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.

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.
There are a lot of battery threads out there, but i wanted to try something new. I want to see how much our phones drain in real world situations. So here are the rules:
1. Use your phone normally for ten minutes.
2. Note your battery percent at the beginning and then at the end.
3. Post details about what you did, what ROM you're using, and the percent battery drain.
Hopefully we can compare our experiences and learn something.
I used my phone to surf a few websites, send one text, and use xda app. Started at 80% and ended at 77%. Using rcmix3d at 50% brightness.
I know there are tons of factors that affect battery drain, and I'm not trying to be scientific. I'm just curious how we all compare!

The only way you will get a decent idea is to test with others in your area as it will depend alot in signal strength. I would use more battery if I was bouncing between signals instead of having a steady connection.

Screen-on time is the only thing I ever look at. I've only managed to squeeze about 5h45m, out the sense-based gb ROM I've been using.
The phone does really well in standby on most if not all roms that have been flashed properly, don't have non-rom-related battery hogging app issues, and, as zelendel mentioned, signal issues.
It's this big fat screen that's obviously the biggest battery sucker.

My phone does great in standby as well, but seems to die quick when I'm actually using it. I've never had an issue with the phone dying on me though as I recharge every night. I think i had a little better battery life on miui than I'm getting now.
I know there are many many factors that go into battery performance, I'm just curious what other people actually get when using their phones.

I've gotten accustomed to putting my phone on the charger before bed as well. Mine pretty much will last the entire day... Off charger at ~8-9am, back on it at ~12am.
Averaging about 5 hrs screen on time with usually no voice calls of significant length, WiFi on, gps off, relatively stable signal.
I'm running Inspired Ace 1.0.1, and the 04.11_M2 radio. Seems I was getting a little better with the OTA radio, but signal fluctuated a lot more on that one, than with the 04.11_M2.
Edit: doesn't really use your testing procedure, just more of a general feeling, as there's so many other contributing factors...
10 minutes of on-line gaming (storm8 games) = 10% drain
WiFi off, gps off, mobile data on, screen brightness on auto, stock rom

Holly crap that's a heavy drain. I couldn't possibly use this phone with that type.of battery drain. Thanks to our great dews I managed a little over 7h screen on time. Could only accomplish that by reducing the screen brightness and UC to 768mhz. Stick speed and auto brightness I get about 6-6 1/2 screen on.

My battery will drain about 5% if I even just leave it sitting for ten minutes... I JUST rooted my Inspire and flashed the RCMix3D ROM, and it almost seems worse. Have background data, auto sync, wifi, gps, bluetooth, all that stuff shut off, too. I love this rom, but really want to find one that improves battery life!

You probably got a bad flash, or have something else running, as I mentioned in your recent thread.
Did you full wipe prior to flashing?
Try out gingerbeast, if you still have battery issues with that, after properly wiping prior to flashing of course, then it's hardware, as that ROM has produced some record-breaking battery life performance.
Mine has twice decided to randomly have days where it just drains like crazy. The battery is a lot warmer and just dies out in like 6 hours with very minimal usage. the majority of the time my battery is great but the last 2 days and then about a month ago it did this. No reason for it either, I have made no changes on my device.
Anybody seen this?

Yeah I did a full wipe before flashing. I'll be sure and try that out tomorrow, I really hope it helps. If the issue is hardware, should I contact HTC? After I believe you said my phone should still be under warranty, I called them, and indeed it is. The rep I had before must have been new or something. Thanks
From a full charge, on TPGB with wifi, gps, and sync on, and everything refreshed 3-4hrs, I lasted about 8 hours. I was using super accurate gps for 20 minute intervals or so, but it lasted the day I'd say. Some occasional web browsing.
Lucky for me my head unit on my car has a usb port. For this whole trip I left it off though.
I've tried them all, well, I did about a month ago. I can't get more than 5 - 6 hours of battery life. Went back to GB ROM and I'm up at 11 - 12 hours.
FWIW, been flashing ROMS since the original G1 so I'm not a n00b. Thanks!

