I am fully rooted running the latest Baked Snack beta and Pandora goes dead when the phone screen turns off. I assume it has something to do with the task management built into the Rom that I am using but have no idea how I would go about changing it

If you have an app killer instaled make sure you ignore pandora on it and it will continue to play...hope this helps...

Have no idea about this on Baked Snack. The only thing about task killing I see in in spare parts. I will fiddle around with things though, thanks for the input!
Make sure your data isn't set to turn off when the phone sleeps.

Also, check your Pandora settings (menu button) as I seem to remember a setting in there that may turn it off when the screen is off... (From memory, might be wrong)...
Go to your mobile network settings, and there check "enable always on mobile data"
Also, if you have any apps like juice defender, they can turn of data when the screen is off.
Is there an app or something that actually tells me what is running I. The background? I'm currently using automatic task killer but I feel that it only kills somethings and not all.

try system panel. or taskiller
Why do you want to kill the apps? Android will stop them for you if it needs the memory. Hitting the back button at the bottom of your phone should exit you out of the app you're currently in.
What do you have running in the background that's killing your phone so bad?

Autostarts is a good paid app. Prevents certain apps from ever starting automatically.

Love autostart.. cheap and on cm6 with stock root I hit 1903 on quad. Also I removed alot of stuff. Almost barebones then installed my 28 apps. Still get average 1800s. +1 for autostart.

You can back out to exit but doesn't shut down the app when you are done with it. Stays in the background. Developers need to start putting close or exit on apps to close and shut down the app instead of leaving it in background. There is 3 parts.. background..foreground.. and cached..

The back button closing apps is a large myth for most apps. Some are coded that way but not all. As for the other post about AutoStarts, it is a great app for root users. Just be careful. However, 2.2 is great by itself about managing apps and resources on its own without a 3rd party task killer. I use AutoKiller to tweak Android's own task manager to kill off items sooner. Just because you see an app running does not mean it is using battery or hogging resources. Android is not a Windows device.

Well the reason I'm asking is because, I am rooted with 2.2 But I still get horrible battery consumption. I thought it might have been all the background apps still running or on standby. I used taskkiller myself but i really don't see a difference.

Good info on the back button. I always thought that worked for some applications. I don't see how force closing an application can be good for your phone though anymore than force closing a program is great for your computer. But I'm not totally familar with the OS on our phones.
But my understanding about the OS is that it will shut down apps on it's own in case it needs the memory right? And, to your points just having apps open won't necessarily drain the battery.
OP, how's your reception. It's also my understanding that having poor reception will drain your battery worse too. Are you running GPS, wireless, or services that use those resources?
Not at all, I don't even have Bluetooth on. And using system tools I can see that before killing any background apps the phone is using 63% memory when killing the apps its reduced to 42%

autostarts + system panel + juice defender
Take a little time to learn how they work, one you get them set up you'll be a happy camper.

+1 for system panel. This will tell you not only what processes are running, but will also tell you how much battery and CPU they use (and have used over the past X hours). It's invaluable when trying to find the rogue process that's sapping up your battery.

I don't know why there should be any problem with killing an app or service through the app manager. I do it frequently. At first I did encounter unexpected results but these are less now as I become more familiar.
I wondered, though, is there a preferred order of stopping and clearing data/cache through the app manager (in 2.2)?
I didn't know there was background/forground/cache difference: in froyo, it appears to me that app manager shows all of those under "running"--is that correct? Also, you can look at services. If a service (calendar, talk, etc.) is running, for example, it could be an obvious thing to stop if you aren't using it. You will see if you log out of the service first, and then check the service list, that it might remain running.
I think when you re-start the device very little starts with it. You can use that as a baseline.
Playing games online realtime is probably the biggest power hog I've found. I sometimes cannot play for even 15 min.
Other days, the device holds juice for more than 24 hrs.
The signal strength seems to be the main variable in my experience. The phone signal strength makes a difference, so does 3G, and 4G even more. It's like there's a threshhold or a revolving time--sorry, I don't know the right term here--but the device goes round and round searching if it thinks some signal is out there or if you trigger an app that calls for it. OTOH, once the device really finds nothing at all it drops everything. It shuts down entirely and you get really great battery life
Lately the phone started to light itself on every ~2 minutes or sometimes it stops for a while and randomly does it again.
I usually place it next to my TV desk or on my computer one, is that the cause? If so, is it in any way harmful?
re
maybe some app is running in background......
maybe because of some background apps
Like the two people above me said check which apps are running in the background. I don't really know much, but maybe Better Battery Stats app will help. It's in the market. I use it to check which apps keep waking up my device and preventing it to deep sleep, thus draining battery.
Well I press the Home button a few times and even open the Task Manager to see if anything is running and there's nothing. :s
Task manager doesn't show apps running in the background.

