Tested On Xiaomi.EU 20.3.5 BETA ROM, results may vary but worth trying.
What you'll need:
- Unlocked Bootloader
- TWRP
- Magisk
- SmartPack (on PlayStore)
I assume you already have an unlocked bootloader, TWRP and Magisk installed. If not, follow other tutorials on this forum, there are plenty of them
1. Go to Magisk, Downloads, and search for "Universal GMS Doze", download and install the module, Reboot.
2. Now download "SmartPack" from Google Play Store. Open the app and grant root permission.
3. When in the app, go to CPU. Now the tricky part starts. We really cannot change the frequencies, turn off cores and so on. If you click to choose a frequency , you only get 0mhz showing, and that isn't helping that much.
But somehow, I got it to work. I tried to change the CPU Governor to other modes, got into the GPU tab and clicked on GPU Freqencies, and then force closed the app. Opened the app again, go to CPU, click frequency and happy days! You are able to change your CPU frequencies for your big and small cores! Now, it isn't flawless because you cannot control individual cores, but you can control big and small cores together, and that's enough to get this working.
Now you can go to the big cores, and small cores, and set the lowest frequency to 300mhz and the highest frequency to 300mhz. You may think this will slow down the phone totally, but the CPU will boost past that if it needs power. If you feel the phone is unresponsive, you may change frequency on the bigger cores, or on the smaller, or both to a higher frequency. You may test different settings to achieve your sweet spot.
Remember to tap "Apply on boot". And that's it! It worked for me! If any questions, let me know! I'll try to answer them. I hope this method works for you! :fingers-crossed:

Its available in playstore. It should work with any kernel. I bought It for my old RN4, but im gonna try with my new note 10. Battery is pathetic for me. 1 single day and 7:30-8 SOT Max. Huge standby drain too... Im in latest Xiaomi.eu weekly

Hi there guys!
My battery usage is very poor with a new xiaomi mi note 10. It drains battery fast even in standby. So how do I install this franco kernel? In play store I can see "Franco Kernel Manager" for 4 USD (43SEK). Is it this one I need? What settings after that? Is there some guide to this?

You need ROOT for Franko Manager
--------------------------------------------------------------------------------------------------------------
I'm installed
Magisk v20.4 for Root
Franco Kernel Manager (Play Store)
And I set my CPU like on screenshot, min 300Mhz and governor "conservative" I can even switch off core in CPU
Will see how standby time will be look this time

I think "conservative" governor is better than "ondemand" for battery... will test this

Thanks.
Conservative is better,i think

So to be clear, I need to pay for the franco kernel, then after that I can just apply the settings in thoose two images provided by @veimus?
This setting should be on always? (Even when playing some stupid game or something?)
I already have bootloader unlocked, rooted and magisk installed.