I tried Sky ICS 4.2D-9, and battery life was decent. The best results I got from GB, I was also able to get on ICS. However, I was able to reach those results w/ GB more consistently. I was using NexusMod4 and now on 4.3.
I have the latest leak and I get much better battery life than the first two, but still not as good as gb.

it really depends on what apps u have installed, if they used data or not.
ive been through alot of phones, and never had a phone that I can use the net, and apps, and all that, and expect good battery life. if i let me phone sit and not talk or anything, yea i can get 2 days out of the battery lol.
The way i use my skyrocket, i get about 8 hours. By the time i get home from work in the afternoon, i throw it on the charger. and it get charged when i go to bed, no matter how much battery it has left.
Just buy the biggest battery you can find. lol and buy 2. batterys are cheap.
I use my phone before bed and sleep from 10 to 7 with it unplugged and next to me and barely kill my battery. I'm on pure CM9 though. Not one of the builds that are on here yet though. Can easily have it last for a whole 24 hours.

Yes the new release (ucle) is definetly the fastest and least buggy of the prior releases; on mohans embryo 3.0 I get all day battery life I strongly recommend his and Sean's new ucle rom I like mohans a bit more but try it out man this rom is comparable to mods nexus gb mod rom in speed reliability and battery life
I get absolutely terrible battery life with both the cm9 nightlies and AOKP. It drops about once every 30 seconds with my screen on...sad part is this is my 3rd battery replacement and my warranty expired like a month after I got the phone. So I'm stuck. Any battery tips for cm9?

I've tested most of the ICS ROM's and Sky ICS was the best battery by a noticeable margin - even better than stock GB.
Juice Defender is genius, it'll double most any ROM's battery life by disabling the data radio's while your screen is off... Great App, highly recommended.
Battery life is always going to be hit-or-miss; as a user you have to find the best ROM for your phone, and yours alone. You're going to see a couple people post battery lives that look ridiculous and you'll get a terrible pang of jealousy, but in the end their usage circumstances are likely wildly different from yours and you'll never be able to replicate what they've done exactly.
I found that I got better battery life with CM9 than SkyICS, even though seanz' ROM absolutely was smooth and reliable. In a situation where I was on LTE all day and had no wifi available with minimal, sporadic use CM9 used less juice than SkyICS...for my phone.
JuiceDefender is a great app if you don't mind going back to the Windows Mobile method of polling for updates instead of push notifications. I can't stand feeling like my device is a brick except once every thirty minutes or so. I find that for my usage my battery works perfectly well for what I need operating with all cylinders firing.
I just got over 24 hours with more than 30% battery left on CM9, 1h20 screen on, probably 30 minutes of talk time, Wifi on at all times. There is a great post on power saving tips, I can't find it but the tips are below. I've done most of them (4,5,6,7,8) and it's definitely helped. The other thing is that I found out by using CPU Spy and Better Battery Stats that after a full charge overnight, even though the phone was off the charger, it would never go into deep sleep because there was a kernel wake lock on the charger process. A reboot would clear it, and since then the power savings have been dramatic since it goes to deep sleep about 90% of them time. Might want to check that out as well.
1) Droidwall, without question my most useful app. Only applications that I WANT to connect to Internet can. It takes some configuring, but is well worth it.
2) I don't have any automatic email sync, which some of u may, so this probably helps. I just manually sync when I want to, no time sensitive emails for me.
3) Likewise with point 2, i have no active sync of any app really, including Google Talk, or Google+.
4) My favourite power saving app, Lux Auto Brightness. It allows you to custom set brightness levels in various lighting. It again, takes a bit of initial setup, but is worth gold when it's done. I have it set to adjust on phone wake.
5) Goes without question I'm using the ucle2 modem, best ics modem the skyrocket has at this time, for at & t and rogers
6) Under settings > performance, I've underclocked to 192 min and 1188 max, with on demand. I've noticed no performance hit, and it sticks after boot, even though if u got back into the menu the values seem to have reset. I check with cpuspy.
7) Disable surface dithering and enable 16bit transparency, that seems to have increased smoothness without sacrificing display quality.
8) Obvious one, under settings > developer, mke sure force gpu rendering is set to enable, and both Windows and Transition animation scale values are set to 0.5.

