    It sounds like your Mayfly is not actually going to sleep.  An idle Mayfly will use around 6.5mA, and a sleeping Mayfly will use between 0.25mA and 0.5mA, depending on whether you’ve got a microSD card in the slot and the type of card.  Here’s the power consumption results from Mayfly current tests:

    Mayfly current when board is powered and idle: 6.5 mA
    Mayfly current when MCU put to sleep and no microSD card in socket: 0.27 mA (or 270 uA)
    Mayfly current when asleep with microSD card in the socket: 0.43 mA (or 430 uA)
