I just have my new Galaxy S2 and first thing I noted is that battery drain overnight in flight mode is significannt. I had a ZTE Blade which stayed in same % even for a whole weekend in flight mode, using CM 7 or the best GB cooked roms.
I tried many ROMs, including stock XWKK5, XILA2 and custom, doing a full wipe install and in every case they typically loose 3-5% in one night or 8-10% in one full day. Only ROM that seems to keep battery most inf flight mode CM 7, loosing some 2% in 24h (but more than ZTE Blade). Next better is The-GingerMod 0.8. I tried killing every running process in installed ROMs but consumption is still high.
In ZTE Blade made no sense turning off the phone at night since startup lost more battery, but with S2 it's better to turn it off if still has battery for another day.
I can understand that phone has some parts always running, and that S2 has a large screen that consumes more power than smaller phones, but I find strange that in flight mode, screen off, everything off there is such a difference with the ZTE Blade.
Any opinion about this?
I tend to put my phone in flight mode overnight (~8 hrs/because I like to sleep when I'm in bed ) and I normally lose 2% (0.25% per hr).
At the end of the day it's easy to overthink/stress/obsess about losing a few % overnight when you've got easy access to a charger most of the time. What I mean by this is you can spend a whole lot of time trying to find/chasing that extra couple of % in battery savings & either not find them or maybe only find 1-2%.
Obviously battery drain will depend on a whole bunch of factors not limited to kernel, rom, how you have your phone setup (apps & so on).
You may be experiencing wakelocks when the phone is in flight mode that might be causing the drain to be a bit higher than it could otherwise be. Get hold of BetterBatteryStats. Install it, read the thread on here devoted to it & you can post your wakelock details to that thread. There's a bunch of guys who post to the thread regularly (including the dev) who might be able to help you nail the wakelocks & maybe squeeze out a few % of savings.
I installed BetterBatteryStats but as for now my knowledge is very limited to decipher the processes, anyhow as I said I tried many ROMs after full wipe being intrigued for this behaviour, so they were clean installs with no app added, but I see that even custom ROMs if they're based on official and no removed apps have many things added in comparison to the more vanilla ROMs the Blade has. This explains why CM 7 (or The-GingerMod) s the one that drains less. Have not tried 'lite' ROMs whith removed apps.
Just wanted to decide if it's better to turn phone off at night or just put it in flight mode.

i am currently using a lite rom based on XILA2 and i have to say it is the best i have used hands down. I never use flight mode at night or anything else. All i do is choose the governor of my choice and that is it. Some governors have a screen off profile. That saves you having to add an extra profile in the cpu apps if you use one. Anyway choose a rom plus a kernel that gives you great battery and stick a governor that has a screen off profile and your phone will sleep like a baby
Now that you've installed BetterBatteryStats, charge your phone fully before you go to sleep, do a reboot & leave it in flight mode overnight as you have been.
If you want to find out if it's possible to squeeze out an extra few % of battery, have a read of the BetterBatteryStats thread on here (search for it), read the first page or so, and the last 10 pages. That will give you an idea of what screenshots you'll need to post/what info you'll need to provide for the guys in that thread to help you out.
As to whether it's better to turn the phone off or put it in flight mode @ night, you should realise there's no right answer to that. It's your phone after all. Battery life isn't the be all & end all as I hinted in my previous post. Obviously if you want/need your phone fully on at night (normal mode), then you're going to lose battery & you'll be happy to lose battery because your phone will be switched on. It's entirely up to you.

I can be a lot of things besides the kernel itself, for instance:
1. Sensors! Turn off motion sensors...
2. The lower cpu freq is too high. Use the lowerst possible value.
3. The cpu governor it switching to the higher cpu freq to quickly. Try interactive.
4. Constant updates of some programs, like Twitter or Facebook. Even if there is no network connection they still run on their scheduled times. I just turn them off.
Hope it helps!

I want to flash to a newer ROM, but then i'll lose my battery-calibration. I will have a couple of days a real bad battery prestation and my battery will also not get better of it. Doens anyone know how to back-up the calibration and how to put the settings back after a flash?

