iPhone 6s saves power by turning off ‘Hey, Siri’ when the phone is in your pocket or screen down

The untethered представлена ​​Hello, Siri ’was introduced in the iPhone 6s. Through this function, voice assistant

can listen to you constantly even when the device is not connected to power, the co-processor M9 of the new iPhone chip is used for this.

However, as AppleInsider found out, your phoneautomatically disables this feature when it is in your pocket or lies face down on the table. Thus, Apple decided to save device energy.

Engaging the M9 co-processor included“Systems on a chip” of the A9 processor in the iPhone 6s and 6s Plus smartphones, these devices can detect when the ‘Hi, Siri’ unattached function should be active, and temporarily disable it when the smartphone is “face down” or in your pocket. Initially, this technology was intended to automatically turn off the display backlight in similar conditions.

Usually it is displays that absorb the mostthe amount of energy the iPhone’s battery, and to save that energy, it would be wise to determine when no one is looking at the screen and turn it off, AppleInsider says.

Interestingly, this functional detail was not covered in any way in the advertising campaign of new devices from Apple.

On previous-generation iOS devices ‘Hello,Siri ’was only active when the device was connected to the power source via a cable, since the economical co-processors on these devices were still unable to recognize the voice.

Neil Hughes, the author of the material on AppleInsider, jokingly said about this: “those who want Siri to listen to them all the time should have the habit of always holding the phone face up.”

With the same facedown detection, your phone does not wake up when it receives a new alert, being screen down.

It should also be noted that facedown detection is not supported on iPhone 4s, iPhone 5, iPad and iPod Touch, as these devices lack a dedicated co-processor.

Apple M-Series chips require very little to workenergy and are used as so-called co-processors for continuous monitoring and calibration of numerous iPhone sensors, including the sensor used for face detection. Thus, the CPU relieves the load caused by these processes.
