Hi Guys,
I run a recruitment firm and as you can imagine I am on the phone constantly.
I charged my battery night before last and i still have 30% left with 24 hours showing on battery. I think thats amazing, I installed launcher pro.
Here is the about phone information:-
Voice calls 28%
Display 28%
Android OS17%
Android system 12%
Cell standby 6%
Phone idle 4%
Dialer 4%
i dont get it when people are saying one or the other process is eating battery life or maybe i just have a superb battery in mine
Please ask any questions
Yours suffers from the same issue as everybody else. Only the more you use the phone the less you notice it.
Not exactly sure if it's that simple but you used 70%. 17% of this is used by a process which shouldn't even be in the list, android-os. Thus 12% of your total battery has been drained for no reason. Meaning your battery should have been at 42% at the end of the day.
Not saying 30% left is bad, it is probably better than most other phones,but it should be 42% left in your situation.

Doing a simple math should tell you that Android OS has used 12% of 70%... thus, means 17% from total battery... so he should be at 47% instead of 30%.

I´m following now for 3 weeks the batt threads and I am closely watching my batt drain but honestly I can´t find any flaw.............
While my wife with her HTC desire plays 2 x a day for 1h car drive angry birds and the desire is dry then she tried the same with my SGS II and drains only 30 %
In the morning I read via an Austrian newsreader the news of 2 newspapers for approx. 45 minutes, check mails etc. and it takes 4-5 % in this time.
During day I check mails, download newest apps from market, update existing ones, do some calls, check mails, update my calender etc.
Let´s say - compared to my HTC HD2 (with extended batt) - I use it more heavy since it became somehow part of my body ...............
Still in the evening I am on 40-45 % left and then starts heavy use (XDA, other forums, blinx funny videos, Youtube, trying new apps etc.) and plug it in around midnight with 10-15 % left ..........................
I am quite happy with this.
I have installed Startup Auditor and disabled AP News and most social hub apps, music hub, maps and some apps that load at startup.
I have Juice defender Pro trained now well to my needs
I use Android Booster to clean up and shut down apps automatically without restricting functionality of email, facebook and so on.
Android Booster also shows me EXACTLY which apps use how much of my batt and after one week of verx close surveillance I cannot find any process that eats up my juice in the background.
I fear a lot of You mistake the power-percentage of Android OS as an absolute value.
If total drain is 10% per - let´s say 5 hours - and Android OS is eating 50% it is the equivalent of 5% total juice for Android OS in 5 hours = 1 % per hour (these are approx. my values) and somehow this dream-machine has to work to get it going and doing what we want it to do .....................
Now I leave my HTC HD 2 as a backup completely unused (just updating emails every hour and calendar sync every 4 hours, weather forecast with radar charts every 6 hours) and this then consumes 20 % of my extended (!!!!!! 2.600 mAh) HTC HD2 batt.

Hibernating (S4) does not require any power (the RAM is written on disk), only when in sleep mode (S3).
You must be new or something. Rooting wouldn't cause battery drain. Its what you do after rooting. Freezing things you don't use helps out a lot. Touchwiz always runs in background.

Agreed... all this battery discussion is getting somewhat tiring. People buy these handheld computers to conduct these battery tests to see if their phones will drain less than 10% if idling for over 24 hours... seriously? Why not just get a nice shiny paperweight?
My phone is getting hammered all day long as I use it as my computer away from the office, and I am away quite often. 2 pull E-mails + 2 push E-mails, tons of text messages with customers/my manufacturing sites, running around my region using GPS/Google Nav, conference calls throughout the day (much of which is over bluetooth), checking realtime inventory via the web, etc. I'm lucky if I have 25% left on my phone at the end of a long day.
BUT, that's the point: All my colleagues that use their Apple devices just as heavily are constantly charging their phones throughout the day. I don't bother to charge during the day and have yet to have it run out on me. After doing all the things anyone should do (ie, freezing unwanted apps, making sure there are no rogue apps running, etc), I am getting far better battery life on my SGSII than I ever did on my SGSI running custom ROMS + Speedmod battery saving kernels.
If you are getting odd drain from idling when you're doing next to nothing, there's a good chance you have something going on in the background just sapping your battery.
Does anyone know if there's a way to disable Android from automatically dimming the brightness of the display once the battery gets 'low' (<15%)? I find this 'feature'
annoying. Tried disabling 'power saving mode' and also 'auto adjust screen power', brightness is on manual as well.
I rooted today and installed titanium to freeze some apps but I cant figure out which apps I can freeze without f-ing up the phone. Can anyone tell me which apps to freeze,or forward me to a topic with this information?

