A digital camera always holds an upper hand over and i-phone. People often prefer to own an i-phone for a better picture quality, but it has certain limitation when it comes to pixels or battery life.

I must say that phone camera's nowadays really deliver quite good photographs nowadays. I make a lot of my photos with my smartphone too. I always say it's not the camera, but the photographer that makes the photo.

When I bring my 'real' camera I do pay more attention to make a nice shot. Where I use my smartphone to capture opportunities, I take my 'real' camera when I go out to shoot photos.

Also 'real' camera's do give you more options and, especially when you are able to switch lenses, you have way more possibilities. But it's the question whether you would like that, because it also can be a hussle for instance changing lenses and bringing them along.
But if you really want to make a next step and don't want to go for an expensive DSLR (Digital Single-Lens Reflex) camera, a mirrorless camera might be an option.
I've been using my (midrange) Canon M50 for a couple of years now and am very happy with it. I have bought a second lens which I use for zooming and macro shots (in combination with extension rings).
The pricing is in between DSLR's and your powershot, but it gives you way more possibilities. The camera and eventually 1 or 2 extra lenses do require a small camera bag (not a backpack like you need with a DSLR).

I hope this info helps you a bit.
