it must be calculating it by a ratio because i really do spend almost none of my life looking at that screen

quite looking forward to separating the phone/sms functions from the bank/nostr functions when my bv4800 arrives next week ... phone is gonna be rooted, almost everything except nostr and my bank is going to be removed, and it's never gonna see a wireless connection, it's going to be a point of pride to never let it connect to another device over radio 

 Nice device bv4800. 

I use different profiles on GrapheneOS to separate things Nostr and personal. It really should be another device, somewhat the way you do.

Intrusive things like nagging to uninstall or deactivate particular app by a bank app are concerning. Same with gotchas like 'screen time'.
