Ok, I have been flashing for a few months trying to optimize my phone. My last rom was serendipity 6.2, with sp 59 and jl2. I restored to stock (bc I wanted to try something else and hadn't done that in a few weeks) my battery life on serendipity was atrocious.. 6 hours with medium usage. (hardly any calls or messages, looking things up or reading xda briefly) . I spent today on stock, after about 20 hours of light usage I am at 60% left. Now I did flash with a full battery serendipity, wiped battery stats and cleared cache and after several charge cycles and a few days battery life was still awful. I was about to get a new battery. Now I don't mean to single out serendipity, I've had bad battery life on paragon, dilli, and a few others (this time it just got unbearably bad), but why should battery life be so bad on custom roms? Am I alone on this? I hesitate to flash again bc I'm loving having a phone that won't die if I touch it, but I miss the functionality of the device with a custom 2.2.1 on it. Advice or opinions please.

I'm having the same problem. Everybody keeps saying they've got excellent battery life and what not with custom roms but mine doesn't seem so good. Wifi is off, I've wiped battery stats, I've used the rom for several days letting everything get situated before I begin thinking about if its good battery life or not. Maybe I'm just expecting too much or I watch my battery a lil bit too much, idk it just seems pretty bad. If I stay on the internet for 20 minutes I've already dropped about 3%

The normal Batt live on this phone with normal use is between 12 to 16 hours
I'm thinking part of it may be psychological and part may be usage.
Psychological in the sense that I have an expectation of an improvement, practical in that with my stock rom I haven't reinstalled certain apps like xda and pulse where I spend a lot of time reading and thus using the screen.
That being said I was still experiencing drains of 8% or more per hour when the phone was idle, wifi and gps off.
There is a way to check the cpu's time in each state, but I can't remember where the file is. If someone can, please let me know. I'm curious if under the custom rom my phone wasn't properly scaling down.
I'll probably flash something new tomorrow morning unless I see something shiny and new in the dev forum.

So 6 hours seems a bit low then? Could it just be a cumulative effect of flashing rom on top of rom with restoring to stock?

Yeah 6 hrs does seem a bit low. There are many things that can contribute to it. If you are bouncing between H and 3g on a custom rom will drain it like crazy, I had to disable H and stick with 3g and that helped. could also look at OS monitor to find what is running in the background.
Ok, I did notice that recently I was jumping between h and 3g. I was experimenting with some of the new modems. Should I try finding a better modem for my location?

I would try others, as well as disable H in the hidden menus, and see how it fairs
@ zelendel.... so by H i assume you mean data... i see alot of back and forth when data is on. i know when data is off i'm still using wcdma from the gsm status, but it doesn't show the 3g icon.
i need my data because i'm from the states but living in australia and alot of my comunications are thru email/facebook.
when i look at battery usage i see rarely more than 5% from cell....usually 90 something from display ( i fiddle with it alot).
can't expect too much cause it's a powerhouse with a tiny battery........
for me the big Q at present is... can we top up the charge regularly or is it always best to let a full cycle run? if i knew it was fine to keep it topped i'd stay 50%+ most of the time i think................
It is not great to keep it topped off. The lithium battery will wear out faster and lose charging capacity over time. this process is sped up the more time the battery spends at a high charge

Visit the Samsung web site and read the battery specs for the Captivate. The stock battery is only rated for 5 hours and 50 minutes of active phone use (which means the display is active). In sleep mode (display and other features of the phone are shutdown) the battery is rated for up to 300 hours (12.5 days).
I have NEVER seen a stock Captivate last for over 3 days in sleep mode. As for active phone use (display is active) my experience with several of the custom ROMS (Cognition, Paragon, Andromeda, and now my favorite, Continuum) is that the battery life is either on par with the stock ROM, or exceeds it. The kernels on some of these custom ROMs are more efficient than that of the stock ROM due to the many tweaks and cleaning up of bloated apps and code by the developer.
I can't bring myself to keep a stock ROM now that I have used some excellent custom ROMs like those I name above.
As for flashing custom ROMs and seeing fast battery drain goes... I have had that experience with those I listed, but usually I was able to resolve the issue by ensuring my battery was at 100% (meaning showing that amount both on and off) and reflashing, or finding the cause of the high battery usage and going from there (e.g. I have had to reflash modems). Another thing I do, mainly out of habit from compiling code and deploying it in dev and test environments, is to make sure that I am working from a known good baseline ROM before flashing a custom ROM. In this case I always return to the stock ROM you can flash through Odin One Click. That way if you have battery problems after flashing a custom ROM you can have a good idea as to what is causing those problems. This is, of course, just a matter of personal preference. Some have repeatedly flashed one custom ROM over another with no issues. YMMV

