CPU Boosts to the Highest Frequency When Switching Apps in RR-OS - Xiaomi Mi MIX Questions & Answers

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!

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..

Why is this killing my battery?? And will scaling CPU down work?? Post root Q's

I recently rooted and while I have not noticed the battery dieing faster the spare parts app is showing media and google apps in network as using up a lot of battery? Does anyone know exactly what it could be? I didnt use the camera, and i have noo music on the phone so definitely no media player. Ive maybe d/l two things from market (they were frozen for quite some time thought) and ive had google talk signed out since i dont use it and to save battery. I do have my gmail on autosync but again this was never this bad w/o root. The only apps i have now that I didnt have before root is autostarts (with somethings disabled) and wifi tether. Some screens below. I am on Cyanogens 3.6.8.1 rom with the newest spl and radio. As of today Im on apps2sd and linux swap but the media folder was definitely like that before partitioning.

Also wanted to know if on this Cyanogen rom if installing one of the overclock apps and scaling the cpu down during sleep actually work on this rom? i tried the overclock widget and set it to 528 528 when screen on and as low as it goes off but i just wanted to know if this is actually working because when i turn the screen on the widget is at 528 (updates every 5 secs) and i dont know if its actually going up to 528 that fast or if its just not underclocking???? Thanks for any help guys
i wouldn't recommend setting your idle speed much lower than your screen on speed because more battery will be used having to go from the lowest speed to 528. the scaled cpu in cyanogen's rom works great for me. i have long quit using any overclocking apps
what rom is it

You are not the only person. I have the same exact symtoms, by doing the same thing, with the same widget, on the same ROM.
Good luck, once I unrooted and got the OTA update to CRC1 my battery life is better, but no where close to what it should be. Also I could not hit 100% charged until I unrooted. Now I can whenever the phone feels like it.

overclocking our Diamonds (MSM72XXX) to 768 MHz!!!!!!!!

"Touch Pro running at 800MHZ???
By No2chem6. setembro 2009 22:58
I swear it’s working, really, see screen shot attached… Short story – I knew that the number of clocks on MSM devices are limited (Actually, that’s a pretty relative term – the MSM has a LOT of clocks for a single chip), the main problem is that there isn’t that much resolution with the clocks, and that there aren’t that many high clocks to choose from – in fact if you look at the clocks available on MSM devices, we have:
TCXO: 19.2 MHz (for CDMA clock)
GlobalPLL: 800MHz
BackPLL0: ? MHz
BackPLL1: 1.056GHz
PLLTest: ? MHz
USB: 48MHz
Sleep: ? MHz
So the standard frequencies for the MSM are obtained by BackPLL1 / 2= 528MHz or GlobalPLL / 2 = 400 (384) MHz.
But just a few minutes ago, a lightbulb lit up in my head, why not just TRY setting GlobalPLL / 1 for the applications ARM? … And to my surprise, the device didn’t freeze.. it worked just fine actually. And there is a noticeable improvement in speed ( ~ 330 integer @ 528 MHz , ~456 integer @ 768 MHz).

I guess this’ll be finalized into a tool for some sort. Guess overclocking this thing was possible =p.
Note: Before I get a bunch of stuff about 1.056 GHz, no, it didn’t work on my Touch Pro, it locked up!"

[NEW/APP] Root Booster - Boost your performance, battery life with innovative tools

Root booster is for those who needs more power to run applications smoothly without lags or for those who needs to improve poor battery life.

There are many apps which save battery or incrase performance, however Root Booster uses the most proven settings to achive best results. You can easily apply these settings with preset modes which ensures speed boost, battery boost or stability boost. Theese modes are achived by applying appropriate settings to main phone components. Here are explanations what particullary Root Booster does to your CPU, RAM and Android OS system.
CPU (processor governor control)
A governor is a driver for the regulation of CPU frequency. Governor decides how fast and when will by achieved maximal or minimal CPU frequency. Setting apropriate governor makes your device more battery saving, fast or even stable. However deciding which governor is suitable is a little bit tricky. Root Booster can decide which governor you should use and automatically apply the most suitable governor for selected mode.
RAM (memory manager)
Each application uses VM heap for it 's data and work. The main reason to change VM heap size is stability improvement. Many big applications need's big amount of memory (VM heap) for it's work. If the VM heap size is smaller than requested memory causes application crash (Out of memory error). Setting heap size is hard task and there is no manual to set up for better performance. Better performance can be only achieved by testing. Root boster will test your RAM and sets up your VM heap size for better stability and performance.
System (Android OS optimizer)
Each Android application can have one or multiple services. They are running in background and usually performing some kind of task. Many people think's that when they kill application it completely stops draining your battery and computing power, but that's not true. Application still have servicies that are running after killing and still drains battery and comuting power. Root booster will scan your services and disables the most battery draining and performance demanding servicies to optimize your system.

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...
