Is this battery drain normal/reasonable?

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.

Definitely not normal... I get about the same 1% an hour overnight.

I'll give it a shot tonight. Thanks.

Tips and tricks: improve JB idle battery life.

Confirm the following option is unchecked:
Maps/Settings/Location settings/Report from this device.
If it is checked, uncheck it.
Here's the difference in battery life -
About half the battery drain with the option unchecked.

Thanks for the tip

What are you talking about? Did you zoom in to see screen on/awake usage? Both are about 7.5 hours of idle time.

I updated my phone to JB and followed the battery saving measures and the battery is dropping very quickly.
Before it could last up to 3 days in standby, now I'll be surprised if it lasts 8 hours.
I'll give it another day then try a factory reset if it does not improve.
Anybody else seeing this?
I have watchdog on the phone and it shows zero cpu off time.

Just install better battery stats, there is also a way to dump the same info in terminal but I don't use it. You are looking for alarms apps cause. It's most likely maps, followed by talk, exchange client, or anything like Twitter, FB,g+,stocks.... but most likely maps location settings

I have been doing a lot of research and the end result is that JB out of the box will eat your battery and yes disabling the settings under maps does in fact help a lot but there is a lot more you can do to get good life... for starters get the simple stuff out of the way, DELETE FACEBOOK MOBILE APP!!!...and twitter and anything that actively accesses the internet in the background... I know this may sound taxing but it is so worth it if yiu just make a bookmark in your browser and view it periodically than have an always active app... next if you are not in a primarily lte covered area set your phone to cdma only... go into settings and go to data usage and here you can see what is using data in the background I.e. facebook... and go there and check the restrict app box.., disable auto brightness and some have said that if you disable sprint connection manager thing you can do even more.... now that one I cannot be sure about I will post results in the coming days of what I find

You are pretty much correct the FB app sucks but I never really had much problems with it.
A lot of these tips though in general (not directed towards you) are stupid.
Like someone said a while ago I refuse to gimp my phone to sip a little bit more life out of it. What's the use of having a smartphone if you're not going to use it like one.
I always have high brightness unless its dark out. I broke my syncs intervals up to about 4 hours per sync and have push notifications from twitter and weather.
With those apps all I have to do is refresh when I enter the app having those syncing all the time is worthless unless you're constantly checking every 10 seconds.
I say I get fairly decent battery life granted I'm on wifi most the time and 7-8 hours with about 2 hrs screen on playing HD games youtube poweramp and my background processes.

Well in regards to the act of extending the life of your battery these are simply tips that you can utilize in the event you are someone who is out for extreme amounts of time.... I average anywhere from 13 to 17 hrs of battery life with 100% brightness, wifi 3g all of my favorite apps... instagram xda kik kindle Skype etc. And 5 to 6 hrs of screen on time. .. so these gimping tactics more than double my phones live time and doubles my life.... but hey if you can get to a charger after 8hrs by all means but for the most part I cannot until after 13 but i do in fact appreciate your incite

what rom and kernel are u using

Even with changing that setting in Maps I still am not getting the same battery life as I did with ICS. Maps is still coming up as my most used app when I check battery usage even though I rarely use it. Wonder if it may be Google Now causing Maps to keep running.

Oh wow. Sorry from my phone I couldn't zoom in. I see now lol. Thought I saw 90 and 89 or something like that

I had the Maps setting turned off for a few days and also had A LOT of stuff disabled, but unfortunately my battery life (and my wife's as well) wasn't as good as ICS, and quite a bit worse actually.
Sadly, today, it looks like I figured out what the killer is:
Google Now.
This morning, 100% charged, I turned it off. My wife (who still had it on) and I were out and about together for about four hours, we both barely used out phones for that time. When we got home I checked both phones: I was at 96%, she was at 80%.
The only difference that I hadn't already accounted for:
Google Now.
So, unfortunately, it looks to me like one of the two biggest reasons for wanting JB in the first place (Butter being the other of course) turns out to be a big battery hog I don't yet know if there's maybe some setting within it that is a specific problem or if it's the whole thing in general... maybe you just need to disable a card or change an update frequency or something (I didn't touch any so I'm running whatever the defaults are), I don't know yet... but all indications are that's where the problem lies.
That, my friends, sucks.

