake almost the whole time.
but if i'm reading BBS correctly there are no mayor wakelocks occurring.
i looked at my battery before i went to bed last night. it was at 59%. exactly 10 hours later when i woke up, it was at 40%. that means it lost almost 2% an hour when i didnt touch the phone once.
so i know stuff like BLN sucks juice, but i havent gotten a notification last night, and i set a schedule for BLN to turn off turing sleeping hours. and it only blinks for 10 minutes after a new notification has arrived and then stops.
i undervolted the CPU a bit (75mV on every speed).
i calibrated the battery (drained completely, removed for 2 minutes, charged to full while phone was off, at 100% removed it again for 2 minutes, put it back in and booted phone)
i wiped the battery stats
turned off a bunch of stuff, like autoupdate on market and other tips i found here on the forum.
wifi sleep policy is set to when screen turns off (btw. sometimes i doenst reconnect after the phone wakes from sleep, anyone got an idea how to fix that?
i'm running galnet miui with the siyahs 2.3 kernel and the KI4 modem.
now the question is, where does that leave me? what am i missing here?

For one day see what your battery life is like when you COMPLETELY disable BLN. Titanium freeze it or uninstall it. Second screenshot, what is that Imapfolders things? It has a high count (I see 1200), maybe try disabling that for a day just to make sure its not an app acting rogue. Another thing, have you disabled samsung bloatware (IM app, social hub, game hub etc).

Most of your wakelocks are radio related. When the phone gets a data request and wakes up to handle it.
I suspect its the K9 push email account that is doing it - anyway to change that?

adding on these questions that i also faced by the thread starter, how does this affect:
AlarmManager
Android System
40s(40s) Count 2336 0.1%
i believe this might be the contributor to the constant phone wakes?

would forwarding my mail to gmail and then getting it pushed from there be better?

from what I've seen on here gmail causes bigger wakelocks. most people recommend using K9. Maybe try a different rom? sounds like a big move however I do know that when running the hyperdroid rom for example most people get amazing battery life. Seen a few nice battery reports with checkrom also

I can confirm battery life on Check Rom coupled with Siyah 2.3 is excellent.
I might be stating the obvious to the OP but have you frozen most of the bloatware in Titanium Backup, ever since i done this battery life has improved substantially.
Also go into Wi-Fi settings > Wi-Fi sleep policy and ensure it is unticked,choose one of the other 2 options
In location and security untick Use GPS Satellites as this will use up lots of battery when it's ticked.
In the Privacy tab untick back up my data as this too will cause battery drainage.
Lots and lots more battery saving ideas, search and you'll find them

well i really like miui so i dont think i'll switch just yet. i'll leave that as a last resort.
i see my mistake here, i should rather be looking at the wakelock count rather than the time correct? K-9 sure as hell has a lot of wakelocks. (counting all wakelocks mentioning K-9, i get more than 8000)
the problem is, my email provider doesnt support push, only imap idle, that must be the reason why its wakeing the phone up so often. although i didnt get any mail last night...
from my understanding push services work a little different, since the app using it doesnt have to be connected the whole time. it gets woken up when the server sends a new message.
i deleted k-9 for now, and i'll see how that reflects on my battery life.
would maybe polling mail every hour be better than using imap idle?
work related i really need a way to get my mail frequently.

have done all of that already, like i said, i've read a lot on the forums (cause i myself hate ppl asking the obvious they could've found out by using search for 2 minutes) but thanks for the tips.
only thing i'm not so sure about is the bloatware. since i dont think miui has a lot of that. but i'll look into that.
thanks for all the help so far.
i'll try to look at wakelock count more than on time.
one really anoying thing is BBS force closes A LOT on miui rom. at least i think its rom related, since i didnt have these problems with the other roms i tested since i got the phone.

