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.
Hi guys, I'd like to ask you a question about undervolting. I'm using Andromadus Beta 5 at the moment and it's working well enough for me, but under my rather heavy usage, my battery seems not to last that long. I'm already on the latest .19 radio and my CPU is clocked at 1GHz max with smartass v2 governor and 768 max conservative screen-off (with SetCPU).
I remember that when I was on GB (CM7.1) I used a slightly lower cpu voltage and everything was fine, so does anybody know if it's actually possible to edit the voltage table or whatever in order to UV my CPU on Andromadus?
Thanks in advance!
Don't bother, the Andromadus kernel already has somewhat low voltages. That said: https://twitter.com/rmk40/statuses/170239362020282369
Thanks for the answer. Actually the fact that undervolting the CPU doesn't bring any improvement in battery life seems a bit strange... I was hoping at least in a 5% increase. I also have to say that I have 3G and data always active, so probably that's the main reason of my short battery life.
I'm wondering if anyone's undervolted and to what values.
I'm also wondering waht the deafult values are and if they change per kernel.
Is there a way to disable SetCPUs undervolting settings?
Has anyone improved battery life with profiles? On the Eris this was the only way to get usable battery life.
Or not. I gave up undervolting after I actually compared battery life at stock values vs undervolted (on my old phone, sgs4g) and discovered it does nothing for battery life.
Edit: undervolting "might" marginally increase standby battery life, but considering how good this phone already does... it certainly won't increase actual screen on usage.

Depends how low you under volt. Got more battery life, maybe about an hour, after finding optimal battery life on my gfs Gnex.
If you don't under volt correctly, of course it won't improve battery life.
From my sexy white, Nocturnaled HTC One X
If you're not overly comfortable with undervolting, then using one of the many kernels with Smart Reflex will do a mild undervolt for you. If you are comfortable, then the only way to find numbers good for your phone is to try and test. I tweaked mine down to the point that I was occasionally getting hot boots when the screen was off and media was playing. Tweaking the numbers back up added the needed stability. Even little things like kernel or ROM revisions can change what voltage is or isn't stable. Another example is that when I updated my Jellybro CM10 version the other night, along with updating leankernel from 4.1.0exp3 to 4.2.0, I had to increase a few of my voltages to avoid hot boots.
Just for example numbers, here are mine:
Code:
1350MHz -- 1200mV
1200MHz -- 1150mV
920MHz -- 1050mV
700MHz -- 950mV
350MHz -- 825mV
These numbers will vary from device to device and even between ROM/kernel combinations, so don't use them as hard fact.
Thanks. On a phone like this it might not make a huge difference but on the Eris (Where stock battery life could sometimes be 6 hours if you actually used your phone) an undervolted kernel with setcpu could turn those 6 ours into 48.
Thanks Cilraaz, I'll try those voltages out and benchmark a bit to see if they're stable for my system.
Two things I can say for sure:
1. you will have very limit battery gain by undervolting with Gnex, no matter how low you try.
2. undervolting will bring some stable issue if you get too low, like lose signal and reboot.
I am using Kernel Franco GPU 384 Stock rom on my 4.1.1 and did undervolting
Current configuration:
384Mhz
950mv
------------
729Mhz
1050mv

1036mhz

I did not change the frequencies of overclocking, because I'm not using them.
I felt an improvement in battery consumption unless the unit is heating up.
Just curious - what kind of profiles are you using? I have a "Screen off" that's 350min and 700max. I figure that's fast enough f someone calls me.
I've read many times undervolting isn't worth it.

I'm using the following with SetCPU: default (1350MHz-350MHz), charging, CPU temp > 64, and battery < 35%.
If you're using a kernel and governor that support hotplug, then you likely don't want to use a screen off profile. The combination of the two can tend to cause sleep-of-death or hot boots.

Most people don't want to spend the time to do it right.
I'm actually not used to the new kernels. I haven't messed with my eris in about a year and back them there was "smartass, on demand, performance," and some other one that clocked down instead of up
Can you explain th escreen off profile causing issues? I don't even know what hotplug is lol I've been out of Android for a long time.

Hotplug disables one of the CPU cores when the screen is off. Some governors, like hotplugx, will also attempt to disable a CPU core during periods of low CPU usage. For some reason, this combined with a screen off profile can cause some problems. I assume it's because of the "screen-off-max-freq" that Imoseyon mentions in the quote below.
Personally, I prefer the interactivex governor with leankernel by Imoseyon. From his kernel thread:
With interactiveX V2 (for gnexus), things are a bit different, since gnexus has built-in support for screen-off-max-freq for all its governors. I took the new interactive code in gnexus, added early_suspend support (screen off/on trigger), and then added logic to the code so the governor uses the phone's built-in hotplugging capability to turn off cpu1 when screen is off (and then turn it back on when screen comes back on). Cpu1 goes offline entirely - no idle, no sleep.

I think undervolting helps - my phone is running 728 - 1228 using the interactive governor, with voltages of 600 mV, 700 mV, and 800 mV (728 MHz, 1036 MHz, 1228 MHz respectively) and I haven't had any issues so far. I know there are some reports that say undervolting doesn't help much, but those are when people undervolt by like 50 mV, whereas here I'm going like 400 mV under lol. (Yes, smart reflex is off).
Thanks Cilraaz. Good to know.
So turning the screen-off profile could improve things? Honestly, my system does fine at 350mhz with screen off. Turning a core entirely off would probably help though.
If I use hotplugx governor that would disable one core when the screens off, right?

Hotplugx will disable a core when the screen is off or when there is low system load. Depending on your kernel/governor choice, other governors may do it also. On leankernel, for instance, interactivex will disable a core when the screen is off, but not on low system load.
Ok, thank you.
I haven't done any comparisons of before/ after since I undervolted/ underclocked first thing. But I was browsing for hours while listening to music while talking to a friend with GTalk. talked for about 1.5 hours with someone, Left it on overnight (10 hours), woke up, used it to talk (voice to text) to someone via GTalk, and it's 3:25PM right now and I still have a fair amount of battery life left.
I'd heard mixed things about the battery on this so I'm happy.
My voltages:
1650: 1300
1520: 1250
1350: 1175:
1200: 1125
920: 1000
700: 925
350: 900
I stress tested each one without a crash.
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.

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

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.

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.
Am using AndroidRevolution HD and PopcornKernel for the maximum battery life.
I am using agressiveX governor.. its basically conservative with tweaks and hotplugging
At first I used franco's updater app to change my cpu min and max.. this app did not have a scheduler option but when i used SetCPU i chose deadline.. my batt life became a bit shorter.
I had 300+ min and 700+max. Was running smoothly and got about 6h on screen time thanks to both the rom and kernel being built for batt life and the conservative-like governer.
So basically i have 2 questions:
Which scheduler do I use to maximize battery life and Why is it when my device is off screen it runs out of batt so fast.. could it be due to hotplugging or the low cpu speed i have?

What are your battery stats like while the screen is off? If the phone is being held awake, you have an app that is constantly waking the phone up. Next charge cycle, provide a screenshot. I don't know just how much different schedulers help in terms of battery. I've hopped between noop and deadline and never really noticed a difference. Best bet would be to try each one. YMMV because my usage pattern may not match yours.
I have checked with CPUSpy and yes my device is entering deep sleep.. i wanna know if such a low voltage affects my phone sleep since i have hotplugging enabled
