Diagnosis
This is often a false reading caused by a poor connection between the battery and the camera's internal contacts, or the battery itself needing a 're-seat'.
How to Fix It
Power cycle and re-seat the battery. 1) Remove the battery from the camera by pulling down the weatherproof seal and sliding it out. 2) Press and hold the small button on the battery itself for 10 seconds. 3) Reinsert the battery firmly until you hear a click, ensuring the seal is fully back in place. 4) Check the Device Health in the app again after a few minutes.
If That Didn't Work
Try a different charging cable and wall adapter to fully charge the battery outside the camera. A faulty charger can make the battery *seem* full but not actually hold a proper charge.
Heads Up
Only use the official Ring battery or a high-quality third-party replacement that matches the specs. Non-standard batteries can cause this error and even damage the camera.
