Looking to buy a 7 Pro. I have some concerns that i would like feedback on

Right now i'm looking at Pro7 vs Galaxy S10.

First thing is wireless charging, not much to adress here since it's simply a lacking feature. But if any of you guys have tried using a Qi receiver please let me know how good it works.

Secondly and most important, waterproofing. The 7 Pro seems to be totally fine for splashed water, but my main need for waterproofing is shower/bath/pool. Obviously i can't dive with it, but i was wondering if any of you guys use your phone in these scenarios. Mainly wet hands, direct water splashes and accidental submergion (aka dropping your phone) over longer timeframes. I keep my phones for 3-4 years.

Last, the audio jack. Since i travel by train a lot, i 100% need to be able to charge my phone while using my headphones. I've seen a lot of compact dongles around. Any loss on charge speed or sound quality that any of you have experienced? General hassle of a dongle?

Thanks in advance
