About Device Fit Check

Device Fit Check is an independent utility for deciding which phone accessories are worth trying to reuse after an upgrade.

Phone upgrades create a surprisingly practical question: what can you keep? Device Fit Check turns manufacturer specifications into a simple accessory-by-accessory answer.

The site is independent. It is not owned, sponsored or endorsed by Apple, Google, Samsung or other device manufacturers. Product names are used descriptively to identify the devices being compared.

What we optimize for

Accuracy over certainty, visible sources, a fast no-account experience, and clear separation between a physical fit claim and a standards-based charging claim.
