I normally don't do this but I have seen this question 5+ times in the past 7 days. Do a search my friend.

My suggestion...
is to try Nitro's EC01 Rom, as well as Nemesis2all's updated kernel (Which gives you the ability to change volt settings, speed, etc) which can really improve your battery life.
Ya I would say try Nitro's Evil Fascination ROM and Nemesis2all's kernel as well. My battery life is pretty good without messing with the voltage. If you're still not getting great battery life you should a) download Juicedefender. The free version does an amazing job for me or b) do some research and try to adjust the voltage settings.
I just started using Active Apps from the market. I guess it's a Samsung product that you can use to replace Task Manager. Whenever I don't use it, my battery drains real quick, and without a specific pattern. When I use Active Apps, and use the Ram Manager level 2 kill, my battery drain instantly gets much lower. 5 hours unplugged yesterday only drained my battery like 11%. Compared to up to 30% otherwise. Hope this helps others too!
Try the app "juice defender " in the market. It makes my battery last 2ice as long

How long after battery calibration should I see a difference?
I need to reiterate what has been said: first, install Juice Defender and learn to tweak those settings, it's well worth it. Second, undervolt that puppy with Nemesis2all's latest kernel. At idle, my phone might last 48 hours [not tested].
I only ask because when I recalibrated my battery (charged fully, wiped stats, drained battery, fully charged with phone off) my battery life is worse

I update OTA last week on Verizon to Froyo 2.2. My battery was overheating and draining like crazy from my CPU usage being at a constant 99%..
I found the source of the problem. An app I use for facebook called "FLOW". The CPU usage was cut to 20% when I killed it with "Advanced Task Killer".
I resolved the issue by: Opening Flow.. going to Preferences.. Notification Settings.. Refresh Type.. Checked Periodic Polling (I was using Gmail Experimental previously)
Hope this helps...

I currently have my eris rooted, flashed to kaosfroyo v35-1, which I hear has crappy battery life anyway and i hope v36 is on the horizon, and using setcpu. Not doing any crazy overclocking. And no change in drain or saving since installing it. I tried re calibrating my battery a few times including battery stats wipe.
I still seem to not be able to get the battery drain to slow down other than turning off the 3g when not using it. Is there a 3g managing app? I haven't been able to find one. And any other suggestions im definantly open to. (The collins battery tweak wasn't working out as far as getting it set up and running.) Also when I reboot the phone the battery gains about 10%.

Do you have the 50% time without signal bug? Go to Settings->About phone->Battery Usage and check under Cell Standby.
Nope. And its been 5 hours since unplugged. 3% time without signal.

I just installed the new Rom TRIGGER 3.3-beta. This rom is very fast and the GPS is great. I also put on bali 1.8.4. But the battery drains fast. If you guys tried it out, and found a way to save battery can you please let tell us what you did to control it. I know its in beta version and is being tweaked on.
Thank you
Yea Im using the same Rom. Hate to break it to you but the battery life on most all android devices sucks. I have had 5 different android devices and the battery sucked on all of them. didn't matter if it was stock or custom Rom. ether way these devices just have ****ty battery life. You can make it a little better by turning down brightness and messing with other settings but when it comes down to it. it still sucks! Just my 2 cents!

Did you recondition your battery after flashing? I've had pretty good battery performance with the Bali kernels. I also tend to use the KB1 modem. It seems to give me the best battery. But each phone is a bit individualistic, and what works well for someone may not work as well for next person.

This is untrue as I have owned an android device since the G1. The battery did suck on the G1, but by no means does the battery suck on every android device. My guess is you probably never calibrated your battery or you just used it very heavily. There's also the possibility that every rom you tried sucked on those devices. I have consistently gotten a full day or more with Bionix NextGen V2 with the Bali kernel with moderate to heavy usage. It is true if you lower the brightness,turn off wifi,bluetooth and gps when you aren't using it that it will increase your battery life though.
I have reconfigured the battery and have the brightness turned all the way down. Dont use WiFi but battery still sucks compared to other smart phones.

can any of you post a screenie of this rom pls
Battery usage is hard to compare since there are so many variables. In my experience I generally have better battery life when visiting my parents. The area I live in is somewhat of a black hole for signal and I notice more battery drain here with the same rom/kernal setup and similar usage pattern. I believe the weak signal here causes a higher battery drain over all.
Of course this might not apply to your situation but it could be worth considering.

