I’ve got two fixes that have helped me. The first is that I now have a bright folio case making it easier to spot. Black cases in the evening made it impossible. The second was Google home’s “find my phone”. From any room in my house, I tell it to find my phone and it’ll call. Huge lifesaver.
Worked great for a week, then the following week I had nothing organized and couldn’t remember where the bottle was left.