That is not possible since the ROM has to be trained to the battery. It is really very simple. All you have to do is run the battery dead on the new ROM and then let it recharge and it will be calibrated. There really is no calibration data so much as training the ROM to know your batteries empty state versus full state. The fastest way to run it down is turn GPS on as well as WIFI and BT and leave them on. Your battery should be dead in less then half the day.
Also please do not double post. We see your post and if no one answers then no one answers.

i agree on the first part but disagree on the rest
running the battery dead isnt good for Li-Ion batteries, and for running down the battery dead faster would actually put a lot of stress and heat (if youre connected to data and running very heavy apps that uses either wifi or data, or even A LOT of CPU) on the battery as well, heat is a no no for the battery, just let it down by leaving the backlight on and turning off auto standby, works for me and its going good
read some of this on the bottom, might help you

BATTERY SAVING TIPS
The first few days
• Immediately after flashing, you will probably observe very poor battery performance. This is due to the charging circuit having to reset itself.
• The battery meter will not settle down and give accurate readings for a few battery cycles. Give it a few days.
• For the first few battery charging cycles, try to charge to 100% with phone off and then allow battery to drain down quite a bit before recharging. This is so the meter will calculate drain well.
Recommendations
• Make sure you followed all of the flashing instructions to the letter. Especially the part about the hard reset.
• Backlight is set to high. You might want to change that.
• 3G is on by default. Recommendation is to turn it off when you are not surfing the internet.
• Don't drain your batery all the way down until it dies. Not good for these types of batteries.
• The GPS sucks the battery dry. If you want to keep track of yourself, consider something like GPSToday that only wakes up the GPS once in a while.
• Maybe you don't really need aGPS enabled. Disable and check GPS lock times and battery drain.
• Applications that run from the storage card consume more power so install oft-used or background-type applications to main memory.
Troubleshooting
• If your radio does not match your rilphone.dll you can get crazy bad battery drainage. Use the recommended radio or spend some time working out a good combination for your phone/carrier/location/usage.
• Check to see that some application is not still running in the background. Check, do not assume. USe the full Task Manager application.
• Check to see if the screen is still on when you expect it to be off. Soft reset can fix that issue.
• Some radios work better with some carriers and locations. Asking everyone to tell you what radio to use may not give you the best answer. Be specific about your situation.
If you have tried all the above and still can't get over a day with moderate use, you may actually have a bad battery. Try getting a new one that is made by another manufacturer.

I'm not sure that it helps (I do it anyway, lol), but I think it's a good idea to flash with the battery fully charged (and maybe plugged in, if you flash off a card).
But when the ROM is trained, it has to save tha calibration data somewhere in it's system? And when you can find dat data, flash a new rom and put that calibration data back, you do not have to train your phone anymiore, right?
If you flash your rom, You should be sure toloose preety much everything of your settings, as far as I know. And so on you wont be taking anything alng (as long as you havent a good backup-tool with you), ...just adjust the settings another time (If they are too many, tell me what you did, maybe I can help my own sttings ^^ (Hate the battaryusage aswell, ...)
it seems that ever since i rooted my phone til today that my battery life has gone down. alot. i don't really use it heavily but yesterday i drained it to 54%. before in a days use the max it would go down to was 75%.
my batt voltage always is around 4000 mv. i also have the free juice defender app i put on yesterday. i have done the battery recalibration but i'm not sure if i can do it right because of the clockwork recovery booting up when i plug it in when off.
i'm running CM6.1.1 any thoughts? any help will be appreciated.
i have looked at the other batt threads but didn't find anything that fits my problem.
or is all of this normal after a new phone and i'm just being paranoid?
i also have spare parts.
i would recommend this thread, but it sounds like you've done that already.
i would just re-check all of your data/refresh settings...i've never really noticed battery decrease with cm mods...perhaps try CM7?
just installed watchdog lite, will post back with more info.
I'd say it's normal for a new phone. A couple things to consider:
- Low screen brightness
- turn wifi, gps, data off when not using it
- you might consider turning off auto-sync for things such as gmail
I'm sure there's a lot more you can do i just can't think of them right now.
I was getting ridiculous battery drain a while back when I first started the whole rooting and flashing process it was a brand new phone. The thing I did was just reflash whatever rom I was trying to set up. It greatly improved but I don't know if I had messed up with flashing initially then just properly flashed the second time around.

Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.

Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

Hi all,
Only had my galaxy s2 for about two weeks now and still sorta learning about everything. Have tried a few different ROMs and kernels but one problem seems to remain no matter what I change to.
I have done a lot of searching on battery life and was shocked to hear that even with moderate use, people can get way over a whole day of battery life. When i first got my phone (I left it on stock (KI3) ROM for about a week) the battery was gone within about 8 hours. I then tried checkrom v4.0 with three different kernels (speedmod, hellcat, and the one that came with checkrom) and still had mostly the same problem, perhaps got an extra 1-2 hours of battery life? Note that every time I was testing for battery life I had sync, wifi, data turned off and brightness turned down. I also tried running batista70 with the provided kernel, and then later with a stock KI4, which took my battery life up to about 12 hours (a significant improvement but still not as good as i'd like) with moderate use (a 30 min phonecall, maybe an hour of web browsing, and perhaps 20 messages?).
After a bit more research I came across a nifty little app called Cpuspy so put it to use. Leaving the phone with any data/process hungry apps turned completely off, I reset the timers and left it for about an hour. Note that I did this for just about every ROM/kernel combination that I tried. The results were strange. After looking at other people's screencaps for cpuspy, I could see that their "deep sleep mode" state was active for anywhere between 70% and 95% of the time tested. My "deep sleep mode" on the other hand was never more than 50% (at one stage it was at about 20%) and this is after leaving the phone completely idle, no data, no wifi, no gps, no.. well no nothing basically. Every single time i test my deep sleep now, it sits at between about 45%-50%, for some odd reason it seems "capped" at 50%.
Next people would normally say "try betterbatterystats to check the partial wakelocks" and that is the very next thing I did. Setting it to test "since unplugged", turning everything off again, unplugging the phone, and leaving the phone for two hours, the results seemed like they were negative for partial wakelocks. There were only a few processes that were detected in the time and all of them only lasted a matter of seconds. Unless I was using the app incorrectly, it seems that wakelocks aren't my problem. The phone IS entering deep sleep mode, but in cpuspy it seems to be in 500mHz 20% of the time, 200mHz 30% of the time, and deep sleep 50% of the time.
I have just flashed back to stock ROM, except this time i am trying KI4 instead of KI3. Even though i've tried KI4 with batista before (yielding yet again the same results) I thought it would be a good idea to flash to KI4 completely, upgrading the modem and such in the process. Testing it again, it seems to be the same, no more than 50% deep sleep state when left completely idle. The next step will be to chuck a CFroot on and install betterbatterystats again with stock KI4 and check for wakelocks again.
I really would love to do more thorough testing and provide you guys with some less vague information (i.e. screencaps and stuff) but as I dont have a spare phone I am kinda relying on my new gs2 and can't leave it completely idle all the time. Tonight I will do a BBS test along with cpuspy and advise of the results.
Apologies for the long-winded explanation, I just wanted to provide as much information as I could on the issue to prevent having to explain more later.
Any assistance or suggestions would be highly appreciated!
P.s. I've done many forum and google searches on the issue but I can't seem to find anyone with the same problem (most of them are for the phone not entering deep sleep state at all). If I have overlooked an important article/forum post please throw a link my way.
Thanks!
Update: For some reason I decided to try checking the sleep time with my sim removed and I was getting closer to 100% deep sleep! I then proceeded to try a friend's optus sim in my phone(mine is telstra on nextg network I.e. uses WCDMA) And once again the deep sleep time was normal. The only difference between the sim cards is the optus one doesn't use wcdma. Went into the phone's "secret" menu (that's just what my brother calls it ) and switched the network type to WCDMA Only from WCDMA preferred and I -think- it's helping with deep sleep. I am about to do some thorough testing with this setting and I'm hoping for some promising results!
All I can assume is there's something to do with the network constantly "deciding" which network to use I.e. not necessarily the switching itself, but some sort of polling perhaps? Just a guess.. I don't know a lot about mobile networks so I wont pretend I know what I'm talking about.
Anyway, will keep you all posted (that is, to anyone who's reading this). If anyone has any input at all it would be appreciated (even just information about mobile networks and stuff)
Cheers!
I know this question has been asked really lots of times, but I didn't seem to find cases similar to mine.
there doesn't seem to be any wakelock (except 2 which is incredibly short) and it was in deep sleep mode all the time. but yet, it drains almost 5% per hour which i find is really too much...
I've tried lots of firmware (litening, wamanlite, turkbey, stock, ICS) and removed all the unnecessary bloatware to reduce wakelocks to a state as shown in attachment. but still, they do not have any results, still get less than 1 day life without any usage at all...
Could this be hardware problem? I find it gets hot really fast even when i'm just facebooking.
Or is there anything else can i try to do? this device really started to disappoint me ever since the battery life looks like this.
any help will be greatly appreciated.

