I'm getting 1.08x, is juice defender worth keeping for that? Or no? Thanks on advance.
Sent from my PC36100 using XDA App
Yay.
I get 1.35x on default profile while using Myn's RLS5
Back when I was on fresh I used to get 2.20x with the aggressive profile.
Battery almost lasted 24 hours with very light use.
With Myn's, it last 17-19 hours and I am willing to sacrifice the extra hours for the performance.
Are you using the Ultimate juice or just plain juice? I want to upgrade to Myns 5 but I don't want new radios.
Sent from my PC36100 using XDA App
Yes I am using ultimate juice. If I remember correctly, you have to upgrade all your radios when you switch to a 3.70 rom.
I need to get ultimate but I don't pay the bill so I have to work around it. I wish I could just use paypal to buy it -_-'

I was trying JuiceDefender, but didn't really see what it was doing over Tasker and CPU Tuner and/or smartass. It seems to me that with Tasker doing WiFi and CPU Tuner to either do CPU profiles or just setting to smartass that there wasn't much that JuiceDefender added.

You can do almost everything juicedefender does with tasker and cpu tuner if set up right. Tasker is a little harder to use (though does have a lot more capability). Basically juicedefender is an alternative to doing tasker and cpu tuner not something you need in addition to. Basically with ultimate you can manage screen off cpu speeds, turn mobile data, wifi,4g on and off by screen schedule and or an app being active.
Personally i use juicedefener (ultimate) i get around 1.8x on CM 6.1.2 and about 2 on fresh. it will all depend on your settings and how often your screen is off. I go several hours at a time where my screen is off then ussually use it for 30- an hour between breaks and has greatly increased life because of this i say ..... YAY
Before I rooted my EVO, I was using JD Ultimate and the most life I got outta my phone was 1.90x but that when I didnt use my 4G and Wifi. When I would keep those enabled I would get about 1.25x
Now that I m rooted, I get about 2.30x avg. - Again though - I don't keep my radios on all the time, I only use my Wifi when Im home and I hardly ever use 4G. I live in houston and the signal here is good when you are in the city - but where I live - I sit right on the edge of good and bad signal and it makes my phone VERY laggy and choppy b/c its constantly connecting/disconnecting from the 4G network.
I would go ahead and upgrade to Ultimate cause its worth it...
can't live without juicedefender, period. Android is crippled without it -- Google should seriously consider integrating this fucntionality into the standard OS.
Without JD, my phone is completely DEAD by lunchtime every day (~5-6 hours after unplugging in the morning). Everything is set to sync automatically, of course, so it's there whenever I pick up the phone. With JD, I still have battery at night before I go to sleep. In fact even if I forget to plug the phone in at night, I still have some (very little) juice in the morning. When the battery gets below a certain percent, it goes into super-duper conservative mode and will NOT let the battery die. My counter only reads 2.15x but I'm sure it is actually much much more than that.
I use the most up-to-date beta version with ultimatejuice, but I don't really use all the features of the paid version (I still manually toggle wifi when I am at home because that is the only place I use it.) Just remember every time you update JD you need to open up the app and re-enable it so it starts working again..

I say No Juice. Running with the stock HTC kernel, I can go 24hours with moderate usage.
To me moderate use is:
1 hour of talk
50-100 texts
2 hours of gaming (bubble blast, gun bro's, bubble blast, ect...)
30 minutes of web on 3g
30 minutes of web on 4g
On the fence
I found that juice defender did help improve my battery life a little bit. But I'm still kinda on the fence about it. At times it messes with your data connections (3g, 4g, wifi) and things like gmail and calendars are not able to sync. Not too big a deal but I'm just not sure I like it yet.
So is that a yay or a nay? Also for 1.08* is it worth it?
Sent from my PC36100 using XDA App
I'm currently on the CM7 ROM, I have juice defender and done all the minor tweaks as far as disabling wireless network location, turn off the wifi and GPS, and an app killer. I still only manage at max 9 hours before my phone tells me to recharge.
If your getting great battery life, help me and others by sharing your tips here.

Yeah, I need some help too. I get about a day and a half with no use at all, and about 10 hours with minimal use. 4 hours with real world usage... I can't deal with this. Could it be the battery? It performs like a 1 year old, used, refurb battery came with a stock phone!

