Record warning, workload and recovery after cooling without deliberately reproducing overheating.

MODEL FIT
Open Settings → General → About. Read Model Name: it must say iPhone 13. Do not enter the serial number here.
iOS 15 or later; use the support page matching your installed iOS for service settings.
Excluded: iPhone 13 mini; iPhone 13 Pro; iPhone 13 Pro Max; iPhone 15

PREPARATION
[ ] No swelling, smoke or physical damage
[ ] A cooler shaded place is available
[ ] Only normal device observations; no temperature probe required
[ ] Keep any existing backup accessible to you.
[ ] Keep credentials and personal files outside this record.

GUIDE
1. Record what appeared: Charging On Hold, dimmed screen, a temperature warning or an unexpected shutdown. Warmth alone and an onscreen warning are different observations.
Sources: https://support.apple.com/en-us/118431; Device gets too warm; Charging On Hold; warning screen
2. Select the activity that was already occurring, such as charging, navigation, camera use or setup. Do not recreate heavy load to generate another warning.
Sources: https://support.apple.com/en-us/118431; Conditions that can cause warmth
3. For a temperature warning, turn the phone off, move away from sun or heat and let it cool. Stop active use while cooling.
Sources: https://support.apple.com/en-us/118431; If a temperature warning screen appears
4. After it has cooled, observe ordinary use. Record whether brightness or charging returns; there is no fixed cooling countdown that proves safety.
Sources: https://support.apple.com/en-us/118431; Normal behavior resumes after cooling
5. If the same warning returns in normal cooler conditions, save the recurrence and contact Apple. A charging pause near a high charge level alone does not identify battery failure.

EVIDENCE TO RECORD
Observed indication: Not recorded
Activity before event: Not recorded
Environment: Not recorded
After cooling: Not recorded
Ordinary use before event — Historical observation only; do not reproduce heat: Not checked
Ordinary use after cooling — No warning present; comfortable handling: Not checked
Charging after cooling — Only when safe; original compatible setup: Not checked

STOP CONDITIONS
Stop using and charging equipment with swelling, casing separation, smoke, a burning smell or suspected battery damage. Do not open or press on it.
Set damaged accessories aside. Do not open mains adapters or force connectors.
Do not erase, reset, flash firmware or bypass a lock as a default diagnostic step.

OUTCOMES
Comparison recorded: Keep the activity and warning record. A recovered temperature restriction is a useful observation, not a full battery-health assessment.
- Exact warning category and activity already in progress
- Charging connection and environment category
- Return to normal or recurrence after cooling
Complete the missing preparation: Leave the phone out of heat and allow cooling before normal use. Do not repeat heavy activity to test the limit.
- Allow cooling in a shaded ventilated place; no forced rapid-cooling technique is needed.
- Exact warning category and activity already in progress
- Charging connection and environment category
- Return to normal or recurrence after cooling
Discuss the recorded result with support: Tell Apple which warning or shutdown returned in cooler ordinary use and whether charging was connected.
- Exact warning category and activity already in progress
- Charging connection and environment category
- Return to normal or recurrence after cooling
Keep the unknowns in your handoff: No safe post-cooling observation exists yet. Preserve the initial warning and leave recovery unknown.
- Tell the provider whether the warning cleared and whether later ordinary use was observed.
- Exact warning category and activity already in progress
- Charging connection and environment category
- Return to normal or recurrence after cooling
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 smoke, casing change or suspected battery damage rather than treating it as ordinary warmth.
- Exact warning category and activity already in progress
- Charging connection and environment category
- Return to normal or recurrence after cooling
