Okay so I have always had bad battery, but this is a bit extreme.. I am using Suckerpunch build 40 and Serendipity and i am heavily undervolted. I got about 6 hours of moderate usage out of it today before it died. (some gps usage, browsing xda, 40 texts back and forth, internet browsing) I am using JK3 modem with HSUPA enabled.. but i feel like this battery drain is a bit excessive. Any ideas?
If it isn't an app that is polling too much or it isn't a low signal issue, then I could only blame the hardware for being defective. That combination, even with the 1400 overclock has yielded me easily over 24 hours with moderate usage. Even now, I have gone 6 hours with 80% remaining.
Okay, it's caused by one of three things as I see it. And I bet your issue is the 3rd reason.
1) Bad battery, get a new one, but probably not the issue
2) Applications going out over the network a lot, especially if you are usually in the worst area, where you barely get reception, but get a slight amount... this one is tricky because I am yet to find an application to map out how much network an individual application uses over time. Some will monitor which ones are going on the network and some will monitor total network, but not break it down over time per application.
3) A background system application, or user one, is using more CPU than it should and sucking your battery. I had this issue, and at it's worst I was getting only 2 hours of battery life. I finally realized my phone was running hot for no reason. Because of this observation, I got the best application I've found on the marketplace for this, SystemPanel (The paid version). I hate buying applications, but this one saved me money from getting a new battery/phone. System panel will monitor your phone for a given period of time and break down the top apps by CPU useage over the last so many hours (you choose). What I found was that a system process (kswapd0) was sucking 24% CPU. This doesn't mean it accounted for 24% of the application total useage, it means it account for 24% of the CPU useage, which is different because if total application useage is only 1% then 24% of 1% isn't bad. But, 24% of the CPU is. So, I reflashed and all problems were fixed. Battery life could go 36 hours or longer with little useage and ksawpd0 was down to around 1.4%. Later I had bad battery symptoms again, but not as bad (like yours 6 hours and dead), and I checked SystemPanel and guess what, kswapd0 was accounting for 6%. I had to flash again. It's fixed again, not sure why kswapd0 does this, but
What I guess I'm trying to say is get SystemPanel and find out why your battery is dying. It also graph's the phone's drain. Look at the slope of that graph and see if it's extreme. Time when you are using it for internet should be really bad, but the idle time shouldn't be. I get around 36 hours idle time like I said, and if I were to just play robodefense or use the internet non stop I'd probably only get 2 hours of constant useage.
You might have wifi enabled all the time? If you have wifi on when your not connected to a wifi network it drains your battery like no tomorrow.

Seems like the system process idea might be my problem, because i know that wifi is not on, i usually disable it or juicedefender does it for me. I'll go through my normal day of light usage and then post a picture of my battery snap graph. If it isn't better by a run through again today then i will probably reflash like you suggested.
Calibrate.. Charge up to full.. Boot recovery delete bat stat.. Unplug ...discharge.. While off charge up to 100 ..then use

Poor signal is another culprit, especially when using non-captivate modems.... this will cause rapid battery drain. I had one location where my phone would only last 8 hours with no use, because of signal.

Let me know your results!
Try changing the ROM/Kernel combo. All kernels don't go good on all hardwares.
Yes I'm also eager to know what you find, as I am on the latest Phoenix with Firebird 0.8 and JL3 or 4 not sure which.. My battery life just plain sucks, will be getting that app now to monitor.. Anyway let us know what you find asap!
By chance have you tried a different battery. If memory serves me correct, some captivates were shipped wit a bad battery, and they were being replaced under warranty. Just another troubleshooting step.