Have you configured the battery since flashing the rom?
I get decent enough battery life, with light usage I can go about 36 hours w/o a charge but on my heavy usage days I usually have to use the car charger a few times a day.

all of these... biggest one is to turn off data when the phone is in your pocket. use wifi when u can, avoid using 4g unless plugged in, configure the battery in recovery (i've actually notice that this helps less than anything else for me), and finally: get an extended battery. it's worth the extra hours u can squeeze out of it. don't expect more than 4-5 hours screen on time with any rom/kernel/modem combo with a stock battery.

Yeah I also did that wipe battery stats at recovery.
I just thought maybe my expectations were too high, although it seems as if my battery drains drop pretty fast.
I would say about -10% battery drop every hour, just checking the time and send/receive text messages. Occasionally I surf the Web on the phone when on break at work. Other than that the phone is in my pocket, and after my 9 hour workday my phone demands the charger.
This is with the stock battery, so I guess this is normal unless I'm using the extended battery?

u could also run a kernel that allows for over (under) clocking/undervolting. that helps some, too
get the duricell portable battery extender, add milliamps to your arsinal in one way or another with extended batterys or whatever, if you call sprint and complain loudly and dickly they will rebate you the cost that u spend on a new battery or batt extender whatever... that being said all the above options work great, u can also use night mode on chainfire 3d to save battery, or perhaps half your pixel rate, or perhapes turn off some colors (havent seen an app to do this yet) and reset your battery memory in cwm, kill ur batt, charg while off, then cycle again like that. (theres an app for that) if your not rooted, root your phone. if you dont want to root your phone, cycle ur battery the old fasion way or pop it into a rooted phone and do it.
I used to get really poor battery life (due to my phone not sleeping as evidenced by Spare Parts app). I rooted, used Titanium Backup to freeze various apps, and got an Zboost antenna booster for the office and called Sprint who sent me an Airave for the house. I wiped battery stats and cleared my Dalvic cache and the thing the finally got me right was finding out the Amazon MP3 app was still logged in though not running. Once I made sure I was logged out of that and Lattitude (Google Map feature) and Facebook, I haven't had any problem with a sleeping phone. Stock Froyo, standard battery, but rooted. When they say a bad app keeps your phone from sleeping I think they mean an app that requires log in...although this does not seem to be a problem if you stay logged in from a browser, only from an app!

