    power modes for free-fall detection in BMA253

    Hello,

    What is the most power efficient modes for detecting free-fall?

    I actually ensured that I can detect free-fall in Normal Mode.

    Total Supply Current in Normal Mode is 130uA.

    So if I use CR2016 lithium battery (which is 90mAH), the battery life will be 90mAH / 130uA / 24 hours = 28.8 days.

    I want to ask if there is more power efficient ways in detecting free-fall.

    Thank you.

    Hello Coleman,

    To detect free-fall and save power consumption, you could use lower mode 2.
