So you never put your phone in low power mode?

btw you sound like a nice guy!

Thanks for sharing the info, I’m using the free version on a 2015 MBP and intend to get the pro version when I get my new 16” MBP — given you have the new 16” model and a 15”, have you found the Utility as effective on the 16” with i9 , and any obvious differences between the free and pro version?

Absolutely yes. The 16" seems (that's arbitrary thought, not scientific fact) to crank up the turbo boost, and subsequently the fans, much more frequently than the 15" did.

Quite frankly, I run the 16" MBPro with macOS 10.15.2 with TurboBoost turned OFF nearly 100% of the time and notice no difference in performance, I also almost never hear the fans come on and the battery lasts longer.

I have the 15", the super hot i9 one. Running 100% with TB off. You can't notice the difference in speed.

There is some facts that can't be ignored how Turbo Boost works.

1. The CPU runs at stock frequency until is needed, and when this happens, Intel intelligence fires TB. This can take fractions of seconds, vital for some kind of low load.
2. The Turbo Boost is only available with 2 or maybe 3 cores are in use simultaneously. The other cores are kept running stock.
3. Once activated, the CPU's cores receives more voltage, that increase frequency and generate heat. When heat is close to 90º, the CPU cuts voltage to normal level, and the heat level drops. So it injects more voltage... It work like a roller coasters. Getting up and down in a matter of seconds.

The idea behind it should work for simple tasks, based mainly on the use of one or two cores simultaneously. In CPUs with 2 cores it works like a breeze. In 4 cores CPUs it works just ok. But with 6, 8 or 12 cores it doesn't make sense.

Because once active, Intel will concentrate the load in just two cores. While you level-up two cores the heat generated hits 90º almost instantly.

And with the TB off, the load are tackled by more cores, maybe all of them.

If we would care for single core activities, TB off maybe will affect performance.

But what are the tasks we use this days that are single core?
