cognition battery - Captivate General

so yesterday a user on this forum convinced me to finally flash my rom to cognition.
ive noticed how fast my battery has been depleting compared to the stock 2.2. is this normal?
i dont get the point in flashing a rom that is suppose to make the phone work better if it drains the battery so fast i dont even get to use it. after an hour and a half of mostly standby it is down to 85%. i am estimating that at this rate the battery will be gone in 8.5 hours.
a 10 hour battery life on full charge isn't acceptable by any means

If you are up to speed on the Cognition thread, DesignGears knows about the problem and is working on a fix. Patience, until then you can always flash back to stock if you like.

but is this common with all custom roms and was this an issue with past versions of cog?

No, not all roms are the same. This is a product of DG creating a new kernel. 4.1.1 version was very stable and gave me great battery life. You have to expect some hiccups when you adopt the newest version of any rom.

It should also be noted that sometimes when flashing a new rom, the battery calibration gets thrown out of whack. So, when you flash a new rom, always give it at least three to five full charge cycles, i.e. drain battery until dead then fully recharge, before you can make any acurate guess as to how the rom is affecting battery life. For example, when I flashed cog 4.1.1, I also flashed a new modem and kernel, and drained from 100% to dead in about 10hrs, with light usage. I am currently at 36% after 14hrs of medium to heavy usage with the same setup. I have gone through four charge cycles. So give the rom a chance, it may just be your battery calibration.

so is Gingerbread or Froyo better for battery life on the charge?

Which is better for the charge?
About same. No huge difference. I have a spare so I don't worry too much about it.

but is there any kernal out that support OC and undervolting? i cant seem to get SETCPU to work.
Technically Gingerbread manages everything better than Froyo and is better for battery life but because of all the ROM's and kernels available to us it's really a toss-up. I personally run Gummycharged Gingerbread because it is ridiculously fast, supports everything, and is great on battery. On a previous Gummycharged GB I was able to pull 2 days on a single charge with light-normal usage; like doing everything except playing games.

excellent life for me on Gummy GB, i get a full day on average depending on what I do though let me clarify a 'day' for me is about 16+ hours from when I get up till I get home and/or go to sleep... either way I think even with OC/UV on froyo I do better on GB but I always end up back on froyo for the themes lol
I've had better battery life on GB than on Froyo. It's anecdotal, but it's what I've observed. On top of that, Juice Defender works on GB, so you can make the battery that much better. With JD Ultimate with some aggressive settings and careful use, I could pull a day and a half out of the battery.

Glad to hear you make the differentiation and say JD works on GB... I run a rooted Froyo and tried JD last week. The data radio would not come back on when I brought the phone out of sleep state. Had to re-boot to get data back.

You're right that it does not work on Froyo. There's a bug tracker on the Latedroid website about it. They said last week that it would never work with Charge on Froyo due to a "terrible bug" as they put it. I've tried different combos of ROM and radio on the phone and the problem has nothing to do with the radio and everything to do with the Charge Froyo Touchwiz implementation.

You couldn't have failed anymore in this statement. For a lot of reasons. First of all, users that experience major battery issues with Gingerbread fail at flashing or calibrating the battery. Second of all, you're comparing it to a completely different phone! That isn't even a Charge! How can you even put that on our forums? Troll elsewhere.

I have tried a few EE4 & a few GB ROMs & I don't see much difference in battery life myself.
GB is certainly not WORSE than FROYO & may be slightly better. The difference is really negligible however, all ROMs get basically the same battery life - it is the kernel that can make a difference & even then it isn't all that much.
~John
And honestly it depends on your usage, if i just check for text messages once or twice an hour for the day, from 7AM - 5PM, i can have 44% Battery life left.
If i use some web browsing, and am texting every 30 mins or so, i'll be down to 20% Battery by 5PM.
If im watching youtube vids and using 4G, i'll be barely getting by at like 5% battery by 5PM.
I've tried danalo's HumbleComb ROMs, both -Froyo and -Gingerbread based. I believe he used IMoseyON's kernels on both ROMs.
I've battery tested both (battery consumption while fully configured and sitting idle - email and other minor background bandwidth consumers), and the battery drain was basically identical between the ROMs.
I saw a static drain of 2%/hour on both ROMs, which would be almost 2 days of battery life if the phone sat idle with minor background consumption.
With moderate use, I can easily make a full day on either HumbleComb ROM.
danalo's ROMs are pretty darned fast, to boot - Quadrant scores of 2040 on my HC4 GB loaded phone (Note: The Quadrant scores were faster before all my stuff was loaded on the phone).
And, danalo's HC4 GB ROM is pretty darned fast to boot, too - slightly under a minute (The -Froyo based ROMs were closer to 2 minutes).

