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).
Anyone else get terrible battery life with go launcher? I absolutely love the launcher but its almost not worth it for the extra battery drain im getting. Id like to see what everyone elses experiences are with this launcher
i dont use it anymore but when I did have it, my battery did not drain any faster (at least not that I noticed).
I just went to go launcher ex and it seems to be draining a bit faster but too early to be entirely sure
I wouldn't say terrible, but the battery drain rate did increase. When installed, I saw 2-3% drain during idle. I switched back to LauncherPro and it has gone back to <1%.
I'm in a bad service are at the moment but I can for sure say it's absolutely guzzling it right now with internet significant use. I think I'm going to just go back to touchwiz or try adw or some other one. 5 rows for apps and customizable themes isn't worth the drain.
yes I have notice a atleast 3% drain on idle. I absolutely love that launcher but cant do that. In 3 hours I was down to 88% with little use...
Is there not a way to get an extra row of apps on TW Launcher? How about the bottom row at least?

I love Go on this phone, but I don't use any widgets and keep syncing off. Overnight after 8hours I only loose ~2-3%
So you're saying everything setup identical between Go and TW or another launcher you see a noticeable idle drain? Would love to see some numbers showing that.
Yessssss!!!! Between the launcher and all the stupid Widgets I found myself force stopping constantly...extremely annoying if I may say so...

Simple question for all the experts...
If two different Roms are running the same Kernel, should the battery drain be that much different?
Im running REZRom currently and thinking about switching to Bamf 2.1. i'm sure both roms are smooth and fantastic I just want the one with the best battery life.
Any advice would be great, thanks in advance.
You should get good battery life on either. That is depending on your usage and setup of course.

Battery life with same kernel should not vary too much from ROM to ROM. Depends on how much "stuff" is running in bakground that might be using the battery up. The kernel makes the biggest difference since it controls the whole system. I am personally using Scotts CleanRom Developers Edition (Senseless) and it is great! I get a solid 13+ hours with moderate use (some calls, lots of web, and a few games) and thats on 4G for 11-12 hours of it! If you use wifi you probably could squeeze another hour or 2 out of the battery...
This is on clean rom dev edition. 2 hours screen on time so far with standard battery. I use 3g normally unless I need 4g. I also use juice defender ultimate and keep data off while not in use.

While there are a number of tweaks and apps you can use (like SetCPU) to improve battery life, it's true that the kernel has more to do with battery life than that ROM itself.
Sometimes a rogue app can prevent the cpu from idling or prevent the phone from entering deep sleep mode. This happens on mine occasionally, and you can usually tell from the extended battery graph because the phone will show as awake for large periods of time, even when the screen is off and it should be in sleep mode.
I decided to give the standard Sense UI a go (even though the minor hickups and cube effect bug me) but I am astounded at how much more battery life I am getting.
I have used Nova Prime since I bought my DNA and got between 6 and 7 hours at the most.
Standard Sense (with root) and I am at 76% after 4 hours and 37 minutes.
Anyone else getting similar results?
I have been on Sense since I got this thing and have been incredibly impressed with the battery life. Hopefully this doesn't change if AOSP comes out.
I have also noticed the same thing. Also when I was using apex launcher it seemed like swiping between screens took just a little longer. I think that sense is just snappier.

Have had the phone for two days now and have been impressed with the battery life. Based on all the negativity I was expecting a poor experience. I have been using it fairly heavily (initial set up, playing around with it, downloading all my apps, etc.), although not too much 3G/4G use.
battery life has been exceptional for myself. I'm comparing it to the galaxy nexus.
Sent from my HTC6435LVW using xda premium
I noticed the impressive battery life also, but I've been running ADW due to the familiarity of it and the customization. I'll have to give sense a shot for a few days and see if it gets even better! I noticed too, that non-sense launchers seem to run a lot slower. My Gnex is actually more responsive running ADW than my DNA. Only thing I can figure is that the sense we have was designed for the 1080 screen, and perhaps optimized to use the quad core proc better. Hopefully the other launchers will adapt to this in a timely manner.

