OK, I am forming a possible theory as well. I pair them right now to my iPhone 13 Pro Max. I also have a Redmi Note 11 5G by Xiaomi, but Beats don’t carry a fraction of the music range and quality on Android they do on iOS 16.4.1(a). When I am not listening I unpair them to the iPhone, but I frequently see that if I check the Control Center, the icon for the volume will be a pair of headphones rather than the speaker, which informs me that the headphones have reconnected to the iPhone. AS LONG as the headphones are connected, they will drain their battery at the typical pace, since they have to power back up to reconnect. I am usually using Apple Music, but could also have been using Amazon Prime, or HBO Max, since you asked. I will have to create a habit of double-checking every time I power these headphones off, that they are completely disconnected from my iPhone, as they frequently just immediately power back on to maintain their connection. I am curious if I am missing something I should be observing here.
