GpNoHeadphonejack The value of not blocking the "charging port" is negligible (especially with wireless charging!). Battery should be plenty for at LEAST all day for a very heavy user, or maybe 2+ for a light user. Headphone dongles are incredibly compact these days, just leave it connected to your headphones and you won't even notice it.
BLE audio should exceed the quality you could expect to get from any phone's headphone jack, and battery life on headphones is quite amazing these days.
