So I've played a bit of Sherlock Holmes over the last 2 days trying to monitor the AOS bug and how exactly it affects everybody.
First of all let's start with a graph:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
First of all we can divide the whole time-line in 3 parts:
T1) From beginning to the second bar of phone usage
T2) From T1 to the infliction point
T3) From T2 to the end
In T1 I had the phone as such as I always had it for several days and nothing special to report there, AOS was taking up up to 3h of CPU time during that 9h period.
Between T1 and T2, I upgraded ROM from Cognition 1.20 to 1.30, and left home (You can see where Wifi is not on) and got back several hours later. Now this is the most important part as what I've noticed over times and times again, the AOS bug doesn't come up when there is no Wifi or Internet connectivity, fine and dandy as long as I'm not home (I also had no 3G for that period), as expected. AOS gains just 1-2 max. minutes per hour in terms of CPU time. At the middle of T2 I get back home, turn on Wifi and so on.
Now what blows me away is that AOS continues to just use little CPU time for about 7 hours at which I'm home. Everything works fine, I have not changed anything to grant any difference in usage.
Now sometime in the night I use check on the battery again, as I've done over time the whole day to keep an eye on the usage, and this time, AOS goes nuts as you can see in the drop in battery level after that "infliction" point. AOS was at a little over 4 hours and something at that point, and one hour later it was basically at 5 hours. I said **** it and went to bed.
After waking up and noticing my battery level dropped about 15%, I checked up on AOS and what do you know, it's at 7-8h CPU time now.
In the morning I chatted for a bit and some light browsing, I let it plugged in for a bit and that was it. At the end of the graph AOS is at 9 hours of CPU time.
To the point:
The Android OS drain is real and kicking, and it makes no sense what so ever. There is no correlation to the usage of the phone. I found no correlation to the applications I'm using. Apparently there's not even a correlation to if you have Wifi on or not, since it worked fine for me for a while.
And its effect on battery usage is also pretty much real: As you can see I marked the average drain curves over the 3 periods and you can see clearly the similarity in usage between when the AOS bug is alive and when not, a 26° curve vs. a 16° curve. So what it means that flat-line idle usage is increased 40% by this one bug only. [And before anybody tries to reply on the degree of the curves, it's only relative to my usage in the screen-shot and irrelevant for anybody else.]
I even plotted a curve over the whole time too see what it would have been if AOS usage were to be sane. Result: At the end I'd be somewhere around 60-55% instead of the 25% I am now. Of course what I did is not accurate at all but even if I'm as much as 10% off it's still a huge difference and you can see the point.
Some remaining remarks:
People say it does not matter that if your phone is idling or not being much in use, having a high AOS % is normal since it needs to sum up to 100% and that's why it happens. Get your head out of your asses and think for a moment. Firstly, of course does AOS % go down when you're heavily using the phone, because when you're actually using the phone you're using more power than AOS would ever be capable of draining when it's in Deep Sleep. Secondly, when idle and in Deep Sleep, nothing other than Phone Idle, Cell Standby, Wifi, and Android System (Under which everything that runs in the background is packed) should be using anything. A percentage is calculated from absolute values, and when it's high, its not for nothing.
As for what I'm actually running on the phone: Nothing other than Skype and Trillian, and I've already checked that those have no effect on AOS usage at all. I have no widgets other than the clock in the lock-screen. I removed all of the Samsung apps and most of the services. I have no push email or anything related running. I disabled all syncing. If I would go even more bare than now I'd be losing usability. I've tested this with a dozen different Kernels and ROMs and it's not related to any of those. (SpeedMod Kernel makes AOS not appear anymore because I believe it disables the monitoring capability of the system to actually record the usage, battery life does not change, but I've yet to do a extended test so don't take my word on it)
Well that's all for it now. I just wanted to do this rant since I felt like throwing the phone against the wall last night when it suddenly ate up 5% battery inside of an hour. So annoying when everything else in the phone is perfect.
First, that's a fantastic bit of predictive analysis you worked up. I'm guessing you do a lot of number crunching in your day job.
I posted the following in another battery life thread. I'll post it here too. Do you disagree with my theory about the lack of a common denominator pretty much guaranteeing there will be no common solution?
Consider this:
1) Every phone leaves the factory configured exactly the same way.
2) People connect to different carriers ranging from large/advanced to small/outdated.
3) People use different routers to connect to Wi-Fi and spend varying amounts of time connected.
4) People use stock ROM's and cooked ROM's
5) Some people use CPU tools, memory managers, task killers, battery monitors, and some don't.
6) People use different e-mail clients, e-mail providers, different sync settings and send/receive different volumes of e-mail.
7) People use social apps differently with different sync settings.
8) No two phones have the exact same set of apps loaded on them.
9) People use their phones differently with different amounts of talk time, display time-on, CPU usage, and downloading time.
10) People use different SD cards.
Now, with all of that said, you tell me how any discussion on this forum is going to come up with a single "Holy Grail" solution to better battery life? If there's no common problem how on earth can there be a common solution? If everyone on the forum was getting ****ty battery life I'd say there's a chance of a common issue. That's not the case. And the never ending circuitous conversations about battery life that take place are inane because there is no common base to build a meaningful discussion on.
Funny my AOS never had to go greater than 10%, checked with my neighbour too. we got the same phone on the same day.

Well I don't know the context of that post you wrote but you're diversifying the problem too much if you bring up all those points. My point and this thread is about the lone AOS eating up battery life and having such an impact. That's why I had almost nothing else running on the phone as to try to isolate it as much as possible and actually bringing up the common denominator.
For me half of those points don't even matter, and at the end of the day the most-common denominator is a) Gingerbread b) Samsung drivers. I'm pretty new to the Android ecosystem as I didn't have any before my SGS2, so I don't know that much about other phones but one buddy of mine has a Desire HD and has the same problem with high AOS usage, so that logically would mean it's a Gingerbread issue. I have not heard of it on anything running Froyo or earlier.
Fact is people who post on those threads about battery life and having AOS showing up at such a high percentage, yet accept it and even say it has amazing battery life are disillusioned as it could be even much better if this one thing alone were to disappear and go away. Anything else using up battery in your list is what I would call actual usage of battery life, as all those things listed have some kind of measurable effect in usability and bring something to the table, as opposed to this, and that's why we call it drain or waste of battery.

