This is not a battery thread. I just wanted to do some maths based on some findings of my own.
I post this screens, taken at 50% battery. I rebooted when full battery for a fresh graph. I'm running "stock" 2.3.4 KG1. Data is always on, two push mail accounts, display on Auto, no gaming, no photos for today.
So, if the graph are accurate (I really doubt that):
1. 17 hrs 38 mins total time on for 50%
from this:
-1 hr 48 mins phone calls
- 45 mins Android OS
-1hr 2 mins display on
-Android system (the thing responsible for widgets, push mail and so on, basically for apps) 7 mins 50 secs!
-Phone idle 16 hrs 35 mins. TIME WHEN NOTHING IS SUPPOSED TO BE RUNNING IN CPU FOREGROUND
- Navigon comes up with 11% BUT I NEVER USED IT- and there are no details on CPU usage either.
- I used 20 mins of sync Wifi for the later part of today, wifi doesn't show on the graph- no clue why.
Here I stand pretty puzzled:
1hr 48 mins of calling + 16 hrs 35 mins of idle is 18 hrs 23 mins! assuming that idle does not include when calls connected and screen off .
Here are the figures for the AOS and how life would be without it.
Android OS chewed 14 % of the 50 % battery. Calling ate 43% for 1 hr 48 mins. If it wasn't for AOS bug, I would have had power to call for some 36 more mins to get to the 50% battery. That's like 30% more talk time without the bug.
Display, set on auto, drained 10% of power for 1hr 2 mins. Android OS bug stole almost 30 mins of display time for every hour . This is 50% wasted power.
Phone Idle is 4% for 16 hrs and 35 mins. So, basically, every minute under raging AOS eats 0.31% of battery. for every 1% the phone idles for 4 hours and 9 mins (and ideal stand-by time of four and an half days ). EVERY MINUTE OF ANDROID OS EATS AWAY 1 HOUR AND 22 MINUTES.
Also, the Widgets and all other stuff are actually consuming half the power eaten away by AOS.
So, if by miracle, the faulty driver is resolved by Samsung, we should get :
30% more talk time
50% more display time
350% more idle time.
Or, for the connoisseurs:
Android OS comes in, battery goes flat. No miscommunication. You can't explain that.
Good post, my own experiences (i only have my GS2 a few days coming from a HD2)
I deleted my battery stats last night and left my phone on,data was enabled nothing like bluetooth/GPS,etc,brightness is set to automatic brightness the phone was at 99% and from 12.29am to 09.59am this morning when i checked it was 83%,not too bad i suppose but could be better, i have fast dormancy disabled and i froze the Samsung apps with Titanium Backup,however the Android OS was at 41% and Maps and Cell Standby both 15%, since then ive been using the phone for some Internet, 1 call and sent a few text messages and it's now currently 12.41pm and it's at 47% and the display now shows at 35% and the Android OS is 23%, im running Lite'ning ROM 1.5, does this seem normal or quite excessive im in 2 minds myself, does the Android OS usually be as high as that when in standby,when im using the phone for a period of time it appears to go down as low as 8%.
All I can say is, use ATK. Its just working great for me.

