i have been a faithful user of franco for over a year, stock clock speed, on demand, noop, and -25mv across the board was good.. but not great.
i have used it on Gnex, N4 and now N5....
i am now giving Faux a test run on my N5... slightly better batt life.. not saying to use either, just saying that in order to get the best, u have to try different things.. both kernels are great IMO
try by making changes for a day or two... get a feel for your phone.. when u make a change thats bad, batt life will be noticeable fast.. u will know
try companion apps like battery guru, battery wakelock indicator, and or greenigy...
just gotta keep an eye on what uses the most mobile data, and what wakes ur device the most... u want the phone to sleep well, which will give u more juice when being used.
rule of thumb, just because it feels faster, but gets hotter is no good... watch changes that make phone hotter... (like a car engine... too much gas or too little gas can increase combustion heat and the engine can detonate)

[Battery] Recommend widgets/apps/roms/packs/anything what could improve O3D's battery
- I found some apps what helps, similar to task killers, but they seems to be abit 'better' in some way, not sure if task killers are actually good, but I will give it a shot for a day or two to see some improvement.
- What about these performance packs, are they really improving performance, if there is such pack out, is it possible to change it to battery saving pack which will lower your performance in exchange for battery life and how long will it last longer if will made such pack?
- Custom ROMs, can they actually increase battery life without killing performance or maybe boosting performance AND battery life? and is there any good ROM out yet for LG Optimus 3D?
- Is it possible to use LG Optimus 2X rom's for LG Optimus 3D?
* TESTING:
- Battery doctor, it's task killer + battery monitor + log/graph for charging etc etc, will try it out and will see how good will it improve battery.

Software can have a great impact on battery life and custom ROMs can help without losing and sometimes even gaining preformance.
There are NO custom ROMs out for O3D, the phone is just a few weeks old, ROMs takes time, O3D will probably take even more time than usually since the 3D is new to the platform and to the once creating alternatives.
However there are things happening on the ROM side but don't ask for a ETA etc since there is no way of telling and people do it on their free time.

Nice to hear that, about performance improvement regarding to losing it.
What about other similar phone ROMs, like Optimus 2X, possible to import that in O3D just to add this 3D space seperate or maybe just make Sense 3.0 with 3D space. I'v heard Optimus 2X is same as Optimus 3D, it's just some features are in 3D, but rest seems to be same as in 2X?
Can someone please post some example of real world use versus battery life, so the people can get a feel how much the battery lasts on average.
Thinking of getting myself a O3D but i am concerned about battery life.

You won't get 24 hours out of the battery I charge mine in the morning so its full at 9 ish and by maybe 9pm it can be around 30% or less but that is best case scenario.
I think if you don't have a car or a way of charging this phone a spare battery is needed to guarantee a full day.
Would be interesting to find out if the 1900mah battery's I seen on ebay make any difference.
I'm trying juice defender right now...

No the 2X or any other phone doesn't have the same hardware, the chipset in O3D is completely new (to the smart-phone scene), some things might work but something that saves battery on the 2X might actually do the opposite to the O3D, but have no fear, in general all Android phones get better at battery handling and performance as new ROMs are released both Official and Custom, also Android itself is getting better and since this is a dual-core phone 2.4 that is said to optimize for dual-core will feel a big gain hopefully
Juice Defender and other battery logs and optimizers made it worse for me. I leave gps and wifi deactivated until i need it,screen brightness on auto. I keep mine loading over night. I leave home at 7am and am back at 6pm with 40-60% left on my battery.moderate use,some calls music email surfing. Im really happy so far!

Just need to be patient. Afterall it is a very new phone.
I am getting the 1800 battery myself. it'll give more juice to the phone. Also if no task killer is used, you will experience a much faster drain in battery. There are tons of apps opened by default. So a task killer with careful plan will gain quite a lot in power saving.
havn't seen alot improvement from battery doctor, but atm waiting on new battery to arrive, will see how long will it take on new battery and is it gona be better then stock one.
also now using juicedefender with aggresive profile, will se how will it boost my battery life

[Q] Question about Kernels

Hi, my Triumph should be arriving in the mail in just a few days and i was wondering which is the best kernel or ROM and Kernel combination that is best for battery life? I've heard that battery life on the Triumph is not so good. Maybe it's false but i would still like to know.

