You can mine ETN through your phone. This is how its works.
ETN calculated how much hashrate you have if your phone is in perfect conditions.
I do it now for a couple of days and have 5 ETN with doing nothing. Battery is still normal. (1 day intensive use)
What I've read with other ETN miners, you are getting almost the same number of ETN daily. This means that its really not about the spec of your smartphone but its designated to be used by its supporters and reward them with few ETN to make them look like they are mining which basically they really don't.
That's not mining - it's simulated mining and you could even call it some kind of airdrop.
Real mining on a mobile would just decrease the lifetime of your hardware without any profit.
Agree.
