Should I upgrade my DSLR?

A comparison between Sony A6400 and iPhone 13 shows the latter has strengths that I, the horrible photographer, would benefit. 

So my phone is iPhone 13 Pro, if compare to A6400 should be better right? 

But it’s that thoughts of wanting an DSLR to capture nice scenic shots and astrophotography. 

Then again, it seems the iPhone is able to take astrophotography as well 🤣. 

Want a DSLR but current canon 650D which is so old weighs 575g + whatever good lenses (which makes hella no difference to my skills) is really cumbersome if I want to climb up rocks. Will be worried about camera smashing against the rocks. 

Sigh…. Should I upgrade?
