I have a Thunderbolt running Das BAMF Remix 1.6.3 and Imo's 2.7.0 kernel (I have tried going between Batt Saver/Normal, and now I am on Extreme). I adjusted my brightness of my display to about 20% (instead of automatic), and when I am home I try to be on my Wi-Fi. For some reason, I am not getting a full day's charge out of my Thunderbolt (when I first got the extended battery, I was getting at least 32 hours). I read about people's batteries and I feel people with the stock battery are getting more/equal amount as I am with an extended battery. I tried running Normal setting on Imo's kernel at one point and I did not even last 12 hours, and I was on 3G doing only minimal texting. I tried Batt Saver, and the first day I used it, it was really good (about 10 hours and I was down to 75%, but until I got to 18% or so and then within 3 minutes it was dead, which was weird). But the following day it was not as good as it was, and it died again less than a day. I even tried the Das BAMF kernels and they have similar results. I am also trying to switch between InteractiveX/SmartAss/OndemandX, but I am not seeing too much of a difference (unless someone can give hints on which is supposed to lend to a longer lasting battery). Any advice would be appreciated! (And if you need more specs on my phone, let me know... I generally only text, I do not play games or do very intensive internet things).
I have found the best battery life on bamf stripped v1.1, I get better battery life on that than any other Rom I've tried including stripped v1.7 and all the other bamf versions. I'm running the 4.4.6 kernel, I haven't tried the batt saver kernel from Imoseyon yet. I get 2-3x's the battery life as stock and almost twice the battery life as any other bamf Rom
There are lots of things to consider about your battery life. If you look at your batter use on your phone does it show anything that might be suspiciously draining battery more than normal? If you're using Imo's kernel you can type "12" into the terminal when you are changing governors to see the stats of how long your phone is staying at different frequencies, does it show a high amount of time spent at the higher frequencies? How long does your phones display stay on for?
There are so many things that can drain the battery its ridiculous and randomly I will have severe drains at times that are only solved by a reboot.
eraursls1984, do you have an extended battery? How much battery life are you getting?
Beastclaw, battery use seems normal - nothing out of the ordinary or suspicious is really eating at my battery. As I said before, I am currently running InteractiveX and at Extreme mode, and these are my states at different frequencies:
245760: 2102206
368640: 409810
768000: 58113
1024000: 263351
1222400: 12737
1408000: 72575
1593600: 0
1766400: 0
1920000: 0
Seems that nothing is really running too much on high frequencies, mainly on the lower end. My phone display is supposed to stay on for, I believe, 2 minutes, but whenever I am doing using it, I always lock it.
I heard Autostarts was a good app that could help with battery life and performance (and I was warned to not change any system settings), but I am trying to see if maybe there is anything else I can do to figure out why my battery seems to not last as long as other batteries.
You can try using an app from the market called "CurrentWidget" It allows you to log how much power your phone is using at different intervals of time. My phone generally runs at 40-60mA when the screen is off and its not doing anything and between 400-600mA when the screen is on and I am running tasks. You can use the log to check to make sure your phone isnt drawing too much power in the down state. It even shows you the stats in a nifty little graph form

I have a stock battery and with normal use I get 12-14 hours compared to about 4 when I was completely stock. When I use my phone heavily, constant browsing, I get about 4 hours compared to less than 2 stock. I always have my brightness all the way up except for when I'm in bed because this screen is not bright at all compared to my old phones. Unless you just have to have sense (which to me makes no sense, lol) then I would recommend trying bamf stripped v1.1. I am also not overclocked, I noticed a little increase in performance but not enough to justify the loss of some battery life., however I was going to experiment with it again since I haven't tested the performance and battery life of stripped v1.1 overclocked.
I mean, I have BAMF Remix 1.6.3, which I guess has Sense elements since I do not have BAMF Stripped? I mean, I do not think I use any Sense features or anything like that, so I have no reason not to get BAMF Stripped if it helps increase performance/battery life. Yeah, on Remix 1.6.3 and Imo's kernel at Normal, I had 12 hours on my extended battery... Haha.
Bump - does anyone have Autostarts? Or any other program/app that will help with the battery life, or any other suggestions? I will test the CurrentWidget app tomorrow when I am actually up and using my phone and see if I get similar results or if I find another program is using up my memory... I also recently installed Advanced Task Killer today to help with this battery problem, but I heard mixed things about using it and how it can actually negatively impact the phone instead of helping.

Before 2.2 they were useful on some phones if used right, but its not needed nor does it work on the thunderbolt. If its set to autokill then it will drain the battery faster by running and killing apps, then the phone using juice to reopen the apps that were killed. If you root you can use autokiller (not a task killer) to set parameters for ram memory but I haven't found it to be necessary on the t-bolt, it was needed on my old droid X to keep it from lagging. I would suggest uninstalling the task killer.
Took your advice and uninstalled the task killer - thanks! Anyone else have any other suggestions or advice about my battery problem?
Autostarts is definitely worth $1. If you are familiar with Windows, it's kinda like msconfig for android. It prevents nonessential apps from starting in the background and wasting battery & network bandwidth. If you want to do everything you possibly can to minimize resource hogging, you should get Autostarts.
I downloaded Autostarts - I hate to be asking this sort of question but I am sort of cautious when changing these sorts of settings (because I heard a person who had to boot into recovery because he shut off system applications by accident), which programs should/shouldn't I turn off? I am a little confused how to use this program - did it automatically shut off some programs, because as I look through I see some programs are crossed off in a green line... Any help would be appreciated! Thanks!
Bump - can anyone help me with Autostarts? Any help would be appreciated! Thanks!

Sigh, Autostarts isn't a "task killer"
I stay away from any proccess that's needed to run in the background. Things in yellow, leave alone. IMO pandora has no business running in the background at start up. If there's no valid reason, I kill it.
Tossed from my Tunabowl
I realize Autostarts isn't a task killer (it cannot kill a task if it never opens up, hehe). Thanks for your advice though! The more I was looking at it last night, the more I was understanding, but you just reassured what I was assuming. Hopefully this helps my battery a bit... Or I figure what else makes my extended battery drain faster than others.
Even with Autostarts, my battery life has not improved that much... I have been experimenting a bit with different governors and settings, but now I am back with the extreme Imo kernel and on InteractiveX. Does anyone have any other suggestions? Any help would be appreciated!
I was having trouble with my battery also. I've been lucky with Gingeritis but still the battery was killing me. This may not be an option but the extended battery is amazing. I got the case to go with it and I'm not disapointed. This OS with heavy use also and display at 50% and all animations enabled. Also running 4g all day!

The problem is, I DO have the extended battery and now seeing some of the battery life that others are getting (a lot say 30+ hours, I am barely pushing my phone and I am getting less than 20 at a time).
BAMF 3 RC2, imo 3.3.4, 245/1593, LTE Only mode, auto brightness, twitter sync every 15 minutes, facebook every hour, gmail push, weather every hour, 4 hours of music streaming, another couple of playing, a lot of twitter and facebook, and doing a bunch of other things with the phone, and I rebooted about 3 times. I think I could hit 50+ hours if i didn't OC or reboot.
Oh yeah, I have the extended battery
g00s3y, which governor are you using?
i'm on the same kernel, but using gingerremix w/ a std battery. the phone drains 40% overnight with it being on wifi. (that's with just gmail pushing and gtalk on).
I have a stock SGS2 with a lot of widgets running. I use BetterBatteryStats and have removed the high power usage apps.
Past few days, the phone uses a lot of battery at night. Yesterday it had 32% battery and when i woke up it was dead.
Are the rest of you also seeing this much battery consumption every night ?
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!
I gave up with the stock S2. Rooted it and flashed MIUI to it along with the Siyah Kernel. Now it uses only 6% for the whole night. Battery usage is so much better now.
People having issues with battery should try the siyah kernel and change governors (unless some app was draining your battery)
yeah, actually some new users will experience battery problem. however, some says that when time goes by, the problem eventually sorted out itself.
i am guessing the phone need "warm up time"
I had the same problem with stock rom. you have to remove the preinstalled useless samsung apps. then battery consumption is better.
i am now on cm7. everything is working and around 8% per night with a lot of background processes (tasker, lbe, scheduled titanium backup).
Don't always turn on wifi or data unless necessary.Turn off background sync.This should help a lot even u r using stock rom.Kill tasks with built-in task manager.Make sure useless apps are not running in background.
With these tips,my s2 with rooted stock rom and stock kernel only consumed 3% of battery all night .
i keep wifi or gprs on for instant messaging needs. The Siyah kernel and the lulz governor give amazing battery life because process runs at lower clocks instead of jumping to 1200 unnecessarily.
The stock kernels aren't too bad in my experience.
I think you will find your battery drain will be caused by rogue apps before the kernel.
Edit: why have this phone if your going to turn off gsm and data etc. May aswel turn the phone right off and have zero drain overnight.
A drain of 1-3% per hour with everything turned on is normal for me.

