Has anyone tested battery impact of VoLTE?

I don't get much signal at home so always using WiFi calling, and as such haven't been able to test standby drain with VoLTE Vs without.

In theory VoLTE should improve battery life as the phone doesn't need to connect to 2g/3g to make calls, but seen a few potential issues.

Anyone tested it out in like for like conditions? I.e. leaving the phone overnight

Yeah VoLTE drained my battery alot (galaxy s21 ultra). I used to get 6-7 hours of screen on time but after VoLTE I get only about 4 hours, so I turned it off immediately.
