I figured I'd make this its own thread after speaking with several people with the same problems using a CMOD 5.0.5.3+ rom. This wasn't a problem in lower editions from what I can remember in testing.
Idk but I believe it is something in the kernel affecting this problem with the display hogging my battery. Even after flashing an undervolted kernel I still can only last 24 hours with an extended life battery, vs a weeks time before. And the display problem has been like this in all CMODS test .6 Roms as well so idk if it is in the process of getting fixed or simply overlooked. And other Rome work well but are slower it seams.
The display settings doesn't matter auto or manual its about the same. So devs what can we do to find the change or what can I do to help?

I'm running test 3 of 5.0.6. Today i read a book with fbreader for around 2hrs on it whilst on the train, had 2 30 minute phone conversations, around 20 texts, a dozen gtalk messages, and played blackjack for about 20 mins. i'm also using pershoots OCUV kernal, and after 11hrs without being plugged in I am at 75% battery. I'm happy with that.
I think it is a work in progress, as each new build comes out it's better. His testing builds are just that - testing. None of his release builds I have ever had an issue with either, although maybe my phone ue is a lot less than others I dunno. All i can say is i've never been tempted with another rom since early days on my magic phone Cyanogen rocks!

Nope, I have it on auto-detect, so quite bright when on the train and outdoors. I have setCPU (market, paid) running and set battery profiles - although I haven't hit them yet. I have it set to max 1.1ghz 100% to 50%, 998mhz from 50% to 40%, 776mhz from 40% to 30%, and under 30% to 500 and something.
I do use an app called autostarts (market, paid) and have set everything but system services/apps to not run on any kind of state change or startup. I use Advanced Task Killer to kill apps as soon as I finish with them.
But i've had all these for ages, I just think a big improvement on the last release test 3
Nandroid your existing and try out test3.
I've been experiencing the same symptoms with my battery usage generally dominated by the display. I'm using a UV kernel currently (intersectravens) so we will see if the same happens.
KingKlicks's DESIRE rom doesnt have the same problem it seems and the battery usage is much better.
Wondering if there is a underlying issue.
after .6 test 3 the battery has improved decently, still the display is hogging battery life more so than in the sense rom
Same thing here... Display totally kills the battery with CM5.0.5.3 and OC/UV kernel. Phone rarely lasts over a day with moderate to low usage...
Without usage I can barely get a days use :s
I get the impression that its not the display. I can have 50% display usage, sleep my phone while playing a MP3 and then have more than 50% usage... suggesting that its either he display+something in one category , or there is a bug.
The stock ROM always showed display at the highest usage also. I'm not saying that there isn't an issue, but remember that those numbers are all relative.
I'll say this: I charge nightly to prevent my battery "deep cycling"....That being said I un-plug at 8am and plug-in at about 11p-12a, I use my phone a TON.....usually when I plug in I have about 45-55%.....Not bad at all.....
I originally thought display being the main battery hog was a bad thing.....Then I thought about it a bit......
Would you rather the "system" use more batt? Cell Stand by?
Display (by all rights) should use most battery. More usage=Less time with a fully charged battery.....
Im using CM 5.0.5.3 and I switched Roms after using the stock for 3 months. As soon as I moved to CM I immediatly noticed the battery life was lower than before. I hope you find an issue to this problem ASAP.......I love your ROMs CM, but I love my battery life even more
Good luck with this !!
"display" = gpu acceleration and actual amoled power
Something else i just noticed, very odd. I had 41% display and 23% spotify.... i had been playing for music for a while (offline only). When i quit the spotify app... the entry from the battery usage vanished and display took a spike to 65% ish... really odd. Almost display is showing usage for a group of things.
What? How ? I get 6 hours maybe 7 if I'm lucky out of my battery.... even b4 my nexus was rooted ... how r u guys gettin 24

