increase auto-lock time
Finally figured out how to increase it past 5 minutes...other thread closed but here is the answer.
Autolock is a bit of a misnomer. It's really a screen saver.
There's another place where we can change the time on the passcode itself. The default is 'immediately' which they never seem to tell you. So setting the passcode timer to 'immediately' is what turns the autolock screensaver into an actual autolock.
So now, when at home, I have my 'autolock' (screensaver) set back to 1 minute to save batter BUT I have my passcode set to 4 hours. Now when my screen goes dark just touching it wakes it up but does NOT request my passcode.
Go to
Settings
Then scroll way down (6th one after General which is in the 3rd section) to TouchID & Passcode.
Will have to enter your passcode to make these changes.
Then go to 4th section of choices to Require Passcode and then to the right in light gray you will see the word 'After'
NOW you can control the intervals for the passcode request SEPARATE from the Autolock time. It will most probably have 'immediately' checked off since, as stated above, it's the default. But that is what makes the autolock more than just a screen saver.
Now if finger print is used, this is all sort of moot.
But for those using a passcode it resolves the issue of having to type in the passcode all the time.
