Hi:
Does anyone know the best setting to use for our watch? I am trying to maximize battery life.
Thanks.
I've had this watch since it first came out and had given up on finding the sweet spot between battery life and performance until about a week ago. I came here to post this in the ROM/Kernel thread, but this seems as good a place as any:
CPU Max Freq: 533
CPU Govenor: Powersave
I/O Scheduler: noop or deadline (maybe someone smarter than me can weigh in on which is better)
Virtual Memory > ZRAM: 560 (this is where I've got mine set and the performance is SUPER SMOOTH. However, again, maybe someone smarter than me can recommend a better setting)
Hope it works as well for you as it has for me! If you find a better solution, let us know.
I will give it a try. Thanks!

In previous ROMs for other devices I had good experience with smoothass/brazillianwax and savagedzen but ever since I tried MinMax it's the best one for me.
What do you guys think?
(I/O Sched is Simple by far, there's no chance to others like V(R) or BFQ)
ondemand...
Stock user have to use

The "governor" is that piece of software that switches the CPU of you phone between the different speeds and voltages, thus it is responsible to some performance issues and the power consumption of the battery.
Or in other words:
The "wrong" governor results in poor battery duration, while another "wrong" governor may result in great battery duration but poor performance. The "best" governor is the one that switches the CPU to exactly that speed that is really needed so the system can run with full performance and best battery duration.
As user of the stock ROM you do not have the choice as the kernel supports exactly one specific governor (named ondemand). If you want to try the differnt governors try the Nova ROM of Noejn: this great ROM allows you to switch between several different governors.

I only tried MinMax and ondemand. To make it short: ondemand sucks, MinMax works great for me.

Ondemand make lags.. But damn Stock kernel only supports craps..
Hi guys.
I would like to know the differences amongst various governors. I googled a bit and both on the net and XDA I found some explanations, but not all the governors I have are properly explained. Some of them are not explained at all.
Is there anybody able to help me?
I found some info here and here
The governors I have with FM1.5 not explained are:
lazy
lulzactive
lagfree
intellidemand
smartassv2
ondemandx
Ok, some of them like lagfree could be self-explanatory, but I would be grateful if somebody could be more clear...
Thanks as usual to all!!
bump.
no one?

have you reached home yet? would be glad if you could answer
I was in Prague for a week
Ok, so, to be honest using only Google I found this:
lazy (http://forum.xda-developers.com/showthread.php?t=1276092) - is ondemand but with an added option to stay longer on a certain frequency. This is due to the fact that some CPU's dont like too quick freq changes when sampling rate for decision making is set too low. See link for more.
lulzactive (http://tegrak2x.blogspot.com/2011/11/lulzactive-governor-v2.html) - is basically interactive governor with added smartass bits and variable (as opposed to fixed amout) frequency scaling, based on currently occuring cpu loads. Has, like smartass, a sleep profile built-in. See link for details on exact scaling.
lagfree (http://forum.xda-developers.com/showthread.php?t=1272933) - seems to be ondemand but with a lessend tendency to ramp up to 100% but rather also use steps available in between 0-100%.
intellidemand (freely translated from http://www.android-hilfe.de/root-hacking-modding-fuer-samsung-galaxy-s2/185085-ist-ein-governor.html) - behaves like ondemand when the system is under heavy use, it behaves differently when the system is mostly ideling. That mode is colled "browsing mode" or "browser mode" or whatever. It seems to be some sort of "intelligent" demand sensing/analysing ondemand governor.
smartassV2 - this one should be known. It's the same as smartass(V1) but tweaked. Same code author. I heard one should use smartassV2 instead of smartass when available.
ondemandx - is ondemand with an added sleep profile built-in. I believe all ...X kernels are the default kernels but with an added sleep profile.
Just in case you wonder: I use Savagedzen, I somehow like it best. And I have to get up at 4:20am thats in 2:48h so you may excuse me if I go to bed.
thanks +1
Hope you found the info you were looking for already, if not - take a look at this: http://forum.xda-developers.com/showthread.php?t=1369817
Which combination of governor and scheduler gives the best performance for ICS Stock ? And which one for better battery life ?

Other said it is pegasus and devs say it is all the same just a little difference.

I was told by the majority it goes in this order:
1) Pegasusq
2) Lulzactive
3) SmartassV2
4) Ondemand
5) Hotplug
6) Interactive
... and the rest.
And for IO Scheduler:
1) VR
2) CFQ
3) SIO
The truth is that, this is a Dual Core Phone with 1GB RAM, and improved Android 4.03+ kernel. So the previous hardware and software limitations NO LONGER applies. Coming FROM the DEVELOPERS of governors and schedulers the best ones seem to be:
1) InteractiveX2
2) HotplugX
3) Ondemand
... then lulzactive ~ pegasusq > smartassV2
And for IO Schedulers:
1) SIO
... then the rest
The truth is you should use the DEVELOPER recommended governor and sio scheduler, for an extensive period (1-2 days) and compare them. Finding what works best for you. After that's done, then you should go further stability testing with Voltage Control. Eg, UC your lowest frequency, OC your highest frequency and UV each step to the NEEDS of your device, each device is UNIQUE and functions DIFFERENTLY.
I think doing so you should extend your battery life by 1 or 1.5hour per cycle, while maintaining or increasing performance.
it all depends on the ROM + Kernel and more importantly the user and how they use their Note.
For me, I use Performance + Noop.. But ive had good results with pegasusq + sio
The only way to get the best combination is to try them all, But give them time to perform, Dont make a decision after 5 mins of usage, Test them heavily, Do some serious Gaming + Multitasking and chose one that outperforms the rest !
I'll start testing and post results from time to time.

