I think it's difficult for make that happen. Because if you mine with smartphone how to cooled it? if the computer has a fan and water cooling. As far i know computer have better performance then laptop. And computer must have some componets to mining. If used smartphone, How much smartphone you will needed?
It`s not difficult, it`s impossible to mine bitcoins with phones. You can`t mine bitcoins with computers too, you need miners, serious miners with huge hash power to be able to make some profit. Mining with computer cpu will just make your computer to explode. All you can do with computers and smartphones is to register on some cloud mining site, or some faucet miner, which is not highly recommended, I just say what you can do. Today, in order to be profitable with Bitcoin mining you need to invest heavily in equipment, cooling and storage. Its not possible to mine profitably with a PC or a GPU at home. You can calculate your profitability using a Bitcoin mining calculator, you can find it easily with simple search. If you don`t have power and you wish to mine you need to find some coin with low difficulty and mine that coin, they are mostly very cheap but so was bitcoin in the beginning, maybe they can worth a lot one day in the future.
