Robot mower’s app shows incorrect battery percentage or jumps suddenly from high to low.

Safety: Normal operation; no additional safety steps beyond standard handling.

• Perform full discharge/charge cycle: Allow the mower to run until it returns to the dock with a low battery, then charge it uninterrupted to 100%.
• Update firmware: Use the Yarbo app to install any available updates that may improve battery reporting.
• Monitor runtime: Compare displayed percentage to actual runtime. If runtime is very short, the battery itself may be degraded.