Exactly people like you is what blow my mind. What I've noticed that when not using Wifi or 3G (And after my testing I'm not so sure about 3G anymore) the AOS usage is very low, so maybe you're falling into that category of people?
Thanks to the first 2 posters for their analysis in particular the OP,i think most people who on here who have a GS2 share your frustration, i have noticed that the leaked 2.3.4 update which was said to solve the AOS problem has failed to do so, well not exactly the AOS has gone down slightly but is certainly still a big issue for lots of people.
Like the OP ive tried to do some tests and try out various things but im still as much in the dark about what really causes this excessive battery drain,i too run Cognition ROM but it appears every ROM whether it be stock or custom suffers from this AOS drainage, ive not come across many who haven't experienced some sort of excessive drain with AOS.
I am going to look into this Kernel that the OP mentioned and give it a go, nothing to lose, wasn't there a big thread on this forum relating to AOS too, hopefully someone will come up with a viable solution sooner rather than later so we can all have better battery life on our GS2.

I'm another one of them, although I think in my case it may be because my usage of the phone is so high the Android OS is mostly hidden under the overwhelming weight of Display

That's why we need to stop using % to compare it and actually share the CPU runtime of the package, so in that way we can actually compare apples to apples. And it would be helpful to know how you've been using your connectivity in relation to that, as again, I repeat myself, it doesn't seem to happen when not connected to anything.
Thank you for the anaylsis. My findings mirror your own. Android OS bug runs rampant on wifi. However, on 3G or HSDPA, it inflicts much less damage, so I keep the phone on 3G or nodata mode unless I want to download something big.
What's sad is, I have tried every kernel, every ROM here, including truly alternative things like Cyanogen nightlies. This bug is always there. So I think it lies in Samsung's drivers package, which is common on every kernel. Until Samsung rewrites the drivers, especially the WiFi driver, we'll never get rid of this.
Disgrace
The fact is AOS bug is there, all time, sometime it's very prominent and sometimes not, doesn't really matter if there is any connectivity or not. Versatile bug to a versatile OS I guess. Don't like it.
Regards.
This bug is getting really frustrating so I wouldn't mind ranting a bit about it.
This is my battery stats yesterday and the only thing I did was a couple of minutes of web browsing. (I'm using stock GB 2.3.3 KE7)
Not sure what to make of mine, i cant really tell if i have the bug or not

You don't. 12m over 10h30 and with Wifi on all the time is excellent...
Can you please share what you did to your ROM / versions and what settings you are using?

Villain 2.1 (kg2 base), Ninphetamine-2.0.1 kernel, kg3 modem.
Well, from my testing Android OS bug is most likely related to wi-fi, at least on my phone. The whole story is this. Used my phone for about 3 weeks without ever connecting to a wi-fi network. Everything was fine Android OS never showed more than 7 % up to 10 %, phone being idle or in constant usage. Connected to the same wi-fi network for about 2 weeks Android OS stayed the same, nothing unusual. Finally arrived to my home place and connected my phone to my personal wi-fi router and fun began, Android OS started reaching even 50 % while being idle and up to 25 % when using the phone. So in my opinion it must be related to routers' brand/class. I gotta mention i had the same apps installed in my phone for the whole time, stock android 2.3.3, no root. That's my story. Believe it or not , it's up to you. It might be related to tons of other things, but that's my personal experience.

I just tried this via tethering my router via my laptop and using that as the access point via Connectify. Didn't change anything.

Wish i knew what kind of router was used in the wi-fi connection that i connected to first time. Obviously Android OS went nuts after connecting to my personal router. Will try and see how the phone runs when i connect to the router at my office, cause it's a different brand. The only difference i can think of is on the first wi-fi network i was connecting 3-4 hours a day, while at home i'm always connected to my router, 12 hours a day average. Wonder if Android OS would decrease % if i use wi-fi connection less.
Even when it is the router - it could be fixed.

Great study. I would like to add that the Android OS process could be including anything non-app related. So if you have the market doing a background check to see if the apps are updated, then that could be showing under Android OS since the actual market app itself is not running. Same goes for your mail apps etc. I suspect that as long as there is background sync or notifications happening without the app in question running, then Android OS goes up.
Here is mine from last night before bed until now (10:19am). Running stock KG3 2.3.4 with CF-Root KG3 kernel. Don't mind the battery spikes and drops, I just cleared the battery stats last night.
Here's mine.
It was used heavily from 1 am to 3 am, with Dolphin HD and music playback. Then I was asleep from 3 am to 11 am, with the app "Sleep like a droid" on. It's an app that monitors your movement using the accelerometer to determine what phase of sleep you are in and thus the best time for the alarm to sound.
Wi-fi is on all the way.
Not sure if I suffer from the bug. AOS usage is little over 12%, although CPU time itself seems to be low.
ROM: Lite'ning 4.1
Kernel: Ninphetamine-2.0.2
Hope this helps!