You went down 13% in 4 mins -________-. Go exchange your phone, lmao. Or turn off 3G, Accounts & Sync, turn off brightness, and install JuiceDefender. See if that makes a difference. My phone goes down 1% in about 2 hours...
mine barley lasts until evening when I plug it back in... but thats just how these phones are. 1% in 2 hours is very unlikely unless you just don't use it and have everything disabled.
Rooting your phone alone has no advert consequences on your phone's battery life. What you do on your phone does

So you go 200 hours between charging? I find it hard to believe that you only need to plug it in every 8 days.

indeed what a troll
Just turning off push email/notifications can have a significant effect on battery run time. I doubled my run time by putting some reasonable settings on my sync intervals.
I refresh my exchange account every 15 mins during peak-time ( 1 hour off-peak ), Tweetdeck every 2 hours, all other accounts hourly. With moderate use I have no problem going 24 hours on a single charge.
Also be on the lookout for misbehaving apps. I had a single dormant streaming app sitting in the background using over 10% of my battery. I kill that app manually after every use.

As it's being said before, if you do not use your device you get excellent battery life out of it - might as well have a painted brick on your desk.
Mine lasts a bit more than half a day, but I use mu phone a lot for streaming, texting, browsing, a game sometimes. I think it is about average, I wouldn't sweat it. Still beats my old.nexus one in battery life

My battery last about 24hrs on average. I bought extra batteries and I have run each of them until they hit 1% and then I use and external battery charger, bought of of ebay, came with 2 batteries and a charger for them for 14 bucks, and i do have certian things i do that drain more than others, but for instance i watch a 2 hour movie, and started with a fresh battery, (99%) and when the movie was over I was at 73%, much better than when i first got my phone, but i also still use advance task manager which everyone says is bad for the phone, but i just use it and exempt everything that is used for normal operations, then it only kills the apps i have used and want to kill. now the settings does allow you to do this by each app, but i am just lazy and paid for the app back on my G1 days and it makes killing them in widget form so one click. i just tried to exclude all the things that the phone uses to operate smoothly, and kill the rest of the garbage apps, also you can try a program autostarts, i have it as it suggested it in the app forum sticky, costs a buck, but i used it, not sure how much it helps, but like i said all I have done and how i use all of my battery each and every use now gives me outstanding battery life. No 8 days or anything but still tons better than my G1 and i didn't keep much running like i do on this one. Also turn off auto brightness, and just use the slide if you need to turn it up, dont use live wallpapers and turn it to use 2g only, and then when you need the 3g turn that back on, there is widgets to get for that so its a one click as 3g really drains the battery, so when not in use go to 2g if your not surfing the web or wacthing videos off a site, doing those things will help the life of your battery.

That just means that your while your phone was turned on, 74 percent of the total power was used by your display.
Makes sense because you turned your screen on for about 74% of the time.
Try running fix permissions from clockwork. I recently got a boost in power & battery life from doing eugenes v6 mod and the suggested lag.
Vibe the XDApp
I have been on here a couple of times complaining about my lousy battery. Well, today I decided to see exactly how far I can take this thing before it conks out on me. Here are my results.
The phone up-time was just over 19 hours, with 14% battery left. (I took my results at 14% because I didn't want the phone turning off on me thus losing all data.) About 49% of the battery was used by the screen, which was on for a total of 3 hours and 20 minutes during this 19 hour period. The rest was split up among other activities, but the most notable/concerning area is 43 seconds of voice took up almost 2% of total battery usage.
I could probably pull out another half-hour or so usage before the phone's battery totally dies, so my final number is 4 hours of usage out of a full charge. This is total usage, i.e. the screen was on for 4 hours.
The phone was at lowest brightness all day except for 10-15 minutes where I had it on full 'cause I was using it outside. I am not using any CPU throttling apps, or such. Background is not fully black. I use one widget, rest are icons. I have Advanced Task Killer which I routinely use to kill tasks, but to be completely honest, unless there is a rouge task ATK does not increase battery life by much. Phone was on 3G primarily, although there were times during the day when I was on EDGE because of weak signal.
All in all, the battery on the Vibrant is pathetic for what it has (Super AMOLED, 45 nm, etc.) but I am glad I can at least last a day. Hopefully Samsung has addressed battery issues in Froyo.
Feel free to post your results on how long you can make your battery last below, so we can all get a better idea. Please do not post "my battery lasts XX days" - give details on your usage, like how I mentioned the battery was at 14% after 19 hours up-time, but actual usage was 3 hours and 20 minutes. Often times it seems like many people brag about how "great" their Vibrant's battery is, but really they rarely use the phone all day hence the "great" battery life.
I completely feel your pain. I had the same issues with my vibrant also. I personally do not believe it is the battery any more because after I applied the ryanza one click lag fix my battery life practically tripled. I kept a very close eye on my usage and settings for the first few weeks. I would get about 12 hours out of a full charge and I would barely use the phone. Frustrated me to no end because I would hear people say that 12 hours with a powerful phone like vibrant is expected. To me it was not acceptable.
I never changed any settings or installed any programs after doing the lag fix but it certainly had a drastic effect. Ill get more statistics when I get home, im at work right now.