Thank you for this. It makes the problem clear to see. There are a lot of people saying things like "it all adds up to 100%" or "hey Android OS is high, but my battery life is very good".
As you say, we'd get much much better battery life if it weren't for this damn bug. Battery life can be good now. However with a 1650 mah battery, without Android OS wasting precious energy, it would be great...
Great summary!
More info
I have depleted the other 50% of battery so I'll post the values. The phone charged when connected to transfer the files. Well, at the end of the day, it looks like the that:
1. Voice calls drained 39% of battery for 3 hrs and 19 minutes.
2. Display is 2nd with 14% and 2hrs and 20 mins.
3. Android OS gets 3rd place with 12% and 1hr 20-this is the kernel running.
4. Android System- the one you bought the phone for- is pretty shy, only 9% . I repeat, here are all the widgets, Sammy updater, mail and so on.
...
Dialer is 6%, Navigon gets 8%, Cell standby - that's the radio FW- 5%
Phone Idle is the champ with 3% @ 31 hrs and 17 mins. That's the spirit.
Also, GPS status is eating 2,2% for every minute.
Bottom line: if it wasn't for the AOS, I would have had -see below( let's be real and give each process it's share so I'll split the AOS drain to get everybody happy)- before running for the charger .
1. Phone calls. 5.6% more battery- and 23 minutes more of talk time.
2. Display. 1.7% 22 minutes more.
3. Phone idle 0.9 % almost 10 hrs.
The rest of ~4% is shared for Wifi, Cell Standby and android system.
These numbers are valid for my usage pattern, phone calls all day long/ that's why i bought a phone for/.
I might draw some lines here and reveal some facts ( the values might be different according to usage pattern):
ONE MINUTE OF:
AOS bug drains 0.15%
Voice calling (I live on a good network signal area) depletes 0.13%
Display on is lower than calling @ 0.10%.
GPS could be chewing 2% when polled thoroughly.
Widgets and other Sammy crap are not scary at all. In fact, I find them pretty decent under this SW revision.
Maybe some will find these values useful.
Maybe we don't realize the impact of implementing a bad driver. For me, it all makes a lot of sense and annoys me more. Too bad we not on Icrap's ship, the news would have been all over the web.
One last thing though.
There are 2 main issues withSGS2: AOS and wake up lag. Never listen to any wise guy that says the lag comes from deep sleep and you should be lucky if you have it because it means the phone is SLEEPING and not eating away battery. I've noticed lately a trend in trolling this issue. I am confident that the guys behind this reasoning are on the same level with the guys that came up with Killing task managers and empty ram crap in Linux. And they even wonder why the alarm is not working after RAM flush.....
Wake up lag is a side effect of some nasty crap hogging the CPU's front bandwith. I bet any trolls here that when the lag is gone so will the AOS bug be ( at least AOS will be under Idle in %).
My wild guess is a radio issue somewhere.
same problem omg :S i hate this !! but phone is great !!
KG3 Report
Hi,
I have a new report to post, this time under KG3 stock rom. This time WI-Fi off whole time. I used the car dock for 10 mins.
1 day 7 hrs and 57mins from full charge to 15%:
Voice calls 2 hrs and 35 mins -37 %
Display on auto 2 hrs and 27 mins 20%
Android system 13 % Cpu total 10m 16 s
Android OS 9% 53 min 45 s
Dialer 6% C
Cell standby 6%
navigon 4% pops up,never used it
Phone idle 4%
Although it seems the AOS got less cpu with this, the improvement is not so clear. I almost talked 1 hr less with this one.
My android is 49% of 15 hour up time from last charge but the CPU time is only 2 hours 15 minutes for it. Hardly 49% of up time. Do you think maybe firstly there is no bug, its a bug with reporting not AOS usage time and that the phone hardware just eats a lot of juice even in standby. Just a thought. The battery lasts pretty good for the fact that its so small, there's an amoled screen and a dual core processor. Perhaps even in idle the hardware just draws a lot of power to allow a quick jump from standby to fully activated without any waiting around.

Could you post some screens?
Android system is 49%? the percents relate to the battery usage, not the time.
ALSO VERY IMPORTANT:
Dual core CPU should draw less power in standby/idle/sync. this is the idea behind dual/quad cores. If you have the time, read on how do they stack processes.
Deep sleep is not working properly. How come my WIN7 x64 wakes up in less than 1 sec from standby> win kernel is around 300 megs vs 17megs Android? It is a driver issue.

So instead of writing here, we should write to Samsung, correct? I hope this will be resolved soon, OTA update should do nicely!

