    In airplane mode and even while turned off, phones have been known to still transmit data via background services. Leaving it behind, or a Faraday bag are the only assured options I’m aware of

      Not while turned off, generally. Screen off, sure.

      Edit: apparently at least some do

        Thats not correct. Iphones and androids are never truly off. There are a few privacy focused phones by small makers with hardware switches for each radio. You can run android or linux on them.

        There is no such thing as “off” on modern Smartphones. Even if you power it down things like the baseband prozessor and bluetooth still stay active most of the time.

        If the battery is integrated into device there ist no real way to completely shut this things down.
