In "the good old days" (2015), a cluster of 4 cheap smartphones would make $100/month mining Perk. --- End quote --- Yeap, I DOUBT that the people controlling this are actually using it for cancer research. IMO They're most likely using it for crypto mining or simply for SPAMMING people. Computer power is CHEAP any more. There is no valid reason for anyone that is doing any VALID research to be running it off of a cluster or cell phones or other people's computer except for purposes of fraud! |

What I’ll do next is see how much current is flowing into the phone at end of charge in the morning both with and without the app running and report back here. Then maybe someone with the relevant skillz can tell us how that compares with the energy usage of a supercomputer doing the same job. --- End quote --- Okay, I tried it on my tablet. A Samsung Galaxy Tab A (8.0" 2019). When fully charged and the app not running it takes a pulse of maybe 30mA every minute or so. Bit hard to tell with a digital meter that updated infrequently. With the app running it takes a steady 15mA, so at 5.25v that's about 79mW. Not a lot. So... the question is, how much work per watt (actually per Joule) is it performing compared to a supercomputer? |