You may be shooting yourself in the foot with some of those things. App killers aren't that useful on Gingerbread since they keep killing apps that just reload on their own, and every time the reload it uses power. Just because an app is loaded doesn't mean it is running. Try letting the system take care of it. Juice Defender may help a little but it keeps shutting down data and starting it up, which means you don't get as much usefulness out of the phone and may waste power in some circumstances.
See what you have set to sync. Turn off any autosyncs you don't need, like weather screens, facebook, etc. If at all possible set them to only sync when you open the program.
I use the exchange option for gmail using the stock samsung app, which gives me push email but doesn't have to keep polling the server. I don't know if that makes a difference compared to imap, but it works well for me. don't think you have that option in CM7.
Wifi is a much more efficient way transfer data than 3G, use it whenever you can, and set it to never sleep. Otherwise the 3G radio keeps starting up again and wasting battery.
You can freeze the DRM stuff if you don't use it. I don't know if it really makes a difference but everyone thinks it does, so I do it.
Having a black wallpaper helps a little because on a AMOLED screen a black pixel uses no power.
The biggest battery killer is being in a bad signal area. If you always have 0 or 1 bars then your phone is going to always be draining the battery trying to find a good cell. In that case Roam Control may help you.
That's about all I do, and with the latest Stock gingerbread EH17 and EI22 I'm sitting with about 40 to 50% left after 12 hours, that's with light to moderate use.
I've been through the ringer with this. I'm pretty comfortable now, routinely managing to have 33% of battery left after 12hrs w/3g always on, sync always on, intermittent music listening, 2.5-3hrs of gaming and general "screen on" time (auto brightness), 1.1 GHz OC, no undervolting, and GPS always on. Here's what I'd suggest:
Flash a ROM w/ NO CIQ (thanks k0nane!) - In addition to being a leech on your privacy it's a leech on your battery. It's old news to long-time Epic owners at this point, but ditching CIQ improves battery life and overall responsiveness of the Epic. A popular stable Froyo ROM for this is SFR 1.2.
Minimize always-running services - Long press your homescreen, select "shortcuts," select "settings," and select "running services." Tap this to see what's running ongoing services (not apps) your phone is running. All of these are drawing current to stay in RAM. Things like Juice Defender, Tasker, and others show up here and draw power in doing so. JD and Tasker especially can drain a lot because they perform constant tasks as well. Uninstall them and let your phone manage itself.
The same goes for task managers and app-stoppers - Froyo and above does this fine on it's own
Freeze/Uninstall system services you don't use - This includes things like Sprint voicemail, the "Email" app, and the "SprintAndroidExtension.apk," and SNS services. You'll most likely find these on the "Running Services Page" as well. You can Titanium Backup to uninstall them, but I recommend the SDX Stock App Remover as that can restore them (TB can't reliably). TB can freeze these as well, which accomplishes basically the same thing. SNS is connected to Facebook, so if you use that a lot you might want to keep it. DRM services can also be removed, but may cause problems reading the SD card. I stay away from it.
Use Spare Parts to monitor wakelock and CPU usage - If you notice something giving you persistent trouble, shut it down. This is time-consuming, but you'll get a good feel for what apps are out there to accomplish similar tasks and which one best suits your needs.
Uninstall apps you don't use - Next time you wipe and flash a new ROM, reinstall or restore backed up apps as you need to use them and not all at once. You may find you don't need quite a few of them, allowing you to keep more space open on your phone and requiring less current to maintain them
Don't charge the battery overnight - most phones can reach capacity in 2-4 hours depending on charge level. Beyond that, holding at or around fully charged will degrade the battery by denying it the ability to release the stored energy. I charge mine in the evening a few hours before bed and top it off in the morning before leaving for work.
Get an 1800mAh battery sold for the Epic Touch - this is what moved me form "getting by" to "definitely comfortable." For around $25 (incl shipping) on ebay, I've gotten a new lease on my Epic's life. It may seem like cheating to bring in a new battery, but it makes a lot of difference WITHOUT adding more bulge to your phone (makes it a tad heavier though).
Hope this helps. Remember, of course, that what works for one phone won't necessarily work for another. Despite being the same model, minor imperfections in silicone can create individual temperaments for each phone.
I as always trying to make my battery last by stopping this and uninstalling that. Then I thought; why did I buy this phone with all of these capabilities to turn them all off
So, something like the "Hyperion Sprint Samsung Epic Touch 4G 2 x Battery + Charger" (too "young" to post a direct link)
Would fit in/work with the Epic 4G (without needing a new cover)? Even though its for the Touch?
Lol, I've been doing many of the suggestions across the board, and have gotten much better results. But I'm still not "comfortable" with my battery strength, especially when I'm unable to charge my phone all day...
Looking into your running services is a big one. week ago my battery life greatly decreased. I kept seeing market update pending and it wouldnt go away. Never update never go away. I manually updated the market and the battery is back to wonderful. It drops 2-3% at night off charger. Thats about 8 hours.
A sticky with all the main running services and which ones you can stop would be wonderful. I have sns services running. I think i can stop it but not positive. I also have sanservice running supposedly some type of samsung update. Its not doing anything but its been running for 2 days. No negative effect on battery(that i notice) but its running. Also make sure you turn location off. Ive also noticed that even when you back out of google maps its still in running services. A restart fixes that but thats annoying.