Battery issues?

Is it normal for battery life to only get reported in increments of ten? My last Android phone would happily report 1% differences.
Also, what kind of battery life do you guys get? I'm running Hexen with wifi/EDGE on most of the time and it seems pretty poor. I'm pretty sure it's been calibrated too.
It's normal for these phones. Custom firmware sometimes solves this battery life stuff.
Since you're on AT&T, you probably use 2.4.29.
1st, on 2.4.29 you can get a pretty stable CM7 build that will display battery life in 1% decrements.
2nd, battery life on stock 2.4.x is awful. CM7 rectifies it a bit.
If you're set to use stock firmware, you'll probably want to root, and at least install SetCPU and freeze bloatware.

Thanks for the info. I'm technically on Hexen which isn't 100% stock. At the very least a lot of bloat seems to be gone. Do you know how Hexen stacks up against CM7 as far as battery life is concerned?
Actually, Battery monitor widget can display to 1%.
Im using it on Hexen rom.
Sure. It can. But it uses an estimate, not what the system actually reports.

It is pretty darn close, I'd say it reports battery percentage very accurate. Very consistent with the internal 10% gauge, no jumps and hops.

Android OS killing ICS batt life?

So, one thing I've noticed when running through the various ICS ROMs and kernels is that regardless of rom or kernel, Android OS eats up battery at an alarming rate.
In my experience, it usually is eating more power than the screen, which just aint right. Now, I know these ROMs are at an early stage, but this is a common thing between all of them. I've noticed a few others noting it, but I think most are too excited about the new OS to notice the batt life.
Has anyone narrowed down what's going on? I'm curious....
**NOTICE TO FLAMERS**: This is not a post passing judgment on ICS. I'm simply asking if anyone's figured out what the issue is currently, or if anyone has solved it.

Don't form an opinion of ICS until you actually run an official rom, and not something someone hacked together from AOSP release from a different phone, and leaked dev binaries.
I see this happen too, on the rom i am running. but won't form an opinion until there are proper roms out.
my battery life is great. I get 15+ hours on mine with no issues at all.

Jesus christ, I didnt form an opinion of ICS. You need to chill dude. Re-read my post. My post was an inquisitive one, because I recognize that it is some sort of bug or anomaly in EARLY CUSTOM BUILDS, as can be seen when I said "Has anyone narrowed down what's going on? I'm curious...."
There was no need for that....
it doesnt necessarily mean that the android os is using more battery. you can also look at it a different way.. maybe the screen is taking less battery. if the android os uses the same amount of power as always, but the screen uses less, the % battery used is going to go up for android os.
Yeah, but the likelihood of a hardware item suddenly using less power than it used to is certainly way less likely than an OS, software-level item.
I understand your theory on percentages, but as I'm sure you've noticed simms, something's draining the batt quickly, even on UV kernels, and I'm willing to bet it's OS related, and probably related to Android OS (in batt usage). I doubt this is the type of batt life we can expect with the official OTA, so I'm thinking something's running amuck.
My screen used 26%, while Android OS used 39%. In the past w/GB roms, it would have been more like screen 45%, Android OS 11-15%.

