The LED display on the cap shows the real-time temperature of the liquid inside the bottle. The color of the ring around the display indicates the temperature range:
- Blue Ring: Temperature is below 35°C (95°F).

5.3. Activating Self-Cleaning
To manually activate the UV self-cleaning feature:
- Ensure the cap is securely tightened on the bottle.
- Long press the screen on the smart cap. The UV light will activate inside the bottle.
- The self-cleaning cycle will run for a short period.
The bottle also features AI-powered self-cleaning, which automatically activates based on usage patterns to maintain hygiene. A smart safety lock automatically pauses cleaning cycles if the bottle is tilted or the cap is removed, preventing direct exposure to the UV light.

5.4. Hydration Reminders

6. Maintenance
6.1. Cleaning
The bottle body should be hand washed only. Do not place the bottle or cap in a dishwasher. Avoid submerging the smart cap in water to prevent damage to electronic components. The internal UV light provides self-cleaning for the bottle's interior.
6.2. Battery Care
To prolong battery life, charge the bottle regularly. Avoid fully depleting the battery frequently. Store the bottle in a cool, dry place when not in use for extended periods.
7. Troubleshooting
- Bottle not charging: Ensure the USB magnetic charging cable is securely connected to both the cap and a working USB power source. Check if the charging indicator on the cap is active.
- Self-cleaning not activating: Verify that the smart cap is tightly screwed onto the bottle. The safety mechanism prevents UV light activation if the cap is loose or removed. Ensure the battery has sufficient charge.
- Temperature display inaccurate: Make sure the cap is fully and correctly seated on the bottle. Allow a few moments for the sensor to stabilize.
- Water leakage: Check that the smart cap is tightly closed. Inspect the silicone gasket inside the cap for any damage or misalignment.