Believe me, I've tried the highest official way there is. They keep blaming android/google. I even pointed them some apps that were using obsolete scripts and 4-5 ro.* that were hogging the cpu. All they answered is that is under revision. then somebody from the work asked me what the f*** is this communication about and told me to use the nexus S instead.
Here the results of a simple test I did:
KG3, CF-Root, 8 widgets, skype and viber, 2 e-mail accounts. The usage was roughly the same (mostly internet browsing, e-mail cheking and only a few voice calls 20min approx.) The difference is that in the first day I left the sync and WiFi on all the time. On the second day, I left both sync (including background sync) and WiFi off most of the day, except during the time which I was using it (browsing internet, updating market apps, checking e-mail, etc.) The result, as you can see in the screenshots below, is that with sync and WiFi off, I've got almost 26h extra of battery life (18h18min v 1d19h52min). So, for me at least, the battery drain is WiFi+sync.
Looking at the pictures, compare phone awake v screen on. With sync+WiFi, you'll see that the phone was awake many times with the screen off, whereas it didn't happen when the sync+WiFi was off.
Therefore, I think it is better to turn sync+WiFi on only when you really need it, and not all the time. That's what I'm going to do from now on.
Ah, no powersaving settings enabled in any case!
Android OS @2%
Still under KG3, nothing installed lately, nothing at all:
Full battery in the morning almost flat in the evening with very light usage- I on a sort of holiday ....
1. 16h and 2 mins it lasted
2. 57 mins of calling
3. 51 mins of display time
4. Android OS WAS 2 % running for a total of 3 mins
REALLY SAMSUNG?
I want my AoS back.....
i rooted the phone yesterday, screen on time was around 4 hours or so..10% drain per hour average with screen on-off.
freeze all bloatwares and aos went down to less than 10% (was in 40s).
will see battery improvement today.
after root, i still got the yellow rectangle at boot (havent remove it yet)..will it affect battery life? any input?
I froze the WIFI Sharing service and my phone went from dying 25% over 4 hours at work with almost no use (and WIFI off) to lasting all day, or not charging at night and lasting all night and through the next day.
Just saying.

