What does Power Saver Conserving CPU do?

I've enabled the converse CPU option in the power saver menu and I'd like to know what that does exactly. Does it just lower the CPU's clock speed? What are the best apps to monitor CPU usage?

Lowers your cpu freq tot 1.1ghz, that's all

It lowers your CPU speed to a maximum of 1.1GHz but it does not lower the GPU speeds. For games that aren't that CPU intensive, you can still play totally smooth with Power Saver on

It does a few other things as well depending on the options that are enabled in settings power

Yea I got that.
It's just I got the phone a few days ago and still getting use to all the settings.
I move from an s2

Does anyone know a working CPU frequency set/limit program?
I want to limit the CPU to 600MHz or even 400MHz during driving because I want to use it as a blackbox and record everything. If I can limit the CPU, it won't heat up as bad.
I tried setCPU, antutu cpu master, no-frills cpu control, and everything doesn't seem to stick. I currently have it in energy saving mode, so it's 1100MHz.

The HTC One has an issue with frequencies sticking, it's because of the permlock. You could either flash a custom kernel or you could use setcpu and use the disable permlock feature, which I haven't tested, but it claims to allow frequencies to stick.
You'll need root for all this ofcourse

take it off powersaving mode and you should be able to adjust it

Tried that, didn't help. As soon as I close the app or switch to another app, it goes back to 1.4 GHz/1.6GHz.

See where it starts going down in 25mV intervals, do that all the way to the bottom (the app there is Kernel Tuner). The top two frequencies can be dropped by 25, but from there and any lower on the top two and you'll get an undervolt forced reboot. Some of the low end freqs might be able to go a bit lower than what my scale gives, you'll just have to test yourself since every phone is different in the undervolt department. And do not set it to activate on boot until you've pushed your phone a bit and know those voltages work. It is possible to undervolt brick a phone forcing you to do a factory reset to remove the saved undervolt values (or a full rom install if you save bad undervolt settings in an init.d script).

so are these values arlready lowered or are these stock values ? and which rom were these settings made ?

Rom shouldn't be an issue, this a kernel feature to undervolt cpu.

Guessing at the rom....probably PAC 4.4, but like Techno said, that really doesn't matter. And those are lowered.

Thanks, mate! It was trial and error, wasn't it? Is it too noticeable the battery save?

It doesn't make a big difference for me, but you should just try and see it yourself.

CPU Boosts to the Highest Frequency When Switching Apps in RR-OS

Recently I noticed that all CPU cores will suddenly boost to the highest frequency for a few moments every time while opening/ closing/ switching apps in the RR-OS (as well as in Lineage OS), and then it will gradually go back to lower frequency.

}
(This is the moment when I lauch the Settings app and press the Muiti-tasking button. All CPU cores boost to the highest freq regardless which CPU Governor I set.)
This issue consumes a lot of battery (up to 1130mA). However, this will never happen in the stock MIUI ROM. I have tried using different CPU Governors but this still happens.
So, is there any method to disable this CPU boosting feature to conserve the battery life?
Thanks!
(Logcat attached here when I press the Muiti-task button)

04-24 13:43:19.148 9563 9839 E wifi : Ignoring invalid tx_level info in radio_stats

Even though if what you say is true the mix still has a very good battery life and what I would want to be able to tweak is, as you say to have a better CPU management when it comes to light or heavy work loads, the use of a single CPU on light tasks and full throttle on heavy tasks, I would also like to be able to over clock my CPU's to 2.5ghz if possible.

As far as i know, both OP and Over clocking is about the kernel. In my opinion thats why cpu boosting that the OP mentioned is making the RR so smooth, which is very familiar to me from Exynos kernels on Samsung. One of the greatest kernel developers @UpInTheAir who built a lot of great, overclocked, optimizable kernels which let you play with governor tunables and select which frequencies the cpu can be boosted and so on. So if there are proper kernel sources and @pappschlumpf would dive into the kernel job; there would be a good kernel. Hopefully in the future..

Question Anyone tried KonaBess for GPU OC/UV?

Hi,
does anyone tried to optimize the gpu of the SD888 Soc via KonaBess?
i found a post with a list of changes a user made. https://forum.xda-developers.com/t/...-root-and-konabess-app.4275089/#post-85555809
So i used the same settings to maybe save some battery.
I'm not a phone-gamer at all, but i tried to OC the gpu a bit. Not because i need it, but i wanted to see what's possible.
850mhz is working fine. If I set 860mhz even with higher voltage level (LEVEL_TURBO_L2) the phone won't boot. So i stay with 850mhz.

If youre interested, i exported my settings (150mhz added, UV, OC to 850mhz), which can imported in the konabess app.
Via app you can import/export settings and save your vendor.img. If the boot fails, flash your backuped vendor.img via twrp and the phone will boot again.
Maybe we can gain some more perfomance or better batterylife via undervolting.

I have lowered the voltage on my 11T Pro using KonaBess.
If the voltage on the high frequency side was reduced too much, the drawing of the 3D bench collapsed or could not be started.
Also, if I reduced the voltage too much on the low frequency side
The home screen would freeze or collapse after startup.
Therefore, it seems that the GPU voltage is actually being changed.
In the default state and after lowering the voltage
Wild Life Extreme Stress Test, respectively.
the score for the lower voltage was
all exceeded the default score, suggesting that the lower voltage
throttling is suppressed.
We have been using the system for several weeks in the low voltage state.
The operation is extremely stable.
Of course, there are individual differences in margins, whether for OC or lower voltages.

@cyphone
Sounds great. Nice that you tested more then me. Did you noticed some improvement in batterylife or does the phone feels cooler?
Why did you used the app at all? Just out of interest or did you aimed for something special?
Can you share your stable settings and/or list your changes, to let me and others try the same settings?
EDIT: Okay, seems like he won't respond. Sad.

Question How to increase the clock speed of the GPU?

On the stock Chinese ROM, I noticed that the GPU is locked to 305 MHz. Can we change some settings to increase this? For reference, the GPU's max speed is 650 MHz.

I'm 90% sure this works. Search for "manage my games" in the settings, and check your games. That will boost the GPU clock speed. With the stock rom you can use the time widget with cpu/cpu clock speeds, and if you open a game and then go back to the home screen you'll see the gpu/cpu at a higher clock speed.
Oh, there's also a bar at the top when you're playing a game and it shows cpu/gpu clock speeds, temp and fps. Even at the stock clock speeds I have great game performance.

I already use Legion Assistant but did not see the GPU increase its speed. I guess the game isn't supported, or the increase in GPU speed won't help (the game relies on CPU power more than GPU)

the cpu and gpu increase in speed. Even if you choose beast mode you don't see a cpu increase?

The CPU changes its speed but the GPU is constant at 305MHz, even in beast mode. I guess the game doesn't need it. I haven't tried other games sine I only play one android game right now, and the tablet's other uses are for videos and manga reading.

Ok, what if you turned on disable hw overlays in the developer options?

Didn't work. Anyway I've tried another game and the GPU Mhz increased.. So the game (Ragnarok Origin) really doesn't need the extra GPU power.

It goes up to 670 Mhz in CODM if I set it to beast mode...