I'm also experiencing some bad drain on suckerpunch #40 with di1igaf's stripped 5.6 rom.
after flashing, restoring all my apps, syncing my google account, and setting an undervolt, I let my phone idle for 2 hours. over those 2 hours I lost only 1% of battery- I was so excited! this was the best battery performance I'd ever had.
then, I left the phone unplugged overnight and I lost over 20% in 8 hours. I have no idea what happened!
I have been using watchdog lite to monitor processes- the only thing that is using up any CPU is "android system" which is usually taking up about 10% of my total cpu- does that sound normal?
I thought this might be a problem with the flash so I re-flashed but the issue persists. I have been using the same app/widget setup for a few months now with several different ROM/kernel combos and have never experienced this kind of battery drain. Not really sure what to do at this point...
(edit- I have wifi set to sleep with the screen off so this shouldn't be the issue and I flashed from 100% battery and cleared the battery stats)

I had the same issue with that kernel. All kernels may not go well with all hardware. U cud try the kernel I have in my signature. A couple more folks tried the same, and are happy with battery. Idle drain (overnight, with wifi turned off) is about 4% per 7-8 hours of sleep time. ROMs too are known to drain, but in this case, I would strongly recommend trying out kernels.
After battery calibration, I would strongly recommend atleast 2-3 full charge cycles becoming coming to a conclusion that battery drain is high.
thanks for the advice. i will go through another 2 or 3 cycles, then I think I will try the speedmod kernel as I have had success with that in the past. if i'm still having issues I will definitely give that new xcal kernel a try.
the weird thing is the drain seems to be going up and down. right after I flashed, I was losing about 1% per 2 hours. then overnight it was over 3% per hour. this morning it was more like 1% per hour, but now it is speeding up again.

Speedmod didn't go well with my hardware. I have more drain using speedmod than I have on xcal.

I've tried everything: JK3, ZNKP1, JK4, JL2, JL3.... znkp1 gave me the worst battery honestly, JK3, JK4 or JL2 were the best.
I think I'm going to accept my less than a days worth of battery and carry around a spare with me. Any way here's my usage yesterday. some light usage in the morning (pre 720 am) with idle the rest of the day until 210 pm
Ok i found out my battery stats are resetting at least every boot. Would this be detrimental to battery life?

For good battery life, I recommend using Precsion Rom 1.01 with Speedmod' kernel. I am getting amazing battery life with it After 2d 5h 10m 25s, I am still at 27% battery life.
My battery seems to be REALLY bad. Worse than most peoples from what i gather from reading threads. I get about 8 hours from a full charge with minimal use. It seems that my screen is taking up most of the battery, according to my battery use page.... Any one else having major battery drain like I am??

My display is taking a huge percentage as well. Everything else is low percentages. Don't know why. My screen is always either on auto brightness or completely dim.

Peeps, you missed most important thing. Look at the AWAKE line. Either OP is playing a lot with th phone, or something is not letting it sleep.
Yeah, the battery really plummets when you actually use the phone (even on low brightness) but it idles quite efficiently at least...
Did u try juice defender? Just asking ify bout the sensation dnt knw either to get it or wait for sumthing else

Yeah, noticed same thing
I downloaded juice defender beta? whatever the free one was. To me that app does not have a good layout at all, either that or I was missing something. There dont seem to be any personalization settings at all. I dont trust apps to work when they just say "im doing something!!" ya know?
Now that I think about it on that charge I was playing music while I worked on my car for a while, that would explain the awake time. Even without doing that battery life is still really bad and the screen takes up 80%+. I will post another pic after my battery dies today. Dont plan on using it much so hopefully it will last longer.
That is good news about life getting better after a week or two though cause 8 hours with moderate use is unacceptable. My MT4G got a good 24 hours with pretty heavy use, I expect this thing to get at least half that.
i use juice defender and under normal use and a few hours of pandora streaming on wifi im at 35 hours at 40% battery
My phone was also drained like madness, within 6 hours it was empty, even if I didn't do anything with it. At the moment it is better, I did a factory reset through the startup of the phone (turn phone off, remove batt, place batt, hold volume down and push on/off button). There is an option to factory reset.
Strange thing was that when I turned off my phone before the factory reset, it was telling 34% batt. Right after the factory reset is was at 89% ???
I use Battery Status Bar app to display my batt in percentage...
But the good news is, my problem is now solved. Battery lasts for more than a day at normal use and 6-8 hours while very actively handeling it.
Looks like it was a reading wrong information or something...
Got 11 hours out of a battery today. So far its been charging for 4.5 hours and is at 94% charge. Takes about half as long to charge it as it does to kill it!
I will give juice defender a try. Seems like it works for a lot of people.