The battery life is a lot better now with the latest builds of CM7 and MIUI.
I just use CM7 and leave wifi and bluetooth off, no juice defender or anything like that and I can easily go all day with no charge, typically about a day and a half and my battery is getting low but it really depends on what you are doing like games, wifi, videos and whatnot.
Before I think there was a problem with the battery draining while in idle but things have cleared up since then, There are also third party kernels you can OC and everything, but you can use them to undervolt as well to save some battery if you know what you are doing. over on androidforums there is a lot more chatter about this phone, just so you know.

Thanks. I got my phone today and im loving it so far. Do you know which of those third party kernels are good for battery life and that i can install over stock? I'm not quite ready to install a ROM yet but i already did the HTC Thunderbolt Build.prop tweak and obviously im rooted.
It's usually not the kernel but whatever governor you have it set to use. Even the stock can get improved performance if you switch the governor to such--”performance”--but I'm probably not the guy to tell you about which one is best.
I also have the silly feeling a lot of misconceptions abound here...in the form of ”I changed this setting and now my device lasts longer..., oh btw I no longer play with it 24/7.” In other words, use drastically impacts battery performance. JuiceDefender is an amazing tool but it won't do you a bit of good if you're testing out your phone's Adobe Flash capabilities regularly.

The Savagezen and interactive (not sure if interactive is on any of the kernels for this phone.) gov isn't that great. At least not in my experience. I had SmartassV2 on my girlfriends phone and it got ~3600 on Antutu benchmark at 1.5 and when I used Savage at 1.5 she got ~1700. The interactive gov made my friends Dinc2 noticably slower. Just switching home screens it lagged to the point it was hard to get into the app to change the gov.
CM7 + TheOC kernel allows adjusting voltage & overclock or underclock. You really should flash a CM7 ROM. Having it just rooted can be dangerous because you're not using a custom recovery to make a backup image, and if something messes up, you don't have a backup ROM to restore. Going to a different ROM forces you to make a backup, then there's a backup to restore if you mess things up.
Governors just tell the CPU how fast to ramp up to a certain frequency, & how long to stay there. It's hard to balance fast ramp up (less lag), and low battery drain (spend more time in the lower frequencies). I like interactive/x, find that smartassv2 spends too much time in the mid frequencies (~500) even for light work. Using the app CPU Spy helps a lot to see what's going on. Also it tells you whether your phone is sleeping properly when screen is off, which is a big factor for battery drain.

What is undervolting and how can it save my battery life?

I have a Nexus S with CM7.1 and I am using the Glados Kernel v1.10 BFS.... I have my clock speed from 100-1000 on conservative... my questions are, what does this do? How do I do it? And how much battery life can I usually save? I searched it up, and I haven't really found too much stuff in depth. Thanks

I'm not sure anyone's even done any extensive testing, but I can tell you that kernels such as the Trinity SEUV kernel have a serious increase in batt life.
I'm talking 8+ hrs extra probably, at least. Now each person is different, so light users like myself will benefit more, but the difference is definitely noticeable.
That being said, it depends on the kernel you use, and how often you use your phone.

In the building I go to school in has nearly no service. I get edge at most when I find a spot, I had GPS on, brightness mid and all the same clock speeds.... my Vibrant got more battery life with the same clock speed on CM7, I had 27 when I left, I usually get 60something on my Vibrant. So what should I do, and how can I underclothing my device using setcpu?

unvervolting , as you can see from this word , under --- voltage
battery output juice to hardware such as CPU , screen , antenna ... etc
let me make an exemple , let's assume one battery has "1500" juice , if you output 50 juices per hour , then you can last about 30 hours , follow me ?
unvervolting reduces this output juice , let's say , down to 45 juice (you can not reduce too much due to stability and something like that) , then you battery can last about 33.33 hours , this additional 3.33 hours comparing to 30 hours , is extra battery life you got by undervolting .
of course this is not exactly how it works , but more or less, i think you can take the idea of it.
duration of your battery is very much depending on your usage.
3G data connection and GPS are battery killer , i have brainmaster's MIUI + franco kernel , 100% battery = 2 hours 3G data = 1.5 hours GPS navagation.

