Hi everyone
So I recently got a S2, upgraded it from stock Gingerbread to stock ICS via Kies, then flashed CM9. CM9 was great, but I quickly noticed worse battery drain than that of GB. I sorted out all wakelocks, now facebook is the top one in better battery stats list and it's only 10mins in a day so I don't think that's a problem. When charging, vbus_present shows up and keeps the phone from sleeping, but that's a normal thing when the phone is plugged, right? CPUspy shows the phone is in deep sleep the majority of time I don't use it, so I assume I have no wakelock problem.
But even then, the battery still seems a bit bad. When in deep sleep with wifi and mobile data off, it would lose around 1.5% per hour; and with moderate/high use (internet with wifi or gaming), I'd be lucky to have it last 3 hours. Charging to 100% from zero takes about 3 hours.
I also tried recalibrating the battery through BC, but haven't noticed too much of a difference.
Recently I found a guide on disabling fast dormancy via the build.prop file. Still waiting for results though.
So, my questions
1, My battery usage seems normal, doesn't it? 1.5% per deep sleep hour is acceptable I guess, but 3 hours of usage seems a bit short. Too short.
2, What effects does fast dormancy have?
1) Totally unacceptable. Mine lasts at least 7-8 hours with high use..
Does your phone heat up while the heavy use ???
What brightness level do you use for the display ???
How many apps do you have that can gain internet access ???
2) By default, the Samsung Galaxy S II has Fast Dormancy support enabled. One of the goals of Fast Dormancy is to increase the battery life of a device, by limiting the amount of signaling between the phone and the cell network. But, when Fast Dormancy it is not enabled in the network and is enabled on the phone it ironically works the other way around, and actually drains more battery than before.
Luckily, Fast Dormancy can be disabled on the phone. For the Galaxy S II, do the following:
Dial *#9900#
Press “Disable Fast Dormancy“
Press “Exit“.
Easy as that!
Thanks for the suggestion I have brightness manual and at around 20%. Wifi is disabled when not used, and mobile data is always turned off unless I need it, so basically apps only get internet access when I want them to. I have also disabled sync for both google and facebook, but fb still pushes notifications to me while it's connected. Is that a major battery drain, and if yes, how to disable it?
Anyways, facebook, instagram, youtube are the only apps than can access the internet. No messengers or anything that may keep a wakelock.
My phone doesn't heat up during normal use, maybe a bit when I do some gaming (Max Payne?)
Also, *#9900# doesn't do anything on my phone. It doesn't bring up a menu or anything like that.
Bump. Guys?

Install BetterBatteryStats (search for it on here/Google Play), might help you nail what's causing the drain.
Yes I did, as said in my original post. After a night the highest wakelock are just around 10 minutes, and that one was facebook. Uninstalling it however had no effect.

Thinking logically, there's got to be something else in those stats (partial wakelocks in particular) that's causing that drain. There's no way having fast dormancy enabled/disabled is either going to cause/fix the drain you've mentioned getting '3 hours of usage'; (I can get 5 & a bit hours screen on with CM9 & variable usage/mostly 'moderate' use) given everything else you say you've tried.
Post BBS logs here if you want someone to have a look.
Edit to add - Also post a screenshot of the 2nd screen in settings/battery, the one that has history 'details' at the top, with the 'mobile network signal' bar underneath the main battery graph.
Here you go: pastebin.com/1UwicChJ
I just registered half a day ago and don't have enough posts yet to paste links, so sorry the phone was only on battery for nearly 2 hours with some light browsing and facebook, but I hope it works.
Anyway, I looked through my running processes, and dsp manager is the only non-OS process running, besides facebook. I got CM9 so it came by default. Could dspmanager be the culprit?

It's a new phone he's got there and I doubt it could be anything battery related itself.
I'm using CM9 nightlies and I get around 9 hours moderate use. It has been said though that a lot of these CM9 builds have battery drain and heat issues.
I use Juicedefender to help with the battery life which seems to work.

About 1/3 of this time was on wifi browsing. The drop is much more drastic if I play games.