Goto
Settings>> Applications>>Running Services
there you will find all the apps running in background
check which application(not stock core applications ) are running end any third party app and see if it helps
Install better battery status and check the partial wakelogs to know which app is conflicting

Thanks everyone. I think there was some left out stuff I forgot to end.
On BBS, My kernel and partial wake locks are mostly under control as far as percents but they have some seriously high wakeup counts. For example, "Key events" has 74740 wake up counts but it's 0.0%. In "other", it's awake time is 96%, as well as no data connection, etc, I have pics so you can see what I'm talking about. According to GSam, the android system is taking the most power and second is the screen. I lowered my max/min cpu and set the phone in power save mode. It goes from 100-30% in 6 hours. I have it on wifi like all the time (poor 3g coverage where I am) and it sits in my pocket. I did the basic requirements ( got rid of apps, fixed refresh intervals, etc) I attached my log.

Of course. I'm on Jellybomb version 11 and im using the stock LJ 7 kernel.
Could I have some help please
I have happy with my battery life but only getting about 12 hours a day. And I read people getting a day and a half? That's ridiculous! I am currently running Jedi XP 8 with Perseus, I kill my apps instantly after use, use full brightness and turn off data when I'm on wifi. So what else? Thanks in advance.

Maybe your full brightness has something to do with that.

Screen brightness es are usually the ones killing the battery.
Full screen brightness is probably the reason why

Coming from someone who LOVES bright screens... unless you're nearly blind, there's absolutely no reason why anyone needs to constantly be running their Note 2's screen at full brightness. Auto-brightness is extremely efficient, and if you don't like how the phones native auto-brightness feature manages things, there's many third party apps which can do it better. Full brightness will kill anything on a battery, from a laptop to a cell phone.

Full brightness can cut your screen on time in half. There is no reason to turn off data when connecting to wifi, it's already off. This is android, constantly killing apps will waste your battery even more.

Why is that killing apps right after use drains your battery? I have come from iPhone so I thought it would just increase it. Also, since apps are running in the background why wouldn't background apps killing your battery? And if I shouldn't kill them right after use, when should I kill them?

Yeah no clue why he said that. Clearing your ram before you turn off screen increases your battery by a lot.

i'm very pleased with battery life on my device. i'm using a deodexed, rooted stock ATT 4.1.2 ROM, with stock kernel, Power Mode off, brightness set to about 40% and screen mode set to Natural. i don't use task killers, battery managing apps, etc. my usage is mainly email, calls, web surfing and listening to music (when i have time).
on an average work day, i can get 16-20 hours per charge with 6-9 hours screen time, about 150 emails (4 exchange accounts all set to push 24/7) and 35-90 minutes in phone calls. at the end of my average day i'll have 15-25% battery left before it's on the charger again. there are days when my usage is above average and battery life will be lower. fortunately, for me, i have wifi available and strong phone signals where i work. the pictures below are an example of an average workday: 15 hours, with 8 hrs screen time, 62 minutes of call time and there's 31% battery left. most of the screen time was related to reading/replying to emails, web browsing and texts.
the OP doesn't mention their expectations beyond getting 12 hrs on a single charge and how he/she uses the device on a daily basis. that will surely factor into their respective experience.

Background apps aren't necessarily doing anything. This isnt windows, Android is unix based, unused ram is wasted ram. The system loads apps into the ram so you can switch back and forth easily.
An app isnt constantly doing stuff in the background unless it is intended (like utorrent or music), or the app is badly made(I'm looking at you weather channel). Your ram is always on, no matter how full it is it will always use the same amount of power, when you're in deep sleep your apps are frozen and not actively running. Killing all your apps just means the next time you use the app it has to be read from internal storage and loaded into the ram instead of already being there in the first place, this actually uses more power. Some apps wont even stay closed and will immediately reopen anyways.
Tl; dr Android has ways of freezing apps when not in use, killing apps just means they have to be loaded again on next use which uses power. Some apps are broken and wake up all the time, use betterbatterystats to help find them.
The only solution is to use something like betterbatterystats and find the crap apps that are breaking deep sleep.

Ive tried using the Auto feature but when I enable it, it dims the screen so I can hardly see it. Ive seen screenshots of other users screens with the 'Auto' enabled and they are much brighter......Am I missing another setting somewhere else?

As I said, there are all sort of third party apps out there, that manage screen brightness and most do it better than the native feature. This is the one I use... although I have the paid version. Best auto-brightness I've ever used on any phone...