im just playing devils advocate, to try and see it from a different point of view. right now my screen is at 43% and android os is at 35%. normally my screen is around 51-57% and android os is around 7-11%. mind you, i am tethering at the moment also. but, the screen % is below what it normally is and the android os is much higher than it usually is. so something is definitely going on.
btw, in on the seuv kernel, and its doing alright on battery for me.
i am usingkoush v11 with Franco 26/11 kernel. Off charge at 9.30 am at 98%...5.30 pm 89%...very little usage today..just a couple of emails..but easily getting 15+ hours of battery life with WiFi my main usage including phone calls over WiFi.
My phone is turned on for 17 hours 38 minutes and still has 24% battery with brainmaster v5 + franco kernel
I've noticed this, too.
Last BM version drained my battery massively over night while being in flight mode.
Android OS took 87% of the battery in 8 hours.
So it's definitely a bug.
CM9 Alpha 11 is way better. In 18h 36m Android os 25%, android system 17% Display 15%.
Even though i appreciate the work the devs who are coming up with these ICS roms are doing, i can't use any of them as daily drivers (no flash/Google calender sync issues/performance is noticeably slow e.t.c). Played with Koush's version the other day and was mighty impressed, very. I'm still not sold on the whole ICS look in general, might take a while to get used to it. Seems too fluffy to me, too much eye candy. Battery life wasn't the best, but manageable.
Right now i'm on Oxygen+Carbon rom mix with Franco kernel, and OMG this combo is phenomenal regarding performance and battery life..
my battery life is the same, if not a tad better.. using kwiboos v2.

Same here. No custom kernel, no tweaks, no trickery - running Koush's V10 out of the box. Runs smooth, quick, and I go from dawn to dusk on one charge with lots of browsing, app installs, etc.

With all due respect, "Don't form an opinion of ICS until you actually run an official rom " is not a statement of fact, it is your opinion/emotional response based upon you misunderstanding of my post. I clearly acknowledged that we were working with early builds, so this is obviously not what the final product should be.
The purpose of this general forum is to have general discussions, and troubleshooting posts. I made a troubleshooting post, seeking out others experiencing the same thing, in an attempt to solve the issue, or see if the culprit has been found.
I will admit that I overreacted a bit, but I think you did the same.
I'm gonna leave it at that, otherwise this'll turn into a flame war.

I'm curious: check your batt usage. Do you see Android OS almost equal, if not higher in batt usage than the screen?
Now remember, on phones, the screen is the biggest power drain for anyone other than a light user (never turns on screen, makes 1 call a day, etc). Typically, in my usage (usually 25-30% brightness), the screen takes anywhere from 40-50% of my batt life thru the day, with Android OS way down the list. That was Gingerbread.
Android OS 38%
Display 29% (brightness at 12%)
Miren Browser 17%
Cell Standby 9%
74% remaining
8hrs 44min on battery
Sorry, my native screen cap won't save to disk, otherwise I'd upload it.

Yeah, I figured it'd be way up there. Now, I'm not saying batt life is BAD. I still can get a good 15-20h out of it if I dont use it much. But I'm used to going 24-36 hrs without having to charge, all with medium usage. I've tried various UV kernels to achieve this again, but Android OS is dominating the battery.
My battery is actually good. I am on cm9 alpha 11 on franciscofranco's kernel. It lasted more than 24 hours on medium use.
more than 24 hours is already good for a smartphone.

yep. My first impressions for it were the same, too much eye candy and too much things going on the screen. Maybe I was just used to the very simple and minimalistic UI of the stock gingerbread. But after using it for a day.I am beginning to realize how amazing and beautiful ICS is.
Yes Android OS is top for me at 45% and on GB ROM it was 4-5%. Batt life ain't too bad but I think the Android OS usage is just something that will get sorted as the development moves forward, especially after the official update drops.

Unfortunately I have been having a lot of trouble with my battery, on average my battery will last about 4 hours with minimal usage. It should last over night, but even after a 100% charge it dies by the morning. I have been on Tweak's 1.4 with PBnJ Kernal for a few weeks and I am attempting to calibrate it as I type this. Did you have to calibrate yours? And how long would your battery last if you don't mind?