A couple of observations. There's nothing that stands right out in the BBS log. The other one is, looking at that graph you've lost ~15% over a bit under 2 hrs. The screen has been on most of the time the phone has been awake (confirmed by the BBS log) if you look at the respective bars. You've also been using WiFi for most of the time the screen has been on/phone has been awake.
Roughly speaking, going by the screenshot, you'd get ~5hrs+/- screen on time if you kept using the phone in the same way you had during that just under 2 hrs, and this is pretty much normal. I haven't had drain issues for ages, so I double checked my details on the 2nd screen of settings/battery to make sure CM9 is reporting these details accurately (screenshot attached). Certainly in my case, this screenshot reflects what my phone had been doing for the just under 5 hrs it had been off charge/since last reboot; that is, >90% of the time in idle/deep sleep. So it probably isn't CM9 reporting these details inaccurately in your case either.
The BBS log & screenshot don't illustrate the problem you talked about in your OP. Now, if I had to take a stab in the dark at what's causing problems when you do have them (and FWIW, I do believe you're having the problems you mentioned in your OP at times), in the absence of any other info, maybe your WiFi router is constantly sending the phone packets (what's been referred to as a 'dirty router' on here before) when you're connected to WiFi & not actually using it. This scenario has been known to cause relatively high levels of drain.
So to be honest with you, based on that screenshot & the BBS log, I'm not really seeing a problem.
Now, if you want to post the same again when you actually have a problem with drain similar to what you described in your OP, happy to have a look at them. But for that ~2hrs covered by the BBS log & screenshot you posted, that's pretty much normal.

Okay, much appreciated so I guess I'll take it from your reply that 5 hours with wifi browsing isn't too bad. Seems okay, but I still find it a bit strange that (in my case) wifi browsing uses just as much battery as games do. I always thought it was a light activity!
Or maybe it wasn't the battery that had a problem, but that I set my expectations a bit too high. I came to this S2 from a BlackBerry 9700, whose battery would last half a week with very frequent use. But anyway, I just got this phone for a week, so I consider myself a pretty heavy user. Probably when I get familiar with it, I won't feel the need to play with it every five minutes and battery will last a bit longer then! xD
Nah. Anything with screen on is far from 'light activity'. Screen consumes far & away the most juice. In saying that, I've seen some people on here say they can get 8-9 hrs screen on with 2000mAh battery. How they do it I have absolutely no idea.
But if yeah, 5 hrs with the screen on most of the time whether browsing or playing games (games in particular are very CPU/GPU intensive & thus use a lot of zzzzs; unless they're really basic games like chess or similar), or anything else isn't too bad. Can you do better ? Obviously, if people say they can get 8-9 hrs. But it's not a matter of doing A, B & C and you'll magically end up with massive screen on times. Every phone is setup & used differently, and getting the absolute max out of every charge takes a lot of trial & error and experimenting with settings/setup.
There are tons of threads about the subject on here if you feel like going down that path. For me, I'm happy with the battery life I get these days because you can really obsess over it & spend a lot of time stressing over it/trying to maximise it for often very little gain. I'd rather simply use my phone a lot during the day & charge it at night.
Yeah Crackberries are like Japanese cars, they can run on fumes pretty much ;-) Having a dual core processor, a decent GPU & a huge screen kinda changes things.
There is one thing you can do fairly easily tho. And that's to make sure the phone spends as much time as possible in deep sleep when you're not using it. That will ensure that you have enough juice to get you by when you do want to use it. Simple ways to help achieve that is to turn off data/WiFi completely when you're not using it (tho many people don't like to do this for different reasons; which is perfectly OK if you're happy to live with the resultant drain), and make sure you've got no apps that are doing things they shouldn't be doing (like syncing, for example) while the phone should be sleeping. Again, there are lots of threads about same if you ever feel like a bit of light reading ;-)
So yeah, if you do find you experience drain that's not normal/outside the usual pattern you have, definitely post details & people can have a look for you. And as you said, you'll get to know what really is normal with regard to drain & so on is as you use the phone more (I tended to use it constantly for that first couple of weeks as well).

Already took such measures. Wakelocks killed my battery over my first night with the phone, and I woke up after 7 hours to find a ~50% battery completely empty. Now things are alright, I clear CPUSpy stats before I sleep and wake up to around 95% of deep sleep time. Overnight drain varies between 5 and 10%.
And yes, yes you are right. Maybe I should stop going nuts. I'm checking BBS and CPUSpy every hour, reading every XDA thread on battery, and calculating my battery drainage every morning I wake up :laugh::laugh::laugh:

Umm...so I just woke up, and noticed a wakelock in the kernel category. It was PowerManagerService, and it occupied around half an hour. Overnight, aftet I've slept 10 hours (got a day off ), my battery came from 24% down to 13%. That's a rate of roughly 1% per hour. Is that normal? And also, what is that PowetManagerService wakelock?