I had same kind of long charging last night. Battery died at about 7:30pm. I plugged it and did not turn the power on. Went to play some ice hockey and after that I turned the power on again at about 10:10pm and it was still charging. At about 11:20pm(still charging) I unplugged for a couple of seconds to see the specs of the charger and then plugged back, surprisingly percentage jumped to 100. It was still on 100 this morning at about 8:00am.
Now I found out that phones own battery monitor tells me that time on battery is roughly 8 hours But when I check the time from Battery Indicator it tells me that time on battery is roughly 15 hours, which is correct.
Seems that a lot of people are getting false battery readings, me included. I did a factory reset last night and this seemed to fix this, at least until now it seems to report correct (realistic) values. I haven't charged the battery after the reset so we will see if charging messes it up again...
I hope this is a software problem, i really don't want to exchange my phone, i don't have any of the other problems.
what sort of battery times are acceptable for this phone? many are suggesting factory resets and all i wonder if i should do it or not. if i charge the phone overnight it goes to power saver mode usually say 8-9pm and then the power saver mode (basically dim screen and no gps wifi remains on) is managing to hold the power till i go to bed and charge it. is this ok?
juice defender seems to be recommended eh? maybe one should should try that before the factory reset. btw if factory reset done whats the best way to restore your phones contacts to how they are now? i mean it took forever to link all the facebook, phone and microsoft exchange contacts and offcourse gmails. dont want to go through that again.
I tried juice defender last night and it didnt seem to help. I lost 45% overnight without me even using the phone! When I fell asleep the battery meter said 100% still and I woke up to 55%. The phone says there is some awake time, wonder what it could be? As much as I dont want to do it I think a factory restore may be an option since nothing else is really helping. Should I wait until the battery is 100% before I reset it?
Some new pics, keep in mind I was asleep for all of this use except for what the screen awake time says.

I would say you battery life isnt that bad, if it lasts a day then it sounds about right. People are saying the batteries last longer after a couple weeks or so. If you do factory reset try and connect to wifi when google is restoring your contacts and such, it makes things go a lot faster.
I managed just over 9 hours on my first charged but I'm recharging it now and it went straight up to 31% when it booted up again :S
Me and my gf both have a Sensation now(i upgraded from HTC Desire, and she a HTC Legend), we are both pleased with the battery on the phones, she uses stock Sense, and i use LauncherPro, though we did learn something from our older phones, the thing that drains battery extremely much is all the notification emails Facebook automatically send(gmail push), these are almost turned off to 100%, next thing is to turn off all syncronisation in the phone you don't use, ex. i use Launcherpro therefore i don't need the phone to update Sense's own weather, and so on.
We both normally charge the phone every night, but i guess my phone would last almost 2 days on days i don't use it that much.
I must say i am extremely satisfied with my phone, the thing that i dislike the most is the camera, or to say it in a different way, if i didn't know the SG2 had a slightly better camera i may have been more satisfied

You should not have anywhere near 100% awake time unless you're using the phone at all times. You have some app that is not shutting down or auto-updating far too often. That's your culprit - find it and your battery life will improve.

What app is this???
So I've acquired an HTC Sensation and have unlocked, rooted, and installed a few ROMs so far. Stock, CM7.1, and Android Revolution HD. That last one is the one I'm on.
My battery life sucks. Whereas my Blackberry Bold 9700 would go one to two days with constant, heavy usage, this phone gets about 4 to 6 hours. My battery graph says that Display is using 80% to 90% of my battery. I've turned off auto-adjust and set the brightness to minimum, it hasn't helped. Am I ****ed?
I've tried other things, underclocked to 1Ghz, different ROMs, battery calibration, no HTC Sense account, no friendstream, disabled background data and autosync. I've tried everything, and yet the display is totally destroying my battery. Keep in mind too, I mentioned the Blackberry, but I've had Android experience before. I'm not a total noob, and I'm not a pro.
EDIT: If you've got semi-****ty battery, check my last post on page 2. It might help ya out. http://forum.xda-developers.com/showpost.php?p=19062683&postcount=20
That's an LCD screen for you. It will always be the biggest power consumer of this phone. I believe that in general, the screen will always be the biggest power consumer of a phone, but LCD is especially bad. It doesn't help that the Sensation has an average-sized battery either.
That said, I can't believe your battery life is that bad, considering you've underclocked, tried different ROMs, calibrated the battery (although I've heard that this can actually decrease batt life), and disabled background data. Make sure you have matching radio + ril in case you haven't yet. I just can't believe that if you're doing all those battery saving tricks at the same time that your batt life would still be bad. Or did you try those things by themselves? You should try several things at once, but I'm assuming you already have.
LCD screen tech really needs to hit the grave. I like qHD resolution, but otherwise I hate the Sensation's screen. I don't get why so many Sensation owners think it's a good screen. LCD is absolutely worthless outside - I turn brightness all the way up and I can still hardly see it. I don't care if SAMOLED has oversaturated colors - as long as it's usable in any conditions I think it's better. Not only is SAMOLED much brighter and usable, it is much more power efficient than LCD. Honestly the screen alone of the Galaxy Nexus is making me consider it just because I hate the Sensation's screen that much (as well as other things about this phone).
I'm doing them all at once. I flashed the radio that mike (author of the ROM I'm using) suggested because he said the RIL file(s) are built in.
I'll post a battery stats screen cap when I can, but I don't have the means to do so right now.