Hey Phoboss,
please consider the rom is almost non relevant (except eye candy) to battery drain, the kernel makes the difference! I was on Siyah until three days ago with a consumption of 10% in 8 hours during normal usage of the phone, but then i found this Thread, give it a try (i use extreme edition w/o ans probs) forget about setcpu, if the kernel was compiled right, u dont need it!
Furthermore, why do you replicate so many folders in K9, from my POV the Inbox should be sufficient, but I dont know ur provider, push works fine with GMX, even on a freemail acount
If you want to try more, freeze the Calendar App and choose an alternative, from what I have heard, this helps to get rid of most of alarmmanager wakelogs (to be confirmed).
BTW, im on 75% Battery left right now after 20! hours on Battery with moderate usage (some WIFI, lots of XDA App , some calls and browsing, most on 3G which is always on)

Good Luck!

Does your carrier support Fast Dormancy? Because you can turn that off as well to save a few % batterly life if it's not supported. There's usually a phone/model specific code you can type into the dial pad to switch it on/off (I can't remember off the top of my head what the code is but if you search around you'll find it for the SGS2).

Thanks for the tips, I'll look into that.
Here's a little update from last night. Was sleeping for pretty much exactly 8 hours and lost 8% battery in that time. So I came down from 2% an hour to 1%. Still think that's to much though.
The thing is, in the 40 minutes I'm awake now, I've been using tapatalk and surfed the web and I lost another 5% in that time.
This can't be normal can it?
Battery usage is still showing that the phone has been awake the whole night. As you can see on the screenshot below, between 0:00 and 8:00 I was asleep, screen and WiFi where off the whole time, but the phone is shown as awake. I've attached another bunch of BBS stats, this time sorted by count and not time.
(btw. how do you get BBS to show a graph like on your screenshot karpfenhai?)
And isnt Siyahs kernel considered one of the better ones around? Just curious.
Fast Dormancy is not supported by my operator, BUT I've read that it doesn't matter because my operator propagates that to the phones, and they disable it themselves.
Regarding K-9 checking so many folders, that's because I have them sorted by server side rules. I guess I could limit that to work mails.
Thanks again for the help so far.

I used Siyahs kernel for a while and I loved some of the features but Speedmod has it beat in terms of speed (duh! ) and battery life (I had read that multiple times which made me switch and I noticed a drop in battery consumption when switching to Speedmod).
You can check if FD is off as well but if your carrier doesn't support it may as well switch it off rather than relying on the phone to do it for you (I'd read a fair few posts from my fellow Aussies recommending switching off FD because AFAIK none of our carriers support it and it's a battery drain).
BTW - regarding Wifi sleep policy, I've seen people DEMAND that you completely turn off sleep policy as it's a battery drain (like you, i've been doing lots of battery reading and got mine down to very low consumption thankfully) - try comparing BBS with sleep policy on screen off vs sleep policy off and actually switching wifi off completely overnight.
Also, one thing I found useful was using titanium backup to completely freeze apps I wasn't using rather than just relying on the individual app settings. This also helps because it stops them booting when you start up your phone. Speaking of which, get Startup Manager if you haven't already - just like your home pc: turn off everything you don't need
EDIT: my uni mate wrote a pretty good general guide (for installing custom roms/etc as well as batter life tips) that might help you: http://forum.xda-developers.com/showthread.php?t=1351663

1% an hour is very good pretty much what i get you cant really get much better than than unless you switch off data and sync and most other things, consider yourself lucky you only lost 1% an hour, if your surfing the web for about 40 mins non stop 5% sounds about right too.

Hello again, it seems you are on the right track, go ahead, its getting better
I had the same issue, 2ma consumption for 3-4 hours after unplugging, then it raised to 14-18ma for no reason, my suspicon was the accu wheather widget, but I didnt do any further investigation cuz I switched the kernel and the issue dissappeared, yay
Bbs can provide some more infos even on alarms, check it:
I still have 35% left and I can leave the house w/o getting panic ;-)
Try the kernel I mentioned earlier, you can only win!