Try Hydrogen-ICS latest version, it seems to be "the rom" today
Battery life is very good and its overall a stable system.
Make sure to "Fix Permission" after first start, reboot recovery and do it.
Also sometimes "to much junk" in your SD card can cause battery drain, copy your files and format the SD card, you might see some diffrence. (i did)

you got 20Hrs out of your phone? grats! as of lately i've been trying alot of different roms and different customization settings from kernel tweeks to CPU tweeks (undervolting/underclocking) and im even turning off every extra setting that consumes battery power apart from wifi
on best with a 2000Mah battery i get 13 hrs on standby and 4 hrs if im playing a game - these days my phone doesnt charge anymore - it discharges even when plugged in
I recommend downloading HydrogenICS, it's good! Download Battery drain, so you can see how fast your battery is being drained.. Also, let your battery go down to 5% then charge your phone
Something is seriously wrong - you've hardly used it, looking at those graphs.
I'd try a stock anything, and if you get similar drainage send it in for repair/buy a new battery.
this is'nt normal , in sleep mode i can get 20 hours and only lose 9%
use hydrogen and neak , and try , if you get the same result so it will be hardware fault
the 3g data it kills the batt very fast,i don think u got a hardware prblm,cause 20hrs an still to go is good ive seen ppl reporting worse...dude instal better batt stat,3g watch dog but remember batt saver apps too run in bckgrnd so i suggest u stay on a stable rom wiv a custum kernel like siyah or neak an watch the batt in better batt stat.....wen i need more juice i switch to airplane mode in nite then rebot in the morning....i don hav any tweaks or uv,oc but ive seen the batt is very good wen i don use the data or wifi or download or update,pm me if any doubt......cheeeerz
You flashed different ROMs the last days? First thing is you should only flash with full battery and after flashing it needs some time (three full battery cycles e.g.) untill the battery works fine for the ROM.
And you may recallibrate your battery. Turn the mobile off and load the battery to full. Then go to CWM and reset your batterystats. Now unload till the mobile goes of and reload to full with mobile off. If you doe this for e.g. 3 times the battery should be recalibrated.
I must say Omegas ICS + Speedmod or Siyahs Kernel. Best ever. Or checkout Paradoxxxs rom very stable but for me not so good xD

bro, 20 hours is with 99% deep sleep is seriously wrong. better battery stats cant tell me nothing, since i have no wakelocks or whatever, and all those battery savers apps, they spent more battery than they can save. when those screenshot is taken, i can tell you for sure, bluetooth, gps, 3g, wifi, auto sync etc everything was turned off. even brightness is 10% (which is even lower than auto brightness settings). anyway thanks for the reply

You flashed different ROMs the last days? First thing is you should only flash with full battery and after flashing it needs some time (three full battery cycles e.g.) untill the battery works fine for the ROM.
And you may recallibrate your battery. Turn the mobile off and load the battery to full. Then go to CWM and reset your batterystats. Now unload till the mobile goes of and reload to full with mobile off. If you doe this for e.g. 3 times the battery should be recalibrated.

nope, i always try at least 5-6 battery cycles after flashing to see the real graph. and i've read in this forum somewhere, calibrating battery by deleting batterystats is useless for this phone.