I flashed Eclipse 2.0 because I can't get with the Tweakstock Theme.
But on Tweakstock 1.4 with the PBJ Kernel I had excellent battery life. I'd wake up at 5 am and listen to music for about 2 hours. Throughout the day I would check my email , the weather or text between classes. By the time track practice started at 2:30 I would have 80%+ life . Then at 5 pm until like 7pm I would listen to music and come to a battery life of 70%+ . The key is turn off data and WIFI when you don't need them . I also use ScreenFilter Pro to adjust my screen brightness because my Display is always the biggest factor in my battery drainage.

I second that, sounds like a defective battery or something like that
Tweakstock 2.0 has great battery life for me. I easily get through a full day off of one charge. And that's with playing games and using bluetooth headphones to listen to music!
I am having bad battery life also, but this is just the first day with it. I have looked at one YouTube video and within 15 minutes I have dropped 10%.

Wow! You are definitely getting the most out of your battery. I will have to look into turning my data on and off since 4G eats a lot of battery and thanks for the app suggestion. My screen also is eats up more then 60%+ of the battery usage. I am still on Tweaks 1.4, but im about to upgrade to 2.0 when i get some time.

Yeah you're completely right. As I have heard from other users on this site, the phone measures the percentage directly from the voltage on the battery. So erasing your battery stats and the excessive charging and draining is not going to help.
Been running Tweaked 2.0 for a few days with zero issues. Anything I've wanted to do as far as customizations, etc, I've been able to do either through TSM Parts or TweakTools. Awesome stuff. And battery life is as good as it was when I was running Eclipse.
Please take notes guys, I have reiterated this FAR too many times, ROMs have almost nothing to do with battery life. It's almost solely based on the kernel, if you came from a ROM with PBJ to Tweaked2.0 then you would notice a difference whether better or worse since you'd now be on a stock kernel. ROMs can impact battery life if it's an AOSP ROM but since we don't have any of those it's majorly on the kernel. Don't make ROM decisions on battery life and don't "review" ROMs based on how good the battery life is either, please and thank you

Don't make ROM decisions on battery life and don't "review" ROMs based on how good the battery life is either, please and thank you

Good point, I should have stated I was on Eclipse with PBJ kernel, now on Tweaked with stock kernel...with little to no change in battery life...meaning battery life is still good for me.

Wow! You are definitely getting the most out of your battery. I will have to look into turning my data on and off since 4G eats a lot of battery and thanks for the app suggestion. My screen also is eats up more then 60%+ of the battery usage. I am still on Tweaks 1.4, but im about to upgrade to 2.0 when i get some time. If you don't mind me asking, what else makes you choose eclipse over tweak?
My only reason for switching to Eclipse is the beautiful theme. I love the theme . Performance is great , I would like to give Tweaked 2.0 another run but I don't like the theme. I know it's a great ROM but I'm picky about interfaces.

Battery Life on Infuse: Gingerbread vs Ice Cream Sandwich

Hi, so I recently got an Infuse from someone that is still on Froyo and I figure I might as well upgrade to a custom rom.
Since I care about battery life the most, I figure I would ask which version of Android provides the best battery life for the Samsung Infuse: Gingerbread or Ice Cream Sandwich.
I probably won't be running apps that fetch/push for data a whole lot, which obviously helps the battery life. But I thought I'd ask to get someone's opinion on this specific phone and a comparison between Gingerbread vs ICS before picking a rom.
And the winner is... Gingerbread!

Gingerbread is a better battery saver. Although i get decent battery on ics and jellybean. I know i perfer all that ics/jb has to offer in features over having battery life. But for what your asking id suggest AEON or the stock gb. Aeon is very stable and has some cool extras without much battery drain