BBS is force closing like crazy, cant really use it a lot.
the thing is, i still dont have an idea why my phone is always shown as awake. the one time i could access the graphs within BBS it showed the same behaviour. phone was/is awake the whole time.

As far as I know, this is related to miui, I've seen other users using this rom complaining about fc's..
Search for logcat and do a manual dump to gain the desired data.
Sent from my GT-I9100 using XDA App

I wonder if that constant awake bar is something to do with MIUI - certainly 8% in 8 hours drain isn't constantly awake, it would have drained more.
I route all my email to my Gmail and push that - doesn't seem to give me any battery trouble! I don't know if its a good option for you, or really whether or not its battery efficient, I just really like the Gmail interface.

so i've frozen some apps, wiped dalvik and cache partitions
but unfortunately that didnt really help.
here are some more screenshots (i resetted the data to get a more accurate reading) from the last half hour, during which, as you can see by the screen on time, i havent used the phone.
so do you think its odd that my phone got woken so often during this short time, or am i just to anal about it?

Simple can work well

Just to back this up im running Hyerdroid just checked been running 20hr 15min and on 83% but dont do any fancy stuff just charge the phone when it needs it

like your battery saving method , but it doesnt help you, if your phone dies during a work day. all the testing i did was basically lab tests, i never really used the phone much during this time. if i start getting calls and writing mails all day, the battery will die, thats why i need to find out whats going on.
i just want to know, if what i'm seeing on the first screenshot in my last post is normal or not. from my understanding its just a little odd that, in the approx. 30 minutes that are displayed, my phone was awake a lot, when the screen wasnt even on (i was under the shower and havent touched the phone ones).

Battery Drain - Again! events/0 and suspend !

Hi,
I have on my Samsung Galaxy S2 as well as on my Samsung Galaxy Note a huge battery drain caused to 2 processes : "events/0" and "suspend".
I have already read a lot of threads concerning this problem, but without finding a solution.
I found out, that I only have this bug, when activating my Wifi connection (on both devices). I tried every wifi sleep policy, still getting same results.
So finally, my Android OS battery usage is more than 50%, even more than my display.
Does anyone know a solution for this problem, considering that now I'm sure that it's linked to the wifi activation on both phones. (I did a factory reset and there was no battery drain until I activated Wifi without having any other apps installed, besides of System Panel to monitor....)
Thanks in advance,
Regards,
Ben

If your phone is rooted you should 'freeze' or remove the apps "Wifi sharing manager" and "Wifi sharing" with Titanium Backup. Fixes your Wifi-problems.
It's a service that looks for other Samsung Wifi devices constantly when Wifi is turned on, thus draining the battery.

No, my Phone isn't rooted. I was not sure if I should or not, considering the warranty problems. Is there no other way?
A lot of other users don't have this problem, I don't get why I have it-.-

As far as I know, it doesn't really void your warranty as long as you do it the right way and unroot your phone before you send it back to Samsung (if problems occur).
Someone correct me if I'm wrong.
As an alternative you can disable WiFi when you are not using it with apps like Green Power and Juice Defender (although I strongly advise Green Power for it's ease of use).

Thank you.. But there has to be another way to solve this problem, because people I know don't have this bug... without using any batterysaving software. :/

I guess it's a native issue of your device...

In the first week that I got the Note, the device is eating up about 10% of batter per hour even when idle. The way that I use this Android phone was no difference than other Android devices I have used. When checked the battery usage, I was stunt to find that the Android OS was using 90% of the battery. Funny is that the screen showed a usage of 20minutes, while the OS showed a usage of almost 3 hours.
Soon after, I decided to do a factory reset due to other reasons. Some how this problem went away and the usage is back to normal. I don't know what happened, but in my case, it solved the issue.
Also I don't use the Note as a phone, but rather as a mini-tablet when I am not at home. So I decided to put the device in Flight mode when it is not in use. In this mode, the device hardly uses any battery. For example when I went to sleep, the battery was at 79%. When I woke up 7 hours later, the battery still shows 79%.
Hope this help!