At what level should I start undervolting? I have it at 800mhz with 1125MV on lazy, is that fine to start with? I keep rising it each time it crashes on me( I started from 1025, worked my way up when I got random freezes). Do you recommend another kernel or something? I want the most power with the most performance. I heard Trinity was good but I may need to revert back to stock because the thread advised me to flash from stock for the most promising experience.

Here are my settings, once again, good starting point.
http://forum.xda-developers.com/showpost.php?p=19258876&postcount=1889
Some users reported that they had to bump 100 and 200MHz to 900mv and 400MHz to 950mv. To each their own, we all have different phones.
i have been doing affect of various variables including uv on battery life...
by changing one variable at the time..
in my testin.. undervolting actually made battery drain worse...

I'm sorry, but I fail to see where exactly you've proven that undervolting gives a higher battery drain in those tests.
Your methodology isn't scientific enough, although decently documented you have different usage patterns depending on the day. Sometimes you're playing a game and browsing the internet, others you're just idling all day.
On the undervolt test with Franco 25112011 kernel, your undervolt isn't even stable, leading to a reboot during a game and a battery stats "bug". Your screen was on 26 minutes more. Just the fact your undervolt isn't stable will make your battery drain faster. There's not only reboots and force closes as symptoms to an unstable undervolt.
The good way to test it would be by using a much more controlled environment and test patterns. Airplane mode can be used so as not to suffer from a bad reception or receive text messages/calls, a task (or multiple tasks) can be ran for a very specific amount of time, no user input other than starting the task and stopping the task should be done and the undervolt should be deemed stable.
Anyway, I can and will vouch for undervolting components, whether on a smartphone or a computer. I'm sure Trinity kernel users would agree too.

personally , i don't use undervolting , because it doesn't really effect too much on battery life
i didn't actually try , but i think undervolting could give you maximo extra few hours of battery life .
i'm using franco kernel , and 100 - 1000 with lazy governor
you minim should be 100 , 800 is not necessary
and for 1 GHz CPU , handle normal processing is enough
and i do think , that screen takes more juices than CPU ...
----------------------------------
i suggest you should try my way , buy an extra battery piece , then you won't worry about battery life any more ...
like me , i have to use phone very carefully back the time i didn't have second battery , sometimes i got out home about 8:00 AM ,and got back like 8:00 PM , when i back home , battery is nearly dead ... less than 10% .... = =
but now , i have second battery , i can use my phone whatever and whenever i want ...
i am in Spain , battery cost me 8 euros , if you can't find Nexus S battery , you can also buy Samsung i900's battery.
watch out , i900 , not i9000 , it's same battery , can be pluged-in in battery slot.
so , why did you waste days and days to search , to test , to set , to ask in order to get more battery if you can solve this problem with only 8 euors ???
but ... for real , these undervolting or overclock or underclock or what , does give you , hmm , how to say ? sense of fufillment , it's kinda good ^^
Some people enjoy travelling light, not having extra peripherals in their pockets and such. I already have enough stuff with my phone, keys and money clip without wanting to bring a battery somewhere in my dressy pants.
I read somewhere (and i think it was in this forum) that for the Nexus S the profile in SetCPU should be ondemand or conservative. I'm running Koush's Alpha 12, SetCPU "ondemand" and JuiceDefender Ultimate on "balanced". I've been on that for a week or so. I think the battery life is better than what i had running stock. I'm okay when the phone can make it through a day (like 16 hours) with normal use. I charge it at night anyway.

well , i think it depends on what kernel you use
some kernel's author would suggest what's best for his kernel.
also juicedefener or something , it's most likely by automatically shut down your unnecessary functions like GPS BT WIFI 2G/3G ...etc in order to save battery life.
i have been trying some of them , doesn't gimme much effect , probably it's just psychologic effect, you know , people would see what they want to see , also i have seen one application (Antutu something , i don't remember exact name) that reduces power output to hardware in order to save battery life , i think only that kinda applications can acutally save power...

it depends , look over your older kernel isntall zip file , check out if they put any files in directions (/system/lib , /system/modules , /system/vendor ...etc) , if so , delete them manually or check your new kernel zip file if it will overwrite the same named file ,in that case you don't have to detele these same named file because they will automatically be overwritten, otheriwse you do have to delete thoes file which won't be deleted or overwritten automatically.
...
i always just directly flash it ... if comes problem i just reinstall the ROM in order to get clean system and then flash the kernel.
some kernel like GLADOS and FRANCO has script to clear older files
but , anyway , back up before install any thing that could effect on system.