Because Im seriously curious... This phone has a rap of being "atrocious" in terms of battery life... Now I'm not making this post to be mean or anything, In fact I really do want to know what IS causing it or some theories.. and share one theory I have
But my personal experience really says otherwise, Tonight I set a new "record" on my One X+, 16 hours 28 minutes with 2 hours 43 minutes screen on time... And I didnt do anything "extreme" to achieve it, My Google Now is on, my location services are on, autosync is enabled.. About the only thing I have done is install JuiceDefender (My previous record without Juice Defender was about 15-something hours) I watched youtube videos, Read some websites, listened to music, and even played some games... I'm completely stock, no roms or anything
Now, I will note, I had a problem the other day where my battery killed itself, FAST.. After a bit of digging around and tweaking, I discovered the cause was that my One X+ wasnt entering Deep Sleep, and thus the processor was staying at 475mhz or so even when the screen was locked (Causing the battery to be drained like i was using it) What caused this? My Wi-Fi, of all things, While I had a really good signal, I had it prioritizing the 5.8ghz radio, and in my room, the 5.8ghz signal is fairly weak as im a ways from my router... so the phone was switching between it and the 2.4ghz signal, causing the phone to be unable to sleep, Removing the 5.8ghz AP from my phone fixed the issue completely and my phone returned to "normal" behavior...
Yeah i know it sounds really farfetched and weird, and took me a bit of googling to get the idea that this might be what was causing my issue (I tested my hypothesis by turning Wi-Fi off completely and using Cell data, Sure enough my phone slept like a baby and barely used any battery.. i flipped Wi-Fi on and suddenly the phone was drinking its battery down rapidly.. I disabled the 5.8ghz AP and suddenly the phone worked 100% properly again)
I suspect that this is the cause behind some folks who are saying their phone is draining down 7% in 20 minutes with it locked, Its simply not entering deep sleep, the processor is doing something in the background... Could some of them be having the problem i just described? Its possible, Especially if you have multiple Wi-Fi points in your house.. Could the wi-fi in the One X+ be bugged? I dunno, Thats possible to, Thats why I'm posting this...
Now of course some people need a phone that is going to go for 2-3 days without a charge, and no, this isnt the phone for you (There arent many smartphones out there that can manage that if you actually USE it any) But really.. 16 hours with 3 hours of screen on time is pretty darn good.. Thats getting quite close to my Galaxy Nexus with a 3500mah Extended Battery (Around 18h standby, 3.5-4 hours screen on) despite all of the "handicaps" the One X+ has over the simple GNex (Like LTE and a Quad Core processor) and is vastly better than my stock Galaxy Nexus battery which died constantly...
And yes, heres a screenshot as proof if you dont believe me...
I just want to add that I find that googlenow also drains the battery and as such I always disable it. It was a problem on my S2 and thus I have disabled it on my HOX+
Honestly, mine wasn't lasting longer than 8 hours until I rooted it and simply "froze" all of the AT&T apps I wasn't using. That alone gave me an extra 2-3 hours a day of battery life! (I've read here that the AT&T apps, even if you aren't using them, keep running in the background) The other thing that seems to help is an app called Smart WiFi toggler that's done wonders for both myself and everyone else I know who uses it in terms of minimizing WiFi battery usage.

I'm sure other folks have other tips, but this has been the winning combo for me.
I should add that i also froze every ATT app i could and never opened ANY of them.. So maybe thats part of it as well..
JuiceDefender i believe is doing something similar for me with the Wi-Fi by turning it off when its not needed...
My battery life was terrible when I first got this phone. I let it charge out completely once this month and I've been using LBE Security Master. Those two things have greatly extended my battery so much I have been able to go more than a day with it before charging. Another factor might be that my phone isn't carrier branded or anything.
The "My Wi-Fi isnt letting my phone enter deep sleep" thing is actually starting to get annoying, I thought i fixed it but it keeps coming back...and yes, it is legitimately killing my battery at twice the normal rate because the phone will -not- enter deep sleep
My phone goes into deep sleep just fine if i turn Wi-Fi off...and my battery drain returns to normal....So it cant be some app downloading stuff or constantly pinging the internet or else it would do the same thing when im on LTE...
Also i've reset the "Keep Wi-Fi on during sleep" option to never 20 times now, it keeps going back to "always" on me...
Ideas?
My battery life is ok. See here:
http://forum.xda-developers.com/showthread.php?t=2067143
Mine is too, Provided i turn Wi-Fi off or i get the bug to go away for a bit (basically toggling wi-fi on and off a few times and twiddling with the settings makes it work right, but the problem comes back minutes or hours later)
Otherwise, Wi-Fi wont let my phone enter deep sleep, and my battery drains like im using it..
The thing thats annoying me more is that the "Keep Wi-Fi on during sleep" setting will not stay where i set it and keeps going back to the default setting....
I guess i can just toggle wi-fi on and off manually...
what are others thoughts on some of the pros and cons of this update? i'm thinking it will actually save battery to have wifi 'always on' in standby mode rather than repeatedly switching between a on/off state which uses more energy.
It will definitely eat more battery if it's always on under the lockscreen...
Also there is an option to deactivate notifications when new wifi hotspots are around.. if you are about battery life you should deactivate this..