Edit: There it is. Normally, I don't partial charge, but I had to take it off briefly a few minutes ago. As you can see, it was hitting critical levels around 5 hours in before I threw it back on the charger. The line drops steadily usually when the display is being used.
Here's the shot that claims Display is the culprit.
I feel like android never goes into detail as to how much being on 4G drains your batteries. If you switch to EDGE (2G) only, you could see an improvement in battery life. You can get to it from Settings>Wireless Networks>Mobile Data.
If that doesn't work out for you, consider trying out Juice Defender on the market, it's helped me extend my battery life a considerable amount. It does nothing while you're using your phone, but when your screen is off, it'll disable mobile data, and every 15 min (or 30, you could change this in settings), the phone will enable mobile data for a minute so Facebook/Twitter/Messenging Apps can sync.
Aside from that, you can try turning down the brightness levels.
If you're willing to shell out a little cash, your next option would be to cop an Anker battery from eBay or Amazon. This would help the most, imo.
I have tried many things but so far the biggest thing to affect my battery life is disabling bluetooth. That alone takes about 2% per hour of battery life even if I never use it. My usage is light with some games, mail, and texting. Included is a snapshot of today's random usage. I don't know why but my display isn't listed in the snapshot.
One thing I would check is the spare parts app that hopefully is included in android. Look at the battery history->other usage->since last unplugged. Specifically the percentage of running. Mines says running is 12%, screen on is 4%, wifi on is 83%. If your phone is 100% running, then it is never going to sleep.
Is the Sensation a 4G device? if so, which carrier?
Not real 4G, max speed 14.4 mbps where available for TMOUS.

Ur comparing the sensation to a bb 9700? 9700 is not dual core or a 4.3 inch screen. Androids typically have the worst battery life when compared to iPhones and blackberrys. Also HTC phones usually have the worst battery life out of all the android phones.
How long have u had ur phone? Have u gone through at least 5 charging cycles? Did u calibrate ur battery after flashing new roms?
The other day I got this...maybe it makes you feel better...(1900mAh Anker Battery)

I have the same problem, more or less.
I had a great improvement installing "juice defender", this app cutting off the 3g as soon as the screen is off, putting it on once every hour to chek mail etc.
try it.
it's an improvement, but my battery drain remain awful. I had a HTC HD2, and was used to 4-6 ma, now, if it's under 80, i'm happy...
Turn the brightness down. I only use auto brightness in the daylight. I used a app called dimmer to turn the brightness down to 10. The minimum setting the phone will allow is 30 so dimmer turns it down more. The dimmer app is nice it switches brightness down to 10 and the next click sets it back, so I have it switch between auto and 10. Full brightness will kill your battery fast.

