Here’s some updated info on that “nfc field only” feature I requested a while back… but more importantly an explaination of why debug mode can be dangerous
“ As @djsime1 said, this has already been implemented.
However, leaving the field on for a long time (more than 20 minutes) actually can damage your device, as the ST25R3916 NFC chip is located directly under the battery, and leaving it on causes it to heat up quite substantially, which unevenly heats up the battery, which is bad for its health and longevity.”