I keep my Wifi always on because it consumes the least battery (vs 3G, LTE, etc).
If I don't play games on my Lumia 920 the battery can last 3 days.
This update is freezing my phone Dunno why but I have tested it. I occasionally get a freeze now and then, but when the keep wifi is on, it is like every couple of hrs... Will test it more though.

Wrong unless your phone is using 5-year old wifi chip.
Correct me if I am wrong, but is the wifi on this phone an on demand type system? From what I see on mine, the wifi unless being used for an actual update or downloading other content goes to sleep when the lock screen is on. It then wakes up if there is an update pushed to it or if something else needs it or of course if you unlock the phone. At least that is the way it appears that mine works.
Also your radio service are going to use much more power than the wifi will as they are higher power transmitters and receivers. There is a reason wifi only works within a few hundred feet and radio works for several miles that is due to the power difference. Of course with more power you get more battery consumption.
In the case of conserving the battery you are better off to use wifi when possible, leave it on and let the phone control it.
In my experience keeping Wifi on permanently lead to a remarkable decrease in battery life. That will depend on where you are though. If I have it sitting at home where it has Wifi connectivity it's likely that I would see better battery life because all actual transfers will happen via Wifi. At work though it can't connect to the Wifi network (private phone, work network) and so I have 3G running anyway while the phone keeps looking for Wifi networks to connect to.
The problem boils down to the fact that while you can switch off Wifi completely because everything can still work using 3G you can't switch off the phone part completely because only data is done over Wifi but you still need the mobile connection to receive calls/SMS.
I would suggest to anyone to simply try out what works better for them. For me it worked best to let Wifi deactivate automatically as it had been the default in WP since WP7 came out.

Maybe Wifi is using less power when you are downloading something and need a lot of data... But when your phone is idle... Constant on Wifi is using far more battery power than 3G that checks for email or weather every 1-2 hours...
Simple enough...if you are consistently in an area with a WiFi signal, leave WiFi "always on"...it will consume less battery. If you're in an area without WiFi signal then turn it off, as searching for a signal will help run your battery down.

Again, simply not true unless you are using a 5-year old phone. Even if you are in an area that has no wifi connection, the extra drain caused by searching for Wi-Fi networks is minimum in a modern OS and modern chipset. I have left all my android phones (the ones that offer Wi-Fi always on feature for a few years now) wifi on all the time. Never have felt much difference vs if I turn wifi off. It annoys me that WP didn't offer this capability for so long.

I tested a lot of phones Android and WP, my experience is that wifi always on is a battery killer... And I'm talking about state of the art hardware... It's just my 2 cent's but i keep it off...
When I don't charge overnight and wifi is always on my battery drops about 40%
with only 3G on about 8-10%
Foxbat: you can leave it any way you want to do it. I'm not saying Microsoft should remove the feature. But in my experience keeping Wifi on kills the battery faster. I tested it for my use case with always on and with Auto and in the end: Auto it was for me.
The best advice you can give to people is: try it out yourself and you will see what works best for you.
A picture or two says it all. See the attached files for my two testing: one with wifi always on for 24-hour and one with Wi-Fi in auto mode for 24-hour:
The right picture shows 0.0%/hour under current discharge rate... pretty impressive

The keyword is 'Current' -- means at that moment. You can derive the same thing from the left in various sections. The key here is that I don't see any discernible difference. Certainly not a battery killer in any sense as you claimed.
If you look at the first 12-hour period of both chart (when the phone is mostly sleep and not used), the result is almost identical. FYI, there are three push emails connected all the time: Hotmail, GMail and Corporate Exchange Email.
Yes the keyword 'Current' -- means at that moment... so your phone is not discharging although your screen is on... Very accurate app...

So, what you saying is that if you have the screen on, you will see your battery percentage drop immediately? You should return your phone if that is the case.
Battery app get its information from the phone OS reporting. If the OS reported the same battery percentage over a short period of time, the discharge rate won't be anything other than zero. That's limitation of the platform, not app.
Instead of criticize the app which is not the point of the post, why don't you post your findings where leave Wi-Fi always on kills your battery?
it' % per hour... and your phone is using currently using 0,0% per hour so if you leave it like that it will run for ever... so where is the mistake?

