About the iPhone 15

  • The iPhone 15 range is one of the most popular choices in our pre owned lineup, offering a strong balance of price and everyday performance. Mintro stocks the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max across a mix of storage options, colours and grades, all photographed individually before sale.
  • Battery health matters more on a phone that has been in use for a while, so we check every iPhone 15 with Blackbelt diagnostic software and print the exact percentage on the listing. Nothing is sold with battery health below 80 percent.

What condition are Mintro's iPhone 15 handsets?

Our grades describe how an iPhone 15 looks, nothing more. Every handset is fully tested and works perfectly regardless of grade. We use three grades: Excellent, Good and Fair.

Excellent Grade A

Looks like new or very close to it, no marks visible under normal light. Battery 90 percent or higher.

Good Grade B

Light scuffs or surface marks only, nothing deep. Battery 85 percent or higher.

Fair Grade C

Obvious cosmetic wear with scratches and scuffs but no cracks, fully working. Battery 80 percent or higher.

How every device is tested before listing

No iPhone 15 goes on sale without a full professional test using Blackbelt diagnostic software. Each handset comes with a Blackbelt Tested Certificate listing the checks carried out, the results and the battery health.

Full functional test (screen, cameras, Face ID, buttons, speakers, connectivity).

Battery health checked and stated.

Activation Lock removed and device wiped.

IMEI/blacklist check.

Cosmetic grade with real photos.

Every iPhone 15 is covered by the 24 month Mintro Guarantee against faults. Accidental damage, water damage and misuse are not covered. It is one of the strongest guarantees on the pre owned market.
