>>2834128>Assume phone is in airplane mode/battery removed with no bluetooth and the bluetooth on the watch is turned off aswell.Let me dumb that down for you:
>assume airplane mode does what it says it does, that is, cut all radio emissions>assume turning off bluetooth actually turns if offIf those are true, then no, you can't be tracked through electronical means. But if you trust your electronics, why worry about tracking in the first place? Big brother's your friend, right?
btw, my phone (Oppo 55s, bought while I was living in Japan) shows up on my linux-based computer's WLAN as a hotspot in range even when it's supposedly in airplane mode, with the Wifi hotspot turned off (never used it, actually), and supposedly not sending anything whatsoever. You'd think this was some weird bug - except that on windows and apple devices, it doesn't show. Considering that japs have a bunch of "safety" features on their phone (can't turn of the shutter sound of the camera, can't uninstall the government emergency notification app etc), I wouldn't be surprised if this was some feature to detect phones.