mine has superb battery life. I am always confident it will get me pass the day and more. obviously, if I game and web a lot, it will drain faster. For my typical day, it's perfect. I went on to over 2 days with this charge. What an awesome battery!

Have to agree with this. I tried it out and got quite a boost. I didn't keep as good of details as the OP on my battery use but prior to juice defender a was struggling to make a day. Now a day is not a problem. My typical usage is probably pretty high, lots of internet, lots of tinkering right now plus working on morphs and things, I do keep my screen all the way down except when outside (rarely use my phone outdoors so not much of that), no widgets, no task killer. When I installed juice defender I used the stock settings with the exception of allowing gmail and chat to sync anytime. Juice defender says I'm getting an average of 1.7x the battery life. I think almost all of that comes from when the phone is asleep.
Edit. Checked on details.
Pulled my phone off the charger at 6 am it was at 100%. Used to to do some reading on my way to work (about 30min on the train) worked on some morphs, checked some emails, downloaded some stuff. I'm at 82% and it's 12:20.
Cell standby 39%
Display 33%
phone idle 23%
Various 5%
I use my phone for quite a bit during the day and pull about 13 hours before it starts blinking at me. I personally have zero problems with that amount of battery life from a device of such caliber. My best friend was complaining about her battery in her Vibrant and like I tell everyone else, it's probably some rogue app somewhere. She didn't believe me so we swapped batteries 3 days ago and I still get the same usage times out of her battery as I did mine and her battery life has improved significantly as well.
I don't know what is is that people are doing to get 4-5 hours but 13+ with average use (text, moderate browsing, syncing all day, screen at full brightness all day) is to be expected with this phone. I will post a screenshot of consistency over the course of this weekend to visualize my point.
Also I do not use a task killer of any kind except the Android built in one and I removed hers as well

You mean if you actually use the phone it will drain a lot faster. Your post is a perfect example of what I mean when I said people post very misleading results. For those ~40 hours that your Vibrant has been up, your display has only been on 1, maybe 2 hours (hence only 8% battery usage). Your result is not accurate at all - you aren't using the phone. Anyone can get great battery by letting it sits for hours on in.

Thanks I will look at Juice Defender, but I am not too sure what it will do to help improve my battery which I am not doing already. (I leave GPS off, WiFi off when im not using, have applied lagfix, etc.)
The Droid X is known to get 7-8 hours; and considering the Vibrant has power-friendly hardware, the Vibrant should be getting the same.

When you say 13+ hours, do you mean total up-time or total usage time? Because, as I mentioned in my post, my total up-time was ~19 hours, but usage was actually ~4.

Thanks for clearing that up! Well, it sounds like you are fairing better than me, but without actual data it is hard to say.
Oh, and an FYI: I just called up T-Mobile and had them send me a new battery. FWIW, I am not being charged anything (not even shipping) and I don't have to send back my current battery. I love the retention department .
Can someone post up what they do/what settings they use for juice defender? I installed it but I really don't see how it could save me any more battery seeing that I keep wifi, gps, and all that off, plus my screen is on the lowest setting at all times
Hi all,
What I found out that works best for me is, no task killer, no juice defender, lowest display setting possible, and turning off 3g. 3g ready drains the battery. Task killers are pretty worthless. Do some research on that topic. Android kills programs all by itself. And task killers run in the background, using up battery. My phone is rooted, so I run autostarts to control what starts at boot. My uptime isn't great, but its adequate enough to last from morning to night. I do agee that the battery life when using the phone itself for voice calls is sub part at best. I do believe froyo will help with a lot of these problems. Just my 2¢.
Sent from my SGH-T959 using XDA App
DON'T use task killer. Vibrant has really good system resource management. With task killers constantly killing core system processes, the phone has to use more power to keep restarting them.
You can read more about it here: http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
And only turn on active sync for apps that you absolutely need to have them syncing all the time.
This should make your phone last for a whole day with decent usage. If you are still getting very short up time, you probably have a bad battery. Call T-Mo and ask for a replacement.
It all depends on usage. The first days when I got my Vibrant, I was downloading apps all day, or browsing websites, so the battery barely lasts for a day. I usually leave my phone plugged in to my laptop when going to sleep, and set the laptop to auto-shutdown in 4 hour, so the phone gets unplugged at about 4:30 am. With that heavy usage, I needed to recharge at about 7 pm.
However, now that I'm not playing with it that much, the battery life improves greatly. Now I usually do 10-20 text messages and about 30 minutes voice call everyday, also some browsing on the xda forum, and maybe reply several emails. The battery is usually at 40 percent at 10 pm. The only thing I can complain about is that with 40% battery left, I don't want to do a complete recharge, but it won't last the second day either.

