  • That is a battery sensor failure, did you recently have the battery replaced or had the iPhone opened for any reason?
  • What is your Battery Health percentage at Settings > Battery > Battery Health?


It is noted by the decimal value of 5242880 in your Panic Log identifying the sensor as the Battery sensor with the equivalent value of 0x500000 as seen in this article:
