Ok, so there was a lot of discussion in Z's FreeX10 thread regarding whether it improved/worsened battery life, so I am running a little experiment. With the aid of Juiceplotter I ran for a few days on FreeX10b4, and then on the stock(ish) Rooted JIT 2.1.A.0.435 found here.

Beta 4 Over 24 Hours
Beta 4 Zoomed in on a period of use
Stock .435 over 24 Hours
Stock .435 zoomed in on a period of use (not the same day as the first image)
Typical use is just web browsing, not games or videos. It certainly looks a little steeper on the Beta4 graph.
Tomorrow I'll flash to the previous baseband and repeat for beta3 vs. Stock. If anyone knows how to make the pictures smaller I'd be grateful... I know how to do it in HTML but I've never posted anything in PHP before!
26/02/2011 Ok, after much delay I'm now running .49 baseband, flashed using Zhidhu's pre-rooted 2.0.2.A.24 found here. As some in the comments have noted, results seem to vary wildly w.r.t. battery life, which is why I thought I'd run tests on them all using the same handset and the same usage (i.e. mine) which should eliminate most variables.
Mine is the best it's ever been personally... Seems like results are extremely varied.
I get a vary of result for example today it has used 49% of the battery in 4 hours o.0

I totally agree! My x10i may last even 3 days with moderate use of data and wi-fi, barely 1 if use it like it has to...

I think there may be a bit of a battery or power glitch. My phone has stopped charging a couple of times, once at 74%, the other at 92%, and the battery has got quite hot. A swift reboot sorted it.
Generally, I think FreeX10 may be a bit heavier on the battery, but it's really hard to tell because it's so much nicer to use compared to the stock ROM that I think I'm using the phone lots more than I was :-D

I had some woeful battery time with Freex10Beta3, but then yesterday it was fantastic - sure, I wouldn't get 3 days out of it, but I could have pushed 1.5 easily...
Trouble with battery life is that it isn't an exact science (should be), but it seems you can change nothing, and have some drastic improvements. Or hardly touch the phone one day and it's dead in no time.
My X10 since new always drains my battery in one day, it's not a hardware problem, since i got a replacement, and then a battery replacement, i wish we could improve the batttery life a little more
i'm on BETA4
I'm not gonna say my battery life has been amazing lasting for weeks or anything but ive had no problem with it. I mean it lasts more than a day or maybe more than two with relatively light usage. And if I'm constantly on it I can drain it in 8hrs but I never drain it completely. And I've seen consistent life over the roms I've used as long as the flash was good which sometimes takes a couple times. My mom has one and she uses it only sparingly and it lasts over a week so in reality for having a computer in your pocket the life is not that bad. Besides do you really need to update your twitter status every 6 minutes??

Nice Idea.
Personally I found that the battery life on Beta 2 was better than Beat 3 and 4.
Is is possibile to add it to your test?
Also the only only diffrence between Beta 3 and Beta 4 is the Baseband...
That's really what I'm testing... however I haven't had time to flash back to the old baseband yet. Real life tends to interfere...

Using Bitsnacker's 2.1 ROM on .435; no data, BT, GPS and STILL a strange battery leak I can't seem to trace. F.Y.I. also using SetCPU and AutoTaskiller, and a few Sysctl tweaks, so I may have created conflicts in my ignorance....
I've had a couple of times, since using b4 a weird thing where I plug it in and it drains really fast down to zero while charging. Rebooting seems to fix it though.
If it happens on b3 or stock 2.0.2.A.0.24 I'll know it's a fault with the handset and not a software issue.
As far as I concerned, there are plenty kernels for GS2: KE2, KE7, KE8, KF1, KF2, KF3, KF4, KG1.
But after I flashed the [2.3.4] VillainROM 2.0 for SGS2, I tried two different kernel, they are KG1 and KF2. But I found out KF2 works way better, it can last about 8 more hours than KG1. The kernels are from

