i googled this and found not a single thing. Every Bluetooth device I have beeps then shuts down at 20% battery. I have two earbuds (different brands) and two Bluetooth receivers (the kind you plug into wired headphones or your car). Why do these devices shut down with 1/5 battery remaining?? Because this is multiple devices across do...is this an iOS thing? If so how do I change it?