Ignore any figures people quote - battery life is always relative. One persons 'usual' usage is different than yours. A friend of mine brings his N1 to works and it sits on his desk syncing email - he gets 1 full day.
I bring mine, sync 2 accounts, play a lot of podcasts, have a RSS syncer going and use twitter and FB loads, i get a LOT less.
Dont worry to much, your usage figures are pretty normal depending on your usage patterns.
They say your mileage may vary for a reason
Battery Life
My Battery life has always sucked. Maybe I should buy a new Battery?
If I take my phone off the charger at 7:30, and don't plug it in all day, then I will be at about 30% or less by the time I get home at around 5:30. Unless I don't use it. But I use my phone to play stream music pretty much all day. Or at least 4 hours. One day I forgot my USB cable and I was below 20% by 3:00.
It is still better than iSuck, I mean iPhone, and worse than a BlackBerry. I have electricity everywhere though, a car charger, and an extra battery is like 25$?
So what is the big deal? You have the equivalent of a desktop computer from like 2002 in your pocked running off of a batter the size of a credit card, how long do you really want the thing to last anyway?
I have been messing around with system tuner app for a while now and I really like the program.
I would like to hear from people who have used this app and their results with various tweaks that this app provides.
in the boot settings menu:
1. forcing both CPU's online: this should technically give you a better battery life, since it puts less strain on on cpu at a time, has anyone had a good exprience using this?
2. Boost app loading: anyone had any significant improvement with this?
My own settings:
I usually clock my phone at 1.5 (on demand governor) even though faux's kernel allows 1.7 max. I put max clock for screen off at 384 and conservative governor.
I have Undervolted before but do not see a very significant battery difference so I just left it alone.
I tried out the autokill option of system tuner, I only tried to kill the ghost apps, to refrain from the cpu from having to keep restarting the phone, but this also seems to kill battery life...In my experience any type of task killer however detailed will reduce battery and does not increase performance, unless you're running a poorly written app that just needs to be killed.
I use three other programs to monitor my phone
1. system pannel: very good at finding rogue apps that kill cpu...I highly recommend the pro version, you can get a history of what has used cpu up to a week.
2. Onavo and My data manger which basically monitor my wifi and mobile traffic, Onavo only monitors mobile network traffic and lets you restrict apps to only wifi. however it does not measure wifi use of data. My data manager monitor both wifi and network usage but does not give you any options to do anything with the apps, it basically tells you what program is using data while on wifi and mobile.
If anyone has found a good balance between performance and battery saving, please do share.
Thank you.
I read some other guy also mentioned the all cpus on thing. im not sure but isnt it the same as making both processors work at the same time which leads to phone overheating? I will give it a try though. from what you noticed, do you like it more with both cpu on or is better the way it was?

technically this is how it's supposed to work pic attatched, but I don't know if our roms or even the dual core rom that's out works in this manner, if it did we would be seeing significant battery savings

will see then. hey seansk do you notice some kind of hesitation when trying to unlock the phone? when u press the unlock button at the top. I think that boost app loading thing causes this cuz when have it enabled the unlock button you have to press it twice to work, while when disabling that boost app loading thing all works fine...

I have widget locker and havn't had that problem...I just flashed faux's latest kernel and am in the process of re calibrating my battery, it seemed to jump from 100 to 90 in about 10 minutes!!!!!! now I noticed that happening...but I havn't had time to fully replicate it...i need more time..I believe it might have something to do with fauxes kernel, he mentioned that when screen goes off he it puts the phone into a low power consumption mode, but also has something that when you turn it on, is quick to turn on!!! we'll have to wait and see.
If you've been following this thread, just wanted make a quick update...I want to give you my results with system tuner tweaking. Forcing both cores online is a bad idea. It will literally kill your battery in a matter of a couple of hours. ICS will hopefully be different and utilize the cores how they should be, saving some battery and giving the amaze longer battery life!
On the other hand reducing reducing clock frequency on screen off will help in battery life (obviously).

yes still stock rooted, I put the governor on conservative and put the frequency to 384 or around there, while screen is off.
What helps most I found out is turning off all the radios like wifi and network data, (basically putting phone on airplane mode). Instead of dropping down 15 percent in 6 hours it drops like 3 when I turn airplane on. But like I've said before it's unrealistic I'm always recieving google talk, google voice, facebook updates and I have to have both of these on which unfortunately eats a lot of battery.
I keep switching back and forth between faux's kernel and stock and I'm actually finding stock gives me better battery life for some reason. Even though I set the clock speeds on both at 1.5 ghz.

Battery Life
Major battery drain is the screen, when on eats up all the juice, dimming helps a bit
charge source: usb vs AC charge
usb charging takes quite a while, AC charge quicker (~ an hour)
Also, from my observation, usb charged battery runs out quicker than AC charge
Data Connection, Juice defender helps a lot
turn off sync you don't need, like HTC sense

well the problem is its not my screen. It's when the phone is idle, I usually lose about 15 to 20 percent over night. if I turn off the radios it drops down to about 3 to 4 percent overnight....like I said before I can't turn off the radios...I constantly use google voice, google talk, facebook. And they require both a cell connection and a data connection. I hate to pay for more apps...I've already paid for a bunch of apps to control and see my phone's usage of cpu and battery...is the app really worth it? wish they had a lite version

I have juicedefender ultimate, used it for a while actually...the only good use of it is turns off radios all other things when screen is off..all other things are negligible to battery life...I currently don't use it anymore. I tried multiple things/tweaks with it for about two weeks,...NO point lol...I want to be able to get my google talk message and my google voice texts, it annoyed the hell out of me when someone had sent something like 2 hours before and I would just get it when I woke my phone!!! I tried all kinds of things...but the only thing that actually worked was turning off radios during screen off which I don't want...I can't win lol....I can't have my cake and eat it too!!

while you sleep, you won't be checking for emails will you? but you expect to wake and see emails received.... that is where it comes in handy. with apps like tasker, you can automate some of this activities. tasker + syncer should be a good combo for you.