Well since my phone has calmed down I am getting 13-16 hr easily. Brightness maxed of course and about 4-6 screen on time I will never cripple my phone. Hell I bought it so I can use not to look at. Lol thanks for the post of this though if I'm ever I. A die hard , situation I'll know what to do

Google Now uses the "Report from this device" and "Enable location history" maps location settings to determine your driving patterns so it can suggest alternative routes and report traffic delays. Disabling "Enable location history" will disable the driving pattern suggestions completely.
FWIW Settings | More settings | Mobile networks | Network mode
Changing from "CDMA" to "LTE / CDMA" has gained me better battery life. My wife also noticed the same.

(To save time, I'm cutting & pasting my post from another similar thread.)

"I have had my Galaxy S3 for a week now. Battery life stabilized after the initial syncing, etc. I updated to Jelly Bean v4.1.1 two days ago, and battery life didn't seem noticeably different. However, that was until today. My phone was off of the charger, around 10AM, and had < 5% charge by 4:30PM. I was very busy, so I was hardly using the phone all day. It was in my pocket or on my desk most of the time. One of the only settings I changed last night, was enabling 'Use wireless networks' and enabling 'Location and Google search' under 'Location Services' in 'Settings'. I just disabled both settings, and will see if the battery drain is any less tomorrow. Also, Google Now was off, and was never enabled on my phone. I'll try to post the results, if at all possible..."
So, for me, it seems to be Location Services may have caused my poor battery life, and was definitly not Google Now, as it was never enabled. I'll try using the phone with the settings off, and see if that changes anything...

I do love Jelly Bean; as it is ICS only improved or enhanced. But battery life has definitely taken a hit. I can barely make it through 24 hrs. On ICS I could do a day and a half to two days with really light use. I've tried just about everything mentioned with little change. Good thing I have an extra battery. Thank you Samsung for making a phone with a user replaceable battery.
Thanks for all the ideas/suggestions anyways,

I noticed the huge difference as well. I was walking around Chicago yesterday and not using my phone. After 4 hours I looked and my battery was at 50 %.

Exactly the case with mine. However I have every sensor and sync option checked (if that matters). But it did drop 6% in 6 hours.

Same here...but yesterdays battery life was remarkable...over 7 hours on with over 4 hours of screen on time at full brightness.

I'm thinking Quick Glace setting enabled is the drainer.
Feature is much more sensitive on ATTs.
hmm maybe higher sleep CPU level on ATTs
Sprint GN2 has whats called wakeup lag. When you wake device display has good 2-3 sec delay before turning on.

During 7 hours of sleep I got 7 emails
The one gps hit is no big deal but 3 of 7 marked in shot are much to active.

Same thing for me. Went to bed at midnight with 92%. woke up at 8am with 84%. 1% per hour. Hopefully someone can figure out how to slow this down. Otherwise, battery life seems fantastic

Wifi remains strong no cut outs during gmail sync so we can rule 0ut connection issue.
It appears Google sync is to busy on 3 marks shown in shot so I'm going to disable everything except Gmail & contacts in sync setting.
Hopefully that will be fix

Drained 2% in 9 hours last night with 2 push email accounts (on exchange and one gmail) and gtalk connected. LTE signal at about -90 and WiFi connected.
Seems reasonable to me.

yeah that's how it should be.
As my screen shot shows there is 7 deep sleep wakeup points.
7 emails received , 7 wakeups shown with 3 of them being way to active.
Now the question is why.
Maybe a 3rd party app kicks in gear when email received.
Only thing I have on board is Fancy Widget with auto update disabled during that time frame

I'm getting similiar to this. Tested 2 nights now and in 10 hours I'm dropping 2%. Multiple emails syncing, weather, Google Talk connected. Great usage battery life too.
In the "screen on" screenshot, live wallpaper active, 4 hours of Bluetooth music, brightness 80%, Web browsing and gaming heavy with 40ish minutes of phone calls and 30 minutes of GPS navigation. I hit 6h screen on time and 24h 32min unplugged when the battery finally died. That is stellar.
Also I'm in a LTE area, usually 4 bars signal strength but throughout my day I do leave LTE coverage multiple times. (I travel a lot)

Not sure if this applies to anyone else but last night I removed several Bloat apps before going to bed. I did NOT restart the phone. From doing this caused my phone to not sleep the whole night. Woke up this morning and restarted the phone. Phone went right to sleep after doing this.

