Device Life Checker

What the Device Life Checker can—and cannot—estimate

Device age is useful when planning maintenance, resale or replacement, but age alone cannot reveal the true health of a battery, display, storage device or motherboard. This tool uses the purchase and age information you enter to create a planning estimate rather than claiming to read hidden hardware health.

For a more reliable result

• Use the original purchase or manufacturing period if you know it, rather than guessing from when you first received a used device.
• Combine age with real symptoms such as battery runtime, display defects, storage warnings, overheating or unreliable charging.
• For a used phone or laptop, run the screen, touch, keyboard, camera, microphone and audio tests as separate checks.
• Manufacturer service diagnostics or battery-health tools are more appropriate when you need component-specific health data.

What this test cannot confirm

The result is not a warranty decision, failure prediction or guarantee of remaining life. Two devices of the same age can have very different conditions because of usage, environment and repair history.
