I've been using CyanogenMOD 7 and love it (mostly). The one thing I don’t like about it is the short battery life. I'm kind of new to rooting phones so it took me a bit to get it rooted and get CM7 rolling. I was wondering if there are any mods out there like CM7 that have better battery life? Or if there's any thing I can add to CM7 to give it more batter life?
I've been using android since the first phone came out so I’m already knowledgeable in what to turn off to try and extend the battery life, but I have noticed a big decrees in batter since installing CM7.
Thanks for the help guys

You can under clock the processor when your phone is asleep. This creates better battery life.

your phone automatically underclocks your processor when it sleeps (for most CPU governors), you do not need to tell it to do so.
I'm not picking on you fyi, I'm just making sure we are giving people accurate information... there's only one thing worse than no information: incorrect/incomplete information.
op: which version of CM7 are you running? remember, the more minimal your setup (ie less homescreens, less widgets, manual syncing of gmail and whatever else, etc) the better your battery life will be. this is especially true of newer phones that are getting heftier cpu & gpus that, while intelligent with power consumption, are going to drain even larger capacity batteries relatively quick with moderate/heavy usage.
how long are we talking with battery life? how heavy a user are you? for reference, I get around 16 hours of battery life if I don't charge the phone at all from unplugging to battery dying with moderate to heavy usage (texting ~50 times a day, sometimes up to 100 emails depending on what's happening at work, couple hours of calls, couple hours of streaming music [pandora or audiogalaxy], couple of hours of games [peggle and plants v zombies mostly - both of which are resource hogs], etc).
I have just learned to get used to the fact that the phone is going to die if I use it a lot, so I've purchased three micro-usb cables and a car charger.. that way, unless I'm in an area where there is no charge-capable usb port nearby, I'm always able to get a little more juice if need be.

but i also mean setting the max sleep to 368mhz. by default its set at 800mhz. sometimes with apps running in the background, the processor may go to 800mhz without you knowing
check out 'powersave' and set your cpu max to 806mhz. should last you a nice long time like that. responsiveness suffers, of course.
'ondemand' and 806mhz is the best comprimise for me. still fine with HDvideo recording, streaming audio, Nav, etc
if you really want to make it last... clock down to 400mhz, turn off all the sync, set brightness and timeout to minimum, all the radios off (airplane mode), and the volume down, on vibrate.

But some govenors don't drop the sleep to the lowest profile. In fact almost all keep it above the lowest clock. Other kernels allow it and you can also use third party to set it lower. When the tweaKr script becomes universal it will be even better =)

It suffers in powersave because it stays at the lowest setting only. No reason to set to 806. Lol and that bottom comment is hella funny =), but if he does that his phone will just be...a waste of pocket space.
Your best bet is to do some research on kernels. If you are using cm7 to cm 7.0.3 id recommened pyros kernel. If you are on 7.1 or a nightly over 121 I believe id go with eugene's streamline5. It did wonders for mine Also there is a battery saving tips. Google G2 battery saving tips. Should be first link that comes up.
Cyanogenmod roms are known to be battery hungry. Nom nom nom.

Do you have link for this? I'm running 7.0.3.. but I dont think im finding the correct Kernal.
Mugen 3600mah = better battery life...
Can you elaborate on what kind of battery life you are getting now? How many hours, and for what level of usage?
How long have you been on CM? It takes a couple charge cycles of the battery after flash any ROM, for the battery meter to be accurate. Clear battery stats (as mentioned) then charge to 100%, let drain to about 20%, repeat a couple times. Don't drain until the phone dies. Some people say to do this, and its not good advice. Over discharge of Li ion batteries can cause them to no longer take a charge. There are people on here, on the Vision and other phones, that let their battery drain to empty, then the phone would no longer boot, forcing them to replace the battery.

