First, the set up.
I have an Incredible running Skyraider 2.52 with the 2.6.32.15-adrynalyne kernel. I use SetCPU to set some rather aggressive battery preservation, chief among them being the profile that sets the CPU to 245mHz on screen off (using the Powersave scaling so as to eliminate CPU polling). I have Autokiller set to near absurd levels (the Ultimate preset). I even use Autorun Killer to disable some nonsense apps from starting at boot. Needless to say, battery is a priority.
Also, I should note that I am using the 1750 mah Seido battery.
This morning, I charged my phone to 100% (even a little beyond that, as I charged it with the phone off, but not until I hit the green). I unplugged the phone from my car charger at 9:20 AM. Wifi, Bluetooth, and mobile network were all off. I literally did not touch my phone for the next ten minutes, and yet...
By 9:30 AM, I was at 90%!
I quickly started up Froyo Task Killer, which allows me to force stop programs through Android's own task management. I closed several useless but likeable apps (like ONN and G4) and put my phone back in my pocket.
By 12:47 PM, after not touching the phone again, I was at 80%.
Clearly, you can see the difference in battery usage while otherwise in standby.
Is this a clear case for killing tasks, or is there something else at play? I know that task killers are a cause for serious debate, and 2.2 doesn't play nice with them, but this is a pretty weird case.
You're making an assumption that the battery discharge rate (or rather the displayed rate) is linear. In my experience, this is not the case.
You make an excellent point. However, in most ordinary circumstances, and certainly while running stock Eclair, I usually found that the first 10% battery drain took longer, certainly longer than 10 minutes.
Either way, 1% per hour is, all strange battery magic aside, pretty remarkable for a phone that is in standby with screen off in pocket. Especially when given the lengths I've gone to in attempts to extend said battery life.
once froyo hit i uninstalled my task killer.... haven't looked back since.
I currently run SystemPanel by NextApp.
It will prove to you that task killing is practically a placebo but I highly recommend it just to be aware of whats ACTUALLY killing your battery.
I use the stock battery and the OEM 1500mah. I am pretty happy with what I can get out of the extra capacity battery.
Try turning off 3G when you don't need it using the HTC widget.
If you can't stand the stock apps that always start up on your phone but don't want to delete them do as I did and get the full version of titanium backup (3.99) and freeze all the apps. Out will pretty much just like the name says, freeze the apps. You can then thaw them out when you need them.
I got almost 2 days up time and like 12 of those were up on the 1500 battery. Now I have the 2150 i am at 50 hours up and 10 hours awake with still 50 percent to go, that's first charge too, can't wait till it breaks in
Oh and I was reading somewhere that one of the roms has a problem like that. It might be the skyraider

Autostarts would probably be an easier way of doing this.

why would you bother having a smartphone if your intent is to leave it in the pocket? I get about 24+ hrs uptime one one charge (stock bat). Generally on WiFi, GPS, and Max Brightness for half of it.
Charge at work since I'm at my desk and no problems. Battery life is great, but if you don't want to use the phone in attempts to get max life, seems quite pointless to own such a powerful device.
Skyraider 3.1
You can go into battery info in the settings and see what is causing battery drain.
In my experience, most drain is when I'm inside a building with poor reception and my phone is on overdrive trying to find signal. Usually I turn on airplane mode and use WiFi if that's the case.

Maybe its the kernel. Also I would stop killing the apps, not to save battery but because since they were stopped by the user, the Android system might start them up again almost instantaneously. But this depends on core processes and weather Android is done processing any info or other stuff from that app.

I am not aiming for battery life alone, but I like to leave work and not need to recharge for an hour before I head out. I leave it in my pocket at work because, well, I'm at work. Although I do usually get in a few levels of Angry Birds or Shoot U.
The question is, how can I minimize battery use when my phone is idle so that I have the battery to screw around with it when I want to or have time.

I never knew what that did. I knew the feature existed, but hadn't bothered looking into it. I already bought the full version for totally hands-free installs, so I guess I can now take care of Peep and Flickr.

I had never heard of Autostarts. I seem to find that any apps that aim to disable startup entries always fail to list the apps I am most interested in blocking, but for 90 cents, I am definitely willing to give it a shot.
Edit: I haven't had a chance to determine its effect on battery life, but Autostarts is brilliant. It makes so much more sense to actually change startup entries than to try and stop a task after it starts. I also was unaware of how many events trigger apps to start. That is one powerful app.