I never directly compared them, I'm just sharing my past experiences. I never expected the sensation to come even close in battery life.
anyhow, ill try juice defender and my Bluetooth and brightness are off and set to low. it just sucks cause I seem to only lose a lot when the screen is on, but I don't want to blame S-LCD because this seems to only affect a small percentage of users.
worst case scenario, ill buy a new battery. thanks everyone for taking a look, please excuse the grammar, on my sensation right now
@OP... don't worry about battery life. I am in the same scene as you are...
Running an HD game would drain by battery in 2 to 3 hrs with lowest brightness and everything off.. My only problem is low network signal...
if you start using your mobile as laptop like playing games etc then you get as much time as a laptop gives u... But if you use it as a phone, out will do all say..
So either change device or line with it..
In Android Revolution the kernel spends the battery. You can flash the bricked kernel and you will see the battery life in normal use under 20 hours. You can find it under android development for sensation here in xda. I flashed yesterday and with wifi on and all sync on I have 45%. 12 hours from the last charge.

I will most definitely try this when I return from work. I may have to flash cyanogenmod, which seems to give me slightly better life. is the stock AR HD kernel really that bad?
edit: okay I went ahead and flashed the bricked kernel while at work. hope it helps, but I lost 10% battery to do it and I'm down to 20% left. we'll see how it does.
From what I read we have a new faux kernel. You can check it after bricked.
Hey guys. Small update.
I am recalibrating the battery, again, yet something special is happening this time. I ran the phone down and it played a 1080p video on max brightness with wifi, bluetooth, gps, background data all on. It played the video for 15 to 20 minutes while sitting at 0%! Now, I'm currently recharging it and best part, it's been at 100% and still charging, orange LED and all, for about 40 minutes now. Considering my charger charges at .75A an hour, thats something like .50ish A, or 500mAH that I didn't have before. That could explain my pathetic battery life. Imagine if it charges at 100% for an hour! That's 750 mAH that I lost due to bad calibration, half my battery!
Hopefully with a few more cycles, and some good luck, my battery meter will correct itself and I'll see regular battery life!
edit: Two hours In, I'm overclocked to 1.5ghz, have max brightness, wifi, GPS, Bluetooth all on. background data and auto sync enabled. the screen has been on almost the entire time. current battery? 40%! that's with constant interaction, at times, I was playing games and listening to music at the same time. I mean Im using this phone to the max and its performing incredibly.
in real life, I will underclock to 1 or 1.2ghz (still an underclock since the system is clocked at 1.5ghz default) and wont have the screen on the entire time, so I shouldn't have a hard time making it through a day with moderate to heavy use I also never really use BT and wifi is a rarity. background data will likely stay enabled, but we'll see.
please excuse grammar, on the sensation right now and I just gave up the BB 9700 keyboard just two days ago, one of the only good things about that phone!
edit2: okay so I ran down the phone. it shut down just minutes before the 3 hour mark. this is very exciting because my battery barely decreases while the screen is off. on Max brightness and wifi/GPS/Bluetooth/4G on, and the screen on for all but about 10 minutes, I got about 3 hours. this is exceptional. ill do a real world test tomorrow and report back, but things are looking up. currently, brightness is set to auto, wifi is off, GPS and Bluetooth are off, processor is clocked at 1.2ghz. very excited that this one calibration actually did something!
also, I consider HSPA+ to be 4G cause its about 10 times faster than any 3G out there and it's actually been official for a while.

Edit3: It helped, but I'll be buying a Chichitech battery, ordering it tomorrow. 1900mAh better make a difference.
So its been a few days, but here's what I did to get acceptable battery - all at once:
Flash a Cyanogenmod rom, HyperSensation, the other one, Selfkang or whatever is a MAJOR battery destroyer for me. Any kernel, any clock speed, I'd lose 5 to 10% an hour just idling. I lost 15% alone playing 4 mp3s through my AUX cable. Not saying it's like this for everyone, but it was for me.
Flashed Faux's kernel, Joe's RCU from his thread.
Underclocked to 1.08Ghz while the screen is on, 540Mhz while the screen is off.
Undervolted the processor using FauxClock to -37.5mV, might go even lower if it's stable.
Ordered a 1900mAh ChiChiTech battery from Amazon, http://www.amazon.com/CHICHITEC-T-mobile-Sensation-Cellphone-Battery/dp/B0057US9YW - whether or not it's 1900mAh doesn't really apply, but what does is that I instantly got 20% more and I'm not even done conditioning. It's only 23 bucks, two for thirty. I was so anxious to try to get a battery that I next-dayed it for 17 bucks.
I'm a moderate to heavy user, I used some wifi hotspot today, automatic brightness for the display, background data and auto-sync, listening to standup comedy mp3s for 1.5 to 5 hours a day, web for probably 30 minutes to an hour a day, and today specifically, 45 minutes of Legends of Yore (fun rogue-like!) and 15 minutes of Age of Zombies.
Only two thirds of my battery used and I've been off the charger for 13 hours. My old battery would have given out about 6 hours ago, and that's if I cut my activity in half.
Anyhow, problem's solved, but I figured it'd be a good read for anyone in a similar boat.
So I've had this phone for a week now. Its a nice upgrade from my infuse 4g. But the battery life is killing me. I've tried every Tom.available specifically for the skyrocket and even the one kernel in the dev section. My brightness is 15% and I use juice defender set to every 30 min. I listen to Pandora for an hour and it drops 20%. Yesterday it was dead in 6 hours. Its to the point where I'm seriously considering going back to my infuse. Has anyone else had issues?

