Hmm the article I read about it previously seems to be eluding me, I’m going to keep looking for it. From what I remember of the other article, the short of it is, in android, location services can turn on your bluetooth at any point and does every time it gets pinged by google without you turning it on, and they are rolling out a new feature to automatically turn it back on next version. Here’s an adjacent article that talks about one of the future android features, where you can have your phone found even when powered off, and that is using location services, which does involve bluetooth.

Turning off your bluetooth doesn’t mean it’s off until you turn it on Bluetooth is on at all times on modern androids/iOS, as of android 13 due to location services features.

Edit, inaccurate phrasing on my part

Makes the growth 30% easier when it’s 20% less!
