I'm curious if the existing cpu performance of even mid-range modern phone SoCs is really even used by most users. I suspect gamering and winning benchmarks may be the primary use cases.
I was trying to reduce power consumption on my phone, and disabled all but one low perf core (the phone's SoC has 2 high perf and 4 low perf cores), and things were very noticeably laggy.
But, then, I tried with only two low perf cores enabled. Everything that I used my phone for (calls, messaging, notes, web browsing with an ad blocker) worked fine. So, the extra four disabled cores really didn't affect my ?average? use case.
I was concerned about consumption during active usage, not idle, but disabling the cores didn't affect power consumption for either (even with only one enabled).
