I suggest you seek funding for your new phone that requires Bluetooth headphones for music or to listen to calls, a Bluetooth Mic, and a wireless charger that you have to carry with you wherever you go. I wish you all the best. In the meantime, those of us in the real world of consumer choices will have to risk water damage as a result of our inferior phones that expose the phones insides to water (when dropped in a toilet or pool).
I suggest you look into careful reading; I never suggested blue tooth for use of the phone as a phone. It’s a simple matter to put a waterproof membrane over both the speaker and the mouth piece. Wireless chargers were sold for the iPhone by Brookstones two or three years ago; it is well established technology. The only change I suggested would be Bluetooth to external speaker, again well established technology.
Careful reading is a valuable life skill, you might want to look into it
