Where to find the panic log on an iPhone

Last updated: October 21, 2026

When an iPhone restarts by itself, iOS writes down what happened just before: a panic log. It is the most useful clue you have, and it is already on the phone.

Open Analytics Data

1. Open Settings › Privacy & Security.
2. Scroll to the end and tap Analytics & Improvements.
3. Tap Analytics Data.

The list holds many files written by iOS and by apps, sorted by name.

Find the panic-full file

Look for files whose name starts with panic-full, followed by a date and time, for example panic-full-2026-10-13-123912.ips. iOS leaves one each time the iPhone restarts by itself. Open the one with the latest date: it describes the most recent restart.

No panic-full file in the list means iOS has not recorded a panic since its logs were last cleared. A restart you started yourself, or one caused by an update, leaves none.

Open it in PhoneBox

• Share it: open the file, tap Share, then choose PhoneBox. PhoneBox opens Panic analyzer on it. If PhoneBox is not in the row, swipe to the end, tap More, and add it.
• Paste it: select the text of the log, copy it, and tap Paste in Panic analyzer.
• From Files or AirDrop: a .ips file saved in Files or sent from another device opens in PhoneBox too.

PhoneBox reads the log on your iPhone and tells you in plain words what failed, which part is most likely behind it on that model, and how sure that is. Your logs never leave your iPhone.

Only have a code?

A repair shop or a forum may give you only a fragment, such as 0x200000 or a sensor name. Type it in Only have a code? on Panic analyzer to see what it means on each model.