Ive spent the last few days fiddling and testing stuff to increase battery life. Here is what i have learnt...
(Im running R2BA026)
Firstly, personally i do not want to lose any functionality/performance in order to gain battery life. I think that if you are going to spend the money to get a phone with awesome hardware it should be able to run at full whack.
This guide will not be useful to all, but hopefully it will be handy to those in my situation.
This is a guide for what i have found to be the best compromise between battery life and user experience, with the emphasis being on user experience.
My specific goals are:
- I do not want to lose any performance i.e cause any slowdown/choppiness.
- I am only looking for a 24h battery life as i can charge every night.
- I want to be able to use my phone without worrying about battery. Specifically I never want to think "i shouldnt do that it might run down my battery". I should be able to use all the features on my phone without questioning if i can afford to.
-=-
In my experience using a task killer resulted in only minimal gains to battery life but it meant that opening up apps could be a lot slower and apps could be choppy just after opening them.
Additionally the idea of setCPU is a good one however when coming out of sleep or opening an app it takes a little while to get back up to speed. This also causes choppiness. Personally I find lag/choppiness a real pet peeve, it irritates me alot, so I do not use setCPU either. It is true that with careful set up the lag can be minimised but then the battery life gains are also minimal, so I choose to keep full performance and dispense with setCPU. Bear in mind that the hardware platform is already very efficient and well optimised so a software solution will pretty much be a straight trade of performance for battery life.
-=-
With those two common options out of the way, what else can be done to save juice?
Well generally the biggest consumer of energy is the screen. The simplest option is just to turn it down to minimum brightness, but in my opinion that is not a good solution, its too nice a screen to have dimmed all the time. Thankfully the auto-brightness does a pretty good job of keeping the back light at a good level. It can be a bit disconcerting if you enable it when using full brightness as the drop can seem somewhat dramatic but don't let that put you off, give at 1/2 a day or so and you wont even notice.
Other easy but important things you can do are turning the screen timeout to minimum and always turning off the screen (power button) as soon as you are finished. They are tiny changes but really do make a big difference.
-=-
Onto wifi...
I think there may be a bug with the firmware because if I disable wifi I get a HUGE increase in battery life when Im at home. I have good 3g coverage here and a 3GB allowance so I only need to turn on wifi when Im browsing the web or market, seeing as it takes seconds with the widget this option suits me fine.
I suspect that when the phone is connected to wifi it doesn't sleep properly so drains very fast.
Only turning on wifi when i want it made by far the biggest difference to me, and as it doesn't affect my user experience in any appreciable way I am happy to do it.
I think its a good idea to mention app/widget updates and refreshes here, personally i have all my widgets and apps set to refresh only once a day, that suits me fine because I can refresh them all manually very easily if I want to to be absolutely up to date and I'm not a twitter or facebook addict Most of my widgets are news/article based so once a day is perfect.
-=-
GPS, again this is rather obvious, if you don't use it, turn it off. Personally i use latitude so I have it turned on all the time. Android seems very good about only using it when it is needed and the phone seems to get a fix very quickly so in reality it doesn't spend much of the day being active.
Same goes for bluetooth, although I don't use it so it stays off.
-=-
Nothing i have said here is particularly revelatory mostly common sense but I have always had battery issues often with the battery lasting ~12 hours before asking to be charged.
Updating to 026 made a big difference and following these rules means my battery drains on average 2-2.5% an hour under normal use.
Normal use for me:
-Wifi Off
-GPS on (With latitude widget)
-Gtalk always running
-3 news widgets + timescape
-frequent texting
-moderate calls
-frequent fiddling
The phone is very very snappy, everything apart from timescape opens as near to instant as makes no odds, the phone is a pleasure to use. My battery life has comfortably doubled without the use of any apps or any loss of performance.
Mission Accomplished
Thanks
Cheers for that. Very interesting .
I definitely agree about the task killer apps, the OS does a perfect job at running itself!
One question, Am i correct in presuming you have 3g always running? Network mode set to GSM/WCDMA preferred? Ive been afraid to do this as i have it in my head that 3g eats up my battery for fun! I'll have to try it out.
Thanks again!
I bought an extended battery for my X10 the sloping sides stop it looking like a brick. The G1 always looked like a brick with an extended battery but the X10 sloping sides do serve a purpose.

Yep, thats correct With the 3g on it seems to stay in 2g when sleeping then switch to 3g when you wake it, you can see the change in the status bar about a second after waking. Pure speculation though ...
Well, let us know how you get on with 3g active all the time

Some additional tips based on my personal experience:
-Using a third-party task launcher helps too. Some may not agree, but it works for me.
-Use a third-party digital clock widget instead of the stock one. Again, YMMV.
-Use a third-party(AGAIN!) MP3 player instead of Mediascape. I'm using Meridian, and notice an increase in battery life when playing MP3s.
I like having some control so I run task killer but there's no auto-kill enabled and if I know the phone is just going to turn it back on in 5min, I don't bother killing those apps. Maybe I should just remove it altogether, but it seems convenient to be able to kill an app at will (I do it with windows sometimes).

I think the reason why you find that the stock one drains your battery is due to the "use network provided values" being checked in the date and time settings.
Interesting article. I am running 024 and my battery is life is poor. I managed to get seven hours use yesterday after a full charge. My usage throughout the day wasn't anything too crazy. Where I work I get only a standard signal (no 3G). I seem to get a better battery life.

I agree battery life is horrible. It makes me really miss my blackberry.
Even when battery life is low, charging it takes FOREVER, not to mention if you plug it in and play with it at the same time, it charges even slower.
My Blackberry Tour charged fully in what seemed like 45 mins from less than 10% batt life. I know they are different phones, but it just really sucks to me.
I'm debating going back to a blackberry now. The X10 and other android phones (and Iphone), are more toys than anything else.
/end rant.
hehe sorry
Thats odd, my phone charges pretty damn fast, just a few days ago i was pleasantly surprised that it charged from completely empty (id forgotten to charge it) to ~80% in less than an hour.

Quite interesting for me, I decided to add some statistical experiment about it.
Under my situation and environment. (I won't go in detail, sorry about that)
With SetCPU were 2.32% per hour without any usage.
W/O SetCPU were 3.18% per hour without any usage.
or approximately 7% maximum saving per day time. (for me)
My SetCPU only effected sleep state.
Not a big deal but still significant different, but it could survive for whole day anyhow.
I'm more interested about Killing app. I might try after this as I see many argument about it.