No what I mean is disable HSDPA I think is the term lol. Sense you go back and forth I would say to disable that and just use 3g only.
If you don't know the code to get too the menu download sgstools it has the hidden menu keys.
Sorry but where can I find the hidden menus?

I am the opposite, I got horrible battery on stock. Could not even make it through my work day without it dying on my way home unless I charged it midday. Now I am running Serendipity 6.2 and unplug at 7:30am and it is now 8:30pm my time and I have 30% remaining....
I have also tried other customs roms with noticeable improvements in battery life over stock but for me Serendipity gives me the best performance and battery.

try apex5.1 room with tl3 modem comb
i used about 50 phone call, 2 hour websurfing, email sending, checking.
i still have 41% left, 1day 10hour 50 min.
Could I have a faulty battery? I rooted and rommed cuz of my battery life being terrible but It still is bad

I had the exact same issue as you. I tried Darky's 9.3 first, then Serendipity 6.2, then Cognition 4.2.1. Each had major battery drain, meaning 6-8 hours with moderate use, and even without any usage it would drain 25% over 3 hours.
Use One-Click to flash back to stock JF6, then immediate do a Master Clear from the One-Click program after it has finished booting. Obviously move everything to an external SD or the computer prior to all of this, and make sure the external SD and SIM are out when flashing.
My battery has lasted for 14 hours today, and I'm only down to 54%. This is with about 1hr 20min screen on, ~30min voice calls, and always connected via 3G/H with background sync on, weather widget, and moderate web browsing.
Current setup: Serendipity 6.2, Speedmod K13C, JK4 Modem
Trying again
I couldnt keep myself away from custom roms, how i missed tethering, the custom theming, non marketplace apps and so much more...
Im trying Dilli's 7.1.1, bump charging at the moment...
Last night I drained my battery to 5% when i finally fell asleep... 6 hours later it was at 4%. Finally it drained and would not power on at all. Not even the backlights. Plugged it in for an hour and thought to take the sim card out so i would have a phone for the hours it would take to charge. When i plugged it back in the phone jumped from approximately 10% to 40% charged...
Oh well.
I have also been bouncing around flashing diff roms like crazy. I have to say though, I am using Continuum v4 with Hardcores speedmod Kernel K13D. I have been doing pretty good on this combo. Lasts for most the day with normal use.
^^^^
I really hope so. Even with custom ROMs, i am not seeing a major improvement in battery life. Phone looks very pretty though.lol
Ive been reading about the nexus Gingerbread update.. and the reaction has been mixed so far.
I'm not understanding everyone's issue with battery life.. Even stock.
I am running the seido 1600mAh battery but its only a tiny bit bigger so..
Yes it probably will. Gingerbread has features etc that will make it better. However, we will not see that until gingerbread kernel source is actually released from HTC. CM7 will be using the kernel from 2.2 until then.

A custom rom won't help battery life that much. What you need is a custom kernel and to tweak setcpu settings. I'm getting much bettery battery life on the 1.5 ghz oc kernel running @ 1.4 and 300 mhz with screen off then I was stock

Custom ROMs will help when we get closer to AOSP. Right now we are just kind of fading out Sense but, taking it out completely should help a little.
But getting back to what you said, right now, custom Kernels are the number 1 way to save battery.

Wait. You overclocked and are getting better battery life? Crazy. I just rooted yesterday, and this is my first day with my set CPU settings. Hopefully it helps, but we'll see.

