Hello, so here's my situation.
I'm on a Galaxy S4 Mini, running Lollipop 5.1. Everything was fine with my kernel, until i finally discover that it was acting weird..
I was usually setting the governor as conservative, with a maximum frequency of 1350mhz. The problem is that it is effective for the core n°1, but the core n°2 randomly gets online and jump all the way at higher speeds than the limit I've set. Usually 1400 up to 1700mhz. Which makes my phone running hot and draining fast..
I tried to change the hotplug settings to make only core N°1 online, but when I do that, the core runs at 100% (1350mhz which is the limit I've set) all the time.
The only solution I've found ATM to not drain my battery is to set the governor to powersave and locking it to 700mhz.. But it's a crappy solution since the frequency stays at the same state all the time with that governor.
-- EDIT --
Now I'm setting the cpu at 162 min and 810mhz max, with conservative. The big problem is that whenever the phone is awake, it runs almost full time at full load (810 mhz) and never scale down the frequency, just see the screenshot.. This is obviously ruining battery life. Why the hell is it doing this ? Isn't conservative made to use the lowest possible frequency as often as it can ?

Do you have any idea on why this problem is occurring ? Thanks

After rooting, unlocking bootloader, flashing Flex http://forum.xda-developers.com/showthread.php?t=1589034 my score is 2729. Runs real nice now.
Uploaded with ImageShack.us
Here is mine with flexreapers with his a100 tweaked kernal (so i can control the cpu max feq for power saving)
Only setting out of the ordinary i have enabled is Force GPU rendering (just experimenting with things to see how well it all works0

very nice, what app are u using to tweak the cpu? if you wouldnt mind posting what runs smoothest with no crash. basically a limit threshold. with crossix sd mod i only got up to 2744
I got up to 2830 using set cpu and performance governor with flex rf1. On my usual interactive it got a hair lower, 2790-2800 over 4 runs. Overall I seem to pull about 2750 averaged out. Rf1 isn't any faster then my 3.1 but I was already using the kernel in rf1 ( i think anyways, it was the second kernel he released for 3.1) on it, which did boost the score up about 300 points.
Edit: my bad I used antutu cpu master not set CPU

How do you turn on force GPU? No option like that in the menus. And does it cause any problems?
Its under developer towards the bottom of user interface. None that I've noticed so far, but I've only had it enabled for about 3 hours of use.

Hi,
The title says it all.. they are not working.. I am using ARHD with stock kernel.. each of them reset the values to default on waking up, reboot, or randomly, or an app pushes the on demand limit..
What I want to do is to limit the clocks to 640 ( or 10000 at least) on daily use..

This is a known issue with Tegra 3. At some low level, those values are governed by the CPU. Whatever you set them to, doesn't stick. Only governor and IO Scheduler sticks.
However, this doesn't mean that your CPUs work at the maximum possible frequency all the time. The Tegra architecture manages the CPU frequencies and you see a distribution of times at different frequencies.

EDIT: There is one thing you can do. Using SetCPU, under Advanced tab, you will see Powersave Bias (0-1000). Set to 0 on mine. If you set it to 400, your CPU will never go above 1000-1100 depending on how many CPUs are online. I am not sure if this will stick though. If you test it, let us know.
I recently installed "Need for Speed : Most Wanted" on my Xperia Ion . The first 1-2 mins are fine then the game becomes laggy and so unplayable.
After I close the game the cpu doesn't go higher clock than 810mhz (even while benchmarking) which causes a huge drop in performance and the device becomes a little bit slow.
My phone is not rooted so I can't change governer any idea ?

The board has an auto downlocking feature that turns the clock down to 810 Mhz when it heats too much. Safety vault, so the chip doesn't burn.

Because the system might be less loaded, or less RAM used. Dunno. In JB on S it runs almost without any problem

Hi guys! i have a Lenovo Vibe Shot Z90A40 bought a week or so ago, which i updated to Marshmallow via OTA update but that update didn't satisfy me and have some bugs including a major issue of Battery drain even on Standby/Idle.
All cpu cores are running at 990(1st 4 cores)/800(2nd 4 cores) frequency all the time even when on Phone is idle.
i had tried Reboot, Cache Clear, Turning off wifi scanning etc, even Factory Reset, but the problem still persisted.
So, ultimatly i downgraded to the Stock firmware Z90a40_S240_160119_ROW Lollipop 5.1
but now the problem still exists. Battery usage shows the CPU as the biggest battery drain factor.
I have added a screenshot of battery usage from CPU-Z app. please check it

Now what should i do now. i am tired of this abnormal behaviour of battery.
P.S. i have another XIAOMI NOTE PRO which has the same octacore processor. CPU-Z shows its 4 cores are running at 200 to 250 frequency and other 4 cores are stoped when the phone is Idle/Standby
P.S.S. if any other user have this phone with stock firmware 5.1 please share your cpu core stats from CPU-Z or some other app like that.
To be honest, I had a such problem, after upgrading till Android 6.0 (MM), after that I started to search the solution in the Internet. Didn't find. But, about month ago I installed root on my phone and installed an app "Device control" via Xposed where u can change min and max freq of the CPU. There u can also change the type of governor(idk how it's called, Im russian, sorryXD) like interactive\ondemand\powersave and etc.
Howdy...
I've been wondering how the Samsung S9 with Snapdragon behaves when throttling.
it's very easy to test... just run this app called CPU throttling Test and take a look at Temperature, Clock and Performance.
This is a Screenshot from my Sony Xperia XZ2:

}
You can clearly see the Temperature reaching a critical point and the Performance dropping, while Frequency stays at the same 2.8ghz.
Here we have a OP 6 which does show the same behaviour... no Frequency Limit!
Looking at the SD835 Essential Phone:
or the even older SD820 HTC 10:
We do see a CPU Frequency Limit on both devices.
So... is this Max Frequency yet still reduced Performance a Snapdragon 845 thingy?
Simply do the Test for 2-5 minutes (until throttling becomes obvious) and we will know.
P.S going to Options and chaging Threads from 20 to 7 might totally change the behaviour of this test!
P.P.S Go into Options and correctly set Thermal Zones! If you don't know which nr is what... Terminal / ADB shell "for file in sys/class/thermal/thermal_zone*/type; do echo "$file"; cat "$file"; done"
Greetings,
Haldi
Somebody made a video with 3 SD 845 phones, but he got higher performance, did you change number of threads from default 20 and where phones cold when you begin testing?
I can't post a link, just search "OnePlus 6 vs Sony XZ2 vs Xiaomi Black Shark" on youtube.