Ohh figures, good stuff! Always better to have some numbers to work with.
Do you not find that for a few seconds after waking up the phone gets choppy?
I would definitely be interested in seeing the stats with a task killer

Yup, with SetCPU for sleep state, it was 'choppy' for a few sec, mostly effect lock screen and screen switching.
Hey guys. Battery life honestly, is the most important thing when owning a smartphone. Everyone gets different battery life apparently. Some are great!! Some are.. well..
Anyways, my whole point of making this thread is so that we can discuss our various battery lifes. See who has the best. Who has the worst. And why we have such differences! Maybe we can make solutions and we can all have great battery life.
Please include what ROM your running, what kernel, if your overclocked, and little things you might find suitable to add.
For example this is for me:
I'm running Acer liquid ROM 1.1 with pershoots latest .32 kernel. I can get maybe 8 hours out of my battery with extreme mild use. I'm currently trying to recalibrate my battery with the help of bongz ( thank you so much!) I have my screen usually dim, nothing syncing from what I know of, bluetooth never on, gps never on, wifi only at home.

I'm running GingerVillan 1.5.
Battery life on standby is great - probably around 1-2% an hour. However, when I start using the phone, that drains QUICK. Generally I get around 12-14 hours out of a full charge with mild usage, including Phone Calls, Texts, 1-2 rounds of Words with friends, etc. WiFi is always off, bluetooth is off, GPS on. Stock kernel, newest radio near as I remember. Facebook and Google are the only two accounts.
I previously had a Vibrant that seemingly got better life - with mild use I could easily get 18-20 hours. However, having a keyboard and working GPS is worth the charge every night. The G2 could have gotten a couple hundred more mAh battery, if you ask me.
im running cm7 nightlies
my battery life is pretty good when not on. maybe 1% every 2-3 hours when off and in my pocket(set to absolute minimum via setcpu). with mild to extreme use i get ok battery life of about 4 hrs (starting at 80% usualy). im overcloacked to 1.8ghz ut have it set via setcpu to max out at 1.1ghz. i have gps always off, wifi always off, brighness to auto, and bluetooth off.

Hm, I might consider upgrading radios. A lot of people are getting great battery life because of it.. will se.
I have never got more than 8 hours with my vision ever. Maybe because I have the old radio?

Hey,
I think there are too many variables at play here for this to be any use, but here is what I am running.
ROM: Virtuous 1.0.1, OCed to 1GHz using Virtuous Standard 2.1.2 Kernel
Radio: 12.18b.60.140eP_26.03.02.26_M
Build: 1.85
Brightness: Auto
Sync: Google, Facebook, Weather
Wifi: On at home, school; Off all other times
BT: OFF
Data: Always ON
Usage per day: 50-100 texts, 3-5 voice calls, 1-3hours of data/games
Current battery level including standby time and usage time is 57% after 6h 50m.
Good luck on the analysis!

Sorry, but battery life threads/posts are always such a joke. So many things effect the battery life that it really isn't as easy as just posting your ROM and Kernel and call it a day. Every single setting in your settings menu, every app you run or have installed, screen on/awake time, BT/GPS/wifi/3g/4g connections, and even just general areas that you use your phone pertaining to their signal strength can effect what your battery life is. Unfortunately, there really is no way to figure out what the "best" battery lives are. It really takes your personal preferences and some of your own tinkering in order to get your configuration just right. You can go into any given custom ROM thread and find someone claiming 30hrs of battery life.
Sorry to be a downer. I (personally) just get really tired of people posting battery life screen shots because there are an extreme number of variables that affect it. I think it gives people false hope of looking to switch to a completely new ROM or change huge numbers of things and expecting to double their battery life.

Can you go to about phone and check your radio?
Fellas hear this, with 2G constantly on only, the radio is using 47 percent of the battery. Do you guys find this normal at ALL? I'm running CM7 now with latest pershoot kernel and this damned .27 Radio which I am seriously considering removing for good.

It's that Hutch one from Australia or something. This one here: http://forum.xda-developers.com/showthread.php?t=959488
I just noticed that the battery life of my DesireZ is greatly dependant on where I am.... I have vacation now and I was mostly at home for the past three days the battery was still about 40% charged this morning so after 2 full days with moderate use, reading an Ebook, playing a game, wifi constantly on, exchange mail on Push and Gmail on push, with standard rom.
when I am at school the battery is often almost empty at about 5 pm...
maybe because of the bad coverage at school?
I don't know if anyone else really noticed, I seen it mentioned in another thread but not enough, if you don't use the wifi calling app, DELETE IT! I have noticed much better performance and battery life after getting of that ****

Can some one tell me their usage with 4g on all day and moderate use?
Ive begun to get lazy turning 4g off so lately im getting 10-14 hours usage before the battery is dead not using wifi at all ( work days no wifi at work). moderate use maybe 20 mins calling 20-30 text up to 45 min facebooking. nothing too much,
On nightly #29 no pershoot since i am lazy to update to newest nightly and newest pershoot only works after #30 and overclocked to 1.2ghz
I still don't get why people care about battery so much with g2. I got 2 extra battery and an external wall charger all for 10 bucks on ebay. why not use android to its full potential without ever worrying about battery for $10?

It's a hassle to take off the case (in my case an Otterbox) every time to swap the battery out. Added with the looser hinge, you might accidentally snap something that you don't want to. Would rather have one big battery than multiple smaller ones.
Understood. I don't ever use protection covers. Didnt even know tHere are the kind of cases not interfering with keyboard pullout...

I want the Mugen battery, my G2 has been quite crap battery life for the past while, I wonder how much this one will help
No complaints here.
Just thought I would throw down my stats as well:
I can usually eke out a good two or three days from my G2. Some things of note: I'm on Wi-Fi with UMA at home, T-Mobile's home network (EDGE) when I'm in the town in which I live, but as soon as I leave town and head towards my place of work, I roam on EDGE all night (with roaming data always turned on) until I get back home. I don't think I've even seen the 3G or H indicators light up on this thing. Got to love the rural life. I leave Wi-Fi always on, in case I find new networks, I leave GPS always enabled, since it really only activates on Google's home page anyways, I use the 30% brightness setting that is the default 'low' setting via the HTC brightness widget, and Auto-Sync is always enabled (Facebook, HTC (weather once per hour), Google). I use the default 1 minute screen timeout, and I use the lockscreen that comes with Poweramp (which I use to listen to music on my drive to and from work via an FM transmitter.)
The capture below shows 2d 14h 2m 30s since being unplugged, at 7% remaining. I use Virtuous 1.0.1 with the stock HTC kernel and the stock T-MoUS radio. I am also using the stock HTC battery that the phone shipped with. I don't feel the need to overclock, as my last phone was a BB Pearl, so this thing is light years faster already.
The only time I really eat up my battery is when I play Wordsmith, because I'm always staring at the lit screen trying to make fancy words.
And while you're right, there are way too many variables when it comes to battery life and usage and signal strength and what have you, it amazes me just the same that others are fine with 8 hours of battery life and choose to carry around extra batteries. Sure, you have a mobile Linux box in your pocket (awesome!), but that's also why I keep a desktop PC at home. To each their own, though, no harm no foul.

