Similar systems are also widespread for smartphones and contain numerous fraudulent complaints. For example, there is an iOS supported mining application named MobileMiner which is based on iPhone X. To use it, you have to be an iOS developer and not use the device during mining. It's impossible to use it because of the overloading of the processor.

In addition, applications that demand such hefty processing power in the background are bringing your phone to high temperatures. We need to note that existing mining systems have water-cooled motors and that even the simplest equipment adds 4 to the electricity bill. But you said that you can not work because of material costs and you want to mining with your iPhone X. You have taken the facts above and prepared everything. How much do you earn?
With the iPhone X, which only mined 8 hours a night for one month, this figure reaches 13 dollars hard. A whole month later, it's now a garbage iPhone X and 13 bucks ...

It does not make any sense.
