I spoke too soon about battery life improving on Android 10, after initial small gains it now seems worse than ever, even on WiFi.
Same here. S10 battery drops like a stone on WiFi. I'm sure overall battery life has taken a hit on 10 (Q). I've also got an issue with blue tooth since the update. Audio cuts randomly when listening to audible and Spotify through by ear buds. Has done it when connected to vehicles head unit via bt. Have to disconnect and reconnect bluetooth to get audio back. I was getting some stuttering and apps being slow loading but this seems to have settled down. I have reset phone and cleared cache BTW. I think I preferred Pie
