Many of the controls I'm describing exist as "widgets" on the iPhone — swipe left from the lock screen to see them.
But, in my opinion, swiping is one too many steps. If I'm navigating my phone, this information is no longer "at a glance." I want to be able to see this kind of information immediately once I raise or wake my phone.
Here's hoping Apple decides to upgrade the iPhone's lock screen in iOS 13.