All,
I wasn't going to root my baby, but yesterday was the first time I out for the full day without being able to charge and was bout dead by the 10th hour. I took Wifi off and left it on 3g.
So after that, I decided I'm going to root and load up a ROM hoping one is going to give me a bit better battery life. Which one out right now can provide me with good battery life and stable.
Thanks for any info.
no rom is going to drastically improve your battery life. For the most part this phone can get anywhere from 3-4 hours of screen on time

Undervolting is your best bet imo.
I am using a GSM Galaxy Nexus running MCR lr8 with OC/UV kernel and after undervolting I get between 18hrs and 30hrs depending on use (overclocked to 1.4GHz). Note this is my normal use, where I am also doing other things during the day - not in "just got my new phone so am playing with it all the time" mode
30hrs is the absolute max and I doubt I'll ever get that much again unless I purposely don't use my phone at all!
The main thing is how low you can UV it at 350MHz and not have any problems, then set the CPU to stay at 350MHz when your screen is off. Together with JuiceDefender or a similar battery saving app, your battery will seem like it lasts forever when the screen is off* - exaggerating slightly of course.
*unless you have a misbehaving app keeping the CPU or data connection active, like I did with Twitter last night. I shall be disabling auto-updating for Twitter now.
Note: I accept no responsibility if you damage your phone by undervolting or doing anything else!
dont look anywhere else

no custom kernel or modem required
flash it as stock, and watch the difference!
if you don't want to root,
try juice defender...
i got it on my GNEX and it is just simply awesome.
read through the tutorials and go from there.
i've been getting stellar performance.
So I switched from the iphone with edge to the Tmo S2 with Jugg 5.0 ROM + Go Launcher. I really appreciate the 4g speed. However, the overall experience is not as smooth as the iphone and the battery life sucks big time. I normally have to constantly plug the phone in whenever I can. It works ok when I'm at work but when I'm out all day my battery won't last more than half a day. It's so bad to the extent that I have to turn off my phone and turn on when I need to call or text so I can keep the phone alive the whole day. I tried Juice Defender but it didn't help my battery at all.
Yesterday I spent a few hours on XDA and I came up with these solution to my battery problem:
+DarkSide Digital Warfare v2.7 ROM (couldn't find 2.5.1 version)
+Flash Synergy Kernel over (supposed to give better battery)
+SetCPU app (auto detection)
+Zeam launcher
So far, it seems to be better on the battery. Is there anything else I could add to make my battery last longer? I need the phone to last at least the whole day without charge. I'm constantly on 4g looking up stocks, reading news, email, google voice, grooveip, facebook, turn by turn navigation, music, netflix, youtube ...
Thanks,
Welcome to Android.
From what it appears, you seem to be a heavy user. The most you can get out of a Android device with heavy usage is 3/4 of a day (14-18hrs) tops.
You have 2 choices, either you travel with the power cord not to far away and plug it when you need it or you invest a whooping 10$ and buy another battery.
There are tricks to keeping your battery healthy but lasting all day as a heavy user will be very difficult.
If this is a new phone it takes a week or so for the battery to settle in a hold a charge well. After a week or so you'll notice your battery is lasting longer. Also make sure that nothing is keeping your phone awake 100%. Some apps don't play nice and cause issues. Welcome to Android.
Note: navigation kills battery fast, when your using it try to plug into a car charger or something.

There are a lot of things you can do to improve battery.
1. Juice Defender (which you say you have already tried)
2. Limit the number of widgets you run or run no widgets like I do
3. Turn the screen brightness down all the way
4. Don't use Live Wallpaper, also, try to pick a dark coloured wallpaper since white/light colours seem to use up more battery.
5. Uninstall apps you don't use.
6. Turn off GPS unless you need to use it.
7. Turn off sync completely or only have your gmail sync. I don't need to be notified when I get a facebook message so I don't need it syncing every few minutes or every hour, I can check that manually myself.
8. Turn off animations.
9. Close background apps that are running that you aren't using.
10. Use Task Manager to close open apps when you are done using it. Task Manger is your friend.
11. Enable Power Saver Mode.
etc etc.
Those are the main things that I tend to do. I plug my phone in every night before I go to bed as well so I am not sure how long my battery actually lasts. But typically after 16hrs of use I still have 60% battery when I go to bed.
Currently my phone has been on for 7hrs 15mins and I have 87% battery. So you can do the math. I am not as heavy a user as you seem to be, but hope this helps. Peace.
Check out this video it helps show you how to save battery. Enjoy!
Thanks for the inputs guys. I should have said I was looking for Rom/Mod/Scripts/Apps... that can be flashed onto the rooted phone. I have done all the basic battery saving housekeepings as listed by Chochiwpg.

I'm up 5hr 45mins on battery and my battery is at 41%. Let's see if it will last for today. I will put Juice Defender in tonight to test out the battery tomorrow.

You could run Juggernaut with Faux Kernel and Gideon's battery scripts. Or Telus T989D stock ROM lightly tweaked with same kernel and script. Got good results on those as well. Good luck.
Btw, has anyone had tremendous increase in battery life using the after market extended battery?

