Just curious what everyone's overnight battery drain was using CM7. The lowest mine will go is 10% over about 8-10 hours of non use, only one gmail account syncing, nothing else. This is using every variation of CM7 (stable, nightlies, and weekly's)
Using the new 2.3.5 fruitcake I am get a consistent overnight drain of only 3%.
I have tried everything possible to match that, but I'm beginning to think it's not possible.
i only have facebook but log out when i go to bed yet my phone still drains at least 10 percent every hour haha
I'm loosing also between 8 and 10% of battery overnight. I tried to optimize it in anyway including reducing brightness, deactivate services etc but still the same result. This is something which I hate with CM7 previously I used SGS and I had the same problem there. I don't know if it is a general CM problem or just these two phones.
Strange

That's really weird. Ever since I've started using different versions of CM7 I've averaged 2-3% drain overnight. This was both on the stock kernel and faux's enhanced stock. Only thing I would do before bed is turn airplane mode on.
Lately, it's been 3-4% drain overnight but that's probably because I've been installing a lot of apps (Can't pass up those $0.10 deals). Even after switching to Clemsyn's 1.0GHz kernel I'm getting the same amount of drain. Have you guys tried flashing a new radio or setting up SetCPU profiles?
Attached pic is with a little over 2 hours screen time.

I imagine the op is not refering to stand-by in flight mode. Personally, if the phone is in flight mode sat at my side while I sleep then I might as well switch it off.
My battery drain is probably around 15% over 10 hours on Ba2tF, Faux enhanced stock. That is with 3G on and background data, including syncing gmail/contacts etc. It is certainly higher drain than I would like and was getting on stock Froyo.
However, I think ~2 days standby is not ridiculous - 1% per hour will get you over 4 days which I think sounds reasonable. We all fall foul of spending hours of our time trying to squeeze a bit more life out of our phones but most people reviewing them these days are quite understanding: "the battery life was OK - it got us through a day's use"...
Yes I agree but we have a great large battery and still can't get better life. Is it the CPU draining the battery so much? When I'm on 3G and using the phone actively during the day the battery last for no more than 10 hours. There should be a reason why the CM7 is draining the battery faster and this is what wir are trying to realize. If it was 10-15% more than ok but it is almost 50% more than a Stock ROM

I'd agree except I use my phone as my alarm clock , but point taken. Without airplane mode it would be 5% tops.

It seems that new build of GB gets pretty awesome battery life compared to most older builds or custom roms. I believe Nottach pointed this out when he initially started playing around with it for Darkside. If you haven't tried re-flashing your radio, I would definitely give that a shot. (should be in the OP of the CM7 thread)
I don't think that flashing new Radio will solve the problem. CM7 doesn't come with Radio anyway. Initially I though that the problem is in RIL but after suspending all the data transfer for a night without any change I'm not so convinced that this is the problem. Unfortunately the CM7 mail client is also not perfect and after removing it I'm getting slightly better battery life.
Just for the information.
I loose 3-4% per night (7-8h) in airplane mode.
Weekly 3, Clemsys 1.4 Elite version with a more aggressive memory timings, set at 1GHz and UV with SetCPU .
Good for me.
3-4% in Airplain mode is not an option. We are trying to figure out where is the leakage. I'm pretty sure that it is a common for all CM7 branches.
I lose 1 percent overnight with everything off. No wifi or data is on and nothing syncing in the background. I have never had a phone with such amazing battery life. Not even the old Nokia 3310 or Sony Ericsson K800i compare to this. I am pleasantly surprised.

So here's the situation...basically am getting about 12-14hrs of battery life. I have been switching roms, sticking mostly with bionix. However it doesn't matter what rom I still average about the same.
I'm not sure what I actually should be getting so I thought I would ask. I user my phone for basic use; texting, checking email, 30 min podcast, and an app or something. I don't game or watch videos.
Can we here what people are getting and if there is something that can be done to get more life on my battery?

