How we value your iPhone 11 Pro Max
Valuation factors
Factor | Impact on value |
Model & storage | Higher storage (64GB, 256GB, 512GB) boosts value. The Pro Max usually holds the highest resale value in the 11 series. |
Condition | Cracks, deep scratches, dents or functional issues reduce the valuation. The stainless steel frame marks more easily. |
Battery health | Low battery health is accepted. Devices under ~85% may receive lower offers. |
Market demand | Popular models can attract stronger interest. |
Typical value bands
Category | What to expect |
iPhone 11 Pro Max (Excellent) | Highest payout with minimal wear |
