    After updating to oreo the idle clock speed of cpu is higher than normal. Is this a software problem. the phone is not able to enter into the sleep mode. it's happening after Oreo update 5.0.3

    i mean , if the screen on the app opened and others you don't see , means that the phone is not idle

    same here , even the exact numbers

    before Oreo the idle speed was 300 MHz for all cores . Still I am not able to understand why the high performance cores ( cores 4-7) are clocked high as they uses more power. i am just saying is it due to the cpu patch they installed.

    well maybe android just changed the API for accessing the cpu speed and it's showing some estimated valves idk. I agree with you that battery bakup is better in Oreo.

    Well in the change logs there's a reference to a CPU patch that prevents certain exploits by restricting access to high precision timers. So if I had to venture an educated guess, I would say it's related to that patch.

    Since the beginning of February I'm running on Open Beta 5 (OnePlus 5). Is there already more information about what the exact patch is, how it affects cpu speed, performance and battery drain?

    I did ask them again a while ago, they said it could be something caf merged for the Jan patches against meltdown, spectre. They aren't sure but it is on their list.
