2.3.4 eclipse 1.3 in my situation, so I don't understand what causes such ridiculous Phone Idle percentages, is it from ram being abused, an unreliable connection, android hating?
(everything else is commonly below 10%)
wifi is typically left disabled, and i keep it slightly underclocked
what else android, what else!
I swear...the phone never truly goes into sleep mode...it stays awake for large chunks of time doing god knows what...every other phones battery usage graph I have compared it to looks completely different and only has small tiny lines of awake time...mostly when screen on...my x2 shows huge chunks awake when the screen hasn't even been turned on and data disabled for over 4hrs...I don't understand it. Killing my battery
it's a kernel bug, reboot yer phone immediately after unplugging it, every time. or downgrade to froyo (i got my absolute best battery life from froyo

Me?
Yeah I have been doing that since that fix was posted...it helps with life and awake times but it is still horrific compared to other phones...whether I reboot from power menu..power of/on...or whatever....it needs to be fixed...I don't understand why it does this...im about to delete the things that allow it to communicate with moto databases lol...
compare the battery capacity of other phones, most other phones come with at LEAST an 1800mAH battery, this thing is 1500mAH if you're lucky, couple that with 2.3.4's reporting bug and you end up thinking you're going dead much faster than you actually are.
I spend over half my days hovering at 15% or lower according to the phone, but I've also realized that it lies, alot... like my ex.
what does that actually do? =o
like what if you reboot a couple hours after unplugging?
... Christ what was 2.3.4 for if they didn't even get some of this stuff cleaned up
it prevents the idle process from "running away" when you plug it in it essentially disables the idle process, when it goes to re-enable it, it never stops, it takes up CPU cycles and burns the battery down for no reason and it will do it from the moment you unplug your charger/USB cable until you restart the phone.
why? beats me.
I thought you no longer needed to reboot after unplugging on 2.3.4? I did it every morning on 2.3.3, but stopped after updating to .4
I'm confused with this. Wouldn't a phone idle of 70% mean you the phone has been sitting there not being used?
As far as sleep, i use a cpu monitoring app from time to time and it shows my phone in "deep sleep" for multiple hrs when I'm not using the phone; my phone idle will show an equal high %, too.

that list indicates power consumption. if I reboot my phone in the morning, idle stays around 10-15%, if I don't, that number skyrockets 40-45% and by 5 or 6 pm, I'm hunting for a place to plug in.
my biggest boosts in battery life came from turning on "data saver" disabling "background data", anytime you can make the 3g radio shut off, you're saving TONS of power
I also just upgraded to a BH6X battery, it was the ONLY way I could make it through a full day when I was working in Cheyenne, Wyoming (cell service there, not so great) I also use wifi as much as possible 'cause it seems to draw less current.
battery life and signal strength definitely have a correlation. the less signal you have the quicker that battery dies.
also, "SuperDim" (available on the market) is a HUGE battery saver, not to mention the fact that the automatic light sensor just doesn't make the screen dim enough, ever. I kinda miss the semi transreflective screen in my G1, I never had to crank the brightness way up to see that one in broad daylight, made the colors funny but at least it was legible. but that's the price you pay for pixel density
I've never had bad enough battery life to try Juice Defender but my roommate uses it on his bionic and it does pretty well. His only complaint is having to load facebook or his browser twice to get data to come back on.

I am getting amazing battery life! Coming from a myTouch4G which would last maybe half of the day, its amazing!
I was at 51% when I plugged in my phone today. I have been using it all day and pretty extensively.
No juice defender either...
This is a mysterious problem for me also. I could have phone booted
up full charge everything that load's up is started. I could turn on airplane mode not do anything else for the day. (So No data no phones) And every-time I bring up screen I will see the amount of apps running go's up (ghost apps)
battery down & less & less ram available.
Has anyone ever tried to go into Sleep Mode I click it just locks up.
What's This Phone Doing Behind My Back??

If you manually tell your phone to go to sleep, you have to long-press the power button for like 6 seconds to wake it back up.
This bug happens on multiple Motorola phones (bionic and d3). I know for a fact that this has been brought up multiple times to Motorola thru customer complaints, Motorola feedback program and carrier complaints. But for some reason they don't care or feel its a big issue. For issues like this, I wish they would unlock the bootloader.
I just installed this:
http://forum.xda-developers.com/showthread.php?t=1246822
Have just been running it for a little bit but what I can see is that it definitely has an impact on battery life (in the good way). My battery seems to be dropping slower.
Thanks to 0vermind two posts above me.
how is the BH6X battery for you?
how long does it kick for? =)

I cant for the life of me remember but I read somewhere that unchecking the "automatic" setting in "date & time settings" stopped that part from oversyncing and draining battery. I have had mine unchecked for a while and seems to help some. Might be worth a shot. oh I usually 19% +- 1-2% on my phone idle at pretty much all times

That was me in "phone awake" thread.
What it solved for me was the chunks of time phone is awake(when screen has been off) are extremely reduced compared to when the setting is checked.
Only thing is that once in a while(mainly after bootstrapper use or a battery pull) the date/time is messed up. Easily fixed by turning the setting on for 5-15 seconds til it fixes itself and I turn it back off
Ash,
Yea discovered that today when I put in new class 10 16gb sdcard. No worries easy fix like you said super find been using your discovery for a week know working great.
Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.
Sent from my GT-I9000 using xda premium
Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

Since you didn't seem to realize, I thought I'd tell you. This thread was 5 months old before you posted in it...