Currently have juice defender, 0.2 kernel (didnt update and probably wont for now), and a few apps frozen by Titanium Backup. If I hardly touch the phone, it would last 41 hours. With medium usage, (Wifi, web browse, using poweramp for some time, calls, emails, etc) It would easily last my entire day.
What apps did you freeze?

I have JuiceDefender Ultimate set to balanced, I have only the clock widget running, I have GPS running continuously, (I use Wifi occassionally), I have screen set to about 50% and with very normal usage, the battery is at about 20-25%. I have a good number of email accounts and they are polled constantly, notifications are normal (phone settings), I use the Market app and the browser a number of times a day and I hear the occasional podcast. By the way, listening a podcast for about 1 hour (I use BeyondPod and earphones) results in minimal battery usage (about 2% for an hour or so).
So, I have to say that I am quite happy with battery life.
I know what you mean.
I had a stock skyrocket running in a weak LTE market in New Orleans and it would last like 8 hrs then I rooted and frooze all the bloat ware and de-installed a lot of app that were always using the web. I manually set my screen brightness. And changed the launcher to go launcher. Getting 18-20 hrs lots of moderate usage lte and all.
Yea something is wrong. I don't even use juice defender yet my phone last all day wit like 20% when I get home at 9. I use it to talk at least 3-4 and moderate usage for internet and am in wifi a lot. Youtube umm often..Defective maybe??

Battery life is amazing for me with heavy usage. Just make sure when your not using lte to turn it off and use wifi as much as possible.

How do you turn off LTE?
look in settings, about phone, battery and see what is using all your battery. Battery life is very good on the stock ROM, rooted or not. You might also want to install Traffic Monitor and set it up for your billing cycle properly. Then watch for a few days to see what apps are using data. I do not recommend turning off LTE.
BTW there is already a very good Freeze list of Apps...

I was also having very low battery times on my SR to the point it was draining about 5% every half hour. I checked everything and everything was set properly. Yesterday was ready to pack it up to exchange it and thought I try restoring the phone. After restoring it, I now get excellent battery life. I'm getting about 1% battery drop every hour. Today tested throughout the day and listened to some music, some web browsing, a few FB posting, a call for 20 minutes and have 95% battery life left.

I've had pretty bad battery life here in the DC area (LTE is available here). It'll last about 6-7 hours with very mild use. Maybe I should restore it?
What did you do @ElCamino to reset it? Maybe I'll try that too (though I'll hate having to set it back up again).
Also, I turned juice defender back on today, and I've noticed that it seems to be keeping the device "Awake" even when the screen is off. I have it on "balanced." Can anyone give me a little advice on setting it up correctly. I can't seem to get it to let me open more granular settings.
So I am starting to wonder if there are some defective units being shipped. My wife and I both have a Skyrocket. Mine is great, been using it for 13.5 hours today on medium usage. I currently have 63% battery life left. I am completely stock, no juice defender or any other like programs. I even had No-LED installed and used my flashlight app for about 5 solid minutes.
My wife on the other hand has the exact same setup as I do. She complains she barely gets through half a day with medium usage. I charged up her phone earlier today. 7 hours ago I took it off the charger. She has used it with very light usage in that time and it is down to 60% already. When I say light usage I mean sitting on the table for at least 6.5 of those hours. Often she charges it up while watching TV at night. Takes it off the charger when she goes to bed and by morning the batter is at least half drained.