The other dozen threads on the same topic didn't provide enough information?
Use 2G/3G Network Switcher and stay in 2G mode unless you really need speeds faster than EDGE (downloading a podcast). For texting and email, 2G is fine and will help battery life. Also using Juice Defender can help as well.
Go download Auto Killer, and set it to whatever level you want.
Also, go wipe you battery stats.
See if that helps...
Yup I've done all the above. Just curious if I'm still getting what is standard. I've searched the forums but if you know the best place to look then point me in the right direction. Keep the advice coming

12-14 hours is pretty good. Best I got was with Franken-Twiz 3. I think the J16 modem in Franken-Twiz 4 is killing my battery faster so you can flash Modem J12 or try Bionix 1.8 which has Modem J12 in it.
how do you wipe battery stats?

wipe battery stats
Welp with 3g and wifi off I'm easily getting 16hours and on average I'll have 50-70% left of my battery.
I just normally use it as a phone thou. You know some emails, text messages, some surfing.
Just in case you think I'm nuts heres a screen shot as of now. 98% with 3hours on the battery and 48% with 16hours on the battery.
Last night I went to bed at 10pm and my phone was off the charger since 6am and I had 72% on the battery.
I've learned the more you fiddle with your phone the more battery it uses obviously. I've had several phones so I don't have to constantly play with it. Play videos or stream and well it will eat batteries. Use GPS and wifi it will destroy your battery life. Of course I'm not a power miser, but honestly I use it when I need it and when I don't it just sits there until I do.
Got it thanks

I'm getting similar performance with the JI6 OTA, and I generally leave both GPS and 3G on all the time. I just checked my battery stats and my phone's been off the charger for almost 4 hours and my battery percentage is still at 99%. Granted, I've only made two short calls and checked e-mail a few times but I'd call this very good performance. I also woke at 7:30am and surfed around on my phone reading forums and web sites (my display was on for the ENTIRE hour+) for over an hour this morning and when I plugged back in at 8:45 am, I'd used less than 10% battery. I'm also noticing that my phone is charging WAY faster than stock or JI2.
Personally, I have posted about this topic many times but I'm ignored. My battery was terrible before I rooted and did OCLF. After root+lag fix my battery literally tripled in life. I could go 2 days with the same amount of use. Watch videos, surf internet, make calls, do whatever and it would barely use my battery. After this JI6 update I am back to square one. I 'reconditioned' my battery by running it down to zero then charging it back up completely. It definitely helped but I'm still losing a percent by the minute just having the screen on.
Dont waste your time telling me to use juicedefender, turning off wifi, switching to 2g only, task killers, blah blah blah, or any of that crap. I've done it all. I"m still looking into the JI6 radio draining my battery though. Theres a lot of talk about that being an issue.
The JI6 Modem does drain your battery. No doubt about it. I've switched to JI2 and yes my GPS appeared to have suffered a bit and sometimes my Edge connection isn't as good as JI6, but way better battery life.
Or you can do what I do and leave your headphones plugged in and leave the music playing overnight. Seems to make my battery last about 2-4 hours more than it regularly would. Hope that helps

I have uninstalled any battery app because I noticed they drained my battery faster. What I have noticed about the phone, when I charge it with lets say 25 percent still remaining it charges faster,, naturally,, but the battery drains much much much faster. To remedy this,,i use the phone until the battery icon is blank and blinking before I start charging the phone. Naturally, this causes the phone to need a substantial amount of time to charge however the battery doesn't drain nearly as fast. I am a heavy user btw...give it a shot and confirm what I say.

I flashed bionix 1.8 two days ago, charged it up, wiped the battery stats, and let it dry clean.
The phone was in Auto mode for EDGE/WCDMA, reinstalled/downloaded my apps and some more, tested GPS on a few occasions, watched some HQ content on Youtube, and tested VideoPlayer, a few calls, some SMS and MMS, I listened to my music for the most part on it. 30+ hours later the phone finally drained.
With any stock FW's I could not get through more than 24 hours of a regular use with 2G mode only.
Currently I am at 79% at 11hr mark since unplugged.

True. You have to sacrifice something.
this is the only reason i hate CM7. it drains battery like hell. yes, im already using "conservative" cpu governor and have JuiceDefender installed.
when i was on the stock LG rom, battery life used to be about 3-3.5 days on normal usage. after flashing with CM7 (the latest stable version), i need to charge it every night. if i do a lot of net surfing, battery will last for only 15 hrs.
is there some other gingerbread rom with which i can get back the normal battery life?
ive never tried this rom but ive read that rjtchn's cm7 has good battery life. the last time i checked his rom isnt on xda but u can google his rom