How about you stop ASS-uming about devices that you don't own. The Galaxy Note is faster, smoother, lighter, and more portible than your Motorola tablet. The only tablet that can match or even outperform the Note is the Galaxy tab so have fun with your soon to be obsolete tablet.
OT: Your issue may be fixed with a factory reset.

Did you try 'Green Power'?
Did you try the app "Green Power". It is pretty good and promising. It will turn off Wifi / 3g while it is not using, it save much power. The paid version just including the 'night' mode.

I'm suddenly facing this issue. Have had no problem with the battery so far. My battery went from 40% to 15% overnight with the screen off and wifi off. :s

Edit one more time: I found the battery draining really fast just now too: 15%-12% in about 20 minutes.
Clearing the RAM seems to have stopped that though.

I really do think it's the wi-fi sharing/manager processes. I've frozen mine to see if that makes any difference.

It's exactly the same for me, with the suspend and events/0 processes...

Any Solution

I solved my problem thanks to a tip on this forum. I just did a factory reset for my ohone, and then reflashed the firmware. Its working great now

ok, but what version?
I'd think it's pretty relevant to know what android/fw-version you're all using? I'm on Samsung's original 2.3.6 and have no issues...

No, its not. Coze I've upgraded to 2.3.6, and then downgraded to 2.3.5 again, and my problem was still there. Only a factory reset solved my problem.
By the way, u can notice something is wrong by the amount of heat generated while using the wifi, or by how slow pc usb charging could be. It even used to discharge when connected to pc!
The amount of heat was a very strong indication that there was something wrong.

Still battery drain
Hello all,
as of 26 march 2012, I still have something problematic on my samsung galaxy note. I flashed last Open German firmware (LC1) (from samfirmware). The phone is rooted, and as far as I noticed the "suspend" process is still draining the most battery compared with the display ratio. I tried to wipe everything, I downgraded back from LB1 to KKA with Odin, wiped, flashed LC1 and reinstalled onyl paid apps (i.e. not with no advertises). I turned off the Wifi but the susped is still there, eating 63% of resources.
There are not special kernel wakelocks... any ideas on how to go ahead?

I have a standard non rooted rom. I also faced sudden battery drain, but use the following solution -
Folders - keep to the application page not home screens
Backlight - off when inside, 50% if outside or on charge (auto drains faster)
Browser - use one of the low power saving mode
Screen background - live wallpaper eats battery. Use a dark based wallpaper , use much less power
With all the above battery is fine. GB 2.3.6.

I've had the exact same problem as the topic starter. Android system running over 90% in standby and suspend and events/0 running at 100%. I had this problem on stock XXLA6, on Darky V3.3 XXLA6 and Rocket V23 XXLC1 and after a number of full wipes.
My wifi wouldn't turn off in standby and setting different sleep policies didn't do a thing.
I removed the Samsung Sharing app, installed GreenPower and set it to turn off wifi and 3G/data as I don't need sync when it's in standby anyway.
All problems are gone now, after an hour in standby I still have 100% charge and after browsing for 5 minutes it lowered to 99%. Suspend and events/0 no longer run when the phone is in standby, wifi is turned off and Android System is at 4% now.

Battery troubleshooting (ROM inspecific)

