It’s no secret that the new iPhone 6s and iPhone 6s Plus equipped with batteries of smaller capacity than their predecessors. However, the battery life of smartphones remained at the same level. This should facilitate energy-efficient chip A9, built on 14-nanometer process technology, as well as a new feature in iOS 9 called Facedown Detection – definition of upside-down position to turn off the screen when the device is not used.
Unfortunately, this mode does not work on iPhone 4s and iPhone 5, all iPad models & iPod touch. But what he is so helpful and why only available on smartphones last three generations?
Facedown Detection – this is an underrated feature in the Arsenal of iOS 9, which can be very useful. Utilizing motion coprocessor and accelerometer, the iPhone automatically determines the position of mobile device is located. In that case, if the phone lies on the table face-down, incoming notifications will not be displayed on the display, which will save battery power. Such a solution will help users extend the battery life of devices.
The question of why not all smartphones with iOS 9 support this feature. The answer is simple: the motion coprocessor “M” appeared only in devices 2013 model year. iPhone 4s and 5, not having such, can not without the expenditure of energy to collect and process in the background data from the gyroscope and accelerometer.
The motion coprocessor in the iPhone, iPad and iPod touch:
- M7 – iPhone 5s, iPad Air and iPad mini 3
- M8, iPhone 6, iPhone 6 Plus, iPad Air 2 and iPad mini 4
- M9, iPhone 6s, iPhone 6s Plus, iPad mini 4 and iPad Pro
I must say that theoretically Facedown Detection can earn on all your Apple gadgets. The ambient light sensor and proximity can replace the notorious co-processor, determining, lay the device face down or not.
A reasonable question about unavailable functions can arise and the owners of the new iPad. All “Apple” tablets starting with the iPad mini 2 is equipped with a coprocessor to the line “M”, however, Facedown Detection is only available on the iPhone. The fact that “the pill,” unlike smartphones, are supplied without proximity sensors. The same is true for the iPod touch.
Maybe someone function definition inverted generation will not seem so necessary. You can turn this off, but a special switch for this to be found. You need to turn off the Tracking fitness in the section “Privacy –> “Movement and fitness”.
