Description
At a glance: This refurbished iPhone 15 256GB in Black is a good choice if you want a clean, understated phone with extra room for photos, 4K video, apps and work files. The larger storage is useful if you plan to keep the phone for several years or do not want to manage space too often. It is unlocked, professionally tested, securely data-wiped and supplied with 85%+ battery health, an 18-month device warranty, 12-month battery cover and 30-day returns.
Black is the most discreet finish in the iPhone 15 range and works well for both personal and business use. Because this handset is graded Like New, it should show little to no visible sign of previous use.

Why choose this iPhone 15?
The iPhone 15 gives you USB-C, Dynamic Island and a 48MP main camera in a comfortable 6.1-inch size. With 256GB of storage, there is more room for work files, photos, video and larger apps.
Its A16 Bionic chip is still quick for everyday use. The standard iPhone 15 uses a 60Hz display and does not support Apple Intelligence.
Who is it best for?
This Black 256GB phone suits anyone who uses one handset for both work and personal use, keeps lots of media or plans to own the phone for several years. It gives you more room without moving to a larger or more expensive model.
Our technician insight
On a Black 256GB iPhone 15, our technicians inspect the frame edges, camera rings and USB-C port for rub marks or impact damage. We also test USB-C charging and data transfer, Face ID, cameras, touch response, microphones, speakers and mobile signal.
Phones with more storage are often used heavily for media and work, so we also watch for unusual heat, unstable charging and inconsistent camera behaviour during testing.

Questions about this Black 256GB iPhone
Is 256GB worth it over 128GB?

Does 256GB make the phone faster?
No. The benefit is extra storage, not extra speed.
Does the iPhone 15 use USB-C?
Yes. It uses USB-C for charging and compatible data connections.
