| Cause | Explanation | |-------|-------------| | | Running a heavy app or game while simultaneously installing an IPA pushes the SoC (System on Chip) past thermal limits. | | Poor environmental conditions | Using the device in direct sunlight, a hot car, or near a radiator. | | Faulty battery | An aging or swollen battery generates excess heat, which trips thermal sensors. The ams1gn daemon is first to be throttled. | | Corrupted IPA file | If the IPA is malformed, ams1gn may enter an infinite loop trying to parse it, generating heat rapidly. | | MDM over-enrollment | Too many simultaneous policies or app pushes can max out the AMS daemon. | | iOS bug | Certain iOS versions (e.g., early iOS 16.x) had known issues where ams1gn would not release CPU cycles after IPA validation ended, causing sustained heat. | ams1gn ipa hot
