Wait.. let's figure here.. 2c/hr = 48c/day
Electricity cost might be 25 c/kWh, and let's say that wall wart draws 5W, so 0.120 kWh/dy, or 3c/dy - that works out ok.
$0.45/day = $13.50/month.

Now, the real cost - how much is your time worth? $50/hr is very cheap for someone on this list.  If it takes more than 15 min/month to deal with it, it's going to be a money loser.

    Agreed, I wouldn't accept 2c/h for something that runs at full power and
    drains the battery. But if the thing runs only when the phone is
    connected to a charger (& wifi if it needs to communicate), then it's
    slightly less nonsensical.
    Also, could be a use for old phones that otherwise would just gather
    dust in a drawer or be thrown in the trash. Of course, if they pay for
    compute performance (for some suitable definition of performance) rather
    than just cpu-hours old phones will be less power efficient.
