Galaxy S25 Ultra vs Galaxy S26 Ultra accessory compatibility

Check Galaxy S25 Ultra case, protector, wireless charger and USB-C accessory reuse with Galaxy S26 Ultra.

Why the answer is conservative

Phone cases are not defined by width, height and depth alone. Camera modules, button positions, speaker openings, microphone holes and corner radii can make a case incompatible even when the published body dimensions are identical. Screen protectors have the same problem with bezel geometry, sensor openings and front-camera areas.

Charging accessories are different: when the connector or charging standard is shared, reuse is more likely. Even then, “works” does not always mean “reaches the new phone's maximum charging speed”.