I don't understand how people think just because the Froyo kernel source came out that we should all be getting 3 days out of our battery now. The INC I had wasn't giving constant great battery life until about 6 months after I got it. It will take time for the battery life to improve. And these roms aren't highly modified at all, it hasn't even been a month, we are all learning about this phone and what it can and can't do. Give it some time and you will see battery life improve, it's not like GB will drop and everything will magically get better.
I don't think battery life is too bad. Better then my old EVO with a larger battery. But I suspect that is because of Sprint's network problems. Made that poor EVO work way too hard for data.
I flashed my kernel recently and created a setcpu profile for 245mhz min/max when the screen is off using "smartass" governor and over all i am using the smartass governor max cpu 768mhz. Battery still kinda crappy. Even just playing mp3s the battery drains fast. Ive been keeping the phone in exclusively 4g and now i am trying 3g. I get very solid 3g/4g coverage in NYC. I donthave many apps running in thebackground. Just have my google sync on and i think facebook... thats about it. Also keep my screen around 20-30%. Ive also done a few full discharge cycles on the battery info and deleted the battery from the CWM recovery menu.
**P.S.- Sorry if i am sounding impatient. I am new to the Android camp. I came from the iphone 3g.iPhone 4 camp. Battery is something i never really had to worry about. Just sucks i have to be more proactive to make my battery last me through the day. Luckily i have access to chargers everywhere... but i dont always want to have my phone plugged in.
Same here, came from the blackberry camp where 3 days per charge is normal. My battery life isn't bad to start with (9hrs) and is only getting better with the new kernel. Still, i think every little bit helps so i hope gingerbread comes sooner rather than later.
In all reality. The screen is what takes up most of the power. I think for me, typically the screen is around 60 - 70% of my battery power. This is a big 4.3 in screen. Having chargers is handy, and the faster the charger, the less you have to have it plugged in. Are there any reliable 2 amp chargers out there?

Ya. Oc kernals usually undervolted and have other battery tweaks. Its setting run real low with screen off. I have my brightness kinda low. Screen off thirty seconds but that's about it. I work in 4g area live in 3g. 4g is tolerable now with this kernel
Sent from my ADR6400L using XDA App
Smartass is still kinda broke from what i can tell. I found luck using undervolted kernels specifically the 1.2ghz kernel from DAS BAMF and Adrynalyne's kernel too
gingerbread seems to have very good power improvements. idle power when phone is asleep seem to be extrremenly low, around 3mA. this is very good and will help you guys when you get GB.
possibly a parallel...
One year age, I bought the HD2 on T-Mobile. Guess what? Poor battery life, etc. Then the update came through and battery life was BETTER. Today, I now am with Verizon and the Thunderbolt. Battery life could be better. And Android 2.3 will be released soon to the Thunderbolt. Will that help battery life. Hope so. But if not, I can get a spare/bigger battery. Admitted, we have no 4G in my home area, so I do not know what impact that has, but my battery life seems like it is improving just because of the charge/discharge cycling that happens normally. And yes, I'm also aware that both are HTC devices but running different OS's, but an update is just that, an update.
I think that it's sad that HTC put in such a low capacity battery and I don't think software optimizations will cure a poor hardware decision. A true OEM 1600 or 1700 mAh battery will make some improvement which seems doable. My Droid 1 had significantly better battery life. If you use 4G as I do, it drains the battery quickly. I use my TB like a Blackberry for email, checking one account every 10 minutes which is far less than Blackberry. Still, using 4G for this, music for my 30 minute commute in both directions and a few other things puts me at below 50% battery life by the work day afternoon. I don't know why HTC put in such a small battery and I'm guessing it has some connection with why they had so many extended batteries to sell on launch day. I have one. Makes the phone noticeably larger, not as bad as I thought although unnecessary... but the phone does last a long time and no worry about battery life.
Android 2.3 is supposed to come to us in Q2, so in the next 2 months. It will more than likely have sense, so it will therefor still drain battery.
My girlfriend pulled 36 hours yesterday on her TB, completely stock. She stayed at a relative's house who didn't have a micro usb cable, so she couldn't charge it. I am pulling a consistent 22-24 hours. IDK what you guys are doing with your phones, but stop it.
I think a big issue with many people's battery life is this is their first smartphone, or first android device. You are going to use it much more than you need to... lol
Wow 36 hours that's unreal I can pull up to 16 hours Max