If you don't understand that the yellow triangle ONLY means that the kernel you have flashed does not have the correct signature (i.e. it is a custom kernel) then you shouldn't really be messing with root at all. How would this be relevant to the AOS bug or to battery life?
What is your view on juicedefender?
Battery savers are pieces of **** that turn help battery life by constantly changing the device on something more like Nokia soap.
My Personal view on software that claim to help save on battery was/is as it is about task managers on Android... somehow useless mainly for a few reasons:
1. They interfere with running processes and I haven't seen one really optimized for the system. Some are behaving limiting the performance. Which isn't a good thing.
2. I found that even Watchdog is a drain culprit when it's running after a limbo limbo process.
I have seen this issues before, in PC world. 8-5 years ago, Sony was loading their Vaio series with so much crap that the laptops were slow as a turtle right from a start up. They failed to listed then and lost almost 60% of their market. Others reacted faster and gave the option of removing crapware ( mainly proprietary sofware and trial) when ordering [ btw,of course, anybody could do it by msconfig but few were willing to mess it...].
I can't get it why Sammy, HTC, LG won't offer a barebone/unified Android. We could all get what we need from Market and this is why we have the markets war.
I don't want my update service running in background, nor do I need email app from Samsung...in order to get them off my back I need to root, Edit a file and make sure I mount the right permissions( or BUY something to do it for me) and so on, most people don't want/can't root , not mentioning the longer the chain the more links likely to break, including the warranty is voided ...WHY all the fuss to stop something I don't want?
Microsoft hit the nail in the head with their approach to WP7 (except closing it like Apple). That's because they had to deal with screamers for 20 years and they have a clue about crap ruining an OS.
And yes, I am still waiting to see a dev coming out with a pure Android Rom on whole XDA.... for any device. They all add something to it....a tiny tweak or a tiny thing.
First of all, let me say thanks to Scott for all of his work on CleanRom. I know there has been a lot of discussion lately in his thread about battery usage. Some people are getting outstanding battery life and some people can't make it more than a few hours. I have been one of the people that can't make it more than a few hours no matter what I do. I did a clean wipe of everything before installing the ROM and have even tried to reinstall. The odd thing is my wife's phone does fantastic with this ROM. I finally decided to test things side by side lastnight. My phone should have had the clear advantage because I turned off all syncing options and froze any apps that had been downloaded just to make sure there was nothing running. Meanwhile, her phone syncs like crazy to facebook, email, etc and also has various apps running like weatherbug. I let them both sit overnight and after ~9hrs here are the stats I measured:
Battery % left : 79% (mine) vs 88% (hers)
Data used overnight: 75kb (mine) vs 744kb (hers)
Time awake: 3min 32sec (mine) vs 9 min 42sec (hers)
Time in Deep Sleep: 9hr 19mins (mine) vs 9hr 6min (hers)
Everything points to the fact that I should easily have more life left than hers. I am also attaching a couple of screenshots and the betterbatterystats files to this post. Maybe we can track down why everyone's battery life is so different. Tonight I plan to swap batterys between the phones to try to determine if my battery is the problem.
wow that's pretty good on your wife's phone but horrible for yours especially considering you turned off syncing.
I agree. I have no doubt that her phone could easily still be at 95% or more if I made all of the same adjustments to hers as I did to mine. That is why I am hoping someone on here with more knowledge about this stuff can help to determine what is going on.
It honestly might just be a faulty battery, I was having similar results with mine and my friend's phone, too. I tried multiple ROMs, Kernels, etc. But it slowly got worse and worse to the point that I would go down from 100% to 60% in little over an hour, doing nothing but listening to music with the screen off and auto-sync etc off. I bought a replacement battery, though. And this one is working just fine. You might just be having bad battery luck, or it might be your device, I know some people have returned their Rezounds because of battery life/heat problems, and the replacement generally fixes their woes.
so what did your betterybattery stats report?
Thanks for running this test. It would be very helpful to everyone if you could pinpoint this to a battery difference and I'm waiting to hear your results after the battery swap.
What helped my battery life most was to uncheck the box under "settings -> applications -> start automatically" It has something to do with a task manager. It probably wouldn't explain why your wife's phone does better but it could help both of you get better battery life.
bik- The betterbatterystats file is attached. I see a lot of activity on her phone but very little for mine. The only thing that stands out to me is I have alarmmanager waking my phone for 10 mins and she had it waking hers for only 5 mins. I am not sure exactly what alarmmanager is though.
HTGaming- Thank you for the suggestion but I have already done that as well. I think I have literally turned off everything possible on this phone because it is driving me nuts to burn through battery like this. My OG droid used to us 30% in a day max and now I burn through that in an hour if I am using the phone for anything at all. Pretty much the only thing I had running on the phone lastnight was 4g service which her phone also had.
Another thing you can do to compare the two phones is to install battery monitor widget to see what the drain is on the phones. I used to have decent battery life but ever since the update, it's been worse. The one thing I noticed is that now my phone draws more current when sleeping than it used to. The drain is consistently close to 300ma, whereas before it would be less than 200ma when sleeping.
You have to have the widget on for the monitoring to be active unless you change the preferences.
I swapped the battery's lastnight and here's the results. Hers is still clearly better than mine even though betterbatterystats shows way more activity on her phone again.
Battery % left : 84% (mine) vs 90% (hers)
Data used overnight: 279kb (mine) vs 498kb (hers)
Time awake: 5min 32sec (mine) vs 12 min 8sec (hers)
Time in Deep Sleep: 7hr 58mins (mine) vs 7hr 59min (hers)
Someone posted that they saw different PRIs on phones even after the OTA. Do your two phones have the same PRIs?
damnn thats just weird
Im starting to think that some Rezound batches are differently tweaked than others. My first Rezound had great battery, I would stream music for 5-6 hours on 4G and would still be above 60%. My last two however were completely horrible, on 4-5 hours standby it losses closed to 20% with lil to no use. Same settings/apps as my first Rez. I regret returning my first Rezound, it truly was the perfect phone.
There really has to be a reason why some come with a 3.8 V bat. opposed to a 3.7 V. HTC wouldn't just send out two different types of battery for no reason.
You are missing 1 key info in your analysis, which people always seem to leave out when talking about battery life. The screen on time. I see in in the graphs but it's hard to tell the exact number. Because of the 720p screen on our phones, that makes a big difference. When my screen is on, the phone uses up at least 600 ma/hr. That is conservative, usually it is more like 700-800. We'll assume 600 for now. That's 10 ma/minute. Based on the stock battery, that is 0.6% per minute. So having a difference in screen on time of 10 minutes will give you 6% difference in battery life.
i am also unable to go for even most of a day on one battery charge - and i have 3 extra batteries that were from ebay that dont work even that long...
i do notice it when the screen is on the most - yest i used the gps for an hour and a hlaf without plugging the phone in and my battery lasted about 3 hours after that and died....
very bad....
very interested to see if its the phone or not - great work...
I'll try to answer a couple of questions in here. I got very frustrated yesterday so I flashed an ICS rom to see how my phone did with it. It is equally as bad. This morning, I got into work with 97% life, checked my email for about 2 mins and was already down to 90%. I have the screen display set to 30% brightness too. I am amazed that people can used 2-3 hours of display and still have 70% battery after 10 hours. My screen at 30% brightness probably drains 2% per minute. I think tonight I am going to try to install one of the stock RUU's just to check and see if the OTA upgrade possibly didn't install itself correctly.
HTGaming - I will check the PRI's tonight.
Bluesnake - Both phones were purchased the same day so I would guess they are from similar if not the same batch. Both have 3.7 batteries. Infact when I first got my phone, I could have display on auto, sync everything every half hour, use the screen for random browsing throughout the day and still go home with over 70% left. Somewhere along the line my phone has developed some sort of draining problem though and no amounts of clean installs seem to fix it.
b5fan - Both phones were off the entire night. I think screen usage was maybe 10 seconds for both of them. They literally just sat there on the nightstand while we slept and mine drained 2x faster with nothing running while hers ran facebook, email etc.
I checked the PRI on both phones and they are the same. I re-ran the stock RUU tonight so I will see if that makes any difference. I highly doubt it will but I am running out of ideas.
I guess I was thrown by the screen shots. They both show some noticeable screen time.
the only other thing I could think to check is the email type, push versus pull, and the frequency.

