Music will immediately cease playing when the headphones are taken off thanks to a proximity detector
and every charge will last up to 18 hours.
The proximity detector
in the chip is topped with an 830-nm to 880-nm IR filter.
The phone, which also offers speakerphone, has a built-in infrared proximity detector
that switches the phone off handsfree as the phone is brought close to the user's ear.
Some users have noticed that the cases, which no longer fit properly, now interfere with the iPhone's proximity detector
, which tells the phone when it is close to your face (and turns off the touch screen in the process).
Presented as extending the battery lifetime and reducing circuit complexity and component count in advanced portable devices, the proximity detector
in the chip is topped with an 830 nm to 880 nm IR filter.