Yeah I just did that and it broke the wifi. I went to factory settings and installed Trinity, going through my normal routine tomorrow and going to see how long the battery life goes, apparently the performance is great at 880mhz and the voltage is pretty low.

I sometimes have a dress shirt or a polo with an additional pocket. Nevertheless I like to travel light, buying a second battery, while a good idea, is a poor solution to an unoptimized system.
too much undervolting can and will cause more battery drain. there is a fine line that can be crossed from battery savings to battery loss. after a certain point, the phone will end up working harder to get where/what it needs because there isnt enough voltage, leading to the loss.

amazing battery.. better possible?

I'm using current venomxl Rom with elemental kernel (all default other than max 1.5ghz and flu overclock off) and getting what I feel are amazing results on battery life. On phones of the past, aosp style roms pulled better battery life, but I saw here in the forums people were getting better battery life with sense roms? Is that true? I posted a screenshot below of my battery life, sorry couldn't figure out how to get jpg link from dropbox app.

Would be nice to hear what Rom/kernel combos others are using and what kind of battery life you are getting.
Put the picture in your public folder. Right click on the picture and click copy public link, or something to that effect then paste the link in your thread.
In any case, the only things you could do to get even better battery would be to undervolt your processor and maybe underclock as well. Some phones become unstable however and while I noticed the general ui and most apps run fine with a clock speed of about 1.2ghz, some, more CPU intensive apps do lag a bit. You can also disable radios when not in use. I actually use juice defender to do this for me automatically, which is pretty handy though not everyone likes the idea of having an app do that for you.
Last but not least, if your radio signal seems low most of the time, you can try flashing different radios to give you a better signal which will, in turn, increase your battery life.
Hope this helps, maybe others have had different experiences?
I use viper and bulletproof right now ad I wanted a stock kernel with swipetowake
And this holds up damn well in terms of battery life. Never used elemental for long though so not sure if it's better or worse.
*edit* I forgot to add, you can also turn off fastboot. Your phone will take longer to power on but saves some battery life.

Such reports are often just anecdotal and very subjective. Like you, I've also seen people claim better life on AOSP or certain ROMs on various devices, but never really experienced it in any consistent or meaningful way. Battery life often has more to do with the radio and reception in your specific care, than anything. Sure, various ROMs on various devices may have some subtle difference in battery life. But unless you are very methodical and scientific about comparing them, there are just too many variables involved, and you are often just left with subjective reports and placebo effects.
Can't open your pic. But if you are satisfied with the battery life (enough to call it "amazing"), I'd just go with the ROM that has the features you like the best, and leave well enough alone.

undervolt and underclock ... ?!?

since i use my galaxy s6 for basic stuff , browser viber whatsapp , ebay , amazon , no games at all , can someone help me to undervolt and underclock my phone sisnce i dont need all his power , i like to to it to gain extra batterylife ,
i use arter kernel 8.2 and v11_exposed rom ....
i miss my old experia z3 with 8SOT and 2 days battery life
I get pretty good battery life on mine. Undervolt and underclock is the same thing. I don't understand why u would want to do this to a great phone. Buy a Nokia 3210 you should get loads of battery life and fast enough for you
My stand by time is easily 2 days just using basic things. I do like to use my phone so I do get 1 day which is good enough for me.
Check the wakelocks that should help way more the undervolting

Not the same thing at all! Undervolting is more sensitive and gives better results although very risky!

Ya I understand! I don't see the point in undervolting unless you have heat issues which would make it more stable. I know u can extend your battery life a small bit but its not like u well get days out of your battery by undervolting and underclocking.
The best thing is kill the apps that keeping your phone awake. That would save more battery but at the end of the day you will still be plugging your phone in to charger.
What they need to do is improve battery's
Agree, let your cpu/gpu handle its tasks. For others, maybe they preferred on doing this undervolting stuff etc.
Others wanted to freeze wakelocks, alarms, services just to lower battery usage.
I find it funny LoL *kidding I would not bother buying S6 at the first place if thats how you usually use a phone. But it is your choice
You could opt for units with larger battery capacity but with good SOTs and reviews.
