To be fair, my nova is currently at 0.9% battery usage.
Something to remember is that the built in UI should always show less power draw because the rest of the system is integrated around it, so some of the battery use for it will also be android system. As well as widgets power draw will show up for any third party launcher.
I'm not doubting you by any means as different people have different use cases and will experience different power consumption based on that, I'm just going off knowing that Samsung's launchers have always been known in the past to be fairly bulky.
That and I love nova prime. I think it was the first app I actually ever bought lol
I can't comment on the newer Samsung launchers. I guess just keep an eye on Nova.
It's the only one I would try as a boot loop may be your reward for trying others... as I learned.
I have 2 10+'s now because of Samsung's and Android's recent blunders.
They will be my workhorses for the next 2-4 years. The latest new 10+ is running on Android 10 which doesn't seem to utilize scoped storage on any of my apps unlike 11 would. It runs well.
I haven't run it that long so I'm just learning it's power usage profile. It seems similar to my Pie variant at 7-12%@hr SOT.
The Samsung launcher on my S4+ was slow and a power hog. The newer launcher on the 10+ is snappy fast, efficient and rock solid stable. A exponential improvement, to be fair Samsung did an excellent job. Hopefully they didn't regress.
You are however missing out on all the Samsung customization.
Other brands need all the help they can get, not Samsung. Samsung's are the most customizable stock Androids on the planet once you learn to work within their framework.
Pick a theme (the default high contrast themes work well) which also controls the phone, keyboard, messenger etc appearance then pick a icon pack, then pick a wallpaper for the screens.
Add the Good Lock family of apps and One Handed Operation plus.
Add other 3rd party apps like Digi Clock widget and Double Tap.
Once you learn how to do it and what you like, setup doesn't take long. SmartSwitch can restore most of the settings... maybe