Are you in a 4G area? I think the 4g is what really eats us alive.
So, I was well informed from many different sources that the biggest drawback to the Thunderbolt was the horrendous battery life (people complaining in the 4 hour range). I came from a Samsung Fascinate, which would most of the time get me through the day, but just barely, and the Battery Use was almost always 70-80% screen (even at the lowest brightness). I primarily got the Thunderbolt for the possibility of 4G tethering, so the first thing I did was buy an external battery charger pack (extended battery was sold out).
Well, I've had it for a few days now and despite geeking out on the phone, tethering whenever I can, using it probably more than my Fascinate, I haven't had any issues with battery. I pulled it off charge about 8am this morning, it's currently 9:45pm, I've been using it pretty heavily all day, tethering on the train to work, using it at work, and using it the whole train ride home, and it's currently at 33% battery. 6:18:00 Awake time. Where is this horrendous battery life I heard about?
I'm not using any battery saving utilities (Juice defender etc), have it set to Auto Brightness, just letting it be on WiFi when WiFi is available. I'm using the bone stock HTC Android 2.2 that came with it, not root etc.
So far this phone has much better battery life than my Fascinate and I'm pretty impressed, especially since I believe it has a slightly smaller battery. If I check battery use today, it's 59% Display, with the next highest being 9% Cell Standby.
I haven't used it as a 4G hotspot for more than maybe 30 minutes at a time, but even then it doesn't seem to die too quickly. Am I just missing something that other people are doing that drains their batteries like crazy or is it just that I'm careful about not using stuff the indiscriminately uses 4G for no reason? (I removed all the auto updating widgets like the Friend Feed etc).
Anyone else had a similar experience?
Ummm, yah, well, it's just you...
JK... the battery is ok for me I haven't had it die on me yet but when ever I drive it goes in the charger so I'm sure that adds up.

It's you.
Seriously though. Go to any one of the Thunderbolt forums or read any Thunderbolt review and you'll see the battery being discussed prominently. There is definitely an issue with it. Who knows what it is though..
The thing that really bothers me is the battery isnt consistently bad. Like the last two days Ive gotten 24 hours of use out of my phone. Normally that's unheard of.. but next week something will happen and it will be back to being dead within 6-8 hours with barely any use.
You are correct that this issue is oft-cited in regards to the TB. However, I think the 4 hour data points may be slightly exaggerated. I wound up buying the oem extended battery because I wasn't make it past 6.5 hours with regular use. I travel pretty far to get to work every day, switching between many towers over the course of my commute, constantly going from 4g to 3g to 1x and back. Besides the screen (which will be the biggest battery drain on any phone with a modern touchscreen) data should be your next highest drain, and the biggest variable you are capable of tweaking to change your battery performance. My 6.5 hour experience was with a pretty abusive data usage scenario, and I don't see many people inflicting much more upon the battery in actual, real-world use. That said, with the extended battery, the TB has the best battery life of any phone I have owned in the last five years, and I couldn't be happier.
I'm getting about 12 hours with pretty heavy use. Running BAMF 1.6.2 with kernel overclocked. I'm pretty happy with battery life...it's just as good as it was on my droid incredible.
I have learned thru experience that all HTC phones with 4.3 inches screens are bad at battery life. When I say bad, that's comparing it to a smaller less powerful device. But take in account all it does and to me battery is ok. I mean the HD2, and EVO when I owned them were battery hogs. But I always had a charge. Ppl want bigger and faster phones,Well there's a trade off until battery technology catches up, the bigger phones will consume more battery. Its like saying I want a better car more sporty and trendy but I don't want to pay that much. Not goin to happen.
With just 3G available to me and using everything stock...I get slightly better battery life than I did with my incredible that was on CM7. Compared to a stock incredible, much better. I'm a bit scared for when I do get 4G seeing all the posts though =)
Rooting gave me an extra 2% per hour usage. I can go 15 hours and still have 40% left on my battery. I'm happy with this battery.
Thunderbolt has better battery life than my Samsung Epic had. Stock, my battery wasnt all that great. However, changing some settings and finding a suitable kernel has helped with my battery life.
I have had the same experience. Coming from a Fascinate, the Thunderbolt is so much better on battery life. Mind you, I do not live in an LTE area. This is what I do:
- Juice Defender (Balanced settings)
- Brightness - half way
- GPS only on when I need it
- Wifi on almost 100% of the time (at home and work I use only wifi)
- Non-Rooted
I even have 100+ apps installed including leaving Google Talk and Yahoo Messenger on almost 24/7. I have about 8 or 9 widgets as well. Most that pull info.
The terrible battery life comes when the phone tries to hold a bad 4g signal drains the battery at an insane amount. If you're in strong signal expect much better battery life but because 4g is so new I expect a lot of people to be in areas with low 4g signal as Verizon has not even turned up 85-90% of the towers past 45% power.
I've had the TB for 3 days now and am coming from a rooted Eris (running xtr rom). I have noticed that with the same amount of usage I am also getting better battery life on the stock TB than I did on my Eris. I am in an area that does not have 4G so I have that turned off.