The 10% drop at the beginning has nothing to do with apps or task killing. It's a bug, the battery isn't telling the software the correct percentage it is at. Killing apps won't do anything to fix it.
If you want to 'fix' it, do a bump charge. Turn off your phone when it hits green, keep it charging till it hits green again.
Here is a tip on how to increase battery life by at least 50%. For me, it has increased by 83%, given that my S II is relatively new (3 months old). It is an app in the market which you can get for free: JuiceDefender
MUST:
Remove any task killing apps (Advanced Task Killer) otherwise this app is useless as it needs to be on at all times.
I have my settings set to Aggressive, as I don't use my phone much during the day.
My normal on the Bombaridier v3.5 ROM by TricH was 100% at 7:00 AM and 88% at 10:23 AM with only 40 minutes of music and standby with no data connection or Wi-Fi. With JuiceDefender, I get 100% at 7:00 AM and 98% at 10:23 AM with the same circumstances of use. It is worth downloading and will extend battery life. I have 83% more battery life according to my math (which is (10/12)=(x/100)) and it is amazing.
I agree that JuiceDefender is an excellent product for extending battery life.
I have the "Ultimate" version.
JuiceDefender alongside "Battery Monitor Widget Pro" is the killer combination...
I did notice one slight bug with JuiceDefender (JD) - there's a known issue with wifi management. Phone turns itself off occasionally. The fix is to simply set JD "disabled" for WiFi management - problem then goes away.
I also listen to music (Pandora) over a Bluetooth headset (about 3 hours per day).
I regularly get about 18hrs+ (combination, on average: 3 hours on voice, lots of email). Stock, rooted ROM... bloat removed.
I agree Juice defender is purely amazing, according to JD stats, I get 1.83% more battery life, that's with aggressive settings.
Ps: Thanks for the Wifi tip
It'll be hard pressed for any app to extend my 3+ days of usage on a single charge. Just sayin..
I just bought the ultimate. I will let everyone know how it goes after a week of using it.

The first thing that came to mind is; haters gotta hate.
I use it just fine with my purposes.
Check/write emails, make calls. Nifty info widgets for updates. I just don't use it for everything because that's just silly. That's the reason why I get such a long run-time. I already have a dedicated media device, no need to watch videos, etc etc on the phone.
Just because most people don't get more than a day usage, don't mean it doesn't happen.

whoa 18+ with 3hours voice is killer.
i barely get about 16 with 2.5 voice and roughly 2.5 display on time
just fyi to those who don't know. voice weighs heaviest on battery usage, even more so than display.
I can get 2 days with moderate use but I dont realy tLk on the phone and I use wifi most of the time

Use the Darkside X kernel and under clock to 1128000 or something and it still runs smooth.

Best thing you can do to to increase battery life is to disable all those Google services. I don't know why but I make it pretty clear in the settings that I do not want any auto-update or syncing of any sort but it happens anyway, so I have to manually freeze all the **** that Google insists on running 24/7.
Thanks for the tip! Extra battery life is always welcome.
Although jd isn't exactly new, but there seems to be a lot of people who just heard of it now. Not bashing but this just shows that there seems to be a lot of new android users or well xda members since the release of our awesome device. I bet most are all former ifags (don't take me seriously).

