SetCPU Settings for Optimal Performance

[tcleg]

I've read a couple posts on SetCPU profiles that conserve the most battery life but never one that puts performance first.

I wanted to see what others had in mind for the best profile (or not profile) settings to have on SetCPU in order to get the best performance without much heat generation.

As for me, this is what I have:

1) Priority: 30
Battery < 101% , 748 Max , Performance Governor
2) Priority: 40
Temp > 27.8 degrees Celsius , 748 Max , 480 Min , On Demand
3) Priority: 50
Temp > 30.4 degrees Celsius , 748 Max , 245 Min , On Demand
4) Priority: 60
Screen off , 748 Max , 245 Min , On Demand
5) Priority: 70 <---------------This one may not be needed.
In Call , 748 Max , 245 Min , On Demand
6) Priority: 80 <---------------This one is here just in case.
Temp > 38.2 degrees Celsius , 480 Max , 245 Min , On Demand

With these settings, the Optimus will be at its fastest when you are using the phone infrequently and need the extra speed while out and about while also reducing the chances of temporary lag. Since the "Performance Mode" has such a low temperature threshold until it switches to a new profile, this reduces heat generation and power consumption when you are using the phone for an extended period of time, but still maintains most of the quickness and responsiveness of the phone. The "Screen off" profile allows for resume times with a low possibility of lag after the phone awakes from Deep Sleep Mode.

With these settings, I have noticed that applications move with more pep and the phone responds a bit faster to touch. That's not to say I've seen enormous speed improvements from these profile settings but that the whole Android experience is more fluid on the Optimus now. Also, I have not noticed any adverse effects from these settings as of yet.

I'm still testing these and refining the temperature thresholds. But, these profiles are working out well.

Interesting question! I am curious to see how others will respond. As I have said before, most of the attention to CPU clocking is dedicated to conserving battery life while giving a bump up when needed. High performance/Low Endurance is not somehthing most people seek, but I am intrigued as to how this plays out. And you really seem to know what you are talking about and looking for...

I should advise you that some confilcts with SetCPU have caused many of us to move to other alternatives, such as NoFrills CPU, where there are no issues with our ROMs.

I'm using CleanROM for Froyo. I always liked the stock Android look and just wanted the benefits of a de-bloated, overclocked Optimus. At the least, I can say that SetCPU works flawlessly on CleanROM with the picasticks kernel.

I want to see how far I can push the Optimus to get the most fluid and smoothest experience possible. I am what I consider an infrequent user. Some texts, a few calls, a little web browsing, a half hour of music....this is how I use my phone on most days. So for those times I do use it, these settings give me the best experience. If I use it more on a rare day, SetCPU will adjust the overclock settings to accommodate.

I would definitely like to see if anyone else has a significant change in battery life with these profile settings. Where I live, my signal is so terrible that the strong majority of my battery goes to the phone's radio, so I can't see if these profiles are impacting the battery in a major way or not.

I have always used the profiles (when I used SetCPU) for heat protection and battery conservation. I believe that that is all it's good for. I get the performance part from over/under clocking and governors. For the best performance, max out your cpu and use the Performance governor.

Just remember that at the end of the day, you're still using a 600mhz single core device in a world of 1.2ghz dual/quad core devices.

Yeah, even overclocking the optimus to ridiculous levels, I was still blown away by the speed of my new evo. Even with some amazing and wonderful hackery, hardware determines more than software in this case.

The Optimus is definitely under-powered. 600 Mhz is minuscule in such a way that even a 1Ghz processor makes it look like a Model T in comparison to a BMW. The SGSIII's Quad Core 1.4 Ghz processor (from what previews I've read) is so fast that the moment you touch the screen, whatever comes next instantly happens and lag of any kind is non-existent. The previewer could not find an application the SGSIII could not handle or have difficulty in handling. But, I live in the world of prepaid phones and budgets. So, it's the Optimus S for me for now (I like to gush over the best every once in a while. Can you tell?).

With these settings, the Optimus still cannot handle a game like Angry Birds without lag. But, it does reduce the stuttering the Optimus has occasionally to almost zero. What I'm mainly looking for with these profiles are a smooth, fluid OS.

ondemand 787/245, deadline i/o scheduler. nothing fancy.
also have a Quick CPU Overclock widget that can switch the governor from ondemand to performance as necessary.

This makes for some good reading:

xda-developers - View Single Post - [REF]Refernce thread for all kinds of things!

To be honest, I've taken to setting mine to performance and leaving it there. I haven't noticed ay real battery drain above and beyond normal.

Same here.

Interesting...I haven't used anything like SetCPU. I simply set the overclock to 600 min/864 Max with the Performance governor. I'll switch to Powersave if my battery needs charging. My phone seemed hellishly fast at first, but about a week later it was back to being a slow piece of junk...even overclocked. Is there any way to ramp up performance and keep it there!?

Oh...and the battery likely has to be replaced as it drains like mad now anyway.

You cooked your battery running at 864 the whole time. Performance keeps it there always.

I am surprised its only the battery that is cooked with those settings.

A lot of the "older" OptiS's could overclock to those high(er) speeds with just a few that couldn't break the 800 bar. Lately, it appears that it's the other way around.

Higher clock speeds isn't going to "cook" the battery. Drain might be faster (I haven't seen a huge difference between performance and ondemand), but I would say that the drain is probably due to ICS, not a bad battery.

 

[Pkt_Lnt]

My guess is the phone get hot always at full speed. Batteries do not tolerate heat well, it increases the discharge rate. That and high draw from the maxed CPU is what I mean by "cooked".

Actually, the only time the battery gets even slightly hot is when it's on the charger. But when it's on the charger, I've already switched to Powersave anyway. Besides, it drained pretty fast anyway, and that was before rooting and everything. It's even faster in draining now. In fact, it didn't drain so fast until I had gotten the OTA update to Gingerbread...I wonder...though downgrading back to Froyo (in order to root up and ROM up) should've corrected that...right?

I still haven't found how deep the damage that gingerbread did to the battery goes but I had the same problem as you so I ordered two new extra batteries the new battery lasted much longer than the damaged one I don't even use the second battery I ordered gingerbread did something to the battery and a replacement will do wonders for you