% per hour is a unit of measurement. It doesn't mean you have to take one hour to measure it in order to claim its rate. That will be average rate on that hour, not current rate which is meant to see what your current usage pattern is. It can't be used to predict your battery life. If you notice that when you take your phone off the charger, it will stay on 100% for quite some time before it starts to drop. Does that mean your phone battery can last forever? Think about it before post these ridiculous statements.
Foxbat - you are trying to tell us how our devices should behave while we are telling you how they actually behave in the real world out there. You can repeat your 5 years story as often as you want to but it clearly doesn't live up to the factual reality we experience every day and I guess after trying it out with different ROMs on the 920 and leaving all other settings the same I know the effect it had pretty well.
Nice to know though that you are having a different experience with different devices.
Anyone else having issues with battery life? I can go from 54% to 14% overnight, totally stock install with no added apps.
My HDX 8.9 only loses about 2% over night. Get a task killer and see what you can kill.
Fully recharged it, watched a movie for a few mins, then let it sit for four hours or so. It managed to go from 84% to 72%. For some reason while it does stay connected to my wifi, it keeps losing internet connectivity.
I got a taskkiller app and killed a few processes, I don't believe it should be necessary though. I wonder if I got a dud since no one else seems to be reporting the same issue.

Totally stock install, to my knowledge I can't uninstall any of the preinstalled stuff. The battery issues persist though reboot so if it's a stock app with some issue there's not much I can do about it at this time.
On a possibly related note I've been having issues with internet connectivity, after my fire is inactive for some period of time it loses connection to the internet but stays connected to wifi. I have to toggle the wifi to get the data working again.
I finally decided to just get them to ship me a replacement, should hopefully solve all of my issues without me having to spend days trying to diagnose any problems with my limited access.

I have discovered that the location services can cause this exact issue due to constant polling. This issue is worsened with the additional use of the Google Android location services. Make sure you do not have the Location setting turned on in the "Wireless" tab of settings.
This issue only occurs intermittently, but when it does, it continues until location services are disabled & the device is restarted.

It wasn't enabled, I got my new kindle today though and just unboxed it. Hopefully it's resolved now.
Edit: Nope, same issue. When I got it, I turned it on, went though the tutorial, made sure location wasn't on, then turned off the screen and sat it on my desk. Six hours later I'm down 16%. Guess it's not as bad as before, but it's still not great. I wish amazon had better battery stats.

Edit: Nope, same issue. When I got it, I turned it on, went though the tutorial, made sure location wasn't on, then turned off the screen and sat it on my desk. Six hours later I'm down 16%. Guess it's not as bad as before, but it's still not great. I wish amazon had better battery stats.

I have great battery life and idle time. Did you download anything at all? Did you change any settings?

Nope nothing, I can't think of any reason why two separate devices would act this way when no one else is having the same issue.
From when I edited my previous post to now, it's gone down 33%. (Which is a little over 2% per hour)
Edit: I installed better battery stats from an APK (didn't realize it would let me do this), so hopefully now I can see what's eating up the battery.
Edit 2: Something called msm_hsic_host is what's draining my battery. Apparently that has something to do with a cellular modem, which I find odd since my device is wifi only.
Edit 3: Installed DS Battery Saver, set it to slumber (If screen's off, data's off), problem solved.
I mean.. there is some serious hardware inside, but software is literally an unlimited stream of crap. So many obvious and infuriating bugs and they don't even fix them. Is it even worth using this phone anymore?
I'd love to see an 8.1 update but I'm curious about what's biting your phone. I see nothing to complain about on the ones I and my son received last week. There's no new build on them but battery, wifi, video sync, call quality, even the camera focus problem most people reported don't seem to be an issue.
I was careful to remove the adups spyware on the first day, and added Greenify, noLED, Life360 and the latest action launcher. I also limited background apps to 3, and turned off as much location tracking stuff as possible in Google Maps without completely neutering it.
I get about 6 hours of SOT, and despite life360 the standby drain is negligible - if I set out to conserve battery I can get 2 days easy. The only downside I can find to this phone is that the decacore eats battery when playing Monument Valley 2.
But maybe it's just that my usage patterns are different. Can you describe some of the things that your phone does that bother you so I can try them on mine? And did you already get rid of the adups junk?

I have not removed the junk that a comes with the phone. Did you root to do this?
I am not having the issued described here in XDA as well.
I am getting roughly a day with my battery.
In my experience, it is the screen that is eating up my battery.
When Auto brightness is on, it gets too bright for me so I setup a custom auto brightness using tasker.
No need to root to remove spyware, just install ADB on your computer and then do per https://forum.xda-developers.com/elephone-s8/how-to/beware-com-adups-fota-myapplication-t3741622
