I'm not an expert, but I see that mining - to be profitable - need a lot of hardware and big investments.
I'm very skeptic that you can have results with just a cellphone.
Older cellphones can have 20-30H/s (about $5/month, maybe more once market prices get back) mining Cryptonight coins and they spend 5-10w of energy. One could buy dozen of phones and make a "mobile" mining rig which can be profitable.