For what it is worth I am running BulletProof 2.3.1 and last night I took phone off charger at 10:00 PM, alarm goes off at 3:30 snoozing every 15 min until 4:15...Battery was at 100% still. It is now 7:00 AM and battery is at 96%.
This was after flashing back to BP around 8:00 PM.
I've noticed the same type of activity when in Airplane mode. Extremely low power consumption - fantastic.
Is it possible maybe to undervolt the Wifi/BT/Mobile radios? Would that make any difference or am I off base here?

You had something setup wrong then I think.. you can change how often in syncs while the screen is off, the default setting is for it to turn on data for 1 minute every 15 minutes. Most people don't need to know things so bad that they can't work with a 14 minute delay(at worst), and of couse the internet is on while screen is on, when you're actually using it.
I thought I would need to use juice defender, but since I switched to bulletproof, my usage last me an entire day. From 8am till 1am, usually with some to spare. The only tweak I made to cpu was to enable 192mhz, it isn't like there is a performance drop, but it did make a notable difference in battery life.
If I wanted to I could use juice defender to get more than one day out of it, and I keep a spare battery on me in case I really need to use the phone.. but haven't really needed it.

How many apps have you installed?
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.
Delivered using Nyan Cat's rainbow powers.
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?
Delivered using Nyan Cat's rainbow powers.
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.

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?

hey, so i have ran pretty much every "jelly bean" rom out there for this phone for about 2-2.5 months. maybe less. note sure..
anyway, the battery has been horrible! on every rom.. I have a 2700 mAMP battery, and a regular Samsung battery. I have to use both once a day for this phone.. now I have no idea what is making the phone loose percentage after percentage of battery as fast as it has for me, but everytime i post i get about 0 luck from people that either have the same issue, or just people saying they have heard it a million times. i probably should have put this in the "Q&A" thread, but maybe i forgot. can someone, preferably more than one, help me out here?? i don't get how other people say they have 8 or more hours of screen on time with half the battery left. it just doesn't make since. I am loving the android system. but this could be anything! the apps in the background. the kernel, maybe I didn't clean my cache or something. i can't raise my brightness up to far or it'll drain my battery, jamie in the paranoid thread said he had his batter on 100 percent and had excellent battery. so I'm far from confused here. do I need to get another phone, or what. very much apprentice the help from as many people as possible. I love my phone, but I hate that i have to focus on using two battery a day with this phone.
Same here battery draining pretty quick on all jb ROMs.

Battery usage is highly subjective..
It's nearly impossible to determine a baseline Usage expectancy, simply due to the untold number of variables that drain the battery.
We know the obvious power users ....the display, wifi, data ..
But it gets far more difficult to track the Usage after that.
We know that JB is not optimized for our device, but it's getting better, and until we see a true JB kernel with the rom matched to it, the battery is going to suffer.
Then of course we have the many services that users run, along with countless apps ...
Long story short ....maybe a more stable choice would work better? ?
Like ICS, At least until JB calms down a bit ...
I'm actually running Saurom as I type this ...and my battery life is excellent.
JB just isn't quite there yet ...IMHO ....g
to get better battery turn brightness to lowest usable setting, turn off sync for any non essential apps, turn off soft key lights, flash a kernel that lets you under volt and under clock, try different govonors and io schedulers, turn off gps, put in airplane mode when not using. these should help. keep in mind cell signal strength will also impact battery and 4g will kill it faster then 3g. i am on cm9 stable under clocked to 1.18 undervolt all by 25mv( not much change but i like to be safe) ondemand and sio and get amazing battery life.
What's your screen-on time? 4 hours is the close to the limit on ANY rom for our Notes. You have to make sure it's not some sort of confirmation bias going on here.

thank you so much man! i actually went to at&t and they mentioned that too. they said the kernel im using isn't fully optimized for the phone yet. other words. the phone wont support it. he said basic stock ics is the best thing to do now. he also said. these forums are for phones from Europe as well. not just for AT&T in the us. again, the ROMS these devs are making are not supported for the phone, and is kinda like a mimic of something its not. he said jelly bean was out, but i don't know where to get it. can someone tell me how to install ICS, because when I download it, and use KIES, it installs the system, but never fully completes the process.