SNSservice is a Facebook and Feeds and Updates Widget service. ALWAYS stop it. It does not matter to Facebook, even if you use it, but if you remove the Feeds and Updates Widget on one of your screens, that service continues to search for it and will kill your battery in a matter of hours (it starts a "restarting" loop). Either leave the widget on or kill this service after every reboot or if you are rooted, freeze it along with DRM service.
My other battery tips are to log out or sign out of every app such as Lattitude, Facebook, Amazon MP3 (it's ok to use them, but don't just back/exit out, actually sign out of them so you have to log back in next time). Apparently, staying signed in causes your phone to not sleep and you can't find what is causing it (i.e. you can't see it "running" anywhere...people call it a misbehaving app, and you would have to delete apps one at a time to find it by trial and error).
I am running AOKP M3 with franco kernel #15.2, turtle governor, 350/1000 w/ stock franco voltages. I also modded the auto brightness levels to ones of the MID mod. I use WiFi at home; I have set the power saver to switch to 2G after 1m of screen off time. However, I an unable to get more than 2-2.5h of screen on time no matter what I try. I plan to purchase the extended battery, but in the meanwhile what can I do to improve the battery life? I have the GSM phone.
Thanks in advance!
I've tried all sorts of stuff and 2 and a half hours is the most i've been able to get.
In order to do that I was using mostly wifi, auto brightness and I had undervolted as much as possible.
I've tried all different kernels and i've just accepted the fact that with this phone and the way I use it that's as good as it's going to get. To be honest i'm satisfied with that because in order for me to get 2+ hours of screen on time it has to be my day off, otherwise i'm too busy.
Also, i'm pulling 14-16 hours per charge with 2-2.5 hours of screen on time which in my opinion is great. I just want it to last all day and for me it does.
Try LeanKernel.
I get at least 4 hours battery life with:
Version: GSM GNex
ROM: AOKP Milestone 3 (power saver mode off)
Kernel: Lean Kernel
Battery: 2000 mAh
Frequency: 350/1200 Conservative
UV: Stock
3G/HSPA/LTE: 3G/HSPA and my network doesn't support 2G
What's off: BT, WiFi unless I'm home, Sync for Calender Contacts Browser and Photos.
Brightness: About 40-50%
Daily, I use: Netflix/Poweramp/Spotify/Reddit on my daily commute. Phone/Poweramp/Spotify/Reddit/Browser+ in between commute.
Even without the extended battery like you I would at least get 3.5 hours.
#1- people getting over 3 hours of screen time are on wifi the whole time, have 4g off, are minimalists with no syncing and no voice calls, or a combination of any of these.
#2 - based on your graph you have a lot of wake locks. Look at how often your phone is awake when your screen is off. That is KILLING your battery life. Disable or uninstall rogue apps, and turn off GPS and location services seems to help with this. Also reduce your amount of sync intervals if you can.
I have stock 4.0.2 unrooted GSM with extended battery.

Look at the betterbatterystats for wakelocks; looks like lookout kept half an hour, the rest are mostly sync.
Try to remove all widgets for a while. This can rule things out.
I'm running the exact same thing M3 with Franco 15.2 except I have the extended battery. This is with almost 0 idle time. Literally playing games, rrading forums, texting, etc.

I only have the calendar, clock and palmary weather widges (6 hour auto update). As far as I can tell Lookout and Sync are the *****es - literally. But that doesn't solve the idle drain, with the phone sleeping, it seems like 2-3% every hour or something like that.
That doesn't sound right. I have everything running as well. I don't use lookout any longer though. I'm sure if I just did the idle test I can get over a day of on battery time and still reach nearly 5 hours of on screen time. That's mostly Wifi which is suppose to drain more battery life, but I haven't seen the difference from being on 3G. This is a good set up.

I think you should try removing lookout. Take for example my awake times when screen is off. I sync Gmail, photos,remember the milk, and beautiful widgets.
Also major battery awake drain in beginning of my graph is due to streaming Google music when screen was off so perfectly normal.
Sent from my Galaxy Nexus using XDA App
Alright, I will remove Lookout. What alternative do you recommend, in case someone pick pockets my phone? Preferably free or cheap w/ Internet access. I'm thinking of Cerberus, as it'll be impossible for any wanna be thief to remove; I suppose the 3 EUR license is for device, right? Does it persist through ROM flashes (i.e. based on IMEI).
As for WiFi drain, on 3G it would be worse - it's longer range thus it needs more power and if the signal is bad (lucky I get top notch at home, not so at school), it's even worse.
When I get some more cash I'll order the extended battery and a dock off eBay, then I'll have a large main battery and the original one as a reserve.
EDIT: I've added the stats for this day. Better overall, the phone was used more intensively so getting a bit higher screen on time is good. I disabled Google Talk, I see it keeping the phone awake for a significant time, but I never use it. I also get rid of Palmary Weather and switched to the built in app, I'll see tomorrow how it goes.
The screenshots on the original post show sharp increase in battery drain when there is a) screen on and b) no mobile network signal.
In my opinion, these are two if the biggest culprits. The screen is obviously a power hog, especially with max brightness, and the lack of a network signal forces the phone to increase power to the radio in order to find a stable connection.