First, you can go back to Froyo by flashing the stock ROM through KDZ. But all your data would be wiped out. Take backups.
And regarding battery backup, I think 25 hours of battery backup on moderate-heavy usage is fine. I'm not sure whether we can get 3 days on froyo with the same usage. I didnt use froyo much as I immediately rooted my phone and flashed CM7 based ROMs.
On Andy's ROM with Andy's kernel, I can get 25 to 30 hours with heavy usage, with 6 hours of sleeping period in between. So it is 20-24 hrs of almost constant heavy usage.
void. #forever
I'm using void. #forever with Franco's v18 BFS kernel.
I had 2 days & 20 hours with moderate calls, SMS & browsing. I think I could have reached 3 days until an exercise app surprisingly kept my phone awake & drained the remaining battery.
Using GB 2.3.3 - at the moment for testing purposes GingerCriccoROM 1.2 and latest Franco GB kernel. 3G data always on, sync on, (fb, twitter, gmail, email etc. autom. check every 30min.) Calls, sms, browsing, pretty heavy use and i got after first full charge and battery stats wipe 1d 14h - still 6% left. OC 480/729 smoothass. Still testing - at the moment i have 30% battery left after 1d and 7h.
i run void #forever and franco kernel
it usually last about 2 days on average (48+hr), i dont use the phone functions that much, mostly just browsing the news and sometimes GPS when i get lost out there, but i keep wifi/background/sync always on since i rely on gmail/gtalk/gvoice heavily
horrible battery life
flashed rjtchn's cm7 just now. And havent even restored backups yet. And as I surf on xda now on my wifi, battery is decreasing by 1% every 2 mins in front of my eyes.... it was 100% at 5.35pm and its 89 at 6.04pm now..... WTH is happening? Also to mention, I had bought my phone only a month ago with incredible battery till I started flashing Roms...
I'm using. Rover theme. Does that have. Anything to do with battery?
I had wiped battery Stat when my phone was in 100%, then I flashed the rom, rebooted, and then connected to USB mass storage for 20 mins to do transfers. ( it got charged again). Anything wrong in this process?

I am wrestling with battery life. Not being able to run 24hrs on one charge seems silly to me.
To use some round numbers, from best to worst given my standard usage patterns: {0}
48 hrs (2% per hr drain) -- stock LG 2.2 ROM rooted, crapware removed, SetCPU onDemand 122-600. Consistently runs 48hrs on a full charge.
24 hrs (4% per hr drain) -- stock ROM as it came out of the box.
18 hrs (5-6% per hr) -- CM7 RC1 unchanged. It seems closer to 5% per hour when I set onDemand in CM perf settings to 122-600 and tore out the launcher (using the delightful Zeam instead)
I can go to sleep with my OptT on the bedstand and wake up 8 hrs later and it's dropped from 100% to 60%.
I did do a brief test of Void forever and like the cleanliness of it. But development appears to be ended so no hope of BT working well or battery optimization. If I had an extra T500/509 I'd send it to the dev so he could continue testing. I did run it for a few hours but after I tested BT I didn't have the heart to go install all my crap on it for extensive testing. {EDIT: going to try it out today and see if I can hit 48hrs with it}
I am a big CM fanboi so I would love to hang in there with Mik until BT and battery are better. I mentioned battery drain in a (pre-CM7RC1) thread once and it was not well received, so I haven't mentioned it again until this thread.
If BT and battery don't eventually get improved (and I assume they will) I'll stick with the stock, rooted ROM.

now the time here is 9:22pm and batt. is 63%. the only thing i did was surfing and mail checking on wifi.

Same here! Just remember to change the governer to sth like on-demand or conservative!
Well... reading you guys talking about 2-3 days of battery life makes me think that I'm either doing something wrong, or my battery is a bit damaged, 'cause the only way I could think my Optimus One would last for 2-3 days would be with no use at all.
I got this phone from a friend who had owned for only 2 months and the phone was already rooted and with a custom ROM already installed (Light 2.2.2 which is fairly close to stock). With that ROM the battery would last for a day max.
Shortly after I started installing other custom ROMs and testing them:
- Devoid Froyo Final: The most responsive ROM I've tried, but I had horrible battery life with it, with only around 18 hours of bat with moderate use and 3G on.
- OpenOptimus: Seems a bit laggy to me, and battery life was not even better than Devoid's
- LOL 1.4.2: I finally settled with this one. The ROM is pretty responsive (although not as snappy as Devoid) and at least with this one I can have a full day of battery life (sometimes a bit more).
I must say that I always keep an eye on apps running in the background and stop those I know I don't need always running. I also use Titanium Backup to "Freeze" apps that I know I won't use on a daily basis (like Google Maps and Navitel GPS).
The other thing I'd like to mention is that I keep GPS off (unless I specifically need it), but I always have data ON, either via Wifi when I'm at home, or 3G when I'm out of home. My Wifi Sleep Setting is set to "Never".
The only two apps that I know are working regularly on my phone are:
K9 Mail: Receiving mails for 5 Gmail accounts (all configured as PUSH so that shouldn't drain much battery)
Whatsapp: Receiving messages from friends and family, but that app is also PUSH so battery drain should be minimal also.
Overnight drain with Wifi On is about 5%
What do you guys think?
BTW... probably during this week I'll flash one of the 2.3.3 based ROMS (GingerLOL). I hope that being a "LOL" Rom it would be as stable as my current one.
Not a long test, but I did put all my apps back onto void #forever for an apples to apples test.
Set it on my nightstand and we both slept for 6 hrs. 100% down to 66% in 6hrs, for a drain rate of 5.7% per hour. Gack.
I suspect the real killer is the broken CM7 bluetooth stack in our devices at the moment, but since I use my phone gets used as a wireless mp3 player most of the time I really need it. When CM7 for OptT gets a fix for BT I think It will be nearly perfect for my needs.

