iPhone 13 Used Battery & Hardware Advice
I bought a used iPhone 13 with 85% battery health. What tests should I perform ? The battery cycle count is 758, and 3uTools shows no errors. How long should the battery last on a full 100% charge?
Also, the EID on the phone is different from the one on the box. Is this acceptable?
I need help checking everything while it is still under the checking warranty.