Well with the screen there's nothing you can do; A big screen will use a lot of power, a dense screen with use a lot of power, both is even worse. If this were an LCD instead of OLED the battery life with Holo would be horrible. Turning the brightness even lower than my tuned auto levels is not an option - the phone would be impossible to use due to the glossy nature of glass. As for the network, I can't do anything about that - the school building is built from reinforced concrete, that sucks up the signal pretty well and it's downtown, where the signal is already quite shoddy; at home I have a celullar tower 1km away so I get excellent reception, not so downtown.
But I'm not complaining about those. I mean the background activity, mostly the idle wake time. I'll see what I get tomorrow now that I killed Lookout and Talk, those seemed to be two major hogs.
Seems like you have a lot of awake time. Try disabling Maps, Google+ and remove all widgets and test it for a day. If it is better now, you have ruled out signal problems.
Is there any way to reduce the interval of Google sync events? (gtalk_async_conn) When I was at home on WiFi I got a sync maybe once every few hours (seen as wake). As soon as I left and turned WiFi off the sync was like every 10 minutes, which is weird, as in the AOKP ROM Control power save settings I set it to PREFER WiFi.
Why do I get a LOT more sync wakelocks on mobile data than on WiFi when the ROM is set to prefer WiFi syncs?
best pattery save I have found is turning off various radios
I use an app Profile that can turn on/off bluetooth and wifi based upon the time of day. So it turns on wifi at 7 PM M-F and turns it off at 6 AM when I leave for work. I get great battery life, and I think it is due to the radios I turn on and off.
LeanKernel stable... all the way!!... ive tried his OC 1.42/230 but you start feeling the drainage...

Believe it or not, activating wi-fi when I'm at home has actually increased my battery life substantially. No need to even turn it off; at the end of the day, it takes about 2% of your total battery life.
Care to post the "Power saving" app you are using, TC? The one that can activate 3G after the screen turns off? For so long I've been looking for such a powersaving app.
So i installed Juice Defender and immediately noticed a sizable boost in Battery life... BUT... my Data connection was more flaky then it was at stock
So one day when it is critcal mass I uninstall it real quick so I can have the data connection I needed so badly at that moment. Well... after that the battery performance has been MUCH worse than it ever was before.
Anybody deal with this yet? Anybody know how to set the program not to mess with the data... or how to....????
My rooted GNEX config is in the sig.
I found that is messed up my data connection too but that's the most part if how it works to save your battery by switching to 2g when screen off and 3g while screen on. At least that's how its meant to be. I uninstalled it as 3g would rarely come back on.
Look into other settings to save your battery like screen brightness, auto snyc, GPS, wifi (if your not in a place with it), lock sounds, key press sounds, vibrate on touch, vibrate on key press in keyboard. There's loads of things lime that which really help.
Maybe also look into certain apps being high memory usage in settings menu and look into how many apps you got installed.

This may not be of much help, but I used it for a long time with my tbolt and never had an issue, but no matter what I did with the bionic it would almost never regain data with screen on. So I think it *might* have something to do with the actual hardware. Don't quote me, just my two cents. However, after uninstalling on the bionic I didn't have anymore issues with data than I had before installing.
Oh, and I forgot to mention that juice defender saves battery by killing the data connection. It doesn't save battery any other way.
Same deal here. I just set the app to not mess with Mobile Data by clicking the customize button under profile and going into the new Settings tab that shows up then disabling the Mobile Data option. Still testing...
2x battery
I had trouble with juice defender also so I changed to using 2x battery and I have had much better results.
Toggle the 4G by swiping down and unselecting 4G, wait 10 seconds, then toggle 4G back on. It will come back, everytime for me.
ever since Gingerbread came out, JuiceDefender is not recommended for android OS
Pretty much the only major thing Juice Defender can do to "help" battery drain is turn off your network (or toggle it to 2G only on GSM phones, 3G only on LTE phones) when the screen is off.
It generally wastes more battery frequently toggling it on/off when the screen changes state than it saves by doing so. Not to mention that you can't get background alerts etc. when Juice Defender is toggling your data around.
The only time it ever really saves you anything is if you're not turning your screen on for long periods of time, in that case you could simply manually toggle off your data if you know that will be the case. Juice Defender runs as a process in the bakcground constantly, which effects your battery negatively also.

pretty much what he said. I used JD Ultimate for a month before I gave up on it. I don't notice any decrease in battery life since I did so. Betterbatterystats showed an awfully high number of wakelocks when JD was active. The wifi "Location" feature was nice though.
Like previous posters have said, the problem with JD is that when it toggles you data, it will force your phone into an awake state which drains a bit of battery. I'd like to add that, from personal experience, if you usually have JD toggle your data on more frequently than at 20-30 minute intervals, you might as well turn off JD. The battery saved from turning your data off and the battery wasted putting your phone on an awake state isn't worth it. On the other hand, if you toggle your data less frequently than every 30 minutes, the benefit exceeds the cost and JD actually helps you save battery.
Since I need my data more often than that I have turned off the data connection management. I still leave JD on for the location-based Wi-Fi management though. That's actually useful and saves me having to worry about turning on my Wi-Fi when I get home/to college.