Hi Everyone,
I've noticed a few other posters have indicated that wifi makes up an unusually large amount of their Prime's battery drain. Personally I'm seeing anywhere between 60-90% of battery usage being attributed to Wifi. Do we know if there are any commonalities in these cases? I'm on a fully stock .21 build with a C3 series Prime, and my battery life has in general not been amazing (6-8 hours off-dock MAX). Anyone else seeing similar outcomes?
Yep, there are quite a few threads about this already
The wifi power consumption is absolute insane. With wifi off the battery last as advertised... but with bt or wifi..... well...
Wish there was a way to select how much power we want to assign to the wifi as i have seen in another phones.
Im having similar issues, on and off.
Recently, Ive been messing around with new roms and and kernels and found out tinkering here and there that when the tablet is put to sleep, its supposed to go into deep sleep, this being what makes the tab super battery efficient when its sleeping
A quick test to see if its going to deep sleep is to download Cpu Spy free from the market, start it, go to options (top right) reset timers to get a fresh reading, put tab to sleep for 10 -20 secs, then turn on, go back to Cpu Spy, options Refresh. You should have a listing for deep sleep, which will tell you that deep sleep is at least working.
Every now and again i would test this, found out that sometimes deep sleep would not initiate, normally its ok straight after reboot, but after ive been using the tab (mind you, not always), and test deep sleep, i find that the tab would stay on a low clock speed rather then deep sleep, well 'low' being a relative term, i mean at some points, the tab wouldnt go below 475mhz even when idle.
When idle, ideally, the tabs if not doing anything intensive in the background, SHOULD go to the lowest CPU state, 102mhz, i think there is something, either system related or app related, thats forcing our primes to run at higher clock speeds and in some cases its not letting our primes go into deep sleep
I think using cpu spy, is a good tool to figure out what that might be, restart your tab, before doing anything, establish that your tab can go to deep sleep while sleeping and uses the lower cpu speeds when idle, and then test it everynow and again, if the issues come back, and you see a connection between a certain app or certain setting you've been using let someone know, chances are, it could be our culprit, in this case the best way to fix something is to find out what needs fixing.
I have already checked forDeepSleep issues but I have none, my tablet sleeps like it should and when turned off use very little energy... but man once it starts transfering data the battery goes to hell hehe (Music streaming, WebSurfing. anything that uses internet).
The battery used by WiFi is more evident when using the Prime in Eco Mode with the light turned all the way down, 80-90% is from WiFi :/
Changing the Policy to disconnect while the screen turns off just does noting for me, since I like I said before, it only uses so much power when transfering any kind of data.

Thanks for the info.
Just to get our ducks in order, do you test with CPU Spy after you have messed around with the tab, without closing or shutting down anything?
Most of the time, mine works as it should when 102mhz and deep sleep is concerned, but on occasion after playing around with it, i find that deep sleep wont initiate and the lowest clock speed would be 475mhz 370mhz, its as if somethings hanging up the system, not allowing it to initiate lower more battery friendly settings
At the time i was using virtuous prime with motleys kernel with the script specific for virtuous prime, that combination was not allowing lower clock speeds at all regardless what i closed or even a reboot, im now in the process of reinstalling virtuous prime with stock kernel as vanilla as i can make it, as a base rom with all my apps ready, and it seems to be doing what its suppose to be doing, CPU wise.
Gonna get the rom just the way i like it and nand backup, before i reinstall motleys kernel again to see if it improves the battery with its under volt features, this time im gonna wipe davlak and cache see if that makes a difference
Im constantly using eco mode, so thanks for that observation, will definitely keep that in mind when im testing
Sent from my Transformer Prime TF201 using XDA
Yep, what I do almost every day is reset CPU Spy stats when disconnecting my tab from the power so I can have an accurate read of the whole day.
Deep sleep working, CPU scales down to 102MHz like it should.
WiFi is like a black hole of energy when transferring data hehe, wifi on with only chat client and my email and Widgets synced uses almost no power... downloading anything, web browsing, music streaming eats the battery
My tablet also seems to go into deep sleep just fine (at least a few small tests indicate that it does). I'm having the same results as Zephyrot though, if I'm doing something that uses the data connection much it just hammers the battery. It's odd that I can play GTA III with settings turned all the way up for 3 hours and have it use less power than lightly browsing the web for an hour. Do you guys have C3 or C2 models ? I'm curious if the changes they made might have some influence on this problem.