Lmao. I think this made my day. xD I was using juice defender way back when the droid eris was new and I still do! It works wonders. When I had a dell streak I went from 6-8 hrs of batt life with no usage to over 2 days.
Sorry if I sound like a tool for asking this but if you turn off the Google gmail and calender sync then how do you get your emails?
U have to manually check for mail all the time?
sorry, having issues with my battery also. I use Juice Defender but the free version - everyone that is having success with it are you using the purchase one, Juice Defender Ultimate?
Ive had my phone since october, and the battery has gotten better and better. And im not doing anything special, stock rom, no juice defender, no task killer, nothing of that sort.
I use wifi tether almost all day at work(about 6 to 8 hours) and I still have 20 to 30 percent left when i head home.
With these larger screens and powerful processors, I can't say I'm totally surprised at the lower battery life compared to all the iPhones. They have smaller screens and the O/S is more tightly controlled and optimized for the hardware to maximize battery life.
With that said, I must admit, I'm somewhat disappointed with the battery life on this S3. I've now had it for two weeks so after lots of tweaking, rooting, apps installs and configs, battery and task monitoring, etc, I've kind of settled into my normal usage pattern which is typically pretty easy on the phone as more than 50% of the time I'm working from my home office with the phone plugged into USB so it is rare I have to leave in the morning and go the whole day without having to eventually sit back down at my computer and plug the phone back in.
However on the weekends, with kids sports and such, I'm now seeing the limitations on battery life on this phone. I have it set to:
Auto Display Brightness
No updating of apps unless on WiFi
GPS and Wifi turned off when I leave the houose (automatically via Llama - I turn them on only when I need them)
Power Saver Mode, all options except CPU power saving checked. (Kind of bought the phone for fast CPU although I'm not a gamer - just a multitasker and web browser)
Auto Screen Tone Turned On
Most other specific apps that have option to not download data except wifi I have that option turned on (aside from Taptu news feeds - 2 hour updates and Alerts from ESPN ScoreCenter - get maybe a couple alerts every few hours)
Haptic feedback turned off
Here's where I was shocked. First time I did some serious browsing was in a movie theater where I got there early and had about 20 min to burn so I did constant web browsing over the LTE connection. Watched batter plummet about 15% in 15 min. Whoa!
So is this just "how it is" with this phone that heavy LTE data usage eats battery like no tomorrow?
Other thing I noticed, is Using GSam, I see a task usually being in the top 3 or 4 most of the time with around 15-20% of the App Battery Usage total. It's called "System (*wakelock*)" and when I look at properties it shows around 6-8 wakelocks and Included Packages is just one "PowerAMP Full Version Unlocker" Included Processes: *wakelock* and com.maxmpx.audioplayer. But this is when I'm not using PowerAMP. In fact it happens after phone has been rebooted and I have never launched PowerAMP once!
I did notice something similar on the HTC One X+ I tried then exchanged for the S3 where I found a task associated with beats audio was eating up CPU/Battery when no music app was open as if it was periodically scanning my large MP3 library of 2,600 songs. Maybe PowerAmp is doing something similar?
I've found I'm not the only one noticing this:
http://forum.powerampapp.com/index.php?/topic/2662-battery-drain/
Well, first off, i think the main reason why the iPhone gets better battery life isn't because of the smaller screen or iOS being "optimized for the hardware". It's probably more due to the fact that it doesn't really run much of anything in the background. Very few apps actually continue to run when you leave them. It's kind of a pseudo-multitasking environment.
As for the S3's battery life.... it could be PowerAmp causing it. I also don't see why you'd want to keep power saving on the CPU off. It doesn't really seem to have that much of an impact on performance that i've seen while generally using the phone for web browsing and such. And no matter what phone you're on, LTE will kill the battery in no time flat.
I think you should give some time to settle your battery first...even after flashing a new rom its take couple of days for the battery to settle down. The first day i used my phone, the battery doed in 4 hours...now after 4 months it lasts for 15-16 hrs of normal to heavy use.
LTE does eat lots of battery, whenever i go in LTE area i have to switch my data off to keep my phone alive. That's why people like to have the ability to switch between LTE and HSPA+. Search to find that mod.
You can never compare iPhone with S3. As the above poster said, there is no multitasking in iPhones. The screen is small and not as good as S3. SAMLOED screen takes lots of battery.

