Apple’s iPhone 6 and iPhone 6 Plus are reportedly loaded with two accelerometers which makes them the most sensor-laden devices Apple has ever released. After an extensive teardown, Chipworks reports that the new smartphones from Apple are using two different accelerometers.
First of the 2 accelerometers is Bosch’s three-axis BMA280 accelerometer, and the other is reportedly InvenSense’s six-axis MPU-6700. As far as the reason behind using two accelerometers go, Chipworks believes that the usage of two components not only helps in better power management, also improves overall user experience.
The InvenSense component is more sensitive, can do more things than the Bosch component and it also takes more power. For gaming and other applications requiring “sophisticated inertial sensing capabilities,” these latest iPhones will be using InvenSense. But for more simpler tasks, such as rotating screen or tracking footsteps, Bosch accelerometer will be used, which takes lesser power and responds faster.
The Bosch accelerometer has a significantly faster cold start time of 3ms, as compared to InvenSense’s 30ms, which means user will see less delay. This remarkable use of engineering trick results not only in less power consumption, but also a better user experience.
Apple unveiled larger iPhone 6 and iPhone 6 Plus models during a media event on September 9th. Both smartphones went on sale on September 19th. The new iPhones have larger displays, bigger batteries, thinner body and runs iOS 8. iPhone 6 and iPhone 6 Plus broke all the previous sales record by with 10 million units sold in first week of launch.