I'd love to see some sources backing this info up.
When I bought my TB I left the store with the extended battery in. The battery easily lasts me all day. After reading all the complaints about how bad the stock battery is I decided to try using it and I'm actually surprised by how long it lasts. I was expecting much worse. It's easily lasted me 8-12 hours with my normal everyday use. I'm going to stick to the stock battery from now on. I was getting annoyed by the heft and bulkiness of the extended battery. My phone feels so sleek with the stock one.
Yeah, I'm with the "it's just you" crowd.
Pretty bad battery life for me here in NYC (plenty of good 4G around).
Not a heavy data user (less than 20min browsing per day).
Not a lot of long calls.
Accounts update once every hour (FB, 2 email accounts).
Brightness at min.
No video playing, no music playing.
No speakerphone used.
Rooted, BAMF 1.3.2
GPS and WiFi rarely on at all.
I'm lucky, --LUCKY--, if I get like 6 hours out of a fully charged battery.

Just curious, why are you still using BAMF 1.3.2?
running Bamf 1.6.1 and Imoseyon Lean Kernal set at 1.4Ghz with SetCPU on Smartass, along with ATK set to kill every 30 mins(oh I know they are the devil, yet my battery life is always better with one, so no comments about how they are bad.) I also always have 4G on, and usually fluctuate between -82 to -94dB in signal strength, and wifi is never on, as my home network is strained enough as it is. GPS is always off unless I need it.
I also use WPClock Live Wallpaper at the same time.
Yesterday I was at 18% with 2 days since last plugged in.
Of course I also calibrated my battery, after flashing Bamf 1.6.1.
I use my phone alot for facebook, angry birds, browsing the web and a crap ton of texting, I probably hit near 1000 text a month, I know that isn't what the high school brats are pulling, but still, for me, that is insane.
On my Evo 4G, with 4G off, I could hit 3 days running CM7 underclocked to 750Mhz max. That was with a bigger battery as well.
I am very exited for CM7 to go into a beta, or nightly stage, and the kinks worked out, as I am sure with 4G on I can hit near 3 days with the Thunderbolt as well.

running Bamf 1.6.1 and Imoysen Lean Kernal set at 1.4Ghz with SetCPU on Smartass, along with ATK set to kill every 30 mins(oh I know they are the devil, yet my battery life is always better with one, so no comments about how they are bad.) I also always have 4G on, and usually fluctuate between -82 to -94dB in signal strength, and wifi is never on, as my home network is strained enough as it is.
Yesterday I was at 18% with 2 days since last plugged in.
Of course I also calibrated my battery, after flashing Bamf 1.6.1.
I use my phone alot for facebook, angry birds, browsing the web and a crap ton of texting, I probably hit near 1000 text a month, I know that isn't what the high school brats are pulling, but still, for me, that is insane.

Update your sig, brah. Still says your running Tesla Coil.
Overall battery life is a lot better than my cm7 Incredible, and on mostly standby it lasted quite awhile before I had to charge it (I couldn't use it for a few days because vzw wonked up on activating my TB somehow), so it lasted almost 3 days with only occasional data use/seeing if the phone was working (I couldn't send texts or make/receive calls, but my data was working)

I know, I am a lazy ass, haha.
I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?
I'm running the CM7 w/the 2.5 radio - I'm in a 100% full time 4G area, but seem to have worse battery life when the 4G radio is on, so I just keep the phone on 3G - if I need the faster data I can always turn it on and off.
I'm running the stock kernal, no overclocking or setcpu type stuff going on.
Would like to hear from folks running this ROM w/killer battery life, what are your settings, tweaks, etc. Please specify if you're running an MR1 or Mr2/2.5 version and/or running the latest OTA 2 radio that just came out like yesterday.
I just turned off my FB sync (I forgot about that). I don't have gmail set up to sync automatically either.
I'm going to do this procedure a little later today and see if it helps, this is for the EVO, but, ya know....
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally.
Anybody else try this?
today will be my first full day of work use w/this ROM so we'll see what happens.
Best to keep 4g off if not using it. Also, turn Bluetooth off when not in use.

i had horrible battery life the first day - then it got better. then i flashed mr2 official and battery life is really solid. getting like 15-20 hrs with 4g always on, bluetooth on sometimes. one important thing is having a custom lighting table which i will post later.