Sure...
At the top of the general note section, you will find the "note super everything thread"....
Scroll down to find the ICS info you need...
There are many great ICS roms, and you will find that your phone is "MUCH" better running on the software that was intended for it..
Do the homework in the superthread, and read, read, read......then if you have more questions....just PM me, and we'll get ya up and running....g

Battery life is purely subjective. No two people will have the same experience.
Have you used an app like CPU spy to make sure the phone is going into deep sleep? Rogue apps keeping the phone in a wake lock can seriously affect battery life, but its hard to say if anybody's apps are doing that, because we all use different apps and there's no list of apps that keep a wake lock, so you need to use something like CPU spy to see if you are going to deep sleep when your screen is off.
Related to apps as well, don't use any task killers or constantly kill apps when you exit them. A lot of people think killing apps is necessary when it completely is not. Android, since donut or eclair, manages its RAM very well, so that when a properly written app (ie. It's not keeping a wake lock) is in RAM, it's just in a frozen state not using any CPU cycles. Constantly killing well written apps hurts battery life, because restarting the app fresh is much more processor intensive than pulling a frozen app out of RAM. Plus you don't have to deal with annoying loading/splash screens.
Also, like others have said, using the lowest brightness possible, and turning off sync for any unnecessary apps will help battery life. GPS doesn't matter so long as you don't keep something running that uses it. If an app isn't using GPS, then GPS isn't using battery. I always leave my GPS on and do not notice a difference compared to turning it off. If you're paranoid about GPS leave it off, but it's annoying to have to turn it on every time you want to use an app that requires it. You can also disable location access in most apps like Facebook, twitter, etc where you don't need GPS really, and that will make leaving it on even better. If you don't use GPS much anyways, leave it off.
Like somebody said, your cell signal can greatly affect your performance, so use WiFi whenever possible, and even put a data toggle in your pulldown so you can disable cell data when you don't really need it. WiFi in general uses less battery than cellular data, so I use it whenever possible.
I've also noticed that how you use your screen on time also has a great effect on battery life. When I have extended lengths of constant screen on time where the phone starts heating up and whatnot, I see much less battery life than if I just use my phone here and there intermittently. Long stretches of screen on time stress the processor and battery heating them up and making them less efficient, where as short stretches allow the processor time to stay at a cooler, more efficient temperature. If you game at all on your phone, you've definitely experienced this, as you know that your phone heats up due to the extended lengths of screen on time and heavy processor usage. Gaming is a no-no if you're striving for better battery life.
With following those guidelines, my Note sees about 3.5 screen on time with JB on Gubment Cheeze. I would get around that on ICS as well, and I don't remember what it was on GB. Fellow testers and teammates for Gubment Cheeze have seen up to 4 hours and a little more even on JB, so it's definitely possible to have decent battery life on JB.
It really comes down to your own personal usage.

I was not aware of this info....many thanks for the heads up...I always supposed that since the ram was consumed with applications, that those apps were pulling CPU usage from the device...
that is clearly not the case......g
Yep, no problem. If you go back to a touchwiz based ROM and go into the stock task manager, it shows you what's taking up RAM, as well as the CPU usage of each thing in the list. If the apps are working properly, pretty much everything will show very little to 0% CPU usage, and ones that are using it heavily will even be highlighted in yellow or red depending on their CPU usage %age. Unfortunately aosp based ROMs don't have that task manager, one of the things I miss from touchwiz.
Every time a non-techy friend buys a new android, it seems the overly aggressive sales rep that sold the phone to them 'helped' them get to know the phone and installed a task killer, specifically advanced task killer. I always just uninstall it without telling them and see how long it takes them to notice lol.
It's still useful in certain instances, for example if you have an app that doesn't run well but you still like/need to use, but in general practice android does a much better job of managing itself. Besides, if you have an app that you know runs poorly and hogs your processor in the background, but you still need to use it, with most aosp based ROMs you can set your phone so that long pressing the back button kills the current app, essentially making task killers useless.

This is true. What kind of signal strength do you get where you are at? Does your phone bounce back and forth to lte. I have noticed when i go from a strong signal to weaker signals or band switching a lot, my battery drains rapidly.
Use cpuspy, as mentioned, to verify you do see deep sleep. Also, i find if rooted, that seting the min speed to 192 helps quite a bit.
No matter how many forums and threads there is no solution to be found for this massive battery drainage. stock rom vs poison with greenify, underclock, tweaks, lower brightness, other mods, and the battery is exactly THE SAME in both. Draining massivly. I have 60% now, 2 minutes ago when I was browsing in mozzila I had 66%. Also draining when screen off. I kept using the battery with same patterns for a lot of days, adaptive charging doesn't seem to help.. Any solution??
Go back to stock with fastboot and see how it goes.
There's probably a much more convoluted solution out there but it would probably be too much hassle.

