iOS 10 tips: Revert Touch ID from 'press home to wake' back to rest to wake
Slide to unlock is gone in iOS 10, and isn't coming back. In its place is "press home to unlock" which works well for the iPhone 6s and newer, but isn't so smooth for older phones, requiring two button presses to open a phone. Here's how to only have to hit the home button once to unlock your older phone with Touch ID.

Phones with the M1 motion processor have "raise to wake" enabled by default in iOS 10, which senses when the user picks up the phone and wakes the phone. Older phones with Touch ID don't have that ability, requiring users to press either the power or home button, and then press the home button with a registered digit again to unlock the phone.
Here's how to turn "press home to unlock" off, and change Touch ID's iPhone unlock feature back to how it worked pre-iOS 10.
The text on the home screen doesn't change in iOS 10.0.2 after the procedure is completed, it says "press home to unlock" regardless of setting. However, after toggling the setting, a registered finger rest will in fact unlock the phone, regardless of the lock screen's directions for the user.
This tip is also useful to revert the Touch ID button back to its previous behavior under iOS 9 even with M1 iPhones.

Very surprised that the need to press the home button is the default.
(The JB is utterly gorgeous, btw).
Though getting into them by Force Touch is hugely annoying and doesn't seem at all thought through as an interaction. So awkward.
I certainly think the defaults are back to front, but I don't see where you're coming from with your complaint.
There are enough threads about the headphone jack, let's just talk about the home button.
If TouchID is to be the normal mainstream way to open an iPhone, they had to make this change.
And if anyone is feeling overly generous, can you please tell me how I can stop all the travel time reminders I keep getting for every calendar event now? I never got any before the iOS upgrade. And yes, all my calendar events have "Travel Time" set to None.
When I (short) press the home button with screen locked and keep my finger on the button my iPhone unlocks just nicely and goes to my home screen right away..
And even before, I woke up my iPhone without unlocking it by pressing the power button instead of the home button, so I never had the unwanted unlock problem in the first place, and still don't have it..
So, with iOS10 I had to change exactly none of my habits, at all.
Unlike before I can now also unlock my iPhone without going to the home screen, so I have a feature more, but then again, doesn't differ that much from just clicking the power button..
So, all the fuzz about the changed behavior of the home button totally passes me by..
Better yet, set your alarm at the time when you have to actually get out of bed, so that you have longer uninterrupted sleep..
1. Slide to unlock requires 2 step to unlock the phone. With Touch ID, who needs to slide? Just press the finger on Home button to wake and unlock at the same time.
2. Home button has been used since the first iPhone. No one complainsed of its longevity.
3. 3.5mm port needs to go sooner or later...no big deal!