my battery life isnt that good either. but then again more performance=less battery life
Void #forever is truly the best rom I have ever tried.... The best thing on it is that its "void" and u can choose which stock aps to install. Thnx a lot guys for recommending me this rom.
Rjtchn's rom had better performance. Quadrant score was 1005 without overclocking(i don't remember the exact). Void's score is 840. But it has incredible battery.
Its the first rom I have ever seen with cell standby having the max bat. usage on 2g network. (all others had android system). That means just by putting on flight mode, things would go even better

It's a balance issue, I guess.
I was researching another issue and so set my phone (as described below) down for 20hrs 23mins and it is now at 84% battery. 23.3hrs / 16% battery usage = ~0.75% per hour.
Compare that with 5-6% an hour I was getting with CM7 on the bedstand. I suggest that CM7RC1 is , despite it's general wonderfulness, not providing 6x the performance for 6x the battery drain.
I am a CM faboi and have done the "buy Cyanogen a beer" thing on his site. I eagerly await CM7 going gold for our devices, and I hope the battery/performance balance is on parity.
Update and FIX!
My phone is no longer draining massive amount of batt life when idle (3-5% after 7 hours of idle), android system usage is now down to 5-15% instead of 78-97% from before.
My fixes.
1. Turn off data syncing
2. Turn off wifi while on the road (so wifi doesn't constantly look for signals).
3. Clear memory
Yes, att installs a lot of bloatware that constantly update for changes.
If killing those services AND disabling data syncing doesn't help your problem, then you have a kernel problem (like myself).
If this is the case, do the following:
1. Take phone back to att and get a replacement
OR
2. Re-flash your android with the STOCK kernel found here
http://forum.xda-developers.com/showthread.php?t=1286432
OR
3. Reflash with cognition x2 (reported to solve a member's problem, I didn't try this myself).
NOTE** This will root your phone, you will NOT get the exclamation mark during boot up, but kernel counter may be at "1" after this process.
Re-flashing my phone AND applying the three tricks I mentioned above worked for me..finally my phone is no longer crippled with crappy battery life and recharging is A LOT faster now.
I must be going crazy but this sg2 is killing me. I got it from Att yesterday and the battery life has been pretty HORRIBLE. (First time android user btw).
The phone will eat up 10% of my batter life after only 90 mins of idle. I checked the battery usage and Android OS is at around 78%!!! How do I fix this problem? I downloaded OS monitor and didn't really see anything that uses a lot of CPU, except for certain files syncing from time to time (but 2-3% usage usually).
Checked with battery spy and apparently the majority of the time, the phone was hovering around 200mhz 70% of the time and not deep sleep.
It's sad to have only 1.5 hours of display time with a battery of 45% left (7 hours total time)...coming from an Iphone 3gs, this is just unacceptable. I almost flashed to the 2.3.5 firmware but noticed it's NOT compatible with ATT's version of SG2.
I see people who have a total time of 2 days AND a screen time with 3 hours with 30% battery left. I wish I can get half that!
Running on 2.3.4, can't be the infamous drainage bug right? Thought that only happens with the 2.3.3s
Wifi on, application sync on, GPS off, brightness at 25%, using live wallpaper (the windmill). No active apps on. Downloaded aim, epocrates, battery monitor, cpu spy, and os monitor..rest of the apps are stock.
Update
According to my CPU spy
For the past hour that the phone was in idle
2:20mins at 1200mhz
4:52mins at 1000mhz
8:33 at 800mhz
1:28 at 500mhz
10:11 at 200mhz
33:36 in deep sleep
Currently Android CPU usage is @ 97%, display time of 7mins(2%)
2h 30mins since last charge (97% charge)..current power is 79%. Did nothing but idling and checking battery life.
So...that's 30 mins out of the hour in which my idling cellphone was hacking the pentagon....
Also the cellphone is a tiny bit warm to the touch (not cold)
I have 35% battery life remaining and have been unplugged for nearly 11 hours. This is significantly better than what I was getting with a Thunderbolt on Verizon, where I was needing to charge after about six hours of use. 11 hours and 35% remaining isn't the best in the world, but it's only been two days. The phone needs a few days to charge and discharge to determine true battery stats and will probably get better.
Being that this is your first Android battery life will not seem great but let it settle in for a few days it should get better.

