So many users are advised by tech sites to disable specific features in iOS to "increase battery life" or stop Apple from "spying" on you. What they don't realize is the hidden impact disabling features has in other parts of the system. examples: - Disabling "setting time zone" in location services > system services removes the "sunset to sunrise" option for nightshift and I also believe it screws up the sunset/sunrise time on the Apple watch. - Disabling background app refresh removes the new Google Maps widgets. - Disabling frequent locations prevents the Apple maps destinations from working properly. TL;DR Stop disabling iOS features you never know what other features/apps depend on them.