Doesn't droidwall only work with a custom kernel that supports iptables?
I'm pretty sure using it without a custom kernel would only be a placebo
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

I have never payed that much attention to battery life..
usually lasts all day for me on JB, that's all I need
Sent from my sweet & buttery Infuse
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.

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)

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.

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:

Really? I got faaar better battery life on Scott's Paranoid Android ICS build than I EVER did for any Gingerbread rom...

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
Hey how does this look for battery life guys? Any tips to make it better?
Btw, I get no signal inside school so 7 hours of that was little/no signal.

Since you know you don't get a signal inside your school, you might as well turn off mobile data or even just airplane mode it while you're in there.
I agree, turn off the radio so you don't waste the battery. Maybe you can use something like Tasker to do it for you only when in class.

Tasker is very difficult to use. I have tried and failed. haha. but i found an app called autopilot that will basically do the same thing youre looking for. it will check for signal strength and enable airplane mode if its low. then recheck in intervals to see if it should turn airplane mode off.
Yeah. Idk why I dont already do that. Lol. But I do seem to get a little bit worse battery when using it. Not too bad but not like before

Just turn off data in school. You'll still be able to receive calls and texts without data. I'm using the Synergy JB R106 build and I'm getting decent battery life.

The cell standby is calculated incorrectly so don't worry about that. It's not really using up any battery.
For the exception where it's trying to locate the towers.
Anyways, i'm on CM10 latest night build and i'm getting awesome battery life, along with the VRL15 radio and RPM
I have "my profiles lite" it lets you set times you can have the airplane mode activate so if you have brakes at certain times it will come on at that time
I have used the app called NoBars, which puts the phone in airplane mode when it loses signal for a set amount of time. It then retries after another set amount of time. Sure, you don't restore the connection immediately after getting back to a signal, but it works pretty well overall.

How's the synergy rom treating you in comparison to CleanRom 4.0?

Jellybean ROMs have all been worse on the battery life IME, so I am interested in seeing what the official JB stock will do. I have heard that part of project butter for Jellybean was to ramp the CPU to max upon touch interaction which could be a clue as to why it is worse.

leak has a wakelock issue.. hopefully the next leak or ota will fix it.. but i still like me some jbtw lol
i dont understand how people get days on end with the stock battery......I end up using about 25-30% every hour i'm using it with various battery hungry processes disabled. Now I'm using an extended 4500 mah battery that I hate because it ruins the cosmetic appeal of the phone by making it look fat and heavy. I feel theres something I'm missing in all of this.......
I am not rooted before anyone asks what programs I use.

its easy to manipulate your battery screen to be on for many hours.
your screen on time is a better indicator of how your battery is performing.
all is dependent on settings o course though.
ya went back to synergy ics rom and its night and day my battery last forever on this ics rom with lean kernel at 1.7ghz compared to stock speeds on jb and this ics rom is SO smooth has google now so im not to worried about jb till they get battery life straightened out.
Loving CR4 and the battery.
It was asked how the battery is on CleanRom4... it's doing great! I don't have specific but let me say I use my phone all day for surfing XDA forums as well as standard apps/mms. Talk about 2 hours total daily for work. Even throw in some Netflix and I don't charge it except for every other day.
I would say that's great battery life.
:good:
Battery life is normally different from each person but similar results may happen

I'm on Synergy r111 and I get great battery life, 5 hrs average on screen time with brightness at 50% n newest radio n rpm. Before only used to average around 3 hrs. I even managed to get 6.5 hrs at one point.

On I5 my battery life was 15hrs with 3hrs screen on. On J1 im at 20hrs, 2hrs screen on, 44% to go...both setup the exact same.
I've been satisfied with battery life on cleanrom le 3.5 thus far. I'm not a heavy user but I'll get 3 hours screen time easily. Tried going back to ICS after jb and I can't lol