@jslanger I went to settings>privacy> and choose Factory Reset. Yes i know that you have to reinstall and setup the phone, but I am glad I did. Battery life has been great. I'm not in a LTE area but like mentioned battery was draining quick before.
Also I wouldn't recommend you use a back to restore, just in case that something with OS setup from Samsung causing this.

Search for Titanium Backup in the Android Market. You will have to check and see if it requires the pro version to freeze apps.

just to help you guys possibly, i moved some APPS to my SD card last night, at work i noticed mediaserver was second in my battery list and my phone was draining faster than normal
after moving the apps back to the phones internal, the drain seemed to stop, i also wiped the sd card just to be safe as i usually stream pandora anyways , but just another option to look out for
Weird....
So I've been closely following my battery life because it kind of sucks.
I had great battery life at home while on wifi over the weekend...about 18 hours no problem. I recharged it today at work, and was not getting great life during the day while on LTE/4G
Got home, turned on wifi, and the battery drain completely leveled out. I also noticed that while on cellular, the "Awake" bar is solid. As soon as I'm on wifi, it was able to not be continuously awake.
Not sure if anyone can comment on the reasons that this would be, but usually its the OPPOSITE. I really dunno why this would be.
Any help is appreciated!
Here is my battery life. Rooted and haven't froze any of the apps yet.
I know i

Hey good day guys, Just looking for some Battery life optimizations tips and tricks, my phone is used heavily as it is my work/personal/entertainment device, Right now Im getting around 12 hrs out of it. Anyone have any ideas to boost this?
Info:
SGH-I727R
Rooted Stock Rogers ICS 4.0.4
SetCPU (Powersaving)
JuiceDefender Ultimate (Aggressive)
Bloatware removed(with some non-essential services Frozen)
you seem to have covered the basics, you could also undervolt and keep your screen brightness low if its not a hassle.
you could try supercharger http://forum.xda-developers.com/showthread.php?t=991276 I have no clue how well it affects out phones never really had anything to compare it to.
If your a heavy user you could always consider getting either extended battery or spare batteries with a charger and just switch whenever you need.
Aside from getting extended battery, other things you can do is changing the kernel to a tweaked one such as this:
http://forum.xda-developers.com/showthread.php?t=1701189
You can set wifi/data to shut off while not in use (I use this one).
Some people get good battery life with SkyICS (Custom ROM) and I have actually have gotten 3 1/2 days of light/standby use from it which is pretty good.
I personally use CM9 with a custom kernel but with everything tweaked, brightness, undervolt, disconnect when not in use, no auto sync etc... I get about about 15-20hr light/mild use, I did manage 2 days with light/mild/standby use and maybe 1%/hr standby drain. :good:

I get like 17-20 hours with moderate use a few calls when running stock (including the various leaked stock ROMs)
When I flash a custom ROM, seemingly any custom ROM, My battery life falls to about 8-11 hours, pretty much half of what I had been getting. It's extremely noticeable, I can practically watch the numbers count down as I'm using it.
I know this is not normal. You can convince yourself 12 hours is great even with all the power saver stuff on, but our phones should be doing a lot more and we should be asking why they aren't.
Standby time is especially dismal in my current configuration. It loses just as much as when the phone is in use.
Search around, it's been answered before. Yesterday I got over 20 hours with almost 3 hours of screen time. I lose about 1% per hour when idle, roughly.

I've been pulling my hair out searching xda, other forums, google etc for answers to why i'm getting poor battery performance with a rom with virtually no use vrs 17+ hours on stock with moderate use.
I use juice defender, and nothing else and "cell standby" and "phone idle" are the two biggest issues killing my phone right now. 25% down in just 5 hours, and i've not used my phone for one thing except a quick 1 minute call - radio's are off except to check email once an hour. It's ridiculous.
Once search is working, this should help: http://forum.xda-developers.com/search.php?do=finduser&u=4394011
quick question, do u guys give custom roms a few charge cycles (aka days) before u judge battery life. The best I've ever gotten was 24 hours with 4 hours on screen time with gb based tpc v3, heavily customized. That being said the first two days I wuz getting less than 10 hours... just sayin
p.s. that wuz without the use of crap apps like juice defender

Nope.
This very issue was brought up in my last thread asking for help. I didn't know JD would be making things worse, or that it would take a few days for things to settle out.
Now that I know these things are normal, like getting 10 hours for a few days i feel a little better about the situation.
Nope, I flash a new nightly almost every day, and I still get 18-20 hours that day without a problem. If your phone isn't deep sleeping when idle, it's chewing battery, this is the most common battery drain problem that I've seen.

