Is the sony rx10 iv better than a phone?
Yes, for the things a phone struggles with. The RX10 IV has a built-in 8.8-220mm lens, which frames like 24-600mm on full frame. That reach is where it clearly beats a phone: wildlife, sport, and anything across a field. Its 1-inch sensor also gives you better results indoors and at night, and real background blur without the cut-out edges phones produce.
If you mostly take wide, daylight snapshots, your phone is probably fine. The RX10 IV is a bridge camera, so it's bigger than a phone and you'll need to carry it on purpose. For the pros and cons, see Your first camera. If you want a pocket-sized option for travel, check Travel. The newer Sony RX10 V keeps the same zoom and adds a stacked sensor and newer autofocus, so it's worth considering too.