Really? I got faaar better battery life on Scott's Paranoid Android ICS build than I EVER did for any Gingerbread rom...
Honestly, I don't even remember by now
I have never payed that much attention to battery life..
usually lasts all day for me on JB, that's all I need

the more recent ics and jelly bean kernels get great battery life due to fixed bt and wifi drivers (the wifi driver and binary were taken from another device from what i understand) and more stable cpu clock code than it had initially. not too much more than stock but i have to say it is better for me. but i guess it all depends on usage. one may have better standby vs awake battery life or something. the available kernels have been this way for atleast a month. when we start to see more kernels with undervolt it should get better yet.
I'm using CM10 8/23 and my battery life is good.
One of the best I even made a snapshot (can't upload right now): 51% left after 12 hours 46 minutes.
That's why I'm in a dilemma between jelly bean and gingerbread. I do appreciate JB a lot, way better functions. But still the battery life and compatibility are big issues. I can get 2 days under gb but only less than 12 hours in JB, that's a big issue.
I have been getting great battery life with the latest JB ROMs I have been using. Pretty much on par with the GB ROMs I used.

Can't say i've had good luck with battery life, I used to average 3 hours of screen on time in Gingerbread, but since moving to ics/jb that has dropped to anywhere from 30 mins (if i leave the phone and standby drain eats it) to 1 hour 45 mins on a single charge...not good.
No rogue apps, no media scanner (i constantly check these things with betterbatterystats, i don't install anything i didn't install on gingerbread). Just the cell phone standby drain eating my battery alive (BBS reports it as GTALK_ASYNC and RILJ wakelocks).
I've been researching it for months now and get various answers (the wakelocks are caused by bad APN settings for example), tried all the fixes, still no luck. I suspect that it's probably a Rogers thing but who knows.

did you try cm9?

Yup, it's all been the same since ICS, I absolutely cannot get acceptable battery life, no matter what i do.

are you getting AOS drain while on wifi?
you may consider a factory reset and sdcard format
when you reinstall, decline all google locations and backup services.

I have done a factory reset, i formatted my sd card not too long ago (I also suspected this)
I also make sure google locations is disabled, never keep backup enabled (i did once by mistake and the auto restore nearly killed all my monthly data)
I am going to toggle wifi tonight and set a marker in BBS, i'll check the drain overnight (I did this a while ago and it did improve standby drain somewhat, but I am going to try it again)

i do notice battery drain in some areas. but not others. some people seem to think certain modems are effecting the cell standby drain, not sure myself. but there are many compatible modem.bins to try from att and t-mobile(t959v)
Just an update: wifi didn't help much.

I've been playing around a bit with different gb kernels, odex and deodex.
I found the drain issue much less on stock uclb3 kernel and rfs file system.
Almost all drain were associated with being on wifi...wakelocks and something else kills the battery.
If I have wifi off, there is usually not any issue.
You may have to play around a bit to see. My experience on cm9 and cm10 has been limited. I have noted several users noticing drain on cm9 and cm10 as well.
To avoid drain:
1. Use it to the max and constantly.
2. Leave the phone on airplane mode when not in use.
3. Turn off data (wifi and mobile data) and background data when not in use. I use this last mode.
Thanks for the tips man :good:
Airplane mode of course makes batt life better (disabling data doesn't), but when I start having to make sacrifices I didn't have to on GB it becomes a problem for me. Why should I jump through hoops and gimp my convenience for battery life that still isn't even as good as GB?
Instead of that i'd rather try to find the root cause of the problem. Doing so then allows us to help others that may have the same problem.
It definitely is an issue with the radio (or rather CM code overlooking something concerning the radio). What exactly, i'm not too sure. I've tried different modems as well, UCLB3 on JB was awful for battery life, UCKL2 and UXKG3 are slightly better but still not that great.
I don't want to complain about these things, I always try to research first, but damn....i'm stumped.

Yeah, I agree with you there. The techniques I use is pretty simple. Pose the hypothesis. Start with a full deck and slowly eliminate or start minimal and add.
ex: flash jb without gapps; without microSd. try different modem; try a different kernel. different kernel from different build.
have to use it for a few days to find out.
do the same for cm9.
add gapps...
add microsd
etc..
at some point, you will find out contributing factors.
There are a few battery thread that may be helpful if you havent looked:

This is true, and you can save battery life w/ customization and now Scott is up to JB being one of the best battery life roms I've run
or just turn down your screen brightness
