Unfortunately this is not possible without sacrificing quite some battery power
Unfortunately this is not possible without using significant battery power
and adding a lot of complex code to do network translation from OSI layer 3 to layer 4
(and thus implementing a TCP/IP stack), which will inevitably introduce bugs as well.
This is how most (all?) other no root firewall work. NetGuard is unique,
because it doesn't implement a TCP/IP stack and is therefore both highly efficient and simple.
