- 20 Global Offset should be fine
Undurvolting and lagfree don't go together. Every setting I have tested in many roms, (except stock) at some point have lag problems. So in my personal opinion, don't Undervolt if you can. Battery life is very good compared to the battery capacity. Off course it's your choice. You can try and see.

I was wondering if any of you people could be kind enough to give me some more battery tips for my new SGS3.
I'm getting around 4-5% / hour battery drain on standby. I have 2 GMail accounts on sync.
Here's what I've done:
-> Removed Kik Messenger because it was commandeering an outrageous amount of Wakelock Time (about 5-11% of Wakelock Time in 4-7 hours).
-> Installed Omega v5.0 (latest).
-> Still on Stock Kernel
-> Changed my WiFi Policy to "Only when Plugged in"
Turn off automatic synchronizatikn for fcbk email or other accounts.

What does Facebook sync anyway? I always thought it was just once to get the contact pictures. I will disable it now
I've been using Foxhound and Siyah kernel, super combo. I can honestly say it's the best performance/battery life on any android device I've used, 6+ hours of screen on consistently - wifi/gps on, 3gmails autosyncing, autobrightness, 1hr>calls, 50+texts, light browsing, redditt, Google Music... Battery life is so subjective though depending on your apps, usage, cell signal, etc.
Experiment! All things being equal, in my experience its the kernels that make the biggest difference in significant battery life improvements, with the exception of stock roms vs. AOSP/AOKP, battery life doesn't differ very much minus bloatware in the various roms. And if you're a flashaholic like me you'll actually have to wait a few charge cycles to get an accurate representation of battery performance for your phone.

Thanks for the big post! ^v^. I am going to flash the SiyahKernel. But after turning Facebook Sync and the Wifi Policy (which I found out about today).
My battery is at 93% at 2h 01m 05s (also my battery goes down to 99% as soon as I take it off the charger). So thats 6% in 2 hours which is 3% / hour ! Getting there ^^
Apparently going to 99% immediatelly after the charger is normal for Samsung devices. So I wouldn't count that as reduction.
I dont use aftermarket kernels and roms, I have disabled a few stock programs I do not use and get a very decent battery with the 2x battery saver. I had already ordered a secondary battery which is on its way actually as well, so ill be covered from there on

99% right off the charger is a feature .
Undervolting is an option as well.

Oh my! Great feature! Do you know of a guide on how to do that, or is that just a fancy term for "underclocking" ^v^
As I am still on stock kernel I am obviously still on stock speeds but I'm going to flash SiyahKernel after I finish uploading photos of my A77

I don't think there are any OC/UV guides in the SGS3 forums but you could search XDA to acquaint yourself, there many writeups on the subject. Make sure have ADB and are familiar with it before so you can recover if necessary from any mishaps. Every processor has a different tolerance to OC/UV so there isn't a tried and true method of implementing it you just have to use trial and error.
I won't get in to it too much but undervolting and underclocking are related but different. Undervolting effectively ask the processor to run with less power from the battery at a specific clock speed or frequency. Underclocking would be reducing the overall frequency of the processor depending on the load. They can be used independently or together.

Ah thanks a-lot. Would creating a profile to limit the CPU to 300 MHz MAX during screen off save battery also?
I have SetCPU installed and have flashed to SiyahKernel now but haven't fiddled with it yet.

Download extweaks from the market instead to configure Siyah. Extweaks hasn't been optimized for the SGS3 yet but it works better than SetCPU with Siyah, it also has descriptions of what each setting does.
If you aren't a gamer you could even toggle two of the cores off, definitely will increase your battery without much if any performance hit in real usage.
Plenty of focus on all ROMs have been performance and battery life has not been so good. Request a ROM that focuses on battery life, for those that are away from a charger during a 14 hr. work day.

Have you thought about purchasing an extended battery ?
Or
Simply limit your processor, brightness, radio connectivity, and use am android firewall to limit which apps can and can't use data/WiFi. Also ensure you have good settings in your task manager

