The iPhone 6 and iPhone 6 Plus uses two accelerometers to save battery
An excellent example of the elegance with which Apple is coming to the creation of iPhone, is a new discovery Chipworks. The company’s experts have found that the new generation of smartphones – iPhone 6 and iPhone 6 Plus – just two integrated accelerometer. This technique Apple used to conserve battery power and capacity devices.
According to Chipworks, «filling» iPhone smartphone line 6 contains two modules that respond to changes in the orientation in space – Bosch BMA280 triaxial and six-axle InvenSense MPU-6700. Each of them can run in power saving mode. In previous versions iPhone used only one triaxial accelerometer.
Such a solution would allow Apple to not only reduce energy consumption, but also to expand the options of user interaction with the mobile device. Accelerometer Bosch is a standard component of the smartphone with a fairly low sensitivity and weak energy consumption. Module InvenSense, in turn, is able to accurately measure the position of the iPhone, but in this case it is more energy-intensive.
Thus, in standard applications iPhone 6 and iPhone 6 Plus uses standard sensor Bosch, whereas in complex games and applications enabled six-axle accelerometer InvenSense.
