If Your Apple devices restarts in 3 minutes interval, Here is the technical explanation for this
Technically this is called panic error. When there is a failure in hardware, if the device is restarted it will create a panic report file in the settings
By decoding this file we will get the exact problem of the device
Panic error logs can be decoded in many ways
We can decode it manually by opening he panic file in settings –> privacy & security –> analytics & improvements –> Analytics data –> here you will get a file named panic; decode this file manually by understanding the error keywords. need technical knowledge for the decoding
Another option is connecting the device in iDevice panic analyser software, which is a free software to decode panic reports,
Another option is more accurate, connect device in JCDraw software and wait for the panic issues and their solutions to appear.
Do hardware solutions according to the panic issues
iPhone 13 and later models shows SMC assertion type panic errors

SMC (System Management Controller) assertion type panics – iphone 13 and above
In iPhones and other Apple devices, SMC (System Management Controller) panics are typically logged during hardware-related faults, and these logs include assertion type panics with hex codes. These hex codes appear in crash logs, and they usually indicate specific hardware failures or sensor inconsistencies, particularly related to power, thermal sensors, or charging circuits.
Below is a guide to common iPhone SMC assertion panic hex codes, their meaning, and possible solutions:
| Assertion Type Hex Code | Meaning | Possible Cause | Solution |
| 0x8 (or 0x00000008) | Missing or invalid battery or battery data | Faulty battery, connector, or missing BMS EEPROM | Replace battery, check flex cable or battery data line |
| 0x10 | Battery temperature sensor missing or out of range | Sensor line damage, battery issue | Replace battery or reball sensor IC |
| 0x20 | Charging circuit fault / Tigris / Tristar failure | Charging IC issue, Tristar damage | Replace Tigris/Tristar, check diode paths |
| 0x40 | Gas gauge (battery monitoring) communication failure | Battery gas gauge IC failure | Replace battery or check SMBus (I2C) lines |
| 0x80 | PMIC fault or missing voltage rail | PMU-related failure | PMIC replacement, check all power rails |
| 0x100 | Thermal sensor on board (not battery) failed or missing | Overheating component, sensor open/short | Replace or reball thermal sensor, inspect for overheating components |
| 0x200 | Overcurrent or power draw issue | Shorted component or faulty IC | Diagnose with thermal camera, remove short |
| 0x400 | VDD_MAIN or main power rail unstable or out of spec | Main power line short, bad filter | Check current draw, inspect for shorts or PMIC failure |
| 0x800 | Audio amplifier/power supply issue | Loudspeaker amp short or related IC issue | Replace audio codec or amp |
| 0x1000 | Wi-Fi or baseband-related power issue | BBPMU, RF power rail issue | Replace Wi-Fi module or baseband PMU IC |
Battery-related (0x8, 0x10, 0x40):
- Try a known good battery.
- Inspect battery connector under microscope.
- Reflow or reball battery sensor-related components.
Charging faults (0x20, 0x80, 0x400):
- Check Tristar (U2 IC), Tigris, Hydra, or USB ICs.
- Use USB ammeter to check current draw.
- Inspect VBUS, VDD_MAIN, PP5V0 lines.
Thermal sensor faults (0x100, 0x200):
- Use schematic/boardview to locate sensors.
- Reball or replace sensor IC.
- Inspect for physical or liquid damage.
| Sensor codes | Problem |
| 0x400 | bottom board issue (iPhone 13 mini only) |
| 0x800 | charge port assembly |
| 0x1000 | front facing sensor cable. |
| 0x4000 | part of the battery |
Sensor codes for the iPhone 14 are as follows:
| Sensor codes | Problem |
| 0x20000 | sandwich board issue |
| 0x40000 | charging port flex |
| 0x80000 | proximity flex cable |
| 0x100000 | power button flex |
