I've been running this ROM for some time now, and am noticing about a 10% drain per 24hrs, and that's with 97% "deep sleep" according to CPUSPY. And CPU performance profile set on hotplug (not using SETcpu).
Anyone have any ideas on how to improve? I was running a CM7 Beta prior, and battery stamina was incredible, I could go for 2 weeks with moderate use on a single charge, this drain just seems to be a bit excessive.
it is commonly known that so far...cm10 has terrible battery life (it is a bug in the original cm10). NOT FIXED yet
I dunno cm10 used to drain about 10pct an hour even when wifi was off and screen off. Now it's 1-2pct a day that I've noticed its been solid for me. 10pct, a day doesn't sound too bad considering what it used to be

Using the app "Battery Monitor Widget" I have determined the following....
My Droid X sleeps at -5 mA while sleeping.
My T-Bolt sleeps at -48 mA or more (usually much more) while sleeping.
Both phones run Gingerbread.
Both phones have the same apps, running.
Why does the T-Bolt draw so much more mA's?
I've turned off the 4G radio and it didn't help.
Any other ideas?
Thanks.
Your T-Bolt is not alone, mine runs in the -40's too. Recently into the high -30's with some undervolting. What rom and kernel are you using? I am on CM7.
GingerBamf Remix with Imoseyon 2.5.3test7 running Extreme and Interactive.
i have very bad standbye life on mine running BAMF froyo versions too. I really want to know what is causing the horrible drain. Nothing really shows up as keeping the phone awake or anything.
I noticed this the other night. I went to sleep around 3:30am (...after tending to crying daughter) at about 50% battery and woke up at 7am to a dead TB. Plugged TB and checked System Panel app and saw my battery drain in about 2 hours with no device usage at that time span but 10% cpu activity while in sleep mode. I have been keeping WiFi on at the house lately which has helped on battery life when connected but have also noticed my TB having a hard time connecting to Wifi when I get back home or waking out of sleep mode. Does Wifi connection cycle in sleep mode if it is having a hard time connecting? Also had two reboots for no reason the last few days as well. I love this TB but these little annoyances are.....well annoying!
Every time I root, I end up going back to stock. To me, it seems to runs smoother and with better battery life than any Rom and kernel mix I've tried.
My phone lasts me all day with some texting, web surfing, playing music, a few calls, some tethering, and some YouTube. When I plug my phone in at night I'm usually down to 40% give or take.
I also use green power to manage my data and WiFi. It works great.
Over night I might loose 1% but thats it.
Just my opinion.

Hey guys what's a good app that you use to track that information for your battery discharge rate?
Nvm lol just reread your post. Thanks.
SETCPU
Im assuming your rooted if so install SETCPU and in Profiles you can turn the voltage all the way down on the "Screen Off" option but make sure you check the ENABLE box and after you wake the phone up if it seems to be a little choppy just go back to SETCPU and check the ENABLE box again which will disable it, works for me
I am running stock Rom with basic tweaks (display, background data) and just uninstalled the task manager I was using and improved my battery life by 30%. I now go almost all day with moderate use with out having to recharge.

Oh yeah. Task managers are bad news bears for Android phones.

Let me just clarify that my battery life is fine. I only lose a few % overnight. I was just confirming to the op that -40's is normal.
I have (finally) just made the jump to CM7 and have been absolutely loving it (MAJOR props to the Devs for it).
Anyways, one thing I have noticed is that the battery drain when the screen is on 'feels' like it is faster than it used to be on deblurred roms.
I am running Faux's 1.3 ghz overclock kernel (.2.1) and have it moderately undervolted (as I am still getting a feel for undervolting in CM7).
On my previous rom, Alen v4, I was running the same version of Faux's kernel (obviously not the cm-specific one), and was undervolting as well (though to a lesser degree, as it seems that CM7 is better for undervolting). I never timed the drain on this rom, but I could have sworn that I got an hour of screen time for every 10-12% of the battery.
Anyways, the battery seems to be draining at about 1% for every 3-4 minutes (average time over a 10% period was 3 minutes, 40 seconds per percent) of screen-on time when I am only using it lightly (I was reading the news and browsing Facebook a bit during this time).
My drain when idle seems very reasonable.
Does this seem abnormal, or am I just being overly paranoid about battery life?
In practice, I think this is still going to be fine, as I never have the screen on for more than two or three hours in any given day...I am just curious as to how the drain I am experiencing relates to anyone else's.
Thanks!
(and yes, my battery is fairly well calibrated. Was 'fully charged' this morning at 99% at 4169 mv...not perfect, but still solid).
Edit: And yes, I know I am breaking xploited's fifth rule of battery life...
The only thing I can think of is that you are overclocked all the time.. or have something running in the back ground all the time.

I've been using the latest gingerbread builds and I'm having great battery life, But I notice when I use AOKP or any kind of ICS rom my battery life isnt so great..
Is there a specific kernel you people are using? and What kernel settings are working the best for you?
Thanks!

