  2. Tap Diagnostics on the Discover tab, or open the app’s Support tab, then choose Phone diagnostics.

Samsung says test names and availability can vary by device and software version. Its current support guide does not give a universal total number of available tests.

Open diagnostics from Settings instead

On Galaxy devices running Android 12 or later, go to Settings > Device care > Diagnostics > Phone diagnostics. This built-in route avoids reinstalling Samsung Members. Availability and menu layout may still differ by model and software version. Samsung documents Samsung Members diagnostics for Galaxy phones and tablets.

  • Weak: Battery efficiency may have decreased through use or environmental conditions.

What a charging test can—and cannot—tell you

A diagnostic result is a useful first check, not proof that a particular component is faulty or a guarantee that a repair is needed. Samsung lists several possible causes of slow or failed charging: the battery, charging cable, power adapter, wireless charger, charging port, moisture detection, and device temperature. A test result should be considered alongside the conditions in which the problem occurs and any guidance shown by the app.

If the test indicates a problem, follow Samsung Members’ on-screen suggestions or related FAQ. For a Bad battery status, seek the support-centre advice Samsung recommends. If charging is still unreliable, remember that the diagnostic result alone may not identify which part or condition is responsible.