I totally agree with you. You have to give it time to settle in. You can also run a battery calibration to try and help as well. I have LTE here in Omaha and I usually get at least 15 hours before I need to charge my battery. I have a QCell battery and it works awesome.
I will live with the battery life so I can actually see the screen without having to squint my eyes. I used to have an iPhone as well but that was years ago now and Android will always be the best.
Don't get me wrong, as a "Power User" coming from the iOS Jailbreak world, hardware and customization-wise, I love this phone a lot more than I like my iPhone - but mostly it's the big screen that I'm enjoying. Have had a couple crashes in the first two weeks which never happened in iOS but no biggie.
So I suspect its primarily the LTE, but combined with large screen, true multitasking O/S, etc, obviously battery life is a challenge. I would slightly criticize Samsung for maybe being a little too obsessed with keeping the phone thin. I know you can buy the bigger batteries with a replacement cover but that looks like it really adds major thickness to phone. They should have went for a 2500-2700 mah battery and increased the thickness slightly IMHO.
But hey, at least the battery is removable. So I can spend little money and get a QCell, charge it and keep it in my car or on my desk and if I know I'm not going to be able to charge the phone all day, just pop the extra battery in my jacket pocket.
The LTE usage is a bit of a mystery to me. You would figure, with LTE, you can download files faster so you spend less time actually using the phone. But obviously it appears the energy consumption is trumping the increased efficiency in data transfer! Too bad.
Why the battery 'breaks in' over time is even more of a mystery. This latest battery technology should not have any sort of break-in or memory issues. But I'm no battery expert. But my gut says there's something else at play. I've seen many threads over past couple of years that discuss an issue relating to Android doing some sort of "media scan" after boot and/or periodically. Maybe the battery break-in is more about the databases the O/S is creating and updating in the background "settling down" more than anything to do with the characteristics of the physical battery changing?
One thing is for certain though, battery life IS a common issue for most higher-end Android smartphone users. Not a deal breaker in the least for me, but will be interesting to see how the phone "seasons" over time regarding battery. I used Titanium Backup to freeze Power Amp and downloaded N7 instead just to rule Power Amp out. I just took a 1.5 hour shopping trip. Didn't use LTE data. But spent about 45 minutes at the grocery store using their wifi to access all my coupons and shopping lists. Battery was 97% when I left house, 77% when I got home. Ouch. Well, that was probably more like a 2 hour round trip. Still 20% in 2 hours is not good especially considering I had 0 talk time and wasn't using LTE data.
The crazy thing is, Gsam says 12% screen, 86% apps. Under apps it says 23.6% Kernel, 19.3% Media, 19.3% N7 Player!!! And I didn't play any music!!!! This is leading me more and more to believe this all has something to do with having an extremely large music collection (2600 songs) on the phone and the phone is building a database and it just takes time. Pure guess.
Get his app disable autostart of the applications that are not needed. Also, get betterbatterystats to get a more detailed idea of whats going on with your phone.
how bad is your battery life? fwiw my wife's iPhone 5 gets horrendous battery life. makes the s3 look like a miser.
16 - 20 hours would be reasonable IMHO, or a average drain of 4-5% per hour. assuming you're actually using the thing... I never understood people who cripple the thing and never touch it in order to get max life.

You know when someone pushes away an iPhone groupy I'm pretty sympathetic but this post is just a noob rage idiotic post. I didn't even read through all your points but will just say you need to spend more time learning
-there is autobrightness on root (and non rooted) and in fact autobrightness doesn't necessarily save battery...as much utiltiy as having say a brightness notification in the app bar or something like lux that allows you to control brigntness by environment/app etc
-it says nothing of what you have running in the background, spam apps, wakelocks etc (bbs) The fact your apps and music is taking up more battery than say cell tower stanbdy and screen display is an obvious red flag
- says nothing of how you checked your connections and how reception is in your area
Another point is the iphone 4 and 5 are MUCH thicker than the galaxy s3...they hold relative to the backgroudn processes etc running, a much larger and thicker battery. The same physical thickness of the s3 battery you could buy a battery with nearly twice as much juice.
We dont' know how you optimized your phone for your uses or whether you cleaned up processes, apps etc, how cleanly you flashed. Go and learn then come back and cry

Well here's an update. As I mentioned, I froze PowerAmp and installed N7 instead. I could have swore I reset the GSAM battery monitor, AFTER N7 scanned all my media files. Yet once again, like PowerAmp (via System *wakelock*) N7 was third highest battery eater over 2 hours of "normal" usage WITHOUT LTE Data Use, only Wifi and NO TALK TIME and WITHOUT USING N7!
So I dumped N7 and installed Player Pro. Just went out again for 2 hours to my son's basketball practice. Spent the 1.5 hour practice reading e-mail and doing some web surfing ALL ON LTE! Battery went down like no more than 10% !! At the beginning of the practice I played a song in Player Pro for a few seconds then backed out of the app. Checked GSAM 2 hours later, no significant PlayerPro battery usage!
It is more and more looking like something is going on with PowerAmp and N7 regarding cataloging of large music collections. So I'll stick with Player Pro and see how things go over the next few days.
Thanks to those with the constructive criticism. This has been one of the pluses of moving to Android. There's a lot larger population of "Power Users" than on iPhone that are willing to help someone relatively new to the platform.
yea... that's the one thing i had a feeling it might have been doing, but wasn't exactly sure as i've never really been that media-crazy with my phones. Good to see that you found the issue, though.

Yeah, "battery break-in" is a bit of a misnomer. What's actually happening is that the stats the OS keeps on the battery capacity and usage are being rebuilt. It takes a few charge cycles for your system to "learn" what it needs to accurately show you remaining capacity, etc.