I'm never a fan of any so-called battery saving app.
All they do is turn off your data or turn down the brightness.

I'm a fan of Back button long-press kills app. Then i just check for bg processes of said app and kill them as well.
If i have apps that need background sync, i always make sure either to leave wifi or data on (i know it won't need much, a few KBs maybe) so that apps will have connectivity when they need it, or, if available, sign out of the app (examples: gtalk, latitude). It will cost me more battery if the app keeps trying to find network connectivity and not having it, than the drain of wifi on or data call active.

Pretty much the only major thing Juice Defender can do to "help" battery drain is turn off your network (or toggle it to 2G only on GSM phones, 3G only on LTE phones) when the screen is off.
It generally wastes more battery frequently toggling it on/off when the screen changes state than it saves by doing so. Not to mention that you can't get background alerts etc. when Juice Defender is toggling your data around.
The only time it ever really saves you anything is if you're not turning your screen on for long periods of time, in that case you could simply manually toggle off your data if you know that will be the case. Juice Defender runs as a process in the bakcground constantly, which effects your battery negatively also.

Like previous posters have said, the problem with JD is that when it toggles you data, it will force your phone into an awake state which drains a bit of battery. I'd like to add that, from personal experience, if you usually have JD toggle your data on more frequently than at 20-30 minute intervals, you might as well turn off JD. The battery saved from turning your data off and the battery wasted putting your phone on an awake state isn't worth it. On the other hand, if you toggle your data less frequently than every 30 minutes, the benefit exceeds the cost and JD actually helps you save battery.
Since I need my data more often than that I have turned off the data connection management. I still leave JD on for the location-based Wi-Fi management though. That's actually useful and saves me having to worry about turning on my Wi-Fi when I get home/to college.

I disagree. When I used it on my tbolt went from a drain of 40-60 mAh to 20-25 mAh using battery monitor widget polling at 60 sec intervals. And I never missed anything. But I used jd ultimate that allowed data when apps requested it. I also typically got 6 extra hours of use, which meant I could make it though an entire work shift vs. having to recharge after lunch. The only reason I'm not currently using it is because of issue with the bionic data not restarting. That's the reason I think it's an issue with hardware compatibility. Because even if I let the stock Android manage the data connection I still have issues with data restarting on the bionic.
Juice defender did really extend my battery but I found the only part I really used was the WiFi location feature. I started using WiFi unlock at home and got [email protected] to turn off WiFi when I'm away from home then turn it back on when I get home. Yes, I'm that lazy/forgetful.
JuiceDefender was great on Gingerbread and Froyo, but I've noticed that it just seemed to hurt more than help on Honeycomb and ICS. My battery life on my GNex, in my use case, went up when I uninstalled it, as did the data drops I'd been having.
I suspect that as stock power consumption continues to drop with new OSes, JuiceDefender is going to be viewed as a relic of a bygone era.
I will have to say that it has helped my battery but in my work environment I lose signal while my phone is in my pocket plus I can't check my phone for two hrs or more. So I would say in my case it has helped since I would forget to turn data off. I also changed my settings to toggle data every 30 min instead of the default of 15.

I was talking about JD's performance on ICS; on the Galaxy Nexus specifically. JD was great on my old Gingerbread and Froyo phones but with ICS it seems to be obsolete (under the conditions I described in my previous post at least). I don't know if it's just how ICS works or if it's because JD hasn't been optimised properly for ICS but that's how it is right now.

I bought JD Ultimate, and eventually had to uninstall it after I found it was causing too many glitches in ICS. I wasted 4.99, but live and learn I guess.
What's a good figure for battery life on the GS3? The best I've got is about 31 hours using on demand and bfq. Any one got better life using other settings? I heard someone getting about 43 hours life but that seemed to be a little unbelievable. Let me know what your getting