I did full wipe before I flash the ROM. I use Odin3 v1.85 flash the kernel in the download mode and works perfectly.
SO, the only difference is battery life.
UPDATED:
This morning's screen:
Around 3% drop after 7h.
Not really remarkable, but I guess KF2 is better.
What do you guys suggest?
Please, tell me which kernel you are using, the Rom and the battery life.
Screen shot is WELCOME!
Cheers!
kernel
That sounds unlikely. I didnt test it yet but i will test it. Atm i have KG1.
a question a bit off-topic: Can I flash an stock kernel of a different ROM to my current ROM?
For example:
I'm using the KF3 spanish ROM (2.3.3). Can I flash only the kernel of KG1 (2.3.4) to my ROM?
I have KF2 for a while now, I'm very happy with it.
Did a test a few days back, went to sleep and put the phone in airplane mode, battery was 87%.
When I woke up (8.5 hours later) battery was 85%.
A 2% drop in 8.5 hours, not bad.
While i have no evidence, I too believe this to be true, when i first got the phone I was on KF2, lasted ages, now it struggles for 10 hours. I don't fully understand the android OS so i just do as the ROM devs tell me.
Bit more complicated than just a kernal is battery drain .
Firmware modem apps running all can play a part .
jje
I am using litening ROM 2.1 with KG1 kernel for a few days now and I think battery was better on KF2 so I switching back to KF2. I participate in the poll when I am sure which gives more battery life.
Off-topic: I have lost count about the number of updates that Samsung released in different parts of the world. But sure that there were atleast couple of updates for every region.
Once the GS2 is released in US (if at all it's released there), there will be 1 update in 12 months and there will be countless articles in every blog. Somehow updates just don't roll out in US.
KF3 Kernel KE7 modem Villain 1.4 rom no battery complaints .
Once 2.3.4 becomes a full release i shall try that .

Could you post your screen capture of the battery usage, either of the kernels would be fine. If you can post both of them, I will be really appreciate that.
I will post my screen tomorrow.

I don't think a kernel has too much to do on battery life. But Push email exchanges, Active Sync and some apps. Use ATK, problem solved.
I'm using Lite'ning 2.1, bloatware removed, sync on - I take my phone off charge at 8.30am, it's normally on my desk not being used for around 3 hours and unless I start using it, the batt has never dropped below 100%.
I'd like to leave it longer to see just how long it will stand by for on 100% but I want to use me phone!

I am having trouble with the batter at the moment. I am using villainrom 2.0 with KF2 now, using xda app for about 25min and my 13% is gone. Last night, I am using KG1, I turned the phone into the flight mode, after 9h, the battery drained from 98% to 26%. That was really strange. I have nearly 150 apps installed, most of them are small simple apps like for finance, business, social networking, tools, not much background running apps.
I wish someone can explain to me.

While the Android OS bug still reigns supreme, stock KG1's battery life is unparalled for me, as long as I keep WiFi off. With WiFi on, Android OS is always higher than 50% and the battery life is crap, but it has always been like that on all kernel versions up to now.

Just thought I'd give a quick review of Cyanogen Mod 7 battery life and performance.
Standby battery drain of about 1.5%/hr with 3G, backround data on, auto-sync on, wifi on, GPS on.
I've never obtained such great battery life on any stock rom or stock-modified rom (I've tried a few different ones over the last year or so)
The performance is also much better than any of the stock-based roms (no lags).
No need to create new topic for that information.
fan/zombie boys everywhere
aple has ones so why not android ;]
Which nightly are you using? Which kernel?
After a night my Galaxy S is always dead. I solved the problem disabling 3g connection and sync. Stock rom 2.3.3 and semaphore kernel.

Sorry to say but useless thread. Just keep the damn charger always near you and battery life wont matter.
Btw did cyanogen pay you for posting this?or........
haha I had the same thought
I used to always hear about CM7 having god-awful battery life. I don't know if people were lying or if they fixed some major bugs, but I certainly have no complaints about my phone's battery life (running CM7, of course). I get through way more than a day.

