I don't get how the hell the company that is laser-focused on power efficiency - like to the point of having separate display scanout RAM just so they can ramp down system DRAM separately - also has a perpetual problem with out-of-control daemons eating the CPU. iOS and it's derivatives should have the same problems macOS has, but we can't see any of the performance data on an iPhone (unless you're jailbroken), so this probably just crops up as random complaints about hot iPhones with flat batteries.