If you are talking about extended batteries that don't require a custom enlarged back cover, you will not get the battery increase that you are looking for, not even close. I cannot speak for the heavy duty ones that require an enlarged back as I do not own one
Gideon's scripts are great with Juggs. Underclock it as well like 384-1080 is a great setting. Also let die all the way down and charge all the way up and repeat for a few cycles. And don't stare at your phone every few seconds either lol! Another thing are the notification lighting buttons at the bottom. Drop to 1.5 seconds.

I have the extended 3800mah battery. It's insanely fat and makes the phone look hideous. On top of that I really don't feel like the battery lasts all that long at all. It's in my pocket all day at school and by 3:30 I'm at 35%. This thing cost me 65$. Total ripoff. I'd suggest spending 20$ and buying two more regular batteries. See what that does for you all

A few things you can do on ANY ROM to improve battery life.
*) Decrease screen timeout to the lowest possible setting.
*) Adjust screen brightness to the lowest level you can tolerate.
*) Decrease the backlight key timeout to the lowest setting ( or off if you have the option )
*) Be sure to only have wifi and gps on if you are using them.
Those will help quite a bit in general however, a ROM like Juggs is meant to really take advantage of the power of your device so its probably wise to move to a different one if max battery is your goal. I love Juggs but had to move on to the AOSP stuff. Also, heed the advice above, allow the ROM a few days to "settle" before making a switch or even a judgement of its performance.
Thanks for the replies guys. So my phone lasted for 9hrs today which is a little bit of improvement. I was streaming netflix for half an hr on the train on the way back home so that may have drained the battery. I have just installed JD, will post back how it goes tomorrow.
So the extended battery is a no go eh. I really don't want to lug around a few extra batteries. I want to carry as little as possible. I normally carry my phone and my ipad but now I tend to not use the ipad much now because the S2 screen is pretty gigantic for a phone.

I know the point was already made but just to reiterate, you can get 2 Anker extended batteries (same size as regular battery) and a universal charger for like $20. This will leave you with three batteries. One for the charger, one for the pocket, and one for the phone. With this system its pretty easy to always have one full battery ready to go and one charging. The battery is small and can just go in your pocket, or maybe even in your wallet depending on your preferences. It solves the problem completely. I don't think you are going to do much better because if you are a heavy user then your battery is going to be used because your phone isn't going to be sleeping.
Good luck.

If you read my post above. I'm against the idea lugging around too many things. It's also a hassle to swap the battery and keep them all charged. I may be a heavy user but it's not like I use the phone all the time. I use the phone heavily early in the morning on the way to work and after 5pm on the way home after work. The commute each way is roughly 45 mins. In between the commutes i make a few calls and texts through GV. I don't think i'm that of a really heavy user.
Anyway, it's noon and I'm at 75% with JD on and setCPU to 384-1084mhz which is pretty promising.
Questions go in the Q&A section
Since you changed kernals, you aren't going to benefit from TDJ's battsaver script you can use with the stock 2.7 kernal.
Go lower on the max frequency. Something below 800 mhz. Setting a negative gloval mV doesn't hurt, and if you can get to -62.5, that's great.
Oh, and when using data, try GSM only...
To be honest, the larger problem with battery life is typically the user. There's no real magic on making the phone last longer other than using it less. If you're going to be power using the hell out of it by using 4g for hours streaming media, your battery is going to be ****.

