My phone takes less than 40 seconds to compute 10 million decimals of pi. I still remember when computing a few million decimals of pi would take hours of mainframe time.

Take the performance of a Surface Pro 4 (i5-6300U) which is on par with Galaxy S7 (the real version - Exynos) and it can do 10M in half the time that this takes with Mathematica, on a single core. And Mathematica isn't even optimised for Pi. Learn some high level mathematics, and maybe some assembly while you are at it. ARM should have a performance edge over X86 because the instructions allow putting the result into a different register.