This thread is to discus extremely poor battery life on the Nexus S. When we say extremely poor, we mean averaging <24 hours per charge at idle.
After much research I think it's safe to say that some of us are experiencing extremely poor or contrarily, extremely good battery life and no one seems to have an explanation. I'm hoping this thread will find the answer.
The issue:
Many NS users are experiencing extremely poor battery life regardless of:
Rom installed
Apps installed
Installation method
Battery used
Charging method/battery training
Phone usage
Power configuration/tweaks
When we say "extremely poor" we mean <24 hours at idle, but many users are getting less than 8h/C at idle.
I personally have tested this against several ROMS both GB and ICS. We all see slightly better battery performance with GB ROMS, but never greater than 24h/charge.
My ROM history:
Tested the following ROMS for 4 days each, following the same installation procedure each time.
CM7 (nightly/stable) - ~15h/[email protected]
CM9 - ~13h/[email protected]
CyberGR .v4.5 - ~11h/[email protected]
CyberGR .v5.0 - ~11h/[email protected]
Installation method:
Wipe battery stats
Wipe data/factory reset and wipe cache partition
Flash Dalvik-wiper.zip and wipe Dalvik Cache
Wipe data/factory reset and wipe cache partition again
Format /system/data/cache/boot/sdcard
Flash ROM
Flash Gapps if applicable (CyberGR comes with Gapps installed)
I was running an AUCKF1 Radio for all tests. I did try a few other radio's but did not see any noticeable increase in battery life *edit-flashed XXXKB3 and may have increased my idle time by 6x? still testing*
I've also never personally seen an NS get >24h/C, and I've deployed >40 of them to customers. I've only ever heard of >24h/C here on the forums where it seems quite common.
I've seen reports of users flashing the OTA automatically or manually, and some experience <8h/[email protected] while others see >3d/[email protected] I've also tested the OTA and never saw better than 13h/[email protected]
So, we're trying to find the common denominator between those with good battery performance vs. those with poor performance.
Suspects:
Android OS is almost always reported to be active/awake for at least 50% of the time, even at idle on a brand new clean install. It is always the highest consumer of battery, always keeps the CPU awake.
I propose the following test:
Regardless of your setup, if you are experiencing >2d/[email protected] or with use, please post the following:
Phone model (ie: i9020a, i9020t...)
ROM
Radio version
Installation method
Screenshot of your battery monitor from a full charge over a minimum of 10 hours.
Screenshot of your battery use by application/service (we notice that Android OS seems to be the culprit in most cases of poor performance)
For those getting <1d/[email protected], please do the following and then post the same as above:
Note: This should be done overnight.
Follow the above flash instructions and flash whatever ROM you please.
Reboot to recovery and wipe your battery stats.
Power off your handset and give it a full charge while powered off.
On first reboot, sign into a single Google account but do not restore your apps/backups and disable Google sync.
Do not install any additional applications.
Enable wifi/bt/gps/data/sync and associate to a wireless network
Do not modify any power settings.
Leave your handset to idle overnight for at least 8 hours without touching anything.
In the morning, take a screenshot of your battery use as well as battery use by application/service.
Post Phone model, ROM, Radio version, Carrier, and Screenshots.
I recognize that there is some argument about how fast your battery will re-train itself after wiping battery stats. In my experience the training seems to be optimal after 1 full charge to full discharge cycle, but ultimately I've never seen further training result in >24h/C. Someone please let me know if there's a more accurate way to test this? Maybe we shouldn't be wiping battery stats at all?

I'll get us started.
Sorry, didn't get screenshots after 8 hours because my battery wouldn't last that long.

Results fluctuate between ~8h/[email protected] and ~14h/[email protected]
With light to moderate use, I get 6-10h/C

Hey Ben i just did what you did in the other thread. full charge everything on kill all unneeded services.
I'll admit that i forgot to kill extra services and it plummeted my battery to 92% in about 45min. I had an "oh ****" moment and went and killed the random apps.
Im at 2 hours extra now and lost 3% only, everything still on.
So with that info i'll mention this for me would be considered heavy usage. I'll never have everything on constantly. When I was posting up my results of light usage and getting 3 days - note that i had everything firewalled while on 3G except for my emails and messaging and took a few calls only. everything else was off.
I'm gonna guess that with it all on and actually using the phone i'll hit at most 10 hours, probably not even that.
So that basically puts us about even. I'm curious if you do my light tests...will you be seeing 3 days also ? If yes then we can rule out models basically.