For reference im on C2, but im in the phase of testing some roms and kernels(recently unlocked to try Cornerstone Rom) so my testing results are gonna be all over the place until i find the best performance/battery rom and kernel, untill then im gonna be doing basic short term tests, untill i settle down, so as far as my personal findings are concerned, take em with a grain of salt

Exactly my experience, Asphalt 6HD uses less battery than wifi!
C20 Prime here.
Since .21 update my battery life is crap! I can have fully charged tablet and dock, leave it overnight and next morning dock is completely drained and tablet has lost 5-10%. I thought it was wifi issue at first, but have tried several times in airplane mode and still have same result. After reading this, I will try cpuspy and see if it is a deep sleep issue. I cannot tell you how much I regret "upgrading" to .21, which I did accidentally and lost root in the process. Man, I wish this device had a do-over button!
I've tried a bunch of different combinations but I have gone back to GB every time. I don't even care about features anymore I just want to get the most out of my battery life. If you are getting great battery life will you post your kernel, firmware, and ROM please? Please post if you are on Ext Batt or not.
Thanks
I have an extended battery and I think my battery life is really good. Primarily, I turn off most automatic syncing and keep my screen turned down as low as possible at all times. I use a widget called Brightness Level and I keep it at 13% most of the time. I also keep GPS, Bluetooth, and WiFi off unless I specifically need them. Other than that, I'm not doing anything special. I'm on Clean ROM 4.5 Standard.
Sent from my ADR6425LVW using XDA
I think the biggest culprit is the screen. I'll get varying battery life every day, anywhere from 2 to 12 hours on a standard battery, or 4 to 30 hours on extended.
The only common factor in each of these for me is screen-on time. I'll get 1.5-2 hours on standard or 3.5-4.5 on the extended battery before it dies.
However, as previously mentioned, turning off Bluetooth, wifi, GPS, mobile data, and sync will always help battery life. Too bad I rely heavily on some form of data, email, and Bluetooth headsets for my work.

All in my sig.
I've got a system...
I usually can get through the day with a regular battery; a few things to remember:
1) Mail/messaging/anything push
if you can deal with it, set peak hours from like 7am to 7pm and get stuff every two hours during peak and every four hours during off-peak. Push means your phone is actively waiting or doing something almost all the time. This one single thing will make the biggest difference, except for...
2) The Display
The biggest energy hog of all. Actually not much you can do here but set it to time out quickly (a minute or less) and set to either auto brightness or remember to turn it down indoors.
3) Audio
Running audio through the speakers also uses more battery. Try headphones.
Bluetooth audio is great but again bluetooth also uses more energy than headphones.
4) Networking startup services
Lots of games install startup services that run constantly in the background checking for data from the mothership and/or other players. Get rid of them or turn them off if you can. Some apps also do this, I dont have a list but a little Googling will enlighten you.
Any other tips? I'm always looking for other (reasonable) ways to save battery.
PS: as you probably know, the phone (and any smartphone) will charge about %500 faster if its completely turned off. Common sense, I know, but you'd be surprised...
this will keep you going all day:

Seriously though, if you actually use your phone throughout the day, its probably better to just get the extended battery. Anytime you turn the screen on, it sucks battery.
You can try juice defender. I have it set to extreme and tell it which apps can turn on data with and without screen on, so 4g is only on when it needs to be.
I've heard ROM toolbox can keep apps from opening in the background but haven't paid for it yet. This would be good for games like draw something and WWF that seem to suck power constantly.
Thanks for the replies. I changed my power from performance to normal and that made a big difference because the phone won't sleep in performance mode. Just a note it will still sleep data even though my hotmail is on push. I am using the hotmail app not the htc mail app. I see people with 3+ hours of battery life in the battery thread and I don't see how they do it. I have the extended and I can make it through a day but I only use the screen for under an hour it seems. I'm not really seeing anything new in here I'm not doing but I do keep my screen auto a lot so I might jack that down. I keep every feature off when not in use.
I'm using stock rooted 3.14.605.5 with same firmware and over been getting better battery life since flashing.
I'm mad as hell about losing unlimited data!

