I guess you're right. My bluetooth experience is Macbook, iPhone, Apple keyboard, Apple mouse and Apple headphones. Everything works extremely well. The thing that I like most is power indicator integrated with iOS and macOS. Allows me to charge those things before they run out of power. As long as you stay in the garden, things are smooth.

That's just... the BLE battery level service? AFAICT Windows does the same thing when you connect a BLE device that reports a battery.

I have no idea, I've read reviews from some bluetooth mouse and reviewer mentioned that macOS does not display its battery level. I thought that it's proprietary.

It is kinda funny, it was this behavior among others that made me switch from android to an iphone. I got so tired of BT shenanigans.

I do feel sympathy for the people still having trouble, but mine has been flawless. I do not, however, drive a Lexus.

My cars are all older, but my Android pairs up with a Kia Sportage almost immediately after starting the car. My wife's iPhone 11 sometimes takes several minutes. She ended up getting an adapter to connect audio to the 3.5mm jack.
