Sorry if this is the wrong section, but it seems like the only section specific to the Captivate Glide.
My wife's Glide is stock, very few widgets (google voice, battery, stock clock) and Android OS shows up at 40% when the phone is idle overnight and during the day during use. She has fb set up on socialhub with only contacts synced, 2 gmail accounts, and Touch(used to be pingchat). wifi is enabled and connected for most of the day. bluetooth is on too, but only connected when in the car.
I don't think it's Touch since I have it on my Atrix and Android OS is at 2-3% for me.
Any ideas?

do you have apps that can access your location? (weather apps, maps etc.) If yes, you may wanna go settings > location and security > and then uncheck "Use wireless network" in case you have not done it yet.
I don't think that's it. I have location enabled on my phone and have a weather widget. The wifes phone does not have a weather widget.

She might have some app that is are using way too much cpu, try doing a factory reset and check the usage, mine is currently %17.
Also the facebook app is a notorious battery thief. Battery usage percentage isn't standard for different people, if she's not using much features, the majority of her battery will be used by the OS since there is nothing else to use it.

Wouldn't phone idle be the max usage? For my Atrix phone idle is at 70% or so when I barely use the phone and Android OS is 3%. I can try disabling facebook overnight to see if the Android OS usage goes down.
The battery life for this phone is ok. It hits ~30% or so in the early evening, meaning we need to charge the phone if she goes out that evening. For my Atrix the battery doesn't hit 30% until midnight under light usage conditions (no games).
Is there an app or logcat keyword to filter to break down exactly which thread/process is using up the CPU?
edit: nm, going to read through this first
From looking at the wakelocks with BetterBatteryStats the likely culprit for the battery usage is the facebook chat portion of the fb app. The wife has many contacts in the chat, so it's probably polling quite a bit. For me the wakelock count for fb chat is fairly low. fb chat is a must for the wife so I can't disable it.
Also in the process screen I see several kworkers with high usage...not sure exactly what's causing that.
so for whatever reason the battery drain is now more acceptable even though the Android OS usage is still at ~50%. Could be the fb update, but the good battery performance occurred before the fb update.

my infuse 4g has a battery drain because of fb.....it's always the next thing that is draining the battery (i hope to get screenies). I just force close fb (or set refresh interval to "never") when I am done using it....
I can't say that this is same as yours but it may be a thing to look up.

From the betterbatterystats output, I'm pretty sure the high Android OS usage is software related and specific to the stock ROM. The radio and wifi battery usage are normal.
I have no clue what the kworker processes are doing when the phone is supposed to be idle. Overnight my Atrix is 68% idle, 12% cell standby...android OS is 2%.
Idk you could try when putting it idle turn of Bluetooth and wifi and the data network this could help see

BT is already off. I could turn off both wifi and data network and if it turns out that is what is causing the battery drain (does not seem like it)...then what? Don't use wifi and the data network? It seems like there's little we can do as an average user to fix the high Android OS usage when idle. It does not seem like high kworker process usage can be fixed by TiBu or other simple fixes from a user.
Another update from Samsung, custom ROMs, and other dev fixes on xda seem to be the only options.
You need to find the source to find a rom that will repair this sometimes an launcher can make your battery die faster I know that Facebook and the browser use a ton of ram I have a stock app on my phone called application manager and I can stop apps that are using my ram

The native ICS app has some battery statistics. Go to settings-battery and it gives you some indication of what is being used.
Mine almost exclusively says most is from screen.
You might consider some application killing software through the play store.

I find the most useful feature of the stock android battery stats to be the graph.
Settings>battery>click the graph.
If you're "Screen On" and "Awake" bars are close to being the same...it's good.
If awake is on really frequently with your screen off...it's bad.
Keep in mind that playing music and making phone calls will keep your phone awake with the screen off. That's fine.

