OUTCOMES Comparison recorded: Record the successful startup and arrange a backup. A single restart success does not explain a recurring shutdown. - Initial and furthest visible screen states - Which button sequence and applicable charging wait were completed - Backup availability before recovery or storage-affecting work Complete the missing preparation: Complete the charging wait that matches the screen observed before interpreting the result. - Match the charging wait to blank-screen versus low-battery behavior. - Initial and furthest visible screen states - Which button sequence and applicable charging wait were completed - Backup availability before recovery or storage-affecting work Discuss the recorded result with support: Give Apple the exact startup state and charging interval. Raise inaccessible or unbacked-up data before any recovery proposal. - Initial and furthest visible screen states - Which button sequence and applicable charging wait were completed - Backup availability before recovery or storage-affecting work Keep the unknowns in your handoff: The correct sequence or charging wait was not completed, so startup response remains unverified. - Tell Apple whether buttons, a usable charger or elapsed charging time prevented the check. - Initial and furthest visible screen states - Which button sequence and applicable charging wait were completed - Backup availability before recovery or storage-affecting work Stop powered checks: Stop using or charging damaged equipment. Do not open or press on the phone or handle hot or smoking equipment. Contact Apple or an authorized provider; use local emergency help for immediate fire danger. - Report any physical damage or abnormal heat before further startup attempts. - Initial and furthest visible screen states - Which button sequence and applicable charging wait were completed - Backup availability before recovery or storage-affecting work SOURCES If your iPhone will not turn on or the screen is black: https://support.apple.com/en-us/116940 (Force your iPhone with Face ID to restart; checked 2026-10-13) If your iPhone will not charge: https://support.apple.com/en-ie/108805 (If your device will not charge, steps 1–8; checked 2026-10-13) Important safety information for iPhone: https://support.apple.com/guide/iphone/important-safety-information-iph301fc905/26/ios/26 (Handling; Repairing; Battery; Charging; checked 2026-10-13) Identify your iPhone model: https://support.apple.com/en-ie/108044 (Find the model name / iPhone 13; checked 2026-10-04) iPhone 13 technical specifications: https://support.apple.com/en-ie/111872 (External Buttons and Connectors; Power and Battery; checked 2026-10-13) Prepare iPhone for a service appointment: https://support.apple.com/en-us/109519 (Get ready; Bring in; Get back from service; checked 2026-10-13) This is a blank guide.