I'm not going to argue with you, I'm just going to state what the facts are.
THE BATTERY DOES NOT SUCK, MOST LIKELY IS USER ERROR
Lol. It isn't user error. I think you might just use your phone more heavily than others. One thing you have to realize when comparing the battery life of the phones are a) battery size, b) screen size, c) smartphone or stone age phone, d)**** you've done to the phone including ROM's/Kernals/Apps/Sync.
Personally, on days that I am working, I get about 8-10 hours out of my battery before it dies. When I am not at work I get about 23 hours out of my battery.
what is the major difference between trigger 3.2 and trigger 3.3?
Try using overstock instead, I've had pretty good battery life with it.
Im running trigger3.3 beta with overstock and the battery is great.

so any new tricks that you guys have found to boost up this rom?
might try this later, i could say the battery on my vibrant is better then the iphone and ive gone through all versions of the iphone.

bahaha you must be kidding. like someone else said, it depends on soooo many variables and phones. I was running trigger rom and overstock kernel and was going down about 1-2% battery every hour while screen was off. I listen to pandora every morning for an hour to hour and half and would go down 5%. I've sat on the web watching tv on TV shows stream app for about 1-2 hours and went down like 15-20% when brightness is lowered.
It's all about the brightness, killing apps that enjoy sucking battery life and enjoy run constantly, and running an OC/UV kernel. You can also change it from the usual 3g/H connection down to E (edge) which uses alot less power also. Turn off or turn down auto sync on certain apps like facebook from every 10 minutes down to every few hours.
The screen is the biggest power consumer, so lower that, set it to automatic or all the way down to lowest brightness to save quite a bit of battery when using the phone.
Usually the second largest power consumer (if ur not a huge user of just one certain app) is when the screen is off and the phone is syncing and just running android. the solution is If you can find a decent UV kernel (overstock for android 2.2 was what I was using when on 2.2), you can slow your CPU down. Like on my vibrant I made a profile (on the SetCPU app) to undervolt it from 1,000mhz down to a conservative 400mhz max and 100mhz minimum when screen is off. This is very easy to do. sometimes I'd watch shows on that. I usually left it at a conservative setting and 800mhz and 100mhz min all day long when screen was on, sometimes at 400mhz if i wasnt doing much. It worked wonderfully for me.
Moral of the story, there are plenty of things to make your phones battery last longer than it normally would. The big one probably to get a well known kernel that can UV, then get SetCPU and make a few profiles to make your phone use less power.
BOOM!
Hey,
I flashed lighting rom yesterday and was my first custom rom I have ever experienced. I love it, however battery life is worse than stock rom and I have done a recalibration of the battery. Is there something im not doing because I was lead to assume that my battery life would improve.
If there is something I am not doing, please enlighten me.
Thanks

From my experience a custom rom uses power pretty much the same as stock but once you root the phone you can freeze processes which then save the battery.
On stock I was getting screen on time of about 4.25 hours but now on villain rom I got just over 5 and still had 22% battery left.
I use ant tek app manager to freeze the processes.
I am sure people are going disagree with me here but I really think people are expecting a little too much out of this liddle-o-battery, if your phone is running at 1.2 all the time then its gonna suk-da-juice. I don't pick ROMS based on its battery performance as most now have battery optimisations cooked in as soon as they are found anyway. I just make sure I have some practical SETCPU profiles set to keep those megahertz at bay but also charge my Phone at work so it don't cost diddly anyway.
I also have a spare batter just in case
When the phone turns on, the camera makes a noise like it is coming on, is this normal? If not this could be it, however I have also noticed that the drain is absolutely massive when the screen is on (almost 10% in 20min)

To have ANY idea about whats going on with your phone post screenshots of settings > about phone > battery.
Of both the graph and of the list of %'s
Also what rom/kernel/modem
Only thing which is suspicious is that display is a lot higher than normal, possibly due to the crt bug where auto brightness is not very good, have now set it to manual.

