airplane mode should reduce maximum charge level to 90% and charging speed. now that would be easy to implement but you run the risk of people switching off airplane mode to get a full charge. still seems like a good idea because people already don't care about their GSM and other phone radiofrequency emissions.
people who are nice which is a bunch will still put the phone in airplane mode therefore reducing charging rate/max charge level reducing the likelihood of thermal runaways.