Used Nexus S, LG Thrill, Samsung Focus, Infuse, This is the best Android phone for battery. I have 40% left with normal use (emails, calls, music, read news) at the end of the day. Huraaaaa

If you only got the phone yesterday, its way to early to make any judgments on battery life. Battery needs at least 3-5 days to settle in and build consistent battery stats.
Also, what are you settings? Auto Brightness, Bluetooth, GPS, auto syn(exchange emal, gmail, facebook, etc). If your not using these, they should be OFF. It's easy to manually refresh email, etc.
I've seen some people reporting very high Android OS(over 50%) but still getting solid battery life.
I'm at 1hr display time, heavy texting. 72% left, been unplugged for 12hrs
no people what this guy is talking about is the android os bug. i have it too. hopefully an upgrade or different rom will fix it. my phone has been unplugged 11 hours with only 1 1/2 hour display but android os has ran for 52 minutes and now im at 32% battery life. once this bug gets worked out the battery life will be amazing.
I don't think that there is an android OS bug. My android OS shows as being 42% with 13hrs of moderate use and I am still at 67% battery remaining. This is by far the best battery use I have ever experienced on an android device! My cappy would not even come close to this performance and this is on stock ROM and kernel.

I'm very happy with mine, this was the first total drain on a new battery so I know it will only get better.
Total time: 18hr 25min
Display time: 4hr 48min
I think it's the system os, not the hardware. There were a few times when the battery didn't discharge itself at 7%/hour (had it idle for 3 hours and it went down like 2%).
And yes, everything is turned off except the sync app data and wifi. There's no option to turn off 4g btw. It's just weird how sometimes it's in this mode of power drainage, and then sometimes it doesn't drain much..but most of the time, it's draining.
I seriously doubt the phone can only run 2.5 hours worth of heavy usage or 12 hours of standby (it should last days!). If this is "normal" for android, then maybe I should have a visit back to att and exchange for an iphone (and I really don't to!)

I agree - as I said in the Android OS drain thread, even in "good" situations, Android OS displays way high on our systems. I think it's a reporting bug.
I dropped 2% in 5.5 hours completely idle (sitting on my shelf) last night - Android OS was at over 60%. It seems that so far for me, the higher it is, the better my battery life is.
I drop around 15-20% in 9 hours of being mostly idle at my desk at work - it's a weak-signal location so the radio eats much more battery.
One thing is that unlike first-generation GalaxyS devices and interim ones like the Infuse, the GS2 has a coulomb-counter type of battery gauge. This type of gauge sometimes needs to be calibrated with multiple charge/discharge cycles or it will misreport battery state of charge. (However, when calibrated, it's much more accurate.)
Edit: I do have some power management tweaks in the kernel I'm running, but they don't make that much off a difference except in some high-drain corner cases in my experience. I'll be releasing it sometime later this week depending on how well these antibiotics do their job.
Do i need to install a battery app to see the percentage? or we have a way?
Install this app:

If you see "DataTracker-FD" or "Fast Dormancy" as the top wake lock, go into dialer
dial *#*#9900#*#*
disable Fast Dormancy (FD).
By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.

That applies to the I9100.
As far as I can tell, the I777 has FD disabled by default. (This may change once I9100 ROM ports start showing up)
Okay, charged my battery to 97%(I got a beep saying it's fully charged). Idled for the past 2 hours and 22 mins. Battery is at 86%.
According to the battery, my screen account for 2%, and the android system accounts for 97%.
This is a stock phone guys, I have no apps installed!