So i'll cut to the chase, Battery has been ok with stock rom, after freezing the **** out of some apps, BUT, with VillainRom the phone is working perfect + battery life is amazing.
What is amazing?
53 Hours and 30 minutes since full charge.
I did charge it in the car for very short periods while using GPS and screen on full brightness.
How was the phone configured?
- Wifi/3G Data on at all times
- Push GMAIL and What'sapp
- Screen Brightness on full and the "Adjust screen power" option ticket off.
- Lookout installed and running in background.
- Bluetooth always on, not always connected though.
- 3 Hours of display usage
- 1.5 Hours of calls
- Some gaming, browsing etc.
Don't believe me?
Here are screenshots!

Anyway still don't understand what's good about this battery stats ...
@sumeshd,
You know, I don't get money from Samsung or anyone else for posting this? Why would I lie? Anyway, believe what you what, I really don't care that much.
I'll just say again, brightness is @ FULL.
3 Hours, is not ONLY, that's my usage, and you don't have to like it or not.
@bilboa1,
If I wanted, I can charge the phone almost 24/7 I got a charger my car, at home, at work, and even a portable solar one.
The charging peaks you see are mainly USB file transfers for a few minutes, and the long ones are around 30 minutes while driving with GPS + Screen at full brightness.
So the consumption on those moments is rather high, which means the battery isn't charging all that much.
@Mittaa,
You take a 4.3" Smartphone that does everything, and get 53 hours out of it, it's not enough??
if the little charging peaks were not there i'd still get around 46 hours from the phone, is that not enough???
Anyway the information I posted was to help people who are trying to choose a ROM, chose this one, or other people who are having battery problems have a reference.
eitama dont bother posting let this thread die please .
Two reasons one you will find certain users insist you have poor gps yellow screen bad battery life etc . Not worth bothering with if you are happy with your phone .
Reason two is a bit selfish as posting VR great battery life means we are going to get hundreds of numptys posting in VR rom thread who wont read and cannot follow instructions .

Nice to hear that your happy with your phone ... i'm happy too
I also understand that this is way better than your old desire HD (same for me moving from my old HTC Touch HD)
But I can't understand what this have to do with "whatever Vanilla Rom" ...
Lots of people can get this kind of battery live using stock unmodified, non rooted SGS2!
It could be very usefull if someone made a exact compare between two SGS2 running different ROMs.
First same configuration (screen brightness, auto update, widgets etc) then full charge.
Then 15 min GPS (same route), 15 min browsing WIFI (same websites), 15 min gaming (same game), 15 min talking (same person (sorry bad joke)).
Al together 1 hour of heavy identical usage.
Finally screenshots of battery stats and post here on XDA so we all can clap our hands for the best bettery saving ROM of the week
Well I tried to drain the battery on vr playing games etc to calibrate, and struggled, like noonski did.
I could drain stock rom with ease, but can't do it nearly as easily on vr.
The general consensus from reliable members like nobnut and jje seems to concur with it being better

well as I said I have tried all the roms..
I have tried vr4..for many days..it gave me 9+ hrs..
good u r supporting vr but not good that u r filling threads with "anything"
this is my battery with batista70 rom..and I m happiest with it..
PS: note the screen wake time bfor commenting..(its awake most of the time bcoz my heavy txting and use)..
and I am on 3g/h network with data active all the time..
this is the best I could get till now(with my usage)
no hard feelings..
People seem to be getting time between charges that vary wildly, but for me the biggest indication of battery life is obviously 'display on' time, and this seems to be roughly the same for the vast majority. Best I've seen so far is 4 hours, and that was mainly 3G/HSPDA browsing. My most recent however was slightly over 2 hours with VR 1.4, and again that was mainly browsing with data.
So while a screenie showing over 2 days may look impressive, it's how much actual use the user got that's important. The post above that showed over 6 hours was certainly impressive, but how much 3G browsing was done? How many 3D games played? GPS? etc etc
<shamed> - sorry for long post!!!
@ OP - you had a few minutes under 3hrs of charging. That is in excess of a full charge of the battery! And a total screen of a a few hours.. Nothing impressive at all. Saying you had on GPS and screen on full brightness negates the charging is just silly. It is usage, and usage is what we're interested in.
@ mittaa + Zedwings: Completely agree with both. Even display on (IMO the most accurate comparison) is a long way from the full truth for comparison in testing and a very fixed test environment would be needed to test a pattern of usage. I started to think about this like mitaa suggests (and when you do, you realise it is virtually impossible to co-ordinate without resetting back to factory) and there are still variables.
And anyway, it's kind of irrelevant at that point. You wouldn't consider doing it unless you're battery life is not meeting your hopes or needs. but your usage is your usage and you'll be happy or not.
Unless you are prepared to compromise on screen time, game playing, widgets, sync settings, live wallpaper etc, then what does it matter? You must find the balance between battery life and customisation that YOU can live with.
Personally, I do this by running my phone in 'full fat' mode. All radios on (this inc. GPS), synch on full, screen set to about 75% (no auto), the widgets I want, high spec live wallpaper (like Galaxies!) that make my £500 phone look like a £500 phone. I settle into my daily usage pattern, charging whenever I need to charge. This is why I bought my phone, not to immediately turn everything off and play the 'longest, littlest' game!
After about two weeks and this has settled into a fairly regular pattern, I start to switch off the things that mean least to me, one by one, day by day until after a numbers of days I find the balance that I can live with.
Personally I start with turning into perm 2G mode as I have wi-fi almost everywhere I go and I live in an area where 2G and 3G is on the cusp. This is extremely draining to batteries (I deal with none phone GSM equipment every day where battery life is key) and I know signal stregnth on the band you're using, constantly cylcing between band (and the variance in antenna power) is the single biggest thing to affect battery life asside from screen. It may not reflect this in stats, but trust me on this... If I lived and worked in a strong signal area, it would drop a few places down the list, extra call quality is nice as well as data.
For those of you living and working in London for example, but mostly out and away from Wi-fi, then consider leaving 3G on, and turning Wi-fi off.
Wi-fi scanning for networks constantly is another big drain.I have noticed this about Android, it allows you background apps to work leaner than the iPhone in power consumption when you have lots of widgets and synch etc. However the iPhone actually uses GSM to perform background tasks when the phone is off (shutting down wi-fi radio which reconnects as soon as you unlock the screen). This means that if you're out and away from a friendly hotspot all day, battery is less affected than an android.
Anyway, sorry for the long post, but hope you all have luck in finding your 'sweet spot' in usage / customisation.