What you reported is definitely "the average". Most actually only get a day, if they're lucky of moderate use and have to plug in before sleep every evening and get going on charge in morning. So its more like 15 hours actually. And your 31 max is very common high end for people who've stretched it out.
I'm not sure if you're stock rom or not and if rooted either but that makes a big difference.
I'm rooted ( and would ALWAYS RECOMMEND ROOT FOR EVERYONE EVEN UF NOT FLASHING ANY ROMS AND STAYING ON STOCK. The ability to have full control is important.
Changing kernels and more importantly, undervolting, will give you that longer life you're looking for.
I'm currently on KyanROM with either Ktoonez or Faux kernel (heavily tweaking and testing both) and have this phone beautifully undervolted to exceptionally low and very stable mv numbers! Thus getting me that lovely 36-45hour average (you mentioned you saw posted elsewhere - yes it is possible and many are doing it). I basically only need to plug in every OTHER EVENING or night between 6pm and midnight depending on usage and I'm a moderate to heavy user (with a lovely 3-5 hours of screen time as well) AND I also have my phone overclocked to 1.8Ghz! Surprisingly, the oc doesn't make much battery life impact at all because the phone isn't constantly having to run at high levels, only in short spurts. Actually, due to rooting and kernel change I'm able to have my phone run as low as 192Mhz during much of its general activity and deep sleep ( which I get a ton of as my phone basically always goes into it when the screen goes off). This saves me A LOT of battery life.
I also use LTE, which is actually one of the biggest if not the largest battery hog, next to screen time of course. But with that being said I only use it when needed and have it turned off when not in use.
As for my peak I was able to squeeeeeze out 87 hours once, on my stock battery BUT that was with some abnormal(for me) measures that really help conservation. Ie, no LTE, under clocked to 1.2Ghz for good part of the three days, much less then normal screen time over the period of which I used it at lowest level with even further reduction via screen filter, I actually used airplane mode during my three overnight sleeps (which I seldom use but if you can hack it, do it! It can really save battery overnight. My current setup basically SIPS MY BATTERY AT 1% EVERY 3.5-4 HOURS OVERNIGHT WHEN IN AIRPLANE MODE), mobile data was off for most of time but did use my wifi at normal level (wifi uses less especially if good signal with few reconnects/scans), used my typical low UV numbers, kept my notification updates/syncs/wakelocks to a minimum and lastly kept my memory virtually clear if unnecessary background apps.
Doing ALL of this allowed me to get OVER THREE DAYS BATTERY LIFE. But keep in mind I seldom do many of these battery saving tips on a regular basis but some do and if you can, they WILL work to extend your life substantially!
To wrap up (this long winded post/reply) I'll give you my general UV mv range numbers and the typical everyday simple battery saving methods I use.
1.My voltage at lowest clock of 192mhz=800mv with gradual (smooth and almost linear curve) increase up to a mere 1200mv at a whopping 1.890Ghz clock.
I use NOOP scheduler with ONDEMAND governor most of the time, sometimes SmartassV2.
My screen off and deep sleep use this lowest 192 clock speed and with no wakeup lag.
2. I use my screen at 0% brightness most of the time (except when outside or in high lighting environment). I use the brighrness widget app to control this as it is easier and works better then stock settings. I actually even further reduce my brightness with Scree Filter App. That app is awesome and often use it solely for brightness control because it has full control and can dim it to basically full black if wanted. Which is MUXH lower then stock control. Fyi I use my phone a LOT more at night or in dark environment thus allowing me to dim screen HEAVILY yet it still is actually plenty bright with ample contrast in dark environments to do everything. This saves on my battery HUGE!
3. I use LTE when needed and GSM/HSPA+ when not. Seldom turn of mobile data altogether. I do turn off wifi when out and only using mobile data.
4. I use Screebl app to have screen turn off when not in use. Its great liitle app. Basically let's you turn down screen timeout to 15 seconds or less so screen is never unnecessarily on but it always stays on when in use due to the accelerometer and it knows when the screen is not flat on table! Its very annoying when browsing or doing stuff where screen isn't touched for long periods and the screen goes to sleep! But this stops that! So its always on when upright or in use and when phone down it turns off immediately.
5. Very important step and can take some time and research but making sure to keep partial wakelocks and apps keeping device awake to a bare minimum! DEEP SLEEP IS VERY IMPORTANT TO SAVE BATTERY! You basically want it to go into that every time your screen goes off and to stay in it uninterrupted for as long as possible. And many users phones are NOT making it into deep sleep due to partial wakelocks and they don't even know it or how to fix it. Not getting deep sleep can unnecessarily kill your battery!
I use a few tools here: Better Battery Stats/GSAM Battery Monitor/Battery Monitor Widget from within System Tuner Pro (which is my also my main and highly recommended tuner app for CPU oc/uc and UV,etc.).
These apps really help to determine what, if any, apps are causing partial wakelocks ( displaying in wake number amounts and overall wake time) allowing you to determine what to do to fix the problem and let the phone gets as much battery saving deep sleep as possible.
6.I'm not big on auto app killers and actually recommend against them as Android ICS does this already very effectively but do keep in mind that the more active background memory that is used, the more battery the battery is drained. So I personally kill unnecessary apps myself from the background whenever possible to save a little battery here and there. Using the apps listed above in #5 can really help to detect a nasty background app or service that is quite possibly unknowingly using a ton of CPU and/or memory, thus draining more battery and also often just slowing down your phone!
7. For those who can use it Airplane Mode is a big saver! Try overnights if wanted as long as missing notifications, emails, calls, updates, etc is alright for you. I seldom use it but it does help.
8. I almost never use my Bluetooth and GPS but when I do that is the ONLY time they are on. They get turned off immediately and really be careful with the GPS in particular because you might be surprised how many things on your phone will use it in the background, sucking your battery!
9. Be careful with sound and vibration levels. Haptic feedback too. I don't do much here but its anotherctip nonetheless.
10. Lastly is treating and charging your battery right! I found an amazing site linked down below in a couple of articles that really explains these batteries and how they work in a very in depth technical level this is still not too hard to follow. Aside from the two links I posted check out the others on the left menu as there is a ton of useful and educational info!