Good move! I use PlayerPro and I love it. It's one of my few "must haves", not least of which is its ability to sync ratings back to iTunes with iSyncr. None of the other major players have this. This is important for me as I'm also an iOS refugee and I still have all my music in iTunes.

Thanks to those with the constructive criticism. This has been one of the pluses of moving to Android. There's a lot larger population of "Power Users" than on iPhone that are willing to help someone relatively new to the platform.

power user here too coming from iphone 3g, 3gs, 4 to samsung skyrocket, note, nexus to the current at&t sgs3. all have been jailbroken and rooted for "customization" purposes and the first thing i noticed going to the android phones was how poor the battery life was when compared to any iOS device; even when the devices were stock. I can deal with it because of how much customization i can do with android that i can't do on iOS so for that reason alone i stick with android. and also nothing apple has done has impressed me with their iPhone series yet. might pick up an iPad mini retina one day :laugh:
anyways, back to your battery issue. have you tried going to stock rom or formatting just to make sure its not a hardware issue? i know for mine, one time my data partition that had my music had some corrupt file that had the media scanner always running and killing my battery. i had tried everything and there was no way that in 8 hrs i'd have < 30% left with no usage. i finally deleted and formatted everything, went to pure stock with no files except for my contacts and no email sync. then i got 15 to 20 hours... that's usual for the sgs3, a tad less than my old iphone 4. that told me my battery wasn't bad.
i ended up keeping an eye on wakelocks and re-installing all my apps and putting all my music back on and my battery issue dissapeared and i'm happy. still have poweramp installed, but moved to using google music for cloud and local music. what made me really happy was going to a hyperion battery and the slimmer extended sedio case for 2 to 3 days of battery life on this sucker for a decent price. :good: still have the stock batter for backup too!
I'm not on a Custom ROM. Just rooted.
I installed Better Battery Stats to see how it worked. Don't like it as much as GSAM. Seems you can get a bit lower-level process info upfront, but the graphing is barely readable and it doesn't show percent usage of battery for each process. Just number of s(econds) and blue and red line? Maybe I'm missing a setting? I think BBS may be popular as maybe it existed before GSAM (formerly Badass Battery Monitor I think) or maybe there is just something about BBS that I haven't realized yet is a major advantage over GSAM? They both do the job. Sorry for going off on a tangent.
The process hogging the battery the most now is Google Maps and I know from searching and reading this is VERY common. It can be related to ANY app wanting to poll your location. I'm not yet sure though if the usage is excessive. Looks like not. I turned off all of the Location settings in Maps (but left "Location and Google search" in main Location Setting ON as I read that really defeats a lot of functionality. Google Now wasn't happy I turned of Location History (in Maps) but I still get the current commute times and local weather on my Google Now so I have yet to discover any big disadvantage of turning off most (not all) of the Location settings in Maps if you don't want to share your location or see your location history.
Apparently Google Now and potentially other apps like Facebook, etc. want to use Google Maps to poll where you are. One user said turning off History helped on the battery - makes sense as now Google Now isn't constantly trying to see where you are even if the phone is just sitting on your nightstand! I hate that big brother feeling so anytime an app has an option to turn location awareness off, I usually use it. When I go to use Maps I just turn the GPS on. But I still need to learn what I'm missing out on, when turning off some of these settings. Now I'd like to figure out how to get GPS to turn on automatically any time Maps is manually launched and then turned off automatically anytime maps is closed! That would be nice. Surprised that function isn't built-in to Android as opposed to just prompting you to take you to settings. Guess I may have to break down and learn how to code in Tasker instead of using Llama for my automation needs.
I've left the phone unplugged for what, 8 hours now. Very light usage today. I'm at 80%. BBS is showing 3.5%/hour. That's 28 hours. But like I said, no talk time on the phone today, a half dozen texts, no web browsing and maybe 30 min of total app usage so I would expect 3.5%/hour.
Bottom line is it looks like I don't have any major issues like I had on the stupid HTC One X+ that was getting hot. Seems like the media player switch is what did the trick. I'm just curious why apps as popular as N7 and PowerAmp would be any different. It could have been just timing in that I switch to Pro Player about the time the O/S was done doing it cataloging of the media or whatever it does. I'm sure 2,600 high bitrate songs (14GB) of songs on the sdcard is pretty above average for your typical Android User. Wish there was more in-depth technical documentation on some of these processes though published by Google for us Power Users to read if so desired. Guess that's why we have XDA Forum.

