INVN was my former employer (~2013), so I'm quite familiar with the details of both of these chips. I'm not sure just how much I am allowed to talk about these parts, but imo the general consensus regarding power consumption being the killer feature that got Bosch the secondary accelerometer socket win seems correct to me. The likely accel only features are screen orientation, pedometer, and activity recognition, as the articles suggest. (I personally don't think that the 1ms vs 20ms start-up time matters much though)<p>Also, (a) ST microelectronics parts always had quality issues so I'm not surprised that they lost the socket to Bosch, and (b) I expect Bosch to be selling the BMA280 at cost or even at a loss. Bosch was a late entrant to the consumer electronics accel/gyro world, and has always been keen on price dumping to win sockets and market share.<p>edit: the more I think about this, the more I think that this is a situation where ST was the only loser. They had both the accel and gyro sockets before, but essentially lost the gyro socket to INVN and accel socket to Bosch. The integrated accel in the MPU-6700 is more of an add-on feature for low power on-chip sensor fusion that was not capable with the ST solution that was previously used (the DMP in the 6700 pre-dates the Apple M7 chip that was touted for low power activity tracking usage, but given that Apple has the M7, I'm not sure how much of its capabilities are being used. My guess would be that it is only the on-chip 6-axis SF that they are using). The ST socket was simply taken by Bosch.
