AT A GLANCE

What protection suits your needs?

A slim case may suit those who value grip and lower bulk. A folio can offer extra cover for the outer screen and sometimes a stand function. Either way, the accessory must explicitly fit the intended model.

  1. 01
    Check the exact modelThe stated device name and version should match the accessory.
  2. 02
    Keep the fold clearNothing should strain against the folding mechanism.
  3. 03
    Assess displays separatelyThe outer and inner displays may need different protection.

CHOOSE THE RIGHT FORM

Case or folio?

Both designs can be useful. Your choice depends on whether you prefer a slimmer setup or additional cover for the outer display.

SLIM & GRIPPABLE

Case

Less bulk in daily use

  • Can help protect the back and edges from scratches
  • Often more convenient when opening the device quickly
  • Check hinge clearance and raised-edge design
COVER & STAND

Folio

More cover, more functions

  • May cover the outer display while the device is closed
  • Some designs offer a stand function
  • Check opening angle, weight and closure

COMPATIBILITY

Four checks before buying

“Fits iPhone” is not specific enough. Match the stated compatibility to your model and intended use.

  1. 01

    Exact device name

    Only consider accessories explicitly specifying the intended model.

  2. 02

    Hinge and opening angle

    Edges, flaps and magnetic closures must not interfere with folding.

  3. 03

    Magnetic charging

    Do not assume MagSafe or Qi2 support; verify the listing.

  4. 04

    Material and daily use

    Consider grip, thickness, buttons, camera cut-outs and cleaning.
