READ BEFORE USING
Make the comparison interpretable
First confirm the standard iPhone 13 and read the wired-charging task. Use only undamaged, compatible accessories. If a safe alternative is unavailable, record that check as not performed.
Baseline: name the cable, adapter and wall outlet you used. Record the charging indicator, battery level if visible, and observation time.
Cable comparison: keep the adapter and outlet unchanged; use a different compatible cable. Record whether the response changed.
Adapter comparison: keep the selected cable and outlet unchanged; use a different compatible adapter. Do not combine this with an outlet change.
If you change the outlet too, give it a separate row. Note a charging pause or temperature warning instead of treating it as the same symptom as no response.
What the result can tell you
A response appears with the other cable — The response changed under that cable condition. This does not establish battery health or prove which part failed.
No response under either safe setup — Both observed conditions and the time spent. Leave internal cause unknown.
Several things changed together — The comparison is inconclusive. Record every change; do not assign the result to one accessory.
No safe spare, or a stop condition — Why the check was not performed. A missing comparison is still useful for service.
