Two smartphones (Apple iPhone 14 and Google Pixel 8 Pro) were placed on top of the implantation site, and signs of magnet mode induction were recorded. The Apple iPhone induced magnet mode in seven of 16 (44%) subcutaneously placed CIED. Placed in a magnetic phone case, the Apple iPhone induced magnet mode in six of 16 (38%) devices. Magnet mode induction was successfully prevented in all cases by placing a 1\u2005mm thin steel plate at the back of the smartphone. The Google Pixel did not induce magnet mode in any of the 16 devices, even with a magnetic case. Submuscular CIED placement resulted in no occurrence of magnet mode induction by any smartphone. All devices were still able to be interrogated and responded to a CIED magnet.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>The Apple iPhone induces magnet mode in close to half of subcutaneously placed CIED due to its MagSafe magnet. Neither a smartphone utilizing the Qi wireless charging standard nor magnetic smartphone cases confer the same risk. Submuscular CIED placement or magnetic shielding with a steel plate prevents magnet mode induction. The future Qi2.0 standard may exacerbate interaction risks.<\/jats:p>\n