Hi guys. Sorry for slow reply. I have tried going back to stock rom and other different roms. No difference. You see the weird part is that the battery lasts the same no matter what you do, stamina mode? same. Nothing running on background ? same. New thing happened: After the poison 7 rom in battery settings ann option "battery care" appeared. I turned it on to see what it does. Only after some weeks it decided to pop up when I plugged my phone to charge. It said something like "Battery Care active. Your phone will be fully charged in 5 p.m Tuesday (example) while it is still Monday 3 p.m. Should I listen to battery care and leave the phone plugged in for 1 day or not? (no matter if it reaches 100%).
This is a bit irrelevant but I am asking just in case: Is your phone too charging very fast ? I have the basic charger (not the fast charge) and I believe my phone is being charged a bit too fast

Battery Care is a nice app if you charge your phone overnight.It limits the duration of your battery charged to 100% by charging rapidly to 90% until a half hour or so before you wake up. To do so it needs to learn your charging habits first. Supposedly this prolongs your battery life. Attached an example. You can see it charges rapidly as well.

I agree it is unrelated. Since your battery problem seems independent on the rom, a few options are left: a rogue app that you always install, something related to your Google account, or a hardware problem.

Is it worth it to try going back to stock again and also unrooting? Or relocking the bootloader? I thought of an app but the only thing that it could really be are the google services , the play store. Messenger doesnt seem to drain much and makes a minimal difference, and with the app we mentioned above I didn't find absolutely anything draining the battery apart from screen and OS (it could also be more than normal)
I did all the trip concept-stock-concept and it seems it is an app right now I'm getting almost the day through and have 20ish of battery, it was easier in my case because I didn't unlocked bootloader or rooted, so might try a full clean reinstall to your phone

I'm currently also having massive battery drain(6% an hour) I tried stock rom, Posion rom and concept rom, sadly all with the same result. I use grenify & fordoze but somehow my phone wont 'doze'/go into deep sleep. I installed better battery stats to check out the problem. On a normal day(one charge) the sumery of better batter stats look like this:
deep sleep 7 hours / awake(screen off) 5.5 hours / screen on 1.5 hours
when i look to kernel wakelocks there is one that is always on top of the list:
bluesleep 5.2 hours 243 wakelocks
Also under alarms there is a suspect:
com.google.android.gms: 864 alarms 1/min
So there are some strange things happening on my phone... really wondering if you got the same wakelocks/alarms as I do
I use greenify and HEBF. Same story here, it seems like nothing changes with battery life. Crazy, only 1,5 hours? My average now is 3. I haven't checked the drainage when screen is off but I did notice similar drains to yours. I think we're in the same boat. I will tell you about the wakelocks, haven't looked into that yet

I've just received my phone for just one day. Backup my TA partition, unlock bootloader and use rootkernel tool to root my devices. I'm using the .331 version stock ROM. Just then I installed the ElementalX app on play store, and surprisingly found that the cpu frequency statistics show that the phone is always on the max freq. So I changed the cpu governor to interactive governor. Haven't test battery time yet. Hope you know this issue, if you have the same problem.

I haven't checked the drainage when screen is off but I did notice similar drains to yours. I think we're in the same boat. I will tell you about the wakelocks, haven't looked into that yet

I'm wondering if you've check the cpu freq statistics. See my post above. If that's the common issue, than the stock rom maybe has trouble dealing with the cpu governor problem.

I've just received my phone for just one day. Backup my TA partition, unlock bootloader and use rootkernel tool to root my devices. I'm using the .331 version stock ROM. Just then I installed the ElementalX app on play store, and surprisingly found that the cpu frequency statistics show that the phone is always on the max freq. So I changed the cpu governor to interactive governor. Haven't test battery time yet. Hope you know this issue, if you have the same problem.

Actually I'm not lowering frequencies, I use EX Kernel Manager to tune the interactive governor according to this post
https://forum.xda-developers.com/nexus-5x/general/guide-advanced-interactive-governor-t3269557
After tuning the governor, it's about 4 hours SOT. Still not good compare to my Xperia Z3, but much better than before(about 2hr SOT)

Well it's not perfect yet but switching off scanning for bluetooth and wifi helped me a lot(under location settings) Also L Speed & Greenify are helping.
Still looking for a way to turn off fast dormancy.