How to literally double your battery:
1) Add Facebook mobile site shortcut to home screen.
2) Disable built in fb app
On the Nexus/SIII I was one of the people who blindly said "FB just drains battery" but I decided to give it a shot. I shut all notifications and refresh and location off for the app from the getgo. I'm a student so I have similar usage patterns every day. With FB app installed I came out of school with somewhere around 45% left two days in a row. Today, with slightly less usage in the morning, only thing changed is no FB app and I had 83% left. Mind boggling difference. :/

you would think if that was the case, that FB would be number 1 on the apps list for battery usage. Maybe it just doesn't let the phone sleep properly.

I am rooted and am using Nova Prime. It has worked really well for me, and I find the battery life has been decent, especially after the first couple of days. I will say though that in the battery settings, under app usage, it shows Nova Launcher as the second highest app at 9%. Not sure if that is normal or not, but it does seem higher than I remember with my other phone.
I'm using Nova launcher and it's usually at like 2% on my battery usage list. My highest is "Kernel" with like 38%. I have no idea why Kernel is so high.
I also use Nova and will not go to sense because I like 6 rows of icons on the home screen. This phone is so long I hate wasting it. I'm getting 15 hours with 2-3 hours screen time with 15-20% battery
left the last 3 days. I can't ask for more. The battery is more than ample for me, and has exceeded my expectations.

38% does seem high. GSam shows around 15% for me. How long have you had the phone? Is it possible that it is still settling?

I simply told the FB app not to automatically sync anything. I update manually if/when I want.
I noticed that Nova was 10-20% on the battery usage list as well for me.
I've also noticed the amazing battery life. At first I thought I might have been making a huge mistake by getting the DNA, but now I have no complaint whatsoever.

Wait, so you're saying that even though you always had all notifications and refresh off, the FB app still used up that much battery? I used to be one of those people too, and I always turn off everything from FB. My battery is doing quite well, but hey, constant improvement is always good right?
I've tried both nova and apex launchers on a previous phone and i found that nova is a battery hog. I was missing some of my options that i had set up on apex so i had to install it again, I'm enjoying plenty of battery life but i also only average 1-2 hours on screen on time.
also you can change animation speeds both in the dev option in ICS and in apex launcher settings

I'm getting these exact same results.
What has been people's experience with battery life with the different ROMs? I've been on AOKP for awhile, and the battery, quite frankly, sucked compared to stock. I'm currently on PA and am getting just under stock. For me, battery life is first priority, even if there is occasional stutter. Testing battery life takes a long time, so I just wanted to see what others have been seeing. I would stay on stock, but I really want Tablet UI and real setting toggles.

You sort of want your cake and eat it too. If you want a ROM full of features and packed full of unicorn blood and the tears of leprechauns something is going to have to give and that will always be the battery life.

I'm addicted to my tablet... I've been using it without stop for the last three hours. This are my results with Paranoidandroid:
Very similar with stock though. I think I could upload some as well.
I'm pretty sure this is stock. Not a lot of difference as I said. Both of the images are with very heavy usage, I mean, screen on all the time, but almost the lowest brightness. With the screen off I get almost no drop.
(I couldn't attach the image in the previous post)
Battery life will always be a combination of idle drain + screen on drain. THe most important is obviously how long you can actually use the tablet (screen on time), but you also need good enough idle drain to not lose hardly any charge between when you use your tablet.
The more features you add the less battery life usually is. So either keep PA so you have the tablet UI or use a ROM that is very close to stock, like the stock ROM from scrosler or Muzzy's ROM.
A kernel can also have greater effect on battery life. If you want the best battery then go with KTManta kernel. Use either PegasusQ or ktoonservative governor and add in some undervolting to lower power draw. Using this combination I was able to get over 13 hours of screen on time in 1 charge. Idle drain was about 1% every 8-9 hours.
Personally, I've found that my battery life has improved maybe 10% since running cyanogenmod. If I'm really lucky I can get 7 hours SOT. Not a huge improvement over stock, but its definitely better.
Its worth noting that I use the "performance" CPU governor, which is supposed to be a battery killer. Strangely it doesn't seem to make much difference for me though, it just makes everything quicker!