The screen time was probably just from me getting all of the data off in the morning like the screenshots and battery stats. Her email was on push and my email was set to not sync at all. Basically she had a fully functional phone and mine was set to do nothing which is why the battery drain is so hard to explain.
I did run the stock RUU image lastnight for my phone. I put it in airplane mode overnight and it was at 97% when I got up which is a huge improvement. I took it off airplane mode at 6am today and when I got to work at 7am, it was down to 90% so I guess I am in wait and see mode now. I have no email accounts/facebook accounts/ or anything else setup right now. It is only the stock image so there should be nothing draining battery today.
I can confirm the phone is no better now after the clean RUU install. Let it sit overnight and it was down to 80% this morning. I did not even setup any email accounts or download any apps yet. This is just the stock image from verizon.
So I have a Galaxy S III which I absolutely adore. Some time ago, though (2 weeks maybe?), one of its biggest cons - the battery life - disappeared. Earlier, I could be sure that the battery held around 3 days of my regular usage (some emails, games, web) being left with around 20%. Some time after the update to 4.1.1, the battery started to have good and bad days - sometimes it holds just as it used to, other time it's a half of it (15% after 1 day and 7 hours with no games and almost no web? Come on!). I thought it was because of Google Now so I disabled the geo-locating options but it's no better. When I go to the battery usage in the menu, it shows me that Android takes 38%, idleness 24%, the network 21% and system core 6%. The screen or Wi-Fi are just 5 and 2 per cent! What's wrong, then? What should I try to do to get back to normal with the battery?
I tried all of the battery tricks in this forum to get manageable battery life, but I could not make it to 3 pm no matter what and I refuse to cripple my smart phone any more - this was enough:
Wi-fi off
Wi-fi-calling off
Volte off
Location off
Display auto
Email sync 1 account - 30 min
The phone would deep sleep and my SOT was not over 3 hours ever- but I could never make it much past 3pm on a normal day. Maybe a got a bad phone, but I remorsed on the last day possible.
I have an M9 and am getting longer battery w/o all of the crippling above. Should I try an S6 or another S6 Edge? I love the phone and camera but accept TW, should I wait for the G4?

Just an FYI, I have both the M9 and the 2 of the S6 edge phones. I get about 15hrs/3 hrs SOT on S6, my wife gets almost 20hrs w/ 5 hrs SOT on hers! We use the phone in different ways. She is on facebook and texting. I am on email, texting, remote desktop & games. However, on the M9 I was getting about 30 minutes more than S6. Not a huge amount but it was slightly more. However, after using the M9 for almost a month and now having the S6, I'm returning the M9. Mainly due to the camera. I have kids and S6 is a much better spontaneous camera for consistently capturing a good image. Plus the screen makes the M9 look pale in comparison.
Did you try a Wipe Cache Partition and Wipe Data/Factory Reset under Recovery Menu? A lot of people have done the reset and the phone is getting now almost double the Battery life they were getting before, just by doing that, plus all the little tweaks about VoLTE and Wifi Calling and other bloat you should disable anyway.
Mine has giving me nothing but great battery life averaging 5.5 SoT since I git it on the 10th, BUT, I knew there was an update pending so I turned on the phone the first time, skipped all initial settings except the Wifi, it downloaded and installed the T-Mobile Update and then immediately I went to recovery menu and did the wipes then set the phone for the first time, working great since day 1.