Flashed XXXKB3, factory reset (according to OP instructions), flashed CyberGR .v5 again, signed into one Google account, disabled Google sync+backup, enabled and connected to wifi, bt/gps/everything on, then left my phone overnight. Results.
Looks ****in' Gooood. 1.2%/[email protected] draw.
But then, opened my screen once, played some tunes through BT to my truck, drove around for 13 minutes, went back in the house and left the phone idling again and look at the drop! It's continued to draw like this all day now, just idling. I've done NOTHING but play 13 minutes of music and then back to idle.
What's DOES IT MEAN??!!
So I rebooted my phone and let it idle again without touching anything, and still seeing the wicked battery draw. I dunno wtf to think here, and I can't get the draw back down to 1%/[email protected]
*edit* For the sake of 100% transparency, while the phone was idling at 1%/h overnight, I was far enough away from the wifi AP i'd associtated to, that it MAY have lost signal and given up, so perhaps the wifi hardware finally went to sleep. Does anyone know if wpa_supplicant (or whatever controls wifi in Android) runs is represented by AndroidOS?
Sent from my Nexus S using XDA App

Oh. Dur...
I think that may be it. Wifi was probably dis-associated overnight. You can see at the very beginning of the battery recording, there's a sharp dip in charge for about 15 minutes, which corresponds directly to Wifi association, then the draw goes nearly flat (1%/h) for 10.5 hours and the Wifi is not associated.
Testing now... Leaving Wifi on, but dis-associated. See if that nice flat line comes back.

This is a normal night of going out, connecting with friends, a bit of music before. A weekend for when it is most important, these are the results. I forgot to photo the android os but it said it was awake, cpu for 4 hrs.

Regarding the Android OS being highest battery consumer, it might be false alarm:
http://forum.xda-developers.com/showthread.php?t=1456265
Although still, that hasn't explained the high drain (<10h/day) you're experiencing.
In your first set of screencaps (the 2h30m one) it seems obvious that the culprit is Mediaserver and Google+? One of the most annoying things about ICS that I found is that after flashing ROMs or kernels, Google-Photos have a tendency to enable sync behind our backs. Someone in my local forum discovered when he logged in G+ in his PC that the pictures in his Nexus S had suddenly shown up in the G+ account even though he never uploaded them there. After he disabled that sync, his battery life improved. As a result, I've grown OCD about checking my sync settings every once in a while. The Google-Photos option doesn't always show right away when we set up a new Google account.

Phone model and radio?

I'm back to 1%/[email protected] with everything but wifi enabled.
All sync settings enabled with no sync delay.
G+/data/gallery sync all enabled for 3 accounts. Receiving about 30 emails in 14.5 hours overnight. This should work out to 111h/[email protected]
The question here for me is that I thought Wifi would use less power than 3G given it's such lower range. I thought that when Wifi was associated that your 3G would automatically disconnect, thus using less power when associated to a Wifi AP than when connected to 3G.
Am I mistaken in this? Is this not the desired operation?
*edit* It may be looking like my draw increased by about 8x as soon as I opened the screen for the first time this morning, and hasn't dropped back down to the 1%/h. Right now it seems to be at about 10%/h again, though I'll report back on this later today.

I'm getting the same...
power drain increases for dunno whatever reason...
right after a reboot it goes ok if I do not touch it... as soon (or five minutes later) as I start playing with it the power drain increases a lot and android OS takes over any other service...
generally to test I wipe the battery stats before booting from recovery...
maybe we should check in logcat what trigger the high android OS usage?

I've checked logcat/dmesg and haven't seen anything super suspect (to my somewhat untrained Android eyes). I have done a tonne of power management scripting/troubleshooting in laptops and other mobile devices but this is really my first serious foray into Android PM, so I may be missing something.