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.
Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.
I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.
I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours
With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.
1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,
I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.
I had problems with my battery, but since I rooted the phone I think that it is getting worse. I am not sure if it is the rooting, but now I am getting Android OS at 52% and the battery barely makes 5 hours. I am a using the phone, but it should last at least 10 hours. I did root the phone in order to delete batterystats.bin but this did not help at all. I used Battery Calibrator, also deleted the batterystats.bin from the Android Terminal followed the procedures of charging the phone to 100% waited until it says full calibrated the battery or delete the batterystats.bin discharge the battery until the phone dies and charged it to 100% again....but still the same thing. I guess the Android OS is killing it. Any suggestions will be greatly appreciated. Thank to all of you in advance!
52% is high, but that also depends on what other tasks you are doing at the same time.
You should have 5 hours of Screen On time if not more, thats what you need to check, not some hours.
Regards.

5 Hours screen on time? I'd love to get that lol. 3 Hours 50 Minutes is about the best i've got, but then that is while battering the net and the camera.
Get around 1 to 2 days battery life though although I am a light-medium user.
Install the free version of Wachdog , and see if it can identify what apps or processes are eating up your battery.

Look here:

So to make it clear. My battery lasts about 5 hours. I do not think this is screen time. This is the total time of the battery. I have at battery use
Android OS 52%
Display 13%
Android System 10%
Email 9%
Cell Standby 4%
Voice Calls 4%
Phone Idle 3%
Maps 2%
I think before the rooting I had Android at around 12-13% and the highest was the display. I keep the display close to maximum brightness, but it counts only for 13% at the moment and it was around 40% before rooting. Do you think resetting the phone could solve the problem?

I will again, and post the reading. Is there anything particular that I have to watch?
That stat you have given is after how many hours of usage?
Besides, what kernel did you use for rooting?
Install 'Better Battery Stats' and see whats going on in background.
And do turn off Wifi, GPS, 3G, Packet Data, Auto sync, Background Data, any running widgets when you don't need them. And also check if you have push-pull Exchange.

I got CF-Root SGS2_XX_OXA_KG5-v4.1-CWM4.zip I have after rooting Kernel 2.6.35.7-I9100XXKG5-CL420550 [email protected] #2. I think it was absolutly the same before rooting
On the battery usage it says 13H 23M but It was overnight and now I am charging the phone. Overnight the battery went down around 50-55% without usage. Yes I have WiFi and Bluetooth on all the time, and I am using 3G all the time when I am out of the house. Also I have a lot of auto sync and exchange, but because of this I bought this phone. I will get this app and see the results. With Watchdog Lite I get
9.9% CPU in background Android Apps
Turn off wifi. You router is obviously one of the ones that are not compatible with SGS2.

I have Belkin N750 DB, and It was OK before. When I turn off wifi and restart the phone Android OS is still at 52%. Also I have no problem with my Galaxy Tab 10.1 on the same router. But thank you very much for the suggestion.
If you have wifi and bluetooth on constantly also 3g , you are really taxing the battery 5-6 hours is about right.

I am keeping the bluetooth on so it can connect to my car hands free. I will turn off the wifi and I will try to see what I will get.
I had simillar problems. High os usage and short battery life.
Used better battery stats overnight with everything data related turned off and fully charged phone. turned out that my facebook app was keeping the phone awake in standby and killing the battery. Lost 55% in 6 hours. Removed fb app and battery life is mutch better. Went from 8 hours with about 1 and half hours screen time to 14 to 16 hours with 3 to 4 hours of screen time on one charge. Os usage is now between 20 and 35%. Use to be at 50 to 60%.
This is with stock kernel with wifi and 3g allways on with some autosync and push mail allways on.

