I want to over clock my HTC Desire using Set CPU
What should my max over clocking be , and what temperature should my CPU run at to be safe ?
I'm currently using the RCMixHD kernel.
Depends on your kernel.
Also, li-ion batteries are designed for use around 20c-60c, but as it goes past 40c, I think it has higher discharge rate.
Depends on your phone & kernel combo - 1113 Mhz is stable for the most of the people.
I suggest playing around with and test it - 1113+ is OK for some, but if you'll get reboots and the phone gets hot, then it is not recommended.
Also if you are OCing, you'll get more power, but worse battery life.
wont it consume more battery ??
I have Coutts 2.6.38 kernel and it allows me to underclock to 128MHz and 1190MHz overclock and I use ondemand since games don't like other governers. The underclock is bloody great to have as it consumes bugger all battery life and kind of balances out the overclock. However, as nagypapi said, you might not be able to get these speeds since your phone might get hot or reboot. I think people fail to realise that not all devices are the same and what works for one person, might not work for another.
Max. clock should depend on kernel support(if the kernel supports it, then that's your maximum clock). As for temperature, I have a profile on SetCPU which down-clocks the CPU when the temperature reading goes above 36 degree celsius. All other times it works between 806MHz-245MHz OnDemand.

Sort of goes without saying that the higher the CPU cycles the more battery juice your phone will consume and the quicker your battery will drain. I use GingerVillain which supports speeds 128Mhz - 1113mhz and using Richard Trips 2.0b OC kernel (based 2.6.37.4) seems to keep battery alive for a good 24hrs. If it's any help my SetCPU profiles are as follows :
On Charge : 128-1113 performance govenor
Sleep/Standby : 128-576 conservative
Battery < 100% : 128-998 performance
Battery < 75% : 128-883 ondemand
Battery < 30% : 128-652 ondemand
Failsafe Temp > 45.1c : 128-768 conservative
Seems to give me a good balance of speed and battery life, but would be interested to hear from anyone else that thinks my settings are wrong, always looking to improve my phone!

I would like to try this settings, but could you please also add priorities for each setting?
Also what is your main governor? (when you startup SetCPU)
Other thing i dont understand why people use such high cpu freq for battery charging (when its charging and im never using phone then, isnt it better to put some low freq. and power saving profile?)
Same about Standy/Screen off.
128 is too low, it makes my phone slow, 245 is better IMO.

set 245 for screen off only ... Its not meant to make your phone quick its meant to conserve battery lol

I know it, but weird, when I set the lowest value to 128, my phone's reaction become laggy, but 245 has no such problem. Maybe it's affected by kernel or rom.
sorry for my poor english
I know some roms/kernels have issues with dropping to 128 but my rom seems quite happy with it. I use higher CPU on charge and with battery above 75% to give me the performance when I have the most charge. When my phone boots it will adjust CPU according to battery life or charging profile. The settings seems to work fine for me although battery does drain quicker when I have it fully charged but that's my own fault for setting the performance govenor when I have high charge!

I'm using your way! thanks!
No!
Using any CPU frequency that is not default ( underclocked or overclocked ) requires testing and manipulating the various variables. The CPU needs to be in sync with the GPU and the other parameters. Needs modifications in the kernel itself. The device is not made to run at those frequencies. You will burn your device, sooner or later.
Seen a lot of conflicting comments stating using smartass governor means there is no need for profiles to be setup and can actually be detriment to the battery life and speed of phone.
Is this true or could I benefit from setting up profiles to get my usage optimised.
Below is a quote which will explain you everything about smartass governor
From it's developer:
"smartass governor - is based on the concept of the interactive governor. I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies. Smartass will also cap the max frequency when sleeping to 352Mhz (or if your min frequency is higher than 352 - why?! - it will cap it to your min frequency). Lets take for example the 528/176 kernel, it will sleep at 352/176. No need for sleep profiles any more!"

A couple weeks ago, I installed SetCPU to help with battery life. It did great! But, I didn't see the amazing improvement that I thought I would.
So, I did some research and found out about Profiles. Profiles are settings that you can make that will be applied when certain conditions are met.
Below are the profiles that I have created on my Nitro. I have seen 11 to 12 hours of medium use from my phone with these settings. If you have any suggestions on changes, please let me know. I'd like to find the absolute best settings and share them for everybody.
Profile Name: Screen Off
Conditions: Screen Off
CPU Max: 384Mhz
CPU Min: 192Mhz
Governor: powersave
Priority: 90, Exclusive
Profile Name: Charging Any
Conditions: Charging Any
CPU Max: 1512Mhz
CPU Min: 192Mhz
Governor: ondemand
Priority: 85, Exclusive
Profile Name: In Call
Conditions: In Call
CPU Max: 810Mhz
CPU Min: 192Mhz
Governor: ondemand
Priority: 80, Exclusive
Profile Name: Battery <= 10%
Conditions: Battery <= 10%
CPU Max: 594Mhz
CPU Min: 192Mhz
Governor: conservative
Priority: 75, Exclusive
Profile Name: Battery <= 25%
Conditions: Battery <= 25%
CPU Max: 972Mhz
CPU Min: 192Mhz
Governor: conservative
Priority: 70, Exclusive
Profile Name: Battery <= 50%
Conditions: Battery <= 50%
CPU Max: 1242Mhz
CPU Min: 192Mhz
Governor: ondemand
Priority: 65, Exclusive
Profile Name: Battery <= 75%
Conditions: Battery <= 75%
CPU Max: 1350Mhz
CPU Min: 192Mhz
Governor: ondemand
Priority: 60, Exclusive
By setting the profiles base on battery percentage like that, you are sacrificing the speed to improve battery life. It works in some cases but has side-effect in many other cases:
- Firstly, for some tasks that requires high CPU, apparently you need more time at lower speed, so power consumption for CPU is the same but more power needed for longer screen on -> worse battery life
- Secondly, the more profiles you use, the longer it takes for SetCPU to decide and change CPU speed, so the responsiveness is lower
For you screen off profile, if you use powersave governor, your CPU always runs at min speed, so setting the max speed at 384 MHz is meaningless.
For me, the only profile I use is the screen off profile with min = 192MHz, max = 432MHz, governor = ondemand, so that my phone will wake up faster when there's a call (otherwise you will have to wait a little bit before you can sliding Answer/Reject)

