I'm not that satisfied from my Galaxy S20 Ultra battery, honestly. I tend to lose 7-8% of charge overnight, with the phone having only Wi-Fi active and no notification-heavy app at all (I didn't even make the switch to my instant messaging app yet, which is still on my previous phone).
While looking online I read on this site and elsewhere that some people have tried to factory reset their phones without using Smart Switch during the first boot and the issue was solved. I personally used it and heavily, by picking each and every option the app let me select from my previous phone, hence why I might be an extreme case.
Is there any truth to something like this? It's not like I don't trust other users' valuable experiences, but it seems a little bit farfetched. If some of you could confirm it then I might convince myself of factory resetting and start over again.
What does it have to do with anything I said?
There's no such a thing as a linked account to any cloud or online content in my new phone, as I've already said in the first post. No backup or update has been made overnight, I checked it. It simply discharged a lot.
What about the Smart Switch influence? Could it be, according to you?
I did it, and nothing came out of it. It shows display and system UI as the main culprit for the battery draining.
As for Google, yes I signed into my account but I made sure that it isn't performing any backup. I'm accustomed to it.
You won't find Smart Switch in the battery usage according to people I've talked with, the problem is not Smart Switch per se but issues with the transfers (especially of apps) that drain the battery. People really experienced severe differences when doing a factory reset and not run Smart Switch at first boot.
Now I'd like to know if this has some inherent truth or it is just some rumor.