I'm using the Neutrino ROM right now. My phone will get very hot after a while, usually during browsing and the battery will drain extremely quick. It use to not do this. I thought it might be Dolphin HD browser I was using but it does the same with Opera mini.
Any ideas on what I can do to fix this? It never did this before and I'm only half way through my day and it's already at 40%. I use to be able to get through my entire work day and still be in the good 60-70%...
I had this same issue when I first got my Atrix and it started happening after I rooted it and customized it. Even after a factory reset, it still ran hot and the battery drained quickly.
I ended up performing a complete factory reset and took the phone back to get it replaced. The replacement worked just fine, even after rooting it and doing the same customizations I had done with the first one.
If you just got it, I would suggest taking it back and getting it replaced with another one. It could just be a bad battery.
My 2 cents!
Here are a few things to help you diagnose your battery drain issue.
Download "CPU Spy" from the market. This program will show you how long your cpu has spent in each of it's various clock states. This program does not reset it's data until you reset it, and your phone's cpu will not sleep while charging. So charge the phone then open the program and reset timers. Now wait a while and check the stats. Your cpu should be going into "Deep sleep" mode most of the time you are not using it. If it is not 75% or more deep sleep after a couple hours, or if it shows deep sleep under unused clock states then you have some condition (probably an app) keeping it awake.
If you have an app keeping your phone awake you need to determine which one is doing it. This can be done by backing them all up with titanium and deleting a few then testing (takes forever,) or by way of another program. I use a program called "better battery stats" from the market, which is a paid app. This app gives you information on wakelocks, partial wakelocks, and processes that are running. It can be used to find the process responsible, which you then trace back to the app that is using it.
I found out about all this when K9 mail was running away with me. It wasn't too bad as long as I was connected to wifi, but while traveling it would constantly use a very small amount of data and refuse to let the cpu sleep. I deleted it and for about 2 months now I get home after 12 hours with 60-70% or more battery life and about an hour of screen time used. My deep sleep percentage is in the 80's every day. My phone is runnign Jokers's cm9 overclocked to 1.45.
Hope this helps.
Try badass battery off market, it will let you see where it drains
Just switched from Nutrino... What version are you using? EE/GT/GT+? I only used the EE because its stock clock speed. I noticed CPU gets extremely hot with slightest OC. Also, noticed quick battery drain while screen was on (quicker than other ROM's)...

Also, if your using the gt+ version with the over clock kernel like I am using, do the phone a favor by keeping the phone underclocked at 1000 MHz instead of 1450 MHz. That will help the heating up too. That's what I do. Battery is great too.
Sent from my Atrix with XDA Premium
As Voelker does, I have the 1.3 version of Neutrino but keep it clocked at 1Ghz max with SetCPU profiles most since any overclock tends to get warmer than I want. I havent had a temp crash yet, it's just me being paranoid sometimes. I do set it to 1.3 when I am playing games for smoothness, but I havent noticed any unusual battery drain, just more heat than I want.
Hey guys, I was recently testing different android GPS apps (copilot and sygic so far ) and I noticed my phone warm up noticably upon running those apps with GPS on. I tried flashing to a KH3 modem firmware (as suggested by some members of these forums) but that did not change the behavior. I tried two different programs and it overheats in both. Is this normal behavior? !
It is kinda normal.
Sometimes it gets a little better when using another modem but not really much better.
Good luck
Dip
It's actually two problems.... the heat and the rate at which it drains when its hot... I went down from 91% to 55% in a 1.5 hour trip with nothing but GPS on..
1) Modem has nothing to do with GPS.
2) Yes, normal for phone to get hot when you use CPU/GPU intensive apps, tho this might be a rom/kernel issue. I find mine doesn't get above high 20's C when using GPS for a while. Do you find the phone heats up a lot when you use other CPU/GPU intensive apps ?
3) And yes, GPS does drain a helluva lot of juice. Best thing you can do is get a car charger & plug the phone in while you're using GPS to offset the drain. Is losing 36% over 1.5 hrs of GPS use normal ? I don't know that there is a 'normal' so far as drain is concerned (it's variable). I guess other people might be able to give you a better idea of that than me, or you could try other roms & see if you get similar results with those.
Anyone else had a similar experience?
For the heating problem, you should try speedmod kernel, or phenomenal.
And if you have any doubts about the battery drain, take a look at, let say, a Garmin GPS device. Unplugged they don't last more than 3 hours. And they have an awful resolution, a tiny processor, don't use network, and a dedicated OS.
I recently noticed that my EVO 3d began over heating at moderate use. The battery isn't what's hot though. It's definitely not software related because it just started to and I've been running this Rom for a week now. Does anyone else have this problem? Or what do you think is causing it?
Mine overheats, too. Especially when I am just browsing the internet or playing a game. Its probably just the screen though, because when I check what uses up battery power in settings, the screen uses up the most.
I had this only when I was using certain ROMS. (i.e. AOSP GB or CM9)
Also, when the CPU is OC'ed it tends to get quite hot for me too.
Since there isn't much info from your end, there's not much else I can say here
Thanks I just found it strange that my battery didn't get hot, but the rest of the phone did. I'll try a different Rom and see if that works
Btw I'm not overclocked. I'm running chubbz Ville c2 port
