Bottom. It slows accumulation of pocket lint in charging port.

Yes

I like having it on top for being able to set my phone up against something still, but if it’s in my pocket I want the top of my phone down so I take it out it’s right, which means the bottom Jack works better. So ideally I’d want both

The side

All phones I've had, had the jack on the bottom where it's in the way of me holding the phone or placing the phone on something. I always wondered why it's not just at the top.

BTW just got a new phone (Oneplus) and I'm glad to have found one that has a jack at all

Top right.
It's best place when holding it in landscape mode.

bottom, so I can charge it and have headphones plugged in at the same time while it's in my pocket.

I had the last generation iPod nano, and none of the clip-on cases I could find would put it upside down like the way I preferred my phone so I cut it with an exacto knife to reverse it

Ever since I've gotten some decent noise cancelling Bluetooth headphones, I don't really care where the headphone jack is or even if there is one. It happened way too many times that the cable got snagged on something and yanked the buds out of my ears, and I'm well past the age where I had the cable under my shirt and the earbuds dangling in front of me all the time. Especially when running or otherwise exercising, I don't miss the cable one tiny bit.

What privacy respecting phone are you using that also has a headphone jack? If it has an sd card slot too I'll think I've gone back a decade

Anywhere but the bottom half of the phone. I hate that the charging port is on the bottom. It’s in the way when I need to use my phone while charging.

I don't really care because I rotate my screen 180 degrees in landscape if it's on the bottom and I'm using headphones