As I said, stock settings from CyberGR .v5. Signed in to all three Google accounts and left sync enabled. Turned off Wifi but left everything else enabled.
Drove around (phone paired to my truck for music) for a few hours today, light/moderate use, and I'm currently sitting at 69% battery remaining, coming up on 24 hours on battery. Realistically, this is probably a little lighter use than normal for me, plus I usually plug in when I'm in the Jeep as I'm running not only music over BT to my Jeep, but also streaming OBDii data from my ECU to Torque (and my screen is usually on full time while driving as I like to keep track of my mileage (troubleshooting fuel efficiency as well ).
So all said, stock settings with CyberGr, Radio XXXKB3, Wifi off, everything else on, and I should easily get 2 full days of light use.
Now that said, I'm still waiting for someone getting 3-5 days to chime in. I still feel something isn't quite right.

Wow. Practically the same as myself but my battery is now around 6-7 hrs before I need a charge. I will have to buy a new battery and see if that is the culprit. Over even just flash CM9 instead, who knows..

I doubt it's a bad battery. You're seeing the same life I was before I flashed the XXXKB3 radio and re-installed the ROM properly. Follow the installation instructions from the OP and see if that solves your problem.

After looking at an earlier shot here I notice my android os stays on most of the time hence my bad battery. How do I get it to sleep?

So does mine, but it is not an accurate reflection of battery drain, per android engineer Dianne Hackborn. Look at the Android OS percentage in my screen shots - it doesn't matter.

For those with excessive battery drain: install Battery Monitor Widget and Better Battery Stats from the market. Those two apps should provide all the data you need to troubleshoot poor performance.
Also, check your signal strength. Weak reception will drain your battery in a hurry.

Sudden battery drain & hot phone; CM7, CM9

In general, the battery is very good on the Galaxy S.
But, I have been having a strange battery problem since CM7:

From times provided, there is a 14% loss in battery in 37mins 38secs, which gives a battery drain of 22.3% per hour.
The phone would last less than 4.5 hours.
You can see that the phone is not being used from the Screen On bar. The phone was simply sitting on my desk at work.
Normal usage drain would suggest less than 10% per hour.
***
Now, I have always assumed it was a CyanogenMod bug. But recently found out that a friend's Nexus S (stock everything; 4.0.4) also suffers from a bug with the same outcome. I have an inkling that the problem may be Android based, but I have no way to be sure.
Is this a CyanogenMod problem? Could it be an Android bug?
Is the problem isolated to the Galaxy S and Nexus S?
For a while, I thought that toggling Airplane Mode will halt the quick battery drain. However now, I'm pretty sure that it has no effect.
***
I have tried aLogcat, hoping to see one process getting hammered repeatedly but there doesnt seem to be anything suspicious happening.
Is there anything I can do to see what the problem might be?
Are there any other apps that could reveal the problem?
I haven't yet found an official bug post similar to this yet, so please post it if you find anything similar. (Posts like "OMGz batry porblems!" dont really count)
***
Lastly, before anyone blames me for downloading crappy apps which have caused the problem, I only have 35 installed apps, and I stick to the popular ones: AirDroid, aLogcat, Angry Birds Space, Barcode Scanner, BBC News, Chrome Beta, ES File Explorer, Facebook, GMail, Google Finance, Google Goggles, Google +, Instagram etc...
The less popular ones are: Ice Cream Sandwich Clock, Shareprice
Thanks! Hopefully, we can get this issue sorted.

Never heard of that problem before. You should look if it also appears on stock ROMs and on CM without any apps(only the one you really need. But I guess it's a hardware issue.

Is it just me or does your mobile network signal show a weak signal whenever your battery starts to die?

It could be many things...but I'd be suspicious of apps... Facebook transfers a lot of data in the background for example and I'm not even sure they updated for ICS yet.
I'd try logging out of those apps before you get to that level of battery drain and see if it still happens.