I haven't seen any responsiveness problems... And I'd actually like having a phone that I don't have to charge ever 3 hours over one that is unnecessarily fast.

His point was that scaling your CPU back so significantly isn't necessarily going to give you better battery life, and may even make it worse. When the phone is running at a slower speed, it takes longer to do certain things, which means your CPU/screen will be turned on for longer. Of course it entirely depends on what you're doing on the phone.
I think you might get just as good battery life by using interactive 1.2GHz all the time. People assume governors like interactive will destroy their battery but you'd be surprised.

If you have to charge your phone every 3 hours without SetCPU then I suggest you buy a new phone or new battery rather than playing with SetCPU

I don't do much with my phone in the way of heavy gaming or video watching. I am going off of the last couple days of having SetCPU enabled and getting almost 15 hours of medium use out of my phone.

It was an arbitrary number.
Does anybody find this kind of post meant to make peoples phones better helpful? It seems like every time I post something that I personally have found to make the Nitro even more awesome gets a tone of comments basically telling me that none of it will ever work. I'm sure that if people would just try the things I post, they would be happy.
my setcpu setting-> uninstall
i found it did more harm than good. jd ultimate handling screen dimming&wifi with simple ondemand gov works much better for me.

That what I've heard also... But I found that JD ran my battery down in about 6 hours without me even touching it one day.
If you have any suggestions on settings for it, I'd love to give them a try.

yeah, i guess it's diff for everybody, just like the roms eh, some get great batt perf on 1 and sucky on another and someone has exactly opposite.
anyhoo, my jd ultimate settings are
Status
advanced profile
graphical notification->quickbox
Controls
wifi enabled->wifi preferred
brightness min 20% mid 45% max 150% (gotta get the most of this screen in the sunlight!)
light sensor fast
cpu min 192 mid 918 max 1512
governor ondemand
schedules
none, i also turned off night schedule as i have the phone plugged in during those hours.
triggers
Apps enabled
Configure->configure apps allow on during screen off->pandora
Location enabled
****************i find it makes a world of difference to give jd =>3 days to get it all right.
make sure setcpu is out of the way as well.
In rom control > cpu frequency?
What value have i set on min and max?
What type i have to set on governor?
What type i have to set on IO scheduler?
All setting cpu freq depend on what?
[ROM][AOKP][JB][RC]ARC S[Build 5]
[KERNEL][FUSION v3.7]
Have min and max set as the highest or 1.4 . set governor as performance, and have 'noop' as IO. Of course, the frequency entirely depends on what you want from your phone - best performance with high battery drain, laggy as hell performance with best battery life, or somwhere in the middle

So what value have to i set? Depend on ?
[ROM][AOKP][JB][RC]ARC S[Build 5]
[KERNEL][FUSION v3.7]
the higher the frequency/value, the faster and better performance your phone will have. So depending on how slow/fast you want your phone, set the frequency/value to the appropriate/corresponding level of performance
Basicly you have to experiment with the cpu freq in order to determine the best freq for your desire (gaming,smoothines,battery drain)
As for guvernors - Performance will always keep it at max freq so it drains ur batttery like hell
- Smartass will use lower freq and less the max freq so its the best for battery life and smoothines in my experience.
If you used search you would have found -> gouvernors info
Gouvernor Infos
AS for I/o sched -Noop has the best ratio for perfo/batt life.
Performance sheeet comparison of sched and guvernors

Better set Interactive because performence eats battery
cpu
what the best cpu ferequency for arc s?
for bettey battery life?
what is governor?
what is i/o schedual?
ihave a problen in set cpu
i set the cpu for an app , and when i go to app and after close the app , don't back ferequency to values that i set in the main screen
and the ferequency set to maximum
I am using Paranoid Android 3+ (the latest Alpha 5 version) and use the kernel that came with the ROM. I posted a couple pictures of my problem. The standby time is great. But I feel I have a problem because once I use my phone, the battery drains at a fast rate (hence the small screen-on time of 33 minutes). I dont believe the battery should be low given the low screen-on time. How can I check what is killing my battery? Im not sure if this info. is important, but I flashed AK Rubik kernel then Franco, but reverted back to the Paranoid Android kernel. Could that have affected my battery in a negative way? I would also like to know of some good kernel tweaks, ad CPU control options I should use. I'm using ROM toolbox and I have a profile set to "Charging/Full"; Gov: "Performance" 920 MHz Max, 350 Min. Priority set to 50. And another profile set to "Battery <25%"; Gov: "Powersave" 700 MHz Max, 350 MHz Min. I/O scheduler for both is "cfq".
Anyone have any ideas on what I can do to improve my battery life? Any help would be greatly appreciated!!
