Another consideration: some apps are locked to the particular device using secure enclave chip so even if you had a full backup of the phone, data, and apps it's possible some apps won't even work on a new phone. You would need to have a second active handset (perhaps the one you retired because the battery was dying?) with some of your apps so a replacement handset for the stolen device can have the ultra-secure app authorized onto the new handset. Right now only one of my apps is this secure but I don't understand why more apps aren't this secure.