hi guys i've been having a problem that i cant get fixed. ive asked some people and they are not sure what the problem, and also looked in threads and the fixes dont seem to work either.
i flashed the chadogr rom a while ago from cyanogen mod 7 becuz there were certain issues i was having with it.
when i had the chadogr sense rom, the battery would continuously die in barely no time at all, and when i looked at what was consuming my battery, "display" was always using at least 80-90%, and the phone would be dead in about 3 hrs or so.
got sick of it, and went to an aosp based rom called gingerbread evo deck 1.2w. it was very good and light on resources and battery life was good WHEN I DIDNT USE THE PHONE. but as soon as i started using it battery would drop so fast, but that didnt bother me, cuz sometimes i didnt need to use it. but there were somethings that i just couldnt stand with asop.
1. GPS never worked, EVER!! (i tried all the fixes to no avail) it was always searching for satellite everytime i wanted to use navigation.
2. it had awful signal strength (even wifi), constant disconnects, and always giving me this info that im internationally roaming (wtf)
3. a couple of other things not really worth mentioning.
i said eff it and decided to go back to sense, and decided on the synergy rom after reading the thread to great reviews.
i like the rom but im back again with those "high display" use problems again.
what is causing this and how do i fix it. there was a "fix" in the synergy rom thread but it didnt work for me. it said to go to the spare parts app and uncheck the compatibility mode, i did that and im still having those display issues.
here are some pics for illustration purposes:
this is the chadogr rom (sense), and after only about an hr, its down to 65% and look at what the biggest user is

sorry this is so long, pls dont bite my head off or yell at me , i dont know what else to do,
i dont have automatic brightness, screen timeout is set at 30s
im lost
pls help, and thanks alot guys
It's more probably a difference of the battery stats plotting rather than the drainage of the display. Display drains the battery most out of all the components in the phone, so that reading must be pretty accurate. If you're battery is draining ridiculously more over AOSP, which Sense ROMs usually do, than you might have a problem with the ROM or kernel themselves and not necessarily Sense, or it could be a more accurate reading for the Displays battery use. I am running Synergy Nightly 7/16 and my battery life is relatively good to CM7.1 RC1. And yes display is at the top at 66% at about 1/4 the time on(Ex. 2 hrs run time since charge, 30 mins display on). Turn of auto brightness too.
Also remember that it is displaying percentage, so the display being higher is actually a good thing. Your display uses the most power of everything on the phone, or it should be, when it is using a higher percentage of the total power available, it means that everything else is using less. The only way to get the percentage of display use down is to either turn the brightness down, or leave the display off as much as possible.
Click on display and you'll get an accurate reading of how much you actually used the display.
Synergy is awesome though, I went from 86% down to 85% when I woke up this morning. 10 hours off the charger and I wasn't even fully charged when I took it off. This thing is amazing with battery.
I have the exact same issue as the OP. I'm posting from my phone right now so when I get home I'll post a more detailed reply with pics but this is NOT NORMAL display usage. I'm getting sick of people telling me and others with this issue that its "just a percentage of what's using the battery and its normal ". Its not normal because this never used to happen to me and the display never used that much battery before. My battery life is horrible compared to a rom that doesn't do it. At most I'll get ten hours from a full charge and I can visibly watch the percentage drop as I'm using the phone. Even when I haven't touched the phone and the screen being off, the display usage will still be at like 90%.
It didn't use to happen, it seemed to just appear out of no where, the first time being with mikfroyo 4.62. I tried downgrading but no luck. I can only comment on roms that I have tried but it also happens with mikg and synergy and a few other sense roms. Aosp does NOT have this issue as I've tried a few differently ones. Currently using CM 7.1 and I'm getting at least 20 hours with heavy use.
I have been trying to get to the bottom of this for a few weeks but it seems that I just keep getting run around in circles. Now that I've seen other people are having this issue too hopefully we can get this worked out with some help. Its keeping me from using my favorite rom, synergy. I like aosp but it just can't match the performance and functionality of sense, oh and looks hehe. Like I said I will post up some pics when I get home to provide more evidence

Have you checked your wake time on the ROM? Wake lock issues are a more likely culprit than the screen when it comes to bad battery life like you described. Go to menu/settings/about/battery and look at your Up Time and your Awake Time. If they seem close to identical (even though you know you've walked away from your phone for a while and had the screen off, etc.) then you have a problem.
The most likely solution is a PRI downgrade to 1.77. Check your ROM's forum to see whether or not a particular PRI is suggested or not.

Its not a simple wake lock issue. My up and awake time are very different, just like they should be. Its not pri either cause I've changed it multiple times with the same issue. How would that even affect display usage? Every pri problem had caused high cell standby or android system but not display. I just bought system panel and I am going to let it run a monitor for a while and see if it brings up any red flags (using synergy). This is something a little deeper than a simple wake lock or radio issue.

