I hope a flagship feature of the next iOS is an "emergency low power mode". Shut down on the last 5% of battery and make that last for 24h or something in that range. Use only dim white on one part of the OLED, show me the time, sound alarms, show important notes, give Wallet/Apple Pay access, allow one last battery draining SOS call and add a compass for good measure. Maybe they could even afford to wake up the radio every 30 minutes and fetch some important info. In a few years they could even open it up to third party developers. If I put my phone in airplane+low power mode, max dim the screen and carefully wake it, 2% already goes for quite a few hours. Maybe they could do way better than 5%/24h even.

Android (and BlackBerry before that) have had something similar to this for a while. On a BlackBerry, it would shut down the radio and give you a "Battery too low for radio use" message, but you could trick it into turning the radios back on by dialing 911 and then hanging up really quickly. Various Android manufacturers do their own version of this, Sony had Ultra STAMINA mode and Samsung have an option to do a whole bunch of power optimizations as well as limit apps to those explicitly specified. For me, the main critical purpose of my phone is to communicate with others in realtime which happens using things like WhatsApp, Slack or Email (maybe the odd call). If I can't use those, then it might as well be dead!
