well it's more the fact that 2 year old s23 ultra battery last longer then my s25 ultra , it could be Todo with one UI being rushed out as I have noted lots of issues that are still there that I had on the beta before I upgraded which I have reported, and yes I know it's a fast processor but Samsung does came it's better battery life but it's not the case it could be because I used the smart switch app to copy everything over I usually download it from the cloud , I get a lot of battery drain over night even with battery saving mode on and app background apps disabled just to see if it made a difference but it's not I loss around 20/30% overnight , I do see high usage on one UI home but I have rest and cleared my system cache as well so I have no idea , I was told by Samsung that there is high amount of bugs still on one ui 7 but they will be sorted soon that was last week they said they should be an update coming this week coming so hopefully if that's true that should improve battery on the s25 ultra , also for.you to get that SOT are you connected to WiFi all the time? as that's around the same as what I can get on my s23 ultra when it's on WiFi most of the time , and no I'm still happy with my s25 ultra as I know it will improve with coming updates