I have never, nor do I intend to ever do this. I got an extended battery for a reason. I can go all day and then some on the official roms, and all of the Sense roms.
I am not new to CM7, I have run it on both an Eris, and an Incredible. Both devices got FAR better battery life on CM7.
I am not complaining about this rom, or Slayhers hard work. I simply want to gather information so that we may help him trouble shoot.

This is exactly what I did lol, I had lost 10% in the first 90 minutes, now I am at 58% at 5 hours. I have been streaming google music for 2 hours of that 5 though. I would guess I should have seen an increase in battery usage, but have not.
The battery readings are wrong, I get a full day on 4G with my stock battery and see those numbers for cell standby etc. I use lean kernel though
Sent from my ThunderBolt using XDA Premium App
do you see those numbers for BLUE TOOTH though? We know good and well some numbers are fake, but that does not mean all.
FYI I am now at 37% and 7 hours and 7 minutes... I have not used google music since the last post and I am seeing the exact same battery drain as when I was using it.
I have absolutely horrible battery life when I'm at work (which is basically a bunker). On a normal day, my battery will be dead within 6 hours just sitting there on my desk.
However, when I am at home (great 4G signal), I see my device getting upwards of 16 hours with moderate use.
I will also say that since I upgraded to the most recent radio, I have been having much better battery life at home. Additionally, my phone has stayed much cooler with the most recent RC + new radio combination.
I heard if you change the render fx to n1 calibrated, then you will get like 1 hour extra of battery life. You can change the render fx by going to cyanogenmod settings.
11h32m11s on extended battery 69% left
The other numbers have to be wrong. Theres no way cell standby is the number one battery user.
my cell standby is also showing 30% with the new OTA 2 radio.
I switched to dream kernel (have not wiped battery stats) and am now at 88% after two hours, that puts me at 6% per hour verses yesterdays 10.

only works for AMOLED screens.
edit: to be clear, it only saves battery on AMOLED.
so what i have found is that after installing dream kernel and messing with the governor settings... along with being connected to wifi. my battery life has improved tremendously. i wiped battery stats this morning after a full charge and didnt notice any change.. then i flashed the kernel and messed with gov. settings... after rebooting ive noticed a huge huge difference.. just my 2 cents for anyone who had battery issues like me
Yesterday I was able to choke out 20 hours while in a 4G area the entire time.
Running RC 1.2, Imoseyon's leanKernel extreme mode (extremely undervolted and OCd to 1.4GHz) and using the InteractiveX governor.
Also, I just happened to reboot and surprisingly it only took away 1% of my battery. Amazing considering whenever I did that on a Sense ROM, I'd experience a battery loss ranging from 7%-10%.

What settings did you land on as best?
cpu is set max to 368 mhz(very low) but i can crank it up if im doing somethign like playing games or downloading and want speed. brightness is at about 15-20 percent. the dream kernel and mr2.0 radio have made a big diff too. the dream kernel made the biggest. usually when id power off or reboot id lose 6-10 percent same as someone else i saw post. now i lose maybe 1 percent which is a huuuuge difference considering you lose 10 percent just because you reboot. also i try to stay on wifi wherever i go. on 3g i def notice it drain quicker, but i am no expert and there are a lot of people on here who by far outexperience and outknowledge me(my new 2 words) so im sure other people have some suggestions

That is strange I am also using CM7 with an extended battery and still have 41% left after 14:56 on battery.
battery use does show
cell standby 31%
phone idle 19%
android system 19%
wifi 11%
dialer 10%
display 6%
voice calls 3%
Just curious is it just me or does the Skyrocket have ****tier battery life running on ICS compared to it running on Gingerbread? Anyone else having battery problems. I've been running ICS on my I727r for 2 days now and the battery life is very questionable. Probably a battery stat reset will work :S

I've found my battery life better. I haven't put down my phone since, and the battery life is on par with GB with my phone in deep sleep in my pocket. Lol
I did do a battery stat wipe and drained it and recharged it to full.

