I need help figuring out if I am using the right files to read the temperature
I use this one for overall CPU temperature /sys/devices/virtual/thermal/thermal_zone3/temp (mdm-core-usr)
and these for each core
/sys/devices/virtual/thermal/thermal_zone7/temp (acp1-cpu0-usr)
/sys/devices/virtual/thermal/thermal_zone8/temp (acp1-cpu1-usr)
/sys/devices/virtual/thermal/thermal_zone9/temp (acp1-cpu2-usr)
/sys/devices/virtual/thermal/thermal_zone10/temp (acp1-cpu3-usr)

What are good settings for the CPU when the screen is off and others?
Sent from my HTC Liberty using XDA App
I use Screen On at 806mHz and Screen Off at the lowest setting, conservative profile. It works well.
Both minimum and maximum are set to 245 for screen off? I want both performance and battery. I have my regular CPU set to 787 and 245.
Did you just answer your own question?
I think battery and performance dont really go hand in hand. I have screen off 245.
Give a little, take a little.
I wouldn't recommend using set CPU, there is still conspiracy whether it drains the life of your phones processor or not. I am leaning towards the validity of this research. Of course this is your choice, but be warned.

Huh? This is so easily testable. Leave your phone idle overnight without SetCPU, then with SetCPU set to underclock at 245, compare battery level in the morning. It is a basic law of physics that the power consumption of any switch is P=CV^2f, where C is the capacitance, V is the operating voltage and f is the operating frequency. Any CPU is a large collection of switches, lowering the operating frequency will always reduce power consumption unless the overhead of dynamic adjustment consumes more power.
Along the same logic if you overclock the CPU you WILL get more battery drain, guaranteed. As someone said earlier, power and performance are inversely related for any fixed configuration.

He said drain the life of the phones processor, not battery. I think he's saying shortening the life of the processor...I may be wrong.
did you guys also know they faked the moonlanding?
srsly though...set cpu is good stuff. if you think it drains the processors life, why not ask?
When you are not using your phone srt it to powersave 255 MHz and when you will use it. Set It to on demand 806 MHz

Simple question.
My freq now is 633 mhz..still will it shorten the life of my cpu???
Or higher freq and I mean not just for gaming,for everyday use.
Its mainly cuz of 360 launcher.
You need some higher freq to get the smooth look.
So???
Well, I've been using Overclock since the Day overclock came out..
And i have no damn problems .. CPU is still working Great!
And just to let ye know its clocked on 768 MHz ;D
Just overclock it Dude..
Your x8 will be Okay
But if u kept using it for long periods..
it might endanger Your CPU
Also be careful not to fall into a bootloop .. uncheck the Set on Boot option ..
check if it's working alright on 768 .. then check the Set on boot..
I have GDXv22 with [email protected] . .

Overclocking by 33MHz isn't dangerous, that's very mild.
In General - the more you overclock from the specified values (in case of the X8: 600MHz) the more heat you produce and the more you push the chip to the bleeding edge.
In short: Every integrated circuit has some headroom for overclock as the manufacturer specifies the clock rate at an safe value and not at the very bleeding edge where variances in the chip making process could lead to too high yields because they don't run stable with the clock frequency. In general you don't do your electronics a favor when pushing it too far. 700MHz+ will surely shorten the life span of your phone, how much would need to be seen as there's no real long-term experience.
Wow thanks guys.
You see after some thinkig it aint the cpu freq that is slow.
I set my low freq when in sleep on 245 so the phone is slow on waking up.
When you set it on high the phone will respond better!
like PC, when overclock it may reduce processor life
any clock reduces the life of your cpu. the higher the clock rate less life cpu
Guys does anyone know if there is a way to control the Cpu / Gpu throttling on the Xperia SP on stock rooted roms?
XSP still needs development since its a new phone
Try doomlord's kernel if your looking to overclock your cpu. cant tell about gpu as i havent been able to get its setting through overclocking apps..hopefully upcoming months are gonna bring better kernels n mods

I don't want to overclock the CPU or GPU.
what i wanted was to set the temperature at which the CPU throttles the GPU and CPU,
as I noticed it throttles them way to early and causes performance to drop,
i've found a bunch of files in system/etc ...
thermald.conf
thermald-8960.conf
thermald-8960ab.conf
which most likely have the temperatures set in them, just dunno if they are degrees C or farenheit and it isn't clear which refers to which cpu speed either,
was hoping someone can help me out here ...
regards
So, I overclocked my CPU frequency to 1836MHz and my GPU frequency to 450MHz and after playing a game for like 10mins, my phone gets really hot. I know its normal but I would like to ask, did I overclocked my phone too much that it can destroy my phone? And what is the overheat temperature for my phone(HTC One)? So I can monitor it.
Thank you

Yes its possible to permanently damage your phone if your overclock is too much aggressive or your phone get to hot. Every chip is slightly different so you'll have to test your phone for each frequency steps you do. Like a computer, you should start overclocking in small increments till you reach a maximum stable config and then reduce it a bit for safety. And always monitor temperature, over-temping is your worst enemy when overclocking.
For the max temp question I don't really know, you might want to check qualcomm site for max safe cpu temps. Don't forget some other components doesn't like high temperature. Semi-conductors components life are reduced in high temp conditions and generally, lithium-ion battery doesn't like high temperatures...

So basically, overclocking can really destroy my phone? So, i guess ill just switch back to the stock one. Thank you

That overclock is not going to hurt your phone but the temperature can if it gets too high which can happen at stock clocking. I keep my phone's cpu at 1.134 Ghz and games run great with minimal heat.

Found the information about the temp here
I had lag in some games solved this with resurrection remix and kernel M5. My question now is like a setting to have no problems with overheating am using min 300mhz ~ 1.4GHz is left with a high temperature 60 ° / 64 °(playing real racing 3) is safe?
thank you

Moving to a CM rom that doesn't have a CPU temperature throttle built in will give you faster perormance in games.
It's unlikely that you will damage the CPU with excessive gaming, but you will shorten the life of the battery. I thought I read somewhere about extreme temperature permanently changing the screen colour, but it might not have applied to the Z3c.

Not need the kernel m5? cm tested only with kernel m5, I will do a test only with the CM without the M5 kernel.
Thanks for the help

Heat is bad for electronics period. Phones aren't made to withstand long sessions of gaming as it does not have a decent cooling system to go along with it unlike gaming built cpus which have fans and liquid cooling to keep temps safe.
50-60 Celsius CPU temp for a phone is safe, you should get worried around the 70-75 Mark since the Phone throttle Temperature by default is around 80. I suggest playing in a well ventilated or an airconditioned room to keep those numbers down. You could also use a better governor for gaming like ElementalX or Lionheart and change it when you aren't gaming