Not a clue, without screenshots I cant know how you are using your phone etc
Fair enough, I may see how my use is tomorrow, I have installed juice defender so hopefully that will help things, I really like this ROM
I flashed litening rom 2.0 then cwm flash update 2.1 + 2.2 coming from stock rom noticed a battery life increase of about 50%.
I have been flashing back and forth ROM and Mods... I felt my battery getting worse compare to stock (stock Rom removed lot of ATT craps and other unused app).
Now doesn't what Rom i use: S8, Unname and CM7. My battery died at the end of the day which should last 1.5 days as my normal use.
Hmmm... well I jumped onto the ship already.
But I have to thanks for all developers that cook Rom. You guys are best.
Battery lifestyle will improve once you build up cache. Was battery life good when you first got your phone? Probably not. After awhile battery life gets a bit better.
Sent from a Galaxy far far away...
I noticed the same thing when I flashed from UnNamed to S8.
I followed some other users' suggestions and reflashed at 100% battery life, allowed the battery to discharge all the way until the phone died, then charged all the way to 100% again without taking it off the charger. I just got 25 hours with moderate usage and about 4 hours of screen-on time.
download the batteryCalibration app from the market, it requires root and makes you charge to 100% first. After that let it drain and it should do better after a couple cycles.
If you delete your battery stats in clockwork the phone relearns them and works better. But it will be ****ty for awhile

None of these do jack on our phone. I've read the kernel source for our fuel gauge driver, clearly none of you haven't and are blindly applying HTCisms to a Samsung phone even though I've posted MANY times that diddling with batterystats does NOTHING WHATSOEVER on this phone.
If someone's experiencing bad battery life after flashing a new ROM, especially a debloated one like Unnamed or S8, they most likely installed a drainer app.
If you run Skype, nuke that crap from your phone ASAP. It's a known battery drainer, and it's particularly insidious because of how it drains the battery - the usage shows up as Android OS but it's Skype that is at fault.
I have updated my S2 with the official ICS. My battery life is now so poor I struggle to get a full day's use. Before the update I would get about two days with moderate use. I have read that the battery life should improve with ICS update. Can anyone explain this and give a solution as it is very frustrating.

try some batt monitoring apps from market and see whats draining ur batt and resolve the same either by force stopping those apps r deleting them if u find they r batt drainers
and also for ICS it requires at least one r 2 recharge cycles for things 2 settle down

Samsung Official ics will always be a battery eater.
Suggest you to root your phone and install a custom rom like wanam/slim etc. These will remove all unnecessary bloat wares giving u better battery and performance. (Do remember to read all the necessary info before u root).

still you can try custom roms because they give better battery life

Have you tried BadAss Battery Monitor?
imho: too many running services in background.. try to kill/freeze unnecessary apps(use link2sd), but most important thing is it seems that current ics is not optimally written/optimized, most kernel can help minimize this effect (but minimal e.g. speedmod)... if you can bare with this condition you ics is for you.. but if you are expecting an optimal performance of your sgs2, you should consider reverting back to gb ..
If you wish to remain on Stock Rom, please root your phone. CF-Root kernel here

Then use Titanium Back to freeze unwanted apps which drains your battery. List of applications safe to remove here.

According to CPU spy deepsleep is at 42%.
According to badass battery the battery is consumed as followes: 60% kernel and rest of apps about 9% with none more than 1.5%. Balance is consumed by screen 15%, phone radios 3%, phone 13%

Deepsleep with 42% is far to little
Find out, with process drains your battery.
Use BetterBatteryStats und look for kernel wakelocks after display is 1 or 2 hours off.
I had the same problem a while back and battery would go down to 20% in about 5 hours. Did a factory reset because when I upgraded, I didn't wipe cache. I read somewhere that old gb code could cause issues.
After the reset, phone works great. I get to 50% battery in about 13 hours. If you can, give it a shot. Of course, back up paps with Ti, otherwise reinstalling them is a *****. :banghead:

I'm quite satisfied, after first cycles now with stock Italian LPF and Phenomenal 5.4 Medium Kernel I have very satisfing results (I forgotten the phone on this night, in 5 hours it drained at least 1-2% of battery).
In normal operativity I'm on 13-16 hours with 1650mhA battrey.
Thanks will do that and post results for further help.
Battery life has now improved to about 15hrs since taking the battery out for recalibration and putting it through a few charge cycles. But this still feels to low.
Ps deepsleep still at 42%.

oooor you can downgrade to Gingerbread and get a custom rom/theme for that awesome ICS feel and at the same time get awesome battery life
I backed up my data, did a factory reset, restored my backup, charged the battery and now the estimated battery (@ 64%) is about 30 hours. So it seems my battery problem is sorted. Holding thumbs!

I suggest i apply all the Tweaks as possible first, secondly install a cok kernel like Siyah, then see if there's any difference