Yeah, my battery went out pretty damn quick yesterday, but that could be because I've been fussing with my phone more than normal.
The first day of using ics my battery life was okay. The second day my battery life sucked. Why? Because I set up Facebook. Battery manager showed 10% use and I hadn't even checked it. Its the bloat!

Same, my i727r battery life is horrible since i flashed ICS.
I have noticed that my android system is pulling a lot of juice compared to GB. I made some changes today like freeze all the bloat + installed UCLC4 modem. And wiped battery stats + complete drain and discharge of the battery. Lets see if it get better after a few cycles.
My battery seems a lot better! Way way way better. 25 minutes of web and its still full!

Battery has been much better for me with ICS.
Freezing tons of bloat helps..
My battery life has been horrible on ICS but when I look at the battery thing, Face Unlock used 35% of my batter (when my batter was 5% left) o-o it takes THAT much?
My battery life is absolutely amazing with ICS.
I have the stock rom debloated completely, and a lot of junk is disabled. Coupled with turning off auto brightness and leaving data off when i don't use it, the battery just chugs along.
This morning I got in my car at 7 AM, started playing music full blast through the stereo for an hour. Got to class, played some temple run, approximately a half hour worth. 30 texts or so, one 1 minute phone call. (data was off the entire time, it keeps facebook from butting in from behind) My battery has literally only gone down 10%, and it's 1 PM
I'm in love.
Seems fine here, I usually have it plugged in but today am testing it without. The couple charge blips are from when I had to get some files off of it.
I froze a bunch of the AT&T bloatware, have had Wi-fi, BT, GPS enabled the entire time. Moderate/light use... I've attached some screens.
I'm running http://forum.xda-developers.com/showthread.php?t=1567817 with the flashable ICS modem.
My battery has been horrible but it's only been a day for me and my signal has been fluctuating a lot on day one. It's stabilized now so we'll see after a few days of use. But right now it is horrible.
It seems mine is doing worse.
But I have been adding a lot of stuff since this is my first time rooting.
I am about to get a battery depleted(at 12% right now) and reset the battery statistics and install the OEM battery.

I thought there was a lot of debating over deleting the battery stats, i remember an article from a google programmer saying that it actually decreases battery performance...i personally stopped doing it a year ago and noticed a better batter experience, most of the time bad battery comes from a bad flash or apps that run in the backround and use location services
My battery life was horrible with ICS so im back to GB. At work with phone in pocket for 2hrs and was already down to 75% off killing battery and charging it fully next day. When I got home after 8hrs of work already at 50% and thats when its in sleep mode. Using it I would drain 1% every couple minutes definitly bloat. Might try new debloated ones but kinda skeptical since GB gives me amazing battery life.
Once the kernel source drops custom kernels will make all you guys stop crying your all used to optimized stuff not samsucks stuff lol give it time

Well condiering I have never reset them and did this first and only flash of the ICS leak, I'm hoping it helps out. We'll see what happens.
I have Juicedefender turning everything off while sleeping(set widgetlocker to deinied so when locked, widget locker stays active to be ready, and juicedefender see's that and turns off data)
On my 2100mAh nexus battery I barely got over a day(was getting 36-40 hours on GB)
Either way, I have two batteries so I'll deal with it until either an official ICS release or a new rom with better battery performance comes around.
I also have the nexus battery. Def have less battery life with this version of ics .
It could be the algorithm the use. At the start of the day is slowly draws down. As the day goes on it seems to drain faster

Actually, I have been having the Best battery life to date. I will post my list of APK's that I removed. I don't do FB or anything like that, so not sure if that is affecting it. Also, in a non LTE area. on the UCLA3 kernel, I was absolutely getting horrid battery life.
I live in an LTE area and I am getting almost a full day of use. Never got that with GB. I keep wanting to charge it, but I dont have to.
I do have Juice Defender running though, and it disables my data in 15 or 30 min intervals when the screen is locked. And I have SetCPU which limits the CPU to a max of 384 when the screen is locked.