Don't you think it is ironic for me to switch from the iphone to the S2 because I couldn't stand the slow 2g Edge connection then have to lower data speed to GSM (2g) just so I can use the S2 long enough?
I think the S2 is one heck of a device but the OS and Apps are not running very efficiently.
I tried the ICS ROM ARKSIDE.UCLE2:: x[BETA07.1] in the last 2 days with setCPU at 384-1026Mhz. I have had great battery life. I got home at 12 am yesterday with a 2% battery. Today it's been 7 hrs on battery and my battery is at 70%. I don't know if it is the ROM, setCPU or a combination of the two but I'm pretty happy with the phone right now. ICS is awesome too.
I highly recommend that solution to anyone having a short battery life problem with their S2.
It is a little ironic since you did bring up the comparison. What I was attempting to do was to bring the phone more into spec of an iphone to get similar battery life. You're probably going to even get better runtimes due to the battery having a much larger capacity and better screen technology. All that superior hardware packed in the t989 is going to need more juice to run.
It's great you're getting good runtimes now. From my personal experience, once I drop down to the single digit percentages, it starts lasting a lot longer per percent. If you wanted to squeeze all you can from the device, those 2000mah aftermarket cells might add another 15~30 minutes.
I hear it all the time... Does this rom provide good battery life? How's the battery life? Why is my battery life suck? So; it may have been done already somewhere; but I figured after watching and logging my own battery life, I could really help some others. I'll section this out; no specific order at all.
ROM: No matter how many times I look at a ROMs thread, I get to see a multitude of "How is the battery life" posts. You know it, I know it, and we all know it. Truth is; after using plenty of ICS roms out there; most of them have similar battery life. Currently I'm running the Blu Kuban rom, and I get just as good battery life as I do with most other touchwiz based roms. To each rom their own. Read up on the rom itself before you go blaming the rom for battery life. I've noticed the JB builds aren't the best with the battery, but we must remember those are usually noted for having bad battery life. Either way, most of the ROMs I've used personally perform rather similar in actual battery life.
Kernel/Governor tweaks: I can't stress this enough. Governor's and Kernel Thread. That thread will teach you more than anything you want to know about kernel and governor tweaks. Some of these governors can send your phone to absolute battery immolation, while others can set your phone up to last 2x as long. I prefer the more conservative approach and end up with a ton of battery left at the end of the day. While these settings are important, the most important is yet to come.
APPS. I can't stress this enough. I used a quite a few different setups to find what all really uses battery, what doesn't, and what I should to to maximize my own battery. For those of you who don't know me at all, I work ten hours a day, and I used this time frame to measure the battery usage while it's sitting in my car for ten hours. I have a Trexcell 3800mAh battery, so it's roughly 2x the power as the stock battery.
What's the number one usage on my device? NOTIFICATIONS! All of those apps that automatically feed their greed by getting updates from the servers or whatever. Facebook, Hotmail, Tapatalk, and EVEN just the gMail app could drain 10% of my battery in ten hours. Let me show you my findings.. These are the normal apps I use that can automatically update over certain time frames.
Hotmail
Tapatalk (Xparent Red version)
gMail
Facebook
Now if they all automatically update on the stock settings, ten hours of work will mean I'm coming back to a phone with only 75% battery. With only 4-6 hours of deep sleep! That means these apps are waking my phone up to do whatever they want for quite a while. With all of them set to be manually updated; I come to 95-97% battery life. That's quite a stretch in a difference you know?
So, I tested each with the others off and here is what I found. (I tested for three days, wrote my results for each day, then switched to a different app)
Hotmail set to update hourly would leave me with about 90% of the battery at 4:30. Average deep sleep times were in the 8-9 hour ranges.
Tapatalk was setup stock for 15 minute updates. I'd lose at least 10% on the battery every day! Deep sleep however would range in the 8.5-9.5 hour range.
gMail was set to update hourly and would leave me with 95% each day with only keeping the phone awake for 30 minutes on average.
Facebook updates are odd; since they don't happen all the time. So I had a good friend post on my wall three times a day and noticed that it would eat a LOT of battery, usually 10-15% and keep my phone awake for about 30 minutes a pop.
Now I must note, for my tests I had almost nothing installed on the phone aside from the apps listed and the basic apps available in the blue Kuban rom. For the tests, I set google voice to do not disturb so phone calls and the like wouldn't be an issue.
With all four of the apps set to default updates however (no messages on facebook aside from one day), the battery life ranged from one day being 67%, second day ended with 74% and the third day left me with 72%. That's a LOT of battery for just sitting in my car.
After these findings, I've switched all my apps to update only when I manually refresh them, and I'll tell you what, my battery life has never been greater. I literally come home with 95% battery on average and can sit and play on my phone almost all night without charging until it's nightly stay on the charger.
Just some other tips I've learned along the way.
Wifi is a battery slaughterer if it's not connected. Driving around the city and having the wifi detect all kinds of networks is just battery slaughter. So, my rule of thumb now is, when I leave the house the wifi goes off. It's true that wifi uses less battery than 3g and 4g, but when you're picking up random networks and the radio is searching through them, it's just no good for the battery.
Brightness, it's a key. I can't stress this enough, if you don't need 100% brightness and want better battery life, turn that screen brightness down to an acceptable level.
As an ending to this short but sweet little tidbit of information, I'd like to share why I wrote this, did all this testing, and why it mattered to me since I have an extended battery. My phone is my link to the world, my family, potential jobs, and just my favorite handheld entertainment device. Me and my fiancee` both have the E4GT, and I have the extended battery. She has the stock battery and it doesn't last long at all for her. So my plan now is to work with her on her battery life, and give her this extended battery. I won't need it since I literally have to try to get to 50% battery life with it. I usually end up plugging my phone in for the night at 65-75% battery. I just figured I'd share this with people on the forum as maybe a different approach to saving some precious battery. If you like it, tap the thanks button. If you have any ideas to better this, let me know!