Some quick things that could save you some battery:
- dissable 4g when you are not using it if you have a gsm hit 2g networks only..
- Turn bluetooth and GPS on when you need them power them off when you are not using them. there's a nice widget you can add to your homescren to keep those settings in check.
- if you are a chatter. install chat apps that use Push. a nice example:
a) msn, facebook chat: Trillian
My phone lasts for something like 20 hours (on normal use) but I recharge it every night.. (when I go to sleep I plug it in). If you are a heavy user you can consider buying a better battery, or keeping a small solar powered powerbank in your bag..

I unplugged my phone before I went to bed to see how much it would drain overnight. I only slept for 5.5 hours. My phone had lost 16%. Is this normal?
I was connected to wifi, only thing I had syncing was Facebook for every 4 hours.
I forgot to screenshot the cpu times, but it spent a majority of the time in deep sleep and 384.
Also, what do the red bars mean in BBS?

Try disabling WiFi as well? Im guessing you dont need Facebook to sync while you sleep, just refresh it when you wake up. Noticed you clock down to 384mhz while screen off. odd how still took away a lot for only 5 hours.

I dont think clocking down helps that much. it doesnt stop the same processes from running, and it takes longer to run them with the lower processing power, especially when the phone has all night to do it /
According to your screenshots you have posted, that kakao talk app is in wakelock, keeping the phone from actually sleeping. Although the other stats seem to contradict this i would be willing to bet this is your problem. I would either disable it from syncing in the app, freezing the process, or somehow prevent it from running. I would put money on it improving battery life drastically. I cant be sure of this as i dont use betterbatterystats but i would suspect the red bar is the time spent in wakelock, while the cpu is supposedly in deep sleep.
That doesn't look normal. I get less than 1%/hour overnight. Though I don't use Facebook or Facebook app. I do have 2 Gmail accounts on auto sync. Weather widget sync/hour. Field trip and Google+ sync enabled and wifi is always on when I'm at home.

Is this the kind of battery life I should be expecting? Completely stock and running Juice Defender. Thanks!
It looks like you need to apply the "Cell standby" fix. That won't help your actual battery life, but it will help your reporting.
Everyone is going to be different depending on usage and signal strength.
Your battery usage isn't that bad, but when I was running ICS I would be able to get over 3 hours screen time and someimtes 20-24 hours total life.
It really varies based on your data usage. To extend battery life, then turn off unused data connections. Adjust your sync frequency, and limit push notifications. Network data coverage also impacts battery life, so in areas that have bad coverage, your phone is going to be searching for signal more often.
Use CPUspy as well and see if you phone is going to Deep Sleep when it should.
Here's a screen shot of CPUspy. Hope this helps!

Your phone is not going into Deep Sleep as it should which is causing the higher drain you're seeing. Post what is using battery stats. Also, try to reboot. You said you were stock, so it could just be a random program that didn't close and is running in the background.
I would check your sync settings too.

Post a screen shot from betterbattery with Processes and Since Unplugged as your parameters. Wakelocks are not the problem. You have an app constantly running that will prevent DS, so a Wakelock is irrelavent at this point.

Ya no dice on that one. Just charge it up and run it for a few hours and then pull a screenie of Processes and Since Unplugged. I wanna set what it shows for your Android System as that is your main culprit.
Some things right off that I see with this last screen shot. First, I don't think that your JuiceDefender is working properly. Usually there is a Red, Green or Blue dot in the upper right corner of the shield. This is an indicator of your radio state. Second, that Revamped Nexus S live wallpaper will munch your battery. It's cool and I own it too, but it does cause some issues with battery, not neccessarily wakelocks though. Third, that Battery Monitoring widget is eating it up too. Not sure if the icon on the top-left is for that or not, but if it is in the notification area, then it is polling and is not caching causing drainage.
Those are just what I am seeing from this last screen. I am more interested in the Processes/Since Unplugged screen shot. Charge up and go get some lunch/dinner (depending on where you are) and come back later on after and post it up.

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.

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.

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.

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.

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?
Simon. You are absolutely correct..

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...