Good news that you are not alone. Based on my premature calculation, only 10 out of 100 (that's 10% ) ICS ROM users have good - great battery life, meaning the rest is having worse. Mine is falling into that group. I never have great battery, only so-so and below average.
Also as Nick has mentioned, asking for which best is a NO NO here.
One might be good for me, doesn't mean it will be good for you and vice versa.
Try them all and pick one that best suite for you.
My 2 cents......I know you have read this several times - but battery life is really dependent on a lot of factors - your AT&T signal, rogue apps, data sync frequency, CPU governor etc. etc.
read Entropy's excelled thread on battery drain on this forum.
i tried out a few GB roms over the last few weeks and really did not notice any battery improvement over ICS.
Currently running cMIUI with xxkernel and it is really working out great as in the battery easily lasts for the whole day.
I remember when I was on stock GB I could go upto 2 days on single charge - but that may be due to the battery being brand new. I have read that the battery in SGS2 really degrades fast
I have 2% drain per hour when doing absolutely nothing, screen off, wifi off, gps off during 8 hours overnite.
While someone has reported having only 2% or 3% drain over 8 hours overnite.

Have you tried using "Better Batter Stats" to see what is causing the drain?
I have been using AOKP since Task brought it to us and I average 1% every two hours over nite.
Do you use the Facebook app? That sucker is hungry for your juice.

I got BBS v1.7 for a while, that was absolutely no help.
I installed BBS 1.8 for about a week. Based on their info, I got the "multipdp" along with some other things (such wake-lock) cranked up big time.
I read the Entropy thread, not much help.
Note: Wifi is off.
Maybe 3G/H+ keep toggling for sync process?
I do use facebook! haha. and I havent used better battery stats

I'd also recommend using CPU Spy in conjunction with Better Battery Stats to see if the phone is able to enter deep sleep.
I don't get as good as you. . .I average about 1% or less per hour overnight. But that's with wifi on, periodic syncing of 7 accounts, scheduled backups and cache cleaning going on.

My understanding is multipdp will show when apps are waking the radio to use cell data - each wake instance results in a minimum of 6 seconds of wakelock. Switching to wifi when you are idle "should" eliminate this wakelock.
I could be wrong here...dig into the known battery drainers thread from around the time the first ICS roms were being tried on the i777. There was some discussion of it...it is a renamed version of some other wakelock in GB.

That's what I said, "maybe 3G/H+ toggling".
I believed that if I left wifi on overnite, do nothing, I still had 2% drain per hour.
Let me completely turn off data tonite and see how thing goes.
errrrr I have a huge problem with my battery. I've been testing various ICS roms and kernels(aokp, foxhound, serendipidity, fluxxi Kernel, siyah 3.4.3.,Neak) and all of them with the exception of serendipity w/siyah kernel, drain my battery real fast.
Not really sure what the problem is but when I look at what's been using the battery its most of the time either screen (which is understandable) and android os? I went to bed last night leaving my phone at 100% and woke up to find it at 52%. When I looked at what was using the battery it displayed, 93% android os and only 3% cell standby??(btw Foxhound ICS, Siyah Kernel) Maybe I have to many things updating/syncing?
When I first got my phone, 2-3% battery drain overnight was one of the things that amazed me about stock gingerbread on the i777.
I've flashed alot of roms since then, and so far, no ROM can even touch that stat.
Recently had some issues with battery life so went out and did some research asked some questions and i'm quite happy with the result.
Started at 95% Battery
Down to 10%
16h 17m 50s on battery
Screen time on: 3h 46m 49s
Wi-Fi been on for about half of that
Used Chrome to browse the web
Played some Angry Birds
Played some Bad Pigs
Checked Facebook/Twitter
Could improve this more i guess as i'm currently not running full battery profiles on Siyah but quite please. Just wanted to compare to others and see if its any good or not.
On a side note my mother in-law came round today check her stats 1d 12h on her phone and still had 40% battery on stock ICS lol but she only uses it to text/call.
I'm running omega Rom v29 with phenomenal medium kernel and powwersave mode on. I've Been using my phone most of day for calls light browsing and xda I'm currently sitting at 52 percent with 13h since last charge

to achieve insane battery life. useany JB based Samsung ROM. Freeze anything you dont use via TB. Then Flash latest perseus Kernal. set your phone to power saving mode. there no lag on power saving mode with his kernel. finally,drain your battery completely. turn it on, charge to 100. then turn off the phone, keep chARging to full. and use it for couple days, then report back

Hi, guys. At the moment I am using Johnny's CM10.1 ROM and everything works as it should, however, the battery life is relatively poor. The phone does go in deep sleep mode after the screen is off, but IMO deep sleep is not very efficient. I lose about 15% battery juice over night although CPUSpy does not record any CPU activity other than deep sleeping. Also, the phone is always a little bit hotter than normal. This problem should be kernel-related as it is not present when using a different one, such as Anryl's. Does anyone else have this same problem and if you do, how did you get past it? Please post your experience here as I've already mentioned this in the official thread and got no response whatsoever.
If you have FB installed it will eat up your battery, use the android sdk to monitor cpu usage.

Like I said before.. 4.1/2/3 eats a lot of battery.. Try 4.4. .. I have 70 percents right now and the phone is 12 hours on the battery
