Franco Kernel Manager works for ALL devices and kernels.
You need to be ROOTED for all features besides Battery Monitor which works rootless.

Franco Kernel Manager makes use of the AccessibilityService allowing us to detect the activity displayed in the window. As as example, when this service is enabled and running whenever you open an app we are alerted through the api the visible window state is changed, and we can infer the activity's package name and thus checking if we have a profile for said package and apply it. No data is collected/stored/logged through this process.

Ratings and reviews

this app is great with a lot of options. but it won't apply my settings through profiles that i set. example: i set two profiles, "power saving" and "performance", when i tap the profile, it says "successfully applied" but all settings are still the same how i left them.. i don't know if i made a mistake or maybe i just don't understand how to properly save settings for each profiles. Reply Update: Yes, governor profile.

So, I bought this a while ago but I didn't post a review... ...I don't know why not. It's great value and brings a new lease of life to all the devices I've installed it on. For example, my OnePlus One running LineageOS has great battery life again - on its original battery! The list goes on. My only regret is that my company phone, an S9, can't be rooted (not allowed to) and isn't explicitly supported - its battery life is questionable. Maybe I can get them to buy me a phone from the list. If you are wavering and wonder whether you should buy, just go ahead, you won't regret it...

The app is very good and it has really affected my phone's performance and battery life. But one issue, whenever I turn on Underclock CPU , and try to turn off it doesn't turn off. I have to reboot my device. Is there any fix ? Edit : Actually, when my battery becomes low, I underclock the cpu, and when it dies and after fully charging I tried to restore it, but it doesn't restore. that's the problem. But it was gone after I reinstalled the app freshly. It's very good to hear from you.
