My iPhone 15 has been shutting down and restarting by itself. It started a few months ago as an occasional issue, but now it happens several times a day, sometimes repeatedly within a short period. On a few occasions, the phone has also opened the recovery screen, although it reports no specific problem. Battery health appears normal, and I couldn't find any "panic-full" entries in the Analytics Data. What should I check next, and is this something that needs professional repair?

I checked the battery health and it looks fine. I also searched the Analytics Data but couldn’t find anything labeled “panic-full,” so I’m not sure what else I can inspect myself.
Start by checking Battery Health, since a worn battery can cause unexpected shutdowns even when the phone otherwise seems fine. If the maximum capacity is significantly below 80%, battery service may solve the problem. Also search Analytics Data for files containing “panic-full,” which can point to a hardware sensor or component causing the restarts. Since your battery health looks normal and you aren’t seeing panic reports, the next practical step is having Apple or an authorized repair provider run a hardware diagnostic, especially if the phone is still covered by warranty or device protection.
