My Jabra Stealth gets drained out of power after 4-5 hours while just being connected with XZ Premium, exactly as if I was listening to music or having calls. Yes, I did Factory reset, nothing changed, not in Safe mode too. With my old Z3 there was and is (I tried it today) no such issues whatsoever.
Don't get me wrong, I love the looks of my XZ Premium in chrome color from the very first sight. But there are several issues that have to be addressed. Guys from Sony, can you just get back all the Bluetooth solutions that you used at my still working cool Z3?