Just search up "battery indicator" in the Market and you'll get a few to choose from.
I too got mine yesterday and started tinkering around with installing apps and such to test out all functions before I rooted it and move onto cm7 most likely. The 1 things I noticed was that the battery was NOT completely full when it was first turned on at the store so once it got a little lower after playing with it I charged it up overnight. Today the battery was WAY BETTER and was not dead yet. I have been using it NON STOP today, rebooting it, testing it, trying to root it, rebooting some more, some time using tango to test it out, watched a Netflix movie, pretty much taking full advantage of it all day. I finally decided to charge it up and use my Captivate a bit. I didn't keep track of usage and times today but I KNOW it lasted a WAY LONGER time with all I was doing with it than my Cappy. Tomorrow I will check more out possibly before putting on a rom.
So LOOOONNNNGGGG STORY short make sure you charge it up once you get it before messing with it too much and then it will LAST LONGER.

After two nights of completely draining then recharging the battery to full, the battery has gotten significantly better. I'm trying to drain it again before I go to bed tonight but I don't think I'll make it.
I played the entirety of Toy Story 3 on max brightness, and only burned 20% of the battery!
I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?
Thanks!

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.
Note: Wifi is off.
Maybe 3G/H+ keep toggling for sync process?
I do use facebook! haha. and I havent used better battery stats

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
Am envious to those who managed to use their phone for more than a day. I bought this phone for about 2 weeks now and have done the normal full charge for 8 hours on the first time. Since then, I have fully charged twice and let the battery gone flat once. I have flashed Neutrino rom and currently Latveyit rom, and the battery last best 12 hours so far.
I charged the phone to 94% at about 7pm and just made two calls and two text messages. I did a navigation on maps for about 15mins max. By about 11pm, battery is at 57%, I play some games for about 10mins and went to bed, in the morning it's about 35%. I realise that the first 50% really goes fast and after that it's pretty decent until less than 20% and it drains fast again. Background application I have are the normal chat programs, whatsapp, viber, kakaotalk, skype and ebuddy. I have waze running in the background although I think it shuts off after 15mins. I have a mix of wifi and 3g usage, usually on wifi though. Is this normal?
edit: I also have Lookout antivirus running
All your chat programs running in the back ground prevent your device to sleep correctly, they wake it up every time they check if there is a new message.
Try to keep only the apps you use and try for each app to increase the check delay or disable it.
The antivirus does help.
2 weeks is a bit early to make a comment about the battery.
Download Battericalibration from the market and use it every shift rom change.
Read about topic on the forum but not become a maniac in "battery life".
If the screen stays lit for 5-7 hours the battery will be empty in like 7-8 hours. If you only speak 1 hour at it the battery will be empty in 3 days.
All depends on how you use it!
Sorry for bad english.

I thought that the chat programs will only cause problems if there are frequent messages since they're base on push?
2 weeks is early? How does that affect the battery's performance? I thought when it's new, it's most optimum and slowly degrades through time? The screen was off most of the time unless I was doing anything I mentioned or just checking the time which is just on, check then off. I don't think I am paranoid over the battery life, just curious how to get it over a day.

In my opinion the battery reaches her max in 3-4 weeks.
Download the app from the market and use it after every rom change.
I didn't called you paranoic, just that you mustn't be so worried.
My recomandation for a longer battery life is CM7.
GOOD DAY!

You might try 1Ghz faux kernels as well. They seemed to have helped my battery life considerably.
Chek out what apps you have running in the background and be sure you set youre network yourself (my phone was always changing from 2g to 3g and after i selected the network myself it gave me a 1day + boost .
And you shoud know that the litium polimer batteryes are affected by cold temperatures.
I wish you luck!
I did use cm7 (neutrino) and got about the same battery life span as the current rom (laytveyit), and am currently on the faux 1ghz kernel. Anyway, I will see how it performance in the weeks to come and hopefully the newer version of the rom will improve it. I thought cold temperature helps preserve the battery's life span?
EDIT: Thanks for all the advice!

Lol all those chats are you problem imo
The "standard" apps used to figure out what's eating your batteries are:
BetterBatteryStats: for wakelocks
CpuSpy: to tell if you phone is going into deep sleep or not
Built in Battery Usage: to see a pretty graph and tell what's using the most juice
SystemTuner: I just recently started playing with this, lots of information.
Look up BetterBatteryStats here up XDA. There's plenty of threads on how to use it. Look up wakelocks.
