Underclocking S III Mini?? - Galaxy S III Mini Q&A, Help & Troubleshooting

I cant underclock mine, anyone here suceeded underclocking their device?? Im trying to make my device 1000mhz max 200 mhz min when screen on , 600 mhz max 200 mhz min when screen off but how low i set my max freuqency it stills stays on 1000 mhz. I know power saving thing can allow u to underclock but the max frequency was only 800 mhz.

Try an app called on google play one power guard it works for me. Allows you to set your own custom frequencies.

use setCPU or nofrills

Doesnt work

Freeze the TwDVFS package in Titanium Backup, then try again. You will lose power saving mode this way, but you will gain control over CPU frequency.

Freezing the package doesnt have any effect for me. Using SETCPU, have general setting 1000/200 with governor conservative, scheduler noop, applying at boot and it works fine, have a great performance and a really good battery live but profiles i create wont be applied. Wanted to create a profile with lower frequencies at a battery level under/equal a value of 20% but no success for me. Tried with all governers incl. the powersave - but nothing changes. Of course rooted, with OXXAMB2 fw and stock kernel...

Thank you for the feedback, I'm actually surprised. I haven't tested freezing TwDVFS but its name and kmsg seemed to point out that it was in charge of breaking CPU profiles.

SetCPU best frequency settings

so I've been overclocking at 748800mhz, min and max, on the screen on profile which is perfectly stable. I tried overclocking at 768000mhz, min and max, and got random reboots approximately every 5 minutes. so, if I set the max to 768000 and the min to 748800, will it be stable?

Should be, what is your scaling set to? Try it with smartass or interactive.
it was set to performance, but ill try it on interactive!

Performance will keep it at the maximum all the time. If your phone cant handle the speed, it will freeze/boot loop until you change it. Try interactive and make a profile for when you plug your charger in, it drops down to 691.
What kind of battery life are you getting when you leave your cpu overclocked with both the min/max like that?
I typically do 245/710 for screen on but get 20-30hrs of battery life, is the battery hit not that much or are you just around a charger enough that you don't need to worry about it?

no. if your phone reboots at 768 it just can't handle the frequency. You should try clocking your min down a bit, like to 352 min screen on, it should help battery a bit and I doubt you'll notice a difference in performance. Also, if you apply the smartass governor it will do a few things your profiles do, so you won't need as many profiles. In the smartass gov, the max freq screen off is 352, and the min freq screen on is 518, so all you would need to set is a general profile like 245 min and 748 max, then the smartass gov will do the rest for you

It should be showing up in your governor settings. Should be the 2nd from the top (Right under Interactive)

I wouldn't worry about the website, just keep using that forum.
Is it better to just have one profile (like 710 max, 245 min) rather than two profiles, one for screen-on (528-710) and one for screen-off (245-352)? Also, is it better to use the ondemand governor rather than interactive or smartass?

I don't see smartass either. I'm running both the CMD kernel and rom. Is there a way to fix this?

[Q] No Frills or SetCPU?? Best suitable min frequency other than 100 mhz??

Which over clocking app is better No Frills or Set CPU?? Suggest other good overclocking app if there..
Which min frequency other than 100 mhz is better for smmoth functiong( not at the cost of battery).
I m on Darky Rom 10.2.2 EE
Dark Core Kernel 2.9.
There is no frequency better than 100 mhz if you don't want to lose battery. Common sense, please.

Best setting is not only turn cpu down. Display, auto sync,ect ect
Ok i was testing the cpu settings im on min 200mhz max 500mhz this is mindblowing got 6 hours screen on most of the time so yes very heavy usage and at the same time i was downloading at 200 plus kbs plus typing this and foing multi tasking gonna keep these settings for good

Min frequency trickstermod

Hello guys i just wanna have solution abt min frequency keep coming back to 1500 i cant set it to 102 ...is it a bug ? Im on iodak v7 kernel
Sent from my LG-P880 using xda app-developers app
I have the same it says it comr back but it really is 100mhz you can see it bij trickstermod info
Sent from my LG-P880 using xda app-developers app
I don't recommend using trickstermod, cause of very fast battery draining (paradoxal, I know). I had it set to 860 mhz max and 102 mhz min, all 4 cores, and in pure stand-by mode it drained 15-20% of batt with everything off, checked and re-checked, in around an hour or less. Devs' explanation was that the SoC probably kept the CPU at that max set frequency all the time. But... shouldn't TM control the frequencies? Isn't that what it's for?

What is the most extreme way to increase your batterylife?

The batterylife of my p880 is the worst ive ever seen.
Do you guys know some ways to extremely increase the batterylife?
Maybe a new kernel or something in the settings? Or an app?
Im running cm10.1 with the latest iodak kernel.
Sent from my LG-P880. Using xda premium.
set the powersave policy to max/aggressive/active, use smartassV2, conservative, lagfree or lazy as CPU governor, try using greenify, delete any apps you don't need and do NOT overclock
EDIT: also try flashing a kernel with battery life tweaks
Well, I use an app called battery saver (root). You'll find it in Play Store. It's for root users, so you need to be rooted.
What it does: Battery Saver (root) will change the system ROM configuration for better battery life. It won't cut off WiFi, mobile data etc while the phone is in sleep like other apps does.
Try it for some days, it should help you like it did for me

Undervolt 70 on all and under clock to 1300mhz,, greenify all unimportant apps, disable some stock apps. Set brightness 35% auto, Get you atleast 4.2 hours on screen time.

Underclock to 1000mhz no performance lose and better battery life, and this is maby wierd set your minum frequency on 200mhz 200mhz uses less power then 100mhz. If you dont believe me search on the internet

if you want to increase your battery life you should use a car battery ) but that is insane
also nvidia tegra 3 use much energy for the 4 cores so if you don't find a app to use only 1-2(1 on menu, 2 on apps or light games) core and only 4 on heavy games you are lost even if you use a extended battery, because op4x use all 4 cores all the time soo that's sad

I've searched the Interwebz and could not find any support for your claim regarding the 200MHz min. core frequency being more energy-efficient then 100MHz. Can you point me in the right direction?

Edit: here is the info for 200mhz
Q. "I'm going to set scaling min freq as 100 mhz because my kernel supports it. Hope there's nothing wrong in doing that."
A. Wait! You may want to stay away from using 100mhz during screen-off or screen-on states for three reasons 1) It seems 100 mhz uses more power than 200 mhz. According to tests, 100 mhz accounted to 1 W / GHz and 200 mhz to 0.7 W / GHz, when both the cores were online. 2) 200 mhz can finish same task faster compared 100 mhz and thus hit deep idle soon. 3) 200 mhz is the 'sweet spot' of frequency in SGS II. ie, the frequency used in the calculations based on the optimal energy to run (Ex: In Milestone it's 550 MHz). So , 'energetically efficient' frequency for our CPU is 200 mhz.
Edit 2: for a good govenor use conservative and use this tweaks:
Up_thresold 95
Sampeling_rate 120000
Sampeling_down factor 1
Down_treshold 40
Freq_step 10

I believe this occurs on dual core cpus.
Should work on quad too though.

51 mhz as min frequency? isn't that too low for the phone itself to function?