Just like to add for people to check their batteries lol...these stock batteries that come with the phone don't last all that long..a lot of these batteries go bad quick and need to be replaced (a simple spin of the battery will tell you if you need it changed)...and for a lot of people to stop constant deep charges and to charge when needed instead of pushing the battery to low critical levels
-TeaM VeNuM Like A Boss
I will also add that if you're going to try and mess with settings such as I/O or over/under clocking do your research so you don't jack your phone trying to save a battery. I say this from experience lol

I understand leaving your phone on all day long so you can see texts and missed calls and stuff but why not just turn off your data during the day instead? I use this widget when I am in a poor signal area, don't need data, or sometimes overnight https://play.google.com/store/apps/details?id=com.farproc.data.enabler&hl=en Simple and effective and you can let your apps sync for times when you are using the phone
Undervolting also helps a little
Step 1. Install CM10 or ParanoidAndroid.
Step 2. PROFIT!
Battery life between stock and AOSP is night and day.
The questions about battery life are there because not every kernal is the same. Especially ones that are early in development. Pretty much every AOSP rom will defer some amount and even more so if 1 of them is in its early stages.

What battery problem I'm, all good

What most people need to know is no matter what tweaks are applied.. YMMV. It's all down to the user.. Best way to save battery on your phone.. Turn it off!!!! lol But I agree with the things posted. I'm always messing around to find the best settings.. So far i've gotten over a day (1d 3 hours) with over 2 hours screen on with my setup. Which is great for me. But all in all, it's how i use my phone.

Just like to add for people to check their batteries lol...these stock batteries that come with the phone don't last all that long..a lot of these batteries go bad quick and need to be replaced (a simple spin of the battery will tell you if you need it changed)...and for a lot of people to stop constant deep charges and to charge when needed instead of pushing the battery to low critical levels

What do you mean spin the battery? As in literally put in on a counter and spin it?

Yes.. If it's spins that means it's bulging.. And that equals a bad battery

I wanted to share some of my thoughts and experiences with battery life on my E4GT.
On GB I had great battery life...As soon as I got on any version of ICS I started having battery life issues. I eventually learned that my battery was buldging so I ordered a new one. Once I got my new battery, I thought life would be grand...NOT so much!!
Over the last month or so and ROM after ROM, tweak after tweak and even going straight stock I figure it was actually the device itself that was the problem...AND it was the problem from the day I got it last Dec. From reception to battery life to buzzing camera.
Something I've seen as is that "freezing" an app doesnt always disable it...I've had to completely uninstall something to get it to not run...even though its frozen and all of its startup references are disabled in Autostarts.
I dont care for the stock browser, but I've learned that 3rd party browsers such as Firefox and Chrome continue to run and use CPU even after exiting...Now, FIrefox has an actual "Quit" option while chrome doesnt...So if you Quit out of Firefox its ok, but unless you close your tab in Chrome it just keeps on chugging battery power.
A TEP replacement phone is what finally resolved my issues!!
I've only had my new phone for 2 days now, but I'm already seeing better battery than before, plus better reception and a camera that doesnt buzz.
I've got Agats ROM with the BluKuban 1.8 Kernel. This Kernel has a few more options enabled so I use that but I like how Agat put his FI27 ROM together.
Thanks for reading...
Found this one to be very helpful (written for the nexus but some does apply to our device):

