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
using juice defender but not auto task killer

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.

I installed OMGB-6 when it was released. Then flashed invisiblek #21 kernel and the new market. Since I last charged it, I've talked on it for about an hour, used the web-browser (Skyfire) fairly moderately, sent a few emails (Gmail), and spent a total of about an hour of GPS through the application WAZE. I'm left at 22% battery left after about 22 hours of use.
I've been fairly lazy with regards to changing the screen brightness, so it's been on about 50% brightness. I've left sync and gps on during the whole time.
I've been using Watchdog as a smart task manager. I have SetCPU installed, but I haven't used it at all.

Don't think you get great battery life when you don't use it much.

True, I haven't been using it all that much. But compared to other ROM's I've used, this get much better battery. Everything else I've tried out got me a max of ~12 hours even on idle the whole time.
Definitely try to install the kernel. Can't hurt! Just make sure you always have a nandroid backup available.

Hydra 1.13 overclock kernel, stock ROM, stock battery, auto-brightness. I'm currently at 20% battery after 2.5 days. Light usage over the weekend, but there is an hour and a half of talk time in there and a half hour of reading.
The trick to DI battery life is keeping the data network usage/standby under control. If you're trying to send/receive data with no signal, the phone will burn through its battery in 4 hours and I've used 20% in 15 minutes trying to book a flight on a low signal connection.
Realizing this took me a few months since I live in NYC and as such, go through a lot of signal shadows. Some days my phone would be at 50% battery after 12 hours, other times it'd be dead after 6. I now realize that the short days were caused by sync services trying to run when I was in a shadow. You can diagnose this for yourself by going to the cell standby section of the battery usage. If you're over 10% or so without a signal, you have this problem.
You can handle this manually by holding down the power (on the stock rom) and enabling/disabling mobile network. This is a pain in the ass.
I handle this with some simple Locale rules along with the Mobile Signal and Mobile Data plugins. The first is to shut off the data when there's no signal. The second is to shut off the data at work where I'm usually but not always on a wireless network. The third is to shut down the data during my normal sleep hours and airplane mode if I'm at home.
These easily got me to 36 hours so I grabbed an undervolt kernel, which gets me to 2 days of regular use. Daily I do about 15m of talk, 40m reading news/email on the subway, and another 30 mins browsing/messaging/misc. My monthly data use is ~350MB.
While it is likely true that the OP and others have good battery life under their specific use conditions, battery life in general on smart phones is mediocre to poor at best. I have friends with various different models of smartphone (including iphone) and across the board battery life is not good. The exception is blackberry, but I don't consider those competitive from a tech and feature standpoint. Obviously different people are going to have different opinions and experiences based on the various factors that influence battery longevity.
The solution is to stop worrying about it, get a spare or two or three and pop in a new battery when one dies. This imo is one of the best things about the Dinc and Android phones in general. Just my 2c.
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.

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

seems to be even better on ics... the best i had was ~2% per 8 hours...

That's good. Might be a glitch though if your battery is not calibrated. I had an issue when my N1 was showing over 20% and then shut off. When I turned it back on, it showed 0% and turned itself off. Try to discharge it all the way and see it if will shut off before it hits 0%. I would do it as a precautionary measure just to make sure that your phone doesn't die unexpectedly when you need it most.

But my mobile shuts down when battery at 15 %.

what are you guys using to calibrate for your battery? Mine used to turn off around 20-25% remaining but after I reset the battery stats its been more accurate. I get nowhere near the same amount of battery life that the OP has but I also am in a bad reception area.

Do you really recalibrate or do you use the function out of your recovery, which function is busted meanwhile?!

My battery life seems to have improved slightly as well. I guess the complete redesign Google did, has done some good

2. Buy $15 phone at walmart as suggested by alewis2k12, so you will have spare phone if the note goes dead. :victory:
3. Try other ROM + Kernel, to find the most suitable to your device.
I have everything updating at minimum times and BT.GPS Wifi and data on all the time and don't go through a battery in a waking day. I went through one and a half on a flight from SC to LA Using the phone the whole way for internet access and a movie.
Im thinking the OP needs to switch ROMS or buy a Nokia 6126 which lasts about a week

No..all Samsung batteries.
Screen was biggest user....and brightness was set at 20%.
Governor was 'powersaver'!
Data usage/battery drain is huge at events like that where tower usage is saturated and your taking pictures and sending etc.
I knew that...but this drain was unreal.
Granted, its an exaggerated example of how poor battery life is on this device...but a viable example nonetheless.
The Note's battery life sucks.
The Nexus 7....bigger screen, also rooted with same custom Rom puts it to shame.
Wise up to it Sammy.

1. Not Samsung's fault. You're on a ROM that Samsung cannot be held directly responsible for.
2. Nexus 7 is a Device with a different spec, for valid Comparison use another GT-N7000.
3. Go Stock and Report Again - Use the Original Battery.
If you're building case remember to make sure you're under Samsung's Terms of usage. I hope you all remember about the phone that blew up and user brought it up to the media's attention, and later on it was discovered that it was the user's fault (As he was trying to heat a soaked phone from an Oven).
If you're looking for help or assistance, Then I suggest you take it to the Paranoid Android Thread. I'm sure, there are users besides the General Audience that can help you out or users that may share the same issue that you have faced.
Just my N7000 cents.
Well, tablets have considerably larger batteries than smartphones, so that's not really fair.
Also, It's probably safe to assume you aren't running the same apps on either, so apps could easily be blamed.
Instagram, for example, has been known to be a battery drainer unless killed.
As others posted, I also get all day, in general, using PA - although you didn't post which version.
If you have screen display set that low, and your screen time is still the largest (what % is that, by the way? largest could still be just say, '30%'),
then I'd put your batteries under suspect. Some of the knockoffs have very little charge, regardless of what they advertise.

What is the capacity of the Nexus 7 battery?

nexus 7 doesn't have 3g, turn airplane mode on the note, and battery life will double as well. Also, if you're on paranoid 0.5 and not jb, try AniDroid 0.8 kernel, you'd be surprised how your battery life improves
yeah.
I think you should bring up this issue on the Paranoid Android forums.
They sure can help you regarding this battery life issue, especially the developer, coz he will know the tweaks and changes he made on his ROM.
Rather than you blame on the device, which at the end, sammie won't held any responsible for using a custom ROM.
It has been observed that the MediaScanner is taking most of the battery in ParanoidAndroid Roms. Try stopping that.
Also you can replace the kernel and use Asylum insanity kernel to get better battery life.