I get 2-3 days out of my 2400mAh-battery, using MIUI and the forbidden kernel.
I can't complain at all about battery life.
Everything runs silky smooth at 192/1180mHz - xondemand
A little undervolting and a little gpu underclock.
I think poor battery life is more "user error" than something to call dev attention for.
There are plenty of guides on how to maximize battery life on the web and on xda.
2 tips from me, because many guides get it wrong or fail to mention:
- This app lets you schedule autosync. With some care and thought when setting it up, you can be always up to date without your phone snycing all the time. If you need to be in second-precise sync-though, it's not for you.
- Wifi off @ screen off is a myth. I have set my wifi to be on all time for months now and haven't noticed any decrease in battery life. If anything, it's better now.
I use mwakious, forbidden kernel at 1512 mhz and an anker 1900mah battery and get about 19-24 hours no problem
Try using Juice Defender too
I've also noticed keeping wifi connected all day is drastically less harsh on the battery than 3g.
I get awesome battery life with mentioned banned kernel and meanrom. I just switched to another rom and not sure about battery life there yet or i'd share
I have been using MeanRom and MikVirgin off and on. I like MikVirgin alot better, and want to use it full time, but the battery life is terrible. MeanRom makes my battery last at least twice as long, but I get worse reception. I read somewhere that the great battery life has something to do with turning off one of the cores while the screen is off. I'm not an expert, but i think that is a kernel issue.
Is there a kernel that I can use with MikVirgin that will give me battery life similar to MeanRom?
That's a relatively hard question to say which kernel gives good battery life. Because no one kernel by itself can save more battery life than the other. Some do handle the tasks and compliment the CPU better than others. It all boils down to how your kernel is set up, what governor you use when your screen is on. What frequencies on and off, overclocking the CPU drains battery quickly. Having both cores online and one off when screen off. What I/o scheduler in combimation with a governor. It really depends on how you use or phone to best suit your needs, not one combination is best. While maintaining good battery is a must sometimes you end up sacrificing from performance and your phone suffers with lags. From these experiences I have found that the cool kernel and the forbidden kernel give good balance and stability in most sense roms. Along with meanrom and common sense. Those two roms I have found to give good bettery life. You just got to experiment. While one combimation of Rom, and kernel work for one persons EVO may not be the same on another persons.
Hello,
I was wondering which rom you guys could recommend for better than stock battery life? Seems like a lot of the roms are tweaked for smoothness and speed not battery life. Currently on d3rpICS but the battery life isn't so great...barely getting 8 hours with 1 hour on screen time. If anyone could point me in the right direction I'd appreciate it. Thanks!
Meanrom ICS comes to mind. Your kernel can also play a role on battery life too. Overclocking will drain your battery, so will certain governors. Experiment around a lil bit to see what settings work for you.

How are you only getting 1 hour of screen on time? I suspect something else is the issue. Are you in an area with poor signal reception (that is usually my worst battery drainer)? Or maybe you have a runaway app. I recommend that you download Better Battery Stats XDA to monitor what apps are eating your battery.
Maybe you could try a fresh install of the ROM, but leave off the extra apps and see how it runs.

No I'm not in an area with poor reception...and the ROM was a clean install I haven't even put anything back on. I'll give meanrom a try and see how that goes. Thank you.
Coolexe's kernel UV's the screen, i'm getting 4+ hours scraping 5 hours+ on screen tme ... note not using 3g, i find 3g canes my battery.
tips.. stop the media service in running apps 'the one that often gets stuck restarting' .. mediadbmservice or something, i can't find anything that doesn't work after disabling
running 1188 -ondemand, cpu1 not forced always on and gpu3d/2d/266/200 using 'kernel tuner' and a small undervolt.. all 1xxx up to 1188 frequencies set at 1.0
I also stop apps that i don't need after their use, including 'kernel tuner', I know your not supposed to but i haven't seen any ill effect so far.
I'm pretty new to the rooting scene and having a smartphone in general, so I don't know much about what's considered "good" battery life. I'm running Nil's sense 4.0 with Snuzzo's 1.2 kernel, lazy governor with SIO. My max voltage is at 1188 and my min is at 384 (I have no idea if those are the best voltages for this phone to promote longevity; they just seemed like good values so I chose them). What do you think of this battery life I got today?

2.5 hours of screen on time ? on a standard battery? yeah i'd say thats good
Oh, yeah, standard. I'd appreciate any input that could further increase it, if possible.

There are two main power draws in the Rezound, neither of which you can "fix" assuming everything else is working properly.
The screen - it's power use is clearly the highest, 2.5 hours of screen time is pretty much the best you will get with a standard battery, the only way to improve it is to reduce the brightness.
The radios - it's power use is strictly governed by the signal strength received, the better the signal the lower the power use, the worse the signal the higher the power use.
There are lots of things you can do improve the battery use, none of them will make a significant difference for the screen or radio battery usage.
The Rezound is a high-end phone, it's screen and radios are impeccable... the problem is the cost is battery life. The best way to increase the battery life is to go to an extended battery.
yeah, honestly the only way to get longer battery life is to have screen on less. i mean 2.5 hours/almost 3 hrs on a standard battery is about the tops your gonna get
I used to have Neo's Adrenaline 2.0 Rom, and was getting on average 13 hours of average usage per day. I would text a bunch, Listen to music ~4 hours, and browse Reddit for another hour. I have YET to find another rom that can produce such impressive results. AOSP SCARFS down my battery life like no other. With the same usage, I get about ~8/9 hours of usage. Although Neo's Linaro roms do seem less laggy.

ineff deus. I modded a lot. removed nearly everything sense. tweaked build.prop a bit. kept apps frozen until needed. kept foreground apps low and prevented many from starting based on choice. I get nearly 7 straight hours on extended battery. close to 5 or more depending usage on standard
