SetCPU settings

Morning all, I am wondering settings people use with setcpu on their phones. Mine has always been set to ondemand, but wondered what the other ones do and are there any benefits?

Depends on the kernel actually... current trend is leaning towards ondemand, and so am I... I tend to put it to performance for Quadrant tests to eliminate lag, but that seems to be it...

Loving smartass governor since my battery stays generally the same when screen is off. Kernel has to support it though.

Cpu scaling question

Will there be any problems with my phone if I have max cpu speed at 800 or lower?
Sent from my SPH-D700 using XDA Premium App

No. Just don't expect enough of a battery gain for it to be worth it.
Texted while driving

I use my phone in a very hot environment so I just want it to stay cool.
How much will under scaling effect heat produced?

The term is underclocking.It might help, but CPU temperatures vary with each phone, the best bet would be to just give it a try.

K I'll try that
Thx for replying

If you haven't already, you might want to also install a widget that monitors vital stats, like temperature. I use one called TEMP+CPU Pro. It monitors CPU usage, clock speed, temperature, and available RAM and only takes up the space of one icon on your desktop.

I've been capped to 800mhz on a kernel that goes up to 1.3ghz for 2 weeks now. No problems.

Well if it makes your face smile, I run at 600mhz.

Seriously?
Do you get any lag?
I'm currently on EXT4, VisionKernel 1.0, deOdexed EC05 and when I clock down to 600 MHz, my Epic stutters here and there.

well i keep my phone at min. 200 and max 400 and i have no problems with it and the battery is great. u just need to b a lil more patient when its that low.

Are you referring to your screen off setting or do you run it at 400/200 all of the time?

What temperature is considered "overheating"?

I have been overclocking my CPU lately, sitting good right now at 1.2 ghz. I have it undervolted as well to prevent overheating. My question is what temperature do you associate with too hot? 100 F? more?
I dont like letting my phone get over 95 F, but im just curious to know what is considered a safe temperature range.
I cant directly measure my CPU temp, as that feature is not offered on our phone which really sucks, i have to go by the battery.

I have not the slightest clue but I would think you would go by how it feels in your hand and whether or not you can "smell" the cpu burning. I usually dnt clock it above 1.2 unless I'm gaming which is bad but I have it setup by a laptop cooler so it never overheats. Id say anything more than 90 would be pushing it.....

Not true put it like this our phones automatically shut off @ 122*F I go to 115*F when i play GTA 3 @ 1.5Ghz, but i can clock to 104*F just streaming music on WiFi.
So id say personally probably around 110*F+
Yes 105*F is hot but don't run it that high forever though.
But thats the battery, CPU stays fine so id say if your running 100*F+ For more than an hour than it might overheat??? Not completely sure but like i said everyday i play GTA 3 and get up to those temps.

Do you undervolt your cpu or run it on stock cpu voltages? I'm currently running samurai assassination and my phone always crashes if I undervolt it, and usually crashes when I run it at max voltages, but only when I overclock.
Sent from my SPH-D700 using XDA App

I would consider 114 f overheating, that's when I have setcpu underlock to 800 mhz

Used to but because i play GTA 3 now i dont if undervolt that defeats the sole purpose to overclock so i can play without lag, once you undervolt it decreases performance but however gains in battery life.

His epic is weird undervolting drops his preformance whereas mine increases preformance......
Sent From My Cyan Samurai

I would agree, 105, 108 would be ok but not for extended periods. Taking the back off usually cools the phone almost 5 degrees for me, but Epics are weird

Yes and has ability to set I/0 Scheduler plus setcpu reads wrong. And is outdated.

I'd say that everyday during the summer in Phoenix I'd be overheating as the daily temp rises to 115+ for weeks.

I do this too, for the battery anyway. If it overheats I uc. If I'm under %80 I uc to 800, %50 600, 30% 400

But not an option to Overvolt, and choose an i/0 scheduler. plus its a bit faster to use and works with other programs nicely

Wheatley Governor

Does anybody run the wheatley governor on there epics? When your charging your phone does it deep sleep? I noticed while I was charging that my epic deep sleeped while it was charging. I never seen that before that's why I'm asking...
Sent from my SPH-D700 using Tapatalk 2

I'm guessing your on cm10... that's a known "issue" it states it in the OP. Although on the gnex that is perfectly normal im told. I'm guessing something about the 3.x kernel that does it?
Sent From My Toro+ via White Tapatalk

Nah no cm10, touchwiz fc09 with samurai kernel.
Sent from my SPH-D700 using Tapatalk 2

I had pretty much the opposite problem that your having. I used to use the governor and my phone wouldn't ever go to deep sleep. Ever since then I've been using shadow and haven't had any problems. So maybe the simplest solution would be to switch kernels? Or even simpler, change governors?

Didn't get deep sleep because the cfq I/O is messed up.
Sent From My Toro+ via White Tapatalk

Its not really a problem. I just noticed my battery was lasting way longer when the phone charges while in deep sleep. I use system panel to monitor cpu usage as well as cpu spy. My setup is crispy clean 2.61 rom, I don't shut any syncs off. I just been running it with the normal samurai governor and decided to experiment with diff governors. In a normal day for me my epic would be at 25-30% battery level. With the phone deep sleeping and charging, on a normal day my epic is now at 50-60% battery. If anybody has the time maybe they can try the same setup and let me know if it does the same for them.

That seems like a good thing lol. I may try it. I'm gonna flash samurai now. I'm using thunderhawk tho. Ill try both.
And how do u know if it goes to deep sleep when its charging? With cpu spy right?
Sent from my SPH-D700 using xda app-developers app

cpu spy gives you the % of cpu use, system panel gives you a graph.
Sent from my SPH-D700 using Tapatalk 2

Yeah CPU spy should tell you if the "deep sleep" frequency is used.

Yeah I used to use cpu spy sometimes. Ill install it now. I just flashed samurai so ill see how today goes lol.

Is this cpu temp normal

I have lyapota kernel with undervolt but get this cpu temp. Is this normal?
Sent from my HTC One X using XDA Premium 4 mobile app

That looks extremely hot my friend, I have never seen mine that hot.
What was your phone doing to reach those temperatures?
What are your settings?
Which version of kernel?
Governor?
Voltages?
here's my temps
Using lm#17 pre aroma
-75 cpu undervolt
Even under full load I'm only seeing a maximum of around 50-55

Highest at 81°C is normal...it won't go pass that. Stock kernel capped at 85°C. When reach at that temp, CPU will be throttled to maintain below capped temp.
Just don't play heavy games while charging. Almost can fried egg with this phone. [emoji39]
