Unfortunately, there are other places that software launched at startup is embedded. It's almost as bad as Windows Registry.  

Apple's own launch agents and daemons are in :

/System//Library/LaunchAgents
/System/Library/LaunchDaemons

You'll also find 3rd party system wide startup items in 

/Library/LaunchAgents
/Library/LaunchDaemons

That DO NOT appear and cannot be controlled or listed as described in this note. I've had to purge items from those locations too many times—such as MalwareBytes Mac which continued to launch services and a menubar applet despite not having any active services running (I was out of the trial period on the free monitoring).  

And user specific ones are held in 

/Users/<username>/LaunchAgents

where <username> is the user's home directory. When trying to remove things that launch at startup or login, you'll need to look first as described in the article and then backwards through the lists here. And possibly also when removing software you no longer use. 

Unfortunately, its would appear, on the surface, that this slowdown feature was originally designed to cover up battery defects in the 6 series of phone. That said, it makes sense to add it to the functions because batteries age and performance drops—but you should be advising the user or allow them to choose higher performance at the cost of battery life just like everyone does in laptop power management and in fact, Android devices allow you to do. 

All that said, the situation reminds me of Honda's fix on their hybrid Civics that were experiencing shorter than desired battery life. Honda changed the ECU programming so that the gas engine ran more often to extend battery life. With the commensurate severe drop in gas mileage (by 10 MPG or more if I recollect correctly). Honda's action resulted in class action suits which they lost with some fees and at least one class opt-out suit in small claims court where Honda I believe was forced forced to buy back the car or at least provide a much more substantial award than the class action. <https://www.greencarreports.com/news/1072475_woman-wins-suit-against-honda-for-low-civic-hybrid-gas-mileage>;

Don’t know why Apple didn’t use 3D Touch touch to either invoke options or simply open the appropriate settings app. 

Have problem not with the crown but with the side button sticking. A quick wash seems to fix that problem too.