Yes - I did that and it did not really change much. I think that I must have had a bad one...
You can make of this what you will as I have no idea if my singular experience plays out but I traded a white Edge in for the black color Edge and the new handset has much better battery life. Also the fingerprint scanner worked perfectly from the first try on the new handset and was about 50% on the white phone I turned in. And yes I tried all the suggestions for improving the fingerprint detection, watched the youtube videos, no luck. I stopped using it all together. I did all the revert, reflash, reset, wipe, turn off every thing under the sun, etc for the first handset to try and improve battery life but no joy. I still only get around 4 hours screen on before I'm down to the 20 percent range which isn't great but enough for me. It also matches my expectation for what is nowadays a small battery in a heavily bloated phone. My first handset was in the upper 2 hour to low 3 hour range in the same use with no wake locks detected and deep sleep occurring. Keep in mind I've been on Android from the very begining so I'm not unfamiliar with hunting down battery hogs, wake locks, etc.
I had planned on giving this one a go and if it was the same as the first one moving on to the next thing or else keeping it if it wasn't. Turns out I'm keeping and I'm glad, its a pretty little sucker...
ok- I am going to try another S6E and see if I get one with a good battery

Also, please try to investigate what apps may be draining the battery. After 16hrs., I'm at 47% battery life. I think that's pretty good.
Thinking of upgrading to the Samsung Galaxy S6 Edge but worried about that the battery life won't be the same as my Note 4. I normally got around 4 hours on screen time with a charging time of 90 ish minutes, does the Samsung Galaxy S6 Edge really beat that?
Share you screen on time screenshots with your S6 Edge. Does having the curved screen always on information stream drain your battery? What's your screen on time with bluetooth turned on most of the time,
Does 15 minutes of charge really provide you with 2 hours of watching HD video, does it have to be the default player or can it be any, like MX Player
I'm just gonna leave this here.

I always get 5hrs 40 mins watching Netflix on data so yeah it should. Most people get about 4hr 30 mins and up.
Well, i am one of those that never get the Screen time people show they get, i guess it's my brightness settings or that i leave everything on, bluetooth, nfc, wifi, gps etc..
I have the phone for 2 weeks and never went under 40% of battery , but at 40% i was with 8 hours on battery , 1h 28 min of screen on time. So i have the feeling that for me wont last over 3h of screen time. I might have some high drainage on stand by thought , wakelock or something. Today i charged my phone and went for a bike ride , so i barely used the phone, right now i have 82% of battery - 5h 45 min on battery with 19min screen on time.
Just sharing , not saying the phone's battery sucks. For me it's fine.
Depends on lots of factors. Some people have really bad battery life while others have awesome battery life. I've never had an issue with regards to battery life and I recently rooted and swapped to Edgar's debloated rom. I am using Kt kernel on stock clocks with undervolting on big and little cores of around 75. Unfortunately I got stuck with some bad binned chips or I would have under volted even more. Usage consists of Netflix, tapatalk, reddit and Facebook (web), and texting. I'm not a gamer but I do play clash of clans for about 15 minutes a few times during this cycle.
I can't attach my photos for some reason.
Sounds awesome. I would love to get around 5 hours of Screen on time with Bluetooth on and connected to my Gear S. I would mostly be using it to browse the web, play YouTube videos and download large files often. Do you have to give the battery time to adjust to your habit to get the maximum amount of usage.
The battery takes time to settle down. I think 4hrs sot should be possible for medium use. This is what I've always got with all the Samsung phones. I used to get near 5hrs sot with note 4. I've only had the phone a few days now and the battery was very poor to start with and used to get soooo hot during charging. It seems to be settling down...else is going back. ...I'm still trying to get used to the size lol

I find that having wifi and mobile data on drains battery like crazy... this is my first android phone and on my iphone i could turn off 4G and stay on 3G to save battery but not an option on the s6 :/