Ok second day of sleep testing.
This time my toy is running Modded N7105ZHALJ4 MultiWindow rom with no 3rd party app installed.
Google sync active with 1 email received during sleep period.
Accuweather widget at 3 hour update interval .
Wifi enabled.
I'm still getting the 1% drain but this time only 1 email was received during 7hr sleep period so I can rule that out as being cause.
What the heck is waking up device lol
The AWAKE activity shown in screen shot should not be happening.
Edit
That small period showing Screen On I checked email device was awake maybe 90 seconds.
But from that point as you can see lots of activity happening that shouldnt

Maybe the small awake times are to check email, check weather, update Google now, Facebook, basically anything that is a widget or has check intervals for updates.

nah only thing running in background is Gmail & accuweather.
Gmail remains silent lights up sleep on push , seeing only one email was received that can be ruled out as problem.
Accuweather at 3 hour update interval so we can rule that out as well.
On Sprint version I had all kinds of background apps running during sleep , 15 emails receved and would lose 3-4% in 9 hour sleep session so somethings not playing well on ATT version.
I stopped by ATT store today ran across GN2 owner thats having same sleep issue like many in this thread

What's keeping my device awake? What wakes it up to begin with?
BetterBatteryStats.
Search for it on XDA and you'll find that XDA members get a free version. While it won't give you better battery usage, it will tell you WHY your battery is being used by something else.

Better battery stats is a great program, highly recommended from me too.
Not sure what the sleep problem is. I've maintained the 2ish% drop in 10ish hours of sleep. Great battery life still. Do you have NFC or Sbeam turned on? They have been known to sometimes cause battery drain and not show up as "awake" when looking at battery stats. Try toggling them in settings even if they are off and see if that makes any impact.

Battery concept?

Can someone please help me understand a battery concept I'm having trouble finding out. So right now I have 80% of battery left, and only 40 minutes screen on time. Isn't that really poor? I'm a moderate user, so I just text, go on twitter or instagram and this app.
Here's where I have trouble understanding the battery; other days I would have an hour of screen on time but the only way I get there is to use my phone non stop. Shouldn't the times be the same?? Or is a lot of battery being drained when my screen is off?
Here is more useful information:
I disabled location services in Google now, I have smart stay, air gesture, air view, and multi window on. I'm almost always on wifi. My brightness is around 45% - 50%. My phone doesn't get hot, and I am running version 6/10 of ktoonsez kernel.
I have Greenify installed and I Greenify'd maps, Google search, Samsung watch on and Samsung apps, and other apps that use to run in the background.
I followed a guide to unchecked stuff that said "checking" in Google services framework, in startups, in system tuner.
What am I doing wrong?

That would get you close to 3.5 hrs of screen time on a single charge. Thats not too bad for medium brightness and having wifi on all day. I would say thats about average and you could probably push 4 hours on lower brightness which is about standard for this phone.

Most of those stats are with people who have disabled things like Google Services, Greenify everything, Dont run Wifi or LTE all day, have power saver enabled all day, etc. I would say your pretty good. Its the screen which is the real killer on this device

Keep in mind that screen on time isn't the only measure of the battery use. Voice calls are also a huge battery drainer.
You are thinking about battery life properly by doing it in terms of how much use you are getting and not how long between charges. Screen on time is only half that equation though. Consider it in terms of Screen on time plus voice calls time.
Just for future reference though I know what guide you followed (because I wrote it). So since your questions directly follow the changes made in that guide, a new thread wasn't really needed. Using that thread to keep all your thoughts organized in the same place is best for the entire XDA community so people who read that thread can see your issues and learn from them too.

Phone stays awake a lot?

Anyone else experiencing this? I'm not sure what the reason behind this is but is it normal? After about 7 hours off charge with barely 30 minutes of screen on time, I'm down to 77%. Wakelock shows that it's been in deep sleep for only about three and a half hours. The phone has literally been doing nothing with location turned off, widget updates only once every 24 hours, etc. I'm not sure what's keeping this awake.
I have knock on turned on, but have greenified nearly everything for optimal battery life, including a handful of system apps (left a few one since i didn't know their purpose) but it seems like I should be getting a bit more.
Is anyone else getting this kind of awake time? Hopefully I didn't mess something up somehow. I can post more screenshots if anything.
Also, I am running G3 tweaksbox.

Did you even read the post, or the look at the attachment?
I'm getting my information from Wakelock, and I don't see any applications and/or services that appears to be triggering CPU usage, or screen wake ups.