Man, That's some serious ****
I generally get great battery life-around 4 hours screen on, 4g, gps. However, a few days ago I noticed higher than normal temps, and poor battery life.
So what changed?
I traced it to the installation of one free app. Picsart-uninstalled and everything is peachy again.
This is my second rezound, the first one always ran hot and drained the battery.
If you're having problems with heat and drain, run a full ruu and see if it helps, if not you may have a bad device or possibly a bad sim. I don't think that the device is the problem in most situations. More likely a runaway app, bad radio/firmware/build combo, user error, or expectations too high.
My setup:

Your issue may lay mostly in poor reception. I notice your signal strength thing is in yellow most of the time. Use WiFi if you can. I get pretty good battery life on
Ineffibilis GB
Feb OTA firmware. Don't remember the numbers.
Dsb 1.1.3 undervolted by about 100mv via incredicontrol (UV depends on the device, each is diff) and under clocked to 1188mhz and with interactive governor.
I think my power setting is on Normal.
Also I have weather sync every 3 hrs. Facebook every 4 and leave my Gmail accounts on sync.
I get between 3.5 and 5 hours every day of screen on time through out the day if I'm using my phone a lot. This would also be coupled with usually around 30 minutes of phone calls too. But usually I only charge it every other day (when it gets to around 30%). I get more time out of it on WiFi (5+ hrs and less on 4G (3.5 to 4 hrs at most throughout the day). I also never run my phone down to less than 20% if I can help it. I'm on stock battery too

That battery life isn't great if you're only using 9m of screen on time. 60% after 5 hours isn't unusual for me if I have medium usage of my phone. Like platinum mentioned, your signal is terrible. The Rezound (and most phones) tend to use a lot of battery if they're trying to constantly find a signal.
Right. Battery should only drop 1 to 2 percent per hour on good signal. Bad signal can kill it... If I was on 3G my phone would be around the mid 90s with the same usage.

Does it matter if I turn off data or it will still drain looking for cell signal?
As long as you don't have partial wake issues, there are only two real concerns for battery.
It's not processor. Again, if the phone's not 'awake' while the screen is off, your phone's processor is not ramping up to full speed at all. While it's on and in your hand, 1.5ghz is a great speed for it to operate. Slower speeds than that significantly slow down how your phone operates, and you will have your screen on for seconds longer (Which uses WAY more battery than the higher clock speed).
In Facebook app, go to menu > settings > and change the refresh interval to NEVER!!!
As of Android 2.2, Facebook does push notifications. You don't need Facebook refreshing very 4 hours (OR EVER!). This wakes up your phone (ramps up processor speed, and so on), uses data (battery), and is unnecessary (since you get push notifications anyway). Turn that crap off. Same with Twitter. Turn it down to manual refreshing only (look in settings > accounts and sync as well as in the app). Same with Friendstream (which will automatically have its own refresh settings - fix them).
There are two things that use your battery.
1 - Screen. Turn your screen off when you're not using it. Stop turning your screen on every 12 minutes to 'see if you have any notifications'. Trust the green LED blinking light, or listen for your phone. You can stop checking it. You're using a TON of battery lighting up that 4.3" screen AND waking the phone back up (ramping up the processor, among other things, and it will stay awake for at least minutes, even after the screen goes back off).
2 - Data. Turn wifi off if you're not using it. Turn Mobile Network (GASP!) off when you're not using it. Pull down your notifications and hit Quick Settings, and turn Mobile Network off. Don't have that? Make the HTC Widget > settings > Mobile network. Turn it off when you're out with your friends after midnight. a) you're not going to post anything reasonable or coherent when you're out drinking anyway to Facebook, and b) call and text still works, so you can still mack on honeys all night (and text them drunkenly). You don't need your damn Gmail at 1am. I know you don't. Don't try to convince me otherwise.
If you keep your screen time to a minimum (and brightness down if you're not using auto brightness), and TURN OFF mobile network (internet) when not using it, your battery will last DAYS. Yes, the stock battery. Now, do you do 100+ texts per day? Sorry, your battery is going to die today. And tomorrow. Every day. The screen time murders the battery, and the Wake time that your phone will have as a result (like every time the phone lights up - for minutes at a time, it'll stay 'awake').
That's how you keep your battery going. On any android phone. Yes, an extended battery works great. I bought one (half price in a verizon store) AND got an EXTRA one for $4 (on amazon.com). Yes, it's for thunderbolt, but YES it's the same part number. It's running my phone right now. Keep it charged, and in your glove compartment. Your life will be better.

Go get it. Turn off your internet, and your screen. Trust your LED notification light. Stop using MMS Screen On. Your battery will last all day, every day. Unless you text a lot. Then, good luck.

In short, yes.
If u turn off data it will help. But you will still have poor signal, so Idk how much it will help. apps and processes that use background data won't be using it, that alone will keep your phone from reconnecting so much, so it will help.
It takes your phone longer to connect on poor signals and your speeds are slower so it takes longer to do the same things. This also keeps your processor running faster for longer times.
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.

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?

Fantastic. Looks like you got your 10 posts That tip is about as useful as "don't plant cauliflowers in concrete".
