This did bother me when I was still an OpenVPN server to connect my iPhone while away from my home WiFi. It really did measurably affect battery life. I’ve switched to wireguard since, using on-demand activation so it enables the VPN whenever I leave my home WiFi, and I can only say it has almost no impact on battery life whatsoever. According to the iOS battery stats wireguard accounts for about 3% of total battery usage on working days (vpn active most of the day), which is worth it as far as I’m concerned.
