Yeah I do a lot of walking and long trips. I had a mid range DSLR and it was horrible carrying it everywhere and juggling lenses and batteries. The iPhone works 90% of the cases perfectly and the last 10% of the cases, I am happy with the compromise.

Edit: The thing that really killed the DSLR for me was lugging the whole kit up Scafell Pike in the pissing rain and cold in the UK. I got some good photos in the morning but carried a brick for the entire day after the battery dumped because of the cold. I had an iPhone XR back then and that kept me going all day fine. When I got back the whole damn camera despite being weather sealed had condensation in it.
