Anyone use a cell phone dedicated for Ecoflow App?

With all of the connection issues I have had with the App and my Delta 2 Max. I had a thought, maybe I am better off buying a modern Android phone with the latest radios and use this exclusively to control Ecoflow units? Perhaps something in expensive but has newer Bluetooth and WiFi protocols than my Iphone 13

My Iphone 13 is getting old and I am planning on upgrading on the next release but for now, perhaps this will help with my connection issue?

Is anyone doing something similar?
