The new iPhone 6 and iPhone 6 Plus are equipped with two accelerometers
Apple has chosen to equip the iPhone 6 and 6 Plus with two separate accelerometers, as was found in the Chipworks desmotntar both devices. There is a three-axis accelerometer and Bosch BMA280 from Chipworks is believed the other accelerometer MPU-6700 is InvenSense six axes.
According to Chipworks, Apple may have decided to incorporate two accelerometers in the iPhone 6 and 6 Plus both minimize energy consumption, to "improve the overall user experience."
The InvenSense accelerometer has a number of functions, allowing it to operate in several different modes, but can have more power than the Bosch accelerometer due to its higher sensitivity. The maximum sensitivity is 16,684 InvenSense LSB / g, much higher than the Bosch 4096.
The InvenSense device can operate as a six axis inertial sensor, either as a three-axis gyro or a three-axis accelerometer. It is designed to consume 3.4 mA in the six-axis mode, 3.2 mA in the gyro mode and the normal 450 uA accelerometer mode. Rather, the device operates as only Bosch 3-axis accelerometer and 130 uA current consumed in the normal mode accelerometer. Both devices offer two levels of low power operation for the function of accelerometer. The InvenSense device actually uses less power in the lowest power mode, with an update rate of 1 Hz.
The main benefit of InvenSense is the full integration of the six axes of the data by the digital processor of motion in the (DMP) chip. This will provide a direct benefit for games and other applications that require sophisticated inertial sensing capabilities. Furthermore the InvenSense provides significantly greater sensitivity than the Bosch device. The price however, is a higher energy consumption.
The Bosch accelerometer is capable of operating at a lower than the InvenSense power and has a "much faster" cold start, in comparison, 3 ms compared to 30 ms, allowing it to be used when complete integrating six axes. As noted from MacRumors , Chipworks speculates that can be used for tasks where greater sensitivity is required, perhaps by rotating the screen from landscape to portrait mode or pedometer functionality.
We'll have to wait a little longer to see how far it is able to help the arrival of two accelerometers to the new iPhone 6 and iPhone 6 Plus and if you are able to save as much energy as the guys at Chipworks report. What do you think Apple has included this new feature in their new smartphones? Do you think it is something that really help the performance of the devices?
