As previously mentioned, sudden iPhone shutdowns could be due to outdated operating systems incompatible with many current apps. Try updating to a newer iOS version to resolve this.

- Restore to factory settings.
Restoring to factory settings is a highly effective method for resolving many common software conflicts on iPhones. Before initiating this process, ensure to back up your data to prevent any loss.