You just need to tap on Display under battery usage graph in settings.
Also FB doesn't stay awake in background if you Exit it. So think before you remove it, if it's needed to be removed or not.

Since the phone was charged it is 1H 32M 16S. I am at 88% of the battery and 9m 3s on Display time. I do not have the bluetooth on, the gps is off Facebook app is removed. The only think that I gained is instead of Android OS at 52% I have it now at 48%
I rooted with KG5. If I try to root with KG6 do you think this might solve the problem? My stock was KG5 on a phone from Expansys USA Polish model.
My battery life has been pretty good. However, the number one thing consistently using battery is "Android System". Is this normal? Thanks!
Same here. On all my other Android phones Screen is the top user.
U are using ips technology on the screen unlike amold that saamy used which kills the battery in hours in full brightness . As you could see that the iPhone has good batttery life because the 720p ips screen.

I've found that rebooting the phone after taking it off of charge, the battery life is awesome. There seem to be some wakelocks that kill the battery and for some reason, charging has something to do with it.
I don't know if this is why, but I heard the G2 has special screen technology that greatly reduces battery drain.

Those claiming that Android System > Screen for battery use on the G2...I'm coming from a Nexus 4 which is also IPS.

Yeah, somthing about 30% lower battery use or something like that. It's 6 hours since I took mine off the charger, must admit very moderate use, some toying, some photos, some mails and 1 phone call. but still, my phone is at 96% battery. My old S2 would be at 60% at this point.

I tried this and it worked. However, one instance is not proof I guess haha. I will experiment more tomorrow (namely, not rebooting after charging) and let you know what I find. I wonder what specifically about charging may cause wakelocks?
Over 48 hours of use, more than 50% battery left. 3,5 hours screen time. Android system worst offender with 35%, screen 2nd with 25%.

If you look at the programs listed under Android System, try uninstalling the ones that you would never use. This has seemed to help me. But to be honest it was kind of unnessary because the battery life is just crazy badass. In a few weeks or so when the devs have there way this phone is going to be epic.
It is two things, which by the way are great news.
A) LG's screen tech which doesn't refresh pixels when the images are static
and B) IPS
What we can't control is screen power consumption, but guess what? We can control android system consumption through kernels and roms. This means that we can *hopefully* expect EVEN BETTER! battery life since the screen is, for 80% of users, the main culprit for energy drain.
Just a quick note that flashing CleanROM on my ATT LG G2 basically took my battery life from <20% at the end of the workday to just under 80% at the end of the work day with increased use on the CleanROM install. Highly recommended.
Been off the charger since 6:50 this morning. Sitting here at work doing some texting, Words With Friends, and a test call for a co-worker...96% at 12:15pm. My Nexus would have been at 40% by now.
So is Android System different from Android OS?
I normally can squeeze out 15-22 hours since installing Snapdragon Battery Guru. Which has been working great until today.
Here's my situation today:
-100% charge at around 1230am. Light to moderate usage leaves me with
-77% between night before and waking up (only dropped like 2% overnight) at
-830, then i worked from 9 to 1230 so i didnt use my phone too much. But since ive been off work ive been using it more so im not too surprised about my low battery level currently.
But what concerns me is Android OS using half my battery! It says its been active for more than 4 hours and i dont understand where it comes from. Its way more than my screen usage even with a screen time of little over 3 hours.
Anyone know whats up with Android OS? It doesnt tell me what is running when i select it so im lost.
Also ive done many of the suggestions in this thread with positive results. Ive been monitoring my wakelocks and since doing some of the suggestions on here nlpcollector has actually gone down.

Just to benchmark .... I used the phone moderatley ..
I did.. a little over 50 hours of total on time
4.75 hours of on screen time,
2 hours of spotify with bluetooth for the entire time,
2 hours of MapMyRun with GPS running ..
then various text messaging and a couple phone calls
The only modifications i've made to the stop experiance is taking of google's location service for programs, but leaving GPS active .. and changing the screen to auto-brightness, baseline of 50%.
I came from the SGS2 ..... with 1 hour of on screen time and the other spotify and bluetooth .. i'd be around 10-20% after 8-10 hours !!!!!
Mines pretty awesome.

I'm not sure if my battery is defective or not. Right out of the box was around 75% and I drained it until it turned off then charged it to full.
Over the next few days at work it's on wifi and then on 3G/4G before /after work. I pull it from the charger at 7:30am and by 7pm its at 40%. Then on Friday night I unplugged it at 12am with 100% and woke up the next day with 80%. It's dropping like 1% about 10-15minutes. Would a factory reset fix the battery drain? or call for a replacement?