Yep, sounds like it. All I know is that many, many phones (including mine) on gingerbread roms show very high display percentages. However, the phone lasts just as long as normal. The going notion is that gingerbread handles app and service power so much better than Froyo did that the display percentage simply has to be higher. That's how percentages work, of course. However, if your phone is dying at a much faster rate than normal, then yes, something is wrong, but I wouldn't be surprised if it has nothing to do with your display. Not that I have any clue what it might be, just sayin'.
It does it regardless if its a froyo or gingerbread rom. First rom it popped up in was mikfroyo which is 2.2. But weirdly it didn't use to do it on that rom. I achieved my best battery life (30 hours moderate usage) on mikfroyo 4.62.

I have three different phones.
Hero (rooted with CM7) - high display usage
Epic (Unrooted stock 2.2) - high display usage
Evo (rooted various 2.3 rom) - high display usage
All have high display except when I run Deck 1.2.1.
On my Evo some rom such as Sprint lovers (stock after auto root v2.5) 3.70 gave me high Android system, but most if not all gingerbread rom with the exception of deck all show high display usage including miui.
This lead me to think that high display usage is quite normal IMHO, just thought I'd share.

How high though? Mine and the OP display usage stays from like 80-90%. I can understand if its a little higher than everything else but this is extremely high. And why would extremely huh display usage be normal even if i haven't touched the phone and the screen is off? Its not normal because it didn't used to happen on the SAME rom. Like i said i used to be able to get 30 hours with mikfroyo 4.62, then this display issue came up and i cant hardly get 10 hours from a charge.

It's more probably a difference of the battery stats plotting rather than the drainage of the display. Display drains the battery most out of all the components in the phone, so that reading must be pretty accurate. If you're battery is draining ridiculously more over AOSP, which Sense ROMs usually do, than you might have a problem with the ROM or kernel themselves and not necessarily Sense, or it could be a more accurate reading for the Displays battery use. I am running Synergy Nightly 7/16 and my battery life is relatively good to CM7.1 RC1. And yes display is at the top at 66% at about 1/4 the time on(Ex. 2 hrs run time since charge, 30 mins display on). Turn of auto brightness too.

when i 1st got my evo, display was never the biggest power consumer, it was either android system, phone idle or something else.
its hard to believe the reading is accurate, when i know i havent even woken up the phone that much, currently the biggest user of my phone at home is wifi, yet that shows only like 4% or so.
oh and yes auto brightness is off too as stated on the bottom of my original post

Click on display and you'll get an accurate reading of how much you actually used the display.
Synergy is awesome though, I went from 86% down to 85% when I woke up this morning. 10 hours off the charger and I wasn't even fully charged when I took it off. This thing is amazing with battery.

ehh its ok, sure beats the other sense rom i was using (chardogr)
but still not blown away by the battery life.
i swear battery life is gonna be on the top of my list when im upgrading to my next phone, i cant deal with this **** anymore

I have the exact same issue as the OP. I'm posting from my phone right now so when I get home I'll post a more detailed reply with pics but this is NOT NORMAL display usage. I'm getting sick of people telling me and others with this issue that its "just a percentage of what's using the battery and its normal ". Its not normal because this never used to happen to me and the display never used that much battery before. My battery life is horrible compared to a rom that doesn't do it. At most I'll get ten hours from a full charge and I can visibly watch the percentage drop as I'm using the phone. Even when I haven't touched the phone and the screen being off, the display usage will still be at like 90%.
It didn't use to happen, it seemed to just appear out of no where, the first time being with mikfroyo 4.62. I tried downgrading but no luck. I can only comment on roms that I have tried but it also happens with mikg and synergy and a few other sense roms. Aosp does NOT have this issue as I've tried a few differently ones. Currently using CM 7.1 and I'm getting at least 20 hours with heavy use.

finally someone who understands what im going through, ive done everything and still coming up short with it.
I've had the same problem as the OP, specifically with Sac's Kingdom... Loving Sense 3.0, but the battery drain was a little much. Feeling your pain.
I'm going to PM myn and aamikam with a link to this topic. I don't think we will be able to figure this out unless we get some rom developers involved. Hopefully they actually take the time to read my message haha

thanks for taking this up brother, 'preciate it.
props
I feel your pain bro. What got rid of my issue was i downloaded battery callibration app from the market. Charged to 100% and then used the app. My battery usage went from 5hrs to 16hrs yesterday. I'm loving it. Everyone give that try and trust me it works. Currently running synergy rc2.

One thing I noticed, in your pics your signal is very low, if your signal is low your phones gonna use alot of juice trying to maintain and/or look for a better signal.
Try checking in an area with a decent signal.
@OP...as long as your up time and awake times are diffrent Your phone is completly normal...1) when your using sense roms your continuously using your phone,so your display screen is on all the time. Hence the display so high. 2) when your using aosp roms..your taking long breaks from your phone..the flat lines on your graphs...your phone is sleeping,allowing more batt life..your in 20+ hrs of use..when your on sense your in 3-4 hrs of non stop use..it looks to me u enjoy sense more and can't put your phone down LOL..so the more u use your phone the higher your display % is going to be.

Our smartphones have the highest battery capacity a smartphone has ever had (not including Galaxy Note which isn't really a smartphone anyway).
Unfortunately, people get mixed results with the battery.
In this thread, post your battery life results and personal usage. It could help people see the potential our battery actually has and could also help stop battery woes.
It will also be interesting to see the results from different ROM's and different kernels.
Here's what you post:
- Display time
- That battery graph thingy
- Battery mA statistics (install this app).
Posting screenshots of the above would be MUCH more helpful than just saying, 'Oh, my phone lasts 2 days with heavy usage.' Heavy usage is variable for each individual, so being specific would be much better.
Please also post your personal configurations, ie. brightness at x%, 3G on, Wi-Fi on xminutes, 'Tasker' profiles etc.
Hopefully, if people participate, we will be able to identify how people get great battery life and how some people get really bad battery life. Then we could compare personal configurations and see what settings/apps/tweaks affect battery - in a positive or negative way.
This should also clean the forums of the daily 'bad battery life' thread's in the forums.
I will keep some posts reserved for the future, where there could be battery tips as well as the highest display time and the lowest mA statistics.
Good luck!
Reserved for future use.
Reserved another just in case.
Reserved this to increase my post count
This is just a suggestion for future reference. It would probably be best to keep stats/results/tips separated by either "CM-based" or "Blur-based" ROMs.
I haven't turned on BMW yet so I will update this post once I get results.

