for mining i dont really think so unless you happen to have a large number of spare devices that you can use which are constantly plugged in. mining is pretty much always going to be a very resource intensive process so its going to eat your battery in most cases.

There may be another system which could be possible but i havent looked into other solutions much, i know there is Xtrabytes proof of signature system which may be a good fit for mobile