I have given it a few days in the past and for sure it makes a difference, but at this point I can tell right away if it's not working right. The battery life is literally like 30% of what it should be, I can just watch the numbers tick down.
The dead giveaway is that it loses battery as fast in idle as when it's in use. Which says wakelock problem like others have said, but I don't know how to fix it.
I've also noticed performance is worse in CM9 than in UCLE2/UCLF3, and that seems counter-intuitive, but there might be some performance tweaks in the TouchWiz ROM that CM isn't incorporating.
I'm using a stock 2.3.6 with some tweaks.
I froze all the bloatware and services I don't use, NFC/VPN for example.
I use faux123 .10m kernel and underclocked to 192Mhz/1.02Ghz and undervolted by 50mv - http://faux.androidro.ms/sky-kernel-010m.zip
Flashed Rogers radio for unlocked RIL - http://www.m-s-j.net/skyrocket/Radio_RIL__I727RUXKJ7.zip
Set it for only 4G and no LTE via *#2263#* and choosing WCDMA 1700Mhz
I haven't payed attention to my battery time/display on but it is definitely better than stock.
Also, if you use the Facebook app, that seems to be the biggest battery drain between it syncing contacts and always GPSing when you open it.
SetCPU profile for incall,screen off,temperature,and or battery level(increments of ten)
Also freeze or disable unused services that use cpu resources
Set your screen brightness lower
screen timeout to 15 secounds or 30
If youre really having a big issue try disabling background data although you shouldnt go that far.
I've used stock GB and ICS and have had great results by turning off LTE and also disabling WiFi during sleep. I can get nearly two days on regular use, browsing, phone calls, emails and MP3 playback.
So after 3 days of testing apps, applying a kernel, setting CPU and more,
(CPU ondemand, Governor: SmartassV2, Kernel Cymbaline 1.5)
I still only getting the same battery life as before about 12 hours, I don't understand how some people are reporting 20 hrs on a single charge with moderate usage. I looked over the wake lock apps and none seem to be stopping deep sleep, unless I have like the music player on. I don't know what else to do, any ideas?
besides addition batterys or extended batterys. And please try to be as detailed with apps/settings as possible to achieve the amazingly 20hr mark on moderate use.

Its pretty much subjective as to what people say, everyone will have their own definition of light use. When I say light use I mean, check facebook, twitter, instagram, tapatalk, boom done. Medium use for me would be like browsing the web and maybe playing a quick game of diamond blast lol. Heavy use for me would be playing a game for an hour+, using GPS, watching youtube/video/movies etc... So it will really depend on use. I've been playing around with custom kernels and usually look for ones that has UV or undervolting, downclocking is also good and using an efficient governor, some are good with efficiency and doesnt use more than it needs, say I play a streaming program like pandora and it sticks to 192mhz rather than blasting to 1.5ghz etc... So each tweak will add up.
I was driving yesterday for about 3hr with gps on and was browsing the web a lot on LTE and it drained my battery and got maybe 9hr used that day. On a regular day with "light/mild" use I can get 20hr light 15hr mild 9-12hr gaming/browsing all day. Browsing also eats power when you're in an LTE area as it drains a little bit more. So really it depends on how much time you put into tweaks and know what you're using.

Like this one for example, longest battery I had so far with very light use. Meaning I would only check for notifications and was barely on it for more than 10min at each time. Wifi was set to disconnect when it wasnt in use. And this was using an older version of SkyICS so no doubt its pretty good with battery life and doesn't drain a ton when on idle.
This was yesterdays pic, why was like 10%~/hr? I had GPS on the whole time and the radio was using LTE speeds so by the end of the afternoon/night I was already down to 5% battery life. And this is on CM9 with custom kernel but it was set to 192mhz/1.8ghz so yeah settings will make a big difference.