Also if you have a newer version of maps, make sure to go to settings-location settings and disable location reporting and location history, these two kill your battery when turned on.
I know there are hundreds of these threads but i was unable to find the information that I'm looking for. But my guess is there is no real answer to my question. But i've been wrong before. Please bear with me
Here goes.
I want to know how to maximize the battery when USING the phone. I dont care about wakelocks or sleep time etc.
I am interested in getting to max out the usage time.
For example when I stream radio and surf the net and text. My phone lasts 2 hours with max birghtness. That seems really short.
- I've done all that I know to minimize power consumption with turning off sync, settings, etc.
- I have tasker starting and stopping data during screen on/off.
- I have the phone UV and under clocked.
- I Limit my phone to 3G only, with no LTE
- Also signal is not a problem since I can stream and surf without an issue. With areas with poor reception. I don’t even use the phone really
-*I also have all the chats turned on include facebook, whats app, etc. Once again, phone is awake. and I'm concerned with its ON screen usage battery time.
- I even have the second CPU setting on conservative. (when set on ondemand it drains even faster)
But during usage, its terribly short! What can I do to prolong the life?
The battery was always like this and I dont believe its defective. With regular use, checking phone (once or twice every hour) can easily last a day. But during multitasking usage I notice the drain to be 49-59% per hour according to battery spy.
I know I can uninstall battery spy/BBS to conserve battery. But I'm looking for what some are reporting (4-5 hours of on screen usage time).
Looking for some guru-like advice Thansk in advanced
Personally, I get the best battery life out of the stock kernel of whatever particular ROM I'm running. I stick with tw based ROMs, and I greenify almost everything! I consistently get between 5 and 6 hours of "screen on" time with the stock battery.
You never said what ROM and kernel combo you're using. I know that I get 3 to 4 hours of screen time depending on the apps used and the connections utilized (wifi, signal strength, LTE or H+, etc). 2 hours definitely sounds low though. I'm using stock debloated ROM right now and stock kernel. I have not modified voltage or clocking in any way (yet).

I didnt really notice any improvements on the KT747 vs stock kernel.
I greenify everything except for the messaging apps. But then again, when my screen is on, i want ot be using those apps.

Using tune in radio while texting on go sms and surfing using chrome with 7 tabs open

You're doing heavy multitasking!! It's going to eat the battery, sorry, but no one's going to post a magic "cure" to increase battery life! Buy an extended battery... Problem solved.

Websurf and radio or text and radio is just 2 tasks occuring.
Well I can say that running on Wifi, I can get regular battery life about 4-5 hours of use and over 20 hours of idle time.
The radio seems to be the main culprit, so the question is..... what can be done about that?
I'm asking because
- I flashed diff modems and seems to yield same results
- other S3 from my friends seems to last longer with multitasking
- signal....strong or weak seems to produce same drain.
Battery?

I've had the same problem. I couldn't get the same battery life as others I know. I always turn my GPS off if I didn't need to use it. Google now seemed to kill my battery so I stopped using it. But, the one thing I did notice is that the battery stats can be a little deceiving. If I left my phone off the charger and didn't use it for 10 hours and then started to play a game, it would look like I was getting good battery life as I would have about 60% battery left. Now if I played the game right after unplugging my phone, and then after the same 10 hours I'd be around 40%. Hopefully that makes sense.
One thing that I did do to overcome this was get an extended battery. It does add a little bulk, but now I can use my phone like I want and not have to worry about my phone dying on me at night. I can even forget to plug it in and still have battery the next day. For me I got the hyperion 4200 battery. The Zero Lemon seemed just to big for my tastes.
The other thing is also the ROM. At times I have found the same ROM but a different version exhibited different results. All ROM's offer something different so it is a give and take situation.
I hope this helped.

Yea my gps only turns on when my map turns on via tasker. I also dont have google now on.
Ya i understand what you mean on the percentages.
Ive seen people wiht great battery life, i wanted to try to acheive that without an extended bat. I was wondering if there was somehting that was obvious, or some radio battery drain fix. (I even tried only 3G, and still drains)
Thanks

It's a little hard to compare, but right now I'm on a 4.3 ROM and the battery life has been exceptional. Otherwise the next one that has been closest for me in terms of battery life has been Dandroid. Also, it's hard to judge a ROM after a day.
I guess I should have asked if you have tried or have any interest in a custom ROM.

I tried customs like AOKP, PA, CM etc before. I dindt notice a gain in bat life.
I do enjoy's stocks stability so I would like to find a solution with my stock phone. But doesnt see like theres one....

I've had a hard time getting really good battery life from the stock ROM. At best using greenify, I could prolong it a bit. If you are interested in a stock ROM with some tweaks, I always suggest S3Rx, or Dandroid if you want a slimmed down version without the bloat.
You can always try the power save mode as that does seem to help some, but you may experience some lag.

Ive frozen most of the bloat, greenified everything, plus I unclocked and under volted it, so any lag I would feel from power safe wont affect me since i believe power save throttles to 1350 ish .