But the performance governor never scales down but always runs at maximum frequency. How is battery life with that? Must be horrible?!

I agree, governors even if they have the same stock names(i.e ondemand) has been heavily tweaked by the kernel dev so that you maximize performance and batt life. Start off by using the kernel/scheduler suggested by the kernel dev.
The only thing I care about is running out of juice when I don't have access to something that can charge my phone, as long as i get 10-15hrs off batt life and solid performance I'm good. Still I always bring a wall charger/usb cord with me if i really needed the extra juice.
Remember you can charge the battery but you can't charge performance

I get around 24 hours from my battery and I'm happy with that, besides I'm always somewhere where I can charge my phone should by battery run out

This sentence doesn't make sense at all.
Unless you mean you can change or recharge the battery, which is straight-forward.
But you can "change" (increase) the performance. Just clear all background tasks, go to Voltage Control and overclock the cpu frequency upto 1.704GHz (with +1400mV) and keep it at that frequency by using the Performance governor. Also overclock your gpu upto 400MHz (with +1,000mV).
Though I don't recommend that, stability issues, warming issues and possible physical damage to your processor. But use the same concept, just not Overclock too much!

That's simply NOT true.
Otherwise you have your phone in deep sleep/idle far more than the average user, barely using your phone.
Other possibility is that you've severely underclocked your maximum frequency, and have a long time in idle.
Performance governor = Always on maximum frequency.
NOTE's maximum frequency uses 1300+ mV. The NOTE's battery size is 2,500 mAh. Simple maths will tell you 24hrs is impossible ; )
But it is true I'm not saying my phone will be awake for 24 hours I'm saying I charge it roughly every 24 hours, I know performance keeps the phone at max speeds but I am human I will sleep for about 8-9 hours, so in result so will my phone.
And I don't use my phone every minute of the day I do have work to do so my battery life is what I say it is. What I consider 'average use' might be absolute minimal use to you so maybe that's why you doubt me,
I personally don't mess with voltages and things cause I don't understand them but I use note core kernel which is highly tweaked and one of the best kernels for battery life

My recommendation is lulzactive.
i use hotplug+sio on maclaws slim bean,, awesome battery life
hello,
im just wondering first of all whats the best speed to OC without permanent damage. I have done over 900 Mhz but I will get maybe 1 or 2 reboots a day so I went down to 864Mhz and its been smooth no problems. but what do you think is best to use.
also taking the first question to mind, what governor and i/o settings should I use to give the best balance between battery life and performance? I have tried smartassv2 and the battery like suffers.
Please give me your opinion for what is the best combination for my phone
Well first of all you can't have both performance and battery life.
If you are after performance go for 883 ( I think. I don't exactly remember the freq so forgive me for that) or what you suggested yourself (864) and set the governor to interactive and min frequency to 245. Personally I would set the governor to performance and Max frequency to 864 min 245 though it may sound crazy but that's my settings, phone doesn't get as hot as it used to battery life has kinda increased actually well if you think about it you will see that your phone will complete a given task in a shorter time and therefore ...
If you are after battery life then don't think about over clocking. In fact you might wanna under clock to certain level.

Greetings!
Please don't flame me for not searching the forums enough, but I hadn't had the best of luck finding what I wanted. And what I wanted was, somebody to help me put together some nice, working profiles for my S6500D (Galaxy Mini 2). I'm going to share my current settings which I'm using at the moment, but aren't working out very well for me. So, I'd really appreciate if someone would share some insight on his Galaxy Mini settings.
Here are mine:
Battery > 40°C, priority 100 CPU 245-480 interactive
Screen off, priority 95 CPU 245-320 interactive
Charging any, priority 90, CPU 245-800 interactive
In call, priority 70, CPU 600-800 interactive
Battery < 10%, priority 51, CPU 480-480 interactive
Battery < 31%, priority 46, CPU 480-600 interactive
Battery < 51%, priority 41, CPU 480-800 interactive
Like I said, I'm still in the learning mode, and this is the best I could come up with. But I'd like your help to improve it. I've noticed interactive has las lag when switching between mods, but maybe you could advise another governor? I'm using squadzone's kernel.
Thanks in advance!
Cheers!
P.S. I'm using the 3.0.7 version of SetCPU and my main settings are 245-800 ondemand/sio. Hope this helps.
Shameless bump
Sorry for the shameless bump, but I'm kinda shocked nobody wanted to discuss this thread, let alone help.
I appologise if I've offended anyone by not searching thoroughly enough, but the clockrates differ from model to model, and I wasn't able to find the rates for my S6500D, so please, once more, if anyone has some insight - share it. Would greatly appreciate it.
Thanks in advance!
Cheers!