That's my current battery stats. Haven't used the phone too much the last little while, but getting over 24 hours is not uncommon—I actually very rarely see my phone last for under 24 hours, and that's usually because of 5+ hours of screen on time. For that battery, I'd say about 75 texts, 30 minutes of phone calls, and about 30-60 minutes of web browsing. Fairly light use, but nevertheless, the battery life on CM7 is nothing to complain about.
EDIT: Looks like something was causing a wakelock the last ~6-8 hours while I was asleep, causing my phone not to deep sleep. If that hadn't of happened, it would still have quite a bit more battery (when I went to bed it was 44%, so it shouldn't have dropped to 27%—it should have dropped to ~40%). This just proves my point even more: battery life on CM7 is not bad at all.
seriusly?
do you see any battery change in that period compared to one earlier ))
when it was awake on your funny screenshot it was discharging with the same when the phone was not awake acordding to that stats so no impact registered
Thanks to share that information...

This sounds fantastic, Cm7.1 is my next choice, on XXJVT battery life is only 12h
thats using juicedefender to activate the data connection when screen turns on, emails still push to phone straight away with gmail so it is fine for me.
WIFI seems to drain the battery a bit quicker but not enough for me to bother flashing different kernels
I saw someone who did 2 WEEKS without charging. Normal using with black wallpaper on 2g network.
seems to be even better on ics... the best i had was ~2% per 8 hours...

I suspect the Android OS is a combination of a number of apps/processes.
When I first upgraded to ICS I had the same battery drain issue.. I promptly disabled Google Photos and Google+ (don't use it) and now the battery easily lasts me over 24 hours with my normal usage (similar to GB). However the Android OS still reads as the highest usage but now its on par with screen usage.
I think Google photos and Google+ were constantly trying to sync.. hence.. the resultant heavy battery drain.. but I still think Google can somewhat optimise ICS to reduce Android OS usage..

My Android OS usage is around 20~30%.
Doing some search and you will find some said that doing a factory reset will help, but other said it just helps in the beginning and then the problem comes back. So I am reluctant to reset it now. Hope Google fix it soon.

You can disable a few system apps in settings/apps. I don't think deleting is such a good idea. A system reset should bring 'm back I recon..
This issue is the only let down for me. I haven't found any fix yet. I've tried all types of kernal and rom combinations. Gonna have to deal with it until Google fixes it. So many users are affected by this

Also disabling apps removes them from the app drawer.. I love the "disable" feature in ICS.. saves me rooting to remove certain apps!
Anyway.. I think "Google Photos" refers to ALL pictures linked to your Google account, i.e., Google+ and may possibly include Picasa.
alright I will fully wipe and install oics v43 and flash glados 2.6....
so how do i stop browser sync and photos?
I don't think this is strictly an ICS issue. I had similar problem with 2.3 gingerbread roms also.
Its like already been said by a few people ahead of me. Its related to the services we have running and synchronizing in the backgrounds. I've noticed I no longer have the huge drain issues as I did with gingerbread. But then again I have disabled a lot of the background services that were constantly syncing.

I would be very happy with this if it is typical usage!
If I can actually get anywhere near this I will be very Happy.
Not as good as I was hoping, but still reasonable. That's right around what I've been averaging with my Moto X.
Not good at all.
The wake locks are horrible!

I think that is looking decent, with 13% of the battery used being on 'Cell standby' it is clear that reception was not good during the day. On my nexus 5 when cell reception is good Cell standby barely registers on the list. Max of 5% usually. So would we be looking at 6.5 hours screen time if reception is good? Also no indication that battery saving has been used or not (doesn't look like it is, on the screenshots as the notification/nav bar are not orange). Or what screen brightness set.
Who knows. It is all guessing until more reviews are out.

Yes, same with me. On my Nexus 5 with quite good reception the "mobile standby" is less than 5%.
With that in mind, we will have more than this.
And see those wake-locks, horrible.
Probably some apps, services, or accounts need to be properly setup and configured.
More battery life from that.
And for more extreme, we can use darker theme
So, I am OK with this early report, it's a GOOD BASE!

Yeah me too. My N5 was charged fully yesterday morning and it just sat at my house untouched all day, and by the time I went to bed it was at 75%, which is pathetic. That's the last dev preview. On KK, it still would have been at 100%, or at worst 99%. I didn't investigate what was causing it, but that was bone stock without a single app installed. It shouldn't be like that. Hopefully the final version won't have that issue.

I agree but some people take these findings to heart and if the battery doesn't live up to their expectations they have an aneurysm.
