Personally I am very slow at typing on my phone. Always have been, I’m old at heart. I also find inputting values with large exponents to be inconvenient and slow. So if I’m not by my laptop, I tend to do quick calculations in my head, then only use my phone to double check order of magnitude. I actually prefer pencil and paper to typing on my phone a lot of the time.
Edit to add: My wife prefers to use her calculator, and is usually a tad slower than me, but does catch errors I miss, maybe one time in 10?