Duh, just saw the first condition in Llama is "Active Application" the problem is, I only want the GPS to turn on when I manually launch the app myself. I hope an app trying to use Maps in the background doesn't trigger the GPS on. Guess I'll find out.
-- add --
I forgot why this isn't possible. Google doesn't want to allow ANY apps to turn GPS on/off automatically due to privacy issues. Is there a setting to let the user decide this? Make me feel like they're treating me like an idiot!
Anyone looking for a boost in battery life download the pimp my rom app and install the battery tweak honestly has made a big difference
Does it seem to slow the Phone down at all?
A little not really noticeable with eco mode off
This has been what I have been using. Works great imo. Not 100% sure what it does, maybe its placebo. Either way...
Haha.

Haha no way it's really working lol tank God I'm a very heavy user wifi all day and I'm at 55 percent unplugged at 9am
After speaking with -------(special person that i know) the issues are far worst than you know. The device was designed to get days of battery but tons and tons of issues prevent it. Most you wont notice. Some are obvious. Essentially it comes down to stuff requiring more power than needed. More cpu time equals more power used. Higher radio use equals more power and etc.
So to fix it we must reduce the backend use. More efficient code equals less cpu time for the same amount of user interaction. Reduced radio issues like dropping connections cause more power needed to get signal back and on network. Think of that like highway vs city driving.
Most people here know wakelock issues cause poor battery. The wakelocks are data based and keep the cpus awake long after data use has stopped. Gps does the same thing. Refreshing graphics and buffer issues also cause increased power consumption.
So what can you do to increase battery life?
Reduce background data use to limit wakelock and other bugs from showing up. This can be everything from increasing sync times to removing apps that use data you dont need. Limit sensors you dont need like orientation and face recognition. Turn off data if not needed, or use an app that turns off data when the screen is off/turns it on a limited number of times per hour(s). Use a watch for time. Screen kills battery too. If you have no service, go into airplane mode. Wifi i think can work while in airplane mode for data. Back out of apps youre done with, some apps still try to run even after switching. Etc etc etc.
Etc.
Something else to consider if at work. Turn it off altogether. It cant kill the battery if off. It boots fast you know.
Btw my photon lasts 6 days in airplane mode and wifi on. Havent hit lucky number 7 yet.

Wow joker, i read talks about "the code" being a mess on the og but that seems ridiculous... tho not too farfetched, this phone was a steal with a contract... it does boot up fast tho lol...
Now when u say increase sync time, ur suggesting to just let the apps sync so theyll stfu?
Im using greenify, and got sum info from lookout ad network detector and i just greenified anything that uses crap like admob just in case... when im at work tho i do keep my data off i noticed it doesnt hold charge half as well with data on... i would really prefer to keep all syncing hidden and not off... the phones so quick if i want to use an app and it needs to sync first i doubt ill even notice a slower startup speed.
Also wut about our screen? I read it was pretty high end and economic batterywise compared to old phones screens is that just smoke and mirrors?
Well I returned mine thinking something was wrong. I had it charged to 99%. Just clicked it off fast, no wifi nothing running I made sure. you know all I could close. About 7h later it was at 75%. Well I contacted Samsung and they said this ", I have duplicated the issue and I am forwarding the issue to appropriate department and they will look in to the issue and resolve the issue at the earliest."
So I'm going to wait.
I had the same problem, changed launcher and loaded battery doctor from the play store, and now my battery is awesome. I can leave wifi on and only lose a percentage or two tops over night. Worked for me...good luck
Actually I was worried about the battery when I first saw reports, but Im pretty impressed overall.
I lose almost nothing while its not being used.
I've been seeing excellent battery consumption during sleep mode.
I don't use (and have in fact uninstalled) touchwiz and much of the Knox stuff.
I've disabled a lot of services using the excellent Disable Services app in the Play store, and I've also set Greenify to be very aggressive, including using the Xposed module to enable the paid version to sleep system apps.
(As an example of stuff I axed - all of the S-note and S-pen related stuff, all of the Samsung sync functionality, Samsung's silly calendar replacement.)
The Snapdragon 800 has some very good sleep and battery conservation available to it, if you don't let Samsung and Google keep it up all night.
There's a lot of great info in this thread:

This is good news thanks all! I thought for sure I had a lemon haha.

I've had two of these now (first one had an issue) and what I noticed on both is after like the first day of usage when going to sleep both drained battery like mad, but it only did it once. I've had the second one now for a week and the battery hardly loses anything overnight so I've been happy.
Seems like there's a battery "break-in" period or something on these devices.