Good idea, I'll do that once this thread starts to develop a bit.
Well my battery hasn't been normal ever since I flashed but
Rom-Neutrino 2.2 (GT-S ADDON)
Kernal-Faux123's 024 1.3ghz
Brightness-always at minimum
3g-most of the time when I'm not home
Tasker-you see that little green guy in the top left...
WiFi-its on all day when I'm home (no data plan)
Btw the link to the mA stats didn't work.

Battery life will vary by individual device hardware performance, individual battery performance, ROM, radio, kernel, apps installed and running/not running, how many times you reboot, how much data you use, wifi usage, bluetooth usage, etc., etc.
There is no way to compare everything which is a factor because there are too many factors. Every device is basically completely custom unless you take 2 or more completely identical stock devices and do some battery studies on those without changing anything. Even then you won't capture the differences in actual performance differences from hardware and battery performance which will vary across all the sample devices.
The best you are going to get is people just saying which ROM, radio, and kernel they use, and the up-time they get. In reality, this will be no different to any other battery life reporting done in many other threads. Comparing apples to oranges to pears. Better to just start a "who has the longest battery life" thread.
I believe this is more of an attempt for users to "compare notes", so to speak. It might help people understand why they are getting the battery life they are and maybe there might be people who can collaborate on which setups will meet their needs and obtain the type of battery life they want. At the very least, it could give users (with similar configurations) a place to see if they are actually experiencing any issues or if it is the norm with said configuration.
Also, this could be a step in consolidating a frequently discussed issue and in return reduce the number of new posts on the same subject.

I came from a Galaxy S (since in my country there are issues with Galaxy S2 signal), Atrix is really nice (this is my 2nd day on it), but about battery, the same rom but different kernel always do different results, last one on galaxy S gave me 2 days on battery with low to med use, but in Atrix world, in the few post I have read, I just noted that Atrix arent the same, looks like there are 3 versions of it (sorry if i am wrong, I am new into Atrix) ATT seems to be one and the 2 others tegrapart versions, do you think this also could make difference on the batt duration?

Yes every phone is different, but the battery's are exactly the same...
The fact that the hardware is a tiny bit different on each device will make negligible difference on battery life.
What will make the difference are personal preferences. This is why I'm requesting people to post their own one so that we could all get tips on how to decrease battery drain.
Anyways, let's kickstart things off. Here's mine - I'm losing 1%/hour on idle, with 3G on, brightness on auto and autosync on.
I only downloaded BMW yesterday, so I don't really know how it works. But something I noticed was that the mA keeps decreasing. Why?
And another thing, is the screenshot attached what you would refer to as 'good battery life?' I'm not complaining, but I'd like to see what mA people are normally getting while idling as well.
EDIT: Oh, and just in case... I'm running (custom) Neutrino GT ROM with Faux123's 024 1.3Ghz kernel.
I'm a new user to Motorola Atrix, only got it for a week. The first two charges were good (still had the stock rom-no root yet) afterwards I installed neutrino 2.2 and battery doesn't last long. My previous HTC Desire lasted idling for 14 hours and more at the same settings: HSDPA only with data, bluetooth on paired with bt headset and several apps with push notifications.
These are today's results:
Seems hopeless!
i flashed a cm7 image. i had a battery issue. i drained it, plugged it in, charged it to 100% per batterycalibration, and have had excellent battery life.

same here, under regular conditions (normal phone use, a few phone calls, a ton of texts and probably about 5 hours a day of streaming audio) i'm usually around 30% when i go to bed each night, that's 16 hours on battery
this is on cm7.2 kang (most recent version)
my battery life was pretty terrible until i did the trick above

This is the 'bluesleep' bug in my ROM.
It will be fixed in the next update.
For now, move the files in the attached .zip to /system/xbin and set permission to 777. It will considerably improve your battery life.
Using 2.2 WE from notorious, getting about 4hrs on average of screen time... Pretty aggressive uv as well as uc to 912mhz.
A lot of Web browsing for a mmorpg, texting roughly 10-20 a day, around an hr of phone calls, sometimes less, screen is set to auto, 2gmail accounts updating via push and weather updating every 2 hrs.
I don't know what else to say except a little earlier in Neutrino's post someone said freezing via tibu the following apps (Bluetooth share, truepoint something or other, as well as sensor navigation and atrix settings) since doing the above, as well as my other personal settings and usages I'm looking at 5 to 6 hours screen time today... Here is a couple of screen shots of what I go to so far.
Also, using 77.36 radio and gps USA mod from notorious and the v6 script.

Thanks for the reply and the help, I did that and left it from 100% overnight and after ~5 hours i got 55% same consumption.. (after I moved and changed permissions, I rebooted)
I was getting horrible battery life (less than 10 hours of use) from the day I got my Atrix, purchased second hand. After installing watchdog lite, I found that the suspend process was continually draining my battery. I encountered this issue on every CM7 based or Blur based rom, and was not able to find any solutions.
After recently upgrading to Joker's ICS rom, this issue is gone, and now after 10 hours of use still have a 56% charge on the battery.
Not sure if anyone else is having issues with the 'suspend' bug, but joker's rom has been a Godsend, can actually use my phone for a whole day now.
Alright I got one for you guys.
I recently flashed Neutrino GT and had the battery show 96% as max. I preceded to recalibrate the battery and got it back to showing 100% again for a few charges. Now somehow its reverted back to maxing out at 96%. I haven't flashed anything since I recalibrated. Thoughts?