Same Issue
I have the same issue. The phone is not in a case while charging. The metal plates that keep the SIM card and the SD card get very hot to the touch. Sometimes the battery percentage gets stuck, so I have to let it cool down before continuing to charge.
Does anyone a way to fix this?

When using the phone you would expect the battery to drain faster.
Try to take a larger percentage loss over a longer period of time; it isnt very accurate using tiny numbers.
My phone was more or less idle for the duration of 22% loss per hour (you can see when the screen was on via the relevant bar).

I have the same problem too.
I don't know why. It's just have battery drain and hot with cm9 or miui.

Yes exactly. The phone begins polling the mobile 2/3G network and begins sucking power. I'm not sure how or why that would cause such drastic drops in battery but the graph seems to suggest that they are connected in some way. Data is known to drain power and if the system is repeatedly attempting to connect to mobile data while the signal is weak it may take more resources.
I could definitely be wrong here. Just an observation.

I also have a pair of Anker 1,800mAh batteries, plus the original 1,500mAh Samsung one and they are all draining really fast on both HSDPA/3G and 2G networks. Under WiFi it drains a bit slower. About 1% every 5 - 8 minutes or so (with screen always on as well). I live in Brazil and I use TIM 3G+ as carrier.
By the way, my phone heats up A LOT while I'm using the browser or Facebook App internet without WiFi, just using the 3G network. But I've also noticed that Facebok app had almost 30% of battery usage. Since it's the app I use the most. It didn't use to be that way on GB ROMs. But after the recent Facebook updates I wouldn't be able to tell since I've been using ICS CM9 nightlys for over over 3 weeks now.
Every time I install a new nightly I make sure to wipe cache as well as dalvik cache. I do that procedure both before and after installing a new nightly ROM.
The only thing I changed is the launcher. I use APEX Pro 1.1.1 instead so I can backup my settings and desktop apps if something goes wrong and I happen to do a full wipe.
I'm running latest update-cm-9-20120506-NIGHTLY-galaxysmtd-signed.zip with stock, default kernel. No Overclock or any other mods.
Other than that, I think this is the best ICS for my i9000. I experience no FC's and no Low Storage problems. The albums are not quadruplicating my photos like other ROMS and the compass works great on Google Maps. By the way, 3D gaming is just great with v504. Real Racing 2 runs nice and smooth on it.
Thanks for the great work Devs and sorry for making this too lengthy.

I can't really be sure. I haven't checked their battery stats at the time of the drain, so all I'm going on is that they agree with my description.
He'a a bit of a noob so I'm not sure if hes just agreeing for the sake of agreeing.
(I know... a noob with a nexus... )

Following from your comment about Mobile network signal polling. You would expect a toggling of Airplane mode to disrupt the battery drain, right?
I definitely toggled it during the fast drain... maybe toggled too quickly for the network to shut off
Will try it again, if/when the fast drain occurs again.

Heavy battery drain and heat up
Hi, same problem just started yesterday

Does it happen with the data on,off, airplane mode...?
It usually corrects with a reboot

Have you tried the mDNIe Mode settings in:
System Settings > Advanced ?
CM9 >>>>>>>>>>>>>>>> Samsung Stock
***********************************************
Anyway enough of the derailing...
For the people who get this fast drain issue:
1. Is your phone connected to Wifi when the fast drain occurs?
2. Are your Wifi settings set to Always Keep Wifi on during sleep?
Could you try setting Wifi to Never use wifi during Sleep?
System Settings > Wifi > Menu > Advanced Keep Wifi on during sleep = Never
And then report back!
Is it possible that Always using Wifi during sleep, even when you are not connected to a router, can cause the battery drain?
This is only a guess, but I'll run this little experiment too. Maybe we are getting somewhere?...
Thanks.
EDIT: I believe Google have inverted the wording on this. On 2.3 it mentions Wifi Sleep... and now its Keep Wifi ON during sleep.
I am suggesting turning it to "Never (increases data usage)"... [as opposed to Wifi Sleep = Never]
