look, everyone parrots that wireguard is a battery-saver on mobile because it's less code. ran a dumb test: identical usage pattern on two phones, one wireguard, one openvpn, for a week. monitored battery health and drain per hour. the numbers are basically a rounding error. maybe 3-4% difference max. feels like people are just repeating a talking point without checking. like, yeah, it's efficient code but your display brightness and signal strength are doing 95% of the work draining your battery. citation needed on these wild claims.
