Dude, seriously, if you try such a thing, be ready to get a new phone. Mining bitcoin with a smartphone will first of all impact your battery life by draining and consuming your phone's energy, leading to your device getting spoilt.

No doubt, modern smartphones are more powerful than the first computer that was invented in the 1940s. But still, when it comes to Bitcoin mining, there are far more advanced and specialized computers for the job.

I'm sure you brought up this topic because phones are smaller computers, yes. But they have a limit to what they can handle.
