One of the simplest new features in iOS 10 is the feature "Lift to activate" ("Raise to wake"). However, what is simple is also efficient: just take the phone out of your pocket or on the table so that the screen quickly lights up, making it easier to view notifications.
After the release of the iPhone 6s, which came with the second generation of Touch ID, this feature will fit like a glove! This is because the sensor was so quick to recognize the fingerprint that even if you touch the button just to view the notifications, the device is instantly unlocked and you are taken to the home screen.
the kind of thing we think: why didn't Apple implement this before? The answer, while it may disappoint many users, apparently may have to do with the iPhones' coprocessor.
It was on the iPhone 6s that Apple implemented the ?E Siri? feature the way it should always be: you speak the phrase and the assistant responds, regardless of whether the phone is connected to a power source (wall charger or vehicle, computer, etc.). This, according to Apple, was possible thanks to coprocessor optimization and efficiency M9, which can monitor the device's various sensors without wasting a lot of energy.
The same thing goes for the new ?Lift to activate? feature, which also makes heavy use of sensor monitoring to know the exact moment when the screen must be activated so that the user can view the notifications without pressing the Start button (Home). Because of this, the feature will only be available for iPhones 6s / 6s Plus and SE (those equipped with the A9 processor and M9 coprocessor). As far as we can imagine, if Apple implemented this in older iPhones (6/6 Plus and its predecessors), the feature would consume a lot of energy, directly impacting the useful life of the battery that no longer does these things.
Obviously, the iPhone 7 (or whatever the name of the next iPhone is) and its new (co) processor also support the feature.