OK I've rambled on waaay too long here. Maybe I'll take this and post a battery savings tips thread with it lol. "10 points"!
Btw I've just received both my 3300mAh and 4400mAh capacity batteries. So I have much testing to do on those too and I plan on reporting back on them as well. Also with screenshots for data and proof...I can and will also post screenshots for all of the numbers and stats I've posted here today with my personal phone/battery accomplishments.
Hope this helps some of you out there because yes this phone can be known for terrible battery life but it CAN be tweaked to SUBSTANTIALLY IMPROVE that life to high standards and keep up with the best of them!

On Stock battery - Kyan Rom/Ktoonez kernel (at this moment)
Seems about right. My phone is completely stock and if I really wanted to I could even use it for 2 work days. I usually charge it over night though. I used it for 2 days though while at work, and with 3 hours of screen on time I was down to 7% battery. Around 40 hours on.
I was stocked rooted using Sammy kernel. On demand BFQ. I'll try on demand noop and see if that helps. My screen was about 35% brightness.

Can I hijack a little here? My battery seems to be atrocious. It was okay stock after my first 3 full charges I was getting about 12 hours and 2.5 screen time.
Here is what I've done with my phone since:
Flashed to debloated stock Rom
disabled remaining unneeded apps (example ATT wifi app)
disabled Wifi
disabled bluetooth
disabled GPS
disabled GPS autorun states
disabled 4g
disabled autobrightness, set to 15%
disabled location reporting
disabled Push email with Exchange
disabled Motion
disabled auto google backup
disabled keytones and vibrate on all button presses
disabled touch key lights
disabled Svoice
disabled streaming on googleplay, only plays from memory card
disabled Google Now
fixed the cell standby bug (even though it may not impact battery figured wth)
Uninstalled FB
Set all Autosync accounts and email to sync only once per day
No widgets (only Google play music, Smemo note, flashlight, and folders)
Running save power mode for low power screen, no haptic, and auto adjust screen to blacks
Running mostly black wallpaper, No live wallpaper.
Running medium intensity vibration
I ran battery stats and got a lot of wakelocks from googlemaps and exchange so I disabled the push email and set it to once a day. Google maps I disabled latitude, and shut down the autostarts with gemini.
It's getting to the point where the phone is basically a dumbphone just so the battery can make it while it sits next to me at work. Today I have 48% after 8 hours and 50 minute screen time and 20 minutes of google play (only playing from on SD card not streaming).
Any ideas? It seems like I'm getting less than average.
All I did was also flash debloated rooted stock. Set to top out at 1.5ghz power save on. On demand BFQ schedule. Screen brightness as low as I can to still read. And got 32ish hours. I'm going to try OnDemand and noop like the other guy said and UV a lot more and see how close to 40 hours I can get

Can u link me on the bfq? Having troublefinding what that is.
Also, is that the built in power save that limits the processor or some other software?
I believe if you flash Sammy kernel it has bfq. I am on task's CM10 and kernel and battery life seems poor compared to CM9 or stock rooted