I must say Omegas ICS + Speedmod or Siyahs Kernel. Best ever. Or checkout Paradoxxxs rom very stable but for me not so good xD

speedmod is a kernel like siyah rite? i've use siyah before, but it doesn't seem like much help. nonetheless, will try them ^^
thanks for all the replies and recommendation, will try different rom & update again (probably in 4-5 days for trying 2 roms
I have exactly same problem. On GB over night(7 hours), battery consumption was around 9%. On ICS more than 20%, but nobody touch phone. I try few roms: wanamlite, omega, bezke, pure. Now i have hydrogen. Better battery stats shows nothing special. Only thing what i can think is wi-fi. if i turn off seams to be better, not that dramatic, but anyway not that good like on GB.
strange...
let me ask this... what does the yellow color in the phone signal mean? anybody got any clue?
shouldn't it be green/gray ?
in my phone whenever i have green/gray in the battery view the bar hardly goes down on idle but i see a big drain compared to green/gray when it becomes yellow even in idle
let me post a pic to clarify...
i was complaining about sudden batt drop on cm9 ics, i know its 2 diff roms but still the yellow bar got my attention in both pics...
just searched google and came up with red= no signal, yellow=very bad signal to no signal, green = good signal/full
bad signal makes the phone look for the signal in a bad way using a lot of the battery...
guess i found out why my batt suddenly dropped so bad compared to the rest of the bar...
id suggest flashing a couple of modems and testing how good of a signal u get with each and sticking with the one that works for u, if its a weak signal from the provider then find a better provider that covers ur place with better reception...
start from there and then if batt life is still bad search search and search... best of luck with ur phone...
@mazroui
in those 7 hours your phone should lost 9 - 10% of battery, but not more than 20 unused, what is process causing that usage?
for me: i charged phone before sleep, when wake up after 7h i had 20% left.
Android OS - 92% , rest for cell standby, phone idle and screen. Wi-fi was setup to sleep when screen is off. Better batery stats show that wi-fi was on for almost whole time
Cell Standby and Phone Idle using that much of your power means that the signal in your area is horrible and the phone is struggling to maintain a decent connection with the towers, this can drain a tremendous amount of battery depending on how bad the signal really is, the yellow bar means it's not optimal but there is a large degree of variation between the top end and bottom end of the yellow bar spectrum. Try a different modem or move your phone to an area with better reception and see if you still get this sort of drain.
Android OS is misreported by practically every Kernel because for some reason Samsung accidentally made Screen On add to the Android OS bar, so your Android OS usage is actually AOS + Screen On, for the most part high AOS usage can be ignored as a source of drain using the phone info battery screen, I would look elsewhere for the problem. Sometimes rogue apps hide their wake locks in another wake lock, for instance if you have facebook or many of the IM programs on your system, they poll their servers a lot causing a kernel wake lock called 'svnet dormancy' (in gb) or 'multipdp' (in ics) this causes a lock of 5s to ensure proper packet transfer, if your app is requesting packets every 4 seconds, then its essentially a permanent wake lock but may not be reported as the app being the source.

IF yellow means poor signals then strangely iam getting yellow line but the signal bar shows full signals on home screen.
Any comments

There is a defect with Android where good signal strength is mis-reported on this screen as yellow, even if you have 100% signal.
Until you go to About Phone > Status, just once. Then when you go back to this screen, it will start reporting as green if you have good signal.
I've tested this out on my phone, and confirmed it... try it out yourself.
I stopped caring about it, so I just ignore it unless it gets reported as red.

Signal in my area is far from perfection, but in same location, on GB i had 9% consumed over night, but not 70 %. I turn off GPS, BT, leave only wi-fi and data. And over night when nobody touch phone, screen is off.

If you look at the graph in the right pic you can see that the curve is less severe when WiFi is active, while this doesn't prove my point that its a network issue it does increase my suspicion that the issue is mobile data related.

Something is horribly wrong with that. Do a full wipe. If it still does that, reflash your firmware. If it STILL does that, maybe flash to a newer stock ICS firmware? Then as a last resort, you may want to go back to GB.

This guy may be onto something, actually. First thing you should try is flashing a different modem. THEN do all the stuff I said above.
EDIT: just noticed you're in Oz. Try flashing a T modem. Most Australian users report much better results with both battery and signal after doing this.
