I have read that a scanner of another brand shows significant difference in performance when the connected laptop is powered by battery and AC power. It makes me wonder if my POP3 will perform differently when used with PC and mobile phone. Talking about an i7 , 16 GB RAM PC and iphone 11 pro.
Of course laptop or PC will perform better , it has much more power than any phone .
Also when using laptop for processing , make sure your power setting is set in Performance on your laptop/PC .
Scanning itself ( raw project file ) not matter much , as both performing well regardless as long your phone don’t run too many apps in the background .
Your PC will much much faster for both scanning and processing vs mobile phone .
